This essay discusses how medieval authors from the thirteenth and fourteenth centuries dealt with a philosophical problem that social institutions pose for the Aristotelian dichotomy between natural and artificial entities. It is argued that marriage, political community, and language provided a particular challenge for the conception that things which are designed by human beings are artefacts. Medieval philosophers based their arguments for the naturalness of social institutions on the anthropological view that human beings are political animals by nature, but this (...) strategy required rethinking the borderline between nature and art. The limits of nature were extended, as social institutions were considered to be natural even though they are in many ways similar to artificial products. (shrink)

How is consciousness possible? What biological purpose does it serve? And why do we value it so highly? In Soul Dust, the psychologist Nicholas Humphrey, a leading figure in consciousness research, proposes a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us and makes us feel special and transcendent. Thus consciousness paves the way for spirituality, and allows (...) us, as human beings, to reap the rewards, and anxieties, of living in what Humphrey calls the "soul niche." Tightly argued, intellectually gripping, and a joy to read, Soul Dust provides answers to the deepest questions. It shows how the problem of consciousness merges with questions that obsess us all--how life should be lived and the fear of death. Resting firmly on neuroscience and evolutionary theory, and drawing a wealth of insights from philosophy and literature, Soul Dust is an uncompromising yet life-affirming work--one that never loses sight of the majesty and wonder of consciousness.

This article returns to Simone de Beauvoir’s philosophical oeuvre in order to offer a way of thinking beyond contemporary feminist divisions created by ‘gender critical’ or trans-exclusionary feminists. The ‘gender critical’ feminist position returns to sex essentialism to argue for ‘abolishing’ gender, while opponents often appeal to proliferated gender self-identities. I argue that neither goes far enough and that they both circumscribe utopian visions for a world beyond both sex and gender. I chart how Beauvoir’s ontological, ethical and political positions (...) can be used to overcome the material/cultural, sex/gender bind that the contemporary divide perpetuates. I outline Beauvoir’s ‘ambiguous’ non-foundational ontology that attends to both the cultural origins, and material effects, of both sex and gender, and to the extent that humyns are fundamentally social. After outlining Beauvoir’s definition of freedom as purposive action, I then outline how the existence of the humyn-made and intersubjectively-upheld ‘situations’ of both sex and gender delimit this, urging feminists to return to the lost question of eradicating both. I use the utopian impulse in Beauvoir to argue that an ethics of reciprocity is an alternative mode of understanding the self and others. Beauvoir also calls for a political strategy that I call a ‘utopian realism’ that I apply to the contemporary divide. A way forward that is attentive to the concerns of both positions is the pragmatic use of identity politics that is nonetheless mindful of identity’s limits, alongside Beauvoir’s proto-intersectional vision of solidarity politics based not on identity but on a position of alterity and shared political strategy. Ultimately, I use this to argue that feminism would do better to unite around a shared commitment to challenging alterity, rather than further contributing to it. (shrink)

This book provides extensive and critical engagement with some of the most recent and compelling arguments favoring abortion choice. It features original essays from leading and emerging philosophers, bioethicists and medical professionals that present philosophically sophisticated and novel arguments against abortion choice. The chapters in this book are divided into three thematic sections. The first set of essays focuses primarily on unborn human individuals--zygotes, embryos and fetuses. In these chapters it is argued, for example, that human organisms begin to exist (...) at conception and that zygotes, embryos and fetuses are persons. These chapters also explore questions about whether or not zygotes, embryos and fetuses are part of their mothers' bodies. The second set of essays focuses primarily on elective abortion and the debates surrounding it. These chapters consider whether or not opponents of abortion are commonly hypocritical, how opponents of abortion should think about adoption, how emerging technologies may affect the current debate and whether or not those participating in the debate should rely on analogies to support their case. Finally, the third set of essays shifts focus from the legal and moral status of elective abortion to its place in medical practice. In these chapters it is argued that elective abortion embodies a kind of ableism, and that elective abortion is medically unnecessary, harmful to women's mental health and that telemedicine abortion poses significant risks to women's health. Agency, Pregnancy and Persons offers an up-to-date examination of unborn human beings, the debates surrounding elective abortion and the place of elective abortion within medical practice. It will be of interest to medical professionals and those who work in philosophy, bioethics and medical ethics alike. (shrink)

