Art and Metaphysic
After the collapse of the general thesis of Idealism, however spirit is strictly one aspect of artworks....it is not in any way present without what is opposed to it (i.e. non-spirit). Constitutively, the spirit of artworks is not pure.
Only as spirit is art the opposite of empirical reality, which (qua this opposite) becomes the determinate negation of the existing world order.
