The standard conception of action provides us with a conception of agency. According to this view, a being has the capacity to exercise agency just in case it has the capacity to act intentionally, and the exercise of agency consists in the performance of intentional actions and, in many cases, in the performance of unintentional actions (that derive from the performance of intentional actions; see section 2). Call this the standard conception of agency. The standard theory of action provides us with a theory of agency, according to which a being has the capacity to act intentionally just in case it has the right functional organization: just in case the instantiation of certain mental states and events (such as desires, beliefs, and intentions) would cause the right events (such as certain movements) in the right way. According to this standard theory of agency, the exercise of agency consists in the instantiation of the right causal relations between agent-involving states and events.
