This paper tries to do three things. First, it tries to make it plausible that correct rules of reasoning do not always preserve justification: in other words, if you begin with a justified attitude, and reason correctly from that premise, it can nevertheless happen that you’ll nevertheless arrive at an unjustified attitude. Attempts to show that such cases in fact involve following an incorrect rule of reasoning cannot be vindicated. Second, it also argues that correct rules of reasoning do not even correspond to permissions of “structural rationality”: it is not always structurally permissible to base an attitude on other attitudes from which it follows by correct reasoning. Third, from these observations it tries to build a somewhat positive account of the correctness of rules of reasoning as a more sui generis notion irreducible to either justification or structural rationality. This account vindicates an important unity of theoretical and practical reasoning as well as a qualified version of the thesis that deductive logic supplies correct rules of reasoning.

I argue, contrary to the consensus of most contemporary work in ethics, that there are no (fundamentally, distinctively) prudential reasons for action. That is to say: there is no class of reasons for action that is distinctively and fundamentally about the promotion of the agent’s own well-being. Considerations to do with the agent’s well-being can supply the agent with reasons only in virtue of her well-being mattering morally or in virtue of her caring about her own well-being. In both of these cases, the way that such prudential considerations supply reasons for action is a way that the well-being of others can supply reasons for action too.

A slew of recent political theorists—many taking their cue from the political writings of Bernard Williams—have recently contended that political normativity is its own kind of normativity, distinct from moral normativity. In this article, we first attempt to clarify what this claim amounts to and then reconstruct and interrogate five major arguments for it. We contend that all these arguments are unconvincing and fail to establish a sense in which political normativity is genuinely separate from morality.

Recent work on rationality has been increasingly attentive to “coherence requirements”, with heated debates about both the content of such requirements and their normative status (e.g., whether there is necessarily reason to comply with them). Yet there is little to no work on the metanormative status of coherence requirements. Metaphysically: what is it for two or more mental states to be jointly incoherent, such that they are banned by a coherence requirement? In virtue of what are some putative requirements genuine and others not? Epistemologically: how are we to know which of the requirements are genuine and which aren’t? This paper tries to offer an account that answers these questions. On my account, the incoherence of a set of attitudinal mental states is a matter of its being (partially) constitutive of the mental states in question that, for any agent that holds these attitudes jointly, the agent is disposed, when conditions of full transparency are met, to give up at least one of the attitudes.

Despite increasing prominence, ‘ought’-contextualism is regarded with suspicion by most metaethicists. As I’ll argue, however, contextualism is a very weak claim, that every metaethicist can sign up to. The real controversy concerns how contextualism is developed. I then draw an oft-overlooked distinction between “parochial” contextualism—on which the contextually-relevant standards are those that the speaker, or others in her environment, subscribe to—and “aspirational” contextualism—on which the contextually-relevant standards are the objective standards for the relevant domain. However, I argue that neither view is acceptable. I suggest an original compromise: “ecumenical contextualism”, on which some uses of ‘ought’ are parochial, others aspirational. Ecumenical contextualism is compatible with realism or antirealism, but either combination yields interesting results. And though it’s a cognitivist view, it is strengthened by incorporating an expressivist insight: for robustly normative usages of ‘ought’, the contextually-relevant standards must be endorsed by the speaker.

Going about our daily lives in an orderly manner requires us, once we are aware of them, to dismiss many metaphysical possibilities. We take it for granted that we are not brains in vats, or living in the Matrix, or in an extended dream. Call these things that we take for granted “anti-skeptical assumptions”. What should a reflective agent who believes these things think of these beliefs? For various reasons, it can seem that we do not have evidence for such anti-skeptical assumptions. Are anti-skeptical assumptions, then, beliefs that one may rationally hold without evidence for them – indeed, even in the face of a positive judgment that one lacks evidence for them? I survey and criticize some prominent answers to this question, and then offer a positive view that blends externalism about evidence with a mild, qualified kind of pragmatism. The view I offer aims to do justice to the sense that anti-skeptical assumptions are evidentially groundless while also maintaining that one cannot rationally believe something that one judges oneself to lack sufficient evidence for.

In discussions of whether and how pragmatic considerations can make a difference to what one ought to believe, two sets of cases feature. The first set, which dominates the debate about pragmatic reasons for belief, is exemplified by cases of being financially bribed to believe (or withhold from believing) something. The second set, which dominates the debate about pragmatic encroachment on epistemic justification, is exemplified by cases where acting on a belief rashly risks some disastrous outcome if the belief turns out to be false. Call those who think that pragmatic considerations make a difference to what one ought to believe in the second kind of case, but not in the first, ‘moderate pragmatists’. Many philosophers – in particular, most advocates of pragmatic and moral encroachment – are moderate pragmatists. But moderate pragmatists owe us an explanation of exactly why the second kind of pragmatic consideration makes a difference, but the first kind doesn’t. I argue that the most promising of these explanations all fail: they are either theoretically undermotivated, or get key cases wrong, or both. Moderate pragmatism may be an unstable stopping point between a more extreme pragmatism, on one hand, and an uncompromising anti-pragmatism on the other.

