Homer plays an important role in the discussion in the Hippias Minor of voluntary and involuntary action and their relation to knowledge and goodness. This paper argues that the Hippias Minor sheds light on the Homeric criticism of the late fifth and early fourth centuries, and that it looks forward to, and significantly influenced, the tradition of Hellenistic and later Homeric criticism, for which our best witnesses are the Homeric scholia. This paper considers Socrates' presentation of Achilles and Odysseus in the Hippias Minor and makes the case, more strongly than it has been made before, that this dialogue was an important influence on the later critical tradition.Homer plays an important role in the discussion in the Hippias Minor of voluntary and involuntary action and their relation to knowledge and goodness. Unlike the Ion, to which it bears in some ways a striking resemblance, and not merely in the manifestly parodic presentation of the eponymous figures of the two dialogues, 1 poetry and performance are not the principal subjects of the Hippias Minor. However, this dialogue arguably sheds as much or even more light on the Homeric criticism of the late fifth and early fourth centuries as does the Ion, and -again like the Ion -it looks forward to, and significantly influenced, the rich tradition of Hellenistic and later Homeric criticism, for which our best witnesses are the Homeric scholia. 2 In this paper, I want both to consider how Plato 3 presents Socrates' treatment of Achilles and Odysseus in the Hippias Minor and also to make the case more strongly than it has been made before that this dialogue was an important influence on the later critical tradition. 4
