Bringing about desirable collisions (making interceptions) and avoiding unwanted collisions are critically important sensorimotor skills, which appear to require us to estimate the time remaining before collision occurs (time-to-collision). Until recently the theoretical approach to understanding time-to-collision estimation has been dominated by the tau-hypothesis, which has its origins in J.J. Gibson’s ecological approach to perception. The hypothesis proposes that a quantity (tau), present in the visual stimulus, provides the necessary time-to-collision information. Empirical results and formal analyses have now accumulated to (...) demonstrate conclusively that the tau-hypothesis is false. This article describes an alternative approach that is based on recent data showing that the information used in judging time-to-collision is task- and situation-dependent, is of many different origins (of which tau is just one) and is influenced by the information-processing constraints of the nervous system.

The λ model suggests that detailed kinematics arise from changes in control variables and need not be explicitly planned. However, we have shown that when moving a grasped object, grip force is precisely modulated in phase with acceleration-dependent inertial load. This suggests that the motor system can predict detailed kinematics. This prediction may be based on a forward model of the dynamics of the loaded limb.

How (Not) to Be Secular is what Jamie Smith calls "your hitchhiker's guide to the present" -- it is both a reading guide to Charles Taylor's monumental work A Secular Age and philosophical guidance on how we might learn to live in our times. Taylor's landmark book A Secular Age (2007) provides a monumental, incisive analysis of what it means to live in the post-Christian present -- a pluralist world of competing beliefs and growing unbelief. Jamie Smith's book is a (...) compact field guide to Taylor's insightful study of the secular, making that very significant but daunting work accessible to a wide array of readers. Even more, though, Smith's How (Not) to Be Secular is a practical philosophical guidebook, a kind of how-to manual on how to live in our secular age. It ultimately offers us an adventure in self-understanding and maps out a way to get our bearings in today's secular culture, no matter who "we" are -- whether believers or skeptics, devout or doubting, self-assured or puzzled and confused. This is a book for any thinking person to chew on. (shrink)

Noted psychologist and philosopher develops his own brand of pragmatism, based on theories of C. S. Peirce. Emphasis on "radical empiricism," versus the transcendental and rationalist tradition. One of the most important books in American philosophy. Note.

The Western world is in the habit of looking at the history of visual art ‘in closeup’ - single image by single image - and receiving its information about art history in that uniquely particulate form. But if instead we distance ourselves a little from the history of art, enough to see it ‘in long-shot’ as it were - i.e. as a more or less continuous, dense flow of images - patterns emerge in the flow which convey new information, which (...) can sometimes be in direct conflict with long-cherished traditional assumptions. If we use the 25,000 plus year of art history in this way as a ‘barium tracer meal’ for cultural evolution itself, it is unexpectedly revealed as punctuated rather than gradual, driven by alternating phases of open and closed growth in the human ecology, each with its own characteristic pressures of cultural selection. As a result human culture itself has two equally valid but opposite ‘fitness landscapes’: in the past 500 years the more successful strand in Western civilization has been the Type-A low-cohesion/ high-agility culture associated with a phase of open evolution involving our species relatively rapid transition from a manual to a machine ecology. The West’s traditional object-based imagery of painting and sculpture has its origins in that period of accelerating pre-industrial and industrial growth with its characteristic ‘economics of plenty’ epitomized by a triumphant capitalism. But the newly-emergent event-based imagery of installations and contextual art of the later twentieth and early twenty-first century is now indicating the gradual emergence (or more properly re-emergence) of the Type-B high-cohesion/lowagility pattern, previously associated with so-called ‘primitive’ cultures, and here with the global consolidation of our new machine ecology in a world increasingly dominated by the economics of scarcity. If that is so, it is probable that the syncretic form of meaning associated with the ‘sticky memes’ of art will increasingly come to challenge the present cultural dominance of analytic meaning, epitomized by the ‘smooth memes’ of science. The resolution of that conflict in evolutionary semantics may have a direct bearing on our species capacity to survive into the future. Whether it will be more decisively resolved within the Western or the Eastern group of civilizations seems at present a very open question. (shrink)

