I am more a friend of art than a producer of painting.

Here, on the river's verge, I could be busy for months without changing my place, simply leaning a little more to right or left.

Everything in nature takes its form from the sphere, the cone and the cylinder.

There is a logic of colors, and it is with this alone, and not with the logic of the brain, that the painter should conform.

Art first of all is optical. That's where the material of our art is: in what our eyes think.

Nature is more depth than surface, the colours are the expressions on the surface of this depth; they rise up from the roots of the world.

The artist must scorn all judgment that is not based on an intelligent observation of character. He must beware of the literary spirit which so often causes a painting to deviate from its true path - the concrete study of nature - to lose itself all too long in intangible speculations.
