Niels Bohr famously argued that a consistent understanding of quantum mechanics requires a new epistemic framework, which he named complementarity . This position asserts that even in the context of quantum theory, classical concepts must be used to understand and communicate measurement results. The apparent conflict between certain classical descriptions is avoided by recognizing that their application now crucially depends on the measurement context. ;Recently it has been argued that a new form of complementarity can provide a solution to the (...) so-called information loss paradox. Stephen Hawking argues that the evolution of black holes cannot be described by standard unitary quantum evolution, because such evolution always preserves information, while the evaporation of a black hole will imply that any information that fell into it is irrevocably lost---hence a "paradox." Some researchers in quantum gravity have argued that this paradox can be resolved if one interprets certain seemingly incompatible descriptions of events around black holes as instead being complementary. ;In this dissertation I assess the extent to which this black hole complementarity can be undergirded by Bohr's account of the limitations of classical concepts. I begin by offering an interpretation of Bohr's complementarity and the role that it plays in his philosophy of quantum theory. After clarifying the nature of classical concepts, I offer an account of the limitations these concepts face, and argue that Bohr's appeal to disturbance is best understood as referring to these conceptual limits. ;Following preparatory chapters on issues in quantum field theory and black hole mechanics, I offer an analysis of the information loss paradox and various responses to it. I consider the three most prominent accounts of black hole complementarity and argue that they fail to offer sufficient justification for the proposed incompatibility between descriptions. ;The lesson that emerges from this dissertation is that we have as much to learn from the limitations facing our scientific descriptions as we do from the successes they enjoy. Because all of our scientific theories offer at best limited, effective accounts of the world, an important part of our interpretive efforts will be assessing the borders of these domains of description.

We present a formal semantics for epistemic logic, capturing the notion of knowability relative to information (KRI). Like Dretske, we move from the platitude that what an agent can know depends on her (empirical) information. We treat operators of the form K_AB (‘B is knowable on the basis of information A’) as variably strict quantifiers over worlds with a topic- or aboutness- preservation constraint. Variable strictness models the non-monotonicity of knowledge acquisition while allowing knowledge to be intrinsically stable. Aboutness-preservation models (...) the topic-sensitivity of information, allowing us to invalidate controversial forms of epistemic closure while validating less controversial ones. Thus, unlike the standard modal framework for epistemic logic, KRI accommodates plausible approaches to the Kripke-Harman dogmatism paradox, which bear on non-monotonicity, or on topic-sensitivity. KRI also strikes a better balance between agent idealization and a non-trivial logic of knowledge ascriptions. (shrink)

Dr. Stephen Hawking was the most renowned scientist since Einstein, known both for his groundbreaking work in physics and cosmology and for his mischievous sense of humor. He educated millions of readers about the origins of the universe and the nature of black holes, and inspired millions more by defying a terrifying early prognosis of ALS, which originally gave him only two years to live. In later life he could communicate only by using a few facial muscles, but he continued (...) to advance his field and serve as a revered voice on social and humanitarian issues. Hawking not only unraveled some of the universe's greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history. Featuring a foreword by Eddie Redmayne, who won an Oscar playing Stephen Hawking, an introduction by Nobel Laureate Kip Thorne, and an afterword from Hawking's daughter, Lucy. (shrink)

