The causal theory of action, which has been the standard theory of action, presupposes that reasons for action are an agentʼs mental attitudes (e.g. beliefs and desires) and claims that they are the cause of the action. However, in this paper I argue that reasons for action are not the agentʼs mental attitudes but their object (e.g. facts, states of affairs, or propositions), inspired by the idea that reasons must be capable of justifying the action as well as explaining it, and that what has this normative force is not mental items, but something objective. I also solve a problem that derives from cases in which the agent believes things falsely.