The Consciousness Reframed proposition is exciting because it is both interdisciplinary and offers the possibility of a macrocosmic perspective on the world – a view of the world as simultaneously a whole in itself, the sum of its parts, and as part of a wider whole – or as Koestler put it, ‘After a period of some 500 years when the western eye has been focussed primarily on the microcosmic, scaling up from the micro to the macro does not at (...) first come easily’. Global civilization has too often been misled by grand narratives – never more so than in the twentieth century, when grand narratives of race and class slugged it out bringing death to millions. On the other hand the planetary ‘big picture’ nowadays forces itself upon us through global information networks that all of us simultaneously share in a time-compact world. As such we are creatures of the macrocosmos, whether we care to acknowledge it or not. The Planetary Collegium, this article suggests, is a beach-head on the shores of a macrocosmos awaiting both discovery and re-discovery. (shrink)

Traditional art history equates the production of the memes of visual art exclusively with individual consciousness. An evolutionary art history looks also at the patterns into which art-memes flow patterns that display striking synchronicities of cultural motivation, both within the arts themselves and between the arts and sciences parallel patterns of collective memetic behaviour. We are all familiar with short-wave collective behaviour: football fans, evangelist meetings, political demonstrations, rioting crowds and panicking troops all display it. This paper is concerned with (...) long-wave collective behaviour, as evidenced in the migration of Western elite culture from the open to the closed meme in the arts and sciences of the Renaissance period, or again in the reciprocal cultural migration from closed to open memes going on in the arts and sciences at the present time. How do we explain this swarming of the memes, such that artistic and scientific communication, despite their explicitly different forms, seem invisibly joined at the hip? Why do our memes rock'n'roll topologically between open and closed states? The paper suggests that memetic swarming the synchronization of our memes in alternating open and closed states may be an expression of the sensitivity of our consciousness to the changing dynamics of our own relationship with the planetary biosphere through ecological evolution. If so, the ultimate driver of memetic swarming may be an algorithm as commonplace and as universal as the figureground opposition: linking our evolution with our memes by way of a simple principle of reciprocity, such that consciousness will tend to output closed memes in periods of open evolution, and, reciprocally, closed memes in periods of open evolution.

Hubert Dreyfus has argued that cases of absorbed bodily coping show that there is no room for self-awareness in flow experiences of experts. In this paper, I argue against Dreyfus’ maxim of vanishing self-awareness by suggesting that awareness of agency is present in expert bodily action. First, I discuss the phenomenon of absorbed bodily coping by discussing flow experiences involved in expert bodily action: merging into the flow; immersion in the flow; emergence out of flow. I argue against the claim (...) that flow experience does not involve an awareness of agency for each of these features, while conceding that fluent agency does not involve self-awareness in the thetic sense. I challenge the assumption that the awareness of fluent agency must be understood in terms of a thetic awareness of agency. Instead, I develop an Anscombean account of the awareness of fluent agency in terms of the phenomenal character of knowing one’s aims. I respond to the challenge that if an Anscombean account of the awareness of agency is to succeed, then agents must be able to answer Anscombean questions. I consider the objection that awareness of agency is not a form of self-awareness by outlining an account of self-awareness as self-synthesis that is distinct from self-perception and self-ascription, but which makes room for self-awareness in expert bodily action.

Do Quine and Carnap distort the social nature of inquiry by privileging individual epistemic subjects? This objection is at the heart of Donald Davidson’s claim that Quine fails to grasp the significance of the concept of truth. In Carnap’s case, the objection may be detected in Charles Morris’s call to ground scientific philosophy in semiotics, the science of signs, rather than syntax, the formal investigation of languages. Drawing out the challenge from Morris’s proposal requires examining a neglected influence on this (...) neglected philosopher: his advisor George Herbert Mead’s social theory of mind. I argue that Morris and Davidson can both be understood as demanding that scientific philosophers socialize their conception of objectivity. (shrink)

For this 1897 publication, the American philosopher William James brought together ten essays, some of which were originally talks given to Ivy League societies. Accessible to a broader audience, these non-technical essays illustrate the author's pragmatic approach to belief and morality, arguing for faith and action in spite of uncertainty. James thought his audiences suffered 'paralysis of their native capacity for faith' while awaiting scientific grounds for belief. His response consisted in an attitude of 'radical empiricism', which deals (...) practically rather than ideologically with real-world phenomena. When facing a 'momentous' decision about belief, he says, we both can and must choose the best hypothesis. The first four essays apply this principle to religious faith, and the rest explore the pragmatic approach to such topics as determinism, ethics and individual achievement. James developed his ideas further in The Varieties of Religious Experience and Pragmatism, both of which are reissued in this series. (shrink)