Online supplement, "Mulsow: Additions to Notes drawn from the 2002 edition of Moderne aus dem Untergrund" full versions of nearly 300 notes that were truncated in the print edition. Hosted on H. C. Erik Midelfort's website. Martin Mulsow's seismic reinterpretation of the origins of the Enlightenment in Germany won awards and renown in its original German edition, and now H. C. Erik Midelfort's translation makes this sensational book available to English-speaking readers. In Enlightenment Underground, Mulsow shows that even in the (...) late seventeenth century some thinkers in Germany ventured to express extremely dangerous ideas, but did so as part of a secret underground. Scouring manuscript collections across northern Europe, Mulsow studied the writings of countless hitherto unknown radical jurists, theologians, historians, and dissident students who pushed for the secularization of legal, political, social, and religious knowledge. Often their works circulated in manuscript, anonymously, or as clandestinely published books. Working as a philosophical microhistorian, Mulsow has discovered the identities of several covert radicals and linked them to circles of young German scholars, many of whom were connected with the vibrant radical cultures of the Netherlands, England, and Denmark. The author reveals how radical ideas and contributions to intellectual doubt came from Socinians and Jews, church historians and biblical scholars, political theorists, and unemployed university students. He shows that misreadings of humorous or ironic works sometimes gave rise to unintended skeptical thoughts or corrosively political interpretations of Christianity. This landmark book overturns stereotypical views of the early Enlightenment in Germany as cautious, conservative, and moderate, and replaces them with a new portrait that reveals a movement far more radical, unintended, and puzzling than previously suspected.

What does ‘Smith knows that it might be raining’ mean? Expressivism here faces a challenge, as its basic forms entail a pernicious type of transparency, according to which ‘Smith knows that it might be raining’ is equivalent to ‘it is consistent with everything that Smith knows that it is raining’ or ‘Smith doesn’t know that it isn’t raining’. Pernicious transparency has direct counterexamples and undermines vanilla principles of epistemic logic, such as that knowledge entails true belief and that something can (...) be true without one knowing it might be. I re-frame the challenge in precise terms and propose a novel expressivist formal semantics that meets it by exploiting (i) the topic-sensitivity and fragmentation of knowledge and belief states and (ii) the apparent context-sensitivity of epistemic modality. The resulting form of assertibility semantics advances the state of the art for state-based bilateral semantics by combining attitude reports with context-sensitive modal claims, while evading various objectionable features. In appendices, I compare the proposed system to Beddor and Goldstein’s ‘safety semantics’ and discuss its analysis of a modal Gettier case due to Moss. (shrink)

I construe Relevant Alternatives Theory (RAT) as an abstract combination of anti-skepticism and epistemic modesty, then re-evaluate the challenge posed to it by the missed clue counter-examples of Schaffer [2001]. The import of this challenge has been underestimated, as Schaffer’s specific argument invites distracting objections. I offer a novel formalization of RAT, accommodating a suitably wide class of concrete theories of knowledge. Then, I introduce abstract missed clue cases and prove that every RA theory, as formalized, admits such a case. (...) This yields an argument - in Schaffer’s spirit - that resists easy dismissal.

The goal of the current paper is to provide an introduction to and survey of the diverse landscape of relevant alternatives theories of knowledge. Emphasis is placed throughout both on the abstractness of the relevant alternatives approach and its amenability to formalization through logical techniques. We present some of the important motivations for adopting the relevant alternatives approach; briefly explore the connections and contrasts between the relevant alternatives approach and related developments in logic, epistemology and philosophy of science; provide a (...) schema for classifying and studying relevant alternatives theories at different levels of abstraction; and present a sample of relevant alternatives theories (contrasting what we call question-first and topic-first theories) that tie our discussion to on-going debates in the philosophical literature, as well as showcasing techniques for formalizing some of the important positions in these debates.

