Tacit knowledge is the form of implicit knowledge that we rely on for learning. It is invoked in a wide range of intellectual inquiries, from traditional academic subjects to more pragmatically orientated investigations into the nature and transmission of skills and expertise. Notwithstanding its apparent pervasiveness, the notion of tacit knowledge is a complex and puzzling one. What is its status as knowledge? What is its relation to explicit knowledge? What does it mean to say that knowledge is tacit? Can (...) it be measured? Recent years have seen a growing interest from philosophers in understanding the nature of tacit knowledge. Philosophers of science have discussed its role in scientific problem-solving; philosophers of language have been concerned with the speaker's relation to grammatical theories; and phenomenologists have attempted to describe the relation of explicit theoretical knowledge to a background understanding of matters that are taken for granted. This book seeks to bring a unity to these diverse philosophical discussions by clarifying their conceptual underpinnings. In addition the book advances a specific account of tacit knowledge that elucidates the importance of the concept for understanding the character of human cognition, and demonstrates the relevance of the recommended account to those concerned with the communication of expertise. The book will be of interest to philosophers of language, epistemologists, cognitive psychologists and students of theoretical linguistics. (shrink)

Since Michael Polanyi coined the term “tacit knowledge” in 1958, a huge amount of literature has been produced on this topic. Gascoigne and Thornton’s monograph represents one of the most recent attempts to clarify the concept of tacit knowledge.For other recent publications on tacit knowledge see Collins , Yu and Turner . In their engagement with various thinkers, most notably Polanyi, Ryle, Heidegger, Wittgenstein, John Searle, Hubert Dreyfus, and John McDowell, etc., the authors make impressive efforts to situate the (...) discussion of tacit knowledge in the context of mainstream philosophy. They shed new light on the concept of tacit knowledge by embedding it in contemporary debates, such as those on knowing how, rule-following, conceptualism, language maste .. (shrink)

Aristotle’s discussions of natural slavery, ‘barbarian kingship’, and the natural characteristics of barbarians or non-Greeks are usually read as calling into question the intellectual, ethical, and political accomplishments of non-Greeks. Such accounts of non-Greek inferiority or inability to self-govern also appear to presuppose a climatic or environmental account that on the whole would imply severe limitations on the possibility of political flourishing for peoples living outside the Greek Mediterranean basin. In light of such accounts, it is somewhat astounding to find (...) Aristotle praising the social and political institutions of Carthage within his discussion of the best constitution in the second book of the Politics. In the 4th century BCE, Carthage (modern day Tunis) was a Phoenician commercial empire that culturally and linguistically was Semitic and clearly non-Greek. That Aristotle contrasts Carthage, a non-Greek polis, favorably with both Sparta and Crete undermines both the claim that Aristotle embraced a categorical opposition between Greeks and non-Greeks and the claim that he was dismissive of the achievements of non-Greeks.

In his account of the Persian Wars, the 5th century historian Herodotus reports an exchange between the Persian monarch Xerxes and a deposed Spartan king, Demaratus, who became what Lattimore later classified as a “tragic warner” to Xerxes. On the eve of the battle of Thermopylae, Xerxes asks how a small number of free Spartiates can stand up against the massive ranks of soldiers that Xerxes has assembled. Herodotus has Demaratus reply: So is it with the Lacedaemonians; fighting singly they (...) are as brave as any man living, and together they are the best warriors on earth. Free they are, yet not wholly free; for law is their master (ἐλεύθεροι γὰρ ἐόντες οὐ πάντα ἐλεύθεροι εἰσί· ἔπεστι γάρ σφι δεσπότης νόμος), whom they fear much more than your men fear you. This is my proof—what their law bids them, that they do; and its bidding is ever the same, that they must never flee from the battle before whatsoever odds, but abide at their post and there conquer or die. (Hdt. 7.104) As the outcome of Thermopylae makes clear, Demaratus is hardly guilty of boasting. But Greek political theorists were not only fascinated by the Spartans who fought at the battle of Thermopylae in 480; they also wondered how slightly more than a century later Sparta was ignobly defeated by Thebes at the battle of Leuctra in 371, after which Spartan hegemony collapsed. How did Sparta field citizen-soldiers in the 5th century who were without parallel in their bravery and military prowess? And why did Sparta, predominantly under the same political organization, collapse just over a century later? Such are the main questions that Xenophon, Plato, Aristotle, and Plutarch—what Cartledge (1999, 313–14) has characterized as “political-theoretical” laconophiles—seek to answer in their writings about Sparta.

