Can Hegel really produce thoughts about aesthetics ?

Can Hegel really talk about aesthetics?
A few months ago, I glanced through an eye of the German idealist philosopher Georg Wilhelm Friedrich Hegel. From 1818 to 1829, he gave numerous lectures on aesthetics at the University of Heidelberg. These lectures were published in a book a few years later, in 1835. 
Something strucked me, when beginning the reading of this collection.
The book is an in-depth reflection on the aesthetics approached from a philosophical point of view. This reflection is intended to be independent, as usual, from the greatest number of cognitive biases and subjective opinions of the philosopher.
However,I have said to myself, Hegel has reflected so much on political thought and law, that his reflection on aesthetics can only be completely imbued with this scientific vision. Can he think on art as a person independent of this political and legal policy? The specificity of the political philosopher is, like the one of the french administrative judge *, that he or she tries to bring in almost any object of science within his field of scientific competence and, as the matter a fact, with brilliance.
Moreover, it is of course complicated to reflect on art by independent thought, even if Kandinsy does it in a work of 1911, "Of the spiritual in art and in painting in particular." Is the artist better placed than the philosopher-researcher to reflect on art? This is where Max Weber intervenes and his "axiological neutrality": the researcher can never be completely independent of his object of study. From then on, Hegel can not be completely independent open talks about taste. More applies to many professions. The specificity of Hegel is that it is a rational philosopher so political that he can not, in any case, understand the apolitical specificities of art and its perception.
Perhaps no political thinker can truly understand art without going through representations or explanations. The analysis is permanent, and the apoliticism which contains most of the works of which they are understandable only by a strictly political analysis.
