By offering a fresh reading of several partially overlooked passages from Aristotle’s Metaphysics Μ and Ν, this article argues that the identification of Forms and ideal numbers in Plato is not presented as Aristotle’s own reconstruction. Instead, Aristotle sets forth what he takes to be Plato’s views. This reading enhances not only our understanding of the Academic debates with which Aristotle engaged but also his status as a historian of philosophy.
