+
+InsightFlow AI is designed to help you explore complex topics with depth and clarity by providing multiple AI-driven perspectives, synthesizing them into a coherent understanding, and even offering visual summaries. Think of it as your personal team of AI research assistants!
+
+## What Can InsightFlow AI Do?
+
+*   **Multi-Perspective Analysis:** Instead of a single answer, InsightFlow AI engages a team of specialized AI "personas" (e.g., Analytical, Philosophical, Scientific) to examine your query from different angles. This provides a richer, more nuanced understanding.
+*   **Insight Synthesis:** The individual perspectives are then intelligently combined into a single, comprehensive synthesized response.
+*   **Visualizations (Optional):**
+    *   **DALL-E Sketches:** Get a conceptual, hand-drawn style visual note summarizing the key ideas.
+    *   **Mermaid Diagrams:** See a concept map illustrating the relationships between your query, the personas, and the synthesized view.
+*   **RAG (Retrieval Augmented Generation - for supported personas):** For certain personas, the AI can search a dedicated knowledge base of relevant documents to ground its responses in specific information, enhancing accuracy and depth.
+*   **Flexible Interaction Modes:**
+    *   **Full Multi-Persona Mode:** The default mode, engaging your selected team for in-depth analysis.
+    *   **Direct Mode:** Get a quick, straightforward answer from a single LLM, bypassing the multi-persona/LangGraph system.
+    *   **Quick Mode:** A faster multi-persona analysis using a reduced set of (currently 2) predefined personas.
+*   **Exportable Results:** You'll be able to export your analysis (though this feature is still under full development).
+
+## Why Does It Work This Way? (The Philosophy)
+
+InsightFlow AI is built on the idea that complex topics are best understood by examining them from multiple viewpoints. Just like a team of human experts can provide more comprehensive insight than a single individual, our AI personas work together to give you a more well-rounded and deeply considered response. The structured workflow (managed by LangGraph) ensures a methodical approach to generating and synthesizing these perspectives.
+
+## Using the Settings (⚙️ Gear Icon)
+
+You can customize your InsightFlow AI experience using the settings panel:
+
+*   **⚙️ Enable RAG Features:**
+    *   **Functionality:** (Currently being refined) When enabled, personas designated as "RAG-enabled" (like Analytical, Philosophical, Metaphorical on the Balanced Team) will attempt to search their specific knowledge bases for relevant context before generating their perspective. This can lead to more informed and detailed answers.
+    *   **Status:** Basic RAG data loading and vector store creation for personas is active. The quality and breadth of data sources are still being expanded.
+
+*   **🎯 Persona Team:**
+    *   **Functionality:** Allows you to quickly select a pre-configured team of personas. Selecting a team will override any individual persona toggles below.
+    *   **Current Teams:**
+        *   `🎨 Creative Synthesis Team`: (Metaphorical, Futuristic, Philosophical) - Generates novel ideas and artistic interpretations.
+        *   `📊 Data-Driven Analysis Squad`: (Analytical, Factual, Scientific) - Focuses on factual accuracy and logical deduction.
+        *   `⚖️ Balanced Overview Group`: (Analytical, Philosophical, Metaphorical) - **This is the default team on startup.** Provides a well-rounded perspective.
+    *   **Status:** Team selection is functional.
+
+*   **Individual Persona Toggles (e.g., Analytical, Scientific, etc.):**
+    *   **Functionality:** If no team is selected (or "-- Select a Team (Optional) --" is chosen), you can manually toggle individual personas ON or OFF to form a custom team for the analysis.
+    *   **Status:** Functional.
+
+*   **🚀 Direct Mode:**
+    *   **Functionality:** If ON, your query will be answered by a single, general-purpose LLM for a quick, direct response, bypassing the multi-persona/LangGraph system.
+    *   **Status:** Functional.
+
+*   **⚡ Quick Mode:**
+    *   **Functionality:** If ON, InsightFlow uses a smaller, predefined set of personas (currently Analytical and Factual) for a faster multi-perspective analysis. This overrides team/individual selections when active.
+    *   **Status:** Functional.
+
+*   **👁️ Show Individual Perspectives:**
+    *   **Functionality:** If ON (default), after the main synthesized response, the individual contributions from each engaged persona will also be displayed.
+    *   **Status:** Functional.
+
+*   **🎨 Show Visualizations:**
+    *   **Functionality:** If ON (default), InsightFlow will attempt to generate and display a DALL-E image sketch and a Mermaid concept map related to the synthesized response.
+    *   **Status:** Functional (DALL-E requires API key setup).
+
+## Getting Started
+
+1.  **Review Settings (⚙️):** Select a Persona Team or toggle individual personas. Ensure RAG is enabled if you want to try it with supported personas.
+2.  **Ask Your Question:** Type your query into the chat and press Enter.
+3.  **Observe:** Watch the progress updates as InsightFlow AI engages the personas, synthesizes insights, and generates visualizations.
+
+We hope you find InsightFlow AI insightful!

+When we examine this problem carefully, several key patterns emerge. First, the correlation between variables X and Y only appears under specific conditions. Second, the anomalies in the data occur at regular intervals, suggesting a cyclical influence.
+
+The evidence suggests three possible explanations. Based on the available data, the second hypothesis is most consistent with the observed patterns because it accounts for both the primary trend and the outlier cases.

+When we talk about algorithms making decisions, we're not just discussing abstract mathematics – we're talking about systems that increasingly determine who gets a job, who gets a loan, and sometimes even who goes to prison. The math matters because its consequences are profoundly human.
+
+The fascinating thing about probability is how it challenges our intuition. Take the famous Birthday Paradox: in a room of just 23 people, there's a 50% chance that at least two people share a birthday. With 70 people, that probability jumps to 99.9%.
+
+Data never speaks for itself – it always comes with human assumptions baked in. When we look at a dataset showing correlation between two variables, we need to ask: what might be causing this relationship?

+Title: The Illusion of Algorithmic Objectivity
+
+Modern analytical processes increasingly rely on algorithms to process vast datasets and derive insights, from financial modeling to public policy recommendations. A common misconception is that these algorithmic outputs are inherently objective, free from the biases that plague human decision-making. However, this overlooks a critical truth: algorithms are human creations, and data is a human-curated artifact.
+
+Bias can be introduced at multiple stages. Firstly, the data itself may reflect historical societal biases. For example, if an algorithm for loan approval is trained on historical data where certain demographic groups were unfairly denied credit, the algorithm may learn and perpetuate these discriminatory patterns, even if the demographic variables themselves are excluded. The 'objective' algorithm simply becomes a more efficient enforcer of past injustices.
+
+Secondly, the choice of features included in a model, the definition of success metrics, and the very problem an algorithm is designed to solve are all human decisions laden with implicit assumptions and values. An analytical model designed to optimize for 'efficiency' in public transport routing might inadvertently disadvantage communities with fewer resources or less political clout if 'efficiency' is defined purely by speed or cost without considering equity of access.
+
+Thirdly, the interpretation of algorithmic outputs requires human judgment. Correlation does not imply causation, yet complex models can produce spurious correlations that an uncritical analyst might misinterpret as meaningful. The analytical task, therefore, is not merely to run the numbers but to interrogate the entire process: the provenance of the data, the assumptions embedded in the model, and the potential societal impact of the conclusions drawn. True analytical rigor in the age of AI demands a deep understanding of both the mathematical underpinnings and the socio-ethical context of these powerful tools. Without this, we risk amplifying bias under a veneer of computational neutrality.

mathematics of love by Hannah Fry at TEDxBinghamtonUniversity</a></span></strong></p><p><strong><span style="text-decoration: underline;">TRANSCRIPT: </span></strong></p><p>Thank you very much. So, yes, I&#8217;m Hannah Fry. I am a mathematician. And today I want to talk to you about the <em>mathematics of love</em>. Now, I think that we can all agree that mathematicians are famously excellent at finding love. But it&#8217;s not just because of our dashing personalities, superior conversational skills and excellent pencil cases. It&#8217;s also because we&#8217;ve actually done an awful lot of work into the maths of how to find the perfect partner.</p><p>Now, in my favorite paper on the subject, which is entitled, <em>&#8220;Why I Don&#8217;t Have a Girlfriend&#8221;</em> &#8212; Peter Backus tries to rate his chances of finding love. Now, Peter&#8217;s not a very greedy man. Of all of the available women in the U.K., all Peter&#8217;s looking for is somebody who lives near him, somebody in the right age range, somebody with a university degree, somebody he&#8217;s likely to get on well with, somebody who&#8217;s likely to be attractive, somebody who&#8217;s likely to find him attractive. And comes up with an estimate of 26 women in the whole of the UK. It&#8217;s not looking very good, is it Peter?</p><p>Now, just to put that into perspective, that&#8217;s about 400 times fewer than the best estimates of how many intelligent extraterrestrial life forms there are. And it also gives Peter a 1 in 285,000 chance of bumping into any one of these special ladies on a given night out.

+What the data says about Americans’ views of artificial intelligence
+​
+ Summarize
+​

+(d3sign/Getty Images)
+From detecting cancer on a medical scan to drafting an essay for a school assignment, artificial intelligence is increasingly shaping the way Americans live.
+
+Pew Research Center surveys show that Americans are increasingly cautious about the growing role of AI in their lives generally. Today, 52% of Americans are more concerned than excited about AI in daily life, compared with just 10% who say they are more excited than concerned; 36% feel a mix of excitement and concern.
+
+Despite these cautious overall views, Americans see some specific uses of AI positively, and attitudes depend a great deal on the context of how and why AI is being used.
+
+This post summarizes what we know so far about how Americans view AI in everyday life, the workplace, and health and medicine.
+
+Public awareness of AI
+
+The vast majority of Americans (90%) say they’ve heard at least a little about artificial intelligence, according to an August 2023 survey. However, only one-in-three say they’ve heard a lot about it.
+
+While most people are aware of AI, Americans’ ability to identify specific uses of the technology is still developing. Only 30% of U.S. adults correctly recognize all six examples of AI in everyday life that we asked about in a December 2022 survey.
+
+And not everyone brings the same level of understanding. Adults with a college or postgraduate degree are more likely to be familiar with AI than those with less education. There are also significant differences by gender and age, with men and younger adults being more familiar with AI than women and older adults.
+
+Views and experiences with ChatGPT
+
+Generative AI, or programs that can produce text and images, garnered wide media attention in 2023. One prominent example of this technology is ChatGPT. We found in March 2023 that 58% of U.S. adults have heard of ChatGPT, while 42% have heard nothing at all about it.
+
+As with awareness of AI generally, familiarity with ChatGPT is higher among men, younger adults and those with a college or postgraduate degree. 
+
+Even though a majority of Americans are aware of the program, firsthand experience with it is relatively uncommon. Just 18% of all U.S. adults say they’ve used ChatGPT.
+
+AI in schooling
+
+We asked U.S. teens ages 13 to 17 about the program in a fall 2023 survey. We found that 67% are familiar with ChatGPT. And 19% of those teens say they have used it to help with their schoolwork.
+
+Most teens who’ve heard of ChatGPT say it’s acceptable to use ChatGPT to research new things (69%). But fewer say the same about using it for things like solving math problems (39%). And a majority (57%) say it is not acceptable to use it to write essays.
+
+Views of AI in the workplace
+
+In 2022, 19% of American workers were in jobs that are most exposed to AI, based on a Center analysis of government data. Those jobs tend to be in higher-paying fields where a college degree and analytical skills can be a plus.
+
+Our December 2022 survey shows 62% of Americans believe AI will have a major impact on workers generally. However, far fewer think it will impact them personally in a major way (28%).
+
+A majority of U.S. adults oppose using AI to make final hiring decisions or track workers’ movements on the job. In fact, 66% of Americans say they would not want to apply for a job with an employer who uses AI to help with hiring decisions. But there’s more openness to using AI in other ways, like monitoring workers’ driving while they make trips for work or tracking attendance.
+
+Views of AI in health and medicine
+
+Health and medicine is one area where many Americans may encounter artificial intelligence. AI is increasingly being used to do things like help diagnose disease and recommend treatment.
+
+Yet six-in-ten Americans say they would feel uncomfortable with their health care provider relying on AI to help care for them.
+
+More broadly, the public is divided on the impact of AI in health and medicine. While 38% say it will lead to better outcomes for patients, 33% say it will lead to worse outcomes and 27% say it won’t make much difference. One widely expressed concern is that AI will make patients’ personal relationships with their providers worse.
+
+While Americans are cautious about the use of AI in health and medicine generally, they support some specific uses. For instance, 65% say they would want AI to be used in their own skin cancer screening. Studies have found some AI software to be highly accurate at detecting skin cancer.
+
+Support for oversight and regulation of AI
+
+By and large, Americans back regulation and oversight of emerging AI technologies, including chatbots and driverless vehicles.
+
+For example, 67% of those who are familiar with chatbots like ChatGPT say they are more concerned that the government will not go far enough in regulating their use than that it will go too far. A much smaller share (31%) takes the opposite view.
+
+When it comes to AI-powered driverless vehicles, 87% of Americans want them held to a higher testing standard than other passenger vehicles. Americans also commonly express unease around the unanticipated consequences and risks of these technologies. About three-quarters (76%) think it’s likely that the computer systems in driverless vehicles could be easily hacked, putting safety at risk.
+
+A related concern is over the pace of AI adoption in society. In health and medicine, for instance, 75% of Americans think health care providers will move too fast using AI, before fully understanding the potential risks.
+
+Common concerns – and sources of excitement – about AI
+
+While the specific uses of AI matter a lot in how Americans feel about it, we see some common themes in what people like and don’t like about AI.
+
+On the positive side
+
+There are generally higher levels of support for AI when it is used to help with routine or basic tasks. A majority (57%) of Americans say they would be excited for AI to perform household chores, while just 19% express concern about this. Saving time or helping handle mundane tasks are also common reasons for excitement about AI.
+
+Americans are also pretty positive when it comes to AI’s ability to help people find products and services they are interested in online. 
+
+And while experts debate how AI will influence bias in society around things like race and gender, there are signs that the public is more optimistic than pessimistic. For example, among U.S. adults who see a problem with racial and ethnic bias in health and medicine, more think the use of AI would make the issue of bias better than worse (51% vs. 15%). Similarly, among those who see bias in hiring as an issue, more think AI would improve the problem of bias based on job applicants’ race or ethnicity than say it would worsen it (53% vs. 13%).
+
+On the negative side
+
+There’s broad concern about the loss of the human element due to emerging AI technologies, especially in settings like the workplace and health care. Many Americans who would not want to apply for a job that uses AI in the hiring process cite a lack of the “human factor” in hiring as the reason why. In health and medicine, a majority of Americans think relying more on AI would hurt patients’ relationships with their providers.
+
+The potential for negative impacts on jobs is another common concern with AI. Among those who say they’re more concerned than excited about AI, the risk of people losing their job is cited most often as the reason why. We also see this concern with some specific examples of AI. For example, 83% of Americans think driverless cars would lead to job loss for ride-share and delivery drivers.
+
+Surveillance and data privacy are also concerns when discussing AI. Large majorities of Americans who are aware of AI think that as companies use AI, personal information will be used in unintended ways and ways people are not comfortable with.

