Suárez and the Empirical Foundation of Efficient Causality

For Suárez, the general notion of efficient causality and the reality of it are known not through an abstraction from supposed “primitive” experiences of connection between causes and effects but indirectly, through a reasoning that begins with what is directly observed and ends with the evidence that it is really in the things themselves. In this paper, I intend to show the plausibility of this interpretation in the following way: first, I will quickly present a passage in which Suárez claims that efficient causality is evident; second, I will show in which sense the principle “nothing can transfer itself from nonbeing to being” has an empirical basis; and, third, I will show how the reality of efficient causation among things of the empirical world can be demonstrated from the experience of a rational order in them.
