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)

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 paper aims to shed new light on certain philosophical theories of perceptual experience by examining the semantics of perceptual ascriptions such as “Jones sees an apple.” I start with the assumption, recently defended elsewhere, that perceptual ascriptions lend themselves to intensional readings. In the first part of the paper, I defend three theses regarding such readings: I) intensional readings of perceptual ascriptions ascribe phenomenal properties, II) perceptual verbs are not ambiguous between intensional and extensional readings, and III) intensional perceptual (...) ascriptions have a relational form. The second part of the paper describes the implications of I-III for theories of perceptual experience. I argue that I-III support and reconcile the three main views of perceptual experience, relationalism, disjunctivism, and representationalism. However, I-III leave open at least one important point of contention: particularism, the view that we experience external objects. I conclude by exploring the implications of accepting or denying particularism given I-III. (shrink)

Intermodal representationalists hold that the phenomenal characters of experiences are fully determined by their contents. In contrast, intramodal representationalists hold that the phenomenal characters of experiences are determined by their contents together with their intentional modes or manners of representation, which are nonrepresentational features corresponding roughly to the sensory modalities. This paper discusses a kind of experience that provides evidence for an intermodal representationalist view: intermodal experiences, experiences that unify experiences in different modalities. I argue that such experiences are much (...) easier to explain on the intermodal view. (shrink)

Evaluativism is best thought of as a way of enriching a perceptual view of pain to account for pain’s unpleasantness or painfulness. Once it was common for philosophers to contrast pains with perceptual experiences (McGinn 1982; Rorty 1980). It was thought that perceptual experiences were intentional (or content-bearing, or about something), whereas pains were representationally blank. But today many of us reject this contrast. For us, your having a pain in your toe is a matter not of your sensing “pain-ly” (...) or encountering a sense-datum, but of your having an interoceptive experience representing (accurately or inaccurately) that your toe is in a particular experience-independent condition, such as undergoing a certain “disturbance” or being damaged or in danger (Armstrong 1962; Tye 1995). But even if such representational content makes an experience a pain, a further ingredient seems required to make the pain unpleasant. According to evaluativism, the further ingredient is the experience’s possession of evaluative content: its representing the bodily condition as bad for the subject. In this chapter, I elaborate evaluativism, locate it among alternatives, and explain its attractions and challenges. (shrink)

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.

Ethnobiology has a long tradition of metaphysical debates about the “naturalness,” “objectivity”, “reality”, and “universality” of classifications. Especially the work of Brent Berlin has been influential in developing a “convergence metaphysics” that explains cross-cultural similarities of knowledge systems through shared recognition of objective discontinuities in nature. Despite its influence on the development of the field, convergence metaphysics has largely fallen out of favor as contemporary ethnobiologists tend to emphasize the locality and diversity of classificatory practices. The aim of this article (...) is twofold: First, I provide a historical account of the rise and fall of convergence metaphysics in ethnobiology. I show how convergence metaphysics emerged as an innovative theoretical program in the wake of the “cognitive revolution” and the “modern evolutionary synthesis” but failed to incorporate both theoretical insights and political concerns that gained prominence in the 1980s and 1990s. Second, I develop a positive proposal of how to engage with metaphysical issues in ethnobiology. By integrating traditional research on convergence of classifications with more nuanced accounts of distinctly local categories, a revamped metaphysics of ethnobiological classification can make substantial contributions to debates about ontological difference in anthropology and about the relation between applied and theoretical ethnobiology.

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.

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)

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.

Eleanor Knox has argued that our concept of spacetime applies to whichever structure plays a certain functional role in the laws (the role of determining local inertial structure). I raise two complications for this approach. First, our spacetime concept seems to have the structure of a cluster concept, which means that Knox's inertial criteria for spacetime cannot succeed with complete generality. Second, the notion of metaphysical fundamentality may feature in the spacetime concept, in which case spacetime functionalism may be uninformative (...) in the absence of answers to fundamental metaphysical questions like the substantivalist/relationist debate.

