You couldn't changed history. But you could get it right to start with. Do something differently the FIRST time around. This whole business with seeking Slytherin's secrets... seemed an awful lot like the sort of thing where, years later, you would look back and say, 'And THAT was where it all started to go wrong.' And he would wish desperately for the ability to fall back through time and make a different choice. Wish granted. Now what?

Only a man exceedingly proud and vain," Dumbledore said quietly, as he turned back to the Floo roaring up again with green flames, "would believe that his heir should be like himself, rather than like who he wished that he could be.

Sometimes, when this flawed world seems unusually hateful, I wonder whether there might be some other place, far away, where I should have been. I cannot seem to imagine what that place might be, and if I can't even imagine it then how can I believe it exists? And yet the universe is so very, very wide, and perhaps it might exist anyway? But the stars are so very, very far away. It would take a long, long time to get there, even if I knew the way. And I wonder what I would dream about, if I slept for a long, long time...

For a hundred years or more, every textbook of psychology and psychotherapy has advised that some method of talking about distressing feelings can resolve them. However, as we’ve seen, the experience of trauma itself gets in the way of being able to do that. No matter how much insight and understanding we develop, the rational brain is basically impotent to talk the emotional brain out of its own reality. I am continually impressed by how difficult it is for people who have gone through the unspeakable to convey the essence of their experience. It is so much easier for them to talk about what has been done to them—to tell a story of victimization and revenge—than to notice, feel, and put into words the reality of their internal experience. Our scans had revealed how their dread persisted and could be triggered by multiple aspects of daily experience. They had not integrated their experience into the ongoing stream of their life. They continued to be “there” and did not know how to be “here”—fully alive in the present.

Mr. Malfoy is new to the business of having ideas, and so when he has one, he becomes proud of himself for having it. He has not yet had enough ideas to unflinchingly discard those that are beautiful in some aspects and impractical in others; he has not yet acquired confidence in his own ability to think of better ideas as he requires them. What we are seeing here is not Mr. Malfoy's best idea, I fear, but rather his only idea.

The methods of increasing the degree of truth in our beliefs are well known; they consist in hearing all sides, trying to ascertain all the relevant facts, controlling our own bias by discussion with people who have the opposite bias, and cultivating a readiness to discard any hypothesis which has proved inadequate.

But it is cute. It's such a boy thing to do. Drop dead. Aw, you say the most romantic things.

Note to self: Overthrow government of magical Britain at earliest convenience.

Without thinking about it at all, Harry stepped in front of Hermione. There was an intake of breath from behind him, and then a moment later Hermione brushed past and stepped in front of him. "Run, Harry!" she said. "Boys shouldn't have to be in danger.

For an instant Harry imagined his own Mum and Dad in Azkaban with the Dementors sucking out their life, draining away the happy memories of their love for him. Just for an instant, before his imagination blew a fuse and called an emergency shutdown and told him never to imagine that again.

a rationalist isn't ever certain of anything

Briefly stated, the true purpose of ancient philosophy was to discover a method whereby development of the rational nature could be accelerated instead of awaiting the slower processes of Nature.

I will remark, that it is a common misconception of Ravenclaws that all the smart children are Sorted there, leaving none for other Houses. This is not so; being Sorted to Ravenclaw indicates that you are driven by your desire to know things, which is not at all the same quality as being intelligent.

Something, somewhere, somewhen, must have happened differently... PETUNIA EVANS married Michael Verres, a Professor of Biochemistry at Oxford. HARRY JAMES POTTER-EVANS-VERRES grew up in a house filled to the brim with books. He once bit a math teacher who didn't know what a logarithm was. He's read Godel, Escher, Bach and Judgment Under Uncertainty: Heuristics and Biases and volume one of The Feynman Lectures on Physics. And despite what everyone who's met him seems to fear, he doesn't want to become the next Dark Lord. He was raised better than that. He wants to discover the laws of magic and become a god. HERMIONE GRANGER is doing better than him in every class except broomstick riding. DRACO MALFOY is exactly what you would expect an eleven-year-old boy to be like if Darth Vader were his doting father. PROFESSOR QUIRRELL is living his lifelong dream of teaching Defense Against the Dark Arts, or as he prefers to call his class, Battle Magic. His students are all wondering what's going to go wrong with the Defense Professor this time. DUMBLEDORE is either insane, or playing some vastly deeper game which involved setting fire to a chicken. DEPUTY HEADMISTRESS MINERVA MCGONAGALL needs to go off somewhere private and scream for a while. Presenting: HARRY POTTER AND THE METHODS OF RATIONALITY You ain't guessin' where this one's going.

