art must have a purpose. that purpose is, more often than not, a promotion of certain values the author deems to be important for the society to be reminded of. promoting values is, inevitably, a political endeavor. and while it is possible for a work of art to promote values universally acceptable across the political spectrum, such art is generally quite banal. in fact, art that is not politically divisive usually does not have a value message at all, making it largely useless.
