All good art is abstract in its structure.

It has always been my belief that the true artist, like the true scientist, is a researcher using materials and techniques to dig into the truth and meaning of the world in which he himself lives; and what he creates, or better perhaps, brings back, are the objective results of his explorations. The measure of his talent--of his genius, if you will--is the richness he finds in such a life's voyage of discovery and the effectiveness with which he is able to embody it through his chosen medium.

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)

All good art is abstract in its structure.

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.

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

Whether a watercolor is inferior to an oil [painting], 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.
