This paper defends the view that philosophical propositions are merely relatively true, i.e. true relative to a doxastic perspective defined at least in part by a non-inferential belief-acquiring method. Here is the strategy: first, the primary way that contemporary philosophers defend their views is through the use of rational intuition, and this method delivers non-inferential, basic beliefs which are then systematized and brought into reflective equilibrium. Second, Christian theologians use exactly the same methodology, only replacing intuition with revelation. Third, intuition (...) and revelation yield frequently inconsistent output beliefs. Fourth, there is no defensible reason to prefer the dictates of intuition to those of Christian revelation. Fifth, the resulting dilemma means that there are true philosophical propositions, but we can't know them (scepticism), or there are no philosophical propositions and the naturalists are right (nihilism), or relativism is true. I suggest that relativism is the most palatable of these alternatives. (shrink)

In this paper I examine Jaegwon Kim’s view that emergent properties are irreducible to the base properties on which they supervene. Kim’s view assumes a model of ‘functional reduction’ which he claims to be substantially different from the traditional Nagelian model. I dispute this claim and argue that the two models are only superficially different, and that on either model, properly understood, it is possible to draw a distinction between a property’s being reductively identifiable with its base property and a (...) property’s being reductively explainable in terms of it. I propose that we should take as the distinguishing feature of emergent properties that they be truly novel properties, i.e., ontologically distinct from the ‘base’ properties which they supervene on. This only requires that emergent properties cannot be reductively identified with their base properties, not that they cannot be reductively explained in terms of them. On this conception the set of emergent properties may well include mental properties as conceived by nonreductive physicalists. (shrink)

As tends to be the way with philosophical positions, there are at least as many two-dimensionalisms as there are two-dimensionalists. But painting with a broad brush, there are core epistemological and metaphysical commitments which underlie the two-dimensionalist project, commitments for which I have no sympathies. A sketch of three signi?cant points of disagreement.

ABSTRCT: In this commentary, I criticize Metzinger's interdisciplinary approach to fixing the explanandum of a theory of consciousness and I offer a commonsense alternative in its place. I then re-evaluate Metzinger's multi-faceted working concept of consciousness, and argue for a shift away from the notion of "global availability" and towards the notio ns of "perspectivalness" and "transparency." This serves to highlight the role of Metzinger's "phenomenal model of the intentionality relation" (PMIR) in explaining consciousness, and it helps to locate Metzinger's (...) theory in relation to other naturalistic theories of.

In _The Significance of Consciousness_ , Charles Siewert proposes a novel understanding of consciousness by arguing against higher-order views of consciousness and rejecting the traditional taxonomy of the mental into qualitative and intentional aspects. I discuss two puzzles that arise from these changes: first, how to account for first-person knowledge of our conscious states while denying that these are typically accompanied by higher-order states directed towards them; second, how to understand his claim that phenomenal features are intentional features without either (...) risking consciousness neglect or retreating to a more traditional understanding of the relation between qualitative and intentional character.

This paper uses the explanation of blindsight generated by a two-systems theory of vision in order to set Siewert a dilemma. Either his blindsight examples are modelled on actual blindsight, in which case certain reductive theories of phenomenal consciousness will have no difficulty in accommodating them. Or they are intended to be purely imaginary, in which case they will have no force against a reductive naturalist.

This thesis develops an account of the nature of wakeful consciousness. Its principal suggestion is that wakeful consciousness is a biological phenomenon and should thus be placed in the context appropriate to biological phenomena. That context is the characterizing form of life of organisms. Once wakeful consciousness is assigned its place in this context, it emerges that wakeful consciousness is a teleological phenomenon, one that is to be understood as having the proper function of putting its bearer in touch with (...) the world. What emerges from reflection on the metaphysics of organisms is an account of wakeful consciousness that is teleological in character but which does not fall foul of the strictures of physicalism and casts new light on recent philosophical debates about consciousness.

