Denis Dutton thinks we're Hardwired to seek beauty. I think so too, I guess, though I'm bothered by the term hardwired. It's a metaphor, of course, but it presumes that one of the essential notes of actual hardwiring -- someone to do it -- is absent. I am likewise bothered when someone compares the world to a machine -- but on the assumption that there's no mechanic to go with it. An actual machine without an actual mechanic is something we have no experience of.
