Platonist's Treatise on Beauty

Platonist aesthetics links up with the ideas we were talking about about imitation and also with his theory of beauty. The idea that beauty in the physical world can be of value spurs us on to eventually not having an understanding of the form of beauty. Proclus was critical of the stoic idea that beauty is simply to do with symmetry of parts he says no it isn't that it comes from somewhere outside the physical world.
