  When a counterfactual is true, there should be something in the world that makes it true. Even granting that, if the cause had not had its mental property, the effect would not have had its behavioral property, in virtue of what is this true? This truthmaker, not the counterfactual itself, is what matters in determining whether a property is causally relevant. And the worry is that once we look at the truthmakers in the mental case, the threat of epiphenomenalism crops up again. Although the effect counterfactually depends on the mental property, this is only because the mental property depends on a physical property doing the real work. The mental property looks like a freeloader (Kim 1998, pp. 70–3, 2007; compare Crane 2008 on a similar issue).
