It is certain that at certain times talent entirely overcomes thought or poetry.

'Impressionism' was the name given to a certain form of observation when Monet, not content with using his eyes to see what things were or what they looked like as everybody had done before him, turned his attention to noting what took place on his own retina (as an oculist would test his own vision).

I don't dig beneath the surface for things that don't appear before my own eyes.

A portrait is a painting with something wrong with the mouth.

You can't do sketches enough. Sketch everything and keep your curiosity fresh.