L’addition, dans la cinquième édition en 1683 de La Logique ou L’Art de penser, d’un chapitre consacré à la définition générale du signe et de plusieurs chapitres relevant spécifiquement d’une analyse des signes linguistiques, a été parfois interprétée comme une apparition tardive du “problème du langage” dans le traité d’Arnauld et Nicole. Parce que la plupart de ces chapitres supplémentaires sont la transposition de passages auparavant destinés dans la Perpétuité de la foi (1669-1674) à réfuter le sens calviniste de Ceci (...) est mon corps, on a été enclin à attribuer l’importance de la question du signe et du “problème du langage” dans l’édition de 1683 à une origine théologique. J’essaie au contraire de montrer que, dès la première édition de L’Art de penser en 1662, la problématisation des écarts des expressions linguistiques avec une correspondance terme à terme entre les mots et les idées a été indissociable pour Port-Royal de l’analyse des opérations de l’esprit. Selon moi, dans la Perpétuité de la foi, la critique du sens calviniste de la formule eucharistique constitue elle-même une application de cette analyse logique du langage : les passages incorporés ensuite dans L’Art de penser sont dans le prolongement des réflexions de 1662 sur les difficultés d’adéquation entre le dire et le vouloir-dire. Je montre pour finir que la définition générale du signe à Port-Royal suppose une restructuration de la définition augustinienne du De doctrina christiana, et fonde en 1683 une identification de la relation de signification linguistique à un rapport de représentation des mots aux idées, qui vient redoubler le rapport de représentation des idées aux choses établi en 1662.

A Brief History of Time: From the Big Bang to Black Holes is a popular-science book on cosmology (the study of the origin and evolution of the universe) by British physicist Stephen Hawking. It was first published in 1988. Hawking wrote the book for readers who have no prior knowledge of the universe and people who are interested in learning.

Many philosophers and psychologists argue that out everyday ability to predict and explain the actions and mental states of others is grounded in out possession of a primitive 'folk' psychological theory. Recently however, this theory has come under challenge from the simulation alternative. This alternative view says that human beings are able to predict and explain each other's actions by using the resources of their own minds to simulate the psychological aetiology of the actions of the others. This book and (...) the companion volume Folk Psychology: The Theory of Mind Debate together offer a richly woven fabric of philosophical and psychological theory, which promises to yield real insights into the nature of our mental lives.

Of course, although this view on meaning was the prevailing one for almost a century, many of the people who initiated the enterprise of logical semantics, including people like Frege and Wittgenstein, had an open eye for all that it did not catch. However, the logical means which Frege, Wittgenstein, Russell, and the generation that succeeded them, had at their disposal were those of classical mathematical logic and set-theory, and these indeed are not very suited for an analysis of other (...) aspects of meaning than those which the slogan covers. A real change in view then had to await the emergence of other concepts, which in due course became available mainly under the influence of developments in computer science and cognate disciplines such as artificial intelligence. And this is one of the reasons why it took almost a century before any serious and successful challenge of the view that meaning equals truthconditions from within logical semantics could emerge.

When one thinks—knows, believes, imagines—that something is the case, one’s thought has a topic: it is about something, towards which one’s mind is directed. What is the logic of thought, so understood? This book begins to explore the idea that, to answer the question, we should take topics seriously. It proposes a hyperintensional account of the propositional contents of thought, arguing that these are individuated not only by the set of possible worlds at which they are true, but also by (...) their topic: what they are about. The book then builds epistemic, doxastic, probabilistic, and conditional logics based on this view. It applies them to issues ranging from dogmatism, scepticism, and epistemic fallibilism, to imagination and suppositional reasoning, belief revision, framing effects, and the acceptability of indicative conditionals.

This book explores a question central to philosophy--namely, what does it take for a belief to be justified or rational? According to a widespread view, whether one has justification for believing a proposition is determined by how probable that proposition is, given one's evidence. In this book this view is rejected and replaced with another: in order for one to have justification for believing a proposition, one's evidence must normically support it--roughly, one's evidence must make the falsity of that proposition (...) abnormal in the sense of calling for special, independent explanation. This conception of justification bears upon a range of topics in epistemology and beyond. Ultimately, this way of looking at justification guides us to a new, unfamiliar picture of how we should respond to our evidence and manage our own fallibility. This picture is developed here.

