The only things that distinguish the photographer from everybody else are his pictures: they alone are the basis for our special interest in him. If pictures cannot be understood without knowing details of the artist's private life, then that is a reason for faulting them; major art, by definition, can stand independent of its maker.

Art depends on there being affection in its creator's life and an artist must find ways, like everyone else, to nourish it. A photographer down on his or her knees picturing a dog has found pleasure enough to make many things possible.

When photographers get beyond copying the achievements of others, or just repeating their own accidental first successes, they learn that they do not know where in the world they will find pictures. Nobody does. Each photograph that works is a revelation to its supposed creator.

Among the most compelling truths in some of the early photographs is their implication of silence.

We rely, I think, on landscape photography to make intelligible to us what we already know.

... If we consider the difference between William Henry Jackson packing in his camera by mule, and the person stepping for a moment from his car to take a picture with his Instamatic, it becomes clear how some of our space has vanished; if the time it takes to cross space is a way by which we define it, then to arrive at a view of space 'in no time' is to have denied its reality.

We cannot empty the mind by thinking. Only by observation.
