In recent years the 'zombie argument' has come to occupy a central role in the case against physicalist views of consciousness, in large part because of the powerful advocacy it has received from David Chalmers.1 In this paper I seek to neutralize it by showing that a parallel argument can be run for physicalism, an argument turning on the conceivability of what I shall call anti-zombies. I shall argue that the result is a stand-off, and (...) that the zombie argument offers no independent reason to reject physicalism. (shrink)

In his ‘anti-zombie argument’, Keith Frankish turns the tables on ‘zombists’, forcing them to find an independent argument against the conceivability of anti-zombies. I argue that zombists can shoulder the burden, for there is an important asymmetry between the conceivability of zombies and the conceivability of anti-zombies, which is reflected in the embedding of a totality-clause under the conceivability operator. This makes the anti-zombie argument susceptible to what I call the ‘Modified (...) Incompleteness’, according to which we cannot conceive of scenarios. In this paper I also argue that conceiving of the zombie-situation is a good starting point for rendering the zombie argument plausible. (shrink)

This chapter discusses the anti‐materialist arguments that purport to show that conscious phenomena are genuinely new, nonphysical features of reality. The anti‐materialist claims that zombies are indeed conceivable. To see why this might make trouble for the materialist, the chapter considers again what is supposed to distinguish materialism from property dualism. Given the characterization of the difference between the materialist and the property dualist, it becomes clear why the conceivability of a zombie counts against materialism. One of (...) the most influential anti‐materialist arguments is the one presented by Frank Jackson. Jackson starts by assuming that the thesis of physicalism entails that all information is physical information. The most straightforward physicalist theory is the Central State Identity Theory (CSIT). According to this view (Smart 1959) conscious mental states, such as pains or visual sensations, are identical to certain states of the central nervous system. The principal objection to this view is its inherent “chauvinism”. (shrink)

John Stuart Mill considered his A System of Logic , first published in 1843, the methodological foundation and intellectual groundwork of his later works in ethical, social, and political theory. Yet no book has attempted in the past to engage with the most important aspects of Mill's Logic . This volume brings together leading scholars to elucidate the key themes of this influential work, looking at such topics as his philosophy of language and mathematics, his view on logic, induction and (...) deduction, free will, argumentation, ethology and psychology, as well as his account of normativity, kinds of pleasure, philosophical and political method and the "Art of Life.".

This chapter argues that two distinct, yet connected, contexts – Mill's “mental crisis” and his task as a “Logician” – led to the formation of two arguments on the value of art. On one hand, Mill argued that aesthetic cultivation was important as an end in itself. Excellence was to be pursued disinterestedly as part of a beautiful life. On the other, Mill argued aesthetic cultivation was important as a means to the utilitarian end – strengthening the social sympathies made (...) social happiness attainable. The first argument highlights what Mill thought was missing from the theory of his utilitarian predecessors, while the second brought Mill closer to this tradition, rather than moving him further away from it.

Most materialist responses to the zombie argument against materialism take either a “type-A” or “type-B” approach: they either deny the conceivability of zombies or accept their conceivability while denying their possibility. However, a “type-Q” materialist approach, inspired by Quinean suspicions about a priority and modal entailment, rejects the sharp line between empirical and conceptual truths needed for the traditional responses. In this paper, I develop a type-Q response to the zombie argument, one stressing the theory-laden nature (...) of our conceivability and possibility intuitions. I argue that our first-person access to the conscious mind systematically misleads us into thinking that the distinctive qualities of conscious experience—qualia—are nonfunctional. Qualia, I contend, are functional, even though they do not seem to be. To support my claim, I introduce the “meditations” of Rene Descartes’ zombie twin. This establishes the plausibility of an appearance/reality distinction for consciousness and it undermines various anti-materialist objections based on privileged first-person access. I conclude that the best overall theory posits an appearance/reality distinction for qualia, and this, for the type-Q materialist, is decisive. (shrink)

