Brian Leftow offers a theist theory of necessity and possibility, and a new sort of argument for God's existence. He argues that necessities of logic and mathematics are determined by God's nature, but that it is events in God's mind - his imagination and choice - that account for necessary truths about concrete creatures.

Value pluralists believe in multiple dimensions of value. What does betterness along a dimension have to do with being better overall? Any systematic answer begins with the Strong Pareto principle: one thing is overall better than another if it is better along one dimension and at least as good along all others. We defend Strong Pareto from recent counterexamples and use our discussion to develop a novel view of dimensions of value, one which puts Strong Pareto on firmer footing. We (...) conclude by defending Dimensionalism, the hypothesis that overall value relations are determined solely by how things compare along value dimensions. These are first steps towards a more systematic value pluralism. (shrink)

Brian Hedden defends a radical view about the relationship between rationality, personal identity, and time. On the standard view, personal identity over time plays a central role in thinking about rationality, because there are rational norms for how a person's attitudes and actions at one time should fit with her attitudes and actions at other times. But these norms are problematic. They make what you rationally ought to believe or do depend on facts about your past that aren't part (...) of your current perspective on the world, and they make rationality depend on controversial, murky metaphysical facts about what binds different instantaneous snapshots into a single person extended in time. Hedden takes a different approach, treating the relationship between different time-slices of the same person as no different from the relationship between different people. On his account, the locus of rationality is the time-slice rather than the temporally extended agent. This impersonal, time-slice-centric approach to rationality yields a unified approach to the rationality of beliefs, preferences, and actions where what rationality demands of you is solely determined by your evidence, with no special weight given to your past beliefs or actions.

I advocate Time-Slice Rationality, the thesis that the relationship between two time-slices of the same person is not importantly different, for purposes of rational evaluation, from the relationship between time-slices of distinct persons. The locus of rationality, so to speak, is the time-slice rather than the temporally extended agent. This claim is motivated by consideration of puzzle cases for personal identity over time and by a very moderate form of internalism about rationality. Time-Slice Rationality conflicts with two proposed principles of (...) rationality, Conditionalization and Reflection. Conditionalization is a diachronic norm saying how your current degrees of belief should fit with your old ones, while Reflection is a norm enjoining you to defer to the degrees of belief that you expect to have in the future. But they are independently problematic and should be replaced by improved, time-slice-centric principles. Conditionalization should be replaced by a synchronic norm saying what degrees of belief you ought to have given your current evidence and Reflection should be replaced by a norm which instructs you to defer to the degrees of belief of agents you take to be experts. These replacement principles do all the work that the old principles were supposed to do while avoiding their problems. In this way, Time-Slice Rationality puts the theory of rationality on firmer foundations and yields better norms than alternative, non-time-slice-centric approaches. (shrink)

A textbook on modal logic, intended for readers already acquainted with the elements of formal logic, containing nearly 500 exercises. Brian F. Chellas provides a systematic introduction to the principal ideas and results in contemporary treatments of modality, including theorems on completeness and decidability. Illustrative chapters focus on deontic logic and conditionality. Modality is a rapidly expanding branch of logic, and familiarity with the subject is now regarded as a necessary part of every philosopher's technical equipment. Chellas here offers (...) an up-to-date and reliable guide essential for the student. (shrink)

"Brian Orend's The Morality of War promises to become the single most comprehensive and important book on just war for this generation. It moves far beyond the review of the standard just war categories to deal comprehensively with the new challenges of the conflict with terrorism. It thoughtfully reviews every major military conflict of the past few decades, mining them for implications of the evolving tradition of just war thinking. It concludes with a critical engagement with the major alternatives (...) to just war thinking: pacifism and 'realism.' It is, in short, the most comprehensive and thoughtful assessment of all aspects of just war since Michael Walzer's classic Just and Unjust Wars." - Martin L. Cook, United States Air Force Academy.