John McDowell's contribution to philosophy has ranged across Greek philosophy, philosophy of language, philosophy of mind, metaphysics and ethics. His writings have drawn on the works of, amongst others, Aristotle, Kant, Hegel, Frege, Russell, Wittgenstein, Sellars, and Davidson. His contributions have made him one of the most widely read, discussed and challenging philosophers writing today. This book provides a careful account of the main claims that McDowell advances in a number of different areas of philosophy. The interconnections between the different (...) arguments are highlighted and Tim Thornton shows how these individual projects are unified in a post-Kantian framework that articulates the preconditions of thought and language. Thornton sets out the differing strands of McDowell's work prior to, and leading up to, their combination in the broader philosophical vision revealed in "Mind and World" and provides an interpretative and critical framework that will help shape ongoing debates surrounding McDowell's work. An underlying theme of the book is whether McDowell's therapeutic approach to philosophy, which owes much to the later Wittgenstein, is consistent with the substance of McDowell's discussion of nature that uses the vocabulary of other philosophers including, centrally, Kant.

Essential Philosophy of Psychiatry is a concise introduction to the growing field of philosophy of psychiatry. Divided into three main aspects of psychiatric clinical judgement, values, meanings and facts, it examines the key debates about mental health care, and the philosophical ideas and tools needed to assess those debates, in six chapters. In addition to outlining the state of play, Essential Philosophy of Psychiatry presents a coherent and unified approach across the different debates, characterized by a rejection of reductionism and (...) an emphasis on the ineliminability of uncodified skilled judgement. The first part, Values, outlines the debate about whether diagnosis of mental illness is essentially value-laden and argues that the prospects for reducing illness or disease to plainly factual matters are poor. It also explains the important role of skilled contextual judgement, rather than a principles-based deduction, in ethical judgement. The second part, Meanings, examines the central role of understanding and a shared first person perspective, both against attempts to reduce meaning to basic information-processing mechanisms and to explain away the difficulties of understanding psychopathology in recent models of delusion. The third part, Facts, shows the importance of uncodified clinical judgements, both in assessing the validity of psychiatric taxonomy and in the application of Evidence Based Medicine. Despite advances in the codifaction of practice and operationalism of diagnosis, an element of judgement remains in the assessment both of what, at one level, is good evidence for diagnosis and treatment and what, at a higher level, is good evidence for the validity of classification overall.

This paper elaborates and defends an expressivist account of the claims of mind-independence embedded in ordinary moral thought. In response to objections from Zangwill and Jenkins it is argued that the expressivist 'internal reading' of such claims is compatible with their conceptual status and that the only 'external reading' available doesn't commit expressivisists to any sort of subjectivism. In the process a 'commitment-theoretic' account of the semantics of conditionals and negations is defended.