The Gifford Lectures were established in 1885 at the universities of St Andrews, Glasgow, Aberdeen and Edinburgh to promote the discussion of 'Natural Theology in the widest sense of the term - in other words, the knowledge of God', and some of the world's most influential thinkers have delivered them. The 1901–2 lectures given in Edinburgh by American philosopher William James are considered by many to be the greatest in the series. The lectures were published in book form in (...) 1902 and have been reprinted many times. James, who was educated in the United States and Europe, and spent much of his career teaching philosophy at Harvard, was very influential in the development of modern psychology, and in these twenty lectures he explores the personal experience of religion. Some of the topics include religion and neurology, 'the sick soul', saintliness, and mysticism. (shrink)

In this unique work, James P. Sterba argues that traditional ethics has yet to confront the three significant challenges posed by environmentalism, feminism, and multiculturalism. He maintains that while traditional ethics has been quite successful at dealing with the problems it faces, it has not addressed the possibility that its solutions to these problems are biased in favor of humans, men, and Western culture. In Three Challenges to Ethics: Environmentalism, Feminism, and Multiculturalism, Sterba examines each of these challenges. In (...) the case of environmentalism, he argues that traditional ethics must incorporate conflict resolution principles that favor nonhumans over humans in a significant range of cases. In terms of feminism, he maintains that traditional ethics should rule out gendered family structures and implement an ideal of androgyny. In regard to multiculturalism, he contends that traditional ethics must endorse an ethics that is secular in character and that can survive an extensive comparative evaluation of both Western and non-Western moral ideals and cultures. The only textbook devoted to this topic, Three Challenges to Ethics is an engaging text for introductory courses in ethics and moral problems and is also interesting and provocative reading for scholars and general readers.

Rather than representing a break with his earlier philosophical undertakings, The Birth of Tragedy can be seen as continuous with them and Nietzsche's later works. James Porter argues that Nietzsche's argumentative and writerly strategies resemble his earlier writings on philology in his 'staging' of meaning rather than in his advocacy of various positions. The derivation of the Dionysian from the Apollinian, and the interest in the atomistic challenges to Platonism, are anticipated in earlier works. Also the theory of the (...) all-too-human subject is a thread that runs throughout Nietzsche's oeuvre, critically undoing what his philosophy appears to erect, confirming that Nietzsche is a most unreliable witness to his own meaning. As well as studying the relation of The Birth of Tragedy to later writings, the author examines it on its own terms as a self-standing and complete piece of imagining, with close regard to the self-presentation of the work itself.

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

One of the great American pragmatic philosophers alongside Peirce and Dewey, William James (1842–1910) delivered these eight lectures in Boston and New York in the winter of 1906–7. Though he credits Peirce with coining the term 'pragmatism', James highlights in his subtitle that this 'new name' describes a philosophical temperament as old as Socrates. The pragmatic approach, he says, takes a middle way between rationalism's airy principles and empiricism's hard facts. James' pragmatism is both a method of (...) interpreting ideas by their practical consequences and an epistemology which identifies truths according to their useful outcomes. Furnished with many examples, the lectures illustrate pragmatism's response to classic problems such as the question of free will versus determinism. Published in 1907, this work further develops James's approach to religion and morality, introduced in The Will to Believe (1897) and The Varieties of Religious Experience (1902), both reissued in this series.

Now in a third edition, Introduction to Philosophy: Classical and Contemporary Readings is a highly acclaimed, topically organized collection that covers five major areas of philosophy--theory of knowledge, philosophy of religion, philosophy of mind, freedom and determinism, and moral philosophy. Editor Louis P. Pojman enhances the text's topical organization by arranging the selections into a pro/con format to help students better understand opposing arguments. He also includes accessible introductions to each chapter, subsection, and individual reading, a unique feature for an (...) anthology of this depth. While the book focuses on a compelling sampling of classical material--including selections from Plato, Aristotle, Descartes, Locke, Berkeley, Hume, and Kant--it also incorporates some of philosophy's best twentieth-century and contemporary work, featuring articles by Bertrand Russell, Richard Taylor, John Searle, Thomas Nagel, and others. This third edition contains an expanded glossary, more extensive section introductions, and twelve new selections: Karl Popper: "Epistemology without a Knowing Subject" Richard Rorty: "Dismantling Truth: Solidarity Versus Objectivity" Daniel Dennett: "Postmodernism and Truth" Bruce Russell: "The Problem of Evil: Too Much Suffering" David Chalmers: "Against Materialism: Can Consciousness Be Reductively Explained?"