My topic is moderate modal skepticism in the spirit of Peter van Inwagen. Here understood, this is a conservative version of modal empiricism that severely limits the extent to which an ordinary agent can reasonably believe “exotic” possibility claims. I offer a novel argument in support of this brand of skepticism: modal skepticism grounds an attractive (and novel) reply to Humean skepticism. Thus, I propose that modal skepticism be accepted on the basis of its theoretical utility as a tool for (...) dissolving philosophical paradox. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.1 (2001) 141-160 [Access article in PDF] The Politics of Character in John Milton's Divorce Tracts David Hawkes nunquam privatum esse sapientum --Cicero I. There has recently been a great deal of debate over the relative influence on Milton's politics of two discordant revolutionary ideologies: classical republicanism and radical Protestant theology. 1 In the mid-seventeenth century the search for intellectual precedents and (...) rationalizations of the English revolution brought these two traditions into an uneasy alliance, and Milton, like many other revolutionary apologists, drew on both of them. Of course the two schools of thought are not necessarily incompatible. J. G. A. Pocock notes one point of connection between them: The context in which men attain their final end--or recover their prima forma, though this concept might not have been antinomian enough for the radical saints of the New Model--is that of apocalypse; the "end" of Aristotelian teleology is still united with the eschatological "end" of prophetic time. 2The Aristotelian "end" of man is the good, defined as "an activity of soul in accordance with virtue," and the belief that one can or has fulfilled that end is [End Page 141] certainly amenable to Protestant antinomianism. 3 Furthermore, as Sharon Achinstein points out, Milton's "conception of virtue... melds the religious notion of conscience with a classical sense of civic duty." 4 On the other hand there are significant differences between the classical and the Christian notions of "virtue" and the "good," which dictate that, as Nigel Smith puts it, "[c]lassical republicanism, properly conceived, would in many ways be in conflict with the millenarian, chiliastic and perfectionist Protestantism of the sects." 5 The problem faced by Milton as a Protestant Republican is that the definition of the "good" offered by millennial sanctification and that attainable through Aristotelian virtue are in many ways mutually exclusive and contradictory. They have been characterized as such ever since Augustine's City of God asserted that pagan ethics are incompatible with true, Christian virtue. 6 Millennialism relies on faith; civic humanist virtue relies on works. Antinomianism abolishes the law; republicanism institutes the rule of law. The saints are sanctified by grace; the virtuous are distinguished by their own strength of character. Radical Protestant freedom is negative and private--it is the ability to speak and worship according to the dictates of conscience; civic humanist liberty is positive and public, the ability to participate fully in the government of the res publica. While daunting, however, these contradictions are not quite insuperable. I believe that Milton finds a common denominator in the accounts given by these two traditions of psychological objectification and that the agreement of Roman and Christian morality on this point leads him to make the tendency to objectification (or rather the ability to resist that tendency) the central issue of his mature political theory.The political ideas of the classical republicans and their descendants, the Renaissance civic humanists, were based upon Aristotle's Politics and Nico-machean Ethics, while the intellectual sources of radical Protestantism can be traced to Luther's commentaries on Paul's epistles. During the English revolution the Pauline exegesis of the relationship between the old and the new covenants provided intellectual ammunition against custom and tradition, as well as inspiring the antinomianism of the radical fringe to which Milton was falsely accused of adhering during the divorce controversy. In the divorce tracts Milton points out that Aristotle and Paul share one fundamental tenet: they argue that interior and exterior slavery are of the same nature and therefore concomitant [End Page 142] and inseparable. Furthermore, Milton notes, Aristotle and Paul both claim that exterior and interior slavery consist in "carnality," the subjection of the spirit to the flesh. This identification of carnality with servility becomes a constant strain which runs throughout Milton's career and provides the consistent element in his apparently vacillating theories of politics and religion.II. Although this argument recurs throughout Milton's career, it is first hammered into shape during the divorce controversy... (shrink)

In this paper I propose a new solution to the problem of change: situationalism. According to this view, parts of reality fundamentally disagree about what is the case and reality as a whole is unsettled (i.e. metaphysically indeterminate). When something changes, parts of the world irreconcilably disagree about what properties it has. From this irreconcilable disagreement, indeterminacy arises. I develop this picture using situations, which are parts of possible worlds; this gives it the name situationalism. It allows a B-theory endurance (...) view on which there is genuine incompatibility when things change. There are costs to the view, which are explored, but it is a novel approach which offers a distinct explanation of what happens when things exist through change. (shrink)