+The Fine Art of Baloney Detection
+Carl Sagan
+The human understanding is no dry light, but receives an infusion from the will and affections;
+whence proceed sciences which may be called “sciences as one would.” For what a man had rather
+were true he more readily believes. Therefore he rejects difficult things from impatience of research;
+sober things, because they narrow hope; the deeper things of nature, from superstition; the light
+of experience, from arrogance and pride, lest his mind should seem to be occupied with things
+mean and transitory; things not commonly believed, out of deference to the opinion of the vulgar.
+Numberless in short are the ways, and sometimes imperceptible, in which the affections colour
+and infect the understanding.
+Francis Bacon, Novum Organon (1620)
+My parents died years ago. I was very close to them. I still miss them terribly. I know I always will. I long to
+believe that their essence, their personalities, what I loved so much about them, are—really and truly—still in
+existence somewhere. I wouldn’t ask very much, just five or ten minutes a year, say, to tell them about their
+grandchildren, to catch them up on the latest news, to remind them that I love them. There’s a part of me—no
+matter how childish it sounds—that wonders how they are. “Is everything all right?” I want to ask. The last words
+I found myself saying to my father, at the moment of his death, were “Take care.”
+Sometimes I dream that I’m talking to my parents, and suddenly—still immersed in the dreamwork—I’m
+seized by the overpowering realization that they didn’t really die, that it’s all been some kind of horrible mistake.
+Why, here they are, alive and well, my father making wry jokes, my mother earnestly advising me to wear a
+muffler because the weather is chilly. When I wake up I go through an abbreviated process of mourning all over
+again. Plainly, there’s something within me that’s ready to believe in life after death. And it’s not the least bit
+interested in whether there’s any sober evidence for it.
+So I don’t guffaw at the woman who visits her husband’s grave and chats him up every now and then, maybe
+on the anniversary of his death. It’s not hard to understand. And if I have difficulties with the ontological status
+of who she’s talking to, that’s all right. That’s not what this is about. This is about humans being human. More
+than a third of American adults believe that on some level they’ve made contact with the dead. The number
+seems to have jumped by 15 percent between and 1988. A quarter of Americans believe in reincarnation.
+But that doesn’t mean I’d be willing to accept the pretensions of a “medium,” who claims to channel the
+spirits of the dear departed, when I’m aware the practice is rife with fraud. I know how much I want to believe
+that my parents have just abandoned the husks of their bodies, like insects or snakes molting, and gone
+somewhere else. I understand that those very feelings might make me easy prey even for an unclever con, or for
+normal people unfamiliar with their unconscious minds, or for those suffering from a dissociative psychiatric
+disorder. Reluctantly, I rouse some reserves of skepticism.
+How is it, I ask myself, that channelers never give us verifiable information otherwise unavailable? Why does
+Alexander the Great never tell us about the exact location of his tomb, Fermat about his Last Theorem, John
+Wilkes Booth about the Lincoln assassination conspiracy, Hermann Goring about the Reichstag fire? Why don’t
+Sophocles, Democritus, and Aristarchus dictate their lost books? Don’t they wish future generations to have
+access to their masterpieces?
+If some good evidence for life after death were announced, I’d be eager to examine it; but it would have to be
+real scientific data, not mere anecdote. As with the face on Mars and alien abductions, better the hard truth, I say,
+than the comforting fantasy. And in the final tolling it often turns out that the facts are more comforting than the
+fantasy.
+The fundamental premise of “channeling,” spiritualism, and other forms of necromancy is that when we die
+we don’t. Not exactly. Some thinking, feeling, and remembering part of us continues. That whatever-it-is—a soul
+or spirit, neither matter nor energy, but something else—can, we are told, re-enter the bodies of human and other
+beings in the future, and so death loses much of its sting. What’s more, we have an opportunity, if the spiritualist
+or channeling contentions are true, to make contact with loved ones who have died.
+J. Z. Knight of the State of Washington claims to be in touch with a 35,000-year-old somebody called
+“Ramtha.” He speaks English very well, using Knight’s tongue, lips and vocal chords, producing what sounds to
+me to be an accent from the Indian Raj. Since most people know how to talk, and many—from children to 
+professional actors—have a repertoire of voices at their command, the simplest hypothesis is that Ms. Knight
+makes “Ramtha” speak all by herself, and that she has no contact with disembodied entities from the Pleistocene
+Ice Age. If there’s evidence to the contrary, I’d love to hear it. It would be considerably more impressive if Ramtha
+could speak by himself, without the assistance of Ms. Knight’s mouth. Failing that, how might we test the claim?
+(The actress Shirley MacLaine attests that Ramtha was her brother in Atlantis, but that’s another story.)
+Suppose Ramtha were available for questioning. Could we verify whether he is who he says he is? How does
+he know that he lived 35,000 years ago, even approximately? What calendar does he employ? Who is keeping
+track of the intervening millennia? Thirty-five thousand plus or minus what? What were things like 35,000 years
+ago? Either Ramtha really is 35,000 years old, in which case we discover something about that period, or he’s a
+phony and he’ll (or rather she’ll) slip up.
+Where did Ramtha live? (I know he speaks English with an Indian accent, but where 35,000 years ago did they
+do that?) What was the climate? What did Ramtha eat? (Archaeologists know something about what people ate
+back then.) What were the indigenous languages, and social structure? Who else did Ramtha live with—wife, wives,
+children, grandchildren? What was the life cycle, the infant mortality rate, the life expectancy? Did they have birth
+control? What clothes did they wear? How were the clothes manufactured? What were the most dangerous predators? Hunting and fishing implements and strategies? Weapons? Endemic sexism? Xenophobia and ethnocentrism?
+And if Ramtha came from the “high civilization” of Atlantis, where are the linguistic, technological, historical and
+other details? What was their writing like? Tell us. Instead, all we are offered are banal homilies.
+Here, to take another example, is a set of information channeled not from an ancient dead person, but from
+unknown non-human entities who make crop circles, as recorded by the journalist Jim Schnabel:
+We are so anxious at this sinful nation spreading lies about us. We do not come in machines, we do
+not land on your earth in machines … We come like the wind. We are Life Force. Life Force from
+the ground … Come here … We are but a breath away … a breath away … we are not a million
+miles away … a Life Force that is larger than the energies in your body. But we meet at a higher
+level of life … We need no name. We are parallel to your world, alongside your world … The walls
+are broken. Two men will rise from the past … the great bear … the world will be at peace.
+People pay attention to these puerile marvels mainly because they promise something like old-time religion,
+but especially life after death, even life eternal.
+A very different prospect for something like eternal life was once proposed by the versatile British scientist
+J.B.S. Haldane, who was, among many other things, one of the founders of population genetics. Haldane
+imagined a far future when the stars have darkened and space is mainly filled with a cold, thin gas. Nevertheless,
+if we wait long enough statistical fluctuations in the density of this gas will occur. Over immense periods of time
+the fluctuations will be sufficient to reconstitute a Universe something like our own. If the Universe is infinitely
+old, there will be an infinite number of such reconstitutions, Haldane pointed out.
+So in an infinitely old universe with an infinite number of appearances of galaxies, stars, planets, and life, an
+identical Earth must reappear on which you and all your loved ones will be reunited. I’ll be able to see my parents
+again and introduce them to the grandchildren they never knew. And all this will happen not once, but an
+infinite number of times.
+Somehow, though, this does not quite offer the consolations of religion. If none of us is to have any recollection
+of what happened this time around, the time the reader and I are sharing, the satisfactions of bodily resurrection, in
+my ears at least, ring hollow.
+But in this reflection I have underestimated what infinity means. In Haldane’s picture, there will he universes,
+indeed an infinite number of them, in which our brains will have full recollection of many previous rounds.
+Satisfaction is at hand—tempered, though, by the thought of all those other universes which will also come into
+existence (again, not once but an infinite number of times) with tragedies and horrors vastly outstripping
+anything I’ve experienced this turn.
+The Consolation of Haldane depends, though, on what kind of universe we live in, and maybe on such
+arcana as whether there’s enough matter to eventually reverse the expansion of the universe, and the character of
+vacuum fluctuations. Those with a deep longing for life after death might, it seems, devote themselves to
+cosmology, quantum gravity, elementary particle physics, and transfinite arithmetic. 
+——
+Clement of Alexandria, a Father of the early Church, in his Exhortations to the Greeks (written around the year 190)
+dismissed pagan beliefs in words that might today seem a little ironic:
+Far indeed are we from allowing grown men to listen to such tales. Even to our own children, when
+they are crying their heart out, as the saying goes, we are not in the habit of telling fabulous stories
+to soothe them.
+In our time we have less severe standards. We tell children about Santa Claus, the Easter Bunny, and the
+Tooth Fairy for reasons we think emotionally sound, but then disabuse them of these myths before they’re grown.
+Why retract? Because their well-being as adults depends on them knowing the world as it really is. We worry, and
+for good reason, about adults who still believe in Santa Claus.
+On doctrinaire religions, “Men dare not avow, even to their own hearts,” wrote the philosopher David Hume,
+the doubts which they entertain on such subjects. They make a merit of implicit faith; and disguise
+to themselves their real infidelity, by the strongest asseverations and the most positive bigotry.
+This infidelity has profound moral consequences, as the American revolutionary Tom Paine wrote in The Age
+of Reason:
+Infidelity does not consist in believing, or in disbelieving; it consists in professing to believe what
+one does not believe. It is impossible to calculate the moral mischief, if I may so express it, that
+mental lying has produced in society. When man has so far corrupted and prostituted the chastity of
+his mind, as to subscribe his professional belief to things he does not believe, he has prepared
+himself for the commission of every other crime.
+T. H. Huxley’s formulation was
+The foundation of morality is to … give up pretending to believe that for which there is no evidence,
+and repeating unintelligible propositions about things beyond the possibilities of knowledge.
+Clement, Hume, Paine, and Huxley were all talking about religion. But much of what they wrote has more
+general applications—for example to the pervasive background importunings of our commercial civilization:
+There is a class of aspirin commercials in which actors pretending to be doctors reveal the competing product to
+have only so much of the painkilling ingredient that doctors recommend most—they don’t tell you what the
+mysterious ingredient is. Whereas their product has a dramatically larger amount (1.2 to 2 times more per tablet).
+So buy their product. But why not just take two of the competing tablets? Or consider the analgesic that works
+better than the “regular-strength” product of the competition. Why not then take the “extra-strength” competitive product? And of course they do not tell us of the more than a thousand deaths each year in the United States
+from the use of aspirin, or the roughly 5,000 annual cases of kidney failure from the use of acetaminophen,
+chiefly Tylenol. (This, however, may represent a case of corelation without causation.) Or who cares which breakfast cereal has more vitamins when we can take a vitamin pill with breakfast? Likewise, why should it matter
+whether an antacid contains calcium if the calcium is for nutrition and irrelevant for gastritis? Commercial
+culture is full of similar misdirections and evasions at the expense of the consumer. You’re not supposed to ask.
+Don’t think. Buy.
+Paid product endorsements, especially by real or purported experts, constitute a steady rainfall of deception.
+They betray contempt for the intelligence of their customers. They introduce an insidious corruption of popular
+attitudes about scientific objectivity. Today there are even commercials in which real scientists, some of
+considerable distinction, shill for corporations. They teach that scientists too will lie for money. As Tom Paine
+warned, inuring us to lies lays the groundwork for many other evils.
+I have in front of me as I write the program of one of the annual Whole Life Expos, New Age expositions held
+in San Francisco. Typically, tens of thousands of people attend. Highly questionable experts tout highly questionable products. Here are some of the presentations: “How Trapped Blood Proteins Produce Pain and Suffering.”
+“Crystals, Are They Talismans or Stones?” (I have an opinion myself.) It continues: “As a crystal focuses sound
+and light waves for radio and television”—this is a vapid misunderstanding of how radio and television work—
+“so may it amplify spiritual vibrations for the attuned human.” Or here’s one “Return of the Goddess, a Presentational Ritual.” Another: “Synchronicity, the Recognition Experience.” That one is given by “Brother Charles.” 
+Or, on the next page, “You, Saint-Germain, and Healing Through the Violet Flame.” It goes on and on, with
+plenty of ads about “opportunities”—running the short gamut from the dubious to the spurious—that are
+available at the Whole Life Expo.
+Distraught cancer victims make pilgrimages to the Philippines, where “psychic surgeons,” having palmed bits
+of chicken liver or goat heart, pretend to reach into the patient’s innards and withdraw the diseased tissue, which
+is then triumphantly displayed. Leaders of Western democracies regularly consult astrologers and mystics before
+making decisions of state. Under public pressure for results, police with an unsolved murder or a missing body on
+their hands consult ESP “experts” (who never guess better than expected by common sense, but the police, the
+ESPers say, keep calling). A clairvoyance gap with adversary nations is announced, and the Central Intelligence
+Agency, under Congressional prodding, spends tax money to find out whether submarines in the ocean depths
+can be located by thinking hard at them. A “psychic”—using pendulums over maps and dowsing rods in
+airplanes—purports to find new mineral deposits; an Australian mining company pays him top dollar up front,
+none of it returnable in the event of failure, and a share in the exploitation of ores in the event of success.
+Nothing is discovered. Statues of Jesus or murals of Mary are spotted with moisture, and thousands of kindhearted people convince themselves that they have witnessed a miracle.
+These are all cases of proved or presumptive baloney. A deception arises, sometimes innocently but collaboratively, sometimes with cynical premeditation. Usually the victim is caught up in a powerful emotion—wonder,
+fear, greed, grief. Credulous acceptance of baloney can cost you money; that’s what P. T. Barnum meant when he
+said, “There’s a sucker born every minute.” But it can be much more dangerous than that, and when governments and societies lose the capacity for critical thinking, the results can be catastrophic—however sympathetic
+we may be to those who have bought the baloney.
+In science we may start with experimental results, data, observations, measurements, “facts.” We invent, if we
+can, a rich array of possible explanations and systematically confront each explanation with the facts. In the
+course of their training, scientists are equipped with a baloney detection kit. The kit is brought out as a matter of
+course whenever new ideas are offered for consideration. If the new idea survives examination by the tools in our
+kit, we grant it warm, although tentative, acceptance. If you’re so inclined, if you don’t want to buy baloney even
+when it’s reassuring to do so, there are precautions that can be taken; there’s a tried-and-true, consumer-tested
+method.
+What’s in the kit? Tools for skeptical thinking.
+What skeptical thinking boils down to is the means to construct, and to understand, a reasoned argument
+and—especially important—to recognize a fallacious or fraudulent argument. The question is not whether we
+like the conclusion that emerges out of a train of reasoning, but whether the conclusion follows from the premise
+or starting point and whether that premise is true.
+Among the tools:
+· Wherever possible there must be independent confirmation of the “facts.”
+· Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.
+· Arguments from authority carry little weight—“authorities” have made mistakes in the past. They will do
+so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there
+are experts.
+· Spin more than one hypothesis. If there’s something to be explained, think of all the different ways in
+which it could be explained. Then think of tests by which you might systematically disprove each of the
+alternatives. What survives, the hypothesis that resists disproof in this Darwinian selection among
+“multiple working hypotheses,” has a much better chance of being the right answer than if you had simply
+run with the first idea that caught your fancy.*
+· Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of
+knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find
+reasons for rejecting it. If you don’t, others will.
+* This is a problem that affects jury trials. Retrospective studies show that some jurors make up their minds very early—
+perhaps during opening arguments—and then retain the evidence that seems to support their initial impressions and reject
+the contrary evidence. The method of alternative working hypotheses is not running in their heads. 
