Chellas here offers (...) an up-to-date and reliable guide essential for the student. (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)

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)

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)

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.

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.

Social ontology is the study of the nature and properties of the social world. It is concerned with analyzing the various entities in the world that arise from social interaction. -/- A prominent topic in social ontology is the analysis of social groups. Do social groups exist at all? If so, what sorts of entities are they, and how are they created? Is a social group distinct from the collection of people who are its members, and if so, how is (...) it different? What sorts of properties do social groups have? Can they have beliefs or intentions? Can they perform actions? And if so, what does it take for a group to believe, intend, or act? -/- Other entities investigated in social ontology include money, corporations, institutions, property, social classes, races, genders, artifacts, artworks, language, and law. It is difficult to delineate a precise scope for the field (see section 2.1). In general, though, the entities explored in social ontology largely overlap with those that social scientists work on. A good deal of the work in social ontology takes place within the social sciences (see sections 5.1–5.8). -/- Social ontology also addresses more basic questions about the nature of the social world. One set of questions pertains to the constituents, or building blocks, of social things in general. For instance, some theories argue that social entities are built out of the psychological states of individual people, while others argue that they are built out of actions, and yet others that they are built out of practices. Still other theories deny that a distinction can even be made between the social and the non-social. -/- A different set of questions pertains to how social categories are constructed or set up. Are social categories and kinds produced by our attitudes? By our language? Are they produced by causal patterns? And is there just one way social categories are set up, or are there many varieties of social construction? -/- The term ‘social ontology’ has only come into wide currency in recent years, but the nature of the social has been a topic of inquiry since ancient Greece. As a whole, the field can be understood as a branch of metaphysics, the general inquiry into the nature of entities. (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)

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.

A common framing has it that any adequate treatment of quotation has to abandon one of the following three principles: (i) The quoted expression is a syntactic constituent of the quote phrase; (ii) If two expressions are derived by applying the same syntactic rule to a sequence of synonymous expressions, then they are synonymous; (iii) The language contains synonymous but distinct expressions. In the following, a formal syntax and semantics will be provided for a quotational language which adheres to all (...) three principles. The point here is not merely to provide a “possibility proof”, but to reveal the hard constraints on the theory of quotation, and to highlight certain assumptions at the syntax/semantics/post-semantics interfaces.

There is growing consensus that reward plays an important role in the control of attention. Until recently, reward was thought to influence attention indirectly by modulating task-specific motivation and its effects on voluntary control over selection. Such an account was consistent with the goal-directed (endogenous) versus stimulus-driven (exogenous) framework that had long dominated the field of attention research. Now, a different perspective is emerging. Demonstrations that previously reward-associated stimuli can automatically capture attention even when physically inconspicuous and task-irrelevant challenge previously (...) held assumptions about attentional control. The idea that attentional selection can be value driven, reflecting a distinct and previously unrecognized control mechanism, has gained traction. Since these early demonstrations, the influence of reward learning on attention has rapidly become an area of intense investigation, sparking many new insights. The result is an emerging picture of how the reward system of the brain automatically biases information processing. Here, I review the progress that has been made in this area, synthesizing a wealth of recent evidence to provide an integrated, up-to-date account of value-driven attention and some of its broader implications.

The relation between the Greek and Judeo-Christian traditions is "the great problem" of Western philosophy, according to Emmanuel Levinas. In this book Brian Schroeder, Silvia Benso, and an international group of philosophers address the relationship between Levinas and the world of ancient thought. In addition to philosophy, themes touching on religion, mythology, metaphysics, ontology, epistemology, ethics, and politics are also explored. The volume as a whole provides a unified and extended discussion of how an engagement between Levinas and thinkers (...) from the ancient tradition works to enrich understandings of both. This book opens new pathways in ancient and modern philosophical studies as it illuminates new interpretations of Levinas' ethics and his social and political philosophy. (shrink)

Epistemology orthodoxy is a purist one in the sense that it separates out the epistemic from the practical. What counts as evidence is independent of what we care about. Which beliefs count as justified and which count as knowledge are independent of our practical concerns. In recent years, many epistemologists have abandoned such purist views and embraced varying degrees of pragmatic encroachment on the epistemic. I survey a variety of these views and explore the main arguments that proponents of pragmatic (...) encroachment have offered in addition to the main criticisms of the pragmatic approach. (shrink)

The Metaphysical Club, a gathering of intellectuals in the 1870s associated with Harvard, is widely recognized as the crucible where pragmatism, America's distinctively original philosophy, was refined and proclaimed. Louis Menand's bestseller about the group was a dramatic publishing success. However, only three actual members - Oliver Wendell Holmes Jr., Charles S. Peirce, and William James - appear in this book, alongside other thinkers such as John Dewey who were never in the Club. The Real Metaphysical Club tells the full (...) story of how this influential group shifted the course of philosophy in America. In addition to pioneering pragmatism, the group explored radical empiricism and idealism, and formulated personalism and process philosophy, equally important developments. This volume contains thirty-seven important writings dating from 1870 to 1885 by the real members of the Metaphysical Club. The first section centers on pragmatism and science; the second part collects writings of the lawyers; and the third part covers idealist and personalist philosophers. Many of these writings have never been reprinted before, and nothing like this impressive collection has ever been attempted. A general introduction provides a narrative history, and the editors' three introductions to the volume's sections vividly bring to life the intense meetings, sustained debates, and pioneering thought from the Metaphysical Club.

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.

