Sometimes I imagine colors as if they were living ideas, being of pure reason with which to communicate. Nature is not on the surface, it is deep down.

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

People think how a sugar basin has no physiognomy, no soul. But it changes every day.

See nature in terms of the cone, the cylinder, and the sphere.

I'll always be grateful to the public of intelligent amateurs.

The day is coming when a single carrot, freshly observed, will set off a revolution.

I have to keep working, not to arrive at finish, which arouses the admiration of fools... I must seek completion only for the pleasure of being truer and more knowing.
