After clarifying the dialectical options, I show that he takes action (and thus efficient causation) to be an irreducible or sui generis feature of reality, and moreover that his theological commitments require that he adopt this position. In Chapter 2, I examine action's relationship to the other Aristotelian categories, and in particular whether Suárez thinks action is reducible to any of these categories. Because of the central role of action in ECSs, Chapters 2 and 3 both focus on issues associated with the nature of action. Subsequent chapters aim to address such questions, while paying special attention to the metaphysics of action and causal powers. My discussion of ECSs in the first chapter remains largely neutral on questions about the nature and ontological status of the components of these situations. Among these, action plays the most important role, because Suárez takes it to be the causation or 'causality' (causalitas) of an efficient cause-i.e., that in virtue of which something qualifies as an efficient cause.

I show that he analyzes ECSs in terms of five components: a cause, an effect, an action, a causal power, and a time. According to Suárez, efficient causes produce their effects by acting, where action is to be understood as the exercise of a causal power. In Chapter 1, I explore how Suárez understands efficient-causal situations (ECSs)-i.e., situations (or facts, or states of affairs) that account for the truth of statements of the form 'C efficiently causes E'. The dissertation is divided into four chapters.
