All good art is abstract in its structure.

To be a photographer you must have something to say about the world.

I think of myself as an explorer who has spent his life on a long voyage of discovery.

I like to photograph people who have strength and dignity in their faces. Whatever life has done to them, it hasn’t destroyed them.

I don't care how you photograph - use the kitchen mop if you must, but if the product is not true to the laws of photography... you have produced something that is dead. (1923)

Did I express my personality? I think that's quite unimportant because it's not people's selves but what they have to say about life that's important.

The existence of a medium, after all, is its absolute justification, if as so many seem to think, it needs one and all comparison of potentialities is useless and irrelevant. Whether a water-color is inferior to an oil, or whether a drawing, an etching, or a photograph is not as important as either, is inconsequent. To have to despise something in order to respect something else is a sign of impotence. [emphasis added] Let us rather accept joyously and with gratitude everything through which the spirit of man seeks to an ever fuller and more intense self-realization.
