This paper examines the legitimacy of two common methodologies within philosophy: thought experiments and conceptual analysis. In particular, I examine the uses to which these two methodologies have been put within modal epistemology. I argue that, although both methods can be used to reveal conditional essentialist claims (e.g. necessarily: if x is water, then x is H20), neither can be used to reveal the de re essentialists claims (e.g. x is water and x is essentially H20) they’re often taken to (...) reveal.

A prominent objection to supervenience physicalism is that a definition of physicalism in terms of supervenience allows for physicalism to be compatible with nonphysicalist outlooks, such as certain forms of emergentism. I take as my starting point a recent defense of supervenience physicalism from this objection. According to this line of thought, the subvenient base for emergent properties cannot be said to be purely physical; rather, it is “polluted” with emergent features in virtue of necessarily giving rise to them. Thus, (...) if emergentism is true, it is false that everything supervenes on physical properties. I argue that this gives way to a new challenge for supervenience physicalism. The challenge, roughly, is to distinguish the emergentist’s “polluted” base from a physical supervenience base; that is, to give conditions under which the subvenient base is not “polluted” by supervenient properties. The problem, I argue, is that it is hard to see how this can be done without collapsing supervenience physicalism into alternative approaches to physicalism. I thus argue that if the present defense of supervenience physicalism succeeds in defending the adequacy of a supervenience-based definition of physicalism, it does so by compromising its uniqueness.

Legal philosophers divide over whether it is possible to analyze legal concepts without engaging in normative argument. The influential analysis of legal rights advanced by Jules Coleman and Jody Kraus some years ago serves as a useful case study to consider this issue because even some legal philosophers who are generally skeptical of the neutrality claims of conceptual analysts have concluded that Coleman and Kraus's analysis manages to maintain such neutrality. But that analysis does depend in subtle but important ways (...) on normative claims. Their argument assumes not only a positivist concept of law, but also that it counts in favor of an analysis of legal rights that it increases the number of options available to legal decisionmakers. Thus, whether Coleman and Kraus's analysis is right in the end depends on whether those normative assumptions are justified. If even their analysis, which makes the thinnest of conceptual claims, depends on normative premises, that fact serves as strong evidence of the difficulty of analyzing legal concepts while remaining agnostic on moral and political questions.

Naturalists who conceive of knowledge as a natural kind are led to treat ‘knowledge’ as a natural kind term. ‘Knowledge,’ then, must behave semantically in the ways that seem to support a direct reference theory for other natural kind terms. A direct reference theory for ‘knowledge,’ however, appears to leave open too many possibilities about the identity of knowledge. Intuitively, states of belief count as knowledge only if they meet epistemic criteria, not merely if they bear a causal/historical relation to (...) the term. I will develop this objection and show that it is grounded in modal considerations central to Kripke’s work on reference. I will also argue that a more plausible externalist semantics for natural kind terms disarms the objection. (shrink)

Perhaps the two main contemporary formulations of ethical naturalism – Synthetic Ethical Naturalism (SEN) and Analytical Descriptivism – seem to conflict with plausible views about cases where moral debate and disagreement is possible. Both lack safeguards to avoid divergence of reference across different communities, which can scupper the prospects for genuine moral disagreement. I explore the prospects for supplementing both views with Lewis's notion of eligibility, arguing that this can solve the problem for a modified form of analytical descriptivism, and (...) for a modified form of SEN too (though perhaps more controversially). I close by considering the appropriateness of using the notions of eligibility and joint-carving in ethics. (shrink)

The paper addresses the question whether semantic naturalism is undermined by the thought that semantic concepts are normative.

While historically prominent theories of truth such as the correspondence theory, coherentism, pragmatism, verificationism, and instrumentalism diverge in many ways, they converge in at least one fundamental respect. They are all monist theories of truth. They incorporate the thesis that there is one property—and one property only—in virtue of which propositions can be true. The truth pluralist, on the other hand, rejects this idea. There are several properties in virtue of which propositions can be true. This article offers a survey (...) of recent work on alethic pluralism—presenting various incarnations of the view, objections leveled against them, and various lines of response available to pluralists.

