I've been trying to fill some of the gaps in my college education recently, and I thought it would be good to do some reading up on art theory/criticism/opinions. I know we've got a handful of extremely well-read artists here so I was hoping you'd be willing to share a few choice books to start me off in the right direction. Not so much interested in technical books, but rather the theory behind art itself. Some of that obnoxiously heady stuff.
Thanks in advance.
