Abstract

In this paper I show that Aristotle’s widely criticised exclusion of Platonic efficient causes at Metaph. A 6.988a7–17 is defensible as an interpretation of Plato, and that alternative accounts are unpersuasive. I argue that Aristotle is only interested in – what he supposes to be – Plato’s first principles and that the usual candidates that are brought forward in scholarship as possible first principles and efficient causes (e.g. from the Timaeus and the Philebus) all fall short in crucial respects according to Aristotle. This reading has the dual benefit of illuminating Aristotle’s strategy in book A and of letting him appear as a more trustworthy doxographer of his predecessors’ views.
