This book is the first to provide a sustained, coherent analysis of Foucault's work as a whole. To demonstrate the sense in which Foucault's work is beyond structuralism and hermeneutics, the authors unfold a careful, analytical exposition of his oeuvre. They argue that during the of Foucault's work became a sustained and largely successful effort to develop a new method - "interpretative analytics" - capable of explaining both the logic of structuralism's claim to be an objective science and the apparent (...) validity of the hermeneutical counterclaim that the human sciences can proceed only by understanding the deepest meaning of the subject and his tradition.

McDowell's claim that "in mature human beings, embodied coping is permeated with mindedness",1 suggests a new version of the mentalist myth which, like the others, is untrue to the phenomenon. The phenomena show that embodied skills, when we are fully absorbed in enacting them, have a kind of non-mental content that is non-conceptual, non-propositional, non-rational and non-linguistic. This is not to deny that we can monitor our activity while performing it. For solving problems, learning a new skill, receiving coaching, and (...) so forth, such monitoring is invaluable. But monitoring what we are doing as we are doing it degrades performance to at best competence. On McDowell's view, there is no way to account for such a degradation in performance since the same sort of content would be involved whether we were fully absorbed in or paying attention to what we were doing. McDowell claims that it is an advantage of his conceptualism that it avoids any foundationalist attempt to build up the objective world on the basis of an indubitable Given or any other ground-floor experience. And, indeed, if the world is all that is the case and our minds are unproblematically open to it, all experience is on the same footing. But one must distinguish motor intentionality, and the interrelated solicitations our coping body is intertwined with, from conceptual intentionality and the world of propositional structures it opens onto. The existential phenomenologist can then agree with McDowell in rejecting traditional foundationalisms, while yet affirming and describing the ground-floor role of motor intentionality in providing the support on which all forms of conceptual intentionality are based.

Existential phenomenologists hold that the two most basic forms of intelligent behavior, learning, and skillful action, can be described and explained without recourse to mind or brain representations. This claim is expressed in two central notions in Merleau-Ponty's Phenomenology of Perception: the intentional arc and the tendency to achieve a maximal grip. The intentional arc names the tight connection between body and world, such that, as the active body acquires skills, those skills are “stored”, not as representations in the mind, (...) but as dispositions to respond to the solicitations of situations in the world. A phenomenology of skill acquisition confirms that, as one acquires expertise, the acquired know-how is experienced as finer and finer discriminations of situations paired with the appropriate response to each. Maximal grip names the body's tendency to refine its responses so as to bring the current situation closer to an optimal gestalt. Thus, successful learning and action do not require propositional mental representations. They do not require semantically interpretable brain representations either.Simulated neural networks exhibit crucial structural features of the intentional arc, and Walter Freeman's account of the brain dynamics underlying perception and action is structurally isomorphic with Merleau-Ponty's account of the way a skilled agent is led by the situation to move towards obtaining a maximal grip.

_Internet_ is een van de eerste boeken waarin het filosofische inzicht -van Plato tot Kierkegaard - betrokken wordt op het debat over de mogelijkheden en onmogelijkheden van het internet. Dreyfus laat zien dat de onstoffelijke, 'vrij zwevende' websurfer zijn oorsprong vindt in Descartes' scheiding van geest en lichaam, en hoe Kierkegaards inzichten in de opkomst van het moderne leespubliek vooruitlopen op de nieuwsgierige, maar elk risico vermijdende internet-junkie. Uitgaande van recente onderzoeken naar het isolement dat veel internetgebruikers ervaren, toont Dreyfus (...) aan hoe het internet, door zijn nadruk op privé-ervaringen, gebruikers berooft van wezenlijke, belichaamde vermogens zoals vertrouwen, stemmingen en betrokkenheid bij met anderen gedeelde lokale aangelegenheden. _Internet_ is verplichte kost voor iedereen die on line is en is geïnteressseerd in onze plaats in de 'e-revolutie'.