John McDowell is one of the most widely read philosophers in recent years. His engagement with a philosophy of language, mind and ethics and with philosophers ranging from Aristotle and Wittgenstein to Hegel and Gadamer make him one of the most original and outstanding philosophical thinkers of the post-war period. In this clear and engaging book Tim Thornton introduces and examines the full range of McDowell's thought. After a helpful introduction setting out McDowell's general view of philosophy Thornton (...) introduces and explains the following topics: • Wittgenstein on philosophy, normativity and understanding • value judgements • theories of meaning and sense • singular thought and Cartesianism • experience, knowledge and openness to the world • Mind and World and idealism • action and the debate with Hubert Dreyfus on conceptual content and skilled coping. This second edition has been significantly revised and expanded to include new sections on: McDowell's work on disjunctivism and criticisms of it; a new chapter on McDowell's modification of his account of perceptual experience and conceptual content and criticisms by Charles Travis; and a new chapter on action and McDowell's engagement with Hubert Dreyfus and the debate concerning skilled coping and mindedness. The addition of a glossary makes John McDowell, second edition essential reading for those studying McDowell, philosophy of language, philosophy of mind, ethics and epistemology, as well as for students of the recent history of analytical philosophy generally. Tim Thornton is Professor of Philosophy and Mental Health at University of Central Lancashire, UK. He is author of Essential Philosophy of Psychiatry (2007), Wittgenstein on Language and Thought (1998), co-author of the Oxford Textbook of Philosophy and Psychiatry (2006), and Tacit Knowledge (2013) and co-editor of the Oxford Handbook of Philosophy and Psychiatry (2013).

Is it possible to invoke the use of moral responsibility as part of the selection criteria in the allocation of livers for transplant? Criticism has been applied to the difficulties inherent in including such a criterion and also the effect that employing such a judgement might have upon the relationship between the physician and patient. However, these criticisms rely on speculation and conjecture and do not relate to all the arguments put forward in favour of applying moral responsibility. None of (...) the present arguments against using moral responsibility in the allocation of livers for transplant are good enough to warrant its dismissal. (shrink)

Eco-Rational Education proposes an educational response to climate change, environmental degradation, and desctructive human relations to ecology through the delivery of critical land-responsive environmental education. -/- The book argues that education is a powerful vehicle for both social change and cultural reproduction. It proposes that the prioritisation and integration of environmental education across the curriculum is essential to the development of ecologically rational citizens capable of responding to the environmental crisis and an increasingly changing world. Using philosophical analysis, particularly environmental (...) philosophy, pragmatism, and ecofeminism, the book develops an understanding of contemporary issues in education, especially inquiry-based learning as pedagogy, diversifying knowledge, environmental and epistemic justice, climate change education, and citizenship education. -/- Eco-Rational Education will be of interest to researchers and post-graduate students of social and political philosophy, educational philosophy, as well as environmental philosophy, ethics, and teacher education.

Some people argue that the distribution of medical resources should be sensitive to agents’ responsibility for their ill-health. In contrast, others point to the social determinants of health to argue that the collective agents that control the conditions in which agents act should bear responsibility. To a large degree, this is a debate in which those who hold individuals responsible currently have the upper hand: warranted appeals to individual responsibility effectively block allocation of any significant degree of responsibility to collective (...) agents. We suggest that a different understanding of individual responsibility might lead to a fairer allocation of blame. Scaffolded agency is individual agency exercised in a context in which opportunities and affordances are structured by others. Appeals to scaffolded agency at once recognize the role of the individual and of the collective agents who have put the scaffolds in place. (shrink)

I defend hedonism about moral value by first presenting an argument for moral skepticism, and then showing that phenomenal introspection gives us a unique way to defeat the skeptical argument and establish pleasure's goodness.

McKenna’s critique (rather than criticisms) of idealized approaches to epistemology is an important contribution to the literature. In this brief discussion, I set out his main concerns about more idealized approaches, within and beyond social epistemology, before turning to some issues I think he neglects. I suggest that it’s important to pay attention to the prestige hierarchy in philosophy, and to how that hierarchy can serve ideological purposes. The greater prestige of more abstract approaches plays a role in determining what (...) issues and what voices we attend to. (shrink)

An account of how a rational agent should revise beliefs in the light of new evidence.