"Well-being," "welfare," "utility," and "quality of life," all closely related concepts, are at the center of morality, politics, law, and economics. Griffin's book, while primarily a volume of moral philosophy, is relevant to all of these subjects. Griffin offers answers to three central questions about well-being: what is the best way to understand it, can it be measured, and where should it fit in moral and political thought. With its breadth of investigation and depth of insight, this work holds significance (...) for philosophers as well as for those interested in political and economic theory and jurisprudence.

The problem of personal identity is often said to be one of accounting for what it is that gives persons their identity over time. However, once the problem has been construed in these terms, it is plain that too much has already been assumed. For what has been assumed is just that persons do have an identity. A new interpretation of Hume's no-self theory is put forward by arguing for an eliminative rather than a reductive view of personal identity, and (...) by approaching the problem in terms of phenomenology, Buddhist psychology, and the idea of a constructed self-image.

A lineage of prominent philosophers who have discussed the second-person relation can be regarded as advancing structural accounts. They posit that the second-person relation effects one transformative change to the structure of practical reasoning. In this paper, I criticise this orthodoxy and offer an alternative, substantive account. That is, I argue that entering into second-personal relations with others does indeed affect one's practical reasoning, but it does this not by altering the structure of one's agential thought, but by changing what (...) reasons can become available. The importance of second-personal thought for action is heterogenous. Second-person relations make possible the emergence of a wide variety of different kinds of practical reasons: creating some, revealing others. Recognising this diminishes the appeal of the traditional, structural accounts of the practical significance of such second-personal relations. Moving away from structural accounts facilitates a more thorough understanding of the intersubjective form of action. (shrink)

This paper is about the similarity between the appreciation of a piece of art, such as a cherished music album, and the loving appreciation of a person whom one knows well. In philosophical discussion about the rationality of love, the Qualities View (QV) says that love can be justified by reference to the qualities of the beloved. I argue that the oft-rehearsed trading-up objection fails to undermine the QV. The problems typically identified by the objection arise from the idea that (...) love-worthy qualities could be coarse-grained, when in fact they must be fine-grained. The analogy with appreciation of aesthetic qualities helps to draw out this point. Once the fine-grained nature of love-worthy qualities is properly understood, it is clear that critics of the QV cannot rely on the trading-up objection to motivate its rejection. Moreover, the paper’s core argument helps to illuminate the persistently aesthetic nature of interpersonal affections. (shrink)

We applaud the spirit of MacNeilage's attempts to better explain the evolution and cortical control of speech by drawing on the vast literature in nonhuman primate neurobiology. However, he oversimplifies motor cortical fields and their known individual functions to such an extent that he undermines the value of his effort. In particular, MacNeilage has lumped together the functional characteristics across multiple mesial and lateral motor cortex fields, inadvertantly creating two hypothetical centers that simply may not exist.

Sebastian Rödl's Self-Consciousness and Objectivity is one of the most original and thought-provoking books in philosophy of mind for the last several years. An ambitious defence of absolute idealism, Rödl rejects the idea that reality is simply something given, and instead advances the position that all reality is accessible to thought because reality is already included in judgment. In this outstanding collection, a roster of international contributors critically examine the significance of Rödl's arguments and take the themes of his book (...) in new directions. The volume concludes with an extensive response by Sebastian Rödl to his critics, making it essential reading for those interested in contemporary debates in analytic philosophy, philosophy of mind and philosophical idealism.

According to James M. Kauffman, too much of what is said today about educational reform is nonsense that shortchanges students, parents, and taxpayers. This deforms education rather than reforming it. The primary objective of this book is to help teachers, teacher educators, policy makers, and parents think more critically about current rhetoric about education. Reason and science in the enlightenment tradition are more helpful in reforming and improving education than political agendas. Reform should focus on instruction. Education must address (...) the full range of learners, from those who are mentally retarded to those who are intellectually gifted. Special education, multicultural education, and standardized testing are among the controversial issues explored. Extremes of both left and right ideologies are rejected in favor of careful thinking and sound judgment. (shrink)

