Why Art?

Why do artists make what they make? Do we have different brains? We know that there are specific personality traits that artists share (see Getzels and Csikszentmihalyi) and that each medium has traits specific to that medium.

And what is it about the appreciation of art? Why are some drawn to colors and others to form? And why one form over another? What is it about the work of Pollok and other non-objective painters that turns people off? And in a big way too.. I have had many voice rather hostile opinions about this sort of work.. Pollock's in particular. A lack of education in the arts explains some of that, but not all.

I see creativity manifested in art. It expresses something that otherwise is left unexpressed. But why? Is it that there simply are no words for some things, like feelings and emotions and all that sort of thing? It's almost as if another language exists out there and art is the only means of expressing it.

These questions may not be new to art and aesthetics, but in the context of creativity research there is a great deal the two fields can laern from each other.