The paper is concerned with the metaphysics of emotion. It defends the claim that all emotional states, whether dormant or active, are dispositional, arguing against the prevailing view that dispositional emotional states are dispositions to go into actual emotional states. A clear distinction may be made between first-order and second-order emotional dispositions, where second-order emotional dispositions are dispositions of emotional sensitivity and first-order emotional dispositions are the emotional states themselves. Active emotional states are treated as dispositional emotional states in the (...) process of being manifested, not as different states altogether. Describing active states as occurrent states is misleading as it suggests an exclusive distinction between active/occurrent and dispositional, which is what is being questioned. The idea that dispositional states have no subjectivity is challenged, as is the argument that being flooded with a feeling as a result of an encounter with a frightening or aggravating situation cannot be the manifestation of a disposition.

The theory of concepts advanced in the dissertation aims at accounting for a) how a concept makes successful practice possible, and b) how a scientific concept can be subject to rational change in the course of history. Traditional accounts in the philosophy of science have usually studied concepts in terms only of their reference; their concern is to establish a stability of reference in order to address the incommensurability problem. My discussion, in contrast, suggests that each scientific concept consists of (...) three components of content: 1) reference, 2) inferential role, and 3) the epistemic goal pursued with the concept's use. I argue that in the course of history a concept can change in any of these three components, and that change in one component—including change of reference—can be accounted for as being rational relative to other components, in particular a concept's epistemic goal.This semantic framework is applied to two cases from the history of biology: the homology concept as used in 19th and 20th century biology, and the gene concept as used in different parts of the 20th century. The homology case study argues that the advent of Darwinian evolutionary theory, despite introducing a new definition of homology, did not bring about a new homology concept (distinct from the pre-Darwinian concept) in the 19th century. Nowadays, however, distinct homology concepts are used in systematics/evolutionary biology, in evolutionary developmental biology, and in molecular biology. The emergence of these different homology concepts is explained as occurring in a rational fashion. The gene case study argues that conceptual progress occurred with the transition from the classical to the molecular gene concept, despite a change in reference. In the last two decades, change occurred internal to the molecular gene concept, so that nowadays this concept's usage and reference varies from context to context. I argue that this situation emerged rationally and that the current variation in usage and reference is conducive to biological practice.The dissertation uses ideas and methodological tools from the philosophy of mind and language, the philosophy of science, the history of science, and the psychology of concepts.

Abstract:This essay aims to bring two important lines of inquiry and criticism together. It first lays out an institutionally enriched account of what a just world economic order will look like. That account prescribes, via the requisites to that mechanism which most directly instantiates the account, “three realms of equal treatment and market completion”—the global products, services, and labor markets; the global investment/financial markets; and the global preparticipation opportunity allocation. The essay then suggests how, with minimal if any departure from (...) familiar canons of traditional international legal mandate interpretation, each of the Bretton Woods institutions—particularly the GATT/WTO and the IMF—can be viewed at least in part as charged with the task of fostering equal treatment and ultimate market completion within one of those three realms. The piece then argues that one of the institutions in particular—the World Bank—has, for reasons of at best negligent and at worst willful injustice on the part of influential state actors in the world community, fallen farthest short in pursuit of what should be viewed as its proper mandate. The article accordingly concludes that a fuller empowerment of the Bank to effect its ideal mission will press the Bretton Woods system more nearly into ethical balance, and with it the world into justice; and that full empowerment of the GATT/WTO and IMF should be partly conditioned upon the fuller empowerment of the Bank.

David Lewis argues for Ramseyan humility, the thesis that we can’t identify the fundamental properties that occupy the nomological roles at our world. Lewis, however, remarks that there is a potential exception to this, which involves assuming two views concerning qualia panphenomenalism : all instantiated fundamental properties are qualia and the identification thesis : we can know the identities of our qualia simply by being acquainted with them. This paper aims to provide an exposition, as well as an assessment, of (...) this response to the humility thesis. (shrink)

