beauty = whatever happens to trigger the ‘oooh’ feeling in a Desire player. This would be a perfectly sensible definition: if something appeals to you, it’s beautiful, end of story. This is the kind of beauty that people say is “in the eye of the beholder,” where each creature develops its own subjective tastes. The dung beetle can find dung “beautiful” while we find it disgusting, and there would be no tension whatever between these two facts.
Beautiful!