This paper articulates two constraints on an acceptable account of meaning: (i) accessibility: sameness of meaning affords an immediate appearance of de jure co-reference, (ii) flexibility: sameness of meaning tolerates open-ended variation in speakers' substantive understanding of the reference. Traditional accounts of meaning have trouble simultaneously satisfying both constraints. I suggest that relationally individuated meanings provide a promising way of avoiding this tension. On relational accounts, we bootstrap our way to de jure co-reference: the subjective appearance of de jure co-reference (...) helps make it the case that two token representations really do co-refer.

This paper advances a version of physicalism which reconciles the “a priori entailment thesis” (APET) with the analytic independence of our phenomenal and physical vocabularies. The APET is the claim that, if physicalism is true, the complete truths of physics imply every other truth a priori. If so, “cosmic hermeneutics” is possible: a demon having only complete knowledge of physics could deduce every truth about the world. Analytic independence is a popular physicalist explanation for the apparent “epistemic gaps” between phenomenal (...) and physical truths. The two are generally seen as incompatible, since the demon’s deductions seem to presuppose analytic connections between physical and phenomenal terms. I begin by arguing, in support of the APET, that implications from the complete truths of physics to phenomenal truths cannot be a posteriori. Such implications are (according to the physicalist) necessarily true. But they cannot be Kripke-style a posteriori necessities, since (according to the physicalist) the complete truths of physics fix any relevant a posteriori facts about the reference of terms. I then show how the physicalist can turn the tables: the demon can exploit the physical fixing of reference to bridge the gap between the vocabularies, by deducing when phenomenal and physical terms co-refer. This opens the way for a “type-C” physicalism, which accepts in-principle deducibility while still appealing to analytic independence to explain why we (who are not demons) find it impossible to see phenomenal-physical connections a priori.

According to Conceptualism, philosophy is an independent discipline that can be pursued from the armchair because philosophy seeks truths that can be discovered purely on the basis of our understanding of expressions and the concepts they express. In his recent book, The Philosophy of Philosophy, Timothy Williamson argues that while philosophy can indeed be pursued from the armchair, we should reject any form of Conceptualism. In this paper, we show that Williamson’s arguments against Conceptualism are not successful, and we sketch (...) a way to understand understanding that shows that there is a clear sense in which we can indeed come to know the answers to (many) philosophical questions purely on the basis of understanding.

This article seeks to explore the conceptual structure and moral standing of an idea that has received almost no attention from analytical philosophers: self-censorship. It is argued that at the heart of the concept is a tension between the thoughts of the self-censor as, on the one hand, the author, and on the other, the instrument, of the censorship. Which of these aspects is emphasised also importantly helps shape how self-censorship is viewed normatively. Focusing on authorship tends to lead to (...) seeing self-censorship as more akin to a freely chosen act of self-restraint, while focusing on the self-censor as instrument presents it as one specific form of ordinary censorship. It is the tension between these two aspects that accounts for the moral ambivalence that is often felt towards the practice of self-censorship. (shrink)

Natural kind terms have exercised philosophical fancy ever since Kripke, in Naming and Necessity, claimed them to be rigid designators. He there drew attention to the peculiar, name-like behavior of a family of prima facie loosely related general terms of ordinary English: terms such as ‘water’, ‘tiger’, ‘heat’, and ‘red’. Just as for ordinary proper names, Kripke argued that such terms cannot be synonymous with any of the definite descriptions ordinary speakers associate with them. Rather, the name-like behavior of these (...) so-called natural kind terms is to be explained, just as in in the case of proper names, by the doctrine of rigid designation. And as a consequence of thus extending the notion of rigid designation to general terms, he famously endorsed the claim that so-called ‘theoretical identifications’, i.e. statements like (1) Water is H2O, are necessary, if true.