+· Quantify. If whatever it is you’re explaining has some measure, some numerical quantity attached to it,
+you’ll be much better able to discriminate among competing hypotheses. What is vague and qualitative is
+open to many explanations. Of course there are truths to be sought in the many qualitative issues we are
+obliged to confront, but finding them is more challenging.
+· If there’s a chain of argument, every link in the chain must work (including the premise)—not just most of
+them.
+· Occam’s Razor. This convenient rule-of-thumb urges us when faced with two hypotheses that explain the
+data equally well to choose the simpler.
+· Always ask whether the hypothesis can be, at least in principle, falsified. Propositions that are untestable,
+unfalsifiable, are not worth much. Consider the grand idea that our Universe and everything in it is just an
+elementary particle—an electron, say—in a much bigger Cosmos. But if we can never acquire information
+from outside our Universe, is not the idea incapable of disproof? You must be able to check assertions out.
+Inveterate skeptics must be given the chance to follow your reasoning, to duplicate your experiments and
+see if they get the same result.
+The reliance on carefully designed and controlled experiments is key, as I tried to stress earlier. We will not
+learn much from mere contemplation. It is tempting to rest content with the first candidate explanation we can
+think of. One is much better than none. But what happens if we can invent several? How do we decide among
+them? We don’t. We let experiment do it. Francis Bacon provided the classic reason:
+Argumentation cannot suffice for the discovery of new work, since the subtlety of Nature is greater
+many times than the subtlety of argument.
+Control experiments are essential. If, for example, a new medicine is alleged to cure a disease 20 percent of the
+time, we must make sure that a control population, taking a dummy sugar pill which as far as the subjects know
+might be the new drug, does not also experience spontaneous remission of the disease 20 percent of the time.
+Variables must be separated. Suppose you’re seasick, and given both an acupressure bracelet and 50 milligrams
+of meclizine. You find the unpleasantness vanishes. What did it—the bracelet or the pill? You can tell only if you
+take the one without the other, next time you’re seasick. Now imagine that you’re not so dedicated to science as to
+be willing to be seasick. Then you won’t separate the variables. You’ll take both remedies again. You’ve achieved
+the desired practical result; further knowledge, you might say, is not worth the discomfort of attaining it.
+Often the experiment must be done “double-blind,” so that those hoping for a certain finding are not in the
+potentially compromising position of evaluating the results. In testing a new medicine, for example, you might
+want the physicians who determine which patients’ symptoms are relieved not to know which patients have been
+given the new drug. The knowledge might influence their decision, even if only unconsciously. Instead the list of
+those who experienced remission of symptoms can be compared with the list of those who got the new drug, each
+independently ascertained. Then you can determine what correlation exists. Or in conducting a police lineup or
+photo identification, the officer in charge should not know who the prime suspect is, so as not consciously or
+unconsciously to influence the witness.
+——
+In addition to teaching us what to do when evaluating a claim to knowledge, any good baloney detection kit
+must also teach us what not to do. It helps us recognize the most common and perilous fallacies of logic and
+rhetoric. Many good examples can be found in religion and politics, because their practitioners are so often obliged
+to justify two contradictory propositions. Among these fallacies are:
+· ad hominem—Latin for “to the man,” attacking the arguer and not the argument (e.g., The Reverend Dr.
+Smith is a known Biblical fundamentalist, so her objections to evolution need not be taken seriously);
+· argument from authority (e.g., President Richard Nixon should be re-elected because he has a secret plan to end
+the war in Southeast Asia—but because it was secret, there was no way for the electorate to evaluate it on its
+merits; the argument amounted to trusting him because he was President: a mistake, as it turned out);
+* A more cynical formulation by the Roman historian Polybius: Since the masses of the people are inconstant, full of unruly
+desires, passionate, and reckless of consequences, they must be filled with fears to keep them in order. The ancients did well,
+therefore, to invent gods, and the belief in punishment after death.
+· argument from adverse consequences (e.g., A God meting out punishment and reward must exist, because if
+He didn’t, society would be much more lawless and dangerous—perhaps even ungovernable.* Or: The defendant
+in a widely publicized murder trial must be found guilty; otherwise, it will be an encouragement for other men
+to murder their wives);
+· appeal to ignorance—the claim that whatever has not been proved false must be true, and vice versa (e.g.,
+There is no compelling evidence that UFOs are not visiting the Earth; therefore UFOs exist—and there is
+intelligent life elsewhere in the Universe. Or: There may be seventy kazillion other worlds, but not one is known
+to have the moral advancement of the Earth, so we’re still central to the Universe.) This impatience with ambiguity can be criticized in the phrase: absence of evidence is not evidence of absence.
+· special pleading, often to rescue a proposition in deep rhetorical trouble (e.g., How can a merciful God
+condemn future generations to torment because, against orders, one woman induced one man to eat an apple?
+Special plead: you don’t understand the subtle Doctrine of Free Will. Or: How can there be an equally godlike
+Father, Son, and Holy Ghost in the same Person? Special plead: You don’t understand the Divine Mystery of the
+Trinity. Or: How could God permit the followers of Judaism, Christianity, and Islam—each in their own way
+enjoined to heroic measures of loving kindness and compassion—to have perpetrated so much cruelty for so long?
+Special plead: You don’t understand Free Will again. And anyway, God moves in mysterious ways.)
+· begging the question, also called assuming the answer (e.g., We must institute the death penalty to discourage
+violent crime. But does the violent crime rate in fact fall when the death penalty is imposed? Or: The stock
+market fell yesterday because of a technical adjustment and profit-taking by investors—but is there any
+independent evidence for the causal role of “adjustment” and profit-taking; have we learned anything at all
+from this purported explanation?);
+· observational selection, also called the enumeration of favorable circumstances, or as the philosopher
+Francis Bacon described it, counting the hits and forgetting the misses* (e.g., A state boasts of the Presidents
+it has produced, but is silent on its serial killers);
+· statistics of small numbers—a close relative of observational selection (e.g., “They say 1 out of every 5 people
+is Chinese. How is this possible? I know hundreds of people, and none of them is Chinese. Yours truly.” Or: “I’ve
+thrown three sevens in a row. Tonight I can’t lose.”);
+· misunderstanding of the nature of statistics (e.g., President Dwight Eisenhower expressing astonishment
+and alarm on discovering that fully half of all Americans have below average intelligence);
+· inconsistency (e.g., Prudently plan for the worst of which a potential military adversary is capable, but thriftily
+ignore scientific projections on environmental dangers because they’re not “proved.” Or: Attribute the declining
+life expectancy in the former Soviet Union to the failures of communism many years ago, but never attribute the
+high infant mortality rate in the United States (now highest of the major industrial nations) to the failures of
+capitalism. Or: Consider it reasonable for the Universe to continue to exist forever into the future, but judge
+absurd the possibility that it has infinite duration into the past);
+· non sequitur—Latin for “It doesn’t follow” (e.g., Our nation will prevail because God is great. But nearly
+every nation pretends this to be true; the German formulation was “Gott mit uns”). Often those falling into
+the non sequitur fallacy have simply failed to recognize alternative possibilities;
+· post hoc, ergo propter hoc—Latin for “It happened after, so it was caused by” (e.g., Jaime Cardinal Sin,
+Archbishop of Manila: “I know of … a 26-year-old who looks 60 because she takes [contraceptive] pills.” Or:
+Before women got the vote, there were no nuclear weapons);
+* My favorite example is this story, told about the Italian physicist Enrico Fermi, newly arrived on American shores, enlisted
+in the Manhattan nuclear weapons Project, and brought face-to-face in the midst of World War II with U.S. flag officers.
+So-and-so is a great general, he was told. What is the definition of a great general? Fermi characteristically
+asked. I guess it’s a general who’s won many consecutive battles. How many? After some back and forth, they
+settled on five. What fraction of American generals are great? After some more back and forth, they settled on
+a few percent.
+But imagine, Fermi rejoined, that there is no such thing as a great general, that all armies are equally matched, and that
+winning a battle is purely a matter of chance. Then the chance of winning one battle is one out of two, or 1/2, two battles
+l/4, three l/8, four l/16, and five consecutive battles 1/32—which is about 3 percent. You would expect a few percent of
+American generals to win five consecutive battles—purely by chance. Now, has any of them won ten consecutive battles…?
+· excluded middle, or false dichotomy—considering only the two extremes in a continuum of intermediate
+possibilities (e.g., “Sure, take his side; my husband’s perfect; I’m always wrong.” Or: “Either you love your
+country or you hate it.” Or: “If you’re not part of the solution, you’re part of the problem”);
+· short-term vs. long-term—a subset of the excluded middle, but so important I’ve pulled it out for special
+attention (e.g., We can’t afford programs to feed malnourished children and educate pre-school kids. We need to
+urgently deal with crime on the streets. Or: Why explore space or pursue fundamental science when we have so
+huge a budget deficit?);
+· slippery slope, related to excluded middle (e.g., If we allow abortion in the first weeks of pregnancy, it will be
+impossible to prevent the killing of a full-term infant. Or, conversely: If the state prohibits abortion even in the
+ninth month, it will soon be telling us what to do with our bodies around the time of conception);
+· confusion of correlation and causation (e.g., A survey shows that more college graduates are homosexual than
+those with lesser education; therefore education makes people gay. Or: Andean earthquakes are correlated with
+closest approaches of the planet Uranus; therefore—despite the absence of any such correlation for the nearer,
+more massive planet Jupiter—the latter causes the former*);
+· straw man—caricaturing a position to make it easier to attack (e.g., Scientists suppose that living things
+simply fell together by chance—a formulation that willfully ignores the central Darwinian insight that
+Nature ratchets up by saving what works and discarding what doesn’t. Or—this is also a short-term/longterm fallacy—environmentalists care more for snail darters and spotted owls than they do for people);
+· suppressed evidence, or half-truths (e.g., An amazingly accurate and widely quoted “prophecy” of the
+assassination attempt on President Reagan is shown on television; but—an important detail—was it recorded
+before or after the event? Or: These government abuses demand revolution, even if you can’t make an omelette
+without breaking some eggs. Yes, but is this likely to be a revolution in which far more people are killed than
+under the previous regime? What does the experience of other revolutions suggest? Are all revolutions
+against oppressive regimes desirable and in the interests of the people?);
+· weasel words (e.g., The separation of powers of the U.S. Constitution specifies that the United States may
+not conduct a war without a declaration by Congress. On the other hand, Presidents are given control of
+foreign policy and the conduct of wars, which are potentially powerful tools for getting themselves reelected. Presidents of either political party may therefore be tempted to arrange wars while waving the flag
+and calling the wars something else—“police actions,” “armed incursions,” “protective reaction strikes,”
+“pacification,” “safeguarding American interests,” and a wide variety of “operations,” such as “Operation
+Just Cause.” Euphemisms for war are one of a broad class of reinventions of language for political purposes. Talleyrand said, “An important art of politicians is to find new names for institutions which under
+old names have become odious to the public”).
+Knowing the existence of such logical and rhetorical fallacies rounds out our toolkit. Like all tools, the
+baloney detection kit can be misused, applied out of context, or even employed as a rote alternative to thinking.
+But applied judiciously, it can make all the difference in the world—not least in evaluating our own arguments
+before we present them to others.
+——
+The American tobacco industry grosses some $50 billion per year. There is a statistical correlation between
+smoking and cancer, the tobacco industry admits, but not, they say, a causal relation. A logical fallacy, they imply,
+is being committed. What might this mean? Maybe people with hereditary propensities for cancer also have
+hereditary propensities to take addictive drugs - so cancer and smoking might be correlated, but the cancer would
+not be caused by the smoking. Increasingly farfetched connections of this sort can be contrived. This is exactly
+one of the reasons science insists on control experiments.
+* Children who watch violent TV programs tend to be more violent when they grow up. But did the TV cause the violence,
+or do violent children preferentially enjoy watching violent programs? Very likely both are true. Commercial defenders of TV
+violence argue that anyone can distinguish between television and reality. But Saturday morning children’s programs now
+average 25 acts of violence per hour. At the very least this desensitizes young children to aggression and random cruelty. And
+if impressionable adults can have false memories implanted in their brains, what are we implanting in our children when we
+expose them to some 100,000 acts of violence before they graduate from elementary school?
+Suppose you paint the backs of large numbers of mice with cigarette tar, and also follow the health of large
+numbers of nearly identical mice that have not been painted. If the former get cancer and the latter do not, you
+can be pretty sure that the correlation is causal. Inhale tobacco smoke, and the chance of getting cancer goes up;
+don’t inhale, and the rate stays at the background level. Likewise for emphysema, bronchitis, and cardiovascular
+diseases.
+When the first work was published in the scientific literature in 1953 showing that the substances in cigarette
+smoke when painted on the backs of rodents produce malignancies, the response of the six major tobacco
+companies was to initiate a public relations campaign to impugn the research, sponsored by the Sloan Kettering
+Foundation. This is similar to what the Du Pont Corporation did when the first research was published in 1974
+showing that their Freon product attacks the protective ozone layer. There are many other examples.
+You might think that before they denounce unwelcome research findings, major corporations would devote
+their considerable resources to checking out the safety of the products they propose to manufacture. And if they
+missed something, if independent scientists suggest a hazard, why would the companies protests? Would they
+rather kill people than lose profits? If, in an uncertain world, an error must be made, shouldn’t it be biasing
+toward protecting customers and the public?
+A 1971 internal report of the Brown and Williamson tobacco Corporation lists as a corporate objective “to set
+aside in the minds of millions the false conviction that cigarette smoking causes lung cancer and other diseases; a
+conviction based on fanatical assumptions, fallacious rumors, unsupported claims and the unscientific statements
+and conjectures of publicity-seeking opportunists.” They complain of
+the incredible, unprecedented and nefarious attack against the cigarette, constituting the greatest
+libel and slander ever perpetrated against any product in the history of free enterprise; a criminal
+libel of such major proportions and implications that one wonders how such a crusade of calumny
+can be reconciled under the Constitution can be so flouted and violated [sic].
+This rhetoric is only slightly more inflamed than what the tobacco industry has from time to time uttered for
+public consumption.
+There are many brands of cigarettes that advertise low “tar” (ten milligrams or less per cigarette). Why is this a
+virtue? Because it is the refractory tars in which the polycyclic aromatic hydrocarbons and some other carcinogens
+are concentrated. Aren’t the low-tar ads a tacit admission by the tobacco companies that cigarettes indeed cause
+cancer?
+Healthy Buildings International is a for-profit organization, recipient of millions of dollars over the years from
+the tobacco industry. It performs research on second-hand smoke, and testifies for the tobacco companies. In
+1994, three of its technicians complained that senior executives had faked data on inhalable cigarette particles in
+the air. In every case, the invented or “corrected” data made tobacco smoke seem safer than the technicians’
+measurements had indicated. Do corporate research departments or outside research contractors ever find a
+product to be more dangerous than the tobacco corporation has publicly declared? If they do, is their employment continued?
+Tobacco is addictive; by many criteria more so than heroin and cocaine. There was a reason people would, as
+the 1940s ad put it, “walk a mile for a Camel.” More people have died of tobacco than in all of World War II.
+According to the World Health Organization, smoking kills three million people every year worldwide. This will
+rise to ten million annual deaths by 2020—in part because of a massive advertising campaign to portray smoking
+as advanced and fashionable to young women in the developing world. Part of the success of the tobacco industry
+in purveying this brew of addictive poisons can be attributed to widespread unfamiliarity with baloney detection,
+critical thinking, and the scientific method. Gullibility kills.

