Suárez on the Possibility of Causal Overdetermination

This paper studies Francisco Suárez's defence of the possibility of causal overdetermination. I show that, according to Suárez, the main arguments against the possibility of causal overdetermination rely on (i) a flawed conception of causal dependence and (ii) a flawed ontology of action. I argue that his objections to (i) and (ii) amount to a significant challenge to his opponents’ case against the possibility of causal overdetermination.
