"When we explain action in terms of desires and beliefs we are not putting forward any explanatory theory to account for action. It is true that desires and beliefs explain action; but the explanation is not of any causal hypothetical form. It is not as if the actions of human beings constitute a set of raw data – actions identifiable on their faces as the kinds of actions they are – for which we may seek an explanatory hypothesis. On the contrary, many human actions are not identifiable as actions of a particular kind unless they are already seen and interpreted as proceeding from a particular set of desires and beliefs."
