A defense of the causal efficacy of dispositions

A defense of the causal efficacy of dispositions" (2004). Faculty Publications-Department of Philosophy. Paper 32. Disposition terms, such as 'cowardice,' 'fragility' and 'reactivity,' often appear in explanations. Sometimes we explain why a man ran away by saying that he was cowardly, or we explain why something broke by saying it was fragile. Scientific explanations of certain phenomena feature dispositional properties like instability, reactivity, and conductivity. And these look like causal explanations-they seem to provide information about the causal history of various events. have suggested reasons for thinking that dispositions are causally inert. I call this the "Inert Dispositions View." According to this view, the glass's fragility was not responsible for its breaking; the man's cowardice was causally impotent as he fled. The Inert Dispositions View would call many of the explanations we give into question. By employing a disposition in an explanation, we might have thought we were giving a causal explanation of the event. Perhaps we took ourselves to be explaining an effect with some feature of its cause that was responsible for the effect. However, if dispositions are causally inert, we are explaining the event in some other way, or not really explaining it at all. The Inert Dispositions View suggests that something is amiss with many scientific explanations. If properties like conductivity and volatility are causally inert, it is not clear how appealing to them provides us with information about why certain phenomena occur. This is especially problematic if one thinks, as some do, that the fundamental properties that scientists attribute to the ultimate
