Seeing is in itself a movement.

The auditory perception is not sufficient for our knowledge of the world; it does not have vastness.

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

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

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.

I say it is indispensable to look ahead of and behind oneself in the present. If there is such a thing as tradition, and I believe there is, it can only exist in the sense of the most profound movements of culture.

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.
