It's typical to say that there's no such thing as an "objectively" good piece of art. But if that were so, why would we even bother sharing our thoughts about it? What would be the point in discussing a movie or song or painting with other people if we really thought that all our opinions were ultimately arbitrary? In other words, is there any way to make sense of the way we commonly talk about art that doesn't imply at least some kind of objectivity?