In his bookThe Conscious MindDavid Chalmers introduced a now-familiar distinction between the hard problem and the easy problems of consciousness. The easy problems are those concerned with the question of how the mind can process information, react to environmental stimuli, and exhibit such capacities as discrimination, categorization, and introspection. All of these abilities are impressive, but they are, according to Chalmers, not metaphysically baffling, since they can all be tackled by means of the standard repertoire of cognitive science and explained (...) in terms of computational or neural mechanisms. This task might still be difficult, but it is within reach. In contrast, the hard problem — also known astheproblem of consciousness — is the problem of explaining why mental states have phenomenal or experiential qualities. Why is it like something to ‘taste coffee,’ to ‘touch an ice cube,’ to ‘look at a sunset,’ etc.? Why does it feel the way it does? Why does it feel like anything at all? (shrink)

This paper considers the extent to which the notion of truthmaking can play a substantive role in defining physicalism. While a truthmaking-based approach to physicalism is prima facie attractive, there is some reason to doubt that truthmaking can do much work when it comes to understanding physicalism, and perhaps austere metaphysical frameworks in general. First, despite promising to dispense with higher-level properties and states, truthmaking appears to make little progress on issues concerning higher-level items and how they are related to (...) how things are physically. Second, it seems that truthmaking-based approaches to physicalism will have a difficult time addressing the status of truthmaking itself without, in effect, appealing to the resources of alternative ways of conceptualizing physicalism.

This article explores two consequences of intentionalism. My first line of argument focuses on the impact of intentionalism on the 'hard problem' of phenomenal character. If intentionalism is true, the phenomenal supervenes on the intentional. Furthermore, if physicalism about the intentional is also true, the intentional supervenes on the physical. Therefore, if intentionalism and physicalism are both true, then, by transitivity of supervenience, physicalism about the phenomenal is true. I argue that this transitivity argument is not persuasive, because on any (...) interpretation of its central terms, at least one of its premises is as controversial as its conclusion already is. My second line of argument is about the consequences of intentionalism for the error theory of color perception. I suggest that if intentionalism is true, projectivism must be true also, because under this condition there is no single concept of color that can be used for the qualification of objects as well as for the characterization of experiences.

I utilize recent work in analytic epistemology on the notion of essentially indexical knowledge, as well as Marion’s notion of saturated phenomenality, to ground the psychological model of the Trinity. I argue that classical theism implies that God is essentially omniscient. This omniscience entails complete self-knowledge on God’s part. There are, however, truths about God’s consciousness that are reducible neither to concepts nor to 1st person experience. These are the truths about how God’s presence is perceived from a 2nd person (...) perspective. In order for God to know such truths about himself, he would have to experience himself as both an ‘I’ and a ‘You.’ Thus, God must exist as a being with multiple subjective centers of consciousness.

From the time of Descartes to about the 1960s, a certain epistemological idea dominated the philosophy of mind, namely the idea that theses about the relation between mind and body are, if true, a priori truths. Much of recent philosophy of mind is devoted to the question whether that idea is right. My research is largely an attempt to argue that some recent defenses of it are unsuccessful. ;For example, Physicalism is the metaphysical thesis that every actual psychological event, property, (...) or process is necessitated by some actual physical event, property, or process. Many philosophers believe that Physicalism is true. Until about the 1960s, those who believed it true typically believed that statements relating mind and body were a priori truths. Let us call this thesis A Priori Physicalism. Many philosophers nowadays believe, instead, that statements relating mind and body are only a posteriori truths. Let us call this thesis A Posteriori Physicalism. A number of philosophers have argued in recent years that A Posteriori Physicalism is unacceptable; on their view, Physicalists had better be A Priori Physicalists. My thesis examines the question whether that view is correct. ;I begin with a discussion of two influential arguments for the conclusion that Physicalists must be A Priori Physicalists. Chapter 1 addresses itself to an argument for the conclusion that if physicalism is true, every referring psychological expression is coreferential a priori with some referring physical expression. This argument is commonly called the Property Dualism Argument against Physicalism. I argue that the Property Dualism Argument rests on an ambiguous premise: on one reading it begs the question against A Posteriori Physicalism, on the other reading the conclusion of the Property Dualism Argument does not follow. ;Chapter 2 addresses itself to an argument of Frank Jackson's for the conclusion that Physicalists must have an a priori story to tell about how the physical nature of the actual world makes true the psychological nature of the actual world. I distinguish two ways in which this claim might be understood, and I argue that on neither way of understanding it does Jackson have a compelling argument for A Priori Physicalism. ;Finally, in Chapter 3 I turn to a more general discussion of the relation between conceivability and possibility, and its bearing on the dispute between A Priori and A Posteriori Physicalists. I focus in particular on a recent argument of David Chalmers' from the conceivability of so-called zombies to the conclusion that A Posteriori Physicalism is false. I argue that this argument fails to provide compelling reasons for rejecting A Posteriori Physicalism. I argue, first, that it misconstrues the relation between conceivability and possibility, and second, that it fails to establish that zombies are conceivable in the relevant sense. (shrink)

