On some pitch black mornings, hearing what I knew was a cold wind howling outside, I might think, "Well, it is certainly comfortable in this bed, and maybe it wouldn't hurt if I just skipped practicing to-day." But my response to this was not to draw on something called will power, to insult or threaten myself, but to take a longer look at my life, to extend my vision, to think about the whole of my experience, to reconnect present and future, and quite specifically, to ask myself, "Do you like playing the cello or not? Would you like to play it better or not?" When I put the matter this way I could see that I enjoyed playing the cello more than I enjoyed staying in bed. So I got up. If, as sometimes happened or happens, I do stay in bed, not sleeping, not really thinking, but just not getting up, it is not because will power is weak but because I have temporarily become disconnected, so to speak, from the wholeness of my life. I am living in that Now that some people pursue so frantically, that gets harder to find the harder we look for it.

When I was young, I thought the act of getting older meant, year by year, getting more sophisticated, more hard, cool, and unpitying. Less innocent.
Maybe that was a childish idea of what getting older was about. Maybe adults, mature adults, get more innocent with time, not less. Because the word "innocent" does not mean "naive," it means "not guilty."
Children do small evils to each other, schoolyard fights and insults, not because their hearts are pure, but because their powers are small. Grown-ups have more power. Some of them do great evils with that power. But what about the ones who don't? Aren't they more innocent than children, not less?

Numerical arithmetic should look to children like a simpler and faster way of doing things that they know how to do already, not a set of mysterious recipes for getting right answers to meaningless questions.

“Do as I say, not as I do:” this is considered the very motto of hypocrisy. But does anyone believe that having a good character is as easy as wanting it? If virtue is as difficult as other excellences, there must be few or none who are perfectly virtuous. If the rest of us are not even to talk about virtue or express admiration for it, how shall anyone improve? A hypocrite is one who claims virtue beyond what he possesses, not one who recommends virtue beyond what he claims. If a man’s principles are no better than his character, it is less likely to be a sign of an exemplary character than a sign of debased principles.

"I'm writing a book on magic," I explain, and I'm asked, "Real magic?" By real magic people mean miracles, thaumaturgical acts, and supernatural powers. "No," I answer. "Conjuring tricks, not real magic."
Real magic, in other words, refers to the magic that is not real, while the magic that is real, that can actually be done, is not real magic.

I don't know how many people I've met who hold beliefs like "in three card stud a four is more likely to come up after an eight than a six." What the fuck? Is the concept of random that hard to grasp?
It's pretty depressing. Not too long ago, someone I know expressed the belief that red is more likely to come up on a roulette table if the last five spins landed on black. He holds a graduate degree in computer science.
There is a mathematical style in which proofs are presented as strings of unmotivated tricks that miraculously do the job, but we found greater intellectual satisfaction in showing how each next step in the argument, if not actually forced, is at least something sweetly reasonable to try. Another reason for avoiding [pulling] rabbits [out of the magicians's hat] as much as possible was that we did not want to teach proofs, we wanted to teach proof design. Eventually, expelling rabbits became another joy of my professional life.

...you have to make a conscious effort to keep your ideas about what you want from being contaminated by what seems possible.This is isomorphic to the principle that you should prevent your beliefs about how things are from being contaminated by how you wish they were. Most people let them mix pretty promiscuously. The continuing popularity of religion is the most visible index of that.

Defects of empirical knowledge have less to do with the ways we go wrong in philosophy than defects of character do: such things as the simple inability to shut up; determination to be thought deep; hunger for power; fear, especially the fear of an indifferent universe.

We all know many things about the world. What form or shape does our knowledge take? We may be able to say some of what we know, though in many people there is a deep and dangerous confusion between what they say and think they believe and what they really believe. But all of us know much more than we can say, and many times we cannot really put it into words at all.
For example, if we have eaten them, we know what strawberries taste like. We have in us somewhere knowledge---a memory, many memories---of the taste of strawberries. Not just one berry either, but many, more or less ripe, or sweet, or tasty. But how can we really speak of the taste of a strawberry? When we bite into a berry, we are ready to taste a certain kind of taste; if we taste something very different, we are surprised. It is this---what we expect or what surprises us---that tells us best what we really know.
We know many other things that we cannot say. We know what a friend looks like, so well that we may say, seeing him after some time, that he looks older or no older; heavier or thinner; worried or at peace, or happy. But our answers are usually so general that we could not give a description from which someone who had never seen our friend could recognize him.

But I distrusted the whole game. Intuitively, I wonder about the honesty and proficiency of writers who opine on everything from Iran to education to drug policy to health care to cap and trade to race. Perhaps these people simply have more brains than me, but the catch-all nature of punditry, the need to speak on every policy topic as though one were an expert, is exactly what I hope to avoid.
[N]ot just our actions and reactions but our very perceptions, what we think we see, feel, smell, and so on, are deeply affected by our mental model, our assumptions and beliefs about the way things really are. In a great variety of experiments with perception, many people, many times over, have shown this to be true. Therefore it is not just fancy and tricky talk to say that each of us lives, not so much in an objective out-there world that is the same for all of us, but in his mental model of that world. It is this model of the world that he experiences. We are not, then starting an impossible contradiction, or using language carelessly, when we say that I live in my mental model of the world, and my mental model lives in me.

...According to an old story, a lord of ancient China once asked his physician, a member of a family of healers, which of them was the most skilled in the art.
The physician, whose reputation was such that his name became synonymous with medical science in China, replied, "My eldest brother sees the spirit of sickness and removes it before it takes shape and so his name does not get out of the house."
"My elder brother cures sickness when it is still extremely minute, so his name does not get out of the neighborhood."