Software application ontologies have the potential to become the keystone in state-of-the-art information management techniques. It is expected that these ontologies will support the sort of reasoning power required to navigate large and complex terminologies correctly and efficiently. Yet, there is one problem in particular that continues to stand in our way. As these terminological structures increase in size and complexity, and the drive to integrate them inevitably swells, it is clear that the level of consistency required for such navigation (...) will become correspondingly difficult to maintain. While descriptive semantic representations are certainly a necessary component to any adequate ontology-based system, so long as ontology engineers rely solely on semantic information, without a sound ontological theory informing their modeling decisions, this goal will surely remain out of reach. In this paper we describe how Language and Computing nv (L&C), along with The Institute for Formal Ontology and Medical Information Sciences (IFOMIS), are working towards developing and implementing just such a theory, combining the open software architecture of L&C’s LinkSuiteTM with the philosophical rigor of IFOMIS’s Basic Formal Ontology. In this way we aim to move beyond the more or less simple controlled vocabularies that have dominated the industry to date. (shrink)

Why are natural theories pre-well-ordered by consistency strength? In previous work, an approach to this question was proposed. This approach was inspired by Martin's Conjecture, one of the most prominent conjectures in recursion theory. Fixing a reasonable subsystem $T$ of arithmetic, the goal was to classify the recursive functions that are monotone with respect to the Lindenbaum algebra of $T$. According to an optimistic conjecture, roughly, every such function must be equivalent to an iterate $\mathsf{Con}_T^\alpha$ of the consistency operator ``in (...) the limit'' within the ultrafilter of sentences that are true in the standard model. In previous work the author established the first case of this optimistic conjecture; roughly, every recursive monotone function is either as weak as the identity operator in the limit or as strong as $\mathsf{Con}_T$ in the limit. Yet in this note we prove that this optimistic conjecture fails already at the next step; there are recursive monotone functions that are neither as weak as $\mathsf{Con}_T$ in the limit nor as strong as $\mathsf{Con}_T^2$ in the limit. In fact, for every $\alpha$, we produce a function that is cofinally equivalent to $\mathsf{Con}^\alpha_T$ yet cofinally equivalent to $\mathsf{Con}_T$. (shrink)

Our lives are dominated by technology. We live with and through the achievements of technology. What is true of the rest of life is of course true of medicine. Many of us owe our existence and our continued vigour to some achievement of medical technology. And what is true in a major way of general medicine is to a significant degree true of psychiatry. Prozac has long since arrived, and in its wake an ever-growing armamentarium of new psychotropics; beyond that, (...) neuroscience promises ever more technological advances for the field. -/- However, the effect of technology on the field of psychiatry remains highly ambiguous. On the one hand there are the achievements, both in the science and practice of psychiatry; on the other hand technology's influence on the field threatens its identity as a humanistic practice. In this ambiguity psychiatry is not unique - major thinkers have for a long time been highly ambivalent and concerned about the technological order that now defines modern society. For the future, the danger is that the psychiatrically real becomes that which can be seen, the symptom, and especially that which can be measured. Disorders and treatments might become reduced to what can be defined by diagnostic criteria and what can be mapped out on a scale. -/- This book exams how technology has come to influence and drive psychiatry forward, and considers at just what cost these developments have been made. It includes a range of stimulating and thought-provoking chapters from a range of psychiatrists and philosophers. (shrink)

Axel Honneth has been instrumental in advancing the work of the Frankfurt School of critical theorists, rebuilding their effort to combine radical social and political analysis with rigorous philosophical inquiry. These eleven essays published over the past five years reclaim the relevant themes of the Frankfurt School, which counted Theodor W. Adorno, Max Horkheimer, Walter Benjamin, Jürgen Habermas, Franz Neumann, and Albrecht Wellmer as members. They also engage with Kant, Freud, Alexander Mitscherlich, and Michael Walzer, whose work on morality, history, (...) democracy, and individuality intersects with the Frankfurt School's core concerns. Collected here for the first time in English, Honneth's essays pursue the unifying themes and theses that support the methodologies and thematics of critical social theory, and they address the possibilities of continuing this tradition through radically changed theoretical and social conditions. According to Honneth, there is a unity that underlies critical theory's multiple approaches: the way in which reason is both distorted and furthered in contemporary capitalist society. And while much is dead in the social and psychological doctrines of critical social theory, its central inquiries remain vitally relevant. Is social progress still possible after the horrors of the twentieth century? Does capitalism deform reason and, if so, in what respects? Can we justify the relationship between law and violence in secular terms, or is it inextricably bound to divine justice? How can we be free when we're subject to socialization in a highly complex and in many respects unfree society? For Honneth, suffering and moral struggle are departure points for a new "reconstructive" form of social criticism, one that is based solidly in the empirically grounded, interdisciplinary approach of the Frankfurt School.