This book highlights the philosophical and creative basis of knowledge co-production by all citizens regardless of socio-economic background in contrast with neoliberal ideology. Exploring beginning, transitional and theorised practices, the book is a memoir of the author's extensive personal and educational experience. Each topic is discussed in relation to a number of pragmatist themes that run throughout to illustrate how the process of dialectical emergence underpins and substantiates meaningful human living. Building on the work of American Pragmatism, this is a (...) systematic and detailed reintroduction of pragmatism to educators worldwide for progressive educational change. (shrink)

Aristotle’s claim that poetry is ‘a more philosophic and better thing’ than history (Poet 9.1451b5-6) and his description of the ‘poetic universal’ have been the source of much scholarly discussion. Although many scholars have mined Poetics 9 as a source for Aristotle’s views towards history, in my contribution I caution against doing so. Critics of Aristotle’s remarks have often failed to appreciate the expository principle which governs Poetics 6-12, which begins with a definition of tragedy and then elucidates the terms (...) of that definition by means of a series of juxtapositions. The juxtaposition between poetry and history is one such instance which seeks to elucidate what sort of plot exemplifies a causal unity such that the events of a play unfold with likelihood or necessity. Within that context, Aristotle compares history and poetry in order to elucidate the object of poetic mimesis rather than criticize history as a discipline. Viewing Aristotle as antagonistic towards history fails to appreciate the expository structure of the Poetics and obscures the resource which history provides to the poet, a point which I explore by considering what Aristotle would have thought of an ‘historical’ tragedy like Aeschylus’ Persians.

Despite its authors’ intentions, the four principles approach to medical ethics can become crudely algorithmic in practice. The first section sets out the bare bones of the four principles approach drawing out those aspects of Beauchamp and Childress’s Principles of biomedical ethics that encourage this misreading. The second section argues that if the emphasis on the guidance of moral judgement is augmented by a particularist account of what disciplines it, then the danger can be reduced. In the third section, I (...) consider how much the resultant picture diverges from Beauchamp and Childress’s actual position. (shrink)

Causal theories of action, perception and knowledge are each beset by problems of so-called ‘deviant’ causal chains. For each such theory, counterexamples are formed using odd or co-incidental causal chains to establish that the theory is committed to unpalatable claims about some intentional action, about a case of veridical perception or about the acquisition of genuine knowledge. In this paper I will argue that three well-known examples of a deviant causal chain have something in common: they each violate Yablos proportionality (...) constraint on causation. I will argue that this constraint provides the key to saving causal theories from deviant chains. (shrink)

In the autumn of 430 BCE, the city of Athens was devastated by a plague, one chronicled by both the Athenian historian Thucydides and the Roman poet Lucretius. Albert Camus’ notebooks and novel The Plague (La peste) clearly show his interest in the plague of Athens and several scholars have detected comparisons between its narrator, Dr. Rieux, and the historian Thucydides. But a careful examination of what Rieux actually says about the plague of Athens complicates matters and suggests that Camus (...) in some sense rejects accounts of the plague of Athens as a model for his novel. Such a rejection seems confirmed by the novel’s identification of Joseph Grand as its hero, an example of decidedly non-Periclean virtue. I argue that although one can find comparisons within the Plague between Athens and Oran, more pronounced are their contrasts. (shrink)

Unshakable Pursuit, a 30-day devotional, calls you to recognize God's eternal momentum at work in those fully engaged in His story.

Time passes; sometimes swiftly, sometimes interminably, but always it passes. We see the world change as events emerge from the shroud of the future, clandestinely slinking into the past almost immediately as though they are reluctant to meet our gaze: children are born, old friends and relatives die, governments once full of youthful enthusiasm wane. If the Earth were sentient, it might feel itself being torn apart as tectonic plates diverge, and chuckle as it outlived species upon species of transient (...) parasites. How could anyone possibly deny that time passes? (shrink)

How may we characterize the intrinsic structure of physical quantities such as mass, length, or electric charge? This article shows that group-theoretic methods—specifically, the notion of a free and transitive group action—provide an elegant way of characterizing the structure of scalar quantities, and uses this to give an intrinsic treatment of vector quantities. It also gives a general account of how different scalar or vector quantities may be algebraically combined with one another. Finally, it uses this apparatus to give a (...) simple intrinsic treatment of Newtonian gravitation. (shrink)