You're so completely going to be in Slytherin." "I'm so completely going to be in Ravenclaw, thank you very much. I only want power so I can get books.

No..." said Professor Quirrell. "That is not why I am here. You have made no effort to hide your dislike for me, Miss Granger. I thank you for that lack of pretense, for I much prefer true hate to false love.

Harry's suspension of disbelief blew completely out the window. You're giving me a time machine to treat my sleep disorder. You're giving me a TIME MACHINE to treat my SLEEP DISORDER. YOU'RE GIVING ME A TIME MACHINE IN ORDER TO TREAT MY SLEEP DISORDER. "Ehehehehhheheh..." Harry's mouth said. He was now holding the necklace away from him as though it were a live bomb. Well, no, not as if it were a live bomb, that didn't begin to describe the severity of the situation. Harry held the necklace away from him as though it were a time machine.

There is no justice in the laws of nature, no term for fairness in the equations of motion. The Universe is neither evil, nor good, it simply does not care. The stars don't care, or the Sun, or the sky.

Sometimes Harry thought the deepest split in his personality wasn't anything to do with his dark side; rather it was the divide between the altruistic and forgiving Abstract Reasoning Harry, versus the frustrated and angry Harry In The Moment.

Sometimes we forget the most basic things, since it has been too long since we learned them. I realized I had done the same with my own lesson plan. You do not teach students to throw until you have taught them to fall. And I must not teach you to fight if you do not understand how to lose.

You will find ambiguity a great ally on your road to power. Give a sign of Slytherin on one day, and contradict it with a sign of Gryffindor the next; and the Slytherins will be enabled to believe what they wish, while the Gryffindors argue themselves into supporting you as well. So long as there is uncertainty, people can believe whatever seems to be to their own advantage. And so long as you appear strong, so long as you appear to be winning, their instincts will tell them that their advantage lies with you. Walk always in the shadow, and light and darkness both will follow.

The true method of discovery is like the flight of an aeroplane. It starts from the ground of particular observation; it makes a flight in the thin air of imaginative generalization; and it again lands for renewed observation rendered acute by rational interpretation.

When we look at others we see personality traits that explain their behaviour, but when we look at ourselves we see circumstances that explain our behaviour. People's stories make internal sense to them, from the inside, but we don't see people's histories trailing behind them in the air. We only see them in one situation, and we don't see what they would be like in a different situation. So the fundamental attribution error is that we explain by permanent, enduring traits what would be better explained by circumstance and context.

Most Muggles lived in a world defined by the limits of what you could do with cars and telephones. Even though Muggle physics explicitly permitted possibilities like molecular nanotechnology or the Penrose process for extracting energy from black holes, most people filed that away in the same section of their brain that stored fairy tales and history books, well away from their personal realities: Long ago and far away, ever so long ago.

Then you get the wrong answer and you can't go to the Moon that way! Nature isn't a person, you can't trick them into believing something else, if you try to tell the Moon it's made of cheese you can argue for days and it won't change the Moon! What you're talking about is rationalization, like starting with a sheet of paper, moving straight down to the bottom line, using ink to write 'and therefore, the Moon is made of cheese', and then moving back up to write all sorts of clever arguments above. But either the Moon is made of cheese or it isn't. The moment you wrote the bottom line, it was already true or already false. Whether or not the whole sheet of paper ends up with the right conclusion or the wrong conclusion is fixed the instant you write down the bottom line.

Yes, I'm a materialist. I'm willing to be shown wrong, but that has not happened — yet. And I admit that the reason I'm unable to accept the claims of psychic, occult, and/or supernatural wonders is because I'm locked into a world-view that demands evidence rather than blind faith, a view that insists upon the replication of all experiments — particularly those that appear to show violations of a rational world — and a view which requires open examination of the methods used to carry out those experiments.