Authors have a lot of leeway with regard to what they can make true in their story. In general, if the author says that p is true in the fiction we’re reading, we believe that p is true in that fiction. And if we’re playing along with the fictional game, we imagine that, along with everything else in the story, p is true. But there are exceptions to these general principles. Many authors, most notably Kendall Walton and Tamar Szabó Gendler, (...) have discussed apparent counterexamples when p is “morally deviant”. Many other statements that are conceptually impossible also seem to be counterexamples. In this paper I do four things. I survey the range of counterexamples, or at least putative counterexamples, to the principles. Then I look to explanations of the counterexamples. I argue, following Gendler, that the explanation cannot simply be that morally deviant claims are impossible. I argue that the distinctive attitudes we have towards moral propositions cannot explain the counterexamples, since some of the examples don’t involve moral concepts. And I put forward a proposed explanation that turns on the role of ‘higher-level concepts’, concepts that if they are satisfied are satisfied in virtue of more fundamental facts about the world, in fiction, and in imagination.

Reichle et al. show that saccades in reading are controlled by linguistic processing. The authors' Figure 13 shows the parietal and frontal eye fields as parts of a neural implementation. This commentary presents data from dyslexics performing nonreading saccade tasks. The dyslexics exhibit deficits in antisaccade control. Improvement of the deficits is achieved in 85% of the cases and results in advantages in learning how to read.

Two visual phenomena are described in which oculomotor activity (saccades) changes our conscious perception: (1) some geometrical visual illusions disappear when saccades are suppressed, and (2) misperceptions occur in an antisaccade task with attentional precues. The first phenomenon shows that what we consciously perceive depends on how we look. The second phenomena indicates that a saccade itself may remain unconscious together with the accompanying changes of the retinal image.

This commentary considers experimental material – some new, some from earlier studies – challenging the model presented by Findlay & Walker. It concentrates on the role of voluntary and involuntary visual attention versus fixation in saccade control and on the generation of antisaccades, reflexive prosaccades, and corrective saccades. The data of a large number of subjects are presented to show the systematic relationship between voluntary saccade generation, error production, and error correction in an antisaccade task.

This volume provides a lucid and distinct introduction to multiculturalism and the philosophy of social science.

A counterpossible is a counterfactual whose antecedent is impossible. The vacuity thesis says all counterpossibles are true solely because their antecedents are impossible. Recently, some have rejected the vacuity thesis by citing purported non-vacuous counterpossibles in science. One limitation of this work, however, is that it is not grounded in experimental data. Do scientists actually reason non-vacuously about counterpossibles? If so, what is their basis for doing so? We presented biologists (N = 86) with two counterfactual formulations of a well-known (...) model in biology, the antecedents of which contain what many philosophers would characterize as a metaphysical impossibility. Participants consistently judged one counterfactual to be true, the other to be false, and they explained that they formed these judgments based on what they perceived to be the mathematical relationship between the antecedent and consequent. Moreover, we found no relationship between participants’ judgments about the (im)possibility of the antecedent and whether they judged a counterfactual to be true or false. These are the first experimental results on counterpossibles in science with which we are familiar. We present a modal semantics that can capture these judgments, and we deal with a host of potential objections that a defender of the vacuity thesis might make. (shrink)

A theoretical and sociological exploration of the relationship between law and society, this book constructs an approach to law that integrates legal theory with sociological approaches to law. Law is generally understood to be a mirror of society--a reflection of its customs and morals--that functions to maintain social order. Focusing on this common understanding, the book conducts a survey of Western legal and social theories about law and its relationship within society, engaging in a theoretical and empirical critique of this (...) common understanding.

This review note surveys some important aspects of a recent publication by Amos Edelheit, A Philosopher at the Crossroads: Giovanni Pico della Mirandola’s Encounter with Scholastic Philosophy. While focus over the last decades has been placed on Pico’s thought in relation to Jewish Kabbalah and mysticism, Edelheit hopes to emphasize the importance of the scholastic tradition (or, rather, the pluriform and various tradition of late medieval and Renaissance scholasticism) in Pico’s thought, and the ways in which this intellectual context places (...) this unique Renaissance thinker at a sort of ‘crossroads’. Beyond providing a brief overview of the three main parts of the text, this note examines more closely Edelheit’s study of Pico’s 900 Theses and the methodological approach which involves a reconstruction of the dialectical context for each thesis. The Latin scholastics are real conversational partners for Pico: he is versed in the 13th-century scholastic sources, is certainly familiar with contemporaneous scholastic thought, and is able to employ scholastic methods and terminology within his wider philosophical project. While scholastic philosophy was very much alive at the end of the fifteenth century, Pico’s new and inclusive approach to philosophy and the history of philosophy, never eschewing the Latin masters, departs from both scholastic and humanist trends.

