I think that in free societies, and we're constantly talking about living in free societies, aren't we, in contradiction with unhappy people who live in non-free societies, that the benefit, the dividend of living in a free society is that you say what you think.

I don't think that it would make the slightest difference to life and to the aspects of life that interest me if we could go to the moon tomorrow, because I think what really makes life interesting is the big question "Why?"

All of us admire people we don't like and like people we don't admire.

As an old man...looking back on one's life, it's one of the things that strikes you most forcibly-that the only thing that's taught one anything is suffering. Not success, not happiness, not anything like that. The only thing that really teaches one what life's about...is suffering, affliction.

Every happening, great and small, is a parable whereby God speaks to us, and the art of life is to get the message.

I don't like seeing people angry.

I think that once you've produced a conformist, a totally conformist society, a society in which there were no critics, that would in fact be an exact equivalent of the totalitarian societies against which we are supposed to be fighting in a cold war.