Several of the most compelling anti-materialist arguments are motivated by the supposed existence of an unbridgeable epistemic gap between first-person subjective knowledge about one’s own conscious experience and third-personally acquired knowledge. The two with which this paper is concerned are Frank Jackson’s ‘knowledge argument’ and David Chalmers’s ‘modal argument’. The knowledge argument and the modal argument are often taken to function as ‘two sides of the same coin … in principle each succeeds on its own, (...) but in practice they work best in tandem’. This paper disagrees with the above claim, and argues that when considered together the knowledge argument and modal arguments illuminate each other’s weaknesses. These weaknesses become apparent when we acknowledge the epistemic richness of the cognitive aspect of perceptual experience, and question the epistemic role that any non-cognitive aspect might play. Closer examination of judgments about what it’s like to have a perceptual experience reveals fundamental problems with the knowledge argument, and when these problems are exposed, the two arguments can no longer ‘buttress each other where help is needed’. It becomes clear that neither is likely to succeed on its own, and when taken together both are destabilized. (shrink)

This paper reassesses the criticism of the Lucas-Penrose anti-mechanist argument, based on Gödel’s incompleteness theorems, as formulated by Krajewski : this argument only works with the additional extra-formal assumption that “the human mind is consistent”. Krajewski argues that this assumption cannot be formalized, and therefore that the anti-mechanist argument – which requires the formalization of the whole reasoning process – fails to establish that the human mind is not mechanistic. A similar situation occurs with a (...) corollary to the argument, that the human mind allegedly outperforms machines, because although there is no exhaustive formal definition of natural numbers, mathematicians can successfully work with natural numbers. Again, the corollary requires an extra-formal assumption: “PA is complete” or “the set of all natural numbers exists”. I agree that extra-formal assumptions are necessary in order to validate the anti-mechanist argument and its corollary, and that those assumptions are problematic. However, I argue that formalization is possible and the problem is instead the circularity of reasoning that they cause. The human mind does not prove its own consistency, and outperforms the machine, simply by making the assumption “I am consistent”. Starting from the analysis of circularity, I propose a way of thinking about the interplay between informal and formal in mathematics. (shrink)

The anti-metaphysical argument against scientific realism is the following: Knowledge of unobservable entities implies metaphysical knowledge; There is no metaphysical knowledge. Therefore, there is no knowledge of unobservable entities. This argument has strangely received little attention in the profuse literature on scientific realism. This paper claims that the AMA is logically more fundamental than both the pessimistic meta-induction and the underdetermination argument. The second and main claim of this paper is that the instrumentalists’ use of AMA (...) is incoherent. The gist of my argument is that experimental knowledge requires minimally metaphysical knowledge, and that minimally metaphysical knowledge—when associated with empirical knowledge—suffices to yield a minimal knowledge of the unobservable. I then examine and reject two possible responses: minimally metaphysical instrumentalism and algebraic instrumentalism. (shrink)

Typically, anti-realists argue for the underdetermination of theory by the data on the basis of the claim that each theory has empirically equivalent rivals. Leplin has recently sought to show that, whatever the truth-value of this latter claim, it cannot play any positive role in an argument for underdetermination. I argue that Leplin’s attempt fails.

In this paper, we make a case for the disjunctive view of phenomenal consciousness: consciousness is essentially disjunctive in being either physical or non-physical in the sense that it has both physical and non-physical possible instances. We motivate this view by showing that it undermines two well-known conceivability arguments in philosophy of mind: the zombie argument for anti-physicalism, and the anti-zombie argument for physicalism. By appealing to the disjunctive view, we argue that two hitherto (...) unquestioned premises of these arguments are false. Furthermore, making use of the resources of this view, we formulate distinct forms of both physicalism and anti-physicalism. On these formulations, it is easy to see how physicalists and anti-physicalists can accommodate the modal intuitions of their opponents regarding zombies and anti-zombies. We conclude that these formulations of physicalism and anti-physicalism are superior to their more traditional counterparts. (shrink)

