I have no notions of a perfect society, I don’t know what that means. I know we can do much better than what we’ve got, I’m no utopian, I’m not a humanist that would like to see everybody living in warmth and harmony: I know that if we don’t live that way, we’ll kill each other and destroy the Earth.

We could either develop paradise on Earth or oblivion; wipe ourselves out, only the future will tell. It's what you do to make the future.

It’s your own expectations that hurt you. Not the world you live in. Whatever happens in the world is real. What you think should happen is unreal. So people are hurt by their expectations. You know , you’re not disappointed by the world, you are disappointed by your own projections.

To be human is to care for your fellow human beings and protecting the environment.

War is the supreme failure of bridging the differences between nations.

We can work out anything if we put our mind to it, study it, do hard work instead of finding simple answers

When they say all men are created equal, that bothers me. I told you some are thin, some are heavy, some have better eyesight than others. I don't know what that means. I think they're trying to talk about equal opportunity and I know that doesn't exist. If you don't have the money to go to college, the word 'equal opportunities' mean nothing
