This paper features Derk Pereboom’s replies to commentaries by Victor Tadros and Saul Smilansky on his non-retributive, incapacitation-focused proposal for treatment of dangerous criminals; by Michael McKenna on his manipulation argument against compatibilism about basic desert and causal determination; and by Alfred R. Mele on his disappearing agent argument against event-causal libertarianism.

Moral responsibility theorists divide over whether facts about holding someone morally responsible are dependent on facts about being morally responsible, or whether the dependence relation runs in the other direction. A novel answer, proposed by Michael McKenna, is that neither side depends on the other. Instead, they are interdependent. Call this the ‘interdependence thesis’. A worry is that the interdependence thesis violates formal principles of metaphysical dependence in terms of ground. This paper analyses and defends the interdependence thesis, interacting with (...) recent work in the metaphysics of grounding. I vindicate the interdependence thesis from the charge that it violates the formal principles of metaphysical grounding. I then pull from recent work in communication theory and apply it to McKenna's ‘conversational theory of moral responsibility’, in order to respond to two new objections. One upshot is that I advance the conversational theory of moral responsibility. (shrink)

In recent decades, participants in the debate about whether we are free and responsible agents have tended with increasing frequency to begin their papers or books by fixing the terms “free” and “responsible” in clear ways to avoid misunderstanding. This is an admirable development, and while some misunderstandings have certainly been avoided, and positions better illuminated as a result, new and interesting questions also arise. Two ways of fixing these terms and identifying the underlying concepts have emerged as especially influential, (...) one that takes the freedom required for responsibility to be understood in terms of accountability and the other in terms of desert. In this paper, I start by asking: are theorists talking about the same things, or are they really participating in two different debates? Are desert and accountability mutually entailing? I tentatively conclude that they are in fact mutually entailing. Coming to this conclusion requires making finer distinctions among various more specific and competing accounts of both accountability and desert. Ultimately, I argue, that there is good reason to accept that accountability and desert have the same satisfaction conditions. (shrink)
