In this chapter, I provide an interpretation of the famous claim at the end of the Symposium that “the same man” ought to be able to write both comedy and tragedy, and a speculative reconstruction of the arguments that Socrates might have used to secure that claim in his discussion with Agathon and Aristophanes. I argue that ideal comedy and tragedy are unified in at least three ways. First, they constitute a teleological unity, in that their ethical imitations both aim at moral improvement; second, they constitute an ethical unity, in that they both rely on, and endorse, a single theory of value, according to which wisdom and virtue are good and ignorance and vice are bad; and third, they constitute an epistemic unity, in that the objects that they imitate – ridiculousness and seriousness in agents and actions – form opposite parts of the same branch of knowledge, such that one cannot know one without knowing the other. I further argue that actual comedy and tragedy are unified but in a much weaker sense that does not involve any knowledge. In the end, I discuss the possibility of tragicomedy and consider in what sense it might be correct to understand Plato’s dialogues as tragicomedies.
