First, this is an economics class and I think it's great that they're reading such diverse authors. But I also think the professor uses Rorty in an interesting way. You get the impression that he's going to use Rorty to talk about Marxist views about how social class affects peoples' perspectives on the world. He does allude to that briefly, but then goes in a different direction. Where he ends up is using Rorty to talk about how, despite the protestations of some Marxists there is no "true Marxism" because everyone in history who has influenced or discussed the conceptual object of Marxism has had their own social context that colors their relationship with Marxism and thus produces different claims about what Marxism "really" is.
Jets apparently like to snort a bit too
