An artist must not feel under any constraint.

To arrive is to be in prison.

The essential thing is to spring forth, to express the bolt of lightning one senses upon contact with a thing. The function of the artist is not to translate an observation but to express the shock of the object on his nature; the shock, with the original reaction.

A new painting is a unique event, a birth, which enriches the universe as it is grasped by the human mind, by bringing a new form into it.

Time extracts various values from a painter's work. When these values are exhausted the pictures are forgotten, and the more a picture has to give, the greater it is.

Drawing is of the Spirit and color of the Senses.
