 At this point Socrates introduces a strikingly unique feature of the dialogue, the Questioner—someone who, Socrates says, will not allow him to get away with claims that imply knowledge, but persists in asking him shame-inducing questions such as this one about defining to kalon. Since the Questioner meets Socrates in the privacy of his home, we must imagine that he is Socrates’ alter ego, and that the process referred to is the self-elenchus by which Socrates is driven to his famous disclaimer of knowledge.
