David Friedman posed a number of libertarian philosophical problems (Friedman 1989). This essay criticizes Walter Block’s Rothbardian responses (Block 2011) and compares them with J C Lester’s critical-rationalist, libertarian-theory responses (Lester [2000] 2012). The main issues are as follows. 1. Critical rationalism and how it applies to libertarianism. 2.1. How libertarianism is not inherently about law and is inherently about morals. 2.2. How liberty relates to property and can be maximized: carbon dioxide and radio waves. 2.3. Applying (...) the theory to flashlights. 2.4. Applying the theory to the probability of imposed risks. 2.5. “Homesteading” or initial acquisition. 2.6 What is “essential” for a “true libertarian.” 2.7. Crime and punishment. 2.8. Extent of punishment. 2.9. The libertarian response to a madman with a gun. 2.10. How contradictions in rights are possible. 2.11. The draft. 3.1. Utilitarian libertarianism and “nose counting”. 3.2. How interpersonal comparisons of utility are possible and utility monsters are not a threat. 3.3. Why it is not utilitarian in practice to kill an innocent prisoner to prevent a riot. 3.4. Why David Friedman should not be forced to give up one of his eyes. 3.5. How utilitarians can be libertarians. Conclusion: a proper theory of liberty combined with critical rationalism offers superior solutions to Friedman’s problems. Appendix: replies to two commentators. (shrink)

Lester‘s reply to the review by Gordon and Modugno of Escape from Leviathan was due to appear in a later edition of the same periodical, but it was eventually dropped without notice or a reason being given. Subsequently, their review has occasionally been cited in isolation as a refutation of that book‘s theory of liberty, the compatibility of such liberty with welfare maximisation, and the use of "Popperian views" as though a complete reply did not exist and were not (...) freely available and easily found online. To make it harder to avoid the reply, whether by accident or design, it is reproduced here (but with sundry small emendations for greater clarity). (shrink)

This book has many arguments doing an excellent job of dismantling the positions of those who would have the state do considerably more than defend the national realm. Thus far, it is hard for me to fault it—which is more difficult when one is already in agreement: the ideologically opposed can often provide more useful criticisms. But, as the book‟s title indicates, it does not go all the way to anarcho-liberalism (in fact, it does not even fully embody certain basic (...) tenets of classical liberalism). And as its criticisms of anarcho-liberalism—or private-property anarchy—are those to which I am ideologically opposed, I shall mainly concentrate on those. (shrink)

Charles Murray describes himself as a libertarian, most notably in his short book, What it Means to be a Libertarian. He might more accurately have described himself as having libertarian tendencies. My reading of Simple Justice is that the views it espouses are far more traditionalist than libertarian. Neither traditionalist state-retribution nor modernist state-leniency is libertarian. Nor does either provide as just or efficient a response to crime as does libertarian restitution, including restitutive retribution. Here, I shall respond directly only (...) to Murray's views, rather than also deal with state-leniency. This is because I accept Murray's thesis, without endorsing his specific arguments for it, that state-leniency is disastrous as a response to crimes against persons and their justly acquired property.

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a (...) priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality. This major work by a leading philosopher will appeal to philosophers in all areas. This entry contains uncorrected proofs of front matter, chapter 1, and first excursus. (shrink)

What does it mean to know how to do something? This book develops a comprehensive account of know-how, a crucial epistemic goal for all who care about getting things right, not only with respect to the facts, but also with respect to practice. It proposes a novel interpretation of the seminal work of Gilbert Ryle, according to which know-how is a competence, a complex ability to do well in an activity in virtue of guidance by an understanding of what it (...) takes to do so. This idea is developed into a full-fledged account, Rylean responsibilism, which understands know-how in terms of the normative guidance and responsible control of one's acts. Within the complex current debate about know-how, this view occupies a middle ground position between the intellectualist claim that know-how just is propositional or objectual knowledge and the anti-intellectualist claim that know-how just is ability. In genuine know-how, practical ability and guiding intellect are both necessary, but essentially intertwined. (shrink)