Lies propagate, that's what I'm saying. You've got to tell more lies to cover them up, lie about every fact that's connected to the first lie. And if you kept on lying, and you kept on trying to cover it up, sooner or later you'd even have to start lying about the general laws of thought. Like, someone is selling you some kind of alternative medicine that doesn't work, and any double-blind experimental study will confirm that it doesn't work. So if someone wants to go on defending the lie, they've got to get you to disbelieve in the experimental method. Like, the experimental method is just for merely scientific kinds of medicine, not amazing alternative medicine like theirs. Or a good and virtuous person should believe as strongly as they can, no matter what the evidence says. Or truth doesn't exist and there's no such thing as objective reality. A lot of common wisdom like that isn't just mistaken, it's anti-epistemology, it's systematically wrong. Every rule of rationality that tells you how to find the truth, there's someone out there who needs you to believe the opposite. If you once tell a lie, the truth is ever after your enemy; and there's a lot of people out there telling lies.

In a moral dilemma where you lost something either way, making the choice would feel bad either way, so you could temporarily save yourself a little mental pain by refusing to decide. At the cost of not being able to plan anything in advance, and at the cost of incurring a huge bias toward inaction or waiting until too late...

Because the way people are built, Hermione, the way people are built to feel inside -" Harry put a hand over his own heart, in the anatomically correct position, then paused and moved his hand up to point toward his head at around the ear level, "- is that they hurt when they see their friends hurting. Someone inside their circle of concern, a member of their own tribe. That feeling has an off-switch, an off-switch labeled 'enemy' or 'foreigner' or sometimes just 'stranger'. That's how people are, if they don't learn otherwise.

Trying to figure out how something works on that deep level, the first ninety-nine explanations you come up with are wrong. The hundredth is right. So you have to learn how to admit you're wrong, over and over and over again. It doesn't sound like much, but it's so hard that most people can't do science. Always questioning yourself, always taking another look at things you've always taken for granted," like having a Snitch in Quidditch, "and every time you change your mind, you change yourself.

And then Harry Potter had launched in to a speech that was inspiring, yet vague. A speech to the effect that Fred and George and Lee had tremendous potential if they could just learn to be weirder. To make people's live surreal, instead of just surprising them with the equivalents of buckets of water propped above doors. (Fred and George had exchanged interested looks, they'd never thought of that one.) Harry Potter had invoked a picture of the prank they'd pulled on Neville - which, Harry had mentioned with some remorse, the Sorting Hat had chewed him out on - but which must have made Neville doubt his own sanity. For Neville it would have felt like being suddendly transported into an alternate universe. The same way everyone else had felt when they'd seen Snape apologize. That was the true power of pranking.

Aside from helping people with their homework, or anything else they needed, she really didn't know how to meet people. She didn't feel like she was a shy person. She thought of herself as a take-charge sort of girl. And yet, somehow, if there wasn't some request along the lines of "I can't remember how to do long division" then it was just too awkward to go up to someone and say... what? She'd never been able to figure out what. And there didn't seem to be a standard information sheet, which was ridiculous. The whole business of meeting people had never seemed sensible to her. Why did she have to take all the responsibility herself when there were two people involved? Why didn't adults ever help? She wished some other girl would just walk up to her and say, "Hermione, the teacher told me to be friends with you".

The glass display cases had shown rock-throwers crafted by the Australian aborigines - like giant wooden shoehorns, they'd looked, but smoothed and carved and ornamented with the most painstaking care. In the 40,000 years since anatomically modern humans had migrated to Australia from Asia, nobody had invented the bow-and-arrow. It really made you appreciate how non-obvious was the idea of Progress. Why would you even think of Invention as something important, if all your history's heroic tales were of great warriors and defenders instead of Thomas Edison? How could anyone possibly have suspected, while carving a rock-thrower with painstaking care, that someday human beings would invent rocket ships and nuclear energy?

You can only arrive at mastery by practicing the techniques you have learned, facing challenges and apprehending them, using to the fullest the tools you have been taught, until they shatter in your hands and you are left in the midst of wreckage absolute... I cannot create masters. I have never known how to create masters. Go, then, and fail... You have been shaped into something that may emerge from the wreckage, determined to remake your Art. I cannot create masters, but if you had not been taught, your chances would be less. The higher road begins after the Art seems to fail you; though the reality will be that it was you who failed your Art.