Thinking Through the Body: Essays in Somaesthetics (TTB) is a collection of essays developing further the project of somaesthetics that the author has defended in other writings. Most of the essays have been published elsewhere and revised for this presentation. There are two objectives pursued throughout the essays. One is that of delineating the nature of somaesthetics so that its scope becomes clearer, and the other is that of defending the discipline against its critics.What is somaesthetics? Somaesthetics is offered as a branch of aesthetics whose interdisciplinary nature attempts to reshape primarily aesthetics and philosophy, while it has application in a variety of educational, artistic, technological, etc., contexts. Its primary target is the neglect of the body’s importance in aesthetics and in philosophy in general. According to this view, aesthetics has ignored the body’s aesthetic significance for the sake of other projects such as the definition of art. In opposition to t ..

: Phenomenal knowledge usually comes from experience. But it need not. For example, one could know what it’s like to see red without seeing red—indeed, without having any color experiences. Daniel Dennett (2007) and Pete Mandik (forthcoming) argue that this and related considerations undermine the knowledge argument against physicalism. If they are right, then this is not only a problem for anti‐physicalists. Their argument threatens to undermine any version of phenomenal realism— the view that there are phenomenal properties, or qualia, that are not conceptually reducible to physical or functional properties. I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. This will strengthen the case for physically and functionally irreducible qualia. 2 Phenomenal knowledge usually comes from experience. For example, I know what it’s like to see red because I have done so. Does knowing what it’s like to have an experience with phenomenal character X require having an experience with X? No. A famous counterexample is Hume’s missing shade of blue, in which one can extrapolate from phenomenally similar experiences (A Treatise of Human Nature, Bk. I, Pt. I, Sec. I).1 One might think that a weaker version of the no‐phenomenal‐knowledge‐without‐experience thesis remains tenable, e.g., that knowing what it’s like to see in color requires having or having had color experiences. But this thesis also seems doubtful. Peter Unger (1966) devised plausible counterexamples over four decades ago, and since then others (e.g., Lewis 1988, Alter 1998, Stoljar 2005) have done the same. One could have phenomenal knowledge of color experiences without having such experiences. Indeed, one could have such knowledge without having experiences that are remotely like color experiences. What is the significance of this observation for contemporary debates about consciousness and physicalism? Daniel Dennett (2007) and Pete Mandik (forthcoming) suggest that it undermines the knowledge argument against physicalism.2 That is because they take the claim that someone who has never seen in color could not know what it’s like to see in color to be the basis of the knowledge argument’s main epistemic premise: the premise that (roughly put) 3 no amount of physical knowledge is sufficient for phenomenal knowledge of color experiences. If they are right, then this is not only a problem for anti‐ physicalists. Many physicalists (e.g., Loar 1990/97, Papineau 2002, 2007) accept the knowledge argument’s epistemic premise. Dennett’s and Mandik’s arguments threaten all versions of what David Chalmers (2003) calls phenomenal realism, the view that there are phenomenal properties, or qualia, that are not conceptually reducible to physical or functional properties.3 I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. The net result will be to strengthen the case for physically inexplicable qualia.

In this paper I argue that a priori arguments fail to present any real problem for physicalism. They beg the question against physicalism in the sense that the argument will only seem compelling if one is already assuming that qualitative properties are nonphysical. To show this I will present the reverse-zombie and reverse-knowledge arguments. The only evidence against physicalism is a priori arguments, but there are also a priori arguments against dualism of exactly the same variety. Each of these parity arguments has premises that are just as intuitively plausible, and it cannot be the case that both the traditional scenarios and the reverse-scenarios are all ideally conceivable. Given this one set must be merely prima facie conceivable and only empirical methods will tell us which is which. So, by the time a priori methodology will be of any use it will be too late.

The Knowledge Argument is misconstructed. Knowing that it is ‘just obvious’ that Mary will learn something new on leaving her black and white room, we nevertheless assume she can acquire a complete knowledge of the physical inside it – thereby predetermining the outcome of the thought experiment in favour of a refutation of physicalism. If we reformulate the argument to leave the question of what she can learn in the room open, it becomes clear, not only that physicalism can survive the Knowledge Argument, but also that there is only one perspective on the relationship between qualia and the physical that will permit it to do so. If physicalism is true, this perspective must be the correct view of the qualia-physical relationship – the solution to the mind-body problem, a conclusion supported by its ability to resolve a number of associated difficulties, including Kripke’s problem for proposed identities and Chalmers’ Hard Problem

Online personalized genetic testing services offer accessible and convenient options for satisfying personal curiosity about health and obtaining answers about one’s genetic provenance. They are especially attractive to healthy people who wish to learn about their future risk of disease, as Paul Mason’s case study of “Jordan” illustrates. In this response, we consider how online genetic testing services are used by people diagnosed with a common neurodegenerative disease, Parkinson’s disease, to gain a sense of certainty regarding the future.