I take up the task of examining how someone who takes seriously the ambitious programme of conceptual analysis advocated by the Canberra School can minimise the eliminative consequences which I argue the Ramsey-Carnap-Lewis recipe of conceptual analysis is likely to have for many folk discourses. The objective is to find a stable means to preserve the constative appearance of folk discourse and to find it generally successful in its attempts to describe an external world, albeit in non-scientific terms that do (...) not reflect the nature of things. The view I settle on, quasi-fictionalism, is modelled on a modified descriptivist version of Kendall Walton’s account of prop-oriented games of make-believe. (shrink)

It is possible to pursue philosophy with a clarificatory end in mind. Doing philosophy in this mode neither reduces to simply engaging in therapy or theorizing. This paper defends the possibility of this distinctive kind of philosophical activity and gives an account of its product—non-theoretical insights—in an attempt to show that there exists a third, ‘live’ option for understanding what philosophy has to offer. It responds to criticisms leveled at elucidatory philosophy by defenders of extreme therapeutic readings and clearly demonstrates (...) that in rejecting the latter one cannot assume Wittgenstein’s approach to philosophy was theoretically based by default.

Moral discourse allows for speakers to disagree in many ways: about right and wrong acts, about moral theory, about the rational and conative significance of moral failings. Yet speakers’ eccentricities do not prevent them from engaging in moral conversation or from having (genuine, not equivocal) moral disagreement. Thus differences between speakers are compatible with possession of moral concepts. This paper examines various kinds of moral disagreements and argues that they provide evidence against conceptual-role and informational atomist approaches to understanding our (...) moral concepts. Conceptual role approaches fail because they cannot account for shared concepts among speakers with different commitments to the practical and conative ramifications of moral judgments. Informational atomist views fail because speakers need not be locked on to the same moral properties to share moral concepts. (shrink)

Kripke's argument against the identity theory in the philosophy of mind runs as follows. Suppose some psychophysical identity statement S is true. Then S would seem to be contingent at least in the sense that S seems possibly false. And given that seeming contingency entails genuine contingency when it comes to such statements S is contingent. But S is necessary if true. So S is false. This entry considers responses to each of the three premises. It turns out that each (...) response does not fully withstand scrutiny, and so Kripke's conclusion is hard to resist. Section 1 lays out Kripke's argument, and Sections 2 to 4 then discuss responses to each of the three premises respectively. (shrink)

This paper is an investigation into the nature of physicalism as well as to the possibility of formulating physicalism as a supervenience thesis. First, I review the motivation for finding a supervenience thesis that characterizes physicalism. Second, I briefly survey the types of supervenience theses that have been proposed as necessary (or, in some cases, as necessary and sufficient) for physicalism. Third, I analyze the recent supervenience thesis proposed by Frank Jackson and expounded upon by Gene Witmer. Jackson claims the (...) supervenience thesis is both necessary and sufficient for physicalism; Witmer has proposed a different interpretation of one of the Jackson’s key notions and has suggested an amended supervenience thesis that is, if not sufficient, at least necessary for physicalism. However, I will argue that neither Jackson’s nor Witmer’s supervenience theses as stated are necessary for physicalism. (shrink)

NRP is a family of views differing by how they understand “reduction” and “physicalism.” Following Kim I understand the non-reduction as holding that some events and properties are distinct from any physical events and properties. A necessary condition for physicalism is that mental properties, events, and laws supervene on physical ones. Kim allows various understandings of “supervenience” but I think that physicalism requires at least the claim that any minimal physical duplicate of the actual world is a duplicate simpliciter. Some (...) complications aside this means that true mental propositions, e.g. Jaegwon is thinking about sailing, are metaphysically entailed by true physical propositions. Kim says that supervenience is too weak to capture the root idea of physicalism that mental property instantiations depend on physical property instantiations so he adds that the mental depends on the physical. One way in which this dependance might be spelled out is that mental properties are higher order functional properties whose instantiations are realized by instantiations of physical properties. An event is an instantiation of a property by an individual and a time. A mental event is the instantiation of a mental property. Not every predicate expresses a genuine property. Kim further suggests that properties are individuated, at least partly, by nomological and causal relations. For physicalism to have content something must be said about the difficult issue of characterizing the physical. Kim’s view seems to be that the micro-physical properties of ideal physics are physical. He also counts as physical properties that are conjunctions and aggregates of micro-physical properties and higher level properties defined over lower-level physical properties.. Since these latter two classes of properties supervene on the micro-properties and laws there is no need to include them in the supervenience base. (shrink)

A posteriori Moral Naturalism posits a posteriorimoral/naturalistic identities. Versions of this view thatposit necessary identities purport to rely on theKripke/Putnam doctrine of scientific essentialism.Versions that posit only contingent identities requirethat moral terms are non-rigid designators. I argue thatmetaethics does not fall within the scope of scientificessentialism and that moral terms are not non-rigid designators.

