Nietzsche understands the aesthetic state of the observer and recipient on the basis of the state of the creator. Thus the effect of the artwork is nothing else than a reawakening of the creator's state in the one who enjoys the artwork. Observation of art follows in the wake of creation. Nietzsche says (SM, 821), —the effect of artworks is arousal of the art-creating state, rapture.
