Every page must explode, whether through seriousness, profundity, turbulence, nausea, the new, the eternal, annihilating nonsense, enthusiasm for principles, or the way it is printed.

I do not consider myself a Cubist either because I have come to the conclusion that cubes are not always made for expressing the thought of the brain and of the feeling of the spirit.
I capture all these impressions without any hurry to transfer to the canvas. I let them rest in my brain and then, when I’m visited by the spirit of creation, I improvise my paintings just as a musician improvises his music.
