Another take on the old "What Is Art?" question

A friend of mine, Paul Butzi, is a photographer. You can see some of his excellent work at his website. He also has a blog there, where he posted this interesting musing on whether the question "What Is Art?" is worth asking at all. Essentially it boils down to what he calls "Paul's Rule": "never ask a question unless you're going to change your behavior based on the answer." He wouldn't stop making photography if it turned out it wasn't art, so perhaps it's not important to know the answer. There's a great story in his post about Jean-Pierre Rampal and a mockingbird, so go read it.