Psychiatry’s inchoate wish for a paradigm shift and the biopsychosocial model of mental illness’ critically examines the much discussed goal of a paradigm shift in psychiatric taxonomy. The chapter first highlights some illustrative calls for such a change and then sets these against the Kuhnian account of science from which the idea is taken, highlighting the connection to incommensurability. Relative to a distinction drawn from Winch, between putative sciences where the self-understanding of subjects plays no role and those where it (...) is fundamental, psychiatry falls into the latter kind. This suggests that the wish for a paradigm shift in psychiatry is either incoherent or a wish for a radical but unpredictable overhaul of a significant aspect of our self-understanding as subjects and agents. The biopsychosocial model of mental illness is thus a helpful reminder of the cost of a paradigm shift in psychiatry. (shrink)

Informed consent is a central topic in contemporary biomedical ethics. Yet attempts to set defensible and feasible standards for consenting have led to persistent difficulties. In Rethinking Informed Consent in Bioethics Neil Manson and Onora O'Neill set debates about informed consent in medicine and research in a fresh light. They show why informed consent cannot be fully specific or fully explicit, and why more specific consent is not always ethically better. They argue that consent needs distinctive communicative transactions, by (...) which other obligations, prohibitions, and rights can be waived or set aside in controlled and specific ways. Their book offers a coherent, wide-ranging and practical account of the role of consent in biomedicine which will be valuable to readers working in a range of areas in bioethics, medicine and law.

We explain and explore class-theoretic potentialism—the view that one can always individuate more classes over a set-theoretic universe. We examine some motivations for class-theoretic potentialism, before proving some results concerning the relevant potentialist systems (in particular exhibiting failures of the $\mathsf {.2}$ and $\mathsf {.3}$ axioms). We then discuss the significance of these results for the different kinds of class-theoretic potentialists.

For more than 60 years, Chomsky has been an intellectual Colossus bestriding the worlds of language, philosophy, and the cognitive sciences, and focusing attention on the whole field and emphasizing the crucial importance of domains overlooked by the mainstream. One such area is the study of first‐language acquisition. This chapter considers “atypical acquisition” to cover two conceptually related situations. First, it covers a variety of cases where there is an obvious “poverty of the stimulus” in that children either receive or (...) perceive no linguistic input at the essential early stages referred to as critical periods. Second, it covers where there is rather the opposite situation. The chapter presents atypicality in language acquisition that stems from the learner's atypical neurological profile rather than environmental or input properties. It focuses on Developmental Language Disorder, Autism Spectrum Disorder, and the case of the polyglot‐savant Christopher to exemplify atypical acquisition. (shrink)

This book was written with my University of Mississippi "Philosophy of Religion" students in mind. Many of them have no prior experience with philosophy. That is why Chapter One begins with a crash course in philosophy, with an emphasis on the basic concepts in logic, metaphysics, and epistemology. While not all students may need to cover that material, quite a few will. And for the rest, a refresher never hurts. I am sure this applies to many "Philosophy of Religion" courses (...) taught elsewhere. With that in mind, instructors are advised to begin with Chapter One. The subsequent chapters have been arranged in sequence, with each chapter building on the prior ones. However, the chapters are not that tightly bound, so instructors could cover the chapters out of sequence without much disruption. Key terms are underlined. Sometimes the key terms also occur with an associated hyperlink. Other terms have a hyperlink without a corresponding key term. In the print the hyperlink is included as a footnote, in the ebooks the term is hyperlinked [Production - check the ebooks will have hyperlinbks - amend wording here if not]. In general, the hyperlinks follow a pattern. First, key terms are often linked to entries in online academic encyclopedias - either The Stanford Encyclopedia of Philosophy, The Internet Encyclopedia of Philosophy, or The Encyclopedia Britannica. [Students are recommended also to consult The Encyclopedia of Philosophy (1967), edited by Paul Edwards; it is still an excellent resource and has entries corresponding to many key terms. Almost every university library has a copy.] Second, named individuals are sometimes linked to an encyclopedia entry. In both sorts of cases, the URL is provided in an endnote at the end of each chapter. No other description of the contents of the web page will be given. In most other cases, a short description of the contents of the web page is provided in the endnote. Each chapter includes an annotated bibliography for more advanced material.