This paper aims to show that there is a lot of philosophy in the philosophy of chemistry—not only in the problems and questions specific to chemistry, which this science brings up in philosophical discussions, but also in the topics of wider interest like reductionism and emergence, for which chemistry proves to be an ideal case study. The fact that chemical entities and properties are amenable to a quantitative understanding, to measurement and experiment to a greater extent than those in psychology (...) or biology, makes chemistry an ideal case study for those interested in reductionism and emergence.

This paper will articulate and defend a novel theory of epistemic justification; I characterize my view as the thesis that justification is potential knowledge . My project is an instance of the ‘knowledge-first’ programme, championed especially by Timothy Williamson. So I begin with a brief recapitulation of that programme.

In Zhong (Philos Phenomenol Res 83:129–147, 2011; Analysis 72:75–85, 2012), I argued that, contrary to what many people might expect, the counterfactual theory of causation will generate (rather than solve) the exclusion problem. Recently some philosophers raise an incisive objection to this argument. They contend that my argument fails as it equivocates between different notions of a physical realizer (see Christensen and Kallestrup in Analysis 72:513–517, 2012). However, I find that their criticism doesn’t threaten the central idea of my view. (...) In this paper, I make two separate responses that appeal to two unequivocal notions of physical realizers, respectively. I aim to show that a modified argument that uses either notion would work.

Though physicalism remains the most popular position in the metaphysics of mind today, there is still considerable debate over how to retain a plausible account of mental concepts consistently with a physicalistic world view. Philip Goff (Australasian Journal of Philosophy 89(2), 191–209, 2011) has recently argued that physicalism cannot give a plausible account of our phenomenal concepts, and that as such, physicalism should be rejected. In this paper I hope to do three things, firstly I shall use some considerations from (...) ontology to rebut Goff’s argument and consider some objections and replies. Secondly, I shall outline a version of a posteriori physicalism about phenomenal consciousness which draws on this particular ontology. Thirdly, I shall give support to this version of physicalism by arguing that it marries well with prominent theories in cognitive science, and has important advantages over other versions of a posteriori physicalism.

Two of the most fundamental questions about language are these: what are languages?; and, what is it to know a given language? Many philosophers who have reflected on these questions have presented answers that attribute a central role to conventions. In one of its boldest forms such a view runs as follows. Languages are either social entities constituted by networks of social conventions or abstract objects where when a particular community speaks a given language they do so in virtue of (...) the conventions operative within that community. Consequently, for an individual to know a given language is for them to be party to the relevant conventions. Call this view conventionalism. In this article my aim is to evaluate conventionalism. I will argue that although there are linguistic conventions and that they do play an important role in language development and communication conventionalism should be rejected in favour of a more psychologistically orientated position.

Truthmaker theorists hold that propositions about higher-level entities (e.g. the proposition that there is a heap of sand) are often made true by lower-level entities (e.g. by facts about the configuration of fundamental particles). This generates a problem: what should we say about these higher-level entities? On the one hand, they must exist (since there are true propositions about them), on the other hand, it seems that they are completely superfluous and should be banished for reasons of ontological parsimony. Some (...) truthmaker theorists—most prominently David Armstrong—have tried to solve this puzzle by arguing that these entities are ‘an ontological free lunch’, i.e. real existents that are still ‘no addition of being’. This answer is prima facie attractive, but I argue in this paper that the standard approaches to truthmaking—modal theories and grounding theories—are unable to vindicate the doctrine of the ontological free lunch, and thus fail to solve the problem of higher-level entities. Fortunately, there is a non-standard account of truthmaking available, the reductive explanation account, which succeeds where the standard approaches fail. (shrink)

