I'm not looking to have a debate on stackexchange about wether aesthetics is a branch in itself.
However, I am looking for sources, or just recommendations of writers of aesthetics, who view Aesthetics as an application of other parts of Philosphy, rather than a branch in itself. For example, Ethics is (fairly undisputedly) an independant, generically (in general terms) studied field of Philosophy which can be applied to a diverse range of actual situations. By contrast, the Philosphy of Medicine is a application of Epistimnology, Philsophy or mind, Philosophy of Psychology and Ethics (among other fields) to medical problems. The difference is in the common ground. For a field of philsophy, the common ground is the type of problem studied, or perhaps the approach, for an application, the common ground is the content of problem, regardless of type.
Ideally, books/articles/papers conrtasting the two viewsof aesthetics are perfect, but those which put the view either view specifically are also fine.
Note: I ask for the view in the title as it appears to be less comon, but articles which specifically but the other view are also acceptable.