Allan Gibbard’s strategy in his new book is to begin by describing a psychology of thinking and planning that certain agents might instantiate, then to argue that this psychology involves an ‘expressivism’ about thought that bears on what to do, and, finally, to try to show that ascribing that same psychology to human beings would explain the way we deploy various concepts in practical and normative deliberation. The idea is to construct an imaginary normative psychology, purportedly conforming to expressivist specifications, (...) and then to campaign for the hypothesis that that psychology is ours and that we ourselves conform to those specifications. The upshot is an original and intriguing argument for the claim that ‘expressivism’, as Gibbard understands it, is sound. There is more in the book than that bare argument. Filling out the strategy pursued, for example, the volume contains useful discussions of a number of current debates (chs 2, 12), an enlightening argument that the strategy survives the introduction of the notion that a concept can have a character distinct from its content (ch. 6), and an extended set of reflections on how far the point of view defended leaves room for the idea of gaining normative knowledge (pt. 4). But I shall ignore those aspects of the book in this commentary; the focus is on its central argument. My approach will be to reconstuct the main stages in the Aufbau of our normative psychology that Gibbard provides, emphasizing some crucial points that are passed over rather quickly, and then to suggest on the basis of this reconstruction that the more natural lesson to derive is not an expressivist one. Although I break with Gibbard in that way, however, I have great admiration for the book. Thinking How to Live is a sharp, fresh and invigorating treatment of the main issues of metaethics. (shrink)

Inspired by two-dimensional modal logic, some have sought to provide analyses of the notion of the contingent a priori which identify the a priori with truths which have a necessary diagonal. I argue that these analyses fail insofar as they miss the crucial epistemic aspect of the a priori. Augmenting these analyses with specifically epistemic accounts might be possible, but the interest would then reside in these epistemic accounts of the a priori and not in the formal models.

The idea of truthmakers is important for doing serious metaphysics, since a truthmaker principle can give us important guidance in finding out what we would like to include into our ontology. Recently, David Lewis has argued against Armstrong’s argument that a plausible truthmaker principle requires us to accept facts. I would like to take a close look at the argument. I will argue in detail that the Humean principle of recombination on which Lewis relies is not plausible (independently of the (...) issue of facts). Then I will show that the right truthmaker principle that vindicates facts is superior to the modified truthmaker principle that Lewis has proposed. This will lead into the topic of being and existence. It turns out that truthmaking and facts are plausible, well suited for one another, and very coherent with a plausible conception of being.

A consideration of the benefits of taking physicalism to be necessarily true if true, against the standard view that physicalism is at best contingently true. Presented at the 2006 Central Division meeting of the APA, in the session Themes from Jaegwon Kim, sponsored by the Society for Asian and Asian-American Philosophy.

Suppose P is the conjunction of all truths statable in the austere vocabulary of an ideal physics. Then phsicalists are likely to accept that any truths not included in P are different ways of talking about the reality specified by P. This ‘redescription thesis’ can be made clearer by means of the ‘strict implication thesis’, according to which inconsistency or incoherence are involved in denying the implication from P to interesting truths not included in it, such as truths about phenomenal (...) consciousness. Commitment to the strict implication thesis cannot be escaped by appeal to a posteriori necessary identities or entailments. A minimal physicalism formulated in terms of strict implication is preferable to one based on a priori entailment. (shrink)

Although philosophers have puzzled about color for millennia, the recent explosion in philosophical interest in the topic can largely be traced to C. L. Hardin’s widely-read and deservedly-praised Color for Philosophers: Unweaving the Rainbow [Hardin, 1988]. While Hardin has had no more than the usual, limited success in convincing other philosophers to adopt the substance of his views, he has been quite influential about a point of philosophical methodology: he has convinced many that responsible philosophical work on color simply must (...) make contact with the vast body of empirical color science, and thereby has effected an enormous (and to my mind, extremely salutary) change in the terms of recent philosophical discussion of color.¹ Indeed, writers have been so eager to take Hardin’s lesson on board that one is hard-pressed to find a recent philosophical book on color that does not acknowledge it, crediting Hardin by name.

