I am generally someone who is very interested in art and am planning to pursue a career in art, but I believe that we cannot "learn" from art because it cannot generate truth. It cannot be truth, it can only imitate a previously discovered truth. I guess the main focus here would have to go beyond art and instead define what exactly is learning, truth, or knowledge. If you apply Plato's a,b,c,d chart artists create an imitation of "a" -which is the sense experience of a reality we cannot know and that is not real. Plato would say artists are the furtherest away from "d" which is the ulitmate nature of reality. I'm really wondering what anyone else thinks.