Conceptual engineering concerns the assessment and improvement of our concepts. But how can proposals to engineer concepts be implemented in the real world? This is known as the implementation challenge to conceptual engineering. In this paper, I am concerned with the meta-philosophical implications of the implementation challenge. Specifically, must we overcome the implementation challenge prior to undertaking conceptual engineering? Some critics have recently answered this question affirmatively. I intend to show that they are mistaken. I argue as follows. First, successful (...) implementation is not an integral part of conceptual engineering. Second, the idea that the value of conceptual engineering relies on successful implementation is in tension with widespread assumptions about normative theorizing. (shrink)

Beginning with the paradoxes of zombie twins, we present an argument that dualism is both true and false. We show that avoiding this contradiction is impossible. Our diagnosis is that consciousness itself engenders this contradiction by producing contradictory points of view. This result has a large effect on the realism/anti-realism debate, namely, it suggests that this debate is intractable, and furthermore, it explains why this debate is intractable. We close with some comments on what our results mean (...) for metaphysics and philosophy, in general. (shrink)

claim that his thought experiment shows that a currently living person is not a random sample is refuted. His thought experiment is reduced to a probability model, and is shown to be identical to one previously developed by Dieks. The status of the Doomsday Argument is left unresolved, since Dieks's refutation attempt is disputed in the literature.

I argue that no successful version of Williamson's anti‐luminosity‐argument has yet been presented, even if Srinivasan's further elaboration and defence is taken into account. There is a version invoking a coarse‐grained safety condition and one invoking a fine‐grained safety condition. A crucial step in the former version implicitly relies on the false premise that sufficient similarity is transitive. I show that some natural attempts to resolve this issue fail. Similar problems arise for the fine‐grained version. Moreover, I argue (...) that Srinivasan's defence of the more contentious fine‐grained safety condition is also unsuccessful, again for similar reasons. (shrink)

I develop advice to the reductionist about consciousness in the form of a transcendental argument that depends crucially on the sorts of knowledge claims concerning consciousness that, as crucial elements in the anti-reductionists’ epistemicgap arguments, the anti-reductionist will readily concede. The argument that I develop goes as follows. P1. If I know that I am not a zombie, then phenomenal character is (a certain kind of) conceptualized egocentric content. P2. I know that I am not (...) a zombie. P3. Phenomenal character is (a certain kind of) conceptualized egocentric content. P4. Fixing my physical properties fixes my conceptualized egocentric contents. C. Fixing my physical properties fixes my phenomenal properties. (shrink)

Materialism/physicalism that generally dominates in the contemporary analytic philosophy is challenged by fairly powerful anti-materialist arguments, notably the zombie argument (most influentially defended by David Chalmers) and the knowledge argument (the most widely discussed version of which was advanced and defended by Frank Jackson). These arguments highlight the explanatory gap from the physical (which, if materialism is true, should constitute everything that exists, including consciousness) to phenomenal mental states, the principal impossibility to explain the latter by (...) the former, and from this conclude that phenomenal consciousness is not physical, and so materialism is false. Materialist philosophers attempt to neutralize these arguments in several ways, the most influential of which is the strategy of phenomenal concepts. This article analyzes the main points of this debate with a focus on the knowledge argument, examines and responds to the main objections to the knowledge argument — that it should be mistaken because the alternative is epiphenomenalism, which is unacceptable; that no new knowledge but only new capacities and/or acquaintance are involved; that the knowledge is the same but in different forms; that the knowledge argument affects only type physicalism but not token physicalism. The case is made that psychophysical identities assumed by a posteriori physicalism are unexplainable in principle, and the postulation of brute unexplainable psychophysical identities glossed over by the strategy of phenomenal concepts amounts to dogmatic commitment (motivated by scientism) to a view despite its apparent falsity and its unintelligibility (the impossibility to explain how it can be true), made less unpalatable by offering an ad hoc theory about the mindbrain arrangement that makes us unable to see how the view can be true. As opposed to this, the position of the supporters of the knowledge argument and the zombie argument can be seen as guided by the principle of rational trust in obviousness and our capacities of judgement.