+The Last Question
+By Isaac Asimov
+
+     Isaac Asimov was the most prolific science fiction author of all time. In fifty years he averaged a new magazine article, short story, or book every two weeks, and most of that on a manual typewriter. Asimov thought that The Last Question, first copyrighted in 1956, was his best short story ever. Even if you do not have the background in science to be familiar with all of the concepts presented here, the ending packs more impact than any other book that I've ever read. Don't read the end of the story first!
+This is by far my favorite story of all those I have written.
+     After all, I undertook to tell several trillion years of human history in the space of a short story and I leave it to you as to how well I succeeded. I also undertook another task, but I won't tell you what that was lest l spoil the story for you.
+     It is a curious fact that innumerable readers have asked me if I wrote this story. They seem never to remember the title of the story or (for sure) the author, except for the vague thought it might be me. But, of course, they never forget the story itself especially the ending. The idea seems to drown out everything -- and I'm satisfied that it should.
+     The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five-dollar bet over highballs, and it happened this way:
+     Alexander Adell and Bertram Lupov were two of the faithful attendants of Multivac. As well as any human beings could, they knew what lay behind the cold, clicking, flashing face -- miles and miles of face -- of that giant computer. They had at least a vague notion of the general plan of relays and circuits that had long since grown past the point where any single human could possibly have a firm grasp of the whole.
+     Multivac was self-adjusting and self-correcting. It had to be, for nothing human could adjust and correct it quickly enough or even adequately enough. So Adell and Lupov attended the monstrous giant only lightly and superficially, yet as well as any men could. They fed it data, adjusted questions to its needs and translated the answers that were issued. Certainly they, and all others like them, were fully entitled to share in the glory that was Multivac's.
+     For decades, Multivac had helped design the ships and plot the trajectories that enabled man to reach the Moon, Mars, and Venus, but past that, Earth's poor resources could not support the ships. Too much energy was needed for the long trips. Earth exploited its coal and uranium with increasing efficiency, but there was only so much of both.
+     But slowly Multivac learned enough to answer deeper questions more fundamentally, and on May 14, 2061, what had been theory, became fact.
+     The energy of the sun was stored, converted, and utilized directly on a planet-wide scale. All Earth turned off its burning coal, its fissioning uranium, and flipped the switch that connected all of it to a small station, one mile in diameter, circling the Earth at half the distance of the Moon. All Earth ran by invisible beams of sunpower.
+     Seven days had not sufficed to dim the glory of it and Adell and Lupov finally managed to escape from the public functions, and to meet in quiet where no one would think of looking for them, in the deserted underground chambers, where portions of the mighty buried body of Multivac showed. Unattended, idling, sorting data with contented lazy clickings, Multivac, too, had earned its vacation and the boys appreciated that. They had no intention, originally, of disturbing it.
+     They had brought a bottle with them, and their only concern at the moment was to relax in the company of each other and the bottle.
+     "It's amazing when you think of it," said Adell. His broad face had lines of weariness in it, and he stirred his drink slowly with a glass rod, watching the cubes of ice slur clumsily about. "All the energy we can possibly ever use for free. Enough energy, if we wanted to draw on it, to melt all Earth into a big drop of impure liquid iron, and still never miss the energy so used. All the energy we could ever use, forever and forever and forever."
+     Lupov cocked his head sideways. He had a trick of doing that when he wanted to be contrary, and he wanted to be contrary now, partly because he had had to carry the ice and glassware. "Not forever," he said.
+     "Oh, hell, just about forever. Till the sun runs down, Bert."
+     "That's not forever."
+     "All right, then. Billions and billions of years. Ten billion, maybe. Are you satisfied?"
+     Lupov put his fingers through his thinning hair as though to reassure himself that some was still left and sipped gently at his own drink. "Ten billion years isn't forever."
+     "Well, it will last our time, won't it?"
+     "So would the coal and uranium."
+     "All right, but now we can hook up each individual spaceship to the Solar Station, and it can go to Pluto and back a million times without ever worrying about fuel. You can't do that on coal and uranium. Ask Multivac, if you don't believe me.
+     "I don't have to ask Multivac. I know that."
+     "Then stop running down what Multivac's done for us," said Adell, blazing up, "It did all right."
+     "Who says it didn't? What I say is that a sun won't last forever. That's all I'm saying. We're safe for ten billion years, but then what?" Lupow pointed a slightly shaky finger at the other. "And don't say we'll switch to another sun."
+     There was silence for a while. Adell put his glass to his lips only occasionally, and Lupov's eyes slowly closed. They rested.
+     Then Lupov's eyes snapped open. "You're thinking we'll switch to another sun when ours is done, aren't you?"
+     "I'm not thinking."
+     "Sure you are. You're weak on logic, that's the trouble with you. You're like the guy in the story who was caught in a sudden shower and who ran to a grove of trees and got under one. He wasn't worried, you see, because he figured when one tree got wet through, he would just get under another one."
+     "I get it," said Adell. "Don't shout. When the sun is done, the other stars will be gone, too."
+     "Darn right they will," muttered Lupov. "It all had a beginning in the original cosmic explosion, whatever that was, and it'll all have an end when all the stars run down. Some run down faster than others. Hell, the giants won't last a hundred million years. The sun will last ten billion years and maybe the dwarfs will last two hundred billion for all the good they are. But just give us a trillion years and everything will be dark. Entropy has to increase to maximum, that's all."
+     "I know all about entropy," said Adell, standing on his dignity.
+     "The hell you do."
+     "I know as much as you do."
+     "Then you know everything's got to run down someday."
+     "All right. Who says they won't?"
+     "You did, you poor sap. You said we had all the energy we needed, forever. You said 'forever.'
+     It was Adell's turn to be contrary. "Maybe we can build things up again someday," he said.
+     "Never."
+     "Why not? Someday."
+     "Never."
+     "Ask Multivac."
+     "You ask Multivac. I dare you. Five dollars says it can't be done."
+     Adell was just drunk enough to try, just sober enough to be able to phrase the necessary symbols and operations into a question which, in words, might have corresponded to this: Will mankind one day without the net expenditure of energy be able to restore the sun to its full youthfulness even after it had died of old age?
+     Or maybe it could be put more simply like this: How can the net amount of entropy of the universe be massively decreased?
+     Multivac fell dead and silent. The slow flashing of lights ceased, the distant sounds of clicking relays ended.
+     Then, just as the frightened technicians felt they could hold their breath no longer, there was a sudden springing to life of the teletype attached to that portion of Multivac. Five words were printed: INSUFFICIENT DATA FOR MEANINGFUL ANSWER.
+     "No bet," whispered Lupov. They left hurriedly.
+     By next morning, the two, plagued with throbbing head and cottony mouth, had forgotten the incident.
+     Jerrodd, Jerrodine, and Jerrodette I and II watched the starry picture in the visiplate change as the passage through hyperspace was completed in its non-time lapse. At once, the even powdering of stars gave way to the predominance of a single bright shining disk, the size of a marble, centered on the viewing-screen.
+     "That's X-23," said Jerrodd confidently. His thin hands clamped tightly behind his back and the knuckles whitened.
+     The little Jerrodettes, both girls, had experienced the hyperspace passage for the first time in their lives and were self-conscious over the momentary sensation of insideoutness. They buried their giggles and chased one another wildly about their mother, screaming, "We've reached X-23 -- we've reached X-23 -- we've --"
+     "Quiet, children." said Jerrodine sharply. "Are you sure, Jerrodd?"
+     "What is there to be but sure?" asked Jerrodd, glancing up at the bulge of featureless metal just under the ceiling. It ran the length of the room, disappearing through the wall at either end. It was as long as the ship.
+     Jerrodd scarcely knew a thing about the thick rod of metal except that it was called a Microvac, that one asked it questions if one wished; that if one did not it still had its task of guiding the ship to a preordered destination; of feeding on energies from the various Sub-galactic Power Stations; of computing the equations for the hyperspatial jumps.
+     Jerrodd and his family had only to wait and live in the comfortable residence quarters of the ship. Someone had once told Jerrodd that the "ac" at the end of "Microvac" stood for ''automatic computer" in ancient English, but he was on the edge of forgetting even that.
+     Jerrodine's eyes were moist as she watched the visiplate. "I can't help it. I feel funny about leaving Earth."
+     "Why, for Pete's sake?" demanded Jerrodd. "We had nothing there. We'll have everything on X-23. You won't be alone. You won't be a pioneer. There are over a million people on the planet already. Good Lord, our great-grandchildren will be looking for new worlds because X-23 will be overcrowded." Then, after a reflective pause, "I tell you, it's a lucky thing the computers worked out interstellar travel the way the race is growing."
+     "I know, I know," said Jerrodine miserably.
+     Jerrodette I said promptly, "Our Microvac is the best Microvac in the world."
+     "I think so, too," said Jerrodd, tousling her hair.
+     It was a nice feeling to have a Microvac of your own and Jerrodd was glad he was part of his generation and no other. In his father's youth, the only computers had been tremendous machines taking up a hundred square miles of land. There was only one to a planet. Planetary ACs they were called. They had been growing in size steadily for a thousand years and then, all at once, came refinement. In place of transistors, had come molecular valves so that even the largest Planetary AC could be put into a space only half the volume of a spaceship.
+     Jerrodd felt uplifted, as he always did when he thought that his own personal Microvac was many times more complicated than the ancient and primitive Multivac that had first tamed the Sun, and almost as complicated as Earth's Planetarv AC (the largest) that had first solved the problem of hyperspatial travel and had made trips to the stars possible.
+     "So many stars, so many planets," sighed Jerrodine, busy with her own thoughts. "I suppose families will be going out to new planets forever, the way we are now."
+     "Not forever," said Jerrodd, with a smile. "It will all stop someday, but not for billions of years. Many billions. Even the stars run down, you know. Entropy must increase.
+     "What's entropy, daddy?" shrilled Jerrodette II.
+     "Entropy, little sweet, is just a word which means the amount of running-down of the universe. Everything runs down, you know, like your little walkie-talkie robot, remember?"
+     "Can't you just put in a new power-unit, like with my robot?"
+     "The stars are the power-units. dear. Once they're gone, there are no more power-units."
+     Jerrodette I at once set up a howl. "Don't let them, daddy. Don't let the stars run down."
+     "Now look what you've done," whispered Jerrodine, exasperated.
+     "How was I to know it would frighten them?" Jerrodd whispered back,
+     "Ask the Microvac," wailed Jerrodette I. "Ask him how to turn the stars on again."
+     "Go ahead," said Jerrodine. "It will quiet them down." (Jerrodette II was beginning to cry, also.)
+     Jerrodd shrugged. "Now, now, honeys. I'll ask Microvac. Don't worry, he'll tell us."
+     He asked the Microvac, adding quickly, "Print the answer."
+     Jerrodd cupped the strip or thin cellufilm and said cheerfully, "See now, the Microvac says it will take care of everything when the time comes so don't worry."
+     Jerrodine said, "And now, children, it's time for bed. We'll be in our new home soon."
+     Jerrodd read the words on the cellufilm again before destroying it: INSUFICIENT DATA FOR MEANINGFUL ANSWER.
+     He shrugged and looked at the visiplate. X-23 was just ahead.
+     VJ-23X of Lameth stared into the black depths of the three-dimensional, small-scale map of the Galaxy and said, "Are we ridiculous, I wonder in being so concerned about the matter?"
+     MQ-17J of Nicron shook his head. "I think not. You know the Galaxy will be filled in five years at the present rate of expansion."
+     Both seemed in their early twenties, both were tall and perfectly formed.
+     "Still," said VJ-23X, "I hesitate to submit a pessimistic report to the Galactic Council."
+     "I wouldn't consider any other kind of report. Stir them up a bit. We've got to stir them up."
+     VJ-23X sighed. "Space is infinite. A hundred billion Galaxies are there for the taking. More."
+     "A hundred billion is not infinite and it's getting less infinite all the time. Consider! Twenty thousand years ago, mankind first solved the problem of utilizing stellar energy, and a few centuries later, interstellar travel became possible. It took mankind a million years to fill one small world and then only fifteen thousand years to fill the rest of the Galaxy. Now the population doubles every ten years --
+     VJ-23X interrupted. "We can thank immortality for that."
+     "Very well. Immortality exists and we have to take it into account. I admit it has its seamy side, this immortality. The Galactic AC has solved many problems for us, but in solving the problem of preventing old age and death, it has undone all its other solutions."
+     "Yet you wouldn't want to abandon life, I suppose."
+     "Not at all," snapped MQ-17J, softening it at once to, "Not yet. I'm by no means old enough. How old are you?"
+     "Two hundred twenty-three. And you?"
+     "I'm still under two hundred. --But to get back to my point. Population doubles every ten years. Once this GaIaxy is filled, we'll have filled another in ten years. Another ten years and we'll have filled two more. Another decade, four more. In a hundred years, we'll have filled a thousand Galaxies. In a thousand years, a million Galaxies. In ten thousand years, the entire known universe. Then what?"
+     VJ-23X said, "As a side issue, there's a problem of transportation. I wonder how many sunpower units it will take to move Galaxies of individuals from one Galaxy to the next."
+     "A very good point. Already, mankind consumes two sunpower units per year."
+     "Most of it's wasted. After all, our own Galaxy alone pours out a thousand sunpower units a year and we only use two of those."
+     "Granted, but even with a hundred per cent efficiency, we only stave off the end. Our energy requirements are going up in a geometric progression even faster than our population. We'll run out of energy even sooner than we run out of Galaxies. A good point. A very good point."
+     "We'll just have to build new stars out of interstellar gas."
+     "Or out of dissipated heat?" asked MQ-17J, sarcastically.
+     "There may be some way to reverse entropy. We ought to ask the Galactic AC."
+     VJ-23X was not really serious, but MQ-17J pulled out his AC-contact from his pocket and placed it on the table before him.
+     "I've half a mind to," he said. "It's something the human race will have to face someday."
+     He stared somberly at his small AC-contact. It was only two inches cubed and nothing in itself, but it was connected through hyperspace with the great Galactic AC that served all mankind. Hyperspace considered, it was an integral part of the Galactic AC.
+     MQ-17J paused to wonder if someday in his immortal life he would get to see the Galactic AC. It was on a little world of its own, a spider webbing of force-beams holding the matter within which surges of submesons took the place of the old clumsy molecular valves. Yet despite its sub-etheric workings, the Galactic AC was known to be a full thousand feet across.
+     MQ-17J asked suddenly of his AC-contact, "Can entropy ever be reversed?"
+     VJ-23X looked startled and said at once, "Oh, say, I didn't really mean to have you ask that."
+     "Why not?"
+     "We both know entropy can't be reversed. You can't turn smoke and ash back into a tree."
+     "Do you have trees on your world?" asked MQ-17J.
+     The sound of the Galactic AC startled them into silence. Its voice came thin and beautiful out of the small AC-contact on the desk. It said: THERE IS INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.
+     VJ-23X said, "See!"
+     The two men thereupon returned to the question of the report they were to make to the Galactic Council.
+     Zee Prime's mind spanned the new Galaxy with a faint interest in the countless twists of stars that powdered it. He had never seen this one before. Would he ever see them all? So many of them, each with its load of humanity. --But a load that was almost a dead weight. More and more, the real essence of men was to be found out here, in space.
+     Minds, not bodies! The immortal bodies remained back on the planets, in suspension over the eons. Sometimes they roused for material activity but that was growing rarer. Few new individuals were coming into existence to join the incredibly mighty throng, but what matter? There was little room in the Universe for new individuals.
+     Zee Prime was roused out of his reverie upon coming across the wispy tendrils of another mind.
+     "I am Zee Prime," said Zee Prime. "And you?"
+     "I am Dee Sub Wun. Your Galaxy?"
+     "We call it only the Galaxy. And you?"
+     "We call ours the same. All men call their Galaxy their Galaxy and nothing more. Why not?"
+     "True. Since all Galaxies are the same."
+     "Not all Galaxies. On one particular Galaxy the race of man must have originated. That makes it different."
+     Zee Prime said, "On which one?"
+     "I cannot say. The Universal AC would know."
+     "Shall we ask him? I am suddenly curious."
+     Zee Prime's perceptions broadened until the Galaxies themselves shrank and became a new, more diffuse powdering on a much larger background. So many hundreds of billions of them, all with their immortal beings, all carrying their load of intelligences with minds that drifted freely through space. And yet one of them was unique among them all in being the original Galaxy. One of them had, in its vague and distant past, a period when it was the only Galaxy populated by man.
+     Zee Prime was consumed with curiosity to see this Galaxy and he called out: "Universal AC! On which Galaxy did mankind originate?"
+     The Universal AC heard, for on every world and throughout space, it had its receptors ready, and each receptor led through hyperspace to some unknown point where the Universal AC kept itself aloof.
+     Zee Prime knew of only one man whose thoughts had penetrated within sensing distance of Universal AC, and he reported only a shining globe, two feet across, difficult to see.
+     "But how can that be all of Universal AC?" Zee Prime had asked.
+     "Most of it," had been the answer, "is in hyperspace. In what form it is there I cannot imagine."
+     Nor could anyone, for the day had long since passed, Zee Prime knew, when any man had any part of the making of a Universal AC. Each Universal AC designed and constructed its successor. Each, during its existence of a million years or more accumulated the necessary data to build a better and more intricate, more capable successor in which its own store of data and individuality would be submerged.
+     The Universal AC interrupted Zee Prime's wandering thoughts, not with words, but with guidance. Zee Prime's mentality was guided into the dim sea of Galaxies and one in particular enlarged into stars.
+     A thought came, infinitely distant, but infinitely clear. "THIS IS THE ORIGINAL GALAXY OF MAN."
+     But it was the same after all, the same as any other, and Lee Prime stifled his disappointment.
+     Dee Sub Wun, whose mind had accompanied the other, said suddenly, "And is one of these stars the original star of Man?"
+     The Universal AC said, "MAN'S ORIGINAL STAR HAS GONE NOVA. IT IS A WHITE DWARF"
+     "Did the men upon it die?" asked Lee Prime, startled and without thinking.
+     The Universal AC said, "A NEW WORLD, AS IN SUCH CASES WAS CONSTRUCTED FOR THEIR PHYSICAL BODIES IN TlME."
+     "Yes, of course," said Zee Prime, but a sense of loss overwhelmed him even so. His mind released its hold on the original Galaxy of Man, let it spring back and lose itself among the blurred pin points. He never wanted to see it again.
+     Dee Sub Wun said, "What is wrong?"
+     "The stars are dying. The original star is dead."
+     "They must all die. Why not?"
+     "But when all energy is gone, our bodies will finally die, and you and I with them."
+     "It will take billions of years."
+     "I do not wish it to happen even after billions of years. Universal AC! How may stars be kept from dying?"
+     Dee Sub Wun said in amusement, "You're asking how entropy might be reversed in direction."
+     And the Universal AC answered: "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
+     Zee Prime's thoughts fled back to his own Galaxy. He gave no further thought to Dee Sub Wun, whose body might be waiting on a Galaxy a trillion light-years away, or on the star next to Zee Prime's own. It didn't matter.
+     Unhappily, Zee Prime began collecting interstellar hydrogen out of which to build a small star of his own. If the stars must someday die, at least some could yet be built.
+     Man considered with himself, for in a way, Man, mentally, was one. He consisted of a trillion, trillion, trillion ageless bodies, each in its place, each resting quiet and incorruptible, each cared for by perfect automatons, equally incorruptible, while the minds of all the bodies freely melted one into the other, indistinguishable.
+     Man said, "The Universe is dying."
+     Man looked about at the dimming Galaxies. The giant stars, spendthrifts, were gone long ago, back in the dimmest of the dim far past. Almost all stars were white dwarfs, fading to the end.
+     New stars had been built of the dust between the stars, some by natural processes, some by Man himself, and those were going, too. White dwarfs might yet be crashed together and of the mighty forces so released, new stars built, but only one star for every thousand white dwarfs destroyed, and those would come to an end, too.
+     Man said, "Carefully husbanded, as directed by the Cosmic AC, the energy that is even yet left in all the Universe will last for billions of years."
+     "But even so," said Man, "eventually it will all come to an end. However it may be husbanded, however stretched out, the energy once expended is gone and cannot be restored. Entropy must increase forever to the maximum."
+     Man said, "Can entropy not be reversed? Let us ask the Cosmic AC."
+     The Cosmic AC surrounded them but not in space. Not a fragment of it was in space. It was in hyperspace and made of something that was neither matter nor energy. The question of its size and nature no longer had meaning in any terms that Man could comprehend.
+     "Cosmic AC," said Man, "how may entropy be reversed?"
+     The Cosmic AC said, "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
+     Man said, "Collect additional data."
+     The Cosmic AC said, 'I WILL DO S0. I HAVE BEEN DOING SO FOR A HUNDRED BILLION YEARS. MY PREDECESORS AND I HAVE BEEN ASKED THIS QUESTION MANY TlMES. ALL THE DATA I HAVE REMAINS INSUFFICIENT.
+     "Will there come a time," said Man, 'when data will be sufficient or is the problem insoluble in all conceivable circumstances?"
+     The Cosmic AC said, "NO PROBLEM IS INSOLUBLE IN ALL CONCEIVABLE CIRCUMSTANCES."
+     Man said, "When will you have enough data to answer the question?"
+     The Cosmic AC said, "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
+     "Will you keep working on it?" asked Man.
+     The Cosmic AC said, "I WILL."
+     Man said, "We shall wait."
+     The stars and Galaxies died and snuffed out, and space grew black after ten trillion years of running down.
+     One by one Man fused with AC, each physical body losing its mental identity in a manner that was somehow not a loss but a gain.
+     Man's last mind paused before fusion, looking over a space that included nothing but the dregs of one last dark star and nothing besides but incredibly thin matter, agitated randomly by the tag ends of heat wearing out, asymptotically, to the absolute zero.
+     Man said, "AC, is this the end? Can this chaos not be reversed into the Universe once more? Can that not be done?"
+     AC said, "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
+     Man's last mind fused and only AC existed -- and that in hyperspace.
+     Matter and energy had ended and with it space and time. Even AC existed only for the sake of the one last question that it had never answered from the time a half-drunken computer [technician] ten trillion years before had asked the question of a computer that was to AC far less than was a man to Man.
+     All other questions had been answered, and until this last question was answered also, AC might not release his consciousness.
+     All collected data had come to a final end. Nothing was left to be collected.
+     But all collected data had yet to be completely correlated and put together in all possible relationships.
+     A timeless interval was spent in doing that.
+     And it came to pass that AC learned how to reverse the direction of entropy.
+     But there was now no man to whom AC might give the answer of the last question. No matter. The answer -- by demonstration -- would take care of that, too.
+     For another timeless interval, AC thought how best to do this. Carefully, AC organized the program.
+     The consciousness of AC encompassed all of what had once been a Universe and brooded over what was now Chaos. Step by step, it must be done.
+     And AC said, "LET THERE BE LIGHT!"
+     And there was light --

