This article discusses an epistemological problem faced by causal explanations of action and a proposed solution. The problem is to justify why one particular reason rather than another is specified as causally efficacious. It is argued that the problem arises independently of one’s preferred conception of singular causal claims, psychological and psychophysical generalizations, and our folk-psychological competence. The proposed fallibilist solution involves the supplementation of the reason given by narratives that contextualize it and provide additional criteria for justifying the causal (...) claim. It is argued that narratives have a distinctive structure that can afford the justification of causal attributions without sui generis powers of narrative explanation having to be invoked. (shrink)
