Abstract

This paper examines the relationship between participation and motion with respect to the natural philosophy of the "Phaedo". Aristotle’s criticism of participation and its failure to account for motion shows the relevance of the dialogue to this problem. Challenging Aristotle’s critique, I interpret the "Phaedo" as offering a possible solution to the question of how forms cause motion in material beings. The verb ὀρέγεσθαι at 65c8, 75a2, and 75b1, together with the active ὀρέγειν at 117b2, ground an account of ontological striving as a solution to the difficulties inherent in participation within the literary context of the dialogue.