In addition to conceiving of such imaginary scenarios as those involving philosophical zombies, we may conceive of such things being conceived. Call these higher order conceptions ‘meta-conceptions’. Sorensen (2006) holds that one can entertain a meta-conception without thereby conceiving of the embedded lower-order conception. So it seems that I can meta-conceive possibilities which I cannot conceive. If this is correct, then meta-conceptions provide a counter-example to the claim that possibility entails conceivability. Moreover, some of Sorensen’s discussion suggests the following argument: (...) if the conceivability of some proposition entails its possibility, then the meta-conceivability of some proposition entails its possibility; but we can meta-conceive impossibilities; so conceivability doesn’t entail possibility. In this paper, I’ll argue that one cannot entertain a meta-conception without thereby conceiving of the embedded lower-order conception. And so we can neither meta-conceive impossibilities nor meta-conceive possibilities of which we cannot thereby conceive. (shrink)

Abstract. Contrary to proposals that seek a harmonious integration of “science and religion” or “science and spirituality,” I argue that contemporary scientific and philosophical work at the mind-brain interface gives us reason to be skeptical of many of the claims found within religious spiritualities. Religious spiritualities typically presume commitment to strong versions of metaphysical dualism, while contemporary mind science gives us every reason to think that the mind is the brain. If materialism is true, what becomes of spirituality? Materialism or (...) naturalism is widely understood to be an anti-religious position with corrosive effects on morality. I correct this impression, arguing that materialism offers a compelling account of moral objectivity and is fully compatible with an appreciation for many aspects of religion. I further suggest that nothing precludes dialogue and conversation between naturalists and religious believers. (shrink)

Twentieth century philosophy and psychology have been peculiarly averse to mental images. Throughout nearly two and a half millennia of philosophical wrangling, from Aristotle to Hume to Bergson, images (perceptual and quasi-perceptual experiences), sometimes under the alias of "ideas", were almost universally considered to be both the prime contents of consciousness, and the vehicles of cognition. The founding fathers of experimental psychology saw no reason to dissent from this view, it was commonsensical, and true to the lived experience of conscious (...) thinking. However, early in this century, just about when the behaviorist revolution in psychology was loudly declaring the scientific illegitimacy of any attempt to study consciousness, and the concomitant non-existence of imagery (Watson, 1913; see Thomas, 1989), philosophy was undergoing its "linguistic turn", a turn to seeing philosophy as essentially about language rather than the world, even the 'inner' world. For decades, the very concept of the mental image was suspect, and it was certainly banished from playing any major role in theories of mind and of thinking. Ralph Ellis' Questioning Consciousness, together with the recent speculations of certain influential neuroscientists (Edelman, 1992; Damasio, 1994), may be signaling the end this unusual era.

Over the past few decades, as philosophers of mind have begun to rethink the sharp divide that was traditionally drawn between the phenomenal character of an experience (what it’s like to have that experience) and its intentional content (what it represents), representationalist theories of consciousness have become increasingly popular. On this view, phenomenal character is reduced to intentional content. This article explores a key motivation for this theory, namely, considerations of experiential transparency. Experience is said to be transparent in that (...) we ‘look right through it’ to the objects of that experience, and this is supposed to support the representationalist claim that there are no intrinsic aspects of our experience.

(1999). Information self‐organization and consciousness—towards a holoinformational theory of consciousness. World Futures: Vol. 53, No. 4, pp. 309-327.

The question about the potential for consciousness of artificial systems has often been addressed using thought experiments, which are often problematic in the philosophy of mind. A more promising approach is to use real experiments to gather data about the correlates of consciousness in humans, and develop this data into theories that make predictions about human and artificial consciousness. A key issue with an experimental approach is that consciousness can only be measured using behavior, which places fundamental limits on our (...) ability to identify the correlates of consciousness. This paper formalizes these limits as a distinction between type I and type II potential correlates of consciousness (PCCs). Since it is not possible to decide empirically whether type I PCCs are necessary for consciousness, it is indeterminable whether a machine that lacks neurons or hemoglobin, for example, is potentially conscious. A number of responses have been put forward to this problem, including suspension of judgment, liberal and conservative attribution of the potential for consciousness and a psychometric scale that models our judgment about the relationship between type I PCCs and consciousness.

