A Thing Of Beauty

Brilliant post over at Prof Ed Feser's blog applying Aquinas's criteria of beauty to the movie of David Mamet's Glengarry Glenn Ross brought to my mind the realisation that Joyce's application of the same terms in A Portrait remains the single most coherent explanation of what constitutes 'art' I've ever read. I suppose I could say of myself with regard to the whole realm of aesthetic theory that this is all I know and all I'll ever need to know.