Two separate research programs have revealed two different factors that feature in our judgments of whether some entity persists. One program—inspired by Knobe—has found that normative considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when the changes it undergoes lead to improvements. The other program—inspired by Kelemen—has found that teleological considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when it preserves its purpose. Our goal (...) in this paper is to determine what causes persistence judgments. Across four studies, we pit normative considerations against teleological considerations. And using causal modeling procedures, we find a consistent, robust pattern with teleological and not normative considerations directly causing persistence judgments. Our findings put teleology in the driver’s seat, while at the same time shedding further light on our folk notion of an object. (shrink)

This essay attempts to provide and defend what may be the first actual argument in support of P. F. Strawson's merely stated vision of a response-dependent theory of moral responsibility. It does so by way of an extended analogy with the funny. In part 1, it makes the easier and less controversial case for response-dependence about the funny. In part 2, it shows the tight analogy between anger and amusement in developing the harder and more controversial case for response-dependence about (...) a kind of blameworthiness. It then defends the view from three serious skeptical challenges. (shrink)

A growing literature is premised on the claim that quantum mechanics provides evidence for metaphysical indeterminacy. But does it? None of the currently fashionable realist interpretations involve fundamental indeterminacy and the ‘standard interpretation’, to the extent that it can be made out, doesn't require indeterminacy either.

Using as a starting point recent and apparently incompatible conclusions by Saunders and Knox, I revisit the question of the correct spacetime setting for Newtonian physics. I argue that understood correctly, these two versions of Newtonian physics make the same claims both about the background geometry required to define the theory, and about the inertial structure of the theory. In doing so I illustrate and explore in detail the view—espoused by Knox, and also by Brown —that inertial structure is defined (...) by the dynamics governing subsystems of a larger system. This clarifies some interesting features of Newtonian physics, notably the distinction between using the theory to model subsystems of a larger whole and using it to model complete universes, and the scale-relativity of spacetime structure. _1_ Introduction _2_ Newtonian Mechanics and Galilean Spacetime _3_ Vector Relationism and Maxwellian Spacetime _4_ Recovering the Galilei Group: Dynamics of Subsystems _5_ Knox on Inertial Structure _6_ Connections on Maxwellian Spacetime _7_ Knox on Newtonian Gravity _8_ Vector Relationism and Newton–Cartan Theory _9_ Inertial Structure in Newton–Cartan Gravity _10_ Reconciling Knox and Saunders _11_ Conclusions.

Many philosophers embrace grounding, supposedly a central notion of metaphysics. Grounding is widely assumed to be irreflexive, but recently a number of authors have questioned this assumption: according to them, it is at least possible that some facts ground themselves. The primary purpose of this paper is to problematize the notion of self-grounding through the theoretical roles usually assigned to grounding. The literature typically characterizes grounding as at least playing two central theoretical roles: a structuring role and an explanatory role. (...) Once we carefully spell out what playing these roles includes, however, we find that any notion of grounding that isn’t irreflexive fails to play these roles when they are interpreted narrowly, and is redundant for playing them when they are interpreted more broadly. The upshot is that no useful notion of grounding can allow a fact to ground itself. (shrink)

This article uses the case study of ethnobiological classification to develop a positive and a negative thesis about the state of natural kind debates. On the one hand, I argue that current accounts of natural kinds can be integrated in a multidimensional framework that advances understanding of classificatory practices in ethnobiology. On the other hand, I argue that such a multidimensional framework does not leave any substantial work for the notion “natural kind” and that attempts to formulate a general account (...) of naturalness have become an obstacle to understanding classificatory practices.

I argue that according to Socrates in the Phaedo we should not merely evaluate bodily pleasures and desires as worthless or bad, but actively avoid them. We need to avoid them because they change our values and make us believe falsehoods. This change in values and acceptance of falsehoods undermines the soul’s proper activity, making virtue and happiness impossible for us. I situate this account of why we should avoid bodily pleasures within Plato’s project in the Phaedo of providing Pythagorean (...) and Orphic ideas with clearer meanings and better justifications.

An introduction to our edited volume, The Metaphysics of Relations, covering a range of issues including the problem of order, the ontological status of relations, reasons for ancient scepticism about relational properties, and two ways of drawing the distinction between internal and external relations.

