Monet is only an eye, but my God, what an eye!

Optics, developing in us through study, teach us to see.

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.

I lack the magnificent richness of color that animates nature.

Painting from nature is not copying the object; it is realizing one's sensations.