A many-valued (aka multiple- or multi-valued) semantics, in the strict sense, is one which employs more than two truth values; in the loose sense it is one which countenances more than two truth statuses. So if, for example, we say that there are only two truth values—True and False—but allow that as well as possessing the value True and possessing the value False, propositions may also have a third truth status—possessing neither truth value—then we have a many-valued semantics in the (...) loose but not the strict sense. A many-valued logic is one which arises from a many-valued semantics and does not also arise from any two-valued semantics [Malinowski, 1993, 30]. By a ‘logic’ here we mean either a set of tautologies, or a consequence relation. We can best explain these ideas by considering the case of classical propositional logic. The language contains the usual basic symbols (propositional constants p, q, r, . . .; connectives ¬, ∧, ∨, →, ↔; and parentheses) and well-formed formulas are defined in the standard way. With the language thus specified—as a set of well-formed formulas—its semantics is then given in three parts. (i) A model of a logical language consists in a free assignment of semantic values to basic items of the non-logical vocabulary. Here the basic items of the non-logical vocabulary are the propositional constants. The appropriate kind of semantic value for a proposition is a truth value, and so a model of the language consists in a free assignment of truth values to basic propositions. Two truth values are countenanced: 1 (representing truth) and 0 (representing falsity). (ii) Rules are presented which determine a truth value for every proposition of the language, given a model. The most common way of presenting these rules is via truth tables (Figure 1). Another way of stating such rules—which will be useful below—is first to introduce functions on the truth values themselves: a unary function ¬ and four binary functions ∧, ∨, → and ↔ (Figure 2)..

The two great philosophical figures at the culminating point of the Enlightenment are Thomas Reid in Scotland and Immanuel Kant in Germany. Reid was by far the most influential across Europe and the United States well into the nineteenth century. Since that time his fame and influence have been eclipsed by his German contemporary. This important book by one of today's leading philosophers of knowledge and religion will do much to reestablish the significance of Reid for philosophy today. Nicholas (...) Wolterstorff has produced the first systematic account of Reid's epistemology. Relating Reid's philosophy to present-day epistemological discussions the author demonstrates how they are at once remarkably timely, relevant, and provocative. No other book both uncovers the deep pattern of Reid's thought and relates it to contemporary philosophical debate. This book should be read by historians of philosophy as well as all philosophers concerned with epistemology and the philosophy of mind. (shrink)

Presumption is a remarkably versatile and pervasively useful resource. Firmly grounded in the law of evidence from its origins in classical antiquity, it made its way in the days of medieval scholasticism into the theory and practice of disputation and debate. Subsequently, it extended its reach to play an increasingly significant role in the philosophical theory of knowledge. It has thus come to represent a region where lawyers, debaters, and philosophers can all find some common around. In Presumption and the (...) Practices of Tentative Cognition, Nicholas Rescher endeavors to show that the process of presumption plays a role of virtually indispensable utility in matters of rational inquiry and communication. The origins of presumption may lie in law, but its importance is reinforced by its service to the theory of information management and philosophy. (shrink)

Human beings engage works of the arts in many different ways: they sing songs while working, they kiss icons, they create and dedicate memorials. Yet almost all philosophers of art of the modern period have ignored this variety and focused entirely on just one mode of engagement, namely, disinterested attention. Nicholas Wolterstorff asks why this might be, and proposes that almost all philosophers have accepted the grand narrative concerning art in the modern world. It is generally agreed that in (...) the early modern period, members of the middle class in Western Europe increasingly engaged works of the arts as objects of disinterested attention. The grand narrative claims that this change represented the arts coming into their own, and that works of art, so engaged, are socially other and transcendent. Wolterstorff rejects this claim, and offers an alternative framework for thinking about the arts. Central to his alternative framework are the idea of the arts as social practices and the idea of works of the arts as having different meaning in different practices. (shrink)

What is the function of morality? On this question, something approaching a consensus has recently emerged. Impressed by developments in evolutionary theory, many philosophers now tell us that the function of morality is to reduce social tensions, and to thereby enable a society to efficiently promote the well-being of its members. In this paper, I subject this consensus to rigorous scrutiny, arguing that the functional hypothesis in question is not well supported. In particular, I attack the supposed evidential relation between (...) an evolutionary genealogy of morals and the functional hypothesis itself. I show that there are a great many functionally relevant discontinuities between our own culture and the culture within which morality allegedly emerged, and I argue that this seriously weakens the inference from morality’s evolutionary history to its present-day function.

