According to proponents of the causal exclusion problem, there cannot be a sufficient physical cause and a distinct mental cause of the same piece of behaviour. Increasingly, the causal exclusion problem is circumvented via this compatibilist reasoning: a sufficient physical cause of the behavioural effect necessitates the mental cause of the behavioural effect, so the effect has a sufficient physical cause and a mental cause as well. In this paper, I argue that this compatibilist reply fails to resolve the causal (...) exclusion problem. (shrink)

Nonreductive physicalists endorse the principle of mental causation, according to which some events have mental causes: Sid climbs the hill because he wants to. Nonreductive physicalists also endorse the principle of physical causal completeness, according to which physical events have sufficient physical causes: Sid climbs the hill because a complex neural process in his brain triggered his climbing. Critics typically level the causal exclusion problem against this nonreductive physicalist model, according to which the physical cause is a sufficient cause of (...) the behavioural effect, so the mental cause is excluded from causally influencing Sid’s behaviour. In this paper I demonstrate how numerous nonreductive physicalists have responded to the causal exclusion problem by weakening the principle of physical causal completeness in numerous ways. The result: either numerous nonreductive physicalist solutions fail on account of the fact that they do not satisfy a robustly defined principle of physical causal completeness, or there is an accelerating trend of solving the causal exclusion problem by suitably weakening the principle of physical causal completeness.

The paper replies to Matthew Rellihan’s recent criticism of Thomas Kroedel’s simple argument for downward causation. Rellihan argues that the simple argument equivocates between two notions of realizers of mental properties, namely total realizers and core realizers. According to Rellihan, one premise of the argument is false on each disambiguation. In response, this paper argues that the version of the argument in terms of total realizers is sound after all if we evaluate counterfactual conditionals about the non-occurrence of total realizers (...) correctly.

In this paper, I shall argue that both emergence and downward causation, which are strongly interconnected, presuppose the presence of levels of reality. However, emergence and downward causation pull in opposite directions with respect to my best reconstruction of what levels are. The upshot is that emergence stresses the autonomy among levels while downward causation puts the distinction between levels at risk of a reductio ad absurdum, with the further consequence of blurring the very notion of downward. Therefore, emergence and (...) downward causation are not fit to each other vis-a-vis the concept of level. (shrink)
