Michael Williams and Keith DeRose defend their different versions of contextualism on the grounds that contextualism gives a better account of the ordinary use of epistemic terms than invariantist competitors. One aim of this paper is to explain why their arguments do not succeed. A further aim is to show that the dispute between contextualists and invariantists portrayed by Williams and DeRose is a narrow interpretation of the dispute: there are important contextualist and invariantist positions which fall outside the scope (...) of their arguments and which a full defense of contextualism should consider.

Several recent contextualist theorists have proposed contextualizing the skeptic. Their claim is that oneshould view satisfactory answers to global doubts regarding such subjects as theexternal world, other minds, and induction as requirements for justification incertain philosophical contexts, but not in everyday and scientific contexts. Incontrast, the skeptic claims that a satisfactory answer to a global doubt in eachof these areas is a context-invariant requirement for justified belief. In this paper,I consider and reject the arguments Michael Williams develops in his bookUnnatural (...) Doubts that are intended to show that the skeptic's interpretationof the significance of global doubts is mistaken. In addition, I argue that Williams'general strategy in opposing the skeptic is extremely interesting and worth furtherinvestigation, even if his particular execution of it is unsuccessful. To this end, Iclarify the general strategy, distinguish it from a variety of others, and discuss itsprospects as an answer to the skeptic. (shrink)

In his book, Contemporary Theories of Knowledge, John Pollock argues that all externalist theories of justification should be rejected on the grounds that they do not do justice to the action-guiding character of epistemic norms. I reply that Pollocks argument is ineffective — because not all externalisms are intended to involve action-guiding norms, and because Pollock does not give a good reason for thinking that action-guiding norms must be internalist norms. Second, I consider rehabilitating Pollocks argument by restricting his conclusion (...) to theories that do involve action-guiding norms and providing a better reason to think that action-guiding norms must be internalist norms. But I claim that if Pollocks argument is made strong enough to rule out all externalisms, it rules out too much, namely, any plausible conception of epistemic norms. (shrink)

In his influential paper ‘Two Types of Foundationalism,’ William Alston distinguishes two important conceptions of foundationalism: ‘simple foundationalism’ and ‘iterative foundationalism’. SF is the view that there are immediately justified beliefs of some kind or other. IF is the stronger view that certain epistemic propositions are immediately justified. Alston favors a reliability account of immediate justification of the kind defended by externalists such as Armstrong, Dretske, and Goldman. Alston rejects IF by appeal to what he calls the ‘second level argument.’ (...) He claims, further, that since IF is essential to the Cartesian project of reconstructing knowledge, the Cartesian project must be abandoned. (shrink)

Michael Williams e Keith DeRose defendem suas diferentes versões de contextualismo com base em que o contextualismo fornece uma explicação melhor do uso ordinário de termos epistêmicos que competidores invariantistas. Um objetivo deste trabalho é explicar por que seus argumentos não têm sucesso.

BackgroundKinarm Standard Tests is a suite of upper limb tasks to assess sensory, motor, and cognitive functions, which produces granular performance data that reflect spatial and temporal aspects of behavior. We have previously used principal component analysis to reduce the dimensionality of multivariate data using the Kinarm End-Point Lab. Here, we performed PCA using data from the Kinarm Exoskeleton Lab, and determined agreement of PCA results across EP and EXO platforms in healthy participants. We additionally examined whether further dimensionality reduction (...) was possible by using PCA across behavioral tasks.MethodsHealthy participants were assessed using the Kinarm EXO and EP. Four behavioral tasks were performed that quantified arm sensory and motor function, including position sense [Arm Position Matching ] and three motor tasks [Visually Guided Reaching, Object Hit, and Object Hit and Avoid ]. The number of components to include per task was determined from scree plots and parallel analysis, and rotation type was decided on a per-task basis. To assess agreement, we compared principal components across platforms using distance correlation. We additionally considered inter-task interactions in EXO data by performing PCA across all six behavioral assessments.ResultsBy applying PCA on a per task basis to data collected using the EXO, the number of behavioral parameters were substantially reduced by 58–75% while accounting for 76–87% of the variance. These results compared well to the EP analysis, and we found good-to-excellent agreement values between PCs from the EXO and those from the EP. Finally, we were able to reduce the dimensionality of the EXO data across tasks down to 16 components out of a total of 76 behavioral parameters, which represents a reduction of 79% while accounting for 73% of the total variance.ConclusionPCA of Kinarm robotic assessment appears to capture similar relationships between kinematic features in healthy individuals and is agnostic to the robotic platform used for collection. Further work is needed to investigate the use of PCA-based data reduction for the characterization of neurological deficits in clinical populations. (shrink)

