Searching is everything - going beyond what you know. And the test of the search is really in the things themselves, the things you seek to understand. What is important is not what you think about them, but how they enlarge you.

What I feel is that the picture-taking process, anyway a greater part of it, is an intuitive thing. You can't go out and logically plan a picture, but when you come back, reason then takes over and verifies or rejects whatever you've done. So that's why I say that reason and intuition are not in conflict-they strengthen each other.

Theoretical scientists who probe the secrets of the universe and philosophers who seek answers to existence, as well as painters such as Paul Klee who find the thoughts of men of science compatible with art, influence me far more than most photographers.

A thing is not what you say it is or what you photograph it to be or what you paint it to be or what you sculpt it to be. Words, photographs, paintings, and sculptures are symbols of what you see, think, and feel things to be, but they are not the things themselves.

The camera is not only an extension of the eye but of the brain. It can see sharper, farther, nearer, slower, faster than the eye. It can see by invisible light. It can see in the past, present, and future. Instead of using the camera only to reproduce objects, I wanted to use it to make what is invisible to the eye - visible.

There is nothing mysterious about space-time. Every speck of matter, every idea, is a space-time event. We cannot experience anything or conceive of anything that exists outside of space-time. Just as experience precedes all awareness and creative expression, the visual language of our photographs should ever more strongly express the fourth dimensional structure of the real world.

If you stop searching, you stop living, because then you're dwelling in the past. If you're not reaching forward to any growth or future, you might as well be dead.
