 Velleman’s way of terminating the regress is to locate a psychological element from which an agent cannot dissociate himself (2015, chs. 5, 7). Because to act is to act for reasons, an agent cannot dissociate himself from a desire to act for reasons – not, that is, without ceasing to be an agent. (Treat the content of that desire as a temporary placeholder; we’ll return to it shortly.) When such a desire contributes in the canonical manner to producing an action (say, by weighing in on the side of other desires that it endorses, and so tipping the decision toward that action), we say that the agent produces the action (in something like the way that when your intestines digest food, we say that you are digesting the food). So, to recapitulate, actions are in the first place owned; an action is owned, in the relevant sense, when it cannot be disowned; the only anchor for an action that an agent cannot disown in turn, without ceasing to be an agent, is (roughly) the desire to act for reasons. So what it takes to be an action is to be (appropriately) produced by such a desire.