Supervenience is necessary co-variation between two sets of entities. In the good old days, supervenience was considered a useful philosophical tool with a wide range of applications in the philosophy of mind, metaethics, epistemology, and elsewhere. In recent years, however, supervenience has fallen out of favor, giving place to grounding, realization, and other, more metaphysically “meaty”, notions. The emerging consensus is that there are principled reasons for which explanatory theses cannot be captured in terms of supervenience, or as the slogan (...) goes: “Supervenience Is Nonexplanatory”. While SIN is widely endorsed, it is far from clear what it amounts to and why we should believe it. In this paper, I will distinguish various theses that could be meant by it, and will argue that none of them is both interesting and plausible: on some interpretations of ‘explanatory’, we have no reason to believe that supervenience is unexplanatory, while on other interpretations, supervenience is indeed unexplanatory, but widely accepted textbook cases of explanatory relations come out as unexplanatory, too. This result raises doubts as to whether there is any interesting sense in which SIN is true, and suggests that the contemporary consensus about supervenience is mistaken. (shrink)

Many philosophers have claimed that the folk endorse moral universalism. Some have taken the folk view to support moral universalism; others have taken the folk view to reflect a deep confusion. And while some empirical evidence supports the claim that the folk endorse moral universalism, this work has uncovered intra-domain differences in folk judgments of moral universalism. In light of all this, our question is: why do the folk endorse moral universalism? Our hypothesis is that folk judgments of moral universalism (...) are generated in part by a desire to punish. We present evidence supporting this across three studies. On the basis of this, we argue for a debunking explanation of folk judgments of moral universalism. Our results not only further our understanding of the psychological processes underpinning folk judgments of moral universalism. They also bear on philosophical discussions of folk meta-ethics.

The sensorimotor theory of perceptual experience claims that perception is constituted by bodily interaction with the environment, drawing on practical knowledge of the systematic ways that sensory inputs are disposed to change as a result of movement. Despite the theory’s associations with enactivism, it is sometimes claimed that the appeal to ‘knowledge’ means that the theory is committed to giving an essential theoretical role to internal representation, and therefore to a form of orthodox cognitive science. This paper defends the role (...) ascribed to knowledge by the theory, but argues that this knowledge can and should be identified with bodily skill rather than representation. Making the further argument that the notion of ‘representation hunger’ can be replaced with ‘prima facie representation hunger’, it concludes that although the theory could optionally be developed scientifically in part by reference to internal representation, it makes a strong and natural fit with anti-representationalist embodied or enactive cognitive science.

I explain a tension between musical creationism (the view that musical works are abstract artifacts) and the view that there is no vague existence. I then suggest ways to reconcile these views. My central conclusion is that, although some versions of musical creationism imply vague existence, others do not. I discuss versions of musical creationism held by Jerrold Levinson, Simon Evnine, and Kit Fine. I also present two new versions. I close by considering whether the tension is merely an instance (...) of a general problem raised by artifacts, both abstract and concrete. I argue that on at least one defensible account of music the tension is especially problematic for abstracta. I focus on musical works, but much of the paper straightforwardly applies to other kinds of abstract artifacts. (shrink)

When an entity ontologically depends on another entity, the former ‘presupposes’ or ‘requires’ the latter in some metaphysical sense. This paper defends a novel view, Dependence Deflationism, according to which ontological dependence is what I call an aggregative cluster concept: a concept which can be understood, but not fully analysed, as a ‘weighted total’ of constructive and modal relations. The view has several benefits: it accounts for clear cases of ontological dependence as well as the source of disagreement in controversial (...) ones; it gives a nice story about the evidential relevance of modal, mereological and set-theoretic facts to ontological dependence; and it makes sense of debates over the relation's formal properties. One important upshot of the deflationary account is that questions of ontological dependence are generally less deep and less interesting than usually thought. (shrink)

Many people believe that for someone to now be responsible for some past action, the agent of that action and the responsible agent now must be one and the same person. In other words, many people that moral responsibility presupposes numerical personal identity. In this paper, I show why this platitude is false. I then suggest an account of what actual metaphysical relationship moral responsibility presupposes instead.