Moral identity and moral dissonance in business ethics have explored tensions relating to moral self-identity and the pressures for identity compartmentalization in the workplace. Yet, the connection between these streams of scholarship, spirituality at work, and business ethics is under-theorized. In this paper, we examine the Quaker tradition to explore how Quakers’ interpret moral identity and negotiate the moral dissonance associated with a divided self in work organizations. Specifically, our study illuminates that while Quakers’ share a tradition-specific conception of “Quaker (...) morality” grounded in Quaker theology and the Quaker testimonies to truth, integrity, peace, equality, and simplicity, they often foreground the pursuit of an undivided self through seeking work that enables an expression of Quaker moral identity, or by resigning from work organizations that do not. In most cases, however, Quakers’ face moral dissonance at work and engage in either identity compartmentalization and draw upon the metaphor of a ‘spiritual journey’ as a form of self-justification, or reframe, compartmentalize and engage in work tasks that are both subjectively moral and meaningful. We present a model that elaborates these negotiation processes and invite further research that examines how the spiritual traditions influence moral identity construction at work. (shrink)

There is an extensive literature on time travel in both philosophy and physics. Part of the great interest of the topic stems from the fact that reasons have been given both for thinking that time travel is physically possible—and for thinking that it is logically impossible! This entry deals primarily with philosophical issues; issues related to the physics of time travel are covered in the separate entries on time travel and modern physics and time machines. We begin with the definitional (...) question: what is time travel? We then turn to the major objection to the possibility of backwards time travel: the Grandfather paradox. Next, issues concerning causation are discussed—and then, issues in the metaphysics of time and change. We end with a discussion of the question why, if backwards time travel will ever occur, we have not been visited by time travellers from the future. (shrink)

The authors explore the history of experiments in economics, provide examples of different types of experiments and show that the growing use of experimental methods is transforming economics into an empirical science.

Anti-war pacifism eschews modern war as a means of attaining peace. It holds war to be not only evil and supremely harmful, but also, on balance, morally wrong. But what about force short of war? The aim of this paper is to analyse targeted killing, a specific form of force short of war, from an anti-war pacifist perspective, or, more specifically, from two related but distinct pacifist perspectives: conditional and contingent. Conditional pacifism deems war to be unjustified if the condition (...) that innocent persons are killed in war is satisfied. Since this condition is always fulfilled, conditional pacifism implies the impermissibility of modern war. Contingent pacifism concedes that war would be morally acceptable if its harms were sufficiently outweighed by its benefits, but maintains that no (or very few) wars meet this criterion. The empirical reality of war is such that it cannot be justified, because it harms too many innocents in proportion to the harm it prevents. Pacifists’ treatment of targeted killing short of war should thus concentrate on the harm it does to innocents. Conditional pacifists should focus on whether targeted killing kills innocents, while contingent pacifists should focus on whether the harm it does to innocents is disproportionate to its benefits.

Here, I combine the semantics of Mares and Goldblatt [20] and Seki [29, 30] to develop a semantics for quantified modal relevant logics extending ${\bf B}$. The combination requires demonstrating that the Mares–Goldblatt approach is apt for quantified extensions of ${\bf B}$ and other relevant logics, but no significant bridging principles are needed. The result is a single semantic approach for quantified modal relevant logics. Within this framework, I discuss the requirements a quantified modal relevant logic must satisfy to be (...) “sufficiently classical” in its modal fragment, where frame conditions are given that work for positive fragments of logics. The roles of the Barcan formula and its converse are also investigated. (shrink)

