Um, that's a tough one for me. Like with music/art/architecture/things.. I also tend to be considerably eclectic and pick parts from expressed philosophies that I read about too.
(um, fav=one=?) Well, if I were to pick one off the top of my head now I'd say, Xenophanes.. and this, for his brilliant anthropomorphic god critique.
We know very little about the chap but he stating (read via others) that if one could hypothetically ask a horse to paint or describe, (if possible).. 'god' in 'its own wording/imagination'.. he thought a horse would describe/paint a big strong, rightful, honest, good virtued, etc.... horse.
(or other cattle members)
Others may subtract other broths from his, a bit more elaborating explanation, but to me it proves that.. yeah, not just beauty but.. ALL is in the eye of the beholder.
Um, searching for the truth here.. (thinking that's best.. )

If you had to choose between McDonalds, KFC, Burger King or let's say your local Chinese take away.. What would you pick?
