I believe the only hope for mankind lies in the hands of our young people.

Well, in some ways we're not successful at all. We're destroying our home. That's not a bit successful.

If you consciously say 'I won't do it!' to yourself, then you have a good chance that you won't.

We have a responsibility toward the other life-forms of our planet whose continued existence is threatened by the thoughtless behavior of our own human species. . . . Environmental responsibility – for if there is no God, then, obviously, it is up to us to put things right.

We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts. We can and we do. This is what sets us apart from the chimps. They are extremely brutal and hostile. Your next door neighbor is to be killed unless she is a juicy young female, who hasn't yet had her first baby, in which case you want her.

Words can be said in bitterness and anger, and often there seems to be an element of truth in the nastiness. And words don't go away, they just echo around.

Every stage of my life set the scene for the next, and at each point all I had to do was say "yes" and not think too much about the consequences.
