If I think, I am lost.

For an Impressionist to paint from nature is not to paint the subject, but to realize sensations.

Art is a harmony parallel with nature.

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

Doubtless there are things in nature which have not yet been seen. If an artist discovers them, he opens the way for his successors.

There are two things in the painter, the eye and the mind; each of them should aid the other.

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.
