According to the metaphysical interpretation, art presents objects in nature such as rivers, but this presentation is at the service of something else, of their "meaning" in the artwork. Heidegger speaks in this regard of the etymology of the words "allegory" and "metaphor." The metaphysical interpretation of art relies on the distinction between the sensuous and the non-sensuous, the aesthetic and the noetic, the sensible and the intelligible. And according to this interpretation the artwork exists not for itself, not "as" a sensuous object, but "for" the nonsensuous and suprasensuous, which is also named "spirit." In this way the superior and the true come to be identified with the spiritual.
