Given certain anti-Pelagian assumptions he endorses, Aquinas faces an “arbitrariness problem” explaining why God predestines and reprobates the particular individuals he does. One response to the problem that Aquinas offers—biting the bullet and conceding God’s arbitrariness—has a high theoretical cost. Eleonore Stump proposes a less costly alternative solution on Thomas’s behalf, drawing on his notion that our wills may rest in a state of “quiescence.” Her proposal additionally purports to answer the general question why God reprobates anyone at all. I (...) argue that Aquinas’s understanding of the relationship between divine causation and human freedom prevents him from accepting Stump’s proposal as she herself puts it forward; he couldn’t accept it as an answer to the general question. Nevertheless, I claim, granted one controversial but widely accepted assumption—that he isn’t a divine determinist—Aquinas could accept a slightly modified version of her quiescence solution to the arbitrariness problem. Indeed, there is evidence that he did accept some of its key components. (shrink)

Agents are morally responsible for their actions only if they understand what they are doing. This much seems clear, but it is unclear exactly what agents must understand in order to be morally responsible; in other words, the epistemic condition for moral responsibility is difficult to discover. In this paper, I will investigate Aquinas’s discussion of knowledge, voluntariness, and moral responsibility in order to discover his views on this condition. Although he never provides a formal expression of such a condition, (...) I will use his discussions of related issues to construct a three-part epistemic condition for moral responsibility. In the process I will raise and discuss several interpretative difficulties, arguing that while some can be resolved, others, despite recent claims to the contrary, resist resolution. Finally, I will draw out several consequences of his account, noteworthy for a variety of reasons. (shrink)

Little attention has recently been paid to Aquinas's analyses of mixed actions, which constitute a significant sort of border line cases between the voluntary and the involuntary. A textual inconsi...