"John Rawls's A Theory of Justice has been widely acclaimed as a book whose influence on the discussion of central questions in moral and political philosophy will be permanent. A brief review, writes Dr. Barry, would be of little more value than would be a brief review of Hobbes's Leviathan; instead, in this book he interprets Rawls's main tenets and discusses them with appropriate thoroughness. The book is in three parts. Chapters 1-5 set Rawls's theory in its intellectual context and (...) give an account of its basic features. Chapters 6-11 examine Rawls's claim to have advanced 'two principles of justice' and provided a logical deduction of them by showing that men denied various kinds of information about themselves and their society would choose them as the most rational way of advancing their 'conception of the good'. Chapters 12-15 extend the discussion to cover the most important of Rawls's economic and political deductions. Dr. Barry's argument is that Rawls's 'theory of justice' does not work; but that A Theory of Justice is nonetheless a work with which 'anyone in future who proposes to deal with any of the topics it touches must first come to terms'. His critique may be read either in conjunction with A Theory of Justice (there is a concordance of passages discussed) or independently of it." -- Backcover. (shrink)

According to the AI ensoulment hypothesis, some future AI systems will be endowed with immaterial souls. I argue that we should have at least a middling credence in the AI ensoulment hypothesis, conditional on our eventual creation of AGI and the truth of substance dualism in the human case. I offer two arguments. The first relies on an analogy between aliens and AI. The second rests on the conjecture that ensoulment occurs whenever a physical system is “fit to possess” a (...) soul, where very roughly this amounts to being physically structured in such a way that the system can meaningfully cooperate with the operations of the soul.

Safety-based theories of knowledge face a difficulty surrounding necessary truths: no subject could have easily falsely believed such a proposition. Failing to predict that ill-grounded beliefs in such propositions do not constitute knowledge, standard safety theories are therefore less informative than desired. Some have suggested that the subjects at issue could easily have believed some related false proposition; but they have given no indication as to what makes a proposition related. I suggest a solution to this problem: a belief is (...) safe iff its subject could not easily have believed a false answer to the same question. (shrink)

Virtues are acquirable, so if intellectual humility is a virtue, it’s acquirable. But there is something deeply problematic—perhaps even paradoxical—about aiming to be intellectually humble. Drawing on Edward Slingerland’s analysis of the paradoxical virtue of wu-wei in Trying Not To Try (New York: Crown, 2014), we argue for an anti-individualistic conception of the trait, concluding that one’s intellectual humility depends upon the intellectual humility of others. Slingerland defines wu-wei as the “dynamic, effortless, and unselfconscious state of mind of a person (...) who is optimally active and effective” (Trying Not to Try, 7). Someone who embodies wu-wei inspires implicit trust, so it is beneficial to appear wu-wei. This has led to an arms race between faking wu-wei on the one hand and detecting fakery on the other. Likewise, there are many benefits to being (or seeming to be) intellectually humble. But someone who makes conscious, strategic efforts to appear intellectually humble is ipso facto not intellectually humble. Following Slingerland’s lead, we argue that there are several strategies one might pursue to acquire genuine intellectual humility, and all of these involve commitment to shared social or epistemic values, combined with receptivity to feedback from others, who must in turn have and manifest relevant intellectual virtues. In other words, other people and shared values are partial bearers of a given individual’s intellectual humility. If this is on the right track, then acquiring intellectual humility demands epistemic anti-individualism. (shrink)

On the Origin of Objects is the culmination of Brian Cantwell Smith's decade-long investigation into the philosophical and metaphysical foundations of computation, artificial intelligence, and cognitive science. Based on a sustained critique of the formal tradition that underlies the reigning views, he presents an argument for an embedded, participatory, "irreductionist," metaphysical alternative. Smith seeks nothing less than to revise our understanding not only of the machines we build but also of the world with which they interact. Smith's ambitious project (...) begins as a search for a comprehensive theory of computation, able to do empirical justice to practice and conceptual justice to the computational theory of mind. A rigorous commitment to these two criteria ultimately leads him to recommend a radical overhaul of our traditional conception of metaphysics. Everything that exists - objects, properties, life, practice - lies Smith claims in the "middle distance," an intermediate realm of partial engagement with and partial separation from, the enveloping world. Patterns of separation and engagement are taken to underlie a single notion unifying representation and ontology: that of subjects' "registration" of the world around them. Along the way, Smith offers many fascinating ideas: the distinction between particularity and individuality, the methodological notion of an "inscription error," an argument that there are no individualswithin physics, various deconstructions of the type-instance distinction, an analysis of formality as overly disconnected ("discreteness run amok"), a conception of the boundaries of objects as properties of unruly interactions between objects and subjects, an argument for the theoretical centrality of reference preservation, and a theatrical, acrobatic metaphor for the contortions involved in the preservation of reference and resultant stabilization of objects. Sidebars and diagrams throughout the book help clarify and guide Smith's highly original and compelling argument. A Bradford Book. (shrink)

In this paper, we show that presentism -- the view that the way things are is the way things presently are -- is not undermined by the objection from being-supervenience. This objection claims, roughly, that presentism has trouble accounting for the truth-value of past-tense claims. Our demonstration amounts to the articulation and defence of a novel version of presentism. This is brute past presentism, according to which the truth-value of past-tense claims is determined by the past understood as a fundamental (...) aspect of reality different from things and how things are.

It is argued that propositions cannot be the compositional semantic values of sentences (in context) simply due to issues stemming from the compositional semantics of modal operators (or modal quantifiers). In particular, the fact that the arguments for double indexing generalize to multiple indexing exposes a fundamental tension in the default philosophical conception of semantic theory. This provides further motivation for making a distinction between two sentential semantic contents—what (Dummett 1973) called “ingredient sense” and “assertoric content”.