. Science at the interface with society is regarded with mistrust among parts of the public. Scientific judgments on matters of practical concern are not infrequently suspected of being incompetent and biased. I discuss two proposals for remedying this deficiency. The first aims at strengthening the independence of science and suggests increasing the distance to political and economic powers. The drawback is that this runs the risk of locking science in an academic ivory tower. The second proposal favors “counter-politicization” in (...) that research is strongly focused on projects “in the public interest,” that is, on projects whose expected results will benefit all those concerned by these results. The disadvantage is that the future use of research findings cannot be delineated reliably in advance. I argue that the underlying problem is the perceived lack of relevance and reliability and that pluralism is an important step toward its solution. Pluralism serves to stimulate a more inclusive research agenda and strengthens the well-testedness of scientific approaches. However, pluralism also prevents the emergence of clear-cut practical suggestions. Accordingly, pluralism is part of the solution to the credibility crisis of science, but also part of the problem. In order for science to be suitable as a guide for practice, the leeway of scientific options needs to be narrowed – in spite of uncertainty in epistemic respect. This reduction can be achieved by appeal to criteria that do not focus on the epistemic credentials of the suggestions but on their appropriateness in practical respect. (shrink)

Divided into four parts, this treatise begins with well-known criticisms of nonreligious ethics and then develops an atheistic metaethics. In Part 2, Martin criticizes the Christian foundation of ethics, specifically the ’divine command theory’ and the idea of imitating the life of Jesus as the basis of Christian morality. Part 3 demonstrates that life can be meaningful in the absence of religious belief. Part 4 criticizes the theistic point of view in general terms as well as the specific Christian doctrines (...) of the atonement, salvation, and the resurrection. (publisher, edited). (shrink)

We propose a solution to the problem of logical omniscience in what we take to be its fundamental version: as concerning arbitrary agents and the knowledge attitude per se. Our logic of knowledge is a spin-off from a general theory of thick content, whereby the content of a sentence has two components: an intension, taking care of truth conditions; and a topic, taking care of subject matter. We present a list of plausible logical validities and invalidities for the logic of (...) knowledge per se for arbitrary agents, and isolate three explanatory factors for them: the topic-sensitivity of content; the fragmentation of knowledge states; the defeasibility of knowledge acquisition. We then present a novel dynamic epistemic logic that yields precisely the desired validities and invalidities, for which we provide expressivity and completeness results. We contrast this with related systems and address possible objections. (shrink)

Our topic is the theory of topics. My goal is to clarify and evaluate three competing traditions: what I call the way-based approach, the atom-based approach, and the subject-predicate approach. I develop criteria for adequacy using robust linguistic intuitions that feature prominently in the literature. Then I evaluate the extent to which various existing theories satisfy these constraints. I conclude that recent theories due to Parry, Perry, Lewis, and Yablo do not meet the constraints in total. I then introduce the (...) issue-based theory—a novel and natural entry in the atom-based tradition that meets our constraints. In a coda, I categorize a recent theory from Fine as atom-based, and contrast it to the issue-based theory, concluding that they are evenly matched, relative to our main criteria of adequacy. I offer tentative reasons to nevertheless favour the issue-based theory. (shrink)

Article copyright 2002. We provide a battery of examples of delusions against which theoretical accounts can be tested. Then we identify neuropsychological anomalies that could produce the unusual experiences that may lead, in turn, to the delusions in our battery. However, we argue against Maher's view that delusions are false beliefs that arise as normal responses to anomalous experiences. We propose, instead, that a second factor is required to account for the transition from unusual experience to delusional belief. The second (...) factor in the etiology of delusions can be described superficially as a loss of the ability to reject a candidate for belief on the grounds of its implausibility and its inconsistency with everything else that the patient knows, but we point out some problems that confront any attempt to say more about the nature of this second factor.

