Sibelius, Beethoven, Satie, Debussy
I don't agree that SM is defining art solely to suit himself. The ontology of Art is hard, but at the end of the day, we can all decide for ourselves what the word means and what art objects should be included or excluded. If all this deciding works for philosophers over the years, there's no reason why we can't do it too.Multiple practical approaches and the absolute freedom of a listener I accept but not fundamental ontological claims motivated solely by convenience of an individual. Ontology is hard science.