In the first full-length analysis of Wittgenstein's Remarks on Frazer's Golden Bough, Brian R. Clack presents a fresh and innovative interpretation of Wittgenstein's conception of religion. While previous commentators have tended to sideline the Remarks on Frazer, Clack shows how the key to Wittgenstein's thought on religion lies in these remarks on primitive magico-religious observances. This book shows that Wittgenstein neither embraces expressivism, as it is generally assumed, nor straightforwardly denies instrumentalism. Focusing instead on Wittgenstein's suggestion that magic is (...) somehow akin to metaphysics, a view of ritual as the spontaneous expression of human beings is presented. (shrink)

ABSTRACT Quine insisted that the satisfaction of an open modalised formula by an object depends on how that object is described. Kripke's ‘objectual’ interpretation of quantified modal logic, whereby variables are rigid, is commonly thought to avoid these Quinean worries. Yet there remain residual Quinean worries for epistemic modality. Theorists have recently been toying with assignment-shifting treatments of epistemic contexts. On such views an epistemic operator ends up binding all the variables in its scope. One might worry that this yields (...) the undesirable result that any attempt to ‘quantify in’ to an epistemic environment is blocked. If quantifying into the relevant constructions is vacuous, then such views would seem hopelessly misguided and empirically inadequate. But a famous alternative to Kripke's semantics, namely Lewis' counterpart semantics, also faces this worry since it also treats the boxes and diamonds as assignment-shifting devices. As I'll demonstrate, the mere fact that a variable is bound is no obstacle to binding it. This provides a helpful lesson for those modelling de re epistemic contexts with assignment sensitivity, and perhaps leads the way toward the proper treatment of binding in both metaphysical and epistemic contexts: Kripke for metaphysical modality, Lewis for epistemic modality.

We live in a world of crowds and corporations, artworks and artifacts, legislatures and languages, money and markets. These are all social objects — they are made, at least in part, by people and by communities. But what exactly are these things? How are they made, and what is the role of people in making them? In The Ant Trap, Brian Epstein rewrites our understanding of the nature of the social world and the foundations of the social sciences. Epstein (...) explains and challenges the three prevailing traditions about how the social world is made. One tradition takes the social world to be built out of people, much as traffic is built out of cars. A second tradition also takes people to be the building blocks of the social world, but focuses on thoughts and attitudes we have toward one another. And a third tradition takes the social world to be a collective projection onto the physical world. Epstein shows that these share critical flaws. Most fundamentally, all three traditions overestimate the role of people in building the social world: they are overly anthropocentric. Epstein starts from scratch, bringing the resources of contemporary metaphysics to bear. In the place of traditional theories, he introduces a model based on a new distinction between the grounds and the anchors of social facts. Epstein illustrates the model with a study of the nature of law, and shows how to interpret the prevailing traditions about the social world. Then he turns to social groups, and to what it means for a group to take an action or have an intention. Contrary to the overwhelming consensus, these often depend on more than the actions and intentions of group members. (shrink)

In this chapter, we introduce the notion of “moral neuroenhancement,” offering a novel definition as well as spelling out three conditions under which we expect that such neuroenhancement would be most likely to be permissible (or even desirable). Furthermore, we draw a distinction between first-order moral capacities, which we suggest are less promising targets for neurointervention, and second-order moral capacities, which we suggest are more promising. We conclude by discussing concerns that moral neuroenhancement might restrict freedom or otherwise “misfire,” and (...) argue that these concerns are not as damning as they may seem at first.

How might the social sciences best be employed in the study of law, especially in light of today's legal climate of anti-foundationalism? Realistic Socio-Legal Theory addresses this question thoroughly and precisely. Drawing upon philosophical pragmatism to construct an epistemological and methodological foundation, this book formulates a framework for a realistic approach to socio-legal theory. Brian Z. Tamanaha contrasts the strengths of his realistic approach with those of the major schools of socio-legal theory through application to many key issues in (...) the field. He explores the problematic state of socio-legal studies, the relationship between behavior and meaning, the notion of legal ideology, the nature of the concept of law, the problem of indeterminacy in rule following and application, and the structure of judicial decision making. Tamanaha's discussion is always clear and concise as he articulates a social theory of law that draws equally from legal theory and socio-legal studies. His book has much to offer those interested in the gathering and organization of knowledge about law and legal phenomena. (shrink)