Informally rigorous mathematical reasoning is relevant. So too should be the premises to the conclusions of formal proofs that regiment it. The rule Ex Falso Quodlibet induces spectacular irrelevance. We therefore drop it.

We effect a revised match-up between deducibility in Classical Core Logic and a new notion of relevant logical consequence. It matches better the (...) deducibility relation of Classical Core Logic than does the Tarskian notion of consequence. It is implosive, not explosive. (shrink)

Offers a historical study of the world that contends that history is continually created and recreated by conscious, collective human action. Faulkner argues that the struggles of the common people--slaves, serfs, handloom weavers, mine workers, women fighting oppression, black people fighting racism, colonized people fighting imperialism--these struggles, occasionally fusing into mass revolutionary upsurges, drive the historical process. He states that this is an approach to history that emphasizes agency, contingency, and the existence of alternatives; an approach that rejects the view (...) that war and empire are inevitable, that there is no alternative to the market, and that greed, bullying, and violence are universal. In other words, Faulkner contends that the course of history is not predetermined, its outcome is not inevitable; it can go in different directions according to what human beings do. (shrink)

Making Sense of the World: Living, Learning and Teaching with Radical Philosophy of Education proposes that human knowledge arises from an integrated physical and metaphysical experience involving the continuing social acts of personal and community cultures and languages.

Given the dominance of neoliberal politics and economics in many (...) countries, it is unusual to find the work of educators and practitioners being framed generally by an explicit philosophy of knowledge.

One of the hardest parts of being a leader is handling disagreements about values. The skills required to do this are increasingly important in polarized societies where there is pressure for businesses and organizations to have a sense of purpose and "do the right thing." Our book helps readers address these challenges. To do this, we don''t give a simplistic cookie-cutter recipe for what is right and wrong. Rather, we guide readers on a journey to rigorously explore their values and (...) better understand the values of others. We discuss the human psychology that drives conflicts over values as well as the philosophical frameworks that have guided people for millennia. We provide strategies, based in research from psychology and the behavioral sciences, whichthat readers can use to implement their values in their lives and their organizations. Topics covered include moral intuitions, self-serving biases, situational pressures, social norms, the role of business in society, consequentialism/utilitarianism, motives, perspective-taking, justice, fairness, and liberty.

I defend ethical hedonism, the view that pleasure is the sole good thing, by arguing that it offers the only answer to an argument for moral skepticism. The skeptical problem arises from widespread fundamental moral disagreement, which entails the presence of enough moral error to undermine the reliability of most processes generating moral belief. We know that pleasure is good through the reliable process of phenomenal introspection, which reveals what our experiences are like. If knowing of pleasure’s goodness through phenomenal (...) introspection is the only reliable way to form our initial moral beliefs, we should accept ethical hedonism. (shrink)

Neil Levy presents a new theory of freedom and responsibility. He defends a particular account of consciousness--the global workspace view--and argues that consciousness plays an especially important role in action.

Epistemic akrasia can be rational. I consider a lonely pragmatist who believes that her imaginary friend doesn’t exist, and also believes on pragmatic grounds that she should believe in him. She rationally believes that her imaginary friend doesn’t exist, rationally follows various sources of evidence to the view that she should believe in him to end her loneliness, and rationally holds these attitudes simultaneously. Evidentialism suggests that her ambivalent epistemic state is rational, as considerations grounded in the value of truth (...) justify her beliefs. (shrink)