One reader of an early draft of this chapter complained at this point, saying that by treating the hypothesis of God as just one more scientific hypothesis, to be evaluated by the standards of science in particular and rational thought in general, Dawkins and I are ignoring the very widespread claim by believers in God that their faith is quite beyond reason, not a matter to which such mundane methods of testing applies. It is not just unsympathetic, he claimed, but strictly unwarranted for me simply to assume that the scientific method continues to apply with full force in this domain of truth. Very well, let's consider the objection. I doubt that the defender of religion will find it attractive, once we explore it carefully. The philosopher Ronaldo de Souza once memorably described philosophical theology as "intellectual tennis without a net," and I readily allow that I have indeed been assuming without comment or question up to now that the net of rational judgement was up. But we can lower it if you really want to. It's your serve. Whatever you serve, suppose I return service rudely as follows: "What you say implies that God is a ham sandwich wrapped in tin foil. That's not much of a God to worship!". If you then volley back, demanding to know how I can logically justify my claim that your serve has such a preposterous implication, I will reply: "oh, do you want the net up for my returns, but not for your serves? Either way the net stays up, or it stays down. If the net is down there are no rules and anybody can say anything, a mug's game if there ever was one. I have been giving you the benefit of the assumption that you would not waste your own time or mine by playing with the net down.

It [Communism] is not new. It is, in fact, man's second oldest faith. Its promise was whispered in the first days of the Creation under the Tree of the Knowledge of Good and Evil: "Ye shall be as gods." It is the great alternative faith of mankind. Like all great faiths, its force derives from a simple vision. Other ages have had great visions. They have always been different versions of the same vision: the vision of God and man's relationship to God. The Communist vision is the vision of Man without God. It is the vision of man's mind displacing God as the creative intelligence of the world. It is the vision of man's liberated mind, by the sole force of its rational intelligence, redirecting man's destiny and reorganizing man's life and the world. It is the vision of man, once more the central figure of the Creation, not because God made man in his image, but because man's mind makes him the most intelligent of the animals. Copernicus and his successors displaced man as the central fact of the universe by proving that the earth was not the central star of the universe. Communism restores man to his sovereignty by the simple method of denying God.

We are indeed dealing with two entirely different approaches to reality and to solving problems — methods we will here call the rational method and the magical one. The rational approach works quite well in certain situations, such as mass production of goods, or in certain kinds of scientific measurements — but all in all the rational method, as it is understood and used, does not work as an overall approach to life, or in the solving of problems that involve subjective rather than objective measurements or calculations. The magical approach has far greater weight, if you use it and allow yourselves to operate in that fashion, for it has the weight of your basic natural orientation.

Harry had read once, somewhere, that the opposite of happiness wasn't sadness, but boredom; and the author had gone on to say that to find happiness in life you asked yourself not what would make you happy, but what would excite you. And by the same reasoning, hatred wasn't the true opposite of love. Even hatred was a kind of respect that you could give to someone's existence. If you cared about someone enough to prefer their dying to their living, it meant you were thinking about them.

reality usually delivers results a little worse than the 'worst-case scenario'. It's called the planning fallacy, and the best way to fix it is to ask how long things took the last time you tried them. That's called using the outside view instead of the inside view. But when you're doing something new and can't do that, you just have to be really, really, really pessimistic. Like, so pessimistic that reality actually comes out better than you expected around as often and as much as it comes out worse. It's actually really hard to be so pessimistic that you stand a decent chance of undershooting real life.

No intelligent radical can fail to realize the need of the rational education of the young. The rearing of the child must become a process of liberation by methods which shall not impose ready-made ideas, but which should aid the child's natural self-unfoldment. The purpose of such an education is not to force the child's adaptation to accepted concepts. but to give free play to his [and her] originality, initiative, and individuality. Only by freeing education from compulsion and restraint can we create the environment for the manifestation of the spontaneous interest and inner incentives on the part of the child. Only thus can we supply rational conditions favorable to the development of the child's natural tendencies and his latent emotional and mental faculties. Such methods of education, essentially aiding the child's imitative quality and ardor for knowledge, will develop a generation of healthy intellectual independence. It will produce men and women capable, in the words of Francisco Ferrer, “of evolving without stopping, of destroying and renewing their environment without cessation; of renewing themselves also; always ready to accept what is best, happy in the triumph of new ideas, aspiring to live multiple lives in one life.

am touched that you are trying to comprehend me. A friend could not be more loving. I am more touched, still, that you are trying to understand—through rational thought—that which cannot be understood at all. There is no exact principle to be found here. The divine, as Boehme said, is unground—unfathomable, something outside the world as we experience it. But this is a difference of our minds, dearest one. I wish to arrive at revelation on wings, while you advance steadily on foot, magnifying glass in hand. I am a smattering wanderer, seeking God within the outer contours, searching for a new way of knowing. You stand upon the ground, and consider the evidence inch by inch. Your way is more rational and more methodical, but I cannot change my way.” “I do have a dreadful love for understanding,” Alma admitted. “Indeed you do love it, though it is not dreadful,

