Truth is eternal. Knowledge is changeable. It is disastrous to confuse them.

The only way to cope with something deadly serious is to try to treat it a little lightly.

We don't want to feel less when we have finished a book; we want to feel that new possibilities of being have been opened to us. We don't want to close a book with a sense that life is totally unfair and that there is no light in the darkness; we want to feel that we have been given illumination.

When I have something to say that I think will be too difficult for adults, I write it in a book for children. Children are excited by new ideas; they have not yet closed the doors and windows of their imaginations. Provided the story is good... nothing is too difficult for children.

With our human limitations we're not always able to understand the explanations.

I'm apt to get drunk on words...Ontology: the word about the essence of things; the word about being.

I hope that I will never forget the salvific power of joyful laughter.