How should we punish criminal offenders? One prima facie attractive punishment is administering a mandatory neurointervention—interventions that exert a physical, chemical or biological effect on the brain in order to diminish the likelihood of some forms of criminal offending. While testosterone-lowering drugs have long been used in European and US jurisdictions on sex offenders, it has been suggested that advances in neuroscience raise the possibility of treating a broader range of offenders in the future. Neurointerventions could be a cheaper, and (...) more effective method of punishment. They could also be more humane. Nevertheless, in this paper we provide an argument against the use of mandatory neurointerventions on offenders. We argue that neurointerventions inflict a significant harm on an offender that render them a morally objectionable form of punishment in a respect that incarceration is not. Namely, it constitutes an objectionable interference with the offender’s mental states. However, it might be thought that incarceration also involves an equally objectionable interference with the offender’s mental states. We show that even if it were the case that the offender is harmed to the same extent in the same respect, it does not follow that the harms are morally equivalent. We argue that if one holds that intended harm is more difficult to justify than harm that is unintended but merely foreseen, this means neurointerventions could be morally objectionable in a significant respect that incarceration is not.

We take it that we can exercise doxastic agency by reasoning and by making judgments. We take it, that is, that we can actively make up our minds by reasoning and judging. On what I call the ‘Standard View’ this is so because judgment can yield belief. It is typical to take it that judgments yield beliefs by causing them. But on the resultant understanding of the Standard View, I argue, it is unclear how judgment could play its role in (...) doxastic agency in the way we take it to. I therefore offer an alternative understanding of how judgment yields belief. Drawing on Ryle I argue that when one comes to believe by judging the event which is one's judging is token identical to the event which is one's coming to believe. This paves the way for version of the Standard View capable of explaining how we can actively make up our minds despite that we cannot believe or come to believe at will. (shrink)

eSports practice designates a unique set of activities tethered to competitive, virtual environments, or worlds. This correlation between eSports practitioner and virtual world, we argue, is inadequately accounted for solely in terms of something physical or intellectual. Instead, we favor a perspective on eSports practice to be analyzed as a perceptual and embodied phenomenon. In this article, we present the phenomenological approach and focus on the embodied sensations of eSports practitioners as they cope with and perceive within their virtual worlds. (...) By approaching eSports phenomenologically, we uncover ways in which its unique forms of virtual involvement overlap with as well as differentiate themselves from traditional structures of embodiment.

Is behavioral integration (i.e., which occurs when a subjects assertion that p matches her non-verbal behavior) a necessary feature of belief in folk psychology? Our data from nearly 6,000 people across twenty-six samples, spanning twenty-two countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we suggest that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely (...) asserts that p, non-linguistic behavioral evidence is disregarded. In light of this, we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

This paper presents a uniform general account of regress problems in the form of a pentalemma—i.e., a set of five mutually inconsistent claims. Specific regress problems can be analyzed as instances of such a general schema, and this Regress Pentalemma Schema can be employed to generate deductively valid arguments from the truth of a subset of four claims to the falsity of the fifth. Thus, a uniform account of the nature of regress problems allows for an improved understanding of specific (...) regress objections or arguments, and, correspondingly, of the general logical geography of the debate about infinite regresses. This uniform approach is illustrated by a treatment of the classical epistemological problem of justification, but it encompasses a whole variety of cases including explanation and ontological grounding. Furthermore, this general account is compared and contrasted with the existing literature discussing argument schemata for regress objections, particularly with the work of Jan Willem Wieland. It is shown how such other schemata can be incorporated and superseded by the general Regress Pentalemma Schema. (shrink)

This is a contribution to the symposium on Tim Scanlon’s Being Realistic about Reasons. We have two aims here: First, we ask for more details about Scanlon’s meta-metaphysical view, showing problems with salient clarifications. And second, we raise independent objections to the view – to its explanatory productivity, its distinctness, and the argumentative support it enjoys.