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.

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)

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.

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.

This paper challenges the soundness of the two-dimensional conceivability argument against the derivation of phenomenal truths from physical truths in light of a hyperintensional, ground-theoretic regimentation of the ontology of consciousness. The regimentation demonstrates how ontological dependencies between truths about consciousness and about physics cannot be witnessed by epistemic constraints, when the latter are recorded by the conceivability—i.e., the epistemic possibility—thereof. Generalizations and other aspects of the philosophical significance of the hyperintensional regimentation are further examined.

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)

This is a précis of my book "Know-how as Competence. A Rylean Responsibilist Account".

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)

I explore the place of manners in the moral life, particularly with regard to their role in virtue education and in expressing virtue. The approach developed here is Aristotelian and Confucian in character. I identify and discuss three crucial functions of good manners: (1) they help social life to go well; (2) they often involve ways of showing respect or reverence for that which is respect-worthy or reverence-worthy; and (3) they ennoble our animal nature via an acquired second nature. In (...) light of this account I also discuss how concerns about arbitrariness, oppressiveness, and dishonesty with respect to manners can be overcome. (shrink)

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

World Crisis and Underdevelopment examines the impact of poverty and other global crises in generating forms of structural coercion that cause agential and societal underdevelopment. It draws from discourse ethics and recognition theory in criticizing injustices and pathologies associated with underdevelopment. Its scope is comprehensive, encompassing discussions about development science, philosophical anthropology, global migration, global capitalism and economic markets, human rights, international legal institutions, democratic politics and legitimation, world religions and secularization, and moral philosophy in its many varieties.

This paper responds to comments and criticisms by Stefan Brandt and Eva-Maria Jung, directed at the book "Know-how as Competence. A Rylean Responsibilist Account".

As an evaluative view in the philosophy of life, nihilism maintains that no lives are, all things considered, worth living. Prominent defenders of the view hold that, even so, it can be all-things-considered better for us to continue living than for us to cease living, thus endorsing a 'soft' nihilism that appears more palatable than its 'hard' counterpart. In support of an intuitive assumption about what nihilism implies, I argue that soft nihilism is incoherent.

The ancient doctrine of the eternal return of the same embodies a thoroughgoing rejection of the hope that the future world will be better than the present. For this reason, it might seem surprising that Leibniz constructs an argument for a version of the doctrine. He concludes in one text that in the far distant future he himself ‘would be living in a city called Hannover located on the Leine river, occupied with the history of Brunswick, and writing letters to (...) the same friends with the same meaning.’ However, his argument concludes not that the future will be absolutely identical to the present, but rather that any finite description of the present and future worlds would be identical. In this way, the argument leaves room for the promise of a different and better future—even if it is one that could not be recognized by us as such. (shrink)

In this essay I build on John Cottingham’s suggestion that we need an epistemology of involvement (or receptivity), as opposed to an epistemology of detachment, if we are properly to understand the world in religious terms. I also refer to these as ‘engaged’ and ‘disengaged’ stances. I seek to show how the spiritual practice of an ‘active’ or ‘engaged’ love is integral to the sort of epistemology of involvement through which we come to a religious understanding of the world. Such (...) an understanding is one that gives proper recognition to the sacred or reverence-worthy character of the world. I discuss how a religiously-inflected language of love and the practice it informs can transfigure the world for us and enable its sacred or reverence-worthy character to come into view (supposing it is there in any case). I also seek to show how this is connected to a process of spiritual formation (or Bildung). (shrink)