Back in 1950, while a physics major at Harvard, I wandered into C.I. Lewis’s epistemology course. There, Lewis was confidently expounding the need for an indubitable Given to ground knowledge, and he was explaining where that ground was to be found. I was so impressed that I immediately switched majors from ungrounded physics to grounded philosophy.
Our contemporary nihilism -- Homer's polytheism -- From Aeschylus to Augustine : monotheism on the rise -- From Dante to Kant : the attractions and dangers of autonomy -- Fanaticism, polytheism, and Melville's "evil art" -- David Foster Wallace's nihilism -- Conclusion : lives worth living in a secular age.
In previous work I urged that the perceptual experience we rational animals enjoy is informed by capacities that belong to our rationality, and - in passing - that something similar holds for our intentional action. In his Presidential Address, Hubert Dreyfus argued that I thereby embraced a myth, "the Myth of the Mental". According to Dreyfus, I cannot accommodate the phenomenology of unreflective bodily coping, and its importance as a background for the conceptual capacities exercised in reflective intellectual activity. My (...) paper responds to this accusation. Dreyfus misreads my invocation of Aristotle, and is thereby led to suppose, wrongly, that I conceive rationality as detached, brought to bear on practical predicaments from a standpoint other than one of immersion in them. I urge that even unreflective bodily coping, on the part of rational animals, is informed by their rationality. Dreyfus mentions Heidegger’s distinction, which is picked up by Gadamer, between being oriented towards the world and merely inhabiting an environment. But he sets it aside, whereas it is crucial for the issue between us. Engaged bodily coping involves responsiveness to affordances, and responsiveness to affordances on the part of rational animals belongs to their relation to the world. I explain how the idea that conceptual capacities are actualized in our perceptual experience is connected with the thought that our perceptual experience opens us to the world. Finally, I suggest that the real myth in this area is the conception of rationality underlying Dreyfus’s resistance to my picture. (shrink)
Can we accept John McDowell’s Kantian claim that perception is conceptual “all the way out,” thereby denying the more basic perceptual capacities we seem to share with prelinguistic infants and higher animals? More generally, can philosophers successfully describe the conceptual upper floors of the edifice of knowledge while ignoring the embodied coping going on on the ground floor? I argue that we shouldn’t leave the conceptual component of our lives hanging in midair and suggest how philosophers who want to understand (...) knowledge and action can profit from a phenomenological analysis of the nonconceptual embodied coping skills we share with animals and infants, as well as the nonconceptual immediate intuitive understanding exhibited by experts.

For fifty years Hubert Dreyfus has done pioneering work which brings phenomenology and existentialism to bear on the philosophical and scientific study of the mind. This is a selection of his most influential essays, developing his critique of the representational model of the mind in analytical philosophy of mind and mainstream cognitive science.

Body and World is the definitive edition of a book that shouldnow take its place as a major contribution to contemporary existentialphenomenology. Samuel Todes goes beyond Martin Heidegger and MauriceMerleau-Ponty in his description of how independent physical natureand experience are united in our bodily action. His account allows himto preserve the authority of experience while avoiding the tendencytoward idealism that threatens both Heidegger and Merleau-Ponty.Todes emphasizes the complex structure of the human body ;front/back asymmetry, the need to balance in a (...) gravitational field, and so forth ;and the role that structure plays in producing the spatiotemporal field of experience and in making possible objective knowledge of the objects in it. He shows that perception involves nonconceptual, but nonetheless objective forms of judgment. One can think of Body and World as fleshing out Merleau-Ponty's project while presciently relating it to the current interest in embodiment, not only in philosophy but also in psychology, linguistics, cognitive science, artificial intelligence, neuroscience, and anthropology. Todes's work opens new ways of thinking about problems such as the relation of perception to thought and the possibility of knowing an independent reality ;problems that have occupied philosophers since Kant and still concern analytic and continental philosophy.

In this paper I would like to explain, defend, and draw out the implications of this claim. Since the intentional arc is supposed to embody the interconnection of skillful action and perception, I will first lay out an account of skill.
Ways of the Hand tells the story of how David Sudnow learned to improvise jazz on the piano. Because he had been trained as an ethnographer and social psychologist, Sudnow was attentive to what he experienced in ways that other novice pianists are not. The result, first published in 1978 and now considered by many to be a classic, was arguably the finest and most detailed account of skill development ever published.Looking back after more than twenty years, Sudnow was struck (...) by the extent to which he had allowed his academic background to shape the book's language. He realized that he could now do a much better job of describing his experiences in a way that would not require facility with formal social science and philosophical discourse. The result is a revised version of the book that carries the same intellectual energy as the original but is accessible to a much wider audience. (shrink)

Against Davidsonian (or deflationary) realism, it is argued that it is coherent to believe that science can in principle give us access to the functional components of the universe as they are in themselves in distinction from how they appear to us on the basis of our quotidian concerns or sensory capacities. The first section presents the deflationary realist's argument against independence. The second section then shows that, although Heidegger pioneered the deflationary realist account of the everyday, he sought to (...) establish a robust realist account of science. Next, the third section develops two different sides of Heidegger's thinking. Resources developed by Thomas Kuhn are drawn on to work out Heidegger's account of plural worlds. This argument shows that it makes sense to talk about things-in-themselves independent of our practices, but falls short of the robust realist claim that we can have access to things as they are in themselves independent of our practices. So, secondly, Saul Kripke's account of rigid designation is drawn on to work out Heidegger's account of formal designation. On the basis of a Heideggerian elaboration of rigid designation, it is argued that we do indeed have practices for achieving access to things independent of all our practices. But this second argument leaves us unable to reject metaphysical nominalism. So, thirdly, it is proposed that the currently most persuasive philosophical argument for nominalism depends on a logico-mathematical space of possibilities. But the proto-theoretical space opened by the pre-scientific access practices has features that provide reasons for believing that the independent stuff to which we have access has a determinate structure and specific causal powers.

being, culminating in the technological understanding of being, in order to help us understand and overcome our current way of dealing with things as objects and resources, Foucault analyzes several regimes of power, culminating in modern bio-power, in order to help us free ourselves from understanding ourselves as subjects.
Husserl and Searle agree that, for a bodily movement to be an action, it must be caused by a propositional representation. Husserl's representation is a mental state whose intentional content is what the agent is trying to do; Searle thinks of the representation as a logical structure expressing the action's conditions of satisfaction. Merleau-Ponty criticises both views by introducing a kind of activity he calls motor intentionality, in which the agent, rather than aiming at success, feels drawn to reduce a (...) felt tension. I argue that Searle can account for Merleau-Ponty's kind of coping only by broadening his notion of propositional representation to include indexicals, but that, in so doing, he covers up the way representational intentionality depends upon motor intentionality.

