"In Art we know nothing for certain."

“There is no difference between landscapes and other subjects: in general in painting I try to express the emotions that the contemplation of the form produces in me.”

“A work of art is a work of art, and nothing else, personal considerations count for nothing.”

“My paintings do no more than give an idea of my wanderings in search of a guiding principle in art”

“It was inevitable that artists should turn around and question the validity of the fundamental assumption that art aimed at representation; and the moment the question was fairly posed it became clear the pseudo scientific assumption that fidelity to appearance was the measure of art had no logical foundation.”

“As I understand it, art is one of the chief organs of what, for want of a better word, I must call the spiritual life.”

“Only those who have experienced the elation and despair which comes from the attempt to express their feelings about vision in oil paint will know that it is impossible to speak with complete impartiality about art.”
