That Hegel is a metaphysician, and that he thinks metaphysics is fundamental to philosophy, is plain enough from his definition of philosophy.

Schiller is an important philosopher because he shows just how integral the idea of beauty is in normal life.

Hegel remains of great importance to understand ourselves, but essentially because we have all grown out of a reaction against Hegel.

The romantics really did want to romanticise the world itself, and that meant re-creating the state, society and even nature so that it became a work of art.

When Hume insists that taste is a matter of delicacy, that it is a matter of having a sensitivity to features of an object itself, he is very close to the rationalist doctrine. Hume was really a covert objectivist (or partial one) about aesthetic pleasure because that pleasure had to be based on the sensitivity to features in the object.

The aesthetic dimension of the ideal state comes out in the idea of harmony, which is the classical idea of beauty as "concinnitas" or "unity-in-variety".

Liberals and leftists are not wrong in describing romanticism as reactionary, because it did indeed become that after 1810. The problem is that they make that description true of the movement as a whole, as if romanticism were essentially reactionary.
