“In a mad world, only the mad are sane.”

“I suppose all of my films have a common theme. If I think about it, though, the only theme I can think of is really a question: Why can’t people be happier together?”

“No matter where I go in the world, although I can't speak any foreign language, I don't feel out of place. I think of earth as my home. If everyone thought this way, people might notice just how foolish international friction is and they would put an end to it.”

“People today have forgotten they're really just a part of nature. Yet, they destroy the nature on which our lives depend. They always think they can make something better. Especially scientists. They may be smart, but most don't understand the heart of nature. They only invent things that, in the end, make people unhappy. Yet they're so proud of their inventions. What's worse, most people are, too. They view them as if they were miracles. They worship them. They don't know it, but they're losing nature. They don't see that they're going to perish. The most important things for human beings are clean air and clean water.”

“Man is a genius when he is dreaming.”

“To be an artist means never to avert one's eyes.”

“Although human beings are incapable of talking about themselves with total honesty, it is much harder to avoid the truth while pretending to be other people. They often reveal much about themselves in a very straightforward way. I am certain that I did. There is nothing that says more about its creator than the work itself.”