The Headmaster told Professor Flitwick that this was, indeed, a secret and delicate matter of which he had already been informed, and that he did not think pressing it at this time would help me or anyone. Professor Flitwick started to say something about the Headmaster's usual plotting going much too far, and I had to interrupt at that point and explain that it had been my own idea and not anything the Headmaster forced me into, so Professor Flitwick spun around and started lecturing me, and the Headmaster interrupted him and said that as the Boy-Who-Lived I was doomed to have weird and dangerous adventures so I was safer if I got into them on purpose instead of waiting for them to happen by accident, and that was when Professor Flitwick threw up his little hands and started shrieking in a high-pitched voice at both of us about how he didn't care what we were cooking up together, but this wasn't ever to happen again for as long as I was in Ravenclaw House or he would have me thrown out and I could go to Gryffindor which was where all this Dumbledoring belonged -

I have a feeling," Harry said finally, "that we're coming at this from the wrong angle. There's a tale I once heard about some students who came into a physics class, and the teacher showed them a large metal plate near a fire. She ordered them to feel the metal plate, and they felt that the metal nearer the fire was cooler, and the metal further away was warmer. And she said, write down your guess for why this happens. So some students wrote down 'because of how the metal conducts heat', and some students wrote down 'because of how the air moves', and no one said 'this just seems impossible', and the real answer was that before the students came into the room, the teacher turned the plate around." "Interesting," said Professor Quirrell. "That does sound similar. Is there a moral?" "That your strength as a rationalist is your ability to be more confused by fiction than by reality," said Harry. "If you're equally good at explaining any outcome, you have zero knowledge. The students thought they could use words like 'because of heat conduction' to explain anything, even a metal plate being cooler on the side nearer the fire. So they didn't notice how confused they were, and that meant they couldn't be more confused by falsehood than by truth. If you tell me that the centaurs were under the Imperius Curse, I still have the feeling of something being not quite right. I notice that I'm still confused even after hearing your explanation.

Each religion makes scores of purportedly factual assertions about everything from the creation of the universe to the afterlife. But on what grounds can believers presume to know that these assertions are true? The reasons they give are various, but the ultimate justification for most religious people’s beliefs is a simple one: we believe what we believe because our holy scriptures say so. But how, then, do we know that our holy scriptures are factually accurate? Because the scriptures themselves say so. Theologians specialize in weaving elaborate webs of verbiage to avoid saying anything quite so bluntly, but this gem of circular reasoning really is the epistemological bottom line on which all 'faith' is grounded. In the words of Pope John Paul II: 'By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals.' It goes without saying that this begs the question of whether the texts at issue really were authored or inspired by God, and on what grounds one knows this. 'Faith' is not in fact a rejection of reason, but simply a lazy acceptance of bad reasons. 'Faith' is the pseudo-justification that some people trot out when they want to make claims without the necessary evidence. But of course we never apply these lax standards of evidence to the claims made in the other fellow’s holy scriptures: when it comes to religions other than one’s own, religious people are as rational as everyone else. Only our own religion, whatever it may be, seems to merit some special dispensation from the general standards of evidence. And here, it seems to me, is the crux of the conflict between religion and science. Not the religious rejection of specific scientific theories (be it heliocentrism in the 17th century or evolutionary biology today); over time most religions do find some way to make peace with well-established science. Rather, the scientific worldview and the religious worldview come into conflict over a far more fundamental question: namely, what constitutes evidence. Science relies on publicly reproducible sense experience (that is, experiments and observations) combined with rational reflection on those empirical observations. Religious people acknowledge the validity of that method, but then claim to be in the possession of additional methods for obtaining reliable knowledge of factual matters — methods that go beyond the mere assessment of empirical evidence — such as intuition, revelation, or the reliance on sacred texts. But the trouble is this: What good reason do we have to believe that such methods work, in the sense of steering us systematically (even if not invariably) towards true beliefs rather than towards false ones? At least in the domains where we have been able to test these methods — astronomy, geology and history, for instance — they have not proven terribly reliable. Why should we expect them to work any better when we apply them to problems that are even more difficult, such as the fundamental nature of the universe? Last but not least, these non-empirical methods suffer from an insuperable logical problem: What should we do when different people’s intuitions or revelations conflict? How can we know which of the many purportedly sacred texts — whose assertions frequently contradict one another — are in fact sacred?

