Kant speaks of the "thing-in-itself" (Ding an sich) in order to distinguish it from the "thing-for-us" (Ding fur uns), that is, as a "phenomenon." A thing-in-itself is that which is not approachable through experience as are the rocks, plants, and animals. Every thing-for-us is as a thing and also a thing-in-itself, which means that it is recognized absolutely withing the absolute knowledge of God. But not every thing-in-itself is also a thing-for-us: God, for instance, is a thing-in-itself, as Kant uses the word, according to the meaning of Christian theology. p. 5

This is precisely what is decisive in Nietzsche’s conception of art, that he sees it in its essential entirety in terms of the artist; this he does consciously and in explicit opposition to that conception of art which represents it in terms of those who “enjoy” and “experience” it.
That is a guiding principle of Nietzsche’s teaching on art: art must be grasped in terms of creators and producers, not recipients. Nietzsche expresses it unequivocally in the following words (WM, 811): “Our aesthetics heretofore has been a woman’s aesthetics, inasmuch as only the recipients of art have formulated their experiences of ‘what is beautiful.’ In all philosophy to date the artist is missing.” Philosophy of art means “aesthetics” for Nietzsche too—but masculine aesthetics, not feminine aesthetics. The question of art is the question of the artist as the productive, creative one; his experiences of what is beautiful must provide the standard.

Enjoyment of the work consists in participation in the creative state of the artist.