Many philosophers insist that the revisionary metaphysician—i.e., the metaphysician who offers a metaphysical theory which conflicts with folk intuitions—bears a special burden to explain why certain folk intuitions are mistaken. I show how evidence from cognitive science can help revisionist discharge this explanatory burden. Focusing on composition and persistence, I argue that empirical evidence indicates that the folk operate with a promiscuous teleomentalist view of composition and persistence. The folk view, I argue, deserves to be debunked. In this way, I (...) take myself to have illustrated one key role cognitive science can play in metaphysics; namely by helping the revisionary metaphysician discharge the explanatory burden of providing a plausible explanation of how the folk have gone wrong.

This chapter explores the relationship between ethical judgement writ large (as opposed to merely moral judgement) and motivation. We discuss arguments for and against views on which ethical judgement entails motivation, either alone or under conditions of rationality or normalcy, either at the individual or community level.

Here, I put forth a construal of P. F. Strawson’s so-called reversal, his view that what it means to be morally responsible is determined by our practices of holding responsible. The “concern-based” construal that I defend holds that what it means to be morally responsible is determined by the basic social concerns of which our practices are an expression. This construal, I argue, avoids a dilemma that Patrick Todd has recently raised for the reversal.

This paper examines the philosophical significance of the consequence relation defined in the $\Omega$-logic for set-theoretic languages. I argue that, as with second-order logic, the hyperintensional profile of validity in $\Omega$-Logic enables the property to be epistemically tractable. Because of the duality between coalgebras and algebras, Boolean-valued models of set theory can be interpreted as coalgebras. In Section \textbf{2}, I demonstrate how the hyperintensional profile of $\Omega$-logical validity can be countenanced within a coalgebraic logic. Finally, in Section \textbf{3}, the philosophical (...) significance of the characterization of the hyperintensional profile of $\Omega$-logical validity for the philosophy of mathematics is examined. I argue (i) that $\Omega$-logical validity is genuinely logical, and (ii) that it provides a hyperintensional account of formal grasp of the concept of `set'. Section \textbf{4} provides concluding remarks. (shrink)

In this paper I elicit a prediction from structural realism and compare it, not to a historical case, but to a contemporary scientific theory. If structural realism is correct, then we should expect physics to develop theories that fail to provide an ontology of the sort sought by traditional realists. If structure alone is responsible for instrumental success, we should expect surplus ontology to be eliminated. Quantum field theory (QFT) provides the framework for some of the best confirmed theories in (...) science, but debates over its ontology are vexed. Rather than taking a stand on these matters, the structural realist can embrace QFT as an example of just the kind of theory SR should lead us to expect. Yet, it is not clear that QFT meets the structuralist's positive expectation by providing a structure for the world. In particular, the problem of unitarily inequivalent representations threatens to undermine the possibility of QFT providing a unique structure for the world. In response to this problem, I suggest that the structuralist should endorse pluralism about structure. (shrink)

Reductive representationalism is the view that the qualitative properties associated with conscious experience are properties of the objects of the experience, and not of the experience itself. A prima facie problem for this view arises from dreams and hallucinations, in which qualitative properties are experienced but not instantiated in external objects of perception. I argue that representationalist attempts to solve it by appeal to actually uninstantiated properties are guilty of an absurdity akin to that which Ryle accused Descartes of in (...) the latter’s doctrine of immaterial substance.

In the 1990s, a debate raged across the whole postsocialist world as well as in Western development agencies such as the World Bank about the best approach to the transition from various forms of socialism or communism to a market economy and political democracy. One of the most hotly contested topics was the question of the workplace being organized based on workplace democracy (e.g., various forms of worker ownership) or based on the conventional employer-employee relationship. Well before 1989, many of (...) the socialist countries had started experimenting with various forms of "self-management" operating in more of a market setting, Yugoslavia being the most developed example. Thus one "path to the market" would .. (shrink)

Corruptionism is the view that following physical death, the human being ceases to exist but their soul persists in the afterlife. Survivalism holds that both the human being and their soul persist in the afterlife, as distinct entities, with the soul constituting the human. Each position has its defenders, most of whom appeal both to metaphysical considerations and to the authority of St Thomas Aquinas. Corruptionists claim that survivalism violates a basic principle of any plausible mereology, while survivalists tend to (...) reject the principle, though without as much detail as one would like. In this paper I examine both the key exegetical issues and the mereological question, arguing that Aquinas cannot be shown to have supported the principle in question, and that the principle should be rejected on independent grounds. If correct, some key planks in support of survivalism are established, with others to await further examination. (shrink)