Our chronically impoverished explanatory capacity in respect of P-consciousness is highly suggestive of a problem with science itself, rather than its lack of acquisition of some particular knowledge. The hidden assumption built into science is that science itself is a completed human behaviour. Removal of this assumption is achieved through a simple revision to our science model which is constructed, outlined and named ‘dual aspect science’ (DAS). It is constructed with reference to existing science being ‘single aspect science’. DAS is (...) consistent with and predictive of the very explanatory poverty that generated it and is simultaneously a seamless upgrade; no existing law of nature is altered or lost. The framework is completely empirically self-consistent and is validated empirically. DAS eliminates the behavioural inconsistencies currently inhabiting a world in which single aspect science has been inherited rather than chosen and in which its presuppositions are implemented through habit rather than by scientific examination of options by the scientists actually carrying out science. The proposed DAS framework provides a working vantage point from which an explanation of P-consciousness becomes expected and meaningful. The framework requires that we rediscover what we scientists do and then discover something new about ourselves: that how we have been doing science is not the entire story. Dual aspect science shows us what we have not been doing. (shrink)

This paper focuses on the emergent neo-Jamesian perspective concerning the phenomenology of art and aesthetic experience. Starting from the distinction between nucleus and fringe in the stream of thought described by William James, it can be argued that our appreciation of a work of art is guided by a vague and blurred perception of a much more powerful content, of which we are not fully aware. Accordingly, a work of art is seen as a kind of metaphor of our mental (...) life, objectified to be able to reach out to a much larger audience. However, it is a “realistic” theory rooted in evolutionary psychology, which claims that our mind developed within a framework shaped by environmental pressures. The aesthetics illustrated by several novelists develops a paradigm for this theory. The search for the neuronal correlates of stream of consciousness allows to make a comparison with the recent findings of neuroaesthetics and to reject its claim that it is unnecessary to take phenomenology and psychology into account.

Kripke claims that there are necessary a posteriori truths and contingent a priori truths. These claims challenge the traditional Kantian view that (K) All knowledge of necessary truths is a priori and all a priori knowledge is of necessary truths. Kripke’s claims continue to be resisted, which indicates that the Kantian view remains attractive. My goal is to identify the most plausible principles linking the epistemic and the modal. My strategy for identifying the principles is to investigate two related questions. (...) Are there compelling general supporting arguments for (K)? Are there decisive counterexamples to (K)? My investigation uncovers two intuitively plausible principles that are not open to decisive counterexamples but which enjoy no compelling independent support. (shrink)

The “explanatory gap” is proposed to be the “hard problem” of consciousness research and has generated a great deal of recent debate. Arguments brought forward to reveal this gap include the conceivability of zombies or the “super-neuroscientist” Mary. These are supposed to show that the facts of consciousness are not a priori entailed by the microphysical facts. Similar arguments were already proposed by emergence theories in the context of the debate between mechanism and vitalism. According to synchronic emergentism, the property (...) of a system is emergent, when it cannot - in principle - be deduced from a complete description of the system’s components. Here, I argue that apart from phenomenal properties there are many other properties that, even though they are clearly physical, are not reductively explainable either. The explanatory gap of consciousness is therefore only a part of a much more general problem. (shrink)

Plain phenomenology explains theoretically salient mental or psychological distinctions with an appeal to their first-person applications. But it does not assume that warrant for such first-person judgment is derived from an explanatory theory constructed from the third-person perspective. Discussions in historical phenomenology can be treated as plain phenomenology. This is illustrated by a critical consideration of Brentano’s account of consciousness, drawing on some ideas in early Husserl. Dennett’s advocacy of heterophenomenology on the grounds of its supposed “neutrality” does not show (...) it is preferable to plain phenomenology. In fact the latter is more neutral in ways we ought to want, and permits a desirable use of first-person reflection that finds no place in the former. (shrink)