Kripke and Putnam have convinced most philosophers that we cannot do metaphysics of nature by analysing the senses of natural kind terms -- simply because natural kind terms do not have senses. Neo-descriptivists, especially Frank Jackson and David Chalmers, believe that this view is mistaken. Merging classical descriptivism with a Kaplan-inspired two-dimensional framework, neo-descriptivists devise a semantics for natural kind terms that assigns natural kind terms so-called 'primary intensions'. Since primary intensions are senses by other names, Jackson and Chalmers conclude (...) that we can and should do metaphysics of nature by analysing the natural kind concepts competent speakers possess. I argue that neo-descriptivism does not provide a suitable basis for doing this kind of metaphysics. I first of all give a detailed account of the neo-descriptivist semantics and deflate the intuitive support neo-descriptivists try to draw from their case of the XYZ-world. I then present three arguments -- the Argument from Ignorance, the Argument from Conceptual Analysis, and the Argument from Laziness. Taken together, these arguments undermine the neo-descriptivist analysis of natural kind terms. I conclude that natural kind terms do not have senses, that we cannot do metaphysics of nature by analysing the senses of our kind terms, and that the Kripke-Putnam account still provides the best semantics for natural kind terms we have.

Charles Siewert has given us an ingenious thought experiment involving a limited lack of conscious experience. The possibility of the described case is incompatible with a number of popular theories of consciousness. Siewert acknowledges, however, that this possibility is not a direct threat to "hidden feature" theories. I aim to do two things: first, strengthen his defense of the claim that the case is genuinely possible by considering and rejecting some further attempts to explain away our temptation to believe it (...) possible; and second, to explore how a hidden feature approach could be developed and made plausible.

Dans ce livre très original, Markus Gabriel avance une théorie du soi humain qui surmonte les blocages inhérents aux positions standards en philosophie de l’esprit contemporaine. Son point de vue, le néo-existentialisme, est intégralement antinaturaliste, en ce sens qu’il rejette toute théorie selon laquelle l’ensemble de nos meilleures connaissances scientifiques naturelles serait pleinement capable de rendre compte de l’esprit humain. L’auteur montre plutôt que l’esprit humain consiste en une prolifération ouverte de vocabulaires mentalistes. Leur rôle dans la forme de vie (...) humaine consiste à rendre compte du fait que l’être humain ne se fond pas simplement dans la nature inanimée et le reste du règne animal. Les humains s’appuient sur un autoportrait qui les situe dans un contexte aussi large que possible au sein de l’univers. Ce qui distingue cet autoportrait de notre connaissance de la réalité naturelle, c’est que nous changeons en vertu de nos croyances, vraies ou fausses, au sujet de nous-mêmes. (shrink)

The advent of intelligent artificial systems has sparked a dispute about the question of who is responsible when such a system causes a harmful outcome. This paper champions the idea that this dispute should be approached as a conceptual engineering problem. Towards this claim, the paper first argues that the dispute about the responsibility gap problem is in part a conceptual dispute about the content of responsibility and related concepts. The paper then argues that the way forward is to evaluate (...) the conceptual choices we have, in the light of a systematic understanding of why the concept is important in the first place—in short, the way forward is to engage in conceptual engineering. The paper then illustrates what approaching the responsibility gap problem as a conceptual engineering problem looks like. It outlines argumentative pathways out of the responsibility gap problem and relates these to existing contributions to the dispute. (shrink)

