I recently argued that reductive physicalist versions of libertarian free will face a physical indeterminism luck objection. John Lemos claims that one potential advocate of reductive physicalist libertarianism, Robert Kane, avoids this physical indeterminism luck objection. I here show how the problem remains.

Libertarian free will is, roughly, the view that agents cause actions to occur or not occur: Maddy’s decision to get a beer causes her to get up off her comfortable couch to get a beer, though she almost chose not to get up. Libertarian free will notoriously faces the luck objection, according to which agential states do not determine whether an action occurs or not, so it is beyond the control of the agent, hence lucky, whether an action occurs or (...) not: Maddy’s reasons for getting beer in equipoise with her reasons to remain in her comfortable seat do not determine that she will get up or stay seated, so it seems beyond her control, hence lucky, that she gets up. In this paper I consider a sub-set of the luck objection called the Physical Indeterminism Luck Objection, according to which indeterministic physical processes cause actions to occur or not, and agent’s lack control over these indeterministic physical processes, so agent’s lack control over, hence it is lucky, whether action occurs or not. After motivating the physical indeterminism luck objection, I consider responses from three recent event-causal libertarian models, and conclude that they fail to overcome the problem, though one promising avenue is opened up.

Nonreductive physicalism states that actions have sufficient physical causes and distinct mental causes. Nonreductive physicalism has recently faced the exclusion problem, according to which the single sufficient physical cause excludes the mental causes from causal efficacy. Autonomists respond by stating that while mental-to-physical causation fails, mental-to-mental causation persists. Several recent philosophers establish this autonomy result via similar models of causation :1031–1049, 2016; Zhong, J Philos 111:341–360, 2014). In this paper I argue that both of these autonomist models fail on account (...) of the problem of Edwards’s Dictum. However, I appeal to foundational principles of action theory to resuscitate mental-to-mental causation in a manner that is consistent with the models of causation endorsed by these autonomists.

Libertarian free will is, roughly, the view that the same agential states can cause different possible actions. Nonreductive physicalism is, roughly, the view that mental states cause actions to occur, while these actions also have sufficient physical causes. Though libertarian free will and nonreductive physicalism have overlapping subject matter, and while libertarian free will is currently trending at the same time as nonreductive physicalism is a dominant metaphysical posture, there are few sustained expositions of a nonreductive physicalist model of libertarian (...) free will – indeed some tell against such an admixture. This paper concocts such a blend by articulating and defending, with some caveats, a nonreductive physicalist model of libertarian free will. (shrink)

There is a difference between having reasons for believing and believing for reasons. This difference is often fleshed out via an epistemic basing relation, where an epistemic basing relation obtains between beliefs and the actual reasons for which those beliefs are held. The precise nature of the basing relation is subject to much controversy, and one such underdeveloped issue is whether beliefs can be based on brain processing. In this paper I answer in the negative, providing reasons that the basing (...) relation must be a specific psychological level relation between mental states, rather than being a brain process.

Jaegwon Kim once refrained from excluding distinct mental causes of effects that depend upon the sufficient physical cause of the effect. At that time, Kim also refrained from excluding distinct mental explanations of effects that depend upon complete physical explanations of the effect. More recently, he has excluded distinct mental causes of effects that depend upon the sufficient cause of the effect, since the physical cause is individually sufficient for the effect. But there has been, to this point, no parallel (...) shift in the explanatory realm, such that distinct mental explanations of effects that depend upon complete physical explanations of the effect are excluded since the physical explanation is objectively complete. In this paper I consider, defend, and apply this update to the principle of explanatory exclusion—an update, which, in the final analysis, demonstrates a significant advantage that non-reductive physicalism has over reductive physicalism.

The argument from reason states that if naturalism is true, then our beliefs are caused by physical processes rather than being causally based in their reasons, so our beliefs are not knowledge—including the belief in naturalism itself. Recent critics of the argument from reason provide dual process replies to the argument from reason—our beliefs can have both a naturalistic cause/ explanation and be caused/explained by its reasons, thereby showing that naturalism can accommodate knowledge. In this paper I consider three dual (...) process replies and conclude that none of them are successful. (shrink)