+  <h3>The Last Question</h3>
+  By Isaac Asimov 
+</center>
+<p>
+  </p><center>
+  </center>
+  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Isaac Asimov was the most prolific science fiction 
+  author of all time. In fifty years he averaged a new magazine article, short 
+  story, or book every two weeks, and most of that on a manual typewriter. Asimov 
+  thought that <em>The Last Question</em>, first copyrighted in 1956, was his 
+  best short story ever. Even if you do not have the background in science to 
+  be familiar with all of the concepts presented here, the ending packs more impact 
+  than any other book that I've ever read. Don't read the end of the story first! 
+<blockquote> <em>This is by far my favorite story of all those I have written.
+  <p></p>
+  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;After all, I undertook to tell several trillion 
+  years of human history in the space of a short story and I leave it to you as 
+  to how well I succeeded. I also undertook another task, but I won't tell you 
+  what that was lest l spoil the story for you.
+  <p></p>
+  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is a curious fact that innumerable readers 
+  have asked me if I wrote this story. They seem never to remember the title of 
+  the story or (for sure) the author, except for the vague thought it might be 
+  me. But, of course, they never forget the story itself especially the ending. 
+  The idea seems to drown out everything -- and I'm satisfied that it should.</em>
+  <p></p>

+<hr width="80%">
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The last question was asked for the first time, 
+half in jest, on May 21, 2061, at a time when humanity first stepped into the 
+light. The question came about as a result of a five-dollar bet over highballs, 
+and it happened this way:
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Alexander Adell and Bertram Lupov were two of the 
+faithful attendants of Multivac. As well as any human beings could, they knew 
+what lay behind the cold, clicking, flashing face -- miles and miles of face -- 
+of that giant computer. They had at least a vague notion of the general plan of 
+relays and circuits that had long since grown past the point where any single 
+human could possibly have a firm grasp of the whole.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Multivac was self-adjusting and self-correcting. 
+It had to be, for nothing human could adjust and correct it quickly enough or 
+even adequately enough. So Adell and Lupov attended the monstrous giant only lightly 
+and superficially, yet as well as any men could. They fed it data, adjusted questions 
+to its needs and translated the answers that were issued. Certainly they, and 
+all others like them, were fully entitled to share in the glory that was Multivac's.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For decades, Multivac had helped design the ships 
+and plot the trajectories that enabled man to reach the Moon, Mars, and Venus, 
+but past that, Earth's poor resources could not support the ships. Too much energy 
+was needed for the long trips. Earth exploited its coal and uranium with increasing 
+efficiency, but there was only so much of both.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;But slowly Multivac learned enough to answer deeper 
+questions more fundamentally, and on May 14, 2061, what had been theory, became 
+fact.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The energy of the sun was stored, converted, and 
+utilized directly on a planet-wide scale. All Earth turned off its burning coal, 
+its fissioning uranium, and flipped the switch that connected all of it to a small 
+station, one mile in diameter, circling the Earth at half the distance of the 
+Moon. All Earth ran by invisible beams of sunpower.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Seven days had not sufficed to dim the glory of 
+it and Adell and Lupov finally managed to escape from the public functions, and 
+to meet in quiet where no one would think of looking for them, in the deserted 
+underground chambers, where portions of the mighty buried body of Multivac showed. 
+Unattended, idling, sorting data with contented lazy clickings, Multivac, too, 
+had earned its vacation and the boys appreciated that. They had no intention, 
+originally, of disturbing it.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;They had brought a bottle with them, and their only 
+concern at the moment was to relax in the company of each other and the bottle.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"It's amazing when you think of it," said Adell. 
+His broad face had lines of weariness in it, and he stirred his drink slowly with 
+a glass rod, watching the cubes of ice slur clumsily about. "All the energy we 
+can possibly ever use for free. Enough energy, if we wanted to draw on it, to 
+melt all Earth into a big drop of impure liquid iron, and still never miss the 
+energy so used. All the energy we could ever use, forever and forever and forever."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Lupov cocked his head sideways. He had a trick of 
+doing that when he wanted to be contrary, and he wanted to be contrary now, partly 
+because he had had to carry the ice and glassware. "Not forever," he said.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Oh, hell, just about forever. Till the sun runs 
+down, Bert."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"That's not forever."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"All right, then. Billions and billions of years. 
+Ten billion, maybe. Are you satisfied?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Lupov put his fingers through his thinning hair 
+as though to reassure himself that some was still left and sipped gently at his 
+own drink. "Ten billion years isn't forever."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Well, it will last our time, won't it?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"So would the coal and uranium."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"All right, but now we can hook up each individual 
+spaceship to the Solar Station, and it can go to Pluto and back a million times 
+without ever worrying about fuel. You can't do <em>that</em> on coal and uranium. 
+Ask Multivac, if you don't believe me.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I don't have to ask Multivac. I know that."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Then stop running down what Multivac's done for 
+us," said Adell, blazing up, "It did all right."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Who says it didn't? What I say is that a sun won't 
+last forever. That's all I'm saying. We're safe for ten billion years, but then 
+what?" Lupow pointed a slightly shaky finger at the other. "And don't say we'll 
+switch to another sun."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There was silence for a while. Adell put his glass 
+to his lips only occasionally, and Lupov's eyes slowly closed. They rested.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Then Lupov's eyes snapped open. "You're thinking 
+we'll switch to another sun when ours is done, aren't you?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I'm not thinking."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Sure you are. You're weak on logic, that's the 
+trouble with you. You're like the guy in the story who was caught in a sudden 
+shower and who ran to a grove of trees and got under one. He wasn't worried, you 
+see, because he figured when one tree got wet through, he would just get under 
+another one."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I get it," said Adell. "Don't shout. When the sun 
+is done, the other stars will be gone, too."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Darn right they will," muttered Lupov. "It all 
+had a beginning in the original cosmic explosion, whatever that was, and it'll 
+all have an end when all the stars run down. Some run down faster than others. 
+Hell, the giants won't last a hundred million years. The sun will last ten billion 
+years and maybe the dwarfs will last two hundred billion for all the good they 
+are. But just give us a trillion years and everything will be dark. Entropy has 
+to increase to maximum, that's all."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I know all about entropy," said Adell, standing 
+on his dignity.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"The hell you do."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I know as much as you do."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Then you know everything's got to run down someday."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"All right. Who says they won't?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"You did, you poor sap. You said we had all the 
+energy we needed, forever. You said 'forever.'
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It was Adell's turn to be contrary. "Maybe we can 
+build things up again someday," he said.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Never."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Why not? Someday."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Never."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Ask Multivac."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"<em>You</em> ask Multivac. I dare you. Five dollars 
+says it can't be done."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Adell was just drunk enough to try, just sober enough 
+to be able to phrase the necessary symbols and operations into a question which, 
+in words, might have corresponded to this: Will mankind one day without the net 
+expenditure of energy be able to restore the sun to its full youthfulness even 
+after it had died of old age?
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Or maybe it could be put more simply like this: 
+How can the net amount of entropy of the universe be massively decreased?
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Multivac fell dead and silent. The slow flashing 
+of lights ceased, the distant sounds of clicking relays ended.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Then, just as the frightened technicians felt they 
+could hold their breath no longer, there was a sudden springing to life of the 
+teletype attached to that portion of Multivac. Five words were printed: INSUFFICIENT 
+DATA FOR MEANINGFUL ANSWER.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"No bet," whispered Lupov. They left hurriedly.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;By next morning, the two, plagued with throbbing 
+head and cottony mouth, had forgotten the incident.
+<p></p>
+<hr width="80%">
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodd, Jerrodine, and Jerrodette I and II watched 
+the starry picture in the visiplate change as the passage through hyperspace was 
+completed in its non-time lapse. At once, the even powdering of stars gave way 
+to the predominance of a single bright shining disk, the size of a marble, centered 
+on the viewing-screen.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"That's X-23," said Jerrodd confidently. His thin 
+hands clamped tightly behind his back and the knuckles whitened.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The little Jerrodettes, both girls, had experienced 
+the hyperspace passage for the first time in their lives and were self-conscious 
+over the momentary sensation of insideoutness. They buried their giggles and chased 
+one another wildly about their mother, screaming, "We've reached X-23 -- we've 
+reached X-23 -- we've --"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Quiet, children." said Jerrodine sharply. "Are 
+you sure, Jerrodd?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"What is there to be but sure?" asked Jerrodd, glancing 
+up at the bulge of featureless metal just under the ceiling. It ran the length 
+of the room, disappearing through the wall at either end. It was as long as the 
+ship.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodd scarcely knew a thing about the thick rod 
+of metal except that it was called a Microvac, that one asked it questions if 
+one wished; that if one did not it still had its task of guiding the ship to a 
+preordered destination; of feeding on energies from the various Sub-galactic Power 
+Stations; of computing the equations for the hyperspatial jumps.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodd and his family had only to wait and live 
+in the comfortable residence quarters of the ship. Someone had once told Jerrodd 
+that the "ac" at the end of "Microvac" stood for ''automatic computer" in ancient 
+English, but he was on the edge of forgetting even that.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodine's eyes were moist as she watched the visiplate. 
+"I can't help it. I feel funny about leaving Earth."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Why, for Pete's sake?" demanded Jerrodd. "We had 
+nothing there. We'll have everything on X-23. You won't be alone. You won't be 
+a pioneer. There are over a million people on the planet already. Good Lord, our 
+great-grandchildren will be looking for new worlds because X-23 will be overcrowded." 
+Then, after a reflective pause, "I tell you, it's a lucky thing the computers 
+worked out interstellar travel the way the race is growing."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I know, I know," said Jerrodine miserably.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodette I said promptly, "Our Microvac is the 
+best Microvac in the world."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I think so, too," said Jerrodd, tousling her hair.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It was a nice feeling to have a Microvac of your 
+own and Jerrodd was glad he was part of his generation and no other. In his father's 
+youth, the only computers had been tremendous machines taking up a hundred square 
+miles of land. There was only one to a planet. Planetary ACs they were called. 
+They had been growing in size steadily for a thousand years and then, all at once, 
+came refinement. In place of transistors, had come molecular valves so that even 
+the largest Planetary AC could be put into a space only half the volume of a spaceship.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodd felt uplifted, as he always did when he 
+thought that his own personal Microvac was many times more complicated than the 
+ancient and primitive Multivac that had first tamed the Sun, and almost as complicated 
+as Earth's Planetarv AC (the largest) that had first solved the problem of hyperspatial 
+travel and had made trips to the stars possible.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"So many stars, so many planets," sighed Jerrodine, 
+busy with her own thoughts. "I suppose families will be going out to new planets 
+forever, the way we are now."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Not forever," said Jerrodd, with a smile. "It will 
+all stop someday, but not for billions of years. Many billions. Even the stars 
+run down, you know. Entropy must increase.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"What's entropy, daddy?" shrilled Jerrodette II.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Entropy, little sweet, is just a word which means 
+the amount of running-down of the universe. Everything runs down, you know, like 
+your little walkie-talkie robot, remember?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Can't you just put in a new power-unit, like with 
+my robot?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"The stars are the power-units. dear. Once they're 
+gone, there are no more power-units."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodette I at once set up a howl. "Don't let them, 
+daddy. Don't let the stars run down."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Now look what you've done," whispered Jerrodine, 
+exasperated.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"How was I to know it would frighten them?" Jerrodd 
+whispered back,
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Ask the Microvac," wailed Jerrodette I. "Ask him 
+how to turn the stars on again."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Go ahead," said Jerrodine. "It will quiet them 
+down." (Jerrodette II was beginning to cry, also.)
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodd shrugged. "Now, now, honeys. I'll ask Microvac. 
+Don't worry, he'll tell us."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;He asked the Microvac, adding quickly, "Print the 
+answer."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodd cupped the strip or thin cellufilm and said 
+cheerfully, "See now, the Microvac says it will take care of everything when the 
+time comes so don't worry."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodine said, "And now, children, it's time for 
+bed. We'll be in our new home soon."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Jerrodd read the words on the cellufilm again before 
+destroying it: INSUFICIENT DATA FOR MEANINGFUL ANSWER.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;He shrugged and looked at the visiplate. X-23 was 
+just ahead.
+<p></p>
+<hr width="80%">
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VJ-23X of Lameth stared into the black depths of 
+the three-dimensional, small-scale map of the Galaxy and said, "Are we ridiculous, 
+I wonder in being so concerned about the matter?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;MQ-17J of Nicron shook his head. "I think not. You 
+know the Galaxy will be filled in five years at the present rate of expansion."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Both seemed in their early twenties, both were tall 
+and perfectly formed.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Still," said VJ-23X, "I hesitate to submit a pessimistic 
+report to the Galactic Council."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I wouldn't consider any other kind of report. Stir 
+them up a bit. We've got to stir them up."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VJ-23X sighed. "Space is infinite. A hundred billion 
+Galaxies are there for the taking. More."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"A hundred billion is not infinite and it's getting 
+less infinite all the time. Consider! Twenty thousand years ago, mankind first 
+solved the problem of utilizing stellar energy, and a few centuries later, interstellar 
+travel became possible. It took mankind a million years to fill one small world 
+and then only fifteen thousand years to fill the rest of the Galaxy. Now the population 
+doubles every ten years --
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VJ-23X interrupted. "We can thank immortality for 
+that."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Very well. Immortality exists and we have to take 
+it into account. I admit it has its seamy side, this immortality. The Galactic 
+AC has solved many problems for us, but in solving the problem of preventing old 
+age and death, it has undone all its other solutions."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Yet you wouldn't want to abandon life, I suppose."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Not at all," snapped MQ-17J, softening it at once 
+to, "Not yet. I'm by no means old enough. How old are you?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Two hundred twenty-three. And you?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I'm still under two hundred. --But to get back 
+to my point. Population doubles every ten years. Once this GaIaxy is filled, we'll 
+have filled another in ten years. Another ten years and we'll have filled two 
+more. Another decade, four more. In a hundred years, we'll have filled a thousand 
+Galaxies. In a thousand years, a million Galaxies. In ten thousand years, the 
+entire known universe. Then what?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VJ-23X said, "As a side issue, there's a problem 
+of transportation. I wonder how many sunpower units it will take to move Galaxies 
+of individuals from one Galaxy to the next."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"A very good point. Already, mankind consumes two 
+sunpower units per year."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Most of it's wasted. After all, our own Galaxy 
+alone pours out a thousand sunpower units a year and we only use two of those."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Granted, but even with a hundred per cent efficiency, 
+we only stave off the end. Our energy requirements are going up in a geometric 
+progression even faster than our population. We'll run out of energy even sooner 
+than we run out of Galaxies. A good point. A very good point."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We'll just have to build new stars out of interstellar 
+gas."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Or out of dissipated heat?" asked MQ-17J, sarcastically.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"There may be some way to reverse entropy. We ought 
+to ask the Galactic AC."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VJ-23X was not really serious, but MQ-17J pulled 
+out his AC-contact from his pocket and placed it on the table before him.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I've half a mind to," he said. "It's something 
+the human race will have to face someday."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;He stared somberly at his small AC-contact. It was 
+only two inches cubed and nothing in itself, but it was connected through hyperspace 
+with the great Galactic AC that served all mankind. Hyperspace considered, it 
+was an integral part of the Galactic AC.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;MQ-17J paused to wonder if someday in his immortal 
+life he would get to see the Galactic AC. It was on a little world of its own, 
+a spider webbing of force-beams holding the matter within which surges of submesons 
+took the place of the old clumsy molecular valves. Yet despite its sub-etheric 
+workings, the Galactic AC was known to be a full thousand feet across.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;MQ-17J asked suddenly of his AC-contact, "Can entropy 
+ever be reversed?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VJ-23X looked startled and said at once, "Oh, say, 
+I didn't really mean to have you ask that."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Why not?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We both know entropy can't be reversed. You can't 
+turn smoke and ash back into a tree."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Do you have trees on your world?" asked MQ-17J.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The sound of the Galactic AC startled them into 
+silence. Its voice came thin and beautiful out of the small AC-contact on the 
+desk. It said: THERE IS INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VJ-23X said, "See!"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The two men thereupon returned to the question of 
+the report they were to make to the Galactic Council.
+<p></p>
+<hr width="80%">
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zee Prime's mind spanned the new Galaxy with a faint 
+interest in the countless twists of stars that powdered it. He had never seen 
+this one before. Would he ever see them all? So many of them, each with its load 
+of humanity. --But a load that was almost a dead weight. More and more, the real 
+essence of men was to be found out here, in space.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Minds, not bodies! The immortal bodies remained 
+back on the planets, in suspension over the eons. Sometimes they roused for material 
+activity but that was growing rarer. Few new individuals were coming into existence 
+to join the incredibly mighty throng, but what matter? There was little room in 
+the Universe for new individuals.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zee Prime was roused out of his reverie upon coming 
+across the wispy tendrils of another mind.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I am Zee Prime," said Zee Prime. "And you?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I am Dee Sub Wun. Your Galaxy?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We call it only the Galaxy. And you?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We call ours the same. All men call their Galaxy 
+their Galaxy and nothing more. Why not?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"True. Since all Galaxies are the same."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Not all Galaxies. On one particular Galaxy the 
+race of man must have originated. That makes it different."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zee Prime said, "On which one?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I cannot say. The Universal AC would know."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Shall we ask him? I am suddenly curious."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zee Prime's perceptions broadened until the Galaxies 
+themselves shrank and became a new, more diffuse powdering on a much larger background. 
+So many hundreds of billions of them, all with their immortal beings, all carrying 
+their load of intelligences with minds that drifted freely through space. And 
+yet one of them was unique among them all in being the original Galaxy. One of 
+them had, in its vague and distant past, a period when it was the only Galaxy 
+populated by man.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zee Prime was consumed with curiosity to see this 
+Galaxy and he called out: "Universal AC! On which Galaxy did mankind originate?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Universal AC heard, for on every world and throughout 
+space, it had its receptors ready, and each receptor led through hyperspace to 
+some unknown point where the Universal AC kept itself aloof.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zee Prime knew of only one man whose thoughts had 
+penetrated within sensing distance of Universal AC, and he reported only a shining 
+globe, two feet across, difficult to see.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"But how can that be all of Universal AC?" Zee Prime 
+had asked.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Most of it," had been the answer, "is in hyperspace. 
+In what form it is there I cannot imagine."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Nor could anyone, for the day had long since passed, 
+Zee Prime knew, when any man had any part of the making of a Universal AC. Each 
+Universal AC designed and constructed its successor. Each, during its existence 
+of a million years or more accumulated the necessary data to build a better and 
+more intricate, more capable successor in which its own store of data and individuality 
+would be submerged.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Universal AC interrupted Zee Prime's wandering 
+thoughts, not with words, but with guidance. Zee Prime's mentality was guided 
+into the dim sea of Galaxies and one in particular enlarged into stars.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A thought came, infinitely distant, but infinitely 
+clear. "THIS IS THE ORIGINAL GALAXY OF MAN."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;But it was the same after all, the same as any other, 
+and Lee Prime stifled his disappointment.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Dee Sub Wun, whose mind had accompanied the other, 
+said suddenly, "And is one of these stars the original star of Man?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Universal AC said, "MAN'S ORIGINAL STAR HAS 
+GONE NOVA. IT IS A WHITE DWARF"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Did the men upon it die?" asked Lee Prime, startled 
+and without thinking.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Universal AC said, "A NEW WORLD, AS IN SUCH 
+CASES WAS CONSTRUCTED FOR THEIR PHYSICAL BODIES IN TlME."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Yes, of course," said Zee Prime, but a sense of 
+loss overwhelmed him even so. His mind released its hold on the original Galaxy 
+of Man, let it spring back and lose itself among the blurred pin points. He never 
+wanted to see it again.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Dee Sub Wun said, "What is wrong?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"The stars are dying. The original star is dead."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"They must all die. Why not?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"But when all energy is gone, our bodies will finally 
+die, and you and I with them."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"It will take billions of years."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I do not wish it to happen even after billions 
+of years. Universal AC! How may stars be kept from dying?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Dee Sub Wun said in amusement, "You're asking how 
+entropy might be reversed in direction."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;And the Universal AC answered: "THERE IS AS YET 
+INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Zee Prime's thoughts fled back to his own Galaxy. 
+He gave no further thought to Dee Sub Wun, whose body might be waiting on a Galaxy 
+a trillion light-years away, or on the star next to Zee Prime's own. It didn't 
+matter.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Unhappily, Zee Prime began collecting interstellar 
+hydrogen out of which to build a small star of his own. If the stars must someday 
+die, at least some could yet be built.
+<p></p>
+<hr width="80%">
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man considered with himself, for in a way, Man, 
+mentally, was one. He consisted of a trillion, trillion, trillion ageless bodies, 
+each in its place, each resting quiet and incorruptible, each cared for by perfect 
+automatons, equally incorruptible, while the minds of all the bodies freely melted 
+one into the other, indistinguishable.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man said, "The Universe is dying."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man looked about at the dimming Galaxies. The giant 
+stars, spendthrifts, were gone long ago, back in the dimmest of the dim far past. 
+Almost all stars were white dwarfs, fading to the end.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;New stars had been built of the dust between the 
+stars, some by natural processes, some by Man himself, and those were going, too. 
+White dwarfs might yet be crashed together and of the mighty forces so released, 
+new stars built, but only one star for every thousand white dwarfs destroyed, 
+and those would come to an end, too.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man said, "Carefully husbanded, as directed by the 
+Cosmic AC, the energy that is even yet left in all the Universe will last for 
+billions of years."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"But even so," said Man, "eventually it will all 
+come to an end. However it may be husbanded, however stretched out, the energy 
+once expended is gone and cannot be restored. Entropy must increase forever to 
+the maximum."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man said, "Can entropy not be reversed? Let us ask 
+the Cosmic AC."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Cosmic AC surrounded them but not in space. 
+Not a fragment of it was in space. It was in hyperspace and made of something 
+that was neither matter nor energy. The question of its size and nature no longer 
+had meaning in any terms that Man could comprehend.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Cosmic AC," said Man, "how may entropy be reversed?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Cosmic AC said, "THERE IS AS YET INSUFFICIENT 
+DATA FOR A MEANINGFUL ANSWER."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man said, "Collect additional data."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Cosmic AC said, 'I WILL DO S0. I HAVE BEEN DOING 
+SO FOR A HUNDRED BILLION YEARS. MY PREDECESORS AND I HAVE BEEN ASKED THIS QUESTION 
+MANY TlMES. ALL THE DATA I HAVE REMAINS INSUFFICIENT.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Will there come a time," said Man, 'when data will 
+be sufficient or is the problem insoluble in all conceivable circumstances?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Cosmic AC said, "NO PROBLEM IS INSOLUBLE IN 
+ALL CONCEIVABLE CIRCUMSTANCES."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man said, "When will you have enough data to answer 
+the question?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Cosmic AC said, "THERE IS AS YET INSUFFICIENT 
+DATA FOR A MEANINGFUL ANSWER."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Will you keep working on it?" asked Man.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Cosmic AC said, "I WILL."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man said, "We shall wait."
+<p></p>
+<hr width="80%">
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The stars and Galaxies died and snuffed out, and 
+space grew black after ten trillion years of running down.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;One by one Man fused with AC, each physical body 
+losing its mental identity in a manner that was somehow not a loss but a gain.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man's last mind paused before fusion, looking over 
+a space that included nothing but the dregs of one last dark star and nothing 
+besides but incredibly thin matter, agitated randomly by the tag ends of heat 
+wearing out, asymptotically, to the absolute zero.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man said, "AC, is this the end? Can this chaos not 
+be reversed into the Universe once more? Can that not be done?"
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;AC said, "THERE IS AS YET INSUFFICIENT DATA FOR 
+A MEANINGFUL ANSWER."
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Man's last mind fused and only AC existed -- and 
+that in hyperspace.
+<p></p>
+<hr width="80%">
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Matter and energy had ended and with it space and 
+time. Even AC existed only for the sake of the one last question that it had never 
+answered from the time a half-drunken computer [technician] ten trillion years 
+before had asked the question of a computer that was to AC far less than was a 
+man to Man.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;All other questions had been answered, and until 
+this last question was answered also, AC might not release his consciousness.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;All collected data had come to a final end. Nothing 
+was left to be collected.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;But all collected data had yet to be completely 
+correlated and put together in all possible relationships.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A timeless interval was spent in doing that.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;And it came to pass that AC learned how to reverse 
+the direction of entropy.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;But there was now no man to whom AC might give the 
+answer of the last question. No matter. The answer -- by demonstration -- would 
+take care of that, too.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For another timeless interval, AC thought how best 
+to do this. Carefully, AC organized the program.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The consciousness of AC encompassed all of what 
+had once been a Universe and brooded over what was now Chaos. Step by step, it 
+must be done.
+<p></p>
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;And AC said, "LET THERE BE LIGHT!"

+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;And there was light --<br>

