Abstract

Over time, Aristotle’s theory of four causes lost some of their original flexibility as an instrument to be applied analogically in diverse sciences. Enrico Berti’s distinction between physical and metaphysical causality in Aristotle provides insight into overcoming this crystallization. More importantly, the novelty of Aquinas’ metaphysics of actus essendi calls for a revision of the four causes: first, actus essendi is presented as actuating act and the source of the finite being’s ordered operation; the substantial essence falls to potency and specifies the act of being; the efficient cause is the power of God insofar as he produces and moves the creature; divine exemplar causality is twofold ; the final causality concerns both the order and the governance of the world. In this paper, then, I outline this analogical passage from Aristotle’s physical causality to Aquinas’ metaphysical causality in reference to their modern interpreters, like Enrico Berti and Jan A. Aertsen.