Undergraduate students with no prior classroom instruction in mathematical logic will benefit from this evenhanded multipart text by one of the centuries greatest authorities on the subject. Part I offers an elementary but thorough overview of mathematical logic of first order. The treatment does not stop with a single method of formulating logic; students receive instruction in a variety of techniques, first learning model theory (truth tables), then Hilbert-type proof theory, and proof theory handled through derived rules. Part II supplements (...) the material covered in Part I and introduces some of the newer ideas and the more profound results of logical research in the twentieth century. Subsequent chapters introduce the study of formal number theory, with surveys of the famous incompleteness and undecidability results of Godel, Church, Turing, and others. The emphasis in the final chapter reverts to logic, with examinations of Godel's completeness theorem, Gentzen's theorem, Skolem's paradox and nonstandard models of arithmetic, and other theorems.

This book examines the hypothesis of "direct compositionality", which requires that semantic interpretation proceed in tandem with syntactic combination. Although associated with the dominant view in formal semantics of the 1970s and 1980s, the feasibility of direct compositionality remained unsettled, and more recently the discussion as to whether or not this view can be maintained has receded. The syntax-semantics interaction is now often seen as a process in which the syntax builds representations which, at the abstract level of logical form, (...) are sent for interpretation to the semantics component of the language faculty. In the first extended discussion of the hypothesis of direct compositionality for twenty years, this book considers whether its abandonment might have been premature and whether in fact direct compositionality is not after all a simpler and more effective conception of the grammar than the conventional account of the syntax-semantics interface in generative grammar. It contains contributions from both sides of the debate, locates the debate in the setting of a variety of formal theories, and draws on examples from a range of languages and a range of empirical phenomena.

Drawing from Benjamin's and Scholem's ideas on messianism, language, and divine justice, this book traces the intellectual exchange through the early decades of the twentieth century—from Berlin, Bern, and Munich in the throws of war and revolution to Scholem's departure for Palestine in 1923. It begins with a close reading of Benjamin's early writings and a study of Scholem's theological politics, followed by an examination of Benjamin's proposals on language and the influence these ideas had on Scholem's scholarship on Jewish (...) mysticism. From there the book turns to their ideas on divine justice—from Benjamin's critique of original sin and violence to Scholem's application of the categories to the prophets and Bolshevism. Metaphysics of the Profane is the first book to make this early period available to a wider audience, revealing the intricate structure of this early intellectual partnership on politics and theology.

The question of whether conscious experience is restricted by cognitive access and exhausted by report, or whether it overflows it—comprising more information than can be reported—is hotly debated. Recently, we provided evidence in favor of Overflow, showing that observers discriminated the color‐diversity (CD) of letters in an array, while their working‐memory and attention were dedicated to encoding and reporting a set of cued letters. An alternative interpretation is that CD‐discriminations do not entail conscious experience of the underlying colors. Here we (...) argue, based on conceptual considerations and consistency with neuroscience and phenomenology, in favor of the Overflow interpretation. (shrink)

According to Slote's ``agent-based'' virtue ethics, the rightness orwrongness of an act is determined by the motive it expresses. Thistheory has a problem with cases where an agent can do her duty onlyby expressing some vicious motive and thereby acting wrongly. In sucha situation, an agent can only act wrongly; hence, the theory seemsincompatible with the maxim that `ought' implies `can'. I argue thatSlote's attempt to circumvent this problem by appealing to compatibilism is inadequate. In a wide range of psychologically (...) realistic cases, an agent's effective choice will be between failingto do her duty and doing it from inferior motives. Then anythingshe can do will be wrong, according to the agent-based theory,contrary to the maxim Slote wishes to preserve. (shrink)

Stephen Toulmin argues that the potential for reason to improve our lives has been hampered by a serious imbalance in our pursuit of knowledge. The centuries-old dominance of rationality has diminished the value of reasonableness. Toulmin issues a powerful call to redress the balance between rationality and reasonableness.

