When I see an old movie, like from the ’40s or ’50s or ’60s, the people look so calm. They don’t have smartphones, they’re not looking at computer screens, they’re taking their time. They’ll sit in a chair and just stare off into space. I think some day we’ll find our way back to that garden of Eden.

I like a book better if I can't predict what's going to happen.

At present, however, I don't think the Net is a very good medium for books, books should really be inexpensive lightweight paperbacks you can bang around.

Intellectually, perspective [drawing] is a breakthrough, because here, for the first time, the physical space we live in is being depicted as ifit were an abstract, mathematical space. A less obvious innovation due to perspective is that here, for the first time, people are actually drawing pictures of infinities.

What is the shape of space? Is it flat, or is it bent? Is it nicely laid out, or is it warped and shrunken? Is it finite, or is it infinite? Which of the following does space resemble more: (a) a sheet of paper, (b) an endless desert, (c) a soap bubble, (d) a doughnut, (e) an Escher drawing, (f) an ice cream cone, (g) the branches of a tree, or (h) a human body?

Selling a book or story has never become absolutely automatic for me.

The world is magic. Science is but an insipid style of sorcery.
