They were scientists enough to admit that they were wrong.

Ambitious men will not wait and unscrupulous men will not hang back. By their every action they will hasten the decay of the worlds.

Even as a youngster, though, I could not bring myself to believe that if knowledge presented danger, the solution was ignorance. To me, it always seemed that the solution had to be wisdom. You did not refuse to look at danger, rather you learned how to handle it safely.

He didn’t believe that, surely.” “Of course not! But he had to pretend he did, as otherwise he would have had no choice but to be insulted. And since there would be nothing he could do about that, being insulted would only lead to humiliation. And since he didn’t want that, the simplest path to follow was to believe what I said.

What do you require to exchange your ideas for mine?” “You think my convictions are for sale?” “Why not?” came the cold response. “Isn’t that your business, buying and selling?” “Only at a profit,” said Mallow,

Carbon is the basis of human life and iron of robot life. It becomes easy to speak of C/Fe when you wish express a culture that combines the best of the two on an equal but parallel basis.

Sizzling Saturn, we’ve got a lunatic robot on our hands.

Human beings sometimes find a kind of pleasure in nursing painful emotions, in blaming themselves without reason or even against reason.

The fall of Empire, gentlemen, is a massive thing, however, and not easily fought. It is dictated by a rising bureaucracy, a receding initiative, a freezing of caste, a damming of curiosity — a hundred other factors. It has been going on, as I have said, for centuries, and it is too majestic and massive a movement to stop.

What do you see happening to the idea of dignity to human species if this population growth continues at its present rate?

It's going to destroy it all. I use what I call my bathroom metaphor. If two people live in an apartment, and there are two bathrooms, then both have what I call freedom of the bathroom, go to the bathroom any time you want, and stay as long as you want to for whatever you need. And this to my way is ideal. And everyone believes in the freedom of the bathroom. It should be right there in the Constitution. But if you have 20 people in the apartment and two bathrooms, no matter how much every person believes in freedom of the bathroom, there is no such thing. You have to set up, you have to set up times for each person, you have to bang at the door, aren't you through yet, and so on. And in the same way, democracy cannot survive overpopulation. Human dignity cannot survive it. Convenience and decency cannot survive it. As you put more and more people onto the world, the value of life not only declines, but it disappears. It doesn't matter if someone dies.