Logics of joint strategic ability have recently received attention, with arguably the most influential being those in a family that includes Coalition Logic (CL) and Alternating-time Temporal Logic (ATL). Notably, both CL and ATL bypass the epistemic issues that underpin Schelling-type coordination problems, by apparently relying on the meta-level assumption of (perfectly reliable) communication between cooperating rational agents. Yet such epistemic issues arise naturally in settings relevant to ATL and CL: these logics are standardly interpreted on structures where agents move (...) simultaneously, opening the possibility that an agent cannot foresee the concurrent choices of other agents. In this paper we introduce a variant of CL we call Two-Player Strategic Coordination Logic (SCL2). The key novelty of this framework is an operator for capturing coalitional ability when the cooperating agents cannot share strategic information. We identify significant differences in the expressive power and validities of SCL2 and CL2, and present a sound and complete axiomatization for SCL2. We briefly address conceptual challenges when shifting attention to games with more than two players and stronger notions of rationality. (shrink)

We explore some possibilities for developing epistemic logic using truthmaker semantics. We identify three possible targets of analysis for the epistemic logician. We then list some candidate epistemic principles and review the arguments that render some controversial. We then present the classic Hintikkan approach to epistemic logic and note—as per the ‘problem of logical omniscience’—that it validates all of the aforementioned principles, controversial or otherwise. We then lay out a truthmaker framework in the style of Kit Fine and present six (...) different ways of extending this semantics with a conditional knowledge operator, drawing on notions of implication and content that are prominent in Fine’s work. We demonstrate that different logics are thereby generated, bearing on the aforementioned epistemic principles. Finally, we offer preliminary observations about the prospects for each logic.

This collection of texts (originally published in German under the title Holzwege) is Heidegger's first post-war book and contains some of the major expositions of his later philosophy. Of particular note are 'The Origin of the Work of Art', perhaps the most discussed of all of Heidegger's essays, and 'Nietzsche's Word 'God is Dead',' which sums up a decade of Nietzsche research. Although translations of the essays have appeared individually in a variety of places, this is the first English translation (...) to bring them all together as Heidegger intended. The text is taken from the last edition of the work, which contains the author's final corrections together with important marginal annotations that provide considerable insight into the development of his thought. This fresh and accurate new translation will be an invaluable resource for all students of Heidegger, whether they work in philosophy, literary theory, religious studies, or intellectual history.

This article explores the notion of gender overdetermination in relation to a community of criminalised women in Massachusetts. Re-examining classic writings on overdetermination by Louis Althusser, Sigmund Freud, Frantz Fanon and Jean-Paul Sartre, we query the notion of gender overdetermination and posit it as an effective lens for thinking about the persistence of gender as a social construct. The combination of the structural processes of overdetermination with the discursive and ideological power of overdetermination complicates and reduces possibilities and effectiveness of (...) sustained acts of resistance. The criminalised women of our study permanently inhabit a space in which aetiology, practice, discipline and interpretation are all hyper-gendered, meaning that acts of resistance are construed as more evidence of inescapable and essential gender identity.

Expressivists about epistemic modals deny that ‘Jane might be late’ canonically serves to express the speaker’s acceptance of a certain propositional content. Instead, they hold that it expresses a lack of acceptance. Prominent expressivists embrace pragmatic expressivism: the doxastic property expressed by a declarative is not helpfully identified with that sentence’s compositional semantic value. Against this, we defend semantic expressivism about epistemic modals: the semantic value of a declarative from this domain is the property of doxastic attitudes it canonically serves (...) to express. In support, we synthesize data from the critical literature on expressivism—largely reflecting interactions between modals and disjunctions—and present a semantic expressivism that readily predicts the data. This contrasts with salient competitors, including: pragmatic expressivism based on domain semantics or dynamic semantics; semantic expressivism à la Moss [2015]; and the bounded relational semantics of Mandelkern [2019].

