We are all the subjects of impressions, and some of us seek to convey the impressions to others. In the art of communicating impressions lies the power of generalizing without losing the logical connection of parts to the whole which satisfies the mind.
The purpose of the painter is simply to reproduce in other minds the impression which a scene has made upon him. A work of art does not appeal to the intellect. It does not appeal to the moral sense. Its aim is to instruct, not to edify, but to awaken an emotion.
The true end of art is not to imitate a fixed material condition, but to represent a living motion.