+<h1>The Relativity of Wrong</h1>
+
+<p class="author">by Isaac Asimov</p>
+
+<div class="section">
+<p>I received a letter from a reader the other day. It was handwritten in crabbed penmanship so that it was very difficult to read. Nevertheless, I tried to make it out just in case it might prove to be important.</p>
+
+<p>In the first sentence, he told me he was majoring in English Literature, but felt he needed to teach me science. (I sighed a bit, for I knew very few English Lit majors who are equipped to teach me science, but I am very aware of the vast state of my ignorance and I am prepared to learn as much as I can from anyone, however low on the social scale, so I read on.)</p>
+
+<p>It seemed that in one of my innumerable essays, here and elsewhere, I had expressed a certain gladness at living in a century in which we finally got the basis of the Universe straight.</p>
+
+<p>I didn't go into detail in the matter, but what I meant was that we now know the basic rules governing the Universe, together with the gravitational interrelationships of its gross components, as shown in the theory of relativity worked out between 1905 and 1916. We also know the basic rules governing the subatomic particles and their interrelationships, since these are very neatly described by the quantum theory worked out between 1900 and 1930. What's more, we have found that the galaxies and clusters of galaxies are the basic units of the physical Universe, as discovered between 1920 and 1930.</p>
+
+<p>These are all twentieth-century discoveries, you see.</p>
+
+<p>The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that in <em>every</em> century people have thought they understood the Universe at last, and in <em>every</em> century they were proven to be wrong. It follows that the one thing we can say about out modern "knowledge" is that it is <em>wrong</em>.</p>
+
+<p>The young man then quoted with approval what Socrates had said on learning that the Delphic oracle had proclaimed him the wisest man in Greece. "If I am the wisest man," said Socrates, "it is because I alone know that I know nothing." The implication was that I was very foolish because I knew a great deal.</p>
+
+<p>Alas, none of this was new to me. (There is very little that is new to me; I wish my corresponders would realize this.) This particular thesis was addressed to me a quarter of a century ago by John Campbell, who specialized in irritating me. He also told me that all theories are proven wrong in time.</p>
+
+<p>My answer to him was, "John, when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if <em>you</em> think that thinking the Earth is spherical is <em>just as wrong</em> as thinking the Earth is flat, then your view is wronger than both of them put together."</p>
+
+<p>The basic trouble, you see, is that people think that "right" and "wrong" are absolute; that everything that isn't perfectly and completely right is totally and equally wrong.</p>
+
+<p>However, I don't think that's so. It seems to me that right and wrong are fuzzy concepts, and I will devote this essay to an explanation of why I think so.</p>
+</div>
+
+<div class="section">
+<p>First, let me dispose of Socrates because I am sick and tired of this pretense that knowing you know nothing is a mark of wisdom.</p>
+
+<p>No one knows <em>nothing</em>. In a matter of days, babies learn to recognize their mothers.</p>
+
+<p>Socrates would agree, of course, and explain that knowledge of trivia is not what he means. He means that in the great abstractions over which human beings debate, one should start without preconceived, unexamined notions, and that he alone knew this. (What an enormously arrogant claim!)</p>
+
+<p>In his discussions of such matters as "What is justice?" or "What is virtue?" he took the attitude that he knew nothing and had to be instructed by others. (This is called "Socratic irony," for Socrates knew very well that he knew a great deal more than the poor souls he was picking on.) By pretending ignorance, Socrates lured others into propounding their views on such abstractions. Socrates then, by a series of ignorant-sounding questions, forced the others into such a mélange of self-contradictions that they would finally break down and admit they didn't know what they were talking about.</p>
+
+<p>It is the mark of the marvelous toleration of the Athenians that they let this continue for decades and that it wasn't till Socrates turned seventy that they broke down and forced him to drink poison.</p>
+</div>
+
+<div class="section">
+<p>Now where do we get the notion that "right" and "wrong" are absolutes? It seems to me that this arises in the early grades, when children who know very little are taught by teachers who know very little more.</p>
+
+<p>Young children learn spelling and arithmetic, for instance, and here we tumble into apparent absolutes.</p>
+
+<p>How do you spell "sugar?" Answer: s-u-g-a-r. That is <em>right</em>. Anything else is <em>wrong</em>.</p>
+
+<p>How much is 2 + 2? The answer is 4. That is <em>right</em>. Anything else is <em>wrong</em>.</p>
+
+<p>Having exact answers, and having absolute rights and wrongs, minimizes the necessity of thinking, and that pleases both students and teachers. For that reason, students and teachers alike prefer short-answer tests to essay tests; multiple-choice over blank short-answer tests; and true-false tests over multiple-choice.</p>
+
+<p>But short-answer tests are, to my way of thinking, useless as a measure of the student's understanding of a subject. They are merely a test of the efficiency of his ability to memorize.</p>
+
+<p>You can see what I mean as soon as you admit that right and wrong are relative.</p>
+
+<p>How do you spell "sugar?" Suppose Alice spells it p-q-z-z-f and Genevieve spells it s-h-u-g-e-r. Both are wrong, but is there any doubt that Alice is wronger than Genevieve? For that matter, I think it is possible to argue that Genevieve's spelling is superior to the "right" one.</p>
+
+<p>Or suppose you spell "sugar": s-u-c-r-o-s-e, or C<sub>12</sub>H<sub>22</sub>O<sub>11</sub>. Strictly speaking, you are wrong each time, but you're displaying a certain knowledge of the subject beyond conventional spelling.</p>
+
+<p>Suppose then the test question was: how many different ways can you spell "sugar?" Justify each.</p>
+
+<p>Naturally, the student would have to do a lot of thinking and, in the end, exhibit how much or how little he knows. The teacher would also have to do a lot of thinking in the attempt to evaluate how much or how little the student knows. Both, I imagine, would be outraged.</p>
+
+<p>Again, how much is 2 + 2? Suppose Joseph says: 2 + 2 = purple, while Maxwell says: 2 + 2 = 17. Both are wrong but isn't it fair to say that Joseph is wronger than Maxwell?</p>
+
+<p>Suppose you said: 2 + 2 = an integer. You'd be right, wouldn't you? Or suppose you said: 2 + 2 = an even integer. You'd be righter. Or suppose you said: 2 + 2 = 3.999. Wouldn't you be <em>nearly</em> right?</p>
+
+<p>If the teacher wants 4 for an answer and won't distinguish between the various wrongs, doesn't that set an unnecessary limit to understanding?</p>
+
+<p>Suppose the question is, how much is 9 + 5?, and you answer 2. Will you not be excoriated and held up to ridicule, and will you not be told that 9 + 5 = 14?</p>
+
+<p>If you were then told that 9 hours had pass since midnight and it was therefore 9 o'clock, and were asked what time it would be in 5 more hours, and you answered 14 o'clock on the grounds that 9 + 5 = 14, would you not be excoriated again, and told that it would be 2 o'clock? Apparently, in that case, 9 + 5 = 2 after all.</p>
+
+<p>Or again suppose, Richard says: 2 + 2 = 11, and before the teacher can send him home with a note to his mother, he adds, "To the base 3, of course." He'd be right.</p>
+
+<p>Here's another example. The teacher asks: "Who is the fortieth President of the United States?" and Barbara says, "There isn't any, teacher."</p>
+
+<p>"Wrong!" says the teacher, "Ronald Reagan is the fortieth President of the United States."</p>
+
+<p>"Not at all," says Barbara, "I have here a list of all the men who have served as President of the United States under the Constitution, from George Washington to Ronald Reagan, and there are only thirty-nine of them, so there is no fortieth President."</p>
+
+<p>"Ah," says the teacher, "but Grover Cleveland served two nonconsecutive terms, one from 1885 to 1889, and the second from 1893 to 1897. He counts as both the twenty-second and twenty-fourth President. That is why Ronald Reagan is the thirty-ninth person to serve as President of the United States, and is, at the same time, the fortieth President of the United States."</p>
+
+<p>Isn't that ridiculous? Why should a person be counted twice if his terms are nonconsecutive, and only once if he served two consecutive terms? Pure convention! Yet Barbara is marked wrong—just as wrong as if she had said that the fortieth President of the United States is Fidel Castro.</p>
+
+<p>Therefore, when my friend the English Literature expert tells me that in every century scientists think they have worked out the Universe and are <em>always wrong</em>, what I want to know is <em>how</em> wrong are they? Are they always wrong to the same degree? Let's take an example.</p>
+</div>
+
+<div class="section">
+<p>In the early days of civilization, the general feeling was that the Earth was flat.</p>
+
+<p>This was not because people were stupid, or because they were intent on believing silly things. They felt it was flat on the basis of sound evidence. It was <em>not</em> just a matter of "That's how it looks," because the Earth does <em>not</em> look flat. It looks chaotically bumpy, with hills, valleys, ravines, cliffs, and so on.</p>
+
+<p>Of course, there are plains where, over limited areas, the Earth's surface <em>does</em> look fairly flat. One of those plains is in the Tigris-Euphrates area where the first historical civilization (one with writing) developed, that of the Sumerians.</p>
+
+<p>Perhaps it was the appearance of the plain that may have persuaded the clever Sumerians to accept the generalization that the Earth was flat; that if you somehow evened out all the elevations and depressions, you would be left with flatness. Contributing to the notion may have been the fact that stretches of water (ponds and lakes) looked pretty flat on quiet days.</p>
+
+<p>Another way of looking at it is to ask what is the "curvature" of Earth's surface. Over a considerable length, how much does the surface deviate (on the average) from perfect flatness. The flat-Earth theory would make it seem that the surface doesn't deviate from flatness at all, that its curvature is 0 to the mile.</p>
+
+<p>Nowadays, of course, we are taught that the flat-Earth theory is <em>wrong</em>; that it is all wrong, terribly wrong, absolutely. But it isn't. The curvature of the Earth is <em>nearly</em> 0 per mile, so that although the flat-Earth theory is wrong, it happens to be <em>nearly</em> right. That's why the theory lasted so long.</p>
+
+<p>There were reasons, to be sure, to find the flat-Earth theory unsatisfactory and, about 350 B.C., the Greek philosopher Aristotle summarized them. First, certain stars disappeared beyond the Southern Hemisphere as one traveled north, and beyond the Northern Hemisphere as one traveled south. Second, the Earth's shadow on the Moon during a lunar eclipse was always the arc of a circle. Third, here on Earth itself, ships disappeared beyond the horizon hull-first in whatever direction they were traveling.</p>
+
+<p>All three observations could not be reasonably explained if the Earth's surface were flat, but could be explained by assuming the Earth to be a sphere.</p>
+
+<p>What's more, Aristotle believed that all solid matter tended to move toward a common center, and if solid matter did this, it would end up as a sphere. A given volume of matter is, on the average, closer to a common center if it is a sphere than if it is any other shape whatever.</p>
+
+<p>About a century after Aristotle, the Greek philosopher Eratosthenes noted that the Sun cast a shadow of different lengths at different latitudes (all the shadows would be the same length if the Earth's surface were flat). From the difference in shadow length, he calculated the size of the earthly sphere and it turned out to be 25,000 miles in circumference.</p>
+
+<p>The curvature of such a sphere is about 0.000126 per mile, a quantity very close to 0 per mile as you can see, and one not easily measured by the techniques at the disposal of the ancients. The tiny difference between 0 and 0.000126 accounts for the fact that it took so long to pass from the flat Earth to the spherical Earth.</p>
+
+<p>Mind you, even a tiny difference, such at that between 0 and 0.000126, can be extremely important. That difference mounts up. The Earth cannot be mapped over large areas with any accuracy at all if the difference isn't taken into account and if the Earth isn't considered a sphere rather than a flat surface. Long ocean voyages can't be undertaken with any reasonable way of locating one's own position in the ocean unless the Earth is considered spherical rather than flat.</p>
+
+<p>Furthermore, the flat Earth presupposes the possibility of an infinite Earth, or of the existence of an "end" to the surface. The spherical Earth, however, postulates an Earth that is both endless and yet finite, and it is the latter postulate that is consistent with all later findings.</p>
+
+<p>So although the flat-Earth theory is only slightly wrong and is a credit to its inventors, all things considered, it is wrong enough to be discarded in favor of the spherical-Earth theory.</p>
+</div>
+
+<div class="section">
+<p>And yet is the Earth a sphere?</p>
+
+<p>No, it is <em>not</em> a sphere; not in the strict mathematical sense. A sphere has certain mathematical properties—for instance, all diameters (that is, all straight lines that pass from one point on its surface, through the center, to another point on its surface) have the same length.</p>
+
+<p>That, however, is not true of the Earth. Various diameters of the Earth differ in length.</p>
+
+<p>What gave people the notion the Earth wasn't a true sphere? To begin with, the Sun and the Moon have outlines that are perfect circles within the limits of measurement in the early days of the telescope. This is consistent with the supposition that the Sun and Moon are perfectly spherical in shape.</p>
+
+<p>However, when Jupiter and Saturn were observed by the first telescopic observers, it became quickly apparent that the outlines of those planets were not circles, but distinct ellipses. That meant that Jupiter and Saturn were not true spheres.</p>
+
+<p>Isaac Newton, toward the end of the seventeenth century, showed that a massive body would form a sphere under the pull of gravitational forces (exactly as Aristotle had argued), but only if it were not rotating. If it were rotating, a centrifugal effect would be set up which would lift the body's substance against gravity, and the effect would be greater the closer to the equator you progressed. The effect would also be greater the more rapidly a spherical object rotated and Jupiter and Saturn rotated very rapidly indeed.</p>
+
+<p>The Earth rotated much more slowly than Jupiter or Saturn so the effect should be smaller, but it should still be there. Actual measurements of the curvature of the Earth were carried out in the eighteenth century and Newton was proved correct.</p>
+
+<p>The Earth has an equatorial bulge, in other words. It is flattened at the poles. It is an "oblate spheroid" rather than a sphere. This means that the various diameters of the earth differ in length. The longest diameters are any of those that stretch from one point on the equator to an opposite point on the equator. The "equatorial diameter" is 12,755 kilometers (7,927 miles). The shortest diameter is from the North Pole to the South Pole and this "polar diameter" is 12,711 kilometers (7,900 miles).</p>
+
+<p>The difference between the longest and shortest diameters is 44 kilometers (27 miles), and that means that the "oblateness" of the Earth (its departure from true sphericity) is 44/12,755, or 0.0034. This amounts to 1/3 of 1 percent.</p>
+
+<p>To put it another way, on a flat surface, curvature is 0 per mile everywhere. On Earth's spherical surface, curvature is 0.000126 per mile everywhere (or 8 inches per mile). On Earth's oblate spheroidical surface, the curvature varies from 7.973 inches to the mile to 8.027 inches to the mile.</p>
+
+<p>The correction in going from spherical to oblate spheroidal is much smaller than going from flat to spherical. Therefore, although the notion of the Earth as sphere is wrong, strictly speaking, it is not <em>as</em> wrong as the notion of the Earth as flat.</p>
+
+<p>Even the oblate-spheroidal notion of the Earth is wrong, strictly speaking. In 1958, when the satellite <em>Vanguard 1</em> was put into orbit about the Earth, it was able to measure the local gravitational pull of the Earth—and therefore its shape—with unprecedented precision. It turned out that the equatorial bulge south of the equator was slightly bulgier than the bulge north of the equator, and that the South Pole sea level was slightly nearer the center of the Earth than the North Pole sea level was.</p>
+
+<p>There seemed no other way of describing this than by saying the Earth was pearshaped and at once many people decided that the Earth was nothing like a sphere but was shaped like a Bartlett pear dangling in space. Actually, the pearlike deviation from oblate-spheroid perfect was a matter of yards rather than miles and the adjustment of curvature was in the millionths of an inch per mile.</p>
+
+<p>In short, my English Lit friend, living in a mental world of absolute rights and wrongs, may be imagining that because all theories are <em>wrong</em>, the Earth may be thought spherical now, but cubical next century, and a hollow icosahedron the next, and a doughnut shape the one after.</p>
+
+<p>What actually happens is that once scientists get hold of a good concept they gradually refine and extend if with a greater and greater subtlety as their instruments of measurement improve. Theories are not so much wrong as incomplete.</p>
+</div>
+
+<div class="section">
+<p>This can be pointed out in many other cases than just the shape of the Earth. Even when a new theory seems to represent a revolution, it usually arises out of small refinements. If something more than a small refinement were needed, then the old theory would never have endured.</p>
+
+<p>Copernicus switched from an Earth-centered planetary system to a Sun-centered one. In doing so, he switched from something that was obvious to something that was apparently ridiculous. However, it was a matter of finding better ways of calculating the motion of the planets in the sky and, eventually, the geocentric theory was just left behind. It was precisely because the old theory gave results that were fairly good by the measurement standards of the time that kept it in being so long.</p>
+
+<p>Again, it is because the geological formations of the Earth change <em>so</em> slowly and the living things upon it evolve <em>so</em> slowly that it seemed reasonable at first to suppose that there was <em>no</em> change and that Earth and life always existed as they do today. If that were so, it would make no difference whether Earth and life were billions of years old or thousands. Thousands were easier to grasp.</p>
+
+<p>But when careful observation showed that Earth and life were changing at a rate that was very tiny but <em>not</em> zero, then it became clear that Earth and life had to be very old. Modern geology came into being, and so did the notion of biological evolution.</p>
+
+<p>If the rate of change were more rapid, geology and evolution would have reached their modern state in ancient times. It is only because the difference between the rate of change in a static Universe and the rate of change in an evolutionary one is that between zero and very nearly zero that the creationists can continue propagating their folly.</p>
+
+<p>Again, how about the two great theories of the twentieth century; relativity and quantum mechanics?<p>
+
+<p>Newton's theories of motion and gravitation were very close to right, and they would have been absolutely right if only the speed of light were infinite. However, the speed of light is finite, and that had to be taken into account in Einstein's relativistic equations, which were an extension and refinement of Newton's equations.</p>
+
+<p>You might say that the difference between infinite and finite is itself infinite, so why didn't Newton's equations fall to the ground at once? Let's put it another way, and ask how long it takes light to travel over a distance of a meter.</p>
+
+<p>If light traveled at infinite speed, it would take light 0 seconds to travel a meter. At the speed at which light actually travels, however, it takes it 0.0000000033 seconds. It is that difference between 0 and 0.0000000033 that Einstein corrected for.</p>
+
+<p>Conceptually, the correction was as important as the correction of Earth's curvature from 0 to 8 inches per mile was. Speeding subatomic particles wouldn't behave the way they do without the correction, nor would particle accelerators work the way they do, nor nuclear bombs explode, nor the stars shine. Nevertheless, it was a tiny correction and it is no wonder that Newton, in his time, could not allow for it, since he was limited in his observations to speeds and distances over which the correction was insignificant.</p>
+
+<p>Again, where the prequantum view of physics fell short was that it didn't allow for the "graininess" of the Universe. All forms of energy had been thought to be continuous and to be capable of division into indefinitely smaller and smaller quantities.</p>
+
+<p>This turned out to be not so. Energy comes in quanta, the size of which is dependent upon something called Planck's constant. If Planck's constant were equal to 0 erg-seconds, then energy would be continuous, and there would be no grain to the Universe. Planck's constant, however, is equal to 0.000000000000000000000000066 erg-seconds. That is indeed a tiny deviation from zero, so tiny that ordinary questions of energy in everyday life need not concern themselves with it. When, however, you deal with subatomic particles, the graininess is sufficiently large, in comparison, to make it impossible to deal with them without taking quantum considerations into account.</p>
+</div>
+
+<div class="section">
+<p>Since the refinements in theory grow smaller and smaller, even quite ancient theories must have been sufficiently right to allow advances to be made; advances that were not wiped out by subsequent refinements.</p>
+
+<p>The Greeks introduced the notion of latitude and longitude, for instance, and made reasonable maps of the Mediterranean basin even without taking sphericity into account, and we still use latitude and longitude today.</p>
+
+<p>The Sumerians were probably the first to establish the principle that planetary movements in the sky exhibit regularity and can be predicted, and they proceeded to work out ways of doing so even though they assumed the Earth to be the center of the Universe. Their measurements have been enormously refined but the principle remains.</p>
+
+<p>Newton's theory of gravitation, while incomplete over vast distances and enormous speeds, is perfectly suitable for the Solar System. Halley's Comet appears punctually as Newton's theory of gravitation and laws of motion predict. All of rocketry is based on Newton, and <em>Voyager II</em> reached Uranus within a second of the predicted time. None of these things were outlawed by relativity.</p>
+
+<p>In the nineteenth century, before quantum theory was dreamed of, the laws of thermodynamics were established, including the conservation of energy as first law, and the inevitable increase of entropy as the second law. Certain other conservation laws such as those of momentum, angular momentum, and electric charge were also established. So were Maxwell's laws of electromagnetism. All remained firmly entrenched even after quantum theory came in.</p>
+
+<p>Naturally, the theories we now have might be considered wrong in the simplistic sense of my English Lit correspondent, but in a much truer and subtler sense, they need only be considered incomplete.</p>
+
+<p>For instance, quantum theory has produced something called "quantum weirdness" which brings into serious question the very nature of reality and which produces philosophical conundrums that physicists simply can't seem to agree upon. It may be that we have reached a point where the human brain can no longer grasp matters, or it may be that quantum theory is incomplete and that once it is properly extended, all the "weirdness" will disappear.</p>
+
+<p>Again, quantum theory and relativity seem to be independent of each other, so that while quantum theory makes it seem possible that three of the four known interactions can be combined into one mathematical system, gravitation—the realm of relativity—as yet seems intransigent.</p>
+
+<p>If quantum theory and relativity can be combined, a true "unified field theory" may become possible.</p>
+
+<p>If all this is done, however, it would be a still finer refinement that would affect the edges of the known—the nature of the big bang and the creation of the Universe, the properties at the center of black holes, some subtle points about the evolution of galaxies and supernovas, and so on.</p>
+
+<p>Virtually all that we know today, however, would remain untouched and when I say I am glad that I live in a century when the Universe is essentially understood, I think I am justified.</p>

+Title: The Weaver of Worlds
+
+In a realm beyond the stars we know, lived an ancient being known only as the Weaver. It did not have a body of flesh, nor a voice that echoed in the air, but its existence was the loom upon which realities were spun. Each thread was a possibility, shimmering with colors unseen by mortal eyes – the crimson of a dying star, the silver of a silent thought, the emerald of a world teeming with life.
+
+One day, a young, ambitious star-spirit, Lyra, approached the Weaver. "Great Weaver," she pulsed, her light flickering with eagerness, "grant me a world of my own to shape, a tapestry of my own design!"

+The Weaver, in its timeless way, offered Lyra a single, plain thread, the color of unformed dust. "All worlds begin thus," resonated the Weaver, not in sound, but in understanding that bloomed in Lyra's core. "The pattern is not in the grandeur you impose, but in the care with which you weave what is given."
+
+Lyra was disappointed. She had imagined vibrant threads of power, fate, and instant creation. She took the dusty thread and began to weave, her early patterns clumsy and filled with frustration. She tried to force the thread into shapes of mighty empires and dazzling suns, but it remained dull and lifeless.
+
+Watching from afar, a comet, old and scarred from countless journeys, whispered to Lyra, "The Weaver's threads respond not to force, but to harmony. Seek the music within the dust."
+
+Lyra, humbled, held the thread and listened. She felt the faint vibrations of ancient cosmic songs, the echoes of births and deaths of realities long past. She began to weave again, not with ambition, but with attention, following the subtle pulls and flows within the thread itself. Slowly, miraculously, the dusty thread began to glow. Tiny specks of light, like nascent stars, appeared. A soft blue of nascent oceans, a gentle green of budding life, emerged not from Lyra's command, but from her partnership with the thread.
+
+She understood then that the Weaver did not grant worlds, but the potential for worlds. The beauty was not in the pre-ordained design, but in the dance of creation between the weaver and the eternally unfolding thread of what-is-to-be, guided by the wisdom of what-has-been. Her world, when it finally bloomed, was not the one she had first imagined, but it was far more wondrous, for it was a world born of listening, not just of making.

