Abstract
The main goal of this paper is tocompare how Thomas Aquinas expressedhis doctrine of providence through second-ary causes, making use of both Aristotelianand Neo-Platonic principles, in the seventharticle of the third question of his
Quaes-tiones Disputatae De Potentia Dei
and his
Super Librum de Causis Expositio
, in whichhe intends to solve the problem of themetaphysical mechanism by which God
providentially guides creation. I will rst
present his arguments as they appear inthe disputed questions, followed by a pre-sentation of his thought on the matter inhis commentary of the
Liber de Causis
, andconcluding with my comparative analysisof Aquinas’ solution to the issue of God’sprovidential activity in nature.
