There is, as we have seen, good reason to distinguish between different kinds of agency. The standard theory offers an account of what is, arguably, the most central kind of agency: intentional agency (and the kind of unintentional agency that derives from it; see section 2). This can be distinguished from higher or more refined kinds of agency, such as self-controlled, autonomous, and free agency, and it can be distinguished from more basic kinds of agency that do not require the ascription of representational mental states. Apart from that, there are several candidates for further kinds of agency. They include mental agency, shared agency, collective agency, relational agency, and artificial agency. In each case, we can ask whether the agency in question can be explained in terms of the standard conception and theory, or whether it is indeed a different kind of agency. The main focus in this section will be on mental agency, and we will address the other candidates only very briefly.