The old adage has two people out hiking who run into a bear. One starts running while the other asks ‘why are you running? You can’t outrun a bear’. To which the other responds, ‘I don’t have to outrun the bear. I only have to outrun you’. Hiking/trekking is not typically a competitive endeavor characterized by contests but, like many endeavors/pursuits/activities, competition can be injected into it; thereby sportifying it. Swimming is a sport (under certain conditions). At the same time, (...) it is also a recreational activity and a form of physical exercise; likewise angling/fishing, climbing, cross-country skiing, mountain biking, kayaking, rowing, surfing, et al. The categorization of many activities under the umbrella of sport has it uses to understand the wider concept of what is sport, but the purpose of why one engages in ‘physical activities taking place in a natural environment’ can sometimes be more important than whether some activities might or might not qualify to be classified under the rubric of sports at all. Indicators exist to show whether participants are actually engaged toward—driven in a way, even—to further their skills in their focused activity (if it is a focused activity at all!––i.e. a ‘serious leisure’ pursuit or just a recreational hobby). From this perspective (of looking at sport-like and sporting activities in other than Olympic-style forms) this paper explores the differentiations between sport (including nature sport) contests, nature challenge activities (NCAs) and outdoor recreation from the standpoint of the most relevant factors that distinguish them: rules, skill development, purpose for engaging in them. This paper also makes the case that differentiating participants in the above activities by purpose (as either nature challenge recreationalists or nature sport devotees) has utility; to better help research into people’s engagement in physical activities in natural environments.

The foundational principles of representative democracy are under attack globally. What we desperately need are enlightened and persuasive public intellectuals who can help us see through the fog of our fear, anger, and disillusionment, to find our rational political commitments again. One of these public intellectuals is undoubtedly Yuval Noah Harari, the bestselling author of three recent books – Sapiens, Homo Deus, and 21 Lessons for the 21st Century. Harari is also a frequent contributor in the popular press, and a (...) guest on shows, podcasts, panels, and as a keynote speaker. Add to all this that Harari is acting on his lofty academic ideals through ‘Sapienship’, a multidisciplinary organization he cofounded that advocates for global responsibility, clarifies the global conversation, and focuses attention on the most important global challenges. I single out Harari because I presume many readers will be familiar with his work. He is certainly one of the fastest rising stars of public intellectualism. Unfortunately, his work is undercut by the philosophical positions he put forth in his first bestselling book, Sapiens. In this review/critique I wish to show that in order for Harari advance a coherent political or ideological argument, he must first shore up his philosophical commitments. (shrink)

All major western countries today contain groups that differ in their religious beliefs, customary practices or ideas about the right way in which to live. How should public policy respond to this diversity? In this important new work, Brian Barry challenges the currently orthodox answer and develops a powerful restatement of an egalitarian liberalism for the twenty-first century. Until recently it was assumed without much question that cultural diversity could best be accommodated by leaving cultural minorities free to associate (...) in pursuit of their distinctive ends within the limits imposed by a common framework of laws. This solution is rejected by an influential school of political theorists, among whom some of the best known are William Galston, Will Kymlicka, Bhikhu Parekh, Charles Taylor and Iris Marion Young. According to them, this 'difference-blind' conception of liberal equality fails to deliver either liberty or equal treatment. In its place, they propose that the state should 'recognize' group identities, by granting groups exemptions from certain laws, publicly 'affirming' their value, and by providing them with special privileges or subsidies. In Culture and Equality, Barry offers an incisive critique of these arguments and suggests that theorists of multiculturism tend to misdiagnose the problems of minority groups. Often, these are not rooted in culture, and multiculturalist policies may actually stand in the way of universalistic measures that would be genuinely beneficial. (shrink)

This chapter provides a general overview of the issues surrounding so-called semantic monsters. In section 1, I outline the basics of Kaplan’s framework and spell out how and why the topic of “monsters” arises within that framework. In Section 2, I distinguish four notions of a monster that are discussed in the literature, and show why, although they can pull apart in different frameworks or with different assumptions, they all coincide within Kaplan’s framework. In Section 3, I discuss one notion (...) that has spun off into the linguistics literature, namely “indexical shift”. In Section 4, I emphasize the connection between monsters and the compositionality of asserted content in Kaplan’s original discussion. Section 5 discusses monsters and the more general idea of re-interpretation or meaning-shift. Section 6 closes with a brief survey of where monsters may dwell, and pointers to avenues for future research. (shrink)

