Two sittings a day of my models and I'm totally exhausted.

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.

The truth is in nature, and I shall prove it.

Is it the factitious and the conventional that most surely succeed on earth and in the course of life?

An art which isn't based on feeling isn't an art at all... feeling is the principle, the beginning and the end; craft, objective, technique - all these are in the middle.

You must think. The eye is not enough; it needs to think as well.

Everything vanishes, falls apart, doesn't it? Nature is always the same but nothing in her that appears to us lasts. Our art must render the thrill of her permanence, along with her elements, the appearance of all her changes. It must give us a taste of her Eternity.
