Question re: internal diversity of substantial form

[tjgd...@ucalgary.ca]

Hi everyone:

I'm currently doing some research on Aquinas' views concerning the
internal diversity of substantial forms. That is, most substantial forms
seem to somehow incorporate distinct elements/characteristics/attributes.
We see this internal diversity even in the case of the most basic forms,
those of the elements. So the substantial form 'water', for instance, is
a union of two diverse principles, wetness and coldness. And these
principles seen to have no intrinsic conceptual connection to each other
(hence coldness can also be a constituent of earth). So how to account
for their unity?

I've found quite a lot of material on this question in recent scholarship
on Aristotle, but haven't seen much secondary literature concerning
Aquinas' views. And outside of some sections of "On Spiritual Creatures",
and some stuff in his commentary on the Metaphysics, I'm not sure where
else to look in Aquinas' own writings. Any suggestions concerning places
to look, whether in the primary or secondary literature?

Please reply off-list.

Thanks very much,
