Art helps to get to fundamental aspects of the mind which can't be reached in other ways. Sometimes I think of it is a way to understand what's going on when it's to complex to name or categorize.

It can also be a way to say things which are too hard to say outright like is done with comedy.

I like it as the result of the creative impulse. Sometimes nothing is meant by it but it hits a button for someone else. It's a lot better at this than random chance so I feel it's worthwhile.