"I’m moved to laughter at the thought of how presumptuous it would be to reject mathematics for philosophical reasons. How would you like the job of telling the mathematicians that they must change their ways…now that philosophy has discovered that there are no classes? Can you tell them, with a straight face, to follow philosophical argument wherever it leads? If they challenge your credentials, will you boast of philosophy’s other great discoveries: that motion is impossible, that a Being than which no greater can be conceived cannot be conceived no...
The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work.

I would note that orthodox statistics and the Copenhagen interpretation of quantum theory are just two different manifestations of a single intellectual disease, closely related to logical positivism, which has debilitated every area of theoretical science in this century. The symptoms of this disease are the loss of conceptual discrimination; i.e., the inability to distinguish between probability and frequency, between reality and our knowledge of reality, between meaning and method of testing, etc.

At the other end of the spectrum are the opponents of reductionism who are appalled by what they feel to be the bleakness of modern science. To whatever extent they and their world can be reduced to a matter of particles or fields and their interactions, they feel diminished by that knowledge....I would not try to answer these critics with a pep talk about the beauties of modern science. The reductionist worldview is chilling and impersonal. It has to be accepted as it is, not because we like it, but because that is the way the world works.

I thought about med school again, the anatomy class I had told Jason about. Candice Boone, my one-time almost-fiancée, had shared that class with me. She had been stoic during the dissection but not afterward. A human body, she said, ought to contain love, hate, courage, cowardice, soul, spirit ... not this slimy assortment of blue and red imponderables. Yes. And we ought not to be dragged unwilling into a harsh and deadly future.
But the world is what it is and won't be bargained with. I said as much to Candice.
She told me I was "cold". But it was still the closest thing to wisdom I had ever been able to muster.

"The reader in search of knock-down arguments in favor of my theories will go away disappointed. Whether or not it would be nice to knock disagreeing philosophers down by sheer force of argument, it cannot be done. Philosophical theories are never refuted conclusively. (or hardly ever. Gödel and Gettier may have done it.) The theory survives its refutation - at a price. Perhaps that is something we can settle more or less conclusively. But when all is said and done, and all the tricky arguments and distinctions and counterexamples have been discovered...

Some people are always critical of vague statements. I tend rather to be critical of precise statements; they are the only ones which can correctly be labeled 'wrong'.

Surely, to label a statement "vague" is a higher order of insult than to call it "wrong". Newton was wrong but at least he was not vague.

Many of the arguments on LW remind me of this quote:
"for the obscurity of the distinctions and of the principles that they use is the reason why they talk about everything as confidently as if they knew about it, and defend everything they say about it against the most subtle and knowledgeable, without leaving any room to convince them of their mistake. In doing this they seem to me to resemble a blind person who, in order to fight without any disadvantage against a sighted person, would bring them into the depths of a very dark celar."

One request I must make of my reader, which is, that in judging these poems he would decide by his own feelings genuinely, and not by reflection upon what will probably be the judgment of others. How common is it to hear a person say, I myself do not object to this style of composition, or this or that expression, but to such and such classes of people it will appear mean or ludicrous! This mode of criticism, so destructive of all sound unadulterated judgment, is almost universal: let the reader then abide, independently, by his own feelings, and, if he ...

Leadership skills are quite different from management skills. When you "manage," by definition, you're trying to distribute resources where they will do the company the most good. When you "lead," by definition, you're trying to get those resources distributed to yourself. Obviously, leadership is a better way to go. It's easier too.

..."As a final practical maxim, relative to these habits of the will, we may, then, offer something like this: Keep the faculty of effort alive in you by a little gratuitous exercise every day. That is, be systematically ascetic or heroic in little unnecessary points, do every day or 2 something for no other reason than that you would rather not do it, so that when the hour of dire need draws nigh, it may find you not unnerved and untrained to stand the test. Asceticism of this sort is like the insurance which a man pays on his house and goods. The tax

All rested, eventually. Their technology climbed to some complacent asymptote, and stopped—and so they do not stand before you now. Now even my creators grow fat and slow. Their environment mastered, their enemies broken, they can afford more pacifist luxuries. Their machines softened the universe for them, their own contentment robs them of incentive. They forget that hostility and technology climb the cultural ladder together, they forget that it's not enough to be smart. You also have to be mean.

In all sensation we pick and choose, interpret, seek and impose order, and devise and test hypotheses about what we witness.

Dammit, I've read Distress and I know without looking exactly the context of the Egan quote. I was practically cheering for Rourke in that chapter. But there's a big gap between encountering an idea and finding it good, and actually applying it after closing the book.
You say that your opponent lacks humanity. It's the oldest semantic weapon there is. Think of all the categories of people who've been classified as non-human, in various cultures, at various times. People from other tribes. People with other skin colors. Slaves. Women. The mentally ill. The deaf. Homosexuals. Jews. Bosnians, Croats, Serbs, Armenians, Kurds [...]
But suppose you accuse me of 'lacking humanity.' What does that actually mean? What am I likely to have done? Murdered someone in cold blood? Drowned a puppy? Eaten meat? Failed to be moved by Beethoven's Fifth? Or just failed to have—or to seek—an emotional life identical to your own in every respect? Failed to share all your values and aspirations?
The answers is: 'any one of the above.' Which is why it's so fucking lazy. Questioning someone's 'humanity' puts them in the company of serial killers—which saves you the trouble of having to claim anything intelligent about their views.