We present data and argument to show that in Tetris - a real-time interactive video game - certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as using the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to (...) change the world in order to simplify the problem-solving task. Thus, we distinguish pragmatic actions ñ actions performed to bring one physically closer to a goal - from epistemic actions - actions performed to uncover information that is hidden or hard to compute mentally. To illustrate the need for epistemic actions, we first develop a standard information-processing model of Tetris-cognition, and show that it cannot explain performance data from human players of the game - even when we relax the assumption of fully sequential processing. Standard models disregard many actions taken by players because they appear unmotivated or superfluous. However, we describe many such actions that are actually taken by players that are far from superfluous, and that play valuable roles in improving human performance. We argue that traditional accounts are limited because they regard action as having a single function: to change the world. By recognizing a second function of action - an epistemic function - we can explain many of the actions that a traditional model cannot. Although, our argument is supported by numerous examples specifically from Tetris, we outline how the one category of epistemic action can be incorporated into theories of action more generally.

Over recent decades, pain has received increasing attention as – with ever greater sophistication and rigour – theorists have tried to answer the deep and difficult questions it poses. What is pain’s nature? What is its point? In what sense is it bad? The papers collected in this volume are a contribution to that effort ...

Plato is mistaken on both sides of his distinction between Socrates and the Sophists. He imagines the Sophists to have a formless power that cannot be resisted. This exaltation of the power of persuasion needs to be seen as motivating excessive fears in various modern debates. Pragmatic approaches can lessen our fear.

A study timeshowing that the relation of time and timeless in greek philosophers was more nuanced and complex than is commonly thought.

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 have been to push those experiments all the way to some Western form of employee ownership or worker cooperatives operating in a full market environment. Alternatively, all these decentralizing experiments could be condemned as "vestiges of communism" to be eradicated by renationalizing all the decentralized firms and then privatizing by some alternative means.

Significant associations have been found between specific human leukocyte antigen (HLA) alleles and organ transplant rejection, autoimmune disease development, and the response to infection. Traditional searches for disease associations have conventionally measured risk associated with the presence of individual HLA alleles. However, given the high level of HLA polymorphism, the pattern of amino acid variability, and the fact that most of the HLA variation occurs at functionally important sites, it may be that a combination of variable amino acid sites shared (...) by several alleles (shared epitopes) are better descriptors of the actual causative genetic variants. Here we describe a novel approach to genetic association analysis in which genes/proteins are broken down into smaller sequence features and then variant types defined for each feature, allowing for independent analysis of disease association with each sequence feature variant type. We have used this approach to analyze a cohort of systemic sclerosis patients and show that a sequence feature composed of specific amino acid residues in peptide binding pockets 4 and 7 of HLA-DRB1 explains much of the molecular determinant of risk for systemic sclerosis.

Computers may help us to better understand (not just verify) arguments. In this article we defend this claim by showcasing the application of a new, computer-assisted interpretive method to an exemplary natural-language ar- gument with strong ties to metaphysics and religion: E. J. Lowe’s modern variant of St. Anselm’s ontological argument for the existence of God. Our new method, which we call computational hermeneutics, has been particularly conceived for use in interactive-automated proof assistants. It aims at shedding light on the (...) meanings of words and sentences by framing their inferential role in a given argument. By employing automated theorem reasoning technology within interactive proof assistants, we are able to drastically reduce (by several orders of magnitude) the time needed to test the logical validity of an argu- ment’s formalization. As a result, a new approach to logical analysis, inspired by Donald Davidson’s account of radical interpretation, has been enabled. In computational hermeneutics, the utilization of automated reasoning tools ef- fectively boosts our capacity to expose the assumptions we indirectly commit ourselves to every time we engage in rational argumentation and it fosters the explicitation and revision of our concepts and commitments.

