The Ion (Greek: Ἴων) is a dialogue in which Socrates discusses the nature of poetry with a rhapsode, a professional performer who specialises in giving oral recitations from Homer. Socrates questions whether his ability is the result of skill or divine inspiration.
The dialogue is a key example of Plato's suspicion of mimesis or imitation. It could also be seen as a critique of the place of oral tradition in Greek culture, although as the Phaedrus shows, Plato also had doubts about the advantages of writing.