This paper addresses a problem about epistemic warrant. The problem is posed by philosophical arguments for externalism about the contents of thoughts, and similarly by philosophical arguments for architecturalism about thinking, when these arguments are put together with a thesis of first person authority. In each case, first personal knowledge about our thoughts plus the kind of knowledge that is provided by a philosophical argument seem, together, to open an unacceptably ‘non-empirical’ route to knowledge of empirical facts. Furthermore, this unwelcome (...) prospect of transferring a ‘non-empirical’ warrant from premises about our own mental states and about philosophical theory to a conclusion about external environment or internal architecture seems to depend upon little more than the possibility of knowledge by inference. (The use of the scare-quoted term ‘non-empirical’ is explained a couple of paragraphs further on.). (shrink)

When do two sentences say the same thing, that is, express the same content? We defend two-component (2C) semantics: the view that propositional contents comprise (at least) two irreducibly distinct constituents, (1) truth-conditions, and (2) subject-matter. We contrast 2C with one-component (1C) semantics, focusing on the view that subject-matter is reducible to truth- conditions. We identify exponents of this view and argue in favor of 2C. An appendix proposes a general formal template for propositional 2C semantics.

Is it right to convict a person of a crime on the basis of purely statistical evidence? Many who have considered this question agree that it is not, posing a direct challenge to legal probabilism – the claim that the criminal standard of proof should be understood in terms of a high probability threshold. Some defenders of legal probabilism have, however, held their ground: Schoeman (1987) argues that there are no clear epistemic or moral problems with convictions based on purely (...) statistical evidence, and speculates that our aversion to such convictions may be nothing more than an irrational bias. More recently, Hedden and Colyvan (2019, section VI) describe our reluctance to convict on the basis of purely statistical evidence as an ‘intuition’, but suggest that there may be no ‘in principle’ problem with such convictions (see also Papineau, forthcoming, section 6). In this paper, I argue that there is, in some cases, an in principle problem with a conviction based upon statistical evidence alone – namely, it commits us to a precedent which, if consistently followed through, could lead to the deliberate conviction of an innocent person. I conclude with some reflections on the idea that the criminal justice system should strive to maximise the accuracy of its verdicts – and the related idea that we should each strive to maximise the accuracy of our beliefs.

This book traces the development of theories of the self and personal identity from the ancient Greeks to the present day. From Plato and Aristotle to Freud and Foucault, Raymond Martin and John Barresi explore the works of a wide range of thinkers and reveal the larger intellectual trends, controversies, and ideas that have revolutionized the way we think about ourselves. The authors open with ancient Greece, where the ideas of Plato, Aristotle, and the materialistic atomists laid the groundwork for (...) future theories. They then discuss the ideas of the church fathers and medieval and Renaissance philosophers, including St. Paul, Philo, Augustine, Aquinas, and Montaigne. In their coverage of the emergence of a new mechanistic conception of nature in the seventeenth century, Martin and Barresi note a shift away from religious and purely philosophical notions of self and personal identity to more scientific and social conceptions, a trend that has continued to the present day. They explore modern philosophy and psychology, including the origins of different traditions within each discipline, and explain both the theoretical relevance of feminism and gender and ethnic studies and also the ways that Derrida and other recent thinkers have challenged the very idea that a unified self or personal identity even exists. Martin and Barresi cover a number of issues broached by philosophers and psychologists, such as the existence of a fixed and unchanging self and whether the concept of the soul has a use outside of religious contexts. They address the question of whether notions of the soul and the self are still viable in today's world. Together, they reveal the fascinating ways in which great thinkers have grappled with these and other questions and the astounding impact their ideas have had on the development of self-understanding in the west.