De-extinction raises anew ontological and epistemological problems that have engaged environmental philosophers for decades. This essay re-examines these issues to provide a fuller understanding—and a critique—of de-extinction. One of my claims is that de-extinction as a philosophical problem merely recycles old issues and debates in the field (hence, “zombie” arguments). De-extinction is a project that arises out of the assertion of human domination of the natural world. Thus the acceptance of de-extinction as an environmental policy is an expression of (...) a human-nature relationship that disvalues the natural world and subjugates nature completely to the interests of humanity.

This article proposes a way of blocking the zombie argument against materialism. The central idea—which can be motivated in various ways, but which I will motivate by drawing on recent work by Wolfgang Schwarz—is that sentences reporting conscious experience are modally inert, roughly in the sense that adding them to a description of a metaphysically possible scenario always results in a description of a metaphysically possible scenario. This is notable in that it leads to a way of blocking (...) the zombie argument, which is perfectly compatible with modal rationalism and with the view that conceivability entails possibility. (shrink)

In this paper, I argue that the first and the third premises of the zombie argument cannot be jointly true: zombies are either inconceivable beings or the possible existence of them does not threaten the physicalist standpoint. The tenability of the premises in question depends on how we understand the concept of a zombie. In the paper, I examine three popular candidates to this concept, namely zombies are creatures who lack consciousness, but are identical to us in (...) their (a) functional organization, (b) entire physical makeup, and (c) microphysical structure. The main aim of the paper is to argue that none of these conceptions conveys a consistent zombie-concept to us, which, at the same time, would be dangerous for physicalism. In the conclusion, I argue that the source of this failure can be found in the logical fallaciousness of the argument, namely the premises simply presuppose the truth of the conclusion. (shrink)

In contemporary philosophy of science, the no-miracles argument and the pessimistic induction are regarded as the strongest arguments for and against scientific realism, respectively. In this paper, I construct a new argument for scientific realism which I call the anti-induction for scientific realism. It holds that, since past theories were false, present theories are true. I provide an example from the history of science to show that anti-inductions sometimes work in science. The anti-induction for scientific (...) realism has several advantages over the no-miracles argument as a positive argument for scientific realism. (shrink)

Abstract An anonymous manuscript from the fourteenth or early fifteenth century, recently discovered, apparently transmitted Thierry of Chartres's philosophical theology to Nicholas of Cusa around 1440. Yet the author of the treatise is not endorsing Thierry's views, as both Cusanus and modern readers have assumed, but in fact is writing in order to refute them. Curiously the author never mentions Thierry's best known triad of unitas, aequalitas and conexio . But a careful comparison of the structure of the author's (...) class='Hi'>argument to Thierry's extant works shows that the author was nevertheless quite familiar with the Breton master's writings. The reatise's author offers an incisive critique of Thierry's theory of “four modes of being“ and rejects two of the modes in particular. From this new perspective, the manuscript can be valued as the first known evidence of Thierry of Chartres's late medieval reception. (shrink)

In this paper I argue against the received view that the anti‐nativist arguments of Book I of Locke's Essay conclusively challenge nativism. I begin by reconstructing the chief argument of Book I and its corollary arguments. I call attention to their dependence on (what I label) “the Awareness Principle”, viz., the view that there are no ideas in the mind of which the mind either isn't currently aware or hasn't been aware in the past. I then argue that (...) the arguments' dependence on this principle is question begging on two counts. Unless this principle is defended, Locke's arguments beg the question against Descartes and Leibniz because their nativism implies the denial of the Awareness Principle. And even when Locke defended the principle, his arguments remain question begging because they presuppose the empiricism they aim to prove. The disclosure of the question‐begging status of these arguments debunks a seemingly powerful way of attacking nativism. (shrink)

In the Anticipations, Kant defends the claim that all sensations must register on a purely subjective scale of response to stimuli, in order for sensation to be a possible source of knowledge. In this paper, I argue that Kant defends this claim in response to “scholasticism” or transcendental realism about sensation. The fact that all sensations are measurable on a subjective scale is the a priori content of the principle of the Anticipations, and, according to Kant, is a necessary condition (...) for building any systematic analysis of sensation. The anti-metaphysical arguments in the “Anticipations of Perception” are key building blocks of Kant’s transcendental idealism. (shrink)

