  Fodor (1989) apparently agrees that counterfactuals capture a kind of causal relevance, but he argues that LePore and Loewer have settled for too little. On Fodor’s view, mental properties can be relevant to behavior in a stronger sense in which they are sufficient for their effects and in this way “make a difference”. Fodor spells out sufficiency in terms of laws: a property makes a difference if “it’s a property in virtue of the instantiation of which the occurrence of one event is nomologically sufficient for the occurrence of another” (Fodor 1989, p. 65, note omitted).
