This paper examines a paradigm case of allegedly successful reductive explanation, viz. the explanation of the fact that water boils at 100°C based on facts about H2O. The case figures prominently in Joseph Levine’s explanatory gap argument against physicalism. The paper studies the way the argument evolved in the writings of Levine, focusing especially on the question how the reductive explanation of boiling water figures in the argument. It will turn out that there are two versions of the explanatory gap (...) argument to be found in Levine’s writings. The earlier version relies heavily on conceptual analysis and construes reductive explanation as a process of deduction. The later version makes do without conceptual analysis and understands reductive explanations as based on theoretic reductions that are justified by explanatory power. Along the way will be shown that the bridge principles — which are being neglected in the explanatory gap literature — play a crucial role in the explanatory gap argument. (shrink)

Can phenomenal consciousness be given a reductive natural explanation? Many people argue not. They claim that there is an.

This paper details an evolving dynamic systems hierarchy and explores its relationship with conceptual, evolutionary, physiological, and behavioural characteristics that include phenomenal experience. In doing this, the paper demonstrates an example of a type-C physicalist's reductive explanation of phenomenal experience that is coherent with stipulated philosophical criteria and theories. By providing a reductive explanation of phenomenal experience, the paper provides insights toward explaining many unique human characteristics. These include, creativity, the origins of language as distinct from animal communication, the evolution (...) of morality, and the dynamics behind bias and prejudice. Furthermore, the reductive explanation provides foundations for artificial consciousness applications. (shrink)

Is conceptual analysis required for reductive explanation? If there is no a priori entailment from microphysical truths to phenomenal truths, does reductive explanation of the phenomenal fail? We say yes (Chalmers 1996; Jackson 1994, 1998). Ned Block and Robert Stalnaker say no (Block and Stalnaker 1999).

among them Joseph Levine, David Chalmers, Frank Jackson and Jaegwon Kim?have claimed that there are conceptual grounds sufficient for ruling out the possibility of a reductive explanation of phenomenal consciousness. Their claim assumes a functional model of reduction (regarded by Kim as an alternative to the traditional Nagelian model) which requires an a priori entailment from the facts in the reduction base to the phenomena to be explained. The aim of this paper is to show that this is an unreasonable (...) requirement?a requirement that no reductive explanation in science should be expected to satisfy. I argue that the functional model is not substantively different from the Nagelian model properly understood, and that the question whether consciousness is reductively explainable?in a sense involving property identifications or in some weaker sense compatible with Nagelian reduction?is a fundamentally empirical question, not one that can be settled on conceptual grounds alone. Introduction Kim's critique of the Nagelian model of reduction The functional model of reduction Is consciousness reducible? Psychophysical reduction: concluding remarks. (shrink)

This paper argues that the form of explanation at issue in the hard problem of consciousness is scientifically irrelevant, despite appearances to the contrary. In particular, it is argued that the.

According to the self-representational theory of consciousness – self- representationalism for short – a mental state is phenomenally conscious when, and only when, it represents itself in the right way. In this paper, I consider how self- representationalism might address the alleged explanatory gap between phenomenal consciousness and physical properties. I open with a presentation of self- representationalism and the case for it (§1). I then present what I take to be the most promising self-representational approach to the explanatory gap (...) (§2). That approach is threatened, however, by an objection to self-representationalism, due to Levine, which I call the just more representation objection (§3). I close with a discussion of how the self-representationalist might approach the objection (§4). (shrink)

This paper is a defence of Terence Horgan’s claim that any genuinely physicalist position must distinguish itself from (what has been traditionally known as) emergentism. I argue that physicalism is necessarily reductive in character -- it must either give a reductive account of apparently non-physical entities, or a reductive explanation of why there are non-physical entities. I argue that many recent ‘nonreductive’ physicalists do not do this, and that because of this they cannot adequately distinguish their view from emergentism. The (...) conclusion is that this is the real challenge posed by Joseph Levine’s ‘explanatory gap’ argument: if physicalists cannot close the explanatory gap in Levine’s preferred way, they must find some other way to do it. Otherwise their view is indistinguishable from emergentism. (shrink)

If one were to provide a reductive explanation of phenomenal experience one would explain why there could be a phenomenal experience that identifies itself as an individual that possesses ‘consciousness’. Although not a requirement of reduction, such an explanation would be consistent with our understanding of evolution and, consequently, explain the physical origins and purpose of phenomenal experience. However, this explanation would not explain why a particular conscious individual identifies itself as itself rather than any other individual - Why is (...) ‘my’ consciousness ‘mine’ (materially, or otherwise, irrespective of experiential detail and content) rather than anyone else? What is consciousness outside of phenomenal experience and phenomenal conceptualization? In this paper, I argue that the indeterminacy of quantum mechanics makes it a suitable candidate for exploring the answers to these questions. (shrink)
