Substantial Form?

One of the things I have learned recently is that the common scholastic (but post-Aristotelian) notion of substantial form goes back at least to Averroes. Aristotle talks separately about form and about substance, but never combines them in a single phrase like “substantial form”.

One of the important meanings of “substance” (ousia) is indeed form-like, as when he speaks of the what-it-is of things. Aristotle presents this meaning as superseding its more syntactic meaning of “underlying thing”. But eventually, this too is superseded by the uniquely Aristotelian notion of “act” (energeia), about which I have written much in the past year.

I’m now curious whether something like “substantial form” makes any appearance in the neoplatonic commentators like Simplicius and Philoponus. As Platonists, they would have an interest in turning the interpretation of substance back in the direction of form. (See also Substance, Essence, Form).