The notion of an agent and the notion of a self are connected, for agency is one role played by the self. Millgram argues for a disunity thesis of agency on the basis of extreme incommensurability across some major life events. We propose a similar negative thesis about the self, that it is composed of relatively independent threads reflecting the different roles and different mind-sets of the person's life. Our understanding of those threads is based on theories of the narrative (...) construction of the self. Our disunity thesis is that there need be no overarching narrative that unifies those narrative threads. To explain how the threads hang together to produce coherent action, we make these positive claims: control normally switches smoothly and unconsciously between threads as circumstances require, within one thread there is likely to be acknowledgment of other threads, some situations require a temporary blending of threads, and some plans and policies reach across different threads and contribute to some coordination among them. Our account of a self provides an account of agency that has merits in comparison to Millgram's. Our narrative approach allows explanations of actions beyond rational deliberation. (shrink)

Cognitive categories in the geographic realm appear to manifest certain special features as contrasted with categories for objects at surveyable scales. We have argued that these features reflect specific ontological characteristics of geographic objects. This paper presents hypotheses as to the nature of the features mentioned, reviews previous empirical work on geographic categories, and presents the results of pilot experiments that used English-speaking subjects to test our hypotheses. Our experiments show geographic categories to be similar to their non-geographic counterparts in (...) the ways in which they generate instances of different relative frequencies at different levels. Other tests, however, provide preliminary evidence for the existence of important differences in subjects’ categorizations of geographic and non-geographic objects, and suggest further experimental work especially with regard to the role in cognitive categorization of different types of object-boundaries at different scales.

Williamson’s “anti-luminosity” argument aims to establish that there are no significant luminous conditions. “Far from forming a cognitive home”, luminous conditions are mere “curiosities”. Even supposing Williamson’s argument succeeds in showing that there are no significant luminous states his conclusion has not thereby been established. When it comes to determining what is luminous, mental events and processes are among the best candidates. It is events and processes, after all, which constitute the stream of consciousness. Judgment, for instance, is plausibly self-conscious. (...) If I am judging then plausibly I must know that I am. Similarly, deliberation is plausibly self-conscious. To be deliberating about some matter I plausibly must know that I am. That one is judging and that one is deliberating are thus plausibly luminous conditions. Furthermore, I argue, Williamson’s anti-luminosity argument fails to speak against this suggestion. This reveals that Williamson’s argument is more limited in scope than has been thought—something likely missed due to a misplaced focus on mental states in the luminosity debate as well as in epistemology and the philosophy of mind more generally. For all Williamson shows, there may be luminous events and processes of a sort apt to constitute a cognitive home. I conclude by considering how the anti-luminosity argument might be reinstated in the judgment case and argue that the natural way to do so fails. (shrink)

According to the Good True Self (GTS) theory, if an action is deemed good, its psychological source is typically viewed as more reflective of its agent’s true self, of who the agent really is ‘deep down inside’; if the action is deemed bad, its psychological source is typically viewed as more external to its agent’s true self. In previous work, we discovered a related asymmetry in judgments of blame- and praiseworthiness with respect to the mitigating effect of moral ignorance via (...) childhood deprivation. Inspired by work motivating the GTS theory, we ran a new study to discover whether our asymmetry likewise reflected judgments about the true self. It did. However, it is unclear whether our results fit with the ‘good’ part of the GTS theory: some of our and others’ results suggest that, in certain contexts, wrong actions are taken to be more expressive of agents’ true selves than right ones. In this paper, we propose that our and others’ data can be explained by the hypothesis that we are inclined to judge as the GTS theory predicts when there is a readily available external explanation for an agent’s action. In short, we give people the benefit of the doubt. (shrink)

We provide conditions under which an incomplete strongly independent preorder on a convex set X can be represented by a set of mixture preserving real-valued functions. We allow X to be infi nite dimensional. The main continuity condition we focus on is mixture continuity. This is sufficient for such a representation provided X has countable dimension or satisfi es a condition that we call Polarization.