This paper discusses the zombie argument and other antiphysicalist arguments presented by David Chalmers in his book, The Conscious Mind . It is argued that both premises of the zombie argument -- the conceivability of zombies and the conceivabilitypossibility thesis --cannot be made simultaneously plausible without additional argument in support of one of the premises. The best strategy for the proponent of the zombie argument is identified as limiting the conceivability-possibility thesis to an (...) idealized notion of conceivability, and arguing separately for the conceivability of zombies in this idealized sense. Out of Chalmers' main arguments, the argument from epistemic asymmetry and the argument from absence of analysis are considered in this role. It is argued that, while either of the arguments would, if sound, be appropriate for the role, the first is subject to decisive counter-arguments. The second, on the other hand, is found not only suitable to support the zombie argument, but also more convincing in that its premises are less controversial. Since the argument from absence of analysis also establishes the falsity of physicalism directly by itself, if sound, it can be seen to render the zombie argument redundant. (shrink)

Many non-physicalists, including Chalmers, hold that the zombie argument succeeds in rejecting the physicalist view of consciousness. Some non-physicalists, including, again, Chalmers, hold that quantum collapse interactionism, i.e., the idea that non-physical consciousness causes collapse of the wave function in phenomena such as quantum measurement, is a viable interactionist solution for the problem of the relationship between the physical world and the non-physical consciousness. In this paper, I argue that if QCI is true, the zombie argument (...) fails. In particular, I show that if QCI is true, a zombie world physically identical to our world is impossible because there is at least one law of nature, a fundamental law of physics in particular, that exist only in the zombie world but not in our world. This shows that philosophers like Chalmers are committing an error in endorsing the zombie argument and QCI at the same time. (shrink)

This paper argues for a possible-worlds interpretation of the arguments marshalled by Socrates against Protagoras in Plato’s Theaetetus. Specifically, it reads Protagoras’ position as implying a limited form of modal realism, and evaluates both the self-refutation sequence at 170a–71d and the Future Argument at 177c–9c on the basis of this reading. It emerges that Socrates’ project is only partly successful: while the three main arguments of the self-refutation sequence force Protagoras into ever more awkward and metaphysically top-heavy positions, and (...) the Future Argument is psychologically compelling, these arguments do not force a collapse of the relativist position. Protagoras can still defend himself, though the cost is high. (shrink)

The dissertation addresses the mind-body problem, and in particular, the problem of how to fit phenomenal consciousness into the rest of reality. Phenomenal consciousness - the what it’s like feature of experience - can appear to the scientifically inclined philosopher to be deeply mysterious. It is difficult to understand how the swirl of atoms in the void, the oscillation of field values, the firing of synapses, or anything physical can add up to the smells, tastes, feelings, moods, and so forth (...) that comprise our phenomenal experience. There is a series of arguments - the so-called “Conceivability Arguments” - that spells out this puzzlement. If this arguments are successful then there is no place for phenomenal consciousness in a completely physical reality. The main conclusion of this dissertation is that the Conceivability Arguments are all dependent on a flawed premiss, and that therefore these arguments - perhaps the most powerful among anti-physicalist arguments - all fail. Conceivability Arguments begin with the premiss that we can conceive of any physical or functional facts obtaining without there being any phenomenal experience at all. This is sometimes expressed by saying that zombies (i.e., beings that are our physical and functional duplicates, but possess no phenomenal experiences) are conceivable. The claim that zombies are conceivable does not have to do with our powers of imagination, or our psychological abilities, but rather with the nature of physical and phenomenal concepts. The reason that zombies are claimed to be conceivable is that each person’s thinking about phenomenal properties is completely dependent on her first person acquaintance with her own experience. From this assertion of conceivability it is inferred that zombies are genuinely possible. And this conclusion is incompatible with physicalism as that doctrine is usually understood. I argue that these arguments all fail; they are refuted by a master argument that I call “the Zombie Refutation.” The reason they fail has to do with the very nature of phenomenal concepts that gives rise to the conceivability of zombies. Because of the special nature of these concepts, the principle underlying the Conceivability Arguments - that principle that links conceivability and possibility - turns out to be self-refuting. Thus, the zombies that the Conceivability Arguments supposedly demonstrate to be possible, return to undermine those very arguments; a fitting revenge. (shrink)

