  Another version of this strategy begins with a point also made in §6.3, namely that to question a property’s causal relevance is really to question its relevance to some property of the effect. The form of our central causal question, that is, is whether a mental cause qua F causes a behavioral effect qua G. Now when F is an intentional mental property, what G is the object of our question? One  possibility is that it is a behavioral property that, like the mental property, is itself “broad” (see, e.g., Enc 1995).