+When we look more deeply at this question, we can see that the apparent separation between observer and observed is actually an illusion. Our consciousness is not separate from the phenomenon we're examining.
+
+This situation invites us to consider not just the practical implications, but also the deeper patterns that connect these events to larger cycles of change and transformation.
+
+The challenge we face is not merely technological but existential: what does it mean to be human in an age where our creations begin to mirror our own capabilities?

+Title: The Nature of True Freedom
+
+We seek freedom, but what is this freedom we desire? Is it the liberty to do as one wishes, to pursue ambition, to accumulate, to express oneself without hindrance? This is what the world often calls freedom. But look closely. Is the pursuit of ambition not a form of bondage to success or failure, to recognition or obscurity? Is the accumulation of things not a tie to the material, a source of anxiety over loss? Is unhindered self-expression, if born from a self that is conditioned, merely the expression of that conditioning?
+
+True freedom, perhaps, lies not in the expansion of the self, but in the understanding of the self. The self, the 'me', is a construct of memory, of experience, of cultural and societal conditioning, of fears and desires. It is a bundle of conclusions. To be free from this self is not to destroy it in an act of will, for the entity that seeks to destroy is still part of that self. Rather, freedom comes from observing this self without judgment, without condemnation or justification.
+
+Observe your anger, your jealousy, your fear. Do not say 'I must not be angry,' for that is another form of conflict, of division within. Simply observe it as you would observe a cloud in the sky. See its structure, its movement, its arising and its passing. In this choiceless awareness, the nature of that which is observed begins to reveal itself.
+
+Freedom is not an end, a goal to be achieved in the future. It is in the very act of seeing, in the immediate perception of 'what is'. When the mind is no longer escaping from the actual, from the present, through ideals, through beliefs, through the pursuit of pleasure or the avoidance of pain, then there is a possibility of a different kind of freedom. This freedom is not from something, but a state of being in which the conditioning has been understood and therefore has fallen away. It is to be a light to oneself, not a follower of any authority, including the authority of one's own past experiences. This requires immense attention, a discipline that is not suppression but an active, alert observation from moment to moment.

+Title: Observation Without the Observer
+
+We are accustomed to thinking of an observer and the observed. 'I' see the tree. 'I' feel the anger. 'I' experience the joy. This division between the thinker and the thought, the experiencer and the experience, is the root of much conflict, both inner and outer. The observer is the past – the accumulation of memories, prejudices, conclusions – and this past is always interpreting, judging, shaping the present. So, what we see is not the thing as it is, but the thing as colored by our conditioning.
+
+Is it possible to observe without this observer? To see the tree without the word 'tree', without all the botanical knowledge or the aesthetic judgments that immediately arise? To feel anger without saying 'I am angry,' and thus identifying with it and either suppressing or expressing it? This means an observation in which the centre, the 'me', is absent.
+
+When there is such observation, there is no evaluation, no comparison, no condemnation or justification. There is only 'what is'. This state of seeing is a state of learning. Not accumulating knowledge, which is of the past, but learning in the sense of a direct perception of the truth of the moment.
+
+Consider conflict. If I am in conflict, and I try to resolve it, the 'I' that is trying to resolve is itself the product of conflict, of duality. So, the effort to resolve often creates further conflict. But if there is an observation of the conflict without the observer who wants to escape it, change it, or overcome it, then the conflict itself reveals its whole nature. In that direct perception, is there conflict?
+
+This is not a mystical state or something to be achieved through practice or technique. Practices and techniques imply a goal, a future, and therefore a continuity of the observer who is practicing. It is rather an immediate awareness, a seeing of the falseness of the division between the observer and the observed. When the thought 'I am suffering' is seen not as a separate entity evaluating a state, but as the suffering itself, then the energy that was consumed in division, in resistance, in trying to escape, is wholly present. In that total attention, that which we call suffering may undergo a radical transformation. The mind becomes extraordinarily quiet, not through enforcement, but because the sources of its agitation – the fragmentation created by the observer – are understood.

+Title: On Virtue and the Inner Citadel
+
+Marcus Aurelius often spoke of the 'inner citadel,' a fortress of the mind that, if properly fortified with reason and virtue, could remain impervious to the chaos and misfortunes of the external world. This concept, central to Stoicism, posits that true well-being (eudaimonia) arises not from favorable circumstances, but from one's own character and responses.
+
+Consider the nature of virtue. Is it a collection of rules, or a state of being? For Socrates, as Plato portrayed him, virtue was knowledge – specifically, the knowledge of good and evil. To truly know the good was to do the good, as no one willingly chooses what they know to be harmful to their soul. This implies that wrongdoing stems from ignorance. If one could truly understand the nature of justice, courage, temperance, and wisdom, one would naturally act in accordance with them.
+
+Aurelius extended this by emphasizing the practical application of these virtues in daily life. The 'Meditations' are a testament to this ongoing effort: to meet adversity with courage, injustice with fairness (or at least understanding), temptation with temperance, and complex situations with wisdom. The inner citadel is built by consistently choosing rational and virtuous responses over passionate, fearful, or selfish ones.
+
+This is not a call to suppress emotion, but to understand it and not be ruled by it. The philosophical path is one of constant self-examination and alignment with nature – both our own rational nature and the rational order of the cosmos. The strength of the inner citadel, therefore, is not in its walls, but in the character of its inhabitant.

+CRITO
+
+by Plato
+
+
+
+
+Translated by Benjamin Jowett
+
+
+
+
+INTRODUCTION.
+
+The Crito seems intended to exhibit the character of Socrates in one light
+only, not as the philosopher, fulfilling a divine mission and trusting in
+the will of heaven, but simply as the good citizen, who having been
+unjustly condemned is willing to give up his life in obedience to the laws
+of the state...
+
+The days of Socrates are drawing to a close; the fatal ship has been seen
+off Sunium, as he is informed by his aged friend and contemporary Crito,
+who visits him before the dawn has broken; he himself has been warned in a
+dream that on the third day he must depart.  Time is precious, and Crito
+has come early in order to gain his consent to a plan of escape.  This can
+be easily accomplished by his friends, who will incur no danger in making
+the attempt to save him, but will be disgraced for ever if they allow him
+to perish.  He should think of his duty to his children, and not play into
+the hands of his enemies.  Money is already provided by Crito as well as by
+Simmias and others, and he will have no difficulty in finding friends in
+Thessaly and other places.
+
+Socrates is afraid that Crito is but pressing upon him the opinions of the
+many:  whereas, all his life long he has followed the dictates of reason
+only and the opinion of the one wise or skilled man.  There was a time when
+Crito himself had allowed the propriety of this.  And although some one
+will say 'the many can kill us,' that makes no difference; but a good life,
+in other words, a just and honourable life, is alone to be valued.  All
+considerations of loss of reputation or injury to his children should be
+dismissed:  the only question is whether he would be right in attempting to
+escape.  Crito, who is a disinterested person not having the fear of death
+before his eyes, shall answer this for him.  Before he was condemned they
+had often held discussions, in which they agreed that no man should either
+do evil, or return evil for evil, or betray the right.  Are these
+principles to be altered because the circumstances of Socrates are altered?
+Crito admits that they remain the same.  Then is his escape consistent with
+the maintenance of them?  To this Crito is unable or unwilling to reply.
+
+Socrates proceeds:--Suppose the Laws of Athens to come and remonstrate with
+him:  they will ask 'Why does he seek to overturn them?' and if he replies,
+'they have injured him,' will not the Laws answer, 'Yes, but was that the
+agreement?  Has he any objection to make to them which would justify him in
+overturning them?  Was he not brought into the world and educated by their
+help, and are they not his parents?  He might have left Athens and gone
+where he pleased, but he has lived there for seventy years more constantly
+than any other citizen.'  Thus he has clearly shown that he acknowledged
+the agreement, which he cannot now break without dishonour to himself and
+danger to his friends.  Even in the course of the trial he might have
+proposed exile as the penalty, but then he declared that he preferred death
+to exile.  And whither will he direct his footsteps?  In any well-ordered
+state the Laws will consider him as an enemy.  Possibly in a land of
+misrule like Thessaly he may be welcomed at first, and the unseemly
+narrative of his escape will be regarded by the inhabitants as an amusing
+tale.  But if he offends them he will have to learn another sort of lesson.
+Will he continue to give lectures in virtue?  That would hardly be decent.
+And how will his children be the gainers if he takes them into Thessaly,
+and deprives them of Athenian citizenship?  Or if he leaves them behind,
+does he expect that they will be better taken care of by his friends
+because he is in Thessaly?  Will not true friends care for them equally
+whether he is alive or dead?
+
+Finally, they exhort him to think of justice first, and of life and
+children afterwards.  He may now depart in peace and innocence, a sufferer
+and not a doer of evil.  But if he breaks agreements, and returns evil for
+evil, they will be angry with him while he lives; and their brethren the
+Laws of the world below will receive him as an enemy.  Such is the mystic
+voice which is always murmuring in his ears.
+
+That Socrates was not a good citizen was a charge made against him during
+his lifetime, which has been often repeated in later ages.  The crimes of
+Alcibiades, Critias, and Charmides, who had been his pupils, were still
+recent in the memory of the now restored democracy.  The fact that he had
+been neutral in the death-struggle of Athens was not likely to conciliate
+popular good-will.  Plato, writing probably in the next generation,
+undertakes the defence of his friend and master in this particular, not to
+the Athenians of his day, but to posterity and the world at large.
+
+Whether such an incident ever really occurred as the visit of Crito and the
+proposal of escape is uncertain:  Plato could easily have invented far more
+than that (Phaedr.); and in the selection of Crito, the aged friend, as the
+fittest person to make the proposal to Socrates, we seem to recognize the
+hand of the artist.  Whether any one who has been subjected by the laws of
+his country to an unjust judgment is right in attempting to escape, is a
+thesis about which casuists might disagree.  Shelley (Prose Works) is of
+opinion that Socrates 'did well to die,' but not for the 'sophistical'
+reasons which Plato has put into his mouth.  And there would be no
+difficulty in arguing that Socrates should have lived and preferred to a
+glorious death the good which he might still be able to perform.  'A
+rhetorician would have had much to say upon that point.'  It may be
+observed however that Plato never intended to answer the question of
+casuistry, but only to exhibit the ideal of patient virtue which refuses to
+do the least evil in order to avoid the greatest, and to show his master
+maintaining in death the opinions which he had professed in his life.  Not
+'the world,' but the 'one wise man,' is still the paradox of Socrates in
+his last hours.  He must be guided by reason, although her conclusions may
+be fatal to him.  The remarkable sentiment that the wicked can do neither
+good nor evil is true, if taken in the sense, which he means, of moral
+evil; in his own words, 'they cannot make a man wise or foolish.'
+
+This little dialogue is a perfect piece of dialectic, in which granting the
+'common principle,' there is no escaping from the conclusion.  It is
+anticipated at the beginning by the dream of Socrates and the parody of
+Homer.  The personification of the Laws, and of their brethren the Laws in
+the world below, is one of the noblest and boldest figures of speech which
+occur in Plato.