Philosophers often call emotions appropriate or inappropriate. What is meant by such talk? In one sense, explicated in this paper, to call an emotion appropriate is to say that the emotion is fitting: it accurately presents its object as having certain evaluative features. For instance, envy might be thought appropriate when one's rival has something good which one lacks. But someone might grant that a circumstance has these features, yet deny that envy is appropriate, on the grounds that it is (...) wrong to be envious. These two senses of `appropriate' have much less in common than philosophers have supposed. Indeed, the distinction between propriety and correctness is crucial to understanding the distinctive role of the emotions in ethics. We argue here that an emotion can be fitting despite being wrong to feel, and that various philosophical arguments are guilty of a systematic error which we term the moralistic fallacy. (shrink)

"Biophilia" is the term coined by Edward O. Wilson to describe what he believes is humanity's innate affinity for the natural world. In his landmark book Biophilia, he examined how our tendency to focus on life and lifelike processes might be a biologically based need, integral to our development as individuals and as a species. That idea has caught the imagination of diverse thinkers. The Biophilia Hypothesis brings together the views of some of the most creative scientists of our time, (...) each attempting to amplify and refine the concept of biophilia. The variety of perspectives -- psychological, biological, cultural, symbolic, and aesthetic -- frame the theoretical issues by presenting empirical evidence that supports or refutes the hypothesis. Numerous examples illustrate the idea that biophilia and its converse, biophobia, have a genetic component: fear, and even full-blown phobias of snakes and spiders are quick to develop with very little negative reinforcement, while more threatening modern artifacts -- knives, guns, automobiles -- rarely elicit such a response people find trees that are climbable and have a broad, umbrella-like canopy more attractive than trees without these characteristics people would rather look at water, green vegetation, or flowers than built structures of glass and concrete The biophilia hypothesis, if substantiated, provides a powerful argument for the conservation of biological diversity. More important, it implies serious consequences for our well-being as society becomes further estranged from the natural world. Relentless environmental destruction could have a significant impact on our quality of life, not just materially but psychologically and even spiritually. (shrink)

What does it mean to think of philosophy in the condition of modernism, in which its relation to its past and future has become a relevant problem? This book argues that the writings of Wittgenstein, Heidegger, and Kierkegaard are best understood as responsive (each in their own way) to such questions. Through detailed analysis of these authors' most influential texts, Stephen Mulhall reorients our sense of the philosophical work each text aims to accomplish, engendering a critical dialogue between them (...) from which the elements of a new conception of philosophy might emerge.

Transnational corporations have become actors with significant political power and authority which should entail responsibility and liability, specifically direct liability for complicity in human rights violations. Holding TNCs liable for human rights violations is complicated by the discontinuity between the fragmented legal/political structure of the TNC and its integrated strategic reality and the international state system which privileges sovereignty and non-intervention over the protection of individual rights. However, the post-Westphalian transition—the emergence of multiple authorities, increasing ambiguity of borders and jurisdiction (...) and blurring of the line between the public and private spheres—should facilitate imposing direct responsibility on transnational firms. Mechanisms for imposing direct responsibility on TNCs are considered including voluntary agreements and international law. However, I conclude that a hybrid public-private regime which relies on non-hierarchical compliance mechanisms is likely to be both more effective and consistent with the structure of the emerging transnational order.

Organizational aesthetics, both as a body of theory and a method of inquiry, is a rapidly expanding area of the organizational sciences. The Aesthetics of Organization accessibly draws key contributions delineating the emerging parameters of the field. It explains the significance of concepts devised by postmodern thinkers, through which emerge meaning and order in organizations. Methodological problems associated with investigations of the aesthetic are also highlighted so the reader can identify and understand the importance of recent ideas on vision, perspective (...) and periphery for learning in organizations. Through the contributions of leading international theorists, organizational aesthetics is defined in greater historical and theoretical depth, with a broad conceptual and practical range which academics will find invaluable.

Hume's Enlightenment Tract is the first full study for forty years of David Hume's Enquiry concerning Human Understanding. The Enquiry has, contrary to its author's expressed wishes, long lived in the shadow of its predecessor, A Treatise of Human Nature. Stephen Buckle presents the Enquiry in a fresh light, and aims to raise it to its rightful position in Hume's work and in the history of philosophy.

A central theme throughout the impressive series of philosophical books and articles Stephen Toulmin has published since 1948 is the way in which assertions and opinions concerning all sorts of topics, brought up in everyday life or in academic research, can be rationally justified. Is there one universal system of norms, by which all sorts of arguments in all sorts of fields must be judged, or must each sort of argument be judged according to its own norms? In The (...) Uses of Argument Toulmin sets out his views on these questions for the first time. In spite of initial criticisms from logicians and fellow philosophers, The Uses of Argument has been an enduring source of inspiration and discussion to students of argumentation from all kinds of disciplinary background for more than forty years.
