Direct observation of the luminous essence of nature is for me indispensable

Human vision is endowed with the greatest Reality, since it comes to us directly from the contemplation of the Universe.

I am very much afraid of definitions, and yet one is almost forced to make them. One must take care, too, not to be inhibited by them.

Nature engenders the science of painting

It is this research into pure painting that is the problem at the present moment. I do not know any painters in Paris who are really searching for this ideal world.

Light comes to us by the sensibility. Without visual sensibility there is no light, no movement.

But what I attach great importance to is observation of the movement of colors. It is only in this way that I have found the laws of complementary contrast and the simultaneity of those colors that nourish the rhythm of my vision. There I find the representative essence — which does not arise from a system or an a priori theory.