It is commonly held that there are two obstacles to precisely formulating the doctrine of physicalism: Hempel’s Problem, and Hume’s Problem.² Hempel’s Problem is that if physicalism is to be formulated in terms of physics—or in terms of any science, for the problem is fully general if it is a problem at all—whether to use the current or future science. If physicalism is formulated in terms of current physics, then it is most likely false because current physics is at least (...) very likely to be false and is perhaps known to be incomplete or inconsistent. If physicalism is formulated in terms of future physics, then (the worry goes) physicalism will prove to be trivial, vacuous, or simply of indeterminate content. Horgan offers no direct guidance on Hempel’s Problem, though he seems to adopt a future-physics view.³. (shrink)

Rosenberg does not provide arguments for some crucial premises in his argument against physicalism. In particular, he gives no independent argument to show that physicalists must accept the entry-by-entailment thesis. The arguments provided establish weaker premises than those that are needed. As a consequence, Rosenberg.

In this paper I challenge the core of David Chalmers' argument against materialism-the claim that "there is a logically possible world physically identical to ours, in which the positive facts about consciousness do not hold." First, I analyze the move from conceivability to logical possibility. Following George Seddon, I consider the case of a floating iron bar and argue that even this seemingly conceivable event has implicit logical contradictions in its description. I then show that the distinctions Chalmers employs between (...) primary and secondary intensions, and a priori and a posteriori entailment, break down upon close examination-with iron bars and with consciousness it is impossible to know where primary intensions end and secondary intensions begin. I extend this analysis of logical possibility to the famous zombie thought experiment and conclude not that a zombie world is logically impossible, but rather that, at present, the question is open. Finally, I show how a similar line of argument may be used to undermine the "Mary the color scientist" thought experiment as well. (shrink)

Charles Siewert presents a series of thought experiment based arguments against a wide range of current theories of phenomenal consciousness which I believe achieves a considerable measure of success. One topic which I think gets insufficient attention is the discussion of functionalism and I address this here. Before that I consider the intriguing issue, which is seldom considered but figures prominently at the close of Siewert's book, of the value of consciousness. In particular, I broach the question of whether the (...) value of consciousness has any impact on our theoretical understanding of consciousness. (shrink)

To be intrinsically valuable means to be valuable for its own sake. Moral philosophy is often ethically anthropocentric, meaning that it locates intrinsic value within humans. This paper rejects ethical anthropocentrism and asks, in what ways might nonhumans be intrinsically valuable? The paper answers this question with a wide-ranging survey of theories of nonhuman intrinsic value. The survey includes both moral subjects and moral objects, and both natural and artificial nonhumans. Literatures from environmental ethics, philosophy of technology, philosophy of art, (...) moral psychology, and related fields are reviewed, and gaps in these literatures are identified. Although the gaps are significant and much work remains to be done, the survey nonetheless demonstrates that those who reject ethical anthropocentrism have considerable resources available to develop their moral views. Given the many very high-stakes issues involving both natural and artificial nonhumans, and the sensitivity of these issues to how nonhumans are intrinsically valued, this is a vital project to pursue.

In this paper the explanatory gap of the philosophy of mind is explored, and found to have a similar structure even in different framings of the mind–body problem. This leads to the consideration that the MBP may be a special case of the more general whole-part problem: how do properties of wholes arise from the particular assembly of isolated parts? The conclusion is argued that only an approach of mereological holism offers solace from the explanatory gap problem, exchanging it for (...) a reverse explanatory gap problem that has more promising prospects for future solution, possibly in the form of integrated information theory. These considerations, along with the problem of explaining qualia lead to a proposed solution to the MBP in holistic cosmopsychism. (shrink)

Chalmers’ zombie argument against physicalism about consciousness supposes that every property of a composed physical system supervenes on the system’s fundamental constituents. In this paper, I discuss the significance of this supposition and I show that the philosophy of physics provides good grounds to resist it. As a result, I conclude that the zombie argument does not rule out a physicalist view of consciousness that conceives it as emergent in the sense of S-emergence. I finish by discussing some objections.
