 Despite his reservations, Aristodemus agrees to accompany Socrates—but with an important proviso: “See what defense you’re going to make (apologêsê) for bringing me along, because I won’t admit I came uninvited, I’ll say you brought me!” (174c7-d1). It is this proviso that initiates the next mystifying episode. It begins when Socrates replies by under-quoting Homer: “We’ll take counsel about what to say ‘when two go together along the way’” (174d2–3). What he leaves out is what happens when two do go together, namely, “one of them knows before the other” (Iliad X. 24). The elision of this phrase is matched by an elision of Plato’s own. For what happened on the road to Agathon’s is that “Socrates began to think about something, lost himself in thought, and kept lagging behind” (174d4–7). Yet we are never told what he thought about—what it was that one knew before the other.
