Has anyone written on the subject of art? More specefically tried to define it to include good works of such as Beethoven and exclude 50 cent? I'm trying to argue against the moral relativists
Yeah there is an ENTIRE philosophy field called Aesthetics.
Lessing - Laocoön
Kant - Critique of Judgement
Schlegel/Mendelssohn write some stuff on it
Adorno - Aesthetics
Deleuze has multiple works on the subject
