 But what happened to the question about the audience? “The soul” is not the addressee of a rhetorical discourse. Socrates responds that the artful rhetorician must also know what the types of soul are, what sorts of speeches “work” on each type, and be able to identify which type is being addressed on the given occasion. This last demand is a matter of practice and of the ability to size up the audience on the spot, as it were. The requirements of the true art of rhetoric, which Socrates also calls the “art of dialectic” (276e5–6), are very high indeed. (The reader will find them summarized at 277b5–c6).