Almost entirely ignored in the linguistic theorising on names and descriptions is a hybrid form of expression which, like definite descriptions, begin with 'the' but which, like proper names, are capitalised and seem to lack descriptive content. These are expressions such as the following, 'the Holy Roman Empire', 'the Mississippi River', or 'the Space Needle'. Such capitalised descriptions are ubiquitous in natural language, but to which linguistic categories do they belong? Are they simply proper names? Or are they definite descriptions (...) with unique orthography? Or are they something else entirely? This paper assesses two obvious assimilation strategies: (i) assimilation to proper names and (ii) assimilation to definite descriptions. It is argued that both of these strategies face major difficulties. The primary goal is to lay the groundwork for a linguistic analysis of capitalised descriptions. Yet, the hope is that clearing the ground on capitalised descriptions may reveal useful insights for the on-going research into the semantics and syntax of their lower-case or 'the'-less relatives.

The question of what makes someone the same person through time and change has long been a preoccupation of philosophers. In recent years, the question of what makes ordinary or lay people judge that someone is—or isn’t—the same person has caught the interest of experimental psychologists. These latter, empirically oriented researchers have sought to understand the cognitive processes and eliciting factors that shape ordinary people’s judgments about personal identity and the self. Still more recently, practitioners within an emerging discipline, experimental (...) philosophical bioethics or “bioxphi”—the focus of this chapter—have adopted a similar aim and employed similar methodologies, but with two distinctive features: (a) a special concern for enhanced ecological validity in the examples and populations studied; and (b) an interest in contributing to substantive normative debates within the wider field of bioethics. Our aim in this chapter is to sample illustrative work on personal identity in bioxphi, explore how it relates to studies in psychology covering similar terrain, and draw out the implications of this work for matters of bioethical concern. In pursuing these issues, we highlight recent work in bioxphi that includes the perceived validity of advance directives following neurodegeneration, the right of psychologically altered study participants to withdraw from research, how drug addiction may cause one to be regarded by others as “a completely different person,” the effect of deep-brain stimulation on perceptions of the self, and the potential influence of moral enhancement interventions on intuitive impressions of a person’s character.

This essay investigates whether or not we should think that the things we say are identical to the things our sentences mean. It is argued that these theoretical notions should be distinguished, since assertoric content does not respect the compositionality principle. As a paradigmatic example, Kaplan's formal language LD is shown to exemplify a failure of compositionality. It is demonstrated that by respecting the theoretical distinction between the objects of assertion and compositional values certain conflicts between compositionality and contextualism are (...) avoided. This includes the conflict between eternalism and the semantics of tense, the embedding problems for contextualism about epistemic modals and taste claims, and the conflict between direct reference and the semantics of bound pronouns (and monstrous operators). After presenting the theoretical picture which distinguishes assertoric content from compositional semantic value, some objections to the picture are addressed. In so doing, the objection from King (2003) stemming from apparent complications with the interaction of temporal expressions and attitude reports is assessed and shown to be non-threatening.

Does appraisal co-ordinate emotional responses? Are emotions usually reached via mental representations of relational meaning? This comment considers alternative causal routes in order to assess the centrality of appraisal in the explanation of emotion. Implicit and explicit meaning extraction can certainly help steer the course of emotion-related processes. However, presupposing that appraisals represent the driving force behind all aspects of emotion generation leads to inclusive formulations of appraisal or restrictive formulations of emotion.

