 His conversation with Socrates falls into three parts, covering idiosyncrasy (530a–533c), inspiration (533c–536d), and ignorance (536d–542b). Both the first and the third sections support the claims made in the second, which should be seen as the conclusion to the dialogue, supported in different ways by the discussions that come before and after it. The idiosyncrasy in Ion’s attachment to Homer shows that Homer, and Ion because of him, function thanks to a divine visitation. But because Ion resists accepting a claim according to which he is deranged in his performances, Socrates presents a fall-back argument. Ion is unqualified to assess any of the factual claims that appear in Homer, about medicine, chariot racing, or anything else. When Socrates compels him to choose between divine inspiration and a very drab brand of knowing nothing, Ion agrees to be called inspired.
