"My whole ambition in the pictorial domain is to materialise the images of concrete irrationality with the most imperialist fury of precision. - In order that the world of the imagination and of concrete irrationality may be as objectively evident.. ..as that of the exterior world of phenomenal reality. - The important thing is what one wishes to communicate: the concrete irrational subject. - The means of pictorial expression are placed at the service of this subject."
