agent-causal

For a half - century, I have been developing a view of free will that is incompatible with determinism and, in the process, attempting to answer the Intelligibility Question about such a free will: Can one make sense of an incompatibilist or libertarian free will without reducing it to mere chance, or mystery, and can such a free will be reconciled with modern views of the cosmos and human beings? In this paper, I discuss recent refinements to my earlier writings on such a view, refinements developed in recent years in response to the large critical literature on my views in the past several decades. My view has usually been designated an event-causal (EC) view of libertarian free will and distinguished from non-causal (NC) and agent-causal (AC) libertarian views. But I was never happy with this designation of my view as “event-causal” and did not use it myself in earlier writings. In this paper, I explain why I now reject it altogether. I have come to believe that to avoid numerous misunderstandings in current debates about free will, we must distinguish four different kinds of libertarian theories, not merely three: in addition to non-causal (NC), agent-causal (AC), and event-causal (EC) theories, we need to add a fourth kind, which might be called an agent-causal/event-causal (AC/EC) theory. My view has always been of this fourth kind. It represents what I call in the title of this paper the “fourth way forward” for making sense of an incompatibilist free will.

According to event-causal modest libertarian accounts of free action, the sort of control an agent requires to perform free actions consists in the action’s being nondeviantly and indeterministically caused by apt reasons of the agent. It has been argued that these modest views succumb to a problem of luck because they imply that, given exactly the same past up to the time of action, and the same laws of nature, at this time the agent could have performed a different action, or no action at all. Hence, it appears that whatever the agent does at this time as a result of indeterministic deliberation is a matter of freedom- or responsibility-undermining luck. In this paper, I argue that neither Robert Kane’s variant of modest libertarianism, which combines a form of non-traditional agent causation with indeterministic event causation, nor John Lemos’ weightings variant, in which agents perform intentional acts of assigning weights to their reasons, circumvents the luck objection.