In this thesis, I will explore the epistemological evolutionary debunking arguments in meta-ethics. I will defend these arguments by accomplishing two tasks: I will offer the best way to understand the EDA and I will also respond to two strongest objections to the EDA. Firstly, in Part I of this thesis, I will offer my account of how the EDA should be best formulated. I will start from how evolution has significantly influenced our moral beliefs. I will then explain why, (...) due to their evolutionary origin, our moral beliefs are not tracking the moral truth reliably. Furthermore, I will argue that the fact that our moral beliefs are not tracking the moral truth also provides an undercutting and a higher-order defeater for those beliefs. As a result, I will conclude that the epistemic status of our moral beliefs is undermined because of these two kinds of defeaters. Secondly, in Part II of this thesis, I will turn my attention to the two strongest objections to the EDA – the Conceptual Truth Objection and the Third Factor Objection. I will first offer two responses to the Conceptual Truth Objection and, based on these two responses, I will argue that the Conceptual Truth Objection fails as a challenge to the EDA. I will then also argue that there currently doesn’t exist an acceptable version of the Third Factor Objection and it is also unlikely that such a version could be constructed in the future. I will finally conclude that both objections are problematic and they are thus unable to give us reason to doubt the EDA. (shrink)

This book is a defence of the philosophy of common sense in the spirit of Thomas Reid and G.E. Moore, drawing on the work of Aristotle, evolutionary biology and psychology, and historical studies on the origins of early modern philosophy. It defines and explores common sense beliefs, and defends them from challenges from prominent philosophers.

This thesis explores the use of the concept 'realization' in the philosophy of mind. The primary focus is on the role realization plays in assessing or opposing identity theory. The history of the use of the concept of realization in the philosophy of mind is reviewed, and from that a set of desiderata to be used for assessing accounts of realization is extracted. The desiderata are applied to a sample account of realization proposed by Sydney Shoemaker. (2007) Next the application (...) of 'realization' in contemporary contexts is considered, focusing on the idea that mental kinds are, potentially, multiply realized. Based on interpretations of results from research in the relevant sciences this thesis considers two kinds of strategies used to object to multiple realization, (1) arguments against the concept of multiple realization: the Grain Argument (Bechtel and Mundale 1999), and Shapiro's Dilemma (Shapiro 2000), and (2) defeaters for alleged cases/examples of multiple realization proposed by Lawrence Shapiro and Thomas Polger: unification, individual differences, kind splitting, and abstraction and idealization. (Polger and Shapiro 2016) The thesis argues that, ultimately, these arguments hinge on the claim that there is no empirical evidence of multiply realized mental kinds. In response to this claim, the fourth chapter presents novel examples of multiple realization drawn from research in the cognitive neuroscience of language. There are three aspects from the study of language that are presented as examples of multiple realization: (1) language lateralization, (2) reading acquisition, and (3) second/multi- language learning. The analysis of these case studies applies Shoemaker's account of realization as a framework for describing the empirical data as cases of multiple realization. Objections to, and defeaters for, these cases are considered and rejected. The thesis concludes by raising the possibility that mental kinds are realized by mechanisms. This proposal involves drawing connections between traditional questions/views from the philosophy of mind with a current research program from the philosophy of science; the view is particularly important in the philosophy of neuroscience and the philosophy of biology, known as 'new mechanism'.

Meinertsen has recently put forward three arguments against disjunctive properties: the arguments from truthmaking, commonality, and causation. In this paper, I argue that all three arguments fail. The argument from truthmaking rests on the problematic notion of different types of truthmakers and is therefore itself problematic. The argument from commonality may hold but only at the cost of losing much of the philosophical significance of its conclusion. The argument from causation essentially collapses into the argument from truthmaking and is therefore (...) problematic for the same reason as the latter is. I conclude that Meinertsen has not made a case against disjunctive properties. (shrink)

In Unbelievable Errors, I defend an error theory about all normative judgements, I argue that we cannot believe this theory, and I argue that our inability to believe this theory makes the theory more likely to be true. This précis gives a brief overview of my arguments for the error theory and of my explanation of our inability to believe the theory.

Sally Haslanger is concerned with the debate between social constructionists and error theorists about a given category, such as race or gender. For example, social constructionists about race claim that the term “race” refers to a social kind, whereas error theorists claim that the term “race” is an empty term, that is, nothing belongs to this category. It seems that this debate depends in part on the meaning of the corresponding expression, and this, according to some theorists, depends in turn (...) on our intuitions as competent speakers. But then, what should we say if competent users of the expressions “race” and “gender” understand the terms so that being a natural or biological property is a necessary condition in order to fall under the term? If that were the case, then it would seem that a social constructionist view would be out of the question. Haslanger has argued that a social constructionist view could still be defended in that situation. In order to argue for this, she draws on the classical arguments for semantic externalism, which show that the intuitions of competent speakers concerning the nature of a given category, and the objective type that actually unifies the instances of that category, may come apart. In this paper I will argue that the arguments for semantic externalism concerning natural kinds do not really offer support for Haslanger’s claim that ordinary intuitions concerning social kinds are not relevant.

