How Augustinian Is Aquinas's Basic Account of Free Decision?

How Augustinian Is Aquinas's Basic Account of Free Decision? Jamie Anne Spiering Introduction Questions about Augustine's influence on Thomas Aquinas are always interesting. In the previous century, leading Thomists such as Marie Dominic Chenu, Jean-Pierre Torrell, and Étienne Gilson wrote about the influence of one great master on the other. However, no one thinks the investigation is complete: the contributions of the new century have begun and are expected to continue.1 In this article, I would like to consider how Augustine influenced Aquinas's account of something known to both authors as liberum arbitrium: free choice, or free decision.2 When we speak of grace and End Page 435 human freedom, Aquinas's debt to Augustine and the extent of his fidelity to the master have been frequently explored.3 The same is true with regard to the fairly advanced question of the relation between human freedom and divine foreknowledge.4 But in this article I would like to consider Thomas's treatment of what we might call the basic questions surrounding man's ability to choose freely—questions about its essence and its existence. What is this liberum arbitrium, which Augustine repeatedly calls "a gift of nature"? How should we understand its activity? How should we understand its origin? Thomas Aquinas deals with liberum arbitrium as a power of the soul in question 83 of Summa theologiae ST I, in question 24 of De veritate, and in chapter 48 of Summa contra gentiles SCG II. These texts are not about the role of grace or the causality of God—though they prepare for the discussion—but simply about the powers of an intellectual nature. How Augustinian is Aquinas's account in these texts?5 End Page 436 I will try to explore the question with reasonable thoroughness in this paper.6 It will surprise no one to hear that my answer to "was Aquinas an Augustinian in his basic treatment of free decision?" is "in a way, no, and in a way, yes." It is both surprising and notable how significantly Aquinas departs from the Augustinian path. The first part of this paper will discuss three major ways in which Aquinas's account of liberum arbitrium breaks openly (by medieval standards) from the type of careful loyalty we see in earlier authors. In the second part of the paper, I will argue that Aquinas's account follows Augustine in distinctive ways: instead of prioritizing Augustine's context and preferred evidence for free decision, Aquinas does more to locate free decision within the quest for happiness which provided the ultimate pattern for Augustine's thought. He is an Augustinian, but of a very different kind. Aquinas's Treatment of Liberum Arbitrium Represents a Significant Break with the Augustinian Tradition It simply was not Thomas's practice to write statements such as: "I am going to treat this topic in a way different from that of Augustine, and I plan to make significant improvements." How, then, can we understand whether, and to what extent, he made a break with Augustine's ideas? Direct comparison of the authors' works is the obvious strategy, but such comparison is complicated by our ignorance of whether Aquinas had actually seen the work in question or was only familiar with quotations from it. So I will employ an additional strategy to reveal Aquinas's breaks with Augustine: I will compare Thomas's work to that of Peter Lombard and Anselm of Canterbury. We know Aquinas had read Peter's work thoroughly, because End Page 437 he wrote a commentary on it, and citations in De veritate reveal that Thomas knew at least the highlights of Anselm's work on free decision. Both Peter and Anselm are faithful to many aspects of Augustine's treatment: they follow him in the way they contextualize the topic, and they are careful to use Augustinian language in defining it. Aquinas does not. He radically shifts the context for the liberum arbitrium discussion and rejects definitions that use Augustine's formulations. He uses a boldly Aristotelian framework to replace a number of elements in Augustine's treatment. Finally, unlike Augustine, Peter, or Anselm, he asks about the...
