The Accident and its Causes: Pseudo-Alexander on Aristotle (Metaphysics E 3)

Pseudo-Alexander’s commentary in Metaphysics Ε 3 is one of the three ancient commentaries which came down to us together with Ascepius’s commentary and Pseudo-Philoponus’s one, in Latin. Pseudo-Alexander’s work, in particular, constitutes the source of interpretation of the Aristotelian text for many modern scholars. In chapter 3 Aristotle shows that there are causes of accidental being, which are generable and destructible without ever being in course of being generated or destroyed. This problem is one of the most difficult and controversial for Aristotle. The thesis is explained by Aristotle with examples concerning past and future events. Pseudo-Alexander considers them as referring to accidental causes. The exegete’s explanation of both cases introduces some elements which are totally extraneous to the Aristotelian text, but nevertheless it could be helpful to cast some light on the understanding of the most controversial passages. In the final passage, Aristotle raises the question of what kind of cause the accident leads to, whether to the material or to the final or to the efficient cause. It is apparently left without an answer. Pseudo-Alexander gives a plausible solution, which is nonetheless probably only partial. The chapter was also examined with reference to the problem of determinism in Aristotle.