Translation of the genetic code occurs in a cycle where ribosomes engage mRNAs, synthesize protein, and then disengage in order to repeat the process again. The final part of this process—ribosome recycling, where ribosomes dissociate from mRNAs—involves a complex molecular choreography of specific protein factors to remove the large and small subunits of the ribosome in a coordinated fashion. Errors in this process can lead to the accumulation of ribosomes at stop codons or translation of downstream open reading frames (ORFs). (...) Ribosome recycling is also critical when a ribosome stalls during the elongation phase of translation and must be rescued to allow continued translation of the mRNA. Here we discuss the molecular interactions that drive ribosome recycling, and their regulation in the cell. We also examine the consequences of inefficient recycling with regards to disease, and its functional roles in synthesis of novel peptides, regulation of gene expression, and control of mRNA‐associated proteins. Alterations in ribosome recycling efficiency have the potential to impact many cellular functions but additional work is needed to understand how this regulatory power is utilized. (shrink)

A philosophical treatment of the idea of authority, this book is a dialogue between three characters. "Director," a philosopher, challenges the others to think through their ideas of authority, how it is established, how it works, and how it can be either subtle or bold.

The aim of the Schematism chapter of the Critique of Pure Reason is to solve the problem posed by the “inhomogeneity” of intuitions and categories: the sensible properties of objects represented in intuition are of a different kind than the properties represented by categories. Kant's solution is to introduce what he calls “transcendental schemata,” which mediate the subsumption of objects under categories. I reconstruct Kant's solution in terms of two substantive premises, which I call Subsumption Sufficiency (i.e., that subsuming an (...) object under a transcendental schema is sufficient to subsume it under the corresponding category) and Real Possibility (i.e., that it is really possible to subsume objects under each of the transcendental schemata). These two principles, together with a trivial modal one (the Subsumption-Possibility Link), entail that it is possible to subsume objects under categories; in other words, the argument of the Schematism is valid. The main work of the paper consists in reconstructing Kant's arguments for, and explanations of, these premises. I argue that they hinge on Kant's claim that transcendental schemata are “time-determinations,” which I interpret to mean: rules for reflexively representing the temporal relations among our own representational states. On the basis of this reading, I reconstruct Kant's argument for Subsumption Sufficiency, category by category. I also explain why Real Possibility follows almost immediately. Granting Kant the argument up to this point in the Critique, the argument of the Schematism is sound. (shrink)

The experience of having to suffer debilitating pain is far too common in the United States, and many patients continue to be inadequately treated by their doctors. Although many physicians freely admit that their pain management practices may have been somewhat lacking, many more express concern that the prescribing of heightened levels of opioid analgesics may result in closer regulatory scrutiny, criminal investigation, or even criminal prosecution.Although several researchers have examined the regulatory environment and the threat of sanction or harm (...) it poses to physicians and patients, few have examined the likelihood of investigation or prosecution stemming from the aggressive use of opioids in physician-directed pain management. Accordingly, in an effort to assess whether the fear of prosecution is realistic and, if so, what factors contribute to its likelihood, we surveyed chief prosecutors in four states about their knowledge, opinions, and attitudes concerning opioids and the prosecution of physicians stemming from the treatment of patients who were either terminally ill or suffering from chronic noncancer pain.

Recent attempts to distinguish a normatively acceptable “civic nationalism"—as distinct from an irrationally tainted “ethnic nationalism"—have failed to take seriously the implications of the transition from the city as the immediate spatial unit of the patria to the more abstract national state that replaced it. The nation‐state has required a mythologizing naturalism to legitimate it, thus blurring the distinction between “civic” and “ethnic.” The urban political experience of the patria is lost to us; cosmopolitan intellectuals should resist the comforting temptation (...) to recover it in the nation, and should recognize civic nationalism for the oxymoron it is.

A Review of Lindsay Judson and Vassilis Karasmanis , Remembering Socrates: Philosophical Essays, Clarendon Press, Oxford, 2006.

