What is the point of art?

For several years now, I have just been posting images of my paintings without writing much about them. I think I need to change this. I need more writing. I haven't done much writing because I never thought of myself as a writer and imagined that my paintings spoke for themselves. But they probably don't, at least on the internet. I may start a whole new blog where I discuss color or try to figure out what the point of art is. The attached images are four 6" square paintings that I am working on. They are a departure for me - into the realm of abstract - with no source material outside of my own mind. Comment if you think you know what the point of art is. Ann
