 It may well be that what Ion understands about Homer happens to hold true of Hesiod. But if this is the case, Ion will not know it. He does not generalize from one to many poets, and generalizing is the mark of a professional. Diotima’s speech in the Symposium supplies a useful comparison. She differentiates between love that clings to particular objects and a philosophical erôs that escapes its attachment to particulars to pursue general knowledge (210b). Ion’s investment in Homer, like the lover’s lowest grade of attachment, reveals (and also causes) an unwillingness to move toward understanding.