At first he found it amusing. He coined a law intended to have the humor of a Parkinson’s law that "The number of rational hypotheses that can explain any given phenomenon is infinite." It pleased him never to run out of hypotheses. Even when his experimental work seemed dead-end in every conceivable way, he knew that if he just sat down and muddled about it long enough, sure enough, another hypothesis would come along. And it always did. It was only months after he had coined the law that he began to have some doubts about the humor or benefits of it. If true, that law is not a minor flaw in scientific reasoning. The law is completely nihilistic. It is a catastrophic logical disproof of the general validity of all scientific method! If the purpose of scientific method is to select from among a multitude of hypotheses, and if the number of hypotheses grows faster than experimental method can handle, then it is clear that all hypotheses can never be tested. If all hypotheses cannot be tested, then the results of any experiment are inconclusive and the entire scientific method falls short of its goal of establishing proven knowledge

The world shown us in books, whether the books be confessed epics or professed gospels, or in codes, or in political orations, or in philosophic systems, is not the main world at all: it is only the self-consciousness of certain abnormal people who have the specific artistic talent and temperament. A serious matter this for you and me, because the man whose consciousness does not correspond to that of the majority is a madman; and the old habit of worshipping madmen is giving way to the new habit of locking them up. And since what we call education and culture is for the most part nothing but the substitution of reading for experience, of literature for life, of the absolete fictitious for the contemporary real, education, as you no doubt observed at Oxford, destroys, by supplantation, every mind that is not strong enough to see through the imposture and to use the great Masters of Arts as what they really are and no more: that is, patentees of highly questionable methods of thinking, and manufacturers of highly questionable, and for the majority but half valid representations of life. The school boy who uses his Homer to throw at his fellow's head makes perhaps the safest and most rational use of him; and I observe with reassurance that you occasionally do the same, in your prime, with your Aristotle.

Ending up with that gigantic outsized brain must have taken some sort of runaway evolutionary process, something that would push and push without limits. And today's scientists had a pretty good guess at what that runaway evolutionary process had been. Harry had once read a famous book called Chimpanzee Politics. The book had described how an adult chimpanzee named Luit had confronted the aging alpha, Yeroen, with the help of a young, recently matured chimpanzee named Nikkie. Nikkie had not intervened directly in the fights between Luit and Yeroen, but had prevented Yeroen's other supporters in the tribe from coming to his aid, distracting them whenever a confrontation developed between Luit and Yeroen. And in time Luit had won, and become the new alpha, with Nikkie as the second most powerful... ...though it hadn't taken very long after that for Nikkie to form an alliance with the defeated Yeroen, overthrow Luit, and become the new new alpha. It really made you appreciate what millions of years of hominids trying to outwit each other - an evolutionary arms race without limit - had led to in the way of increased mental capacity. 'Cause, y'know, a human would have totally seen that one coming.

Thus, by science I mean, first of all, a worldview giving primacy to reason and observation and a methodology aimed at acquiring accurate knowledge of the natural and social world. This methodology is characterized, above all else, by the critical spirit: namely, the commitment to the incessant testing of assertions through observations and/or experiments — the more stringent the tests, the better — and to revising or discarding those theories that fail the test. One corollary of the critical spirit is fallibilism: namely, the understanding that all our empirical knowledge is tentative, incomplete and open to revision in the light of new evidence or cogent new arguments (though, of course, the most well-established aspects of scientific knowledge are unlikely to be discarded entirely). . . . I stress that my use of the term 'science' is not limited to the natural sciences, but includes investigations aimed at acquiring accurate knowledge of factual matters relating to any aspect of the world by using rational empirical methods analogous to those employed in the natural sciences. (Please note the limitation to questions of fact. I intentionally exclude from my purview questions of ethics, aesthetics, ultimate purpose, and so forth.) Thus, 'science' (as I use the term) is routinely practiced not only by physicists, chemists and biologists, but also by historians, detectives, plumbers and indeed all human beings in (some aspects of) our daily lives. (Of course, the fact that we all practice science from time to time does not mean that we all practice it equally well, or that we practice it equally well in all areas of our lives.)