This chapter analyses how one thirteenth century Parisian philosopher, Nicholas of Vaudémont (fl. 1370s), understood the tension between the common good in the sense of the good of the community as a whole, and individual good in his commentary of Aristotle’s Politics. The analysis proceeds in relation to two of Nicholas’ questions. The first of them concerns the classical problem of whether or not a virtuous person should sacrifice his life for the sake of his community; and the (...) second question is related to the justification of capital punishment for the sake of the common good. It is claimed that Nicholas entertains at least a theoretical possibility that virtuous action may not necessarily entail the common good and that he further distinguishes the concern for the common good from the private sphere by arguing that responsibility of the common good rests solely with the political ruler. As a result, the tension becomes a fracture as the theoretical distance between the good of an individual and the common good widens. (shrink)

The Gorgias ends with Socrates telling an eschatological myth that he insists is a rational account and no mere tale. Using this story, Socrates reasserts the central lessons of the previous discussion. However, it isn’t clear how this story can persuade any of the characters in the dialogue. Those (such as Socrates) who already believe the underlying philosophical lessons don’t appear to require the myth, and those (such as Callicles) who reject these teachings are unlikely to be moved by this (...) far-fetched tale. This raises the question of who the myth is told for and what function it is meant to serve. This chapter argues that the myth is aimed, not at Callicles, but Socrates and those who aspire to follow him. There are uncertainties about the philosophical life that are due to the nature of embodiment, as well as reasons to doubt the connection between happiness and virtue. The myth assists with the former by presenting an image that draws a philosopher away from the goods of the body toward the goods of the soul. The story assists with the latter by presenting an image of cosmic justice, thereby securing happiness in proportion to virtue. (shrink)

Unlike almost all other philosophers of science, Karl Popper sought to contribute to natural philosophy or cosmology – a synthesis of science and philosophy. I consider his contributions to the philosophy of science and quantum theory in this light. There is, however, a paradox. Popper’s most famous contribution – his principle of demarcation – in driving a wedge between science and metaphysics, serves to undermine the very thing he professes to love: natural philosophy. I argue that Popper’s philosophy of science (...) is, in this respect, defective. Science cannot proceed without making highly problematic metaphysical assumptions concerning the comprehensibility and knowability of the universe. Precisely because these assumptions are problematic, rigour requires that they be subjected to sustained critical scrutiny, as an integral part of science itself. Popper’s principle of demarcation must be rejected. Metaphysics and philosophy of science become a vital part of science. Natural philosophy is reborn. A solution to the problem of what it means to say a theory is unified is proposed, a problem Popper failed to solve. In The Logic of Scientific Discovery, Popper made important contributions to the interpretation of quantum theory, especially in connection with Heisenberg's uncertainty relations. Popper's advocacy of natural philosophy has important implications for education. (shrink)

PROBLEM: THE BEING OF NONEXISTENTS. In matters of irreality, medieval philosophers were not much concerned with fiction as such. The prime focus of their attention was theology, and their dealings with nonexistence related to the role of such items in relation to the thoughts of God rather than those of man. In this light, the medievals approached the issue of nonexistents on essentially the following basis.

This book is an original—the first-ever treatment of the mathematics of Luck. Setting out from the principle that luck can be measured by the gap between reasonable expectation and eventual realization, the book develops step-by-step a mathematical theory that accommodates the entire range of our pre-systematic understanding of the way in which luck functions in human affairs. In so moving from explanatory exposition to mathematical treatment, the book provides a clear and accessible account of the way in which luck assessment (...) enters into the calculations of rational decision theory.

Apart from its foray into technical issues of risk assessment and management, this book has one principal aim. With situations of chancy outcomes certain key factors—including outcome possibilities, overall expectation, threat, and even luck—are measurable parameters. But risk is something different: it is not measurable a single parametric quantity, but a many-sided factor that has several different components, and constitutes a complex phenomenon that must be assessed judgmentally in a highly contextualized way. This book explains and analyzes how this works (...) out in practice. Topics in this work include choice and risk, chance and likelihood, as well as outcome-yield evaluation and risk. It takes into account abnormal situations and eccentric measurements, situational evaluation and expectation and scrutinizes the social aspect of risk. The book is of interest to logicians, philosophers of mathematics, and researchers of risk assessment. The project is a companion piece to the author's LUCK THEORY, also published by Springer.