In a recent book devoted to the axiology of theism, Kirk Lougheed has argued that the ‘complete understanding’ argument should be numbered among the arguments for anti-theism. According to this argument, God’s existence is detrimental to us because, if a supernatural and never completely understandable God exists, then human beings are fated to never achieve complete understanding. In this article, I argue that the complete understanding argument for anti-theism fails for three reasons. First, complete understanding (...) is simply impossible to achieve. Second, even if achieving complete understanding were possible, it would not be beneficial. Third, the only type of complete understanding that is possible to achieve and is beneficial to human beings is the understanding of that which is of primary importance to us, and not the understanding of everything, as Lougheed seems to assume. God can grant us complete understanding of that which is of primary importance to us. As a consequence, God’s existence ends up being beneficial and not detrimental to us. (shrink)

Within the discourse surrounding mind-body interaction, mental causation is intimately associated with non-reductive physicalism. However, such a theory holds two opposing views: that all causal properties and relations can be explicated by physics and that special sciences have an explanatory role. Jaegwon Kim attempts to deconstruct this problematic contradiction by arguing that it is untenable for non-reductive physicalists to explain human behavior by appeal to mental properties. In combination, Kim’s critique of mental causation and the phenomenal concept strategy serves as (...) an effectual response to the anti-physicalist stance enclosed within the Knowledge Argument and the Zombie Thought Experiment.

This paper discusses a wide range of anti-naturalistic argument from reason due to Balfour, Haldane, Joad, Lewis, Taylor, Moreland, Plantinga, Reppert, and Hasker. I argue that none of these arguments poses a serious challenge to naturalists who are identity theorists. Further, I argue that some of these arguments do not even pose prima facie plausible challenges to naturalism. In the concluding part of my discussion, I draw attention to some distinctive differences between Hasker’s anti-naturalistic arguments and the (...) other anti-naturalistic arguments mentioned above.

Conventional approaches in pro- or anti-democratic discourses often scrutinize the efficacy of leadership based on its outcomes, or explore the moral foundations of different systems. Contrary to these approaches, my argument presented in this paper is grounded in the inherent psychological desire to be heard and accepted. I posit that the essence of democracy resides in free discussion — a value even embraced by committed anti-democrats in the context of debates, as their acknowledgment hinges on it. This (...) article presents an argument, developed based on my experience in actual debates called The Paradox of Anti-Democratic Arguments, to counter anti-democratic debaters who question the legitimacy of democratic norms. The article discusses the practical application of the argument in debates and casual discussions, its limitations and highlights the underlying psychological processes that make the argument effective in the context of Leon Festinger’s theory of cognitive dissonance.

The conceivability argument against materialism, originally raised by Saul Kripke and then reformulated, among others, by David Chalmers holds that we can conceive of the distinctness of a phenomenal state and its neural realiser, or, in Chalmers’ variation of the argument, a zombie world. Here I argue that both phenomenal and natural kind terms are ambiguous between two senses, phenomenal and natural, and that the conceivability argument goes through only on one reading of a term. Thus, (...) the antimaterialist has to provide some reasons independent of anti-materialism itself to favour that reading of a term that supports his or her argument. Given that there are no such independent reasons, I conclude that we should put more weight on empirical considerations than on a priori discussion in resolving the question concerning the identity between a phenomenal state and its neural realiser.

In a recent paper, Guy Kahane asks whether God’s existence is something we should want to be true. Expanding on some cryptic remarks from Thomas Nagel, Kahane’s informative and wide-ranging piece eventually addresses whether personal anti-theism is justified, where personal anti-theism is the view that God’s existence would make things worse overall for oneself. In what follows, I develop, defend, but ultimately reject the Meaningful Life Argument, according to which if God’s existence precludes the realization of certain (...) goods that seem to an agent to constitute a meaningful life, it is rational for an agent both to believe that personal anti-theism is true and to prefer that God not exist.
