The things that Picasso and I said to one another during those years will never be said again, and even if they were, no one would understand them anymore. It was like being roped together on a mountain.

In art, progress lies not in an extension, but in a knowledge of limitations.

I couldn't portray a woman in all her natural loveliness... I haven't the skill. No one has. I must, therefore, create a new sort of beauty.

The function of Art is to disturb. Science reassures.

Art upsets, science reasures.

I have made a great discovery. I no longer believe in anything. Objects don't exist for me except in so far as a rapport exists between them and myself. When one attains this harmony, one reaches a sort of intellectual non-existence, what I can only describe as a sense of peace, which makes everything possible and right. Life then becomes a perpetual revelation. That is true poetry.

One has to arrive at a specific temperature, at which the objects become malleable.
