The struggle against subjectivism was the attempt to avoid the charge of what was then called "idealism" or "nihilism", i.e., that we know nothing more than our own representations.

The connection between romantic politics and aesthetics is plain in Schiller's and Novalis's concept of the aesthetic or poetic state.

The great German idealists from Kant to Hegel saw this idealism or nihilism as a reductio ad absurdum of any philosophy, and so they struggled by all conceptual means to avoid it.

Royce is the father of the thesis that German idealism is a story about the discovery and development of the Kantian transcendental ego - the "I" that accompanies all my representations - as an absolute cosmic supersubject who, god-like, creates the entire universe.

The idea of romanticising the world goes back to the idea of creating a harmonious whole where the individual will feel at one with himself, others and nature.

Since substance is infinite, the universe as a whole, i.e., god, Hegel is telling us that philosophy is knowledge of the infinite, of the universe as a whole, i.e, god. You cannot get more metaphysical than that. I think that Hegel scholars have to admit this basic fact rather than burying their heads in the sand and trying to pretend that Hegel is concerned with conceptual analysis, category theory, normativity or some such contemporary fad.

There is a sinister anachronistic interpretation of the aesthetic state as some kind of totalitarian regime that puts aesthetic over moral standards; one associates it with national-socialism. But this has nothing to do with the romantics, whose ideal of the aesthetic state has much more to do with the republican tradition.
