Art for Art's sake or for Society's

I like aesthetically pleasing art. But I feel that art that can benefit another person in some way is more important. That's not to say that society benefiting art can't be aesthetically pleasing but that it's not the focus. Art for Art's sake being about the aesthetic doesn't mean it's "pretty" either. Personally I fail to see the beauty in a painted square on a large canvas. Art that conveys a message, that transforms the viewer is more powerful and takes more thought into what's being put on the canvas or whatever medium you use to showcase your work. The word art was originally thought of as a verb. Art that benefits society does something, an action, acts as a verb. I personally lean more towards the ideas of art for society's sake.
