Surely, if we take on thinking partners - or, at the least, thinking servants - in the form of machines, we will be more comfortable with them, and will relate to them more easily, if they are shaped like humans. It will be easier to be friends with human-shaped robots than with specialized machines of unrecognizable shape. And I sometimes think that, in the desperate straits of humanity today, we would be grateful to have nonhuman friends, even if they are only the friends we build ourselves.

All the hundreds of millions of people who, in their time, believed the Earth was flat never succeeded in unrounding it by an inch.

Self-education is a continuing source of pleasure to me, for the more I know, the fuller my life is and the better I appreciate my own existence

It is quite clear that as long as the nations of the world spend most of their energy, money, and emotional strength in quarreling with words and weapons, a true offensive against the common problems that threaten human survival is not very likely. A world government that can channel human efforts in the direction of the great solutions seems desirable, even essential. Naturally, such a world government should be a federal one, with regional and local autonomy safeguarded and with cultural diversity promoted.

The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."

Old men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight. They become accustomed to the more plodding varieties of reason, and because this is more than made up by the accumulation of experience, old men think themselves wiser than the young.

To me it seems to be important to believe people to be good even if they tend to be bad, because your own joy and happiness in life is increased that way, and the pleasures of the belief outweigh the occasional disappointments. To be a cynic about people works just the other way around and makes you incapable about enjoying the good things.