Every time I glanced at Ren, I saw that he was watching me. When we finally reached the end of the tunnel and saw the stone steps that led to the surface, Ren stopped. “Kelsey, I have one final request of you before we head up.” “And what would that be? Want to talk about tiger senses or monkey bites in strange places maybe?” “No. I want you to kiss me.” I sputtered, “What? Kiss you? What for? Don’t you think you got to kiss me enough on this trip?” “Humor me, Kells. This is the end of the line for me. We’re leaving the place where I get to be a man all the time, and I have only my tiger’s life to look forward to. So, yes, I want you to kiss me one more time.” I hesitated. “Well, if this works, you can go around kissing all the girls you want to. So why bother with me right now?” He ran a hand through his hair in frustration. “Because! I don’t want to run around kissing all the other girls! I want to kiss you!” “Fine! If it will shut you up!” I leaned over and pecked him on the cheek. “There!” “No. Not good enough. On the lips, my prema.” I leaned over and pecked him on the lips. “There. Can we go now?” I marched up the first two steps, and he slipped his hand under my elbow and spun me around, twisting me so that I fell forward into his arms. He caught me tightly around the waist. His smirk suddenly turned into a sober expression. “A kiss. A real one. One that I’ll remember.” I was about to say something brilliantly sarcastic, probably about him not having permission, when he captured my mouth with his. I was determined to remain stiff and unaffected, but he was extremely patient. He nibbled on the corners of my mouth and pressed soft, slow kisses against my unyielding lips. It was so hard not to respond to him. I made a valiant struggle, but sometimes the body betrays the mind. He slowly, methodically swept aside my resistance. And, feeling he was winning, he pressed ahead and began seducing me even more skillfully. He held me tightly against his body and ran a hand up to my neck where he began to massage it gently, teasing my flesh with his fingertips. I felt the little love plant inside me stretch, swell, and unfurl its leaves, like he was pouring Love Potion # 9 over the thing. I gave up at that point and decided what the heck. I could always use a rototiller on it. And I rationalized that when he breaks my heart, at least I will have been thoroughly kissed. If nothing else, I’ll have a really good memory to look back on in my multi-cat spinsterhood. Or multi-dog. I think I will have had my fill of cats. I groaned softly. Yep. Dogs for sure.

This story takes place a half a billion years ago-an inconceivably long time ago, when this planet would be all but recognizable to you. Nothing at all stirred on the land except the wind and the dust. Not a single blade of grass waved in the wind, not a single cricket chirped, not a single bird soared in the sky. All these things were tens of millions of years away in the future. But of course there was an anthropologist on hand. What sort of world would it be without an anthropologist? He was, however a very depressed and disillusioned anthropologist, for he'd been everywhere on the planet looking for someone to interview, and every tape in his knapsack was as blank as the sky. But one day as he was moping alongside the ocean he saw what seemed to be a living creature in the shallows off shore. It was nothing to brag about, just sort of a squishy blob, but it was the only prospect he'd seen in all his journeys, so he waded out to where it was bobbing in the waves. He greeted the creature politely and was greeted in kind, and soon the two of them were good friends. The anthropologist explained as well as he could that he was a student of life-styles and customs, and begged his new friend for information of this sort, which was readily forthcoming. ‘And now’, he said at last, ‘I'd like to get on tape in your own words some of the stories you tell among yourselves.’ ‘Stories?’ the other asked. ‘You know, like your creation myth, if you have one.’ ‘What is a creation myth?’ the creature asked. ‘Oh, you know,’ the anthropologist replied, ‘the fanciful tale you tell your children about the origins of the world.’ Well, at this, the creature drew itself up indignantly- at least as well as a squishy blob can do- and replied that his people had no such fanciful tale. ‘You have no account of creation then?’ ‘Certainly we have an account of creation,’ the other snapped. ‘But its definitely not a myth.’ ‘Oh certainly not,’ the anthropologist said, remembering his training at last. ‘Ill be terribly grateful if you share it with me.’ ‘Very well,’ the creature said. ‘But I want you to understand that, like you, we are a strictly rational people, who accept nothing that is not based on observation, logic, and scientific method.’ ‘"Of course, of course,’ the anthropologist agreed. So at last the creature began its story. ‘The universe,’ it said, ‘was born a long, long time ago, perhaps ten or fifteen billion years ago. Our own solar system-this star, this planet, and all the others- seem to have come into being some two or three billion years ago. For a long time, nothing whatever lived here. But then, after a billion years or so, life appeared.’ ‘Excuse me,’ the anthropologist said. ‘You say that life appeared. Where did that happen, according to your myth- I mean, according to your scientific account.’ The creature seemed baffled by the question and turned a pale lavender. ‘Do you mean in what precise spot?’ ‘No. I mean, did this happen on land or in the sea?’ ‘Land?’ the other asked. ‘What is land?’ ‘Oh, you know,’ he said, waving toward the shore, ‘the expanse of dirt and rocks that begins over there.’ The creature turned a deeper shade of lavender and said, ‘I cant imagine what you're gibbering about. The dirt and rocks over there are simply the lip of the vast bowl that holds the sea.’ ‘Oh yes,’ the anthropologist said, ‘I see what you mean. Quite. Go on.’ ‘Very well,’ the other said. ‘For many millions of centuries the life of the world was merely microorganisms floating helplessly in a chemical broth. But little by little, more complex forms appeared: single-celled creatures, slimes, algae, polyps, and so on.’ ‘But finally,’ the creature said, turning quite pink with pride as he came to the climax of his story, ‘but finally jellyfish appeared!