The paper is a critical analysis of Paul Ricoeur’s philosophy of work as it is formulated in a number of essays from the 1950s and 60s. It begins with a reconstruction of the central theses advanced in ‘Travail et parole’ (1953) and related texts, where Ricoeur sought to outline a philosophical anthropology in which work is given its due. To give work its due, from an anthropological standpoint, is to see it as limited by counter-concept of language, according to Ricoeur. (...) The paper then argues that this way of understanding the anthropological significance of work is not only internally problematic, but at odds with phenomenological insights to be found elsewhere in Ricoeur’s oeuvre, particularly Le Volontaire et l’involontaire (1950). The final section of the paper makes some suggestions for how the phenomenological and anthropological poles of a philosophy of work might be better integrated, and the ‘nexus between speech and work’ better described.

This article seeks to explore the metaphor ‘darkness and light’ and its relevance to education through hauntological study. It draws on the ideas of Derrida and Fisher to reveal that the metaphor functions in binary form and holds significations of truth, goodness and knowledge to subordinate oppositional ideas of darkness. Despite the everyday usage of this metaphor, the subordination of darkness is shown to be less positive than it would appear. Darkness and light also shows itself to be an archetypal (...) metaphor, meaning that it is founded in our depth-experiences of the world and is applicable in many varied contexts, therefore granting it a power to remain in everyday usage. The archetypal nature of this metaphor is uncovered through its utilisation in Plato’s ‘Allegory of the Cave’, thus opening a discussion about how it continues to haunt education today. Broadly, it is the faith in the supposed betterment available through education that is exposed. Finally, in a Derridean manner, this article explores how the metaphor of darkness and light could be overturned in relation to education, thus destabilising a foundational metaphor on which education currently lies.

Given the growing prominence of nudge economics both within and beyond the academy, it is a timely moment to reassess the philosophical and political arguments that sit at its core, and in particular what Richard Thaler and Cass Sunstein call libertarian paternalism. The first half of this paper provides a detailed account of the main features of this form of paternalism, before moving, in the second half, to a critical evaluation of the nudge agenda that questions, among other things, the (...) gendered basis of paternalistic governance; the idea of ‘nudging for good’; and the political values that underpin nudge. The final section of this paper builds on the existing work of John McMahon by asking whether libertarian paternalism should be understood as a new, hybrid form of neoliberalism, or, rather, as a post-neoliberal form of governance that has emerged out of, and flourished in, the post-crisis situation.

This paper argues that recognition is, fundamentally, a relationship between a person and a reason. The recognizer acts for a reason, in the interpersonal case, only when she takes the recognizee’s rational intentions—intentions whose content is favored by reasons—as reasons. Free agency, on this view, is a rational power to act for reasons: the recognizer’s disposition to take the recognizee’s rational intentions as reasons across relevant possible worlds in which she forms these intentions. On the basis of this generic account (...) of free agency, I argue that free productive agency is a rational power to produce for reasons: the recognizer’s disposition to take the rational productive intentions of the recognizee as reasons across relevant possible worlds in which she forms these intentions. But capitalism makes it impossible to satisfy this requirement, for it subjects the taking of reasons to the realization of profit. So capitalism makes capitalist and worker unfree and the realization of free productive agency impossible. (shrink)

It has been argued that alethic pluralists -- who hold that there are several distinct truth properties -- face a problem when it comes to defining validity. Via consideration of the classical concept of logical consequence, and of strategies for defining validity in many-valued logics, this paper proposes two new kinds of solution to the problem.

The question of whether it is permissible to quantify into a modal context is re-examined from an empiricist perspective. Following Wiggins, it is argued that an ontology of continuants implies essentialism, but it is also argued, against Wiggins, that the only conception of necessity that we need to start out with is that of analyticity. Essentialism, of a limited kind, can then be actually generated from this. An exceptionally fine-grained identity criterion for continuants is defended in this context. The debate (...) between Wiggins and Ayer over the legitimacy of de re modality is then examined in the light of these results, and it is argued that my position is consistent with Ayer’s minimalist assumptions. It is also argued that non-continuants will not sustain the essential/accidental distinction, thus giving some concessions to the sceptics. It is also shown that there are close connections between these issues and the more modern two-dimensionalist way of disentangling the necessary from the a posteriori, and that the latter needs to learn from the former.