Deep brain stimulation (DBS) is an effective treatment for the debilitating motor symptoms of Parkinson’s disease and other neurological disorders. However, clinicians and commentators have noted that DBS recipients have not necessarily experienced the improvements in quality of life that would be expected, due in large part to what have been described as the ‘psychosocial’ impacts of DBS. The premise of this paper is that, in order to realise the full potential of DBS and similar interventions, clinical services need to be arranged in such a way that these psychosocial dimensions are recognised and managed. Our starting point is that the psychosocial effects of DBS ‘in the field’ present us with analytically-useful disruptions: they disturb and foreground deeply held assumptions relating to the individual, health and its treatment, and which in a crude form manifest as the myth of technological solutionism within health care. Drawing on scholarship in medical sociology and science and technology studies (STS), we argue that DBS brings to the fore the relational dimensions of personhood, and demonstrates the emotional and social turmoil that can result if the relational dimensions of personhood are ignored by clinical services. In light of this, we argue that DBS should be implemented within a regime of care. Drawing on ethnographic research of a paediatric DBS clinical service, we provide an example of a regime of care, and conclude by reflecting on what other DBS services might learn from this paediatric service.

The relevance of analytic metaphysics has come under criticism: Ladyman & Ross, for instance, have suggested do discontinue the field. French & McKenzie have argued in defense of analytic metaphysics that it develops tools that could turn out to be useful for philosophy of physics. In this article, we show first that this heuristic defense of metaphysics can be extended to the scientific field of applied ontology, which uses constructs from analytic metaphysics. Second, we elaborate on a parallel by French & McKenzie between mathematics and metaphysics to show that the whole field of analytic metaphysics, being useful not only for philosophy but also for science, should continue to exist as a largely autonomous field.

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

Traditionally, Physics has been dominated by the image of objects, that is, by the atomistic metaphysics of absolutely intrinsic (monadic) properties of qualitatively unchangeable individual entities. The first major challenge to this metaphysics inside physics comes with quantum mechanics, specifically with the well-known phenomenon known as ‘quantum entanglement’. From quantum entanglement it seems that we can conclude that: (1) quantum objects are not independent entities; (2) wholes (systems) have an ontological priority over their parts (subsystems). However, it is arguable that is too risky to infer such conclusions directly from quantum mechanics. If epistemological consequences of quantum mechanics are inescapable, is seems unwise to take any direct ontological consequences from it. After all, quantum mechanics does not refer to the states of physical entities before measurements, but it is just a theory that allows us to calculate the possible outcomes from any given measurement. Still, this does not mean that, indirectly, quantum mechanics does not give some account of quantum reality that deeply challenges traditional objects metaphysics, namely, (1) through the simple existence of the measurement problem; and (2) through the experimental violations of Bell inequality. Even challenged, the object picture in physics can thus prevail. But we must also not forget that on the last decades, Quantum Physics has being evolved beyond the direct scope of quantum mechanics. I will try to argue that in at least some contemporary approaches in Quantum Physics we can see that there is a movement pointing towards a relational ontological view, according to which the ontological primacy is not to be given to individual entities, as self-sufficient elements with their own intrinsic and immutable identities—as in traditional object’s metaphysics—but to some sort of relational structures. I argue that although this relational metaphysics is still to be developed, it will have to be able to account for both the relational and object natures of quantum entities.

Metaphysics is sensitive to the conceptual tools we choose to articulate metaphysical problems. Those tools are a lens through which we view metaphysical problems; the same problems look different when we change the lens. There has recently been a shift to "postmodal" conceptual tools: concepts of ground, essence, and fundamentality. This shift transforms the debate over structuralism in the metaphysics of science and philosophy of mathematics. Structuralist theses say that patterns are "prior" to the nodes in the patterns. In modal terms this would mean that the nodes cannot vary independently of the pattern. But its postmodal meaning is unclear. Does it mean, e.g., that a fundamental account of reality somehow speaks only of patterns? What would that mean? Three structuralist positions are examined through a postmodal lens: nomic/causal/dispositional essentialism, structuralism about individuals (e.g., structural realism, e.g., ante rem mathematical structuralism), comparativism about quantities. The question of when theories are equivalent, and how that impacts the debate over structuralism, is also discussed.
