"I should like all artists to sell their fingerprints, or else stage competitions to see who can draw the longest line or sell their shit in tins. The fingerprint is the only sign of the personality that can be accepted: if collectors want something intimate, really personal to the artist, there's the artist's own shit, that is really his."

“The work of art has its origin in an unconscious impulse that springs from collective substrata of universal values common to all men, from which all men draw their gestures, and from which the artist derives the 'archaic' of organic existence. Every man of his own accord extracts the human element from this base, without realizing it, and in an elementary and immediate way.”

“So it is obvious that at first glance there would seem to be a paradox: the more we immerse ourselves in ourselves, the more open we become, since the closer we get to the germ of our totality the closer we are to the germ of totality of all men.

“When I blow up a balloon, I am breathing my soul into an object that becomes eternal.”

“The foundations of the universal value of art are given to us now by psychology. This is the common base that enables us to sink its roots to the origins before man and to discover the primary myths of humanity. The artist must confront these myths and reduce them, by means of amorphous and confused materials, to clear images. Since these are atavistic forces that have their origins in the subconscious, the work of art takes on a magical significance.”