How is metaphysics related to the empirical sciences? Should metaphysics in general be guided by the sources, methods and results of the sciences? And what about the special case of the metaphysics of the social world: should it likewise be guided by the sources, methods and results of the social sciences? In her paper “Social Science as a Guide to Social Metaphysics?”, K. Hawley raises the question: If we are sympathetic to the project of naturalising metaphysics, how should we approach (...) the metaphysics of the social world? She proceeds by discussing three approaches to social metaphysics: inference to the best explanation from current social science, descriptive conceptual analysis, and normative, especially ‘ameliorative’ projects. At the end of her discussion, she reaches a rather pessimistic conclusion, especially as regards the IBE approach: “a number of phenomena indicate that the prospects for securely basing social metaphysics via inference to the best explanation from social science are currently faint. […] We need to look elsewhere if we are to develop a metaphysics of the social world.” In my comments on her paper, I try to re-animate the program of an inductive metaphysics by defending the idea that the method of inference to the best explanation should be the central method of justification for metaphysics in general and for social metaphysics in particular.

1. Categories and the Scientific Turn of Metaphysics: The Notion of World-Fundamentality What are the fundamental inhabitants of the world? This question, as old as it is new, is about the fundamental structure of our world. Is our world a world of Aristotle's ordinary substances, Locke's physical substances, Husserl's wholes, Wittgenstein's facts, Sellars's processes, or Quine's sets? In order to distinguish the sort of metaphysical fundamentality at stake in this discussion from other possible types of fundamentality, I shall call it (...) from now on "world-fundamentality." In this article I want to make a proposal in the context of this metaphysical dispute. The proposal is the addition of a new criterion of world-fundamentality to the existing catalog of independence and simplicity, among some other prominent classical examples. I call this criterion "the materialist criterion of world-fundamentality" because it states that metaphysicians should not decide the question of whether our world is a world of facts rather than a world of sets or other categories without considering the explanatory power of such categories to account for the relation between "the manifest image" and "the scientific image," to use the words of Wilfrid Sellars.

Graham Priest has brilliantly analyzed Hegel's dialectics, as far as its logical and abstract ontological (metaphysical) structure goes, and has successfully related it to his own logically sophisticated dialethism. After briefly reminding the reader of his account, the paper turns to the other, not purely logical side of Hegel's dialectics, and points to his strategy of bringing together ontological, anthropological and historical matters together with the logical structure, in a manner quite foreign to analytic tradition. It concludes with the proposal (...) that Hegel's way of directly connecting logical ontological, anthropological and historical matters has played the crucial role in the birth of what later became known as specifically ``continental'' philosophy. The paper concludes by raising the question of the relation between the two, the abstract logico-ontological approach, favored by Priest, and the rich, anthropologically and historically informed one found in all major works of Hegel.

I first argue that there are many true claims of the form: Φ-ing would be morally required, if anything is. I then explain why the following conditional-type is true: If φ-ing would be morally required, if anything is, then anything is actually morally required. These results allow us to construct valid proofs for the existence of some substantive moral facts—proofs that some particular acts really are morally required. Most importantly, none of my argumentation presupposes any substantive moral claim; I use (...) only plausible claims that most moral skeptics and error theorists can and do accept. The final section diagnoses why my arguments work. Here, I offer an explanation for the supervenience of the moral on the non-moral that may help those worried that the strategy is a sophisticated trick. I conclude by considering two objections. In replying to these objections, I explain why the strategy may allow us to demonstrate more than “obvious” moral truths, and why it may also address a stronger version of error theory, according to which, moral truths are not possible.