Almost every country today contains adherents of different religions and different secular conceptions of the good life. Is there any alternative to a power struggle among them, leading most probably to either civil war or repression? The argument of this book is that justice as impartiality offers a solution. According to the theory of justice as impartiality, principles of justice are those principles that provide a reasonable basis for the unforced assent of those subject to them. The object of this (...) book is to set the theory out, explain its rationale, and respond to a variety of criticism that have been made of it. As the second volume of his work-in-progress, A Treatise on Social Justice, this work lies at the heart of a thriving academic debate which the author has played a key role in shaping. (shrink)

Kaplan (1989a) insists that natural languages do not contain displacing devices that operate on character—such displacing devices are called monsters. This thesis has recently faced various empirical challenges (e.g., Schlenker 2003; Anand and Nevins 2004). In this note, the thesis is challenged on grounds of a more theoretical nature. It is argued that the standard compositional semantics of variable binding employs monstrous operations. As a dramatic first example, Kaplan’s formal language, the Logic of Demonstratives, is shown to contain monsters. For (...) similar reasons, the orthodox lambda-calculus-based semantics for variable binding is argued to be monstrous. This technical point promises to provide some far-reaching implications for our understanding of semantic theory and content. The theoretical upshot of the discussion is at least threefold: (i) the Kaplanian thesis that “directly referential” terms are not shiftable/bindable is unmotivated, (ii) since monsters operate on something distinct from the assertoric content of their operands, we must distinguish ingredient sense from assertoric content (cf. Dummett 1973; Evans 1979; Stanley 1997), and (iii) since the case of variable binding provides a paradigm of semantic shift that differs from the other types, it is plausible to think that indexicals—which are standardly treated by means of the assignment function—might undergo the same kind of shift.

When we say that what two people feel for each other is 'true love,' we seem to be doing more than simply clarifying that it is in fact love they feel, as opposed to something else. That is, an experience or relationship might be a genuine or actual instance of love without necessarily being an instance of true love. But what criteria do people use to determine whether something counts as true love? This chapter explores three hypotheses. The first holds (...) that the ordinary concept of true love picks out love that is highly prototypical. The second, that it picks out love that is especially good or valuable. The third, that people distinguish between psychological states that are 'real' or not, and that it picks out love that is real. Two experiments provide evidence against the first hypothesis and in favor of the second and third. Implications for real-life disagreements about love are also discussed. (shrink)

This paper develops a new argument from consciousness to theism: the argument from psychophysical harmony. Roughly, psychophysical harmony consists in the fact that phenomenal states are correlated with physical states and with one another in strikingly fortunate ways. For example, phenomenal states are correlated with behavior and functioning that is justified or rationalized by those very phenomenal states, and phenomenal states are correlated with verbal reports and judgments that are made true by those very phenomenal states. We argue that psychophysical (...) harmony is strong evidence for theism (or, at least, strong evidence against atheism in its standard naturalistic form). (shrink)

Available from UMI in association with The British Library. ;A form of metaphysical inquiry is in this thesis both illustrated in detail and defended against the charge of issuing in statements which lack cognitive content. 'Categorial description' concerns the fundamental features of our conceptual scheme: the categories described are those of substance, accident, cause, space and time. ;Following Aristotle's distinction between primary and secondary substances, these two notions are addressed as equivalent to those individual or particular things and their kinds. (...) A particular thing is characterised as not being capable of occuring in the predicate position in a proposition; and as having criteria or principles of individuation and reidentification. Accidents or properties can appear in the predicate position and do not have criteria of identity. ;Secondary substances, or natural kinds, being a species of property, also fail to have criteria for individuation and reidentification. It follows that the recently revived Aristotelian essentialism, as exhibited in particular in the work of Kripke, fails to correctly characterise the category of natural kinds: in that theory, natural kinds have essential properties which enable individuation and reidentification across possible worlds. ;Efficient causation is described, against the background of the Locke-Hume dispute, as involving the concept of necessary connection between cause and effect. Rejecting the theory of Harre and Madden on causal powers, an approach by Mackie is defended whereby this connection is a reflection of our counterfactual thinking. The possible worlds essentialist approach of Lewis to counterfactuals is rejected too, as inadequate. ;Space and time, spatial and temporal relations, and places and moments in time are approached in terms of the other categories of particular and property. The obscurity of fit between these categories is identified as responsible for many philosophical puzzles concerning space and time: for example, McTaggart's 'proof' of the unreality of time; and the recent debate on the possibility of multiple times and multiple spaces. ;In the final chapter, the logical commitments of categorial description concerning conceptual relativism and the nature of reality in itself are explored. It is argued that, since categories are in large part responsible for the kinds of acts there are, a description of our categories is a description of reality itself. Since our categories do not involve the machinery of possible worlds offered by contemporary essentialist theories, those theories fail to describe reality. (shrink)