In their debate over my interpretation of Heidegger's account of das Man in Being and Time, Frederick Olafson and Taylor Carman agree that Heidegger's various characterizations of das Man are inconsistent. Olafson champions an existentialist/ontic account of das Man as a distorted mode of being?with. Carman defends a Wittgensteinian/ontological account of das Man as Heidegger's name for the social norms that make possible everyday intelligibility. For Olafson, then, das Man is a privative mode of Dasein, while for Carman it makes (...) up an important aspect of Dasein's positive constitution. Neither interpreter takes seriously the other's account, though both acknowledge both readings are possible. How should one choose between these two interpretations? I suggest that we choose the interpretation that identifies the phenomenon the work is examining, gives the most internally consistent account of that phenomenon, and shows the compatibility of this account with the rest of the work.

In the 1960s, without realizing it, AI researchers were hard at work finding the features, rules, and representations needed for turning rationalist philosophy into a research program, and by so doing AI researchers condemned their enterprise to failure. About the same time, a logician, Yehoshua Bar-Hillel, pointed out that AI optimism was based on what he called the “first step fallacy”. First step thinking has the idea of a successful last step built in. Limited early success, however, is not a (...) valid basis for predicting the ultimate success of one’s project. Climbing a hill should not give one any assurance that if he keeps going he will reach the sky. Perhaps one may have overlooked some serious problem lying ahead. There is, in fact, no reason to think that we are making progress towards AI or, indeed, that AI is even possible, in which case claiming incremental progress towards it would make no sense. In current excited waiting for the singularity, religion and technology converge. Hard headed materialists desperately yearn for a world where our bodies no longer have to grow old and die. They will be transformed into information, like Google digitizes old books, and we will achieve the promise of eternal life. As an existential philosopher, however, I suggest that we may have to overcome the desperate desire to digitalize our bodies so as to achieve immortality, and, instead, face up to and maybe even enjoy our embodied finitude.

Artificial Intelligence, and the cognitivist view of mind on which it is based, represent the last stage of the rationalist tradition in philosophy. This tradition begins when Socrates assumes that intelligence is based on principles and when Plato adds the requirement that these principles must be strict rules, not based on taken-for-granted background understanding. This philosophical position, refined by Hobbes, Descartes and Leibniz, is finally converted into a research program by Herbert Simon and Allen Newell. That research program is now (...) in trouble, so we must return to its source and question Socrates' assumption that intelligence consists in solving problems by following rules, and that one acquires the necessary rules by abstracting them from specific cases. A phenomenological description of skill acquisition suggests that the acquisition of expertise moves in just the opposite direction: from abstract rules to particular cases. This description of expertise accounts for the difficulties that have confronted AI for the last decade. (shrink)
We assume that acting ethically is a skill. We then use a phenomenological description of five stages of skill acquisition to argue that an ethics based on principles corresponds to a beginner’s reliance on rules and so is developmentally inferior to an ethics based on expert response that claims that, after long experience, the ethical expert learns to respond appropriately to each unique situation. The skills model thus supports an ethics of situated involvement such as that of Aristotle, John Dewey, (...) and Carol Gilligan against the detached, rationalist ethics of Kant, John Rawls, Lawrence Kohlberg, and Jürgen Habermas.

IN SEPTEMBER 1957, Herbert Simon, a pioneer in cognitive simulation, predicted that within ten years, i.e., by now, a computer would be world chess champion and would prove an important mathematical theorem. This prediction was based on Simon's early initial success in writing a program that could play legal chess and one able to prove simple theorems in logic and geometry. But the early successes turned out to be based on the solution of problems that were simple for machines, and (...) further progress turned out to be more and more difficult, until recently it has begun to be obvious to interested observers, and even to some workers in the field, that the original optimism of Simon and company was unfounded.

Cultural devastation, and the proper response to it, is the central concern of "Radical Hope". I address an uncertainty in Lear's book, reflected in a wavering over the difference between a culture's way of life becoming impossible and its way of life becoming unintelligible. At his best, Lear asks the radical ontological question: when the cultural collapse is such that the old way of life has become not only impossible but retroactively unimaginable,—when nothing one can do makes sense anymore,—how can (...) one go on? In raising this question, Lear's book is a remarkable breakthrough; it comes close to raising the crucial ontological question of how to deal with the total collapse of a culture, and it may well become a classic by starting a conversation on the question: How should we live when our own culture is in the process of actually collapsing? Lear suggests that [w]hat would be required... would be a new Crow poet: one who could take up the Crow past and—rather than use it for nostalgia or ersatz mimesis—project it into vibrant new ways for the Crow to live and to be. Later Heidegger had a similar suggestion for us and I try to spell it out briefly. (shrink)
