Thomas Aquinas on Assimilation to God through Efficient Causality
This article is a contribution to the field of study that Jacques Maritain once described as ¡°metaphysical Axiomatics.¡± I discuss Aquinas¡¯s use of the metaphysical principle ¡°omne agens agit sibi simile,¡± focusing on perhaps the most manifest instance of this principle, namely, univocal generation. It is well known that Aquinas holds what could be called a ¡°static¡± or ¡°formal¡± view of likeness between God and creatures: creatures are like God because they share in certain exemplar perfections that preexist in God. My focus instead is on an efficient likeness to God, which reflects a foundational truth about reality for Aquinas: all creatures produce something like themselves through their operations, in imitation of God, who does so on a more fundamental level. My discussion will also clarify Aquinas¡¯s derivation of the principle of similitude from a prior metaphysical principle, ¡°every agent acts insofar as it is in act.¡±