This essay gives an account of how traditional morality is best understood and also why it is worth defending (even if some reform is needed) and how this might be done. Traditional morality is first contrasted with supposedly more enlightened forms of morality, such as utilitarianism and liberal Kantianism (i.e., autonomy-centered ethics). The focus here is on certain sacred values that are central to traditional morality and which highlight this contrast and bring out the attractions of traditional morality. Next, this (...) essay explores and offers support for the convergence thesis to which traditional morality, understood as common morality, is committed. This thesis states that although there are diverse moral traditions, insofar as they are in good order we should expect them to converge upon a common or universal morality, even if there remain some differences in the details. The defense of this thesis provides justification for the validity of traditional morality as it suggests an objective basis. (shrink)

The strongest arguments for the permissibility of geoengineering (also known as climate engineering) rely implicitly on non-ideal theory—roughly, the theory of justice as applied to situations of partial compliance with principles of ideal justice. In an ideally just world, such arguments acknowledge, humanity should not deploy geoengineering; but in our imperfect world, society may need to complement mitigation and adaptation with geoengineering to reduce injustices associated with anthropogenic climate change. We interpret research proponents’ arguments as an application of a particular (...) branch of non-ideal theory known as “clinical theory.” Clinical theory aims to identify politically feasible institutions or policies that would address existing (or impending) injustice without violating certain kinds of moral permissibility constraints. We argue for three implications of clinical theory: First, conditional on falling costs and feasibility, clinical theory provides strong support for some geoengineering techniques that aim to remove carbon dioxide from the atmosphere. Second, if some kinds of carbon dioxide removal technologies are supported by clinical theory, then clinical theory further supports using those technologies to enable “overshoot” scenarios in which developing countries exceed the cumulative emissions caps that would apply in ideal circumstances. Third, because of tensions between political feasibility and moral permissibility, clinical theory provides only weak support for geoengineering techniques that aim to manage incoming solar radiation.

Ontic structural realism (OSR) claims that all there is to the world is structure. But how can this slogan be turned into a worked-out metaphysics? Here I consider one potential answer: a metaphysical framework known as generalism (Dasgupta, 2009, 2016). According to the generalist, the most fundamental description of the world is not given in terms of individuals bearing properties, but rather, general facts about which states of affairs obtain. However, I contend that despite several apparent similarities between the positions, (...) generalism is unable to capture the two main motivations for OSR. I suggest instead that OSR should be construed as a meta-metaphysical position. (shrink)

I argue that, unlike your brain, you are not composed of other things: you are simple. My argument centers on what I take to be an uncontroversial datum: for any pair of conscious beings, it is impossible for the pair itself to be conscious. Consider, for instance, the pair comprising you and me. You might pinch your arm and feel a pain. I might simultaneously pinch my arm and feel a qualitatively identical pain. But the pair we form would not (...) feel a thing.1 Pairs of people themselves are incapable of experience. Call this The Datum. What explains The Datum? I think the following exhaust the reasonable options. (1) Pairs of people lack a sufficient number of immediate parts. (2) Pairs of people lack immediate parts capable of standing in the right sorts of relations to each other and their environment. (3) Pairs of people lack immediate parts of the right nature. (4) Pairs of people are not structures (they are unstructured collections of their two immediate parts). (5) Some combination of (1) – (4). Finally, (6) pairs of people are not simple. (shrink)

Henrich et al.'s conclusion that psychologists ought not assume uniformity of psychological phenomena depends on their descriptive claim that there is no pattern to the great diversity in psychological phenomena.

If the reliability of a source of testimony is open to question, it seems epistemically illegitimate to verify the source’s reliability by appealing to that source’s own testimony. Is this because it is illegitimate to trust a questionable source’s testimony on any matter whatsoever? Or is there a distinctive problem with appealing to the source’s testimony on the matter of that source’s own reliability? After distinguishing between two kinds of epistemically illegitimate circularity—bootstrapping and self-verification—I argue for a qualified version of (...) the claim that there is nothing especially illegitimate about using a questionable source to evaluate its own reliability. Instead, it is illegitimate to appeal to a questionable source’s testimony on any matter whatsoever, with the matter of the source’s own reliability serving only as a special case. (shrink)
