The question of what we are doing when we give an explanation in terms of the agent's reasons for his behaviour is both familiar and complicated. The question I shall raise here, however, is somewhat more limited. It is that of what is involved in making use of such explanations once we have some cursory acquaintance with their structure. In particular, I wish to draw attention to some relations between explanations in terms of intended goals and relations in terms of the agent's reasons for an act.
