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.

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)

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)

Nonreductive physicalists endorse autonomous mental causation, the view that mental causes, as distinct from physical causes, bring about mental and physical effects. The causal exclusion problem has recently pressured nonreductive physicalists to replace autonomous mental causation with reduced mental causation, the view that mental causes, as physical causes, bring about mental and physical effects. Reduced mental causation, in turn, faces the problem of mental quausation, according to which reduced mental causation only delivers mental‐as‐physical causation, not the requisite mental‐as‐mental causation. Proponents (...) of reduced mental causation have responded by emphasizing the success of reduction in delivering mental causation, while questioning the metaphysical legitimacy of mental quausation (Tiehen, 2019; Gibb, 2017; Robb, 2017; 2013).1 In this paper, I argue that the requirement for mental quausation not only withstands these objections, but that mental quausation is an inevitable problematic for any version of reduced mental causation.

In recent literature on the metaphysics of consciousness, and in particular on the prospects of physicalism, there are two interesting strands of discussion. One strand concerns the so-called ‘thesis of revelation’, the claim that the essences of phenomenal properties are revealed in experience. The other strand concerns the intuition of dualism, the intuition that consciousness is nonphysical. With a particular focus on the former, this paper advances two main arguments. First, it argues that the thesis of revelation is intuitive; it (...) is part of our ordinary, implicit conception of experience. Second, it brings the two strands of discussion together and puts forward a rational explanation of the intuition of dualism in terms of the intuitiveness of the thesis of revelation. (shrink)

‘Space does not exist fundamentally: it emerges from a more fundamental non-spatial structure.’ This intriguing claim appears in various research programs in contemporary physics. Philosophers of physics tend to believe that this claim entails either that spacetime does not exist, or that it is derivatively real. In this article, I introduce and defend a third metaphysical interpretation of the claim: reductionism about space. I argue that, as a result, there is no need to subscribe to fundamentality, layers of reality and (...) emergence in order to analyse the constitution of space by non-spatial entities. It follows that space constitution, if borne out, does not provide empirical evidence in favour of a stratified, Aristotelian in spirit, metaphysics. The view will be described in relation to two particular research programs in contemporary physics: wave function realism and loop quantum gravity. (shrink)

David. J. Chalmers examines eleven possible solutions to the meta-problem of consciousness, ‘the problem of explaining why we think that there is a problem of consciousness.’ The present paper argues that Chalmers overlooks an explanation that he has otherwise taken seriously, and which a number of philosophers, physicists, and computer scientists have taken seriously as well: the hypothesis that we are living in a computer simulation. This paper argues that a particular version of the simulation hypothesis is at least as (...) good of a solution to the meta-problem of consciousness as many explanations Chalmers considers, and may even be a better one—as it may be the best solution to a much broader meta-philosophical problem: the ‘meta-problem of everything’, the problem of explaining why our world has the quantum-mechanical, relativistic, and philosophical features it does.

In this dissertation, I develop and defend a model of causation that allows for dualist mental causation in worlds where the physical domain is physically complete. In Part I, I present the dualist ontology that will be assumed throughout the thesis and identify two challenges for models of mental causation within such an ontology: the exclusion worry and the common cause worry. I also argue that a proper response to these challenges requires a thoroughly lightweight account of causation, i.e. an (...) account that allows for causes to be metaphysically distinct from the phenomena that produce or physically necessitate their effects. In Part II, I critically evaluate contemporary responses to these challenges from the philosophical literature. In particular, I discuss List and Stoljar’s criticism of exclusion worries, Kroedel’s alternative dualist ontology, concerns about the notion of causal sufficiency, and Lowe’s models of dualist mental causation. I argue that none of these proposals provide independent motivation for a thoroughly lightweight account of causation and therefore leave room for improvement. In the first four chapters of Part III, I develop a thoroughly lightweight model of causation, which builds on interventionist approaches to causation. First, I explain how so-called ‘holding fixed’-requirements in standard interventionist accounts stand in the way of dualist mental causation. I then argue that interventionist accounts should impose a robustness condition on causal correlations and that, with this condition in place, the ‘holding fixed’-requirements can be weakened such that they do allow for dualist mental causation. I dub the interventionist model with such weakened ‘holding fixed’-requirements ‘insensitive interventionism’, argue that it can counter the exclusion worry as well as the common cause worry, and explain under which circumstances it would predict there to be dualist mental causation. Importantly, these circumstances might, for all we know, hold in the actual world. In the final three chapters of Part III, I defend insensitive interventionism against some objections. I consider the objection that causation must be productive, the objection that causes must physically necessitate their effects, and the objection that insensitive interventionism is too permissive. I respond by drawing from the literature on causation by absences and on the relation between causation and fundamental physics. Overall, insensitive interventionism performs as well as standard interventionist accounts. I conclude that insensitive interventionism is a credible model of causation. (shrink)