According to a view widely held by epistemic contextualists, the truth conditions of a knowledge claim depend on features of the context such as the presuppositions, interests and purposes of the conversational participants. Against this view, I defend an intentionalist account, according to which the truth conditions of a knowledge attribution are determined by the speaker’s intention. I show that an intentionalist version of contextualism has several advantages over its more widely accepted rival account.

This chapter gives substance to the idea of a ‘communitarian value-driven epistemology’ by developing and combining ideas from Edward Craig's and Bernard Williams' ‘epistemic genealogy’ and Barry Barnes' and Steven Shapin's ‘sociology of knowledge’. In order to make transparent how this project might slot into more familiar, or more mainstream, projects, the paper maintains throughout a critical dialogue with Jon Kvanvig's position. The chapter is structured around an attempt to defend Craig's position against Kvanvig's criticisms: by treating the institution of (...) testimony as a collective good underwritten by the intrinsic and interrelated values of accuracy and sincerity; by rendering protoknowledge attributions as ascriptions of honour; and by allowing attributions of protoknowledge to be intertwined with attributions of freedom. The view that emerges is that the core of our knowledge practices comprises institutions of testimony, and that these practices are a collective good. (shrink)

Taking issue with those who see recent social transformations as an extension of modernity, the author contends that social theory must confront an epochal change from the modern era to a new era of globality, in which human beings can conceive of forces at work on a global scale, and in which they espouse values that take the globe as their reference point. The book begins by assessing the problems of writing about modernity, showing how narratives of an endlessly self-perpetuating (...) modern age were intrinsic to the "modern project," the attempt by Enlightenment philosophers to transform the everyday world in accord with science and logic under the auspices of the nation-state. Now we are beginning to realize that the nation-state and the modern project cannot renew themselves endlessly through expansion. Instead, the author contends, the age has culminated in its own dissolution, and globality has supplanted modernity as the basis for action and social organization. In theorizing the global age, he considers the worldwide environmental consequences of aggregate human activities, the reconception of human security in the age of nuclear weapons, technological advances in communication systems, the rise of a global economy, and the growing reflexivity of global consciousness, as people and groups begin to refer to the globe as the frame for their beliefs. The book concludes by examining the consequences of the Global Age thesis for politics, identifying a new popular construction of the state that the author terms "performative citizenship." In the modern age, the nation-state was the central power and citizens were beneficiaries of that power, with rights and duties. In the global age, citizens respond to the lack of central power by creating, or performing, the state themselves. The global managerial class uses the skills learned in the bureaucracy of the nation-state to bring pressure on national governments in the interests of global economic, environmental, or human-rights issues.

A landmark discussion between two great thinkers, vital to an understanding of twentieth-century philosophy and intellectual history.

The ratio of index- and ring-finger lengths is thought to be related to prenatal androgen exposure, and in many, though not all, populations, men have a lower average digit ratio than do women. In many studies an inverse relationship has been observed, among both men and women, between 2D:4D ratio and measures of athletic ability. It has been further suggested that, in hunter-gatherer populations, 2D:4D ratio might also be negatively correlated with hunting ability, itself assumed to be contingent on athleticism. (...) This hypothesis has been tested using endurance running performance among runners from a Western, educated, and industrialized population as a proximate measure of hunting ability. However, it has not previously been tested among actual hunter-gatherers using more ecologically valid measures of hunting ability and success. The current study addresses this question among Tanzanian Hadza hunter-gatherers. I employ a novel method of assessing hunting reputation that, unlike previous methods, allows granular distinctions to be made between hunters at all levels of perceived ability. I find no statistically significant relationship between digit ratio and either hunting reputation or two important hunting skills. I confirm that Hadza men have higher mean 2D:4D ratios than men in many Western populations. I discuss the notion that 2D:4D ratio may be the consequence of an allometric scaling relationship between relative and absolute finger lengths. Although it is difficult to draw clear conclusions from these results, the current study provides no support for the theorized relationship between 2D:4D ratio and hunting skill. (shrink)