The consequences of this amassing of fortunes were first felt in the catastrophe experienced by small farmers in Europe and England. The peasants became impoverished, dependent workers crowded into city slums. For the first time in human history, the majority of Europeans depended for their livelihood on a small wealthy minority, a phenomenon that capitalist-based colonialism would spread worldwide. The symbol of this new development, indeed its currency, was gold. Gold fever drove colonizing ventures, organized at first in pursuit of the metal in its raw form. Later the pursuit of gold became more sophisticated, with planters and merchants establishing whatever conditions were necessary to hoard as much gold as possible. Thus was born an ideology: the belief in the inherent value of gold despite its relative uselessness in reality. Investors, monarchies, and parliamentarians devised methods to control the processes of wealth accumulation and the power that came with it, but the ideology behind gold fever mobilized settlers to cross the Atlantic to an unknown fate. Subjugating entire societies and civilizations, enslaving whole countries, and slaughtering people village by village did not seem too high a price to pay, nor did it appear inhumane. The systems of colonization were modern and rational, but its ideological basis was madness.

Pham Nuwen spent years learning to program/explore. Programming went back to the beginning of time. It was a little like the midden out back of his father’s castle. Where the creek had worn that away, ten meters down, there were the crumpled hulks of machines—flying machines, the peasants said—from the great days of Canberra’s original colonial era. But the castle midden was clean and fresh compared to what lay within the Reprise’s local net. There were programs here that had been written five thousand years ago, before Humankind ever left Earth. The wonder of it—the horror of it, Sura said—was that unlike the useless wrecks of Canberra’s past, these programs still worked! And via a million million circuitous threads of inheritance, many of the oldest programs still ran in the bowels of the Qeng Ho system. Take the Traders’ method of timekeeping. The frame corrections were incredibly complex—and down at the very bottom of it was a little program that ran a counter. Second by second, the Qeng Ho counted from the instant that a human had first set foot on Old Earth’s moon. But if you looked at it still more closely. . .the starting instant was actually some hundred million seconds later, the 0-second of one of Humankind’s first computer operating systems. So behind all the top-level interfaces was layer under layer of support. Some of that software had been designed for wildly different situations. Every so often, the inconsistencies caused fatal accidents. Despite the romance of spaceflight, the most common accidents were simply caused by ancient, misused programs finally getting their revenge. “We should rewrite it all,” said Pham. “It’s been done,” said Sura, not looking up. She was preparing to go off-Watch, and had spent the last four days trying to root a problem out of the coldsleep automation. “It’s been tried,” corrected Bret, just back from the freezers. “But even the top levels of fleet system code are enormous. You and a thousand of your friends would have to work for a century or so to reproduce it.” Trinli grinned evilly. “And guess what—even if you did, by the time you finished, you’d have your own set of inconsistencies. And you still wouldn’t be consistent with all the applications that might be needed now and then.” Sura gave up on her debugging for the moment. “The word for all this is ‘mature programming environment.’ Basically, when hardware performance has been pushed to its final limit, and programmers have had several centuries to code, you reach a point where there is far more signicant code than can be rationalized. The best you can do is understand the overall layering, and know how to search for the oddball tool that may come in handy—take the situation I have here.” She waved at the dependency chart she had been working on. “We are low on working fluid for the coffins. Like a million other things, there was none for sale on dear old Canberra. Well, the obvious thing is to move the coffins near the aft hull, and cool by direct radiation. We don’t have the proper equipment to support this—so lately, I’ve been doing my share of archeology. It seems that five hundred years ago, a similar thing happened after an in-system war at Torma. They hacked together a temperature maintenance package that is precisely what we need.” “Almost precisely.
