Philosophy of Art

Hi David

Thanks for the reference. I shall see if I can track it down.

I should explain that my comment on duende was meant a little flippantly. I didn't really want to suggest that one could answer "what is art?" with "art is duende". In part I was taking the opportunity to have another dig at the "art is beauty" thesis - one of my pet aversions.  (But it's a thesis that dies so hard! Scruton has a newish book on it that I keep seeing in bookshops and, at the other end of the philosophical spectrum, I even stumbled on a recent book by Jean-Luc Nancy where he trots out the same old warhorse. And there are legions of others.)

I'll be in contact off list about the research idea.
