In Plato's Republic, Glaucon tells a story about Gyges' ring that, on the surface, suggests a radical opposition between appearances and truth. We argue that, contrary to Glaucon's intentions, what his story actually reveals is that appearances are always and inevitably implicated in the attempt to tell the truth about justice or the soul. This mutual implication is confirmed by Glaucon's own commentary on his story as well as by Socrates' arguments about the city and the soul. We argue that knowing the soul “in itself” requires that one examine it not by itself, but as it is immersed in human life. It is a question of how the soul “looks” – meaning not simply how it seems or appears, but of where it is looking, or what it desires. Taking its looks into account, in this sense, is very different from being taken in by appearances. We explore the implications of this idea for the possibility of attaining philosophical knowledge about justice, and for the relationship between philosophy and politics.