Richard Hare argues that the fundamental assumptions of Kant's ethical system should have led Kant to utilitarianism, had Kant not confused a norm's generality with its universality, and hence adopted rigorist, deontological norms. Several authors, including Jens Timmermann, have argued contra Hare that the gap between Kantian and utilitarian/consequentialist ethics is fundamental and cannot be bridged. This article shows that Timmermann's claims rely on a systematic failure to separate normative and metaethical aspects of each view, and that Hare's attempt to (...) bridge the gap between Kantian and consequentialist ethics is immune to Timmermann's criticisms. Furthermore, the term “Kantian ethics” is often misleading, and should typically be qualified as either “Kantian rationalism” or “Kantian deontology” in order to avoid confusions of the sort Timmermann falls into.

In a recent issue of this journal, Jorn Sonderholm presents two main criticisms of my 2008 case for a diachronic view of base property exemplification in metaethics. This essay contends that neither of Sonderholm’s criticisms hit their mark, and that there are additional reasons to adopt a diachronic view of base property exemplification. Thus, the case for a diachronic view of base property exemplification in metaethics is stronger than previously thought.

Revelation is the thesis that having an experience that instantiates some phenomenal property puts us in a position to know the nature or essence of that property. It is widely held that although Revelation is prima facie plausible, it is inconsistent with physicalism, and, in particular, with the claim that phenomenal properties are physical properties. I outline the standard argument for the incompatibility of Revelation and physicalism and compare it with the Knowledge Argument. By doing so, I hope to show (...) that on various plausible interpretations of Revelation it is in fact consistent with physicalism. Moreover, there is a robust reading of Revelation that a posteriori physicalists can, and should, accept. (shrink)

This article argues for two related theses. First, it defends a general thesis: any kind of necessity, including metaphysical necessity, can only be known a priori. Second, however, it also argues that the sort of a priori involved in modal metaphysical knowledge is not related to imagination or any sort of so-called epistemic possibility. Imagination is neither a proof of possibility nor a limit to necessity. Rather, modal metaphysical knowledge is built on intuition of philosophical categories and the structures they (...) form.

There is a growing consensus among philosophers of science that scientific endeavors of understanding the human mind or the brain exhibit explanatory pluralism. Relatedly, several philosophers have in recent years defended an interventionist approach to causation that leads to a kind of causal pluralism. In this paper, I explore the consequences of these recent developments in philosophy of science for some of the central debates in philosophy of mind. First, I argue that if we adopt explanatory pluralism and the interventionist (...) approach to causation, our understanding of physicalism has to change, and this leads to what I call pluralistic physicalism. Secondly, I show that this pluralistic physicalism is not endangered by the causal exclusion argument. (shrink)

When I open my eyes and look at a Rubik’s cube, there is something it is like for me visually in looking at it. Various color qualities are presented to me, and they are arranged in a specific pattern. By having an experience with this particular phenomenal character I am also thereby visually representing the world outside my experience as being a certain way. If I experience a blue square to the left of a red square, the world outside my (...) experience is represented as being one way. As I turn the cube, and come to view a green square to the left of another green square, I have an experience with a different phenomenal character. But I also come to represent the world differently. In virtue of the difference in phenomenology there is a corresponding difference in how the world is represented as being. Moreover, it seems that any two experiences with the same phenomenal character will share a certain sort of intentional content.1 If two subjects have phenomenally identical experiences, there is an important sense in which the way the world appears to them is precisely the same. I will call this intentional content that supervenes on phenomenal character “phenomenal content”. But how are we to understand this notion of “ways of appearing”? Most philosophers who have acknowledged the existence of phenomenal content have held that the way something appears to a subject is simply a matter of the properties.. (shrink)

The so-called Canberra Plan is a grandchild of the Ramsey-Carnap treatment of theoretical terms. In its original form, the Ramsey-Carnap approach provided a method for analysing the meaning of scientific terms, such as “electron”, “gene” and “quark”—terms whose meanings could plausibly be delineated by their roles within scientific theories. But in the hands of David Lewis (1970, 1972), the original approach begat a more ambitious descendant, generalised and extended in two distinct ways: first, Lewis applied the technique to analyse the (...) meaning of terms introduced not just by explicit scientific theories, but also by implicit folk theories such as folk psychology; second, he supplemented the theory to provide an account of the way in which the referents of the analysed terms might be identified on the basis of empirical investigation.
