Prediction in a complex world is a chancy business. Every decision that a survival machine takes is a gamble, and it is the business of genes to program brains in advance so that on average they take decisions that pay off. The currency used in the casino of evolution is survival, strictly gene survival, but for many purposes individual survival is a reasonable approximation. ↗
His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic? We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth. … But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter. His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of confused observations made through the centuries were all interconnected. ↗
But today our very survival depends on our ability to stay awake, to adjust to new ideas, to remain vigilant and to face the challenge of change. The large house in which we live demands that we transform this world-wide neighborhood into a world – wide brotherhood. Together we must learn to live as brothers or together we will be forced to perish as fools. We must work passionately and indefatigably to bridge the gulf between our scientific progress and our moral progress. One of the great problems of mankind is that we suffer from a poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually. ↗

I would teach how science works as much as I would teach what science knows. I would assert (given that essentially, everyone will learn to read) that science literacy is the most important kind of literacy they can take into the 21st century. I would undervalue grades based on knowing things and find ways to reward curiosity. In the end, it's the people who are curious who change the world. ↗
I would like [my readers] to better understand human beings and human life as a result of having read [my] stories. I'd like them to feel that this was an experience that made things better for them and an experience that gave them hope. I think that the kind of things that we talk about at this conference -- fantasy very much so, science fiction, and even horror -- the message that we're sending is the reverse of the message sent by what is called "realistic fiction." (I happen to think that realistic fiction is not, in fact, realistic, but that's a side issue.) And what we are saying is that it doesn't have to be like this: things can be different. Our society can be changed. Maybe it's worse, maybe it's better. Maybe it's a higher civilization, maybe it's a barbaric civilization. But it doesn't have to be the way it is now. Things can change. And we're also saying things can change for you in your life. Look at the difference between Severian the apprentice and Severian the Autarch [in The Book of the New Sun], for example. The difference beteween Silk as an augur and Silk as calde [in The Book of the Long Sun]. You see? We don't always have to be this. There can be something else. We can stop doing the thing that we're doing. Moms Mabley had a great line in some movie or other -- she said, "You keep on doing what you been doing and you're gonna keep on gettin' what you been gettin'." And we don't have to keep on doing what we've been doing. We can do something else if we don't like what we're gettin'. I think a lot of the purpose of fiction ought to be to tell people that. ↗
I have been accused of a habit of changing my opinions. I am not myself in any degree ashamed of having changed my opinions. What physicist who was already active in 1900 would dream of boasting that his opinions had not changed during the last half century? In science men change their opinions when new knowledge becomes available; but philosophy in the minds of many is assimilated rather to theology than to science. The kind of philosophy that I value and have endeavoured to pursue is scientific, in the sense that there is some definite knowledge to be obtained and that new discoveries can make the admission of former error inevitable to any candid mind. For what I have said, whether early or late, I do not claim the kind of truth which theologians claim for their creeds. I claim only, at best, that the opinion expressed was a sensible one to hold at the time when it was expressed. I should be much surprised if subsequent research did not show that it needed to be modified. I hope, therefore, that whoever uses this dictionary will not suppose the remarks which it quotes to be intended as pontifical pronouncements, but only as the best I could do at the time towards the promotion of clear and accurate thinking. Clarity, above all, has been my aim. ↗