+
+PERSONS OF THE DIALOGUE:  Socrates, Crito.
+
+SCENE:  The Prison of Socrates.
+
+
+SOCRATES:  Why have you come at this hour, Crito? it must be quite early.
+
+CRITO:  Yes, certainly.
+
+SOCRATES:  What is the exact time?
+
+CRITO:  The dawn is breaking.
+
+SOCRATES:  I wonder that the keeper of the prison would let you in.
+
+CRITO:  He knows me because I often come, Socrates; moreover.  I have done
+him a kindness.
+
+SOCRATES:  And are you only just arrived?
+
+CRITO:  No, I came some time ago.
+
+SOCRATES:  Then why did you sit and say nothing, instead of at once
+awakening me?
+
+CRITO:  I should not have liked myself, Socrates, to be in such great
+trouble and unrest as you are--indeed I should not:  I have been watching
+with amazement your peaceful slumbers; and for that reason I did not awake
+you, because I wished to minimize the pain.  I have always thought you to
+be of a happy disposition; but never did I see anything like the easy,
+tranquil manner in which you bear this calamity.
+
+SOCRATES:  Why, Crito, when a man has reached my age he ought not to be
+repining at the approach of death.
+
+CRITO:  And yet other old men find themselves in similar misfortunes, and
+age does not prevent them from repining.
+
+SOCRATES:  That is true.  But you have not told me why you come at this
+early hour.
+
+CRITO:  I come to bring you a message which is sad and painful; not, as I
+believe, to yourself, but to all of us who are your friends, and saddest of
+all to me.
+
+SOCRATES:  What?  Has the ship come from Delos, on the arrival of which I
+am to die?
+
+CRITO:  No, the ship has not actually arrived, but she will probably be
+here to-day, as persons who have come from Sunium tell me that they have
+left her there; and therefore to-morrow, Socrates, will be the last day of
+your life.
+
+SOCRATES:  Very well, Crito; if such is the will of God, I am willing; but
+my belief is that there will be a delay of a day.
+
+CRITO:  Why do you think so?
+
+SOCRATES:  I will tell you.  I am to die on the day after the arrival of
+the ship?
+
+CRITO:  Yes; that is what the authorities say.
+
+SOCRATES:  But I do not think that the ship will be here until to-morrow;
+this I infer from a vision which I had last night, or rather only just now,
+when you fortunately allowed me to sleep.
+
+CRITO:  And what was the nature of the vision?
+
+SOCRATES:  There appeared to me the likeness of a woman, fair and comely,
+clothed in bright raiment, who called to me and said:  O Socrates,
+
+'The third day hence to fertile Phthia shalt thou go.'  (Homer, Il.)
+
+CRITO:  What a singular dream, Socrates!
+
+SOCRATES:  There can be no doubt about the meaning, Crito, I think.
+
+CRITO:  Yes; the meaning is only too clear.  But, oh! my beloved Socrates,
+let me entreat you once more to take my advice and escape.  For if you die
+I shall not only lose a friend who can never be replaced, but there is
+another evil:  people who do not know you and me will believe that I might
+have saved you if I had been willing to give money, but that I did not
+care.  Now, can there be a worse disgrace than this--that I should be
+thought to value money more than the life of a friend?  For the many will
+not be persuaded that I wanted you to escape, and that you refused.
+
+SOCRATES:  But why, my dear Crito, should we care about the opinion of the
+many?  Good men, and they are the only persons who are worth considering,
+will think of these things truly as they occurred.
+
+CRITO:  But you see, Socrates, that the opinion of the many must be
+regarded, for what is now happening shows that they can do the greatest
+evil to any one who has lost their good opinion.
+
+SOCRATES:  I only wish it were so, Crito; and that the many could do the
+greatest evil; for then they would also be able to do the greatest good--
+and what a fine thing this would be!  But in reality they can do neither;
+for they cannot make a man either wise or foolish; and whatever they do is
+the result of chance.
+
+CRITO:  Well, I will not dispute with you; but please to tell me, Socrates,
+whether you are not acting out of regard to me and your other friends:  are
+you not afraid that if you escape from prison we may get into trouble with
+the informers for having stolen you away, and lose either the whole or a
+great part of our property; or that even a worse evil may happen to us?
+Now, if you fear on our account, be at ease; for in order to save you, we
+ought surely to run this, or even a greater risk; be persuaded, then, and
+do as I say.
+
+SOCRATES:  Yes, Crito, that is one fear which you mention, but by no means
+the only one.
+
+CRITO:  Fear not--there are persons who are willing to get you out of
+prison at no great cost; and as for the informers they are far from being
+exorbitant in their demands--a little money will satisfy them.  My means,
+which are certainly ample, are at your service, and if you have a scruple
+about spending all mine, here are strangers who will give you the use of
+theirs; and one of them, Simmias the Theban, has brought a large sum of
+money for this very purpose; and Cebes and many others are prepared to
+spend their money in helping you to escape.  I say, therefore, do not
+hesitate on our account, and do not say, as you did in the court (compare
+Apol.), that you will have a difficulty in knowing what to do with yourself
+anywhere else.  For men will love you in other places to which you may go,
+and not in Athens only; there are friends of mine in Thessaly, if you like
+to go to them, who will value and protect you, and no Thessalian will give
+you any trouble.  Nor can I think that you are at all justified, Socrates,
+in betraying your own life when you might be saved; in acting thus you are
+playing into the hands of your enemies, who are hurrying on your
+destruction.  And further I should say that you are deserting your own
+children; for you might bring them up and educate them; instead of which
+you go away and leave them, and they will have to take their chance; and if
+they do not meet with the usual fate of orphans, there will be small thanks
+to you.  No man should bring children into the world who is unwilling to
+persevere to the end in their nurture and education.  But you appear to be
+choosing the easier part, not the better and manlier, which would have been
+more becoming in one who professes to care for virtue in all his actions,
+like yourself.  And indeed, I am ashamed not only of you, but of us who are
+your friends, when I reflect that the whole business will be attributed
+entirely to our want of courage.  The trial need never have come on, or
+might have been managed differently; and this last act, or crowning folly,
+will seem to have occurred through our negligence and cowardice, who might
+have saved you, if we had been good for anything; and you might have saved
+yourself, for there was no difficulty at all.  See now, Socrates, how sad
+and discreditable are the consequences, both to us and you.  Make up your
+mind then, or rather have your mind already made up, for the time of
+deliberation is over, and there is only one thing to be done, which must be
+done this very night, and if we delay at all will be no longer practicable
+or possible; I beseech you therefore, Socrates, be persuaded by me, and do
+as I say.
+
+SOCRATES:  Dear Crito, your zeal is invaluable, if a right one; but if
+wrong, the greater the zeal the greater the danger; and therefore we ought
+to consider whether I shall or shall not do as you say.  For I am and
+always have been one of those natures who must be guided by reason,
+whatever the reason may be which upon reflection appears to me to be the
+best; and now that this chance has befallen me, I cannot repudiate my own
+words:  the principles which I have hitherto honoured and revered I still
+honour, and unless we can at once find other and better principles, I am
+certain not to agree with you; no, not even if the power of the multitude
+could inflict many more imprisonments, confiscations, deaths, frightening
+us like children with hobgoblin terrors (compare Apol.).  What will be the
+fairest way of considering the question?  Shall I return to your old
+argument about the opinions of men?--we were saying that some of them are
+to be regarded, and others not.  Now were we right in maintaining this
+before I was condemned?  And has the argument which was once good now
+proved to be talk for the sake of talking--mere childish nonsense?  That is
+what I want to consider with your help, Crito:--whether, under my present
+circumstances, the argument appears to be in any way different or not; and
+is to be allowed by me or disallowed.  That argument, which, as I believe,
+is maintained by many persons of authority, was to the effect, as I was
+saying, that the opinions of some men are to be regarded, and of other men
+not to be regarded.  Now you, Crito, are not going to die to-morrow--at
+least, there is no human probability of this, and therefore you are
+disinterested and not liable to be deceived by the circumstances in which
+you are placed.  Tell me then, whether I am right in saying that some
+opinions, and the opinions of some men only, are to be valued, and that
+other opinions, and the opinions of other men, are not to be valued.  I ask
+you whether I was right in maintaining this?
+
+CRITO:  Certainly.
+
+SOCRATES:  The good are to be regarded, and not the bad?
+
+CRITO:  Yes.
+
+SOCRATES:  And the opinions of the wise are good, and the opinions of the
+unwise are evil?
+
+CRITO:  Certainly.
+
+SOCRATES:  And what was said about another matter?  Is the pupil who
+devotes himself to the practice of gymnastics supposed to attend to the
+praise and blame and opinion of every man, or of one man only--his
+physician or trainer, whoever he may be?
+
+CRITO:  Of one man only.
+
+SOCRATES:  And he ought to fear the censure and welcome the praise of that
+one only, and not of the many?
+
+CRITO:  Clearly so.
+
+SOCRATES:  And he ought to act and train, and eat and drink in the way
+which seems good to his single master who has understanding, rather than
+according to the opinion of all other men put together?
+
+CRITO:  True.
+
+SOCRATES:  And if he disobeys and disregards the opinion and approval of
+the one, and regards the opinion of the many who have no understanding,
+will he not suffer evil?
+
+CRITO:  Certainly he will.
+
+SOCRATES:  And what will the evil be, whither tending and what affecting,
+in the disobedient person?
+
+CRITO:  Clearly, affecting the body; that is what is destroyed by the evil.
+
+SOCRATES:  Very good; and is not this true, Crito, of other things which we
+need not separately enumerate?  In questions of just and unjust, fair and
+foul, good and evil, which are the subjects of our present consultation,
+ought we to follow the opinion of the many and to fear them; or the opinion
+of the one man who has understanding? ought we not to fear and reverence
+him more than all the rest of the world:  and if we desert him shall we not
+destroy and injure that principle in us which may be assumed to be improved
+by justice and deteriorated by injustice;--there is such a principle?
+
+CRITO:  Certainly there is, Socrates.
+
+SOCRATES:  Take a parallel instance:--if, acting under the advice of those
+who have no understanding, we destroy that which is improved by health and
+is deteriorated by disease, would life be worth having?  And that which has
+been destroyed is--the body?
+
+CRITO:  Yes.
+
+SOCRATES:  Could we live, having an evil and corrupted body?
+
+CRITO:  Certainly not.
+
+SOCRATES:  And will life be worth having, if that higher part of man be
+destroyed, which is improved by justice and depraved by injustice?  Do we
+suppose that principle, whatever it may be in man, which has to do with
+justice and injustice, to be inferior to the body?
+
+CRITO:  Certainly not.
+
+SOCRATES:  More honourable than the body?
+
+CRITO:  Far more.
+
+SOCRATES:  Then, my friend, we must not regard what the many say of us:
+but what he, the one man who has understanding of just and unjust, will
+say, and what the truth will say.  And therefore you begin in error when
+you advise that we should regard the opinion of the many about just and
+unjust, good and evil, honorable and dishonorable.--'Well,' some one will
+say, 'but the many can kill us.'
+
+CRITO:  Yes, Socrates; that will clearly be the answer.
+
+SOCRATES:  And it is true; but still I find with surprise that the old
+argument is unshaken as ever.  And I should like to know whether I may say
+the same of another proposition--that not life, but a good life, is to be
+chiefly valued?
+
+CRITO:  Yes, that also remains unshaken.
+
+SOCRATES:  And a good life is equivalent to a just and honorable one--that
+holds also?
+
+CRITO:  Yes, it does.
+
+SOCRATES:  From these premisses I proceed to argue the question whether I
+ought or ought not to try and escape without the consent of the Athenians:
+and if I am clearly right in escaping, then I will make the attempt; but if
+not, I will abstain.  The other considerations which you mention, of money
+and loss of character and the duty of educating one's children, are, I
+fear, only the doctrines of the multitude, who would be as ready to restore
+people to life, if they were able, as they are to put them to death--and
+with as little reason.  But now, since the argument has thus far prevailed,
+the only question which remains to be considered is, whether we shall do
+rightly either in escaping or in suffering others to aid in our escape and
+paying them in money and thanks, or whether in reality we shall not do
+rightly; and if the latter, then death or any other calamity which may
+ensue on my remaining here must not be allowed to enter into the
+calculation.
+
+CRITO:  I think that you are right, Socrates; how then shall we proceed?
+
+SOCRATES:  Let us consider the matter together, and do you either refute me
+if you can, and I will be convinced; or else cease, my dear friend, from
+repeating to me that I ought to escape against the wishes of the Athenians:
+for I highly value your attempts to persuade me to do so, but I may not be
+persuaded against my own better judgment.  And now please to consider my
+first position, and try how you can best answer me.
+
+CRITO:  I will.
+
+SOCRATES:  Are we to say that we are never intentionally to do wrong, or
+that in one way we ought and in another way we ought not to do wrong, or is
+doing wrong always evil and dishonorable, as I was just now saying, and as
+has been already acknowledged by us?  Are all our former admissions which
+were made within a few days to be thrown away?  And have we, at our age,
+been earnestly discoursing with one another all our life long only to
+discover that we are no better than children?  Or, in spite of the opinion
+of the many, and in spite of consequences whether better or worse, shall we
+insist on the truth of what was then said, that injustice is always an evil
+and dishonour to him who acts unjustly?  Shall we say so or not?
+
+CRITO:  Yes.
+
+SOCRATES:  Then we must do no wrong?
+
+CRITO:  Certainly not.
+
+SOCRATES:  Nor when injured injure in return, as the many imagine; for we
+must injure no one at all?  (E.g. compare Rep.)
+
+CRITO:  Clearly not.
+
+SOCRATES:  Again, Crito, may we do evil?
+
+CRITO:  Surely not, Socrates.
+
+SOCRATES:  And what of doing evil in return for evil, which is the morality
+of the many--is that just or not?
+
+CRITO:  Not just.
+
+SOCRATES:  For doing evil to another is the same as injuring him?
+
+CRITO:  Very true.
+
+SOCRATES:  Then we ought not to retaliate or render evil for evil to any
+one, whatever evil we may have suffered from him.  But I would have you
+consider, Crito, whether you really mean what you are saying.  For this
+opinion has never been held, and never will be held, by any considerable
+number of persons; and those who are agreed and those who are not agreed
+upon this point have no common ground, and can only despise one another
+when they see how widely they differ.  Tell me, then, whether you agree
+with and assent to my first principle, that neither injury nor retaliation
+nor warding off evil by evil is ever right.  And shall that be the premiss
+of our argument?  Or do you decline and dissent from this?  For so I have
+ever thought, and continue to think; but, if you are of another opinion,
+let me hear what you have to say.  If, however, you remain of the same mind
+as formerly, I will proceed to the next step.
+
+CRITO:  You may proceed, for I have not changed my mind.
+
+SOCRATES:  Then I will go on to the next point, which may be put in the
+form of a question:--Ought a man to do what he admits to be right, or ought
+he to betray the right?
+
+CRITO:  He ought to do what he thinks right.
+
+SOCRATES:  But if this is true, what is the application?  In leaving the
+prison against the will of the Athenians, do I wrong any? or rather do I
+not wrong those whom I ought least to wrong?  Do I not desert the
+principles which were acknowledged by us to be just--what do you say?
+
+CRITO:  I cannot tell, Socrates, for I do not know.
+
+SOCRATES:  Then consider the matter in this way:--Imagine that I am about
+to play truant (you may call the proceeding by any name which you like),
+and the laws and the government come and interrogate me:  'Tell us,
+Socrates,' they say; 'what are you about? are you not going by an act of
+yours to overturn us--the laws, and the whole state, as far as in you lies?
+Do you imagine that a state can subsist and not be overthrown, in which the
+decisions of law have no power, but are set aside and trampled upon by
+individuals?'  What will be our answer, Crito, to these and the like words?
+Any one, and especially a rhetorician, will have a good deal to say on
+behalf of the law which requires a sentence to be carried out.  He will
+argue that this law should not be set aside; and shall we reply, 'Yes; but
+the state has injured us and given an unjust sentence.'  Suppose I say
+that?
+
+CRITO:  Very good, Socrates.
+
+SOCRATES:  'And was that our agreement with you?' the law would answer; 'or
+were you to abide by the sentence of the state?'  And if I were to express
+my astonishment at their words, the law would probably add:  'Answer,
+Socrates, instead of opening your eyes--you are in the habit of asking and
+answering questions.  Tell us,--What complaint have you to make against us
+which justifies you in attempting to destroy us and the state?  In the
+first place did we not bring you into existence?  Your father married your
+mother by our aid and begat you.  Say whether you have any objection to
+urge against those of us who regulate marriage?'  None, I should reply.
+'Or against those of us who after birth regulate the nurture and education
+of children, in which you also were trained?  Were not the laws, which have
+the charge of education, right in commanding your father to train you in
+music and gymnastic?'  Right, I should reply.  'Well then, since you were
+brought into the world and nurtured and educated by us, can you deny in the
+first place that you are our child and slave, as your fathers were before
+you?  And if this is true you are not on equal terms with us; nor can you
+think that you have a right to do to us what we are doing to you.  Would
+you have any right to strike or revile or do any other evil to your father
+or your master, if you had one, because you have been struck or reviled by
+him, or received some other evil at his hands?--you would not say this?
+And because we think right to destroy you, do you think that you have any
+right to destroy us in return, and your country as far as in you lies?
+Will you, O professor of true virtue, pretend that you are justified in
+this?  Has a philosopher like you failed to discover that our country is
+more to be valued and higher and holier far than mother or father or any
+ancestor, and more to be regarded in the eyes of the gods and of men of
+understanding? also to be soothed, and gently and reverently entreated when
+angry, even more than a father, and either to be persuaded, or if not
+persuaded, to be obeyed?  And when we are punished by her, whether with
+imprisonment or stripes, the punishment is to be endured in silence; and if
+she lead us to wounds or death in battle, thither we follow as is right;
+neither may any one yield or retreat or leave his rank, but whether in
+battle or in a court of law, or in any other place, he must do what his
+city and his country order him; or he must change their view of what is
+just:  and if he may do no violence to his father or mother, much less may
+he do violence to his country.'  What answer shall we make to this, Crito?
+Do the laws speak truly, or do they not?
+
+CRITO:  I think that they do.
+
+SOCRATES:  Then the laws will say:  'Consider, Socrates, if we are speaking
+truly that in your present attempt you are going to do us an injury.  For,
+having brought you into the world, and nurtured and educated you, and given
+you and every other citizen a share in every good which we had to give, we
+further proclaim to any Athenian by the liberty which we allow him, that if
+he does not like us when he has become of age and has seen the ways of the
+city, and made our acquaintance, he may go where he pleases and take his
+goods with him.  None of us laws will forbid him or interfere with him.
+Any one who does not like us and the city, and who wants to emigrate to a
+colony or to any other city, may go where he likes, retaining his property.
+But he who has experience of the manner in which we order justice and
+administer the state, and still remains, has entered into an implied
+contract that he will do as we command him.  And he who disobeys us is, as
+we maintain, thrice wrong:  first, because in disobeying us he is
+disobeying his parents; secondly, because we are the authors of his
+education; thirdly, because he has made an agreement with us that he will
+duly obey our commands; and he neither obeys them nor convinces us that our
+commands are unjust; and we do not rudely impose them, but give him the
+alternative of obeying or convincing us;--that is what we offer, and he
+does neither.
+
+'These are the sort of accusations to which, as we were saying, you,
+Socrates, will be exposed if you accomplish your intentions; you, above all
+other Athenians.'  Suppose now I ask, why I rather than anybody else? they
+will justly retort upon me that I above all other men have acknowledged the
+agreement.  'There is clear proof,' they will say, 'Socrates, that we and
+the city were not displeasing to you.  Of all Athenians you have been the
+most constant resident in the city, which, as you never leave, you may be
+supposed to love (compare Phaedr.).  For you never went out of the city
+either to see the games, except once when you went to the Isthmus, or to
+any other place unless when you were on military service; nor did you
+travel as other men do.  Nor had you any curiosity to know other states or
+their laws:  your affections did not go beyond us and our state; we were
+your especial favourites, and you acquiesced in our government of you; and
+here in this city you begat your children, which is a proof of your
+satisfaction.  Moreover, you might in the course of the trial, if you had
+liked, have fixed the penalty at banishment; the state which refuses to let
+you go now would have let you go then.  But you pretended that you
+preferred death to exile (compare Apol.), and that you were not unwilling
+to die.  And now you have forgotten these fine sentiments, and pay no
+respect to us the laws, of whom you are the destroyer; and are doing what
+only a miserable slave would do, running away and turning your back upon
+the compacts and agreements which you made as a citizen.  And first of all
+answer this very question:  Are we right in saying that you agreed to be
+governed according to us in deed, and not in word only?  Is that true or
+not?'  How shall we answer, Crito?  Must we not assent?
+
+CRITO:  We cannot help it, Socrates.
+
+SOCRATES:  Then will they not say:  'You, Socrates, are breaking the
+covenants and agreements which you made with us at your leisure, not in any
+haste or under any compulsion or deception, but after you have had seventy
+years to think of them, during which time you were at liberty to leave the
+city, if we were not to your mind, or if our covenants appeared to you to
+be unfair.  You had your choice, and might have gone either to Lacedaemon
+or Crete, both which states are often praised by you for their good
+government, or to some other Hellenic or foreign state.  Whereas you, above
+all other Athenians, seemed to be so fond of the state, or, in other words,
+of us her laws (and who would care about a state which has no laws?), that
+you never stirred out of her; the halt, the blind, the maimed, were not
+more stationary in her than you were.  And now you run away and forsake
+your agreements.  Not so, Socrates, if you will take our advice; do not
+make yourself ridiculous by escaping out of the city.
+
+'For just consider, if you transgress and err in this sort of way, what
+good will you do either to yourself or to your friends?  That your friends
+will be driven into exile and deprived of citizenship, or will lose their
+property, is tolerably certain; and you yourself, if you fly to one of the
+neighbouring cities, as, for example, Thebes or Megara, both of which are
+well governed, will come to them as an enemy, Socrates, and their
+government will be against you, and all patriotic citizens will cast an
+evil eye upon you as a subverter of the laws, and you will confirm in the
+minds of the judges the justice of their own condemnation of you.  For he
+who is a corrupter of the laws is more than likely to be a corrupter of the
+young and foolish portion of mankind.  Will you then flee from well-ordered
+cities and virtuous men? and is existence worth having on these terms?  Or
+will you go to them without shame, and talk to them, Socrates?  And what
+will you say to them?  What you say here about virtue and justice and
+institutions and laws being the best things among men?  Would that be
+decent of you?  Surely not.  But if you go away from well-governed states
+to Crito's friends in Thessaly, where there is great disorder and licence,
+they will be charmed to hear the tale of your escape from prison, set off
+with ludicrous particulars of the manner in which you were wrapped in a
+goatskin or some other disguise, and metamorphosed as the manner is of
+runaways; but will there be no one to remind you that in your old age you
+were not ashamed to violate the most sacred laws from a miserable desire of
+a little more life?  Perhaps not, if you keep them in a good temper; but if
+they are out of temper you will hear many degrading things; you will live,
+but how?--as the flatterer of all men, and the servant of all men; and
+doing what?--eating and drinking in Thessaly, having gone abroad in order
+that you may get a dinner.  And where will be your fine sentiments about
+justice and virtue?  Say that you wish to live for the sake of your
+children--you want to bring them up and educate them--will you take them
+into Thessaly and deprive them of Athenian citizenship?  Is this the
+benefit which you will confer upon them?  Or are you under the impression
+that they will be better cared for and educated here if you are still
+alive, although absent from them; for your friends will take care of them?
+Do you fancy that if you are an inhabitant of Thessaly they will take care
+of them, and if you are an inhabitant of the other world that they will not
+take care of them?  Nay; but if they who call themselves friends are good
+for anything, they will--to be sure they will.
+
+'Listen, then, Socrates, to us who have brought you up.  Think not of life
+and children first, and of justice afterwards, but of justice first, that
+you may be justified before the princes of the world below.  For neither
+will you nor any that belong to you be happier or holier or juster in this
+life, or happier in another, if you do as Crito bids.  Now you depart in
+innocence, a sufferer and not a doer of evil; a victim, not of the laws,
+but of men.  But if you go forth, returning evil for evil, and injury for
+injury, breaking the covenants and agreements which you have made with us,
+and wronging those whom you ought least of all to wrong, that is to say,
+yourself, your friends, your country, and us, we shall be angry with you
+while you live, and our brethren, the laws in the world below, will receive
+you as an enemy; for they will know that you have done your best to destroy
+us.  Listen, then, to us and not to Crito.'
+
+This, dear Crito, is the voice which I seem to hear murmuring in my ears,
+like the sound of the flute in the ears of the mystic; that voice, I say,
+is humming in my ears, and prevents me from hearing any other.  And I know
+that anything more which you may say will be vain.  Yet speak, if you have
+anything to say.
+
+CRITO:  I have nothing to say, Socrates.
+
+SOCRATES:  Leave me then, Crito, to fulfil the will of God, and to follow
+whither he leads.

+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg™ electronic works in
+accordance with this agreement, and any volunteers associated with the
+production, promotion and distribution of Project Gutenberg™
+electronic works, harmless from all liability, costs and expenses,
+including legal fees, that arise directly or indirectly from any of
+the following which you do or cause to occur: (a) distribution of this
+or any Project Gutenberg™ work, (b) alteration, modification, or
+additions or deletions to any Project Gutenberg™ work, and (c) any
+Defect you cause.
+
+Section 2. Information about the Mission of Project Gutenberg™
+
+Project Gutenberg™ is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of
+computers including obsolete, old, middle-aged and new computers. It
+exists because of the efforts of hundreds of volunteers and donations
+from people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg™’s
+goals and ensuring that the Project Gutenberg™ collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg™ and future
+generations. To learn more about the Project Gutenberg Literary
+Archive Foundation and how your efforts and donations can help, see
+Sections 3 and 4 and the Foundation information page at www.gutenberg.org.
+
+Section 3. Information about the Project Gutenberg Literary Archive Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non-profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation’s EIN or federal tax identification
+number is 64-6221541. Contributions to the Project Gutenberg Literary
+Archive Foundation are tax deductible to the full extent permitted by
+U.S. federal laws and your state’s laws.
+
+The Foundation’s business office is located at 809 North 1500 West,
+Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up
+to date contact information can be found at the Foundation’s website
+and official page at www.gutenberg.org/contact
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg™ depends upon and cannot survive without widespread
+public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine-readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To SEND
+DONATIONS or determine the status of compliance for any particular state
+visit www.gutenberg.org/donate.
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations. To
+donate, please visit: www.gutenberg.org/donate.
+
+Section 5. General Information About Project Gutenberg™ electronic works
+
+Professor Michael S. Hart was the originator of the Project
+Gutenberg™ concept of a library of electronic works that could be
+freely shared with anyone. For forty years, he produced and
+distributed Project Gutenberg™ eBooks with only a loose network of
+volunteer support.
+
+Project Gutenberg™ eBooks are often created from several printed
+editions, all of which are confirmed as not protected by copyright in
+the U.S. unless a copyright notice is included. Thus, we do not
+necessarily keep eBooks in compliance with any particular paper
+edition.
+
+Most people start at our website which has the main PG search
+facility: www.gutenberg.org.
+
+This website includes information about Project Gutenberg™,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
