“Then [speaking of his loosely figurative work of the 1930's, in Germany] I was still under nature, not that I was imitating it; now [1957] I am above nature. But everything comes from nature, I too am part of nature; my memory comes from nature, too.”

Address on sentencing (1885)
Context: I am contradicted at this moment on politics, and the smile that comes to my face is not an act of my will, so much it comes naturally, from the satisfaction that I prove that I experience seeing one of my difficulties disappearing. Should I be executed, at least if I were going to be executed, I would not be executed as an insane man, it would be a great consolation for my mother, for my wife, for my children, for my brothers, for my relatives, even for my protectors, for my countrymen. I thank the gentlemen who were composing the Jury for having recommended me to the clemency of the Court. When I express the great hope that I have just expressed to you, I don't express it without ground, my hopes are reasonable, and since they are recommended, since the recommendation of the Jury to the Crown is for clemency.

Attributed by Lee Krasner (1964) in " Oral history interview with Lee Krasner, 1964 Nov. 2-1968 Apr. 11 http://www.aaa.si.edu/collections/oralhistories/transcripts/krasne64.htm", interview with Dorothy Seckler for the Smithsonian Institution Archives of American Art.
In Krasner's words: 'When I brought Hofmann up to meet Pollock and see his work which was before we moved here, Hofmann's reaction was — one of the questions he asked Jackson was, do you work from nature? There were no still lifes around or models around and Jackson's answer was, 'I am nature.' And Hofmann's reply was, 'Ah, but if you work by heart, you will repeat yourself.' To which Jackson did not reply at all.'