Information may be defined as the conceptual or communicable part of the content of mental acts. The content of mental acts includes sensory data as well as concepts, particular as well as general information. An information system is an external (non-mental) system designed to store such content. Information systems afford indirect transmission of content between people, some of whom may put information into the system and others who are among those who use the system. In order for communication to happen, (...) the conceptual systems of the originators and users of the information must be sufficiently similar. A formal conceptual framework that can provide the basis for exchange of information is termed an ontology. In its most fundamental form, ontology studies the most basic constituents of reality. Traditionally, ontology seeks to reflects structures that are independent of thought and cognition. The term ontology is used more broadly in artificial intelligence and software engineering, to refer to the conceptual basis for an information system. (shrink)

Sometimes the philosophical armchair gets bumped by empirical facts. So it is when thinking about pain. For good or ill (good, actually, as we shall see) most of us are intimately acquainted with physical pain, the kind you feel when you stand on a nail or burn your hand. And, from the armchair, it can seem blindingly obvious that pain is essentially unpleasant. There are of course unpleasant experiences that aren’t pains – nausea or itches, for example – but surely (...) there aren’t pains that don’t hurt, pains that are neutral or even pleasurable rather than unpleasant. Surely, indeed, there couldn’t be. For it is part of the very concept of a pain that a pain be unpleasant. Or so it has seemed to many. Yet over recent decades philosophers’ confidence in these putative truisms has been shaken by some fascinating cases from the clinic, the lab, and life. (shrink)

Scholarly hypertexts involve argument and explicit selfquestioning, and can be distinguished from both informational and literary hypertexts. After making these distinctions the essay presents general principles about attention, some suggestions for self-representational multi-level structures that would enhance scholarly inquiry, and a wish list of software capabilities to support such structures. The essay concludes with a discussion of possible conflicts between scholarly inquiry and hypertext.

Philosophers think of pain less and less as a paradigmatic instance of mentality, for which they seek a general account, and increasingly as a rich and fruitful topic in its own right. Pain raises specific questions: about mentality and consciousness certainly, but also about embodiment, affect, motivation, and value, to name but a few. The growth of philosophical interest in pain has gone hand-in-hand with the growth of pain science, which burgeoned in the 1960s. This is no accident: developments in (...) pain science have prompted philosophers to take account of empirical data, and to revisit their assumptions about pain. Pain, in short, demands interdisciplinary investigation, hence while this entry focuses on the philosophy of pain, it makes liberal reference to empirical literature along the way. This entry’s focus is on physical pains, that is pains that are felt in bodily locations, not emotional suffering more broadly, such as grief or disappointment. The entry also does not address pain’s place in ethical theories; its focus is rather on issues that arise within philosophy of mind. Even so, part of what makes pain such an interesting and important topic is that the questions it raises span boundaries, and normative questions concerning pain’s badness, on the one hand, and its value, on the other, are never far away.

Functional intentionality is the dominant theory about how mental states come to have the content that they do. Phenomenal intentionality is an increasingly popular alternative to that orthodoxy, claiming that intentionality cannot be functionalized and that nothing is a mental state with intentional content unless it is phenomenally conscious. There is a consensus among defenders of phenomenal intentionality that the kind of phenomenology that is both necessary and sufficient for having a belief that "there is a tree in the quad" (...) is that the agent be consciously aware of the meaning of "tree" and "quad". On this theory, experiences with a valence -- experiences like happiness and sadness, satisfaction and frustration -- are irrelevant to intentionality. This paper challenges that assumption and considers several versions of "valent phenomenal intentionality" according to which a capacity for valent conscious experiences is either a necessary or a sufficient condition for intentionality (or both).

Category theory has foundational importance because it provides conceptual lenses to characterize what is important and universal in mathematics—with adjunctions being the primary lens. If adjunctions are so important in mathematics, then perhaps they will isolate concepts of some importance in the empirical sciences. But the applications of adjunctions have been hampered by an overly restrictive formulation that avoids heteromorphisms or hets. By reformulating an adjunction using hets, it is split into two parts, a left and a right semiadjunction. Semiadjunctions (...) (essentially a formulation of universal mapping properties using hets) can then be combined in a new way to define the notion of a brain functor that provides an abstract model of the intentionality of perception and action (as opposed to the passive reception of sense-data or the reflex generation of behavior).
