Read it through once

The emotion may be transformed, or it may be expressed less perfectly—on account of the limitation of the individual's experience, or because of his confusion of himself with the emotion; but the worth of the emotion in art is not dependent upon the extent or peculiar quality of the individual's direct personal experience. The activity of an artist often appears to us like the activity of another kind of mind. The artist is, in fact, a critic of his own emotions.
