Hubert Dreyfus

(1929 - 2017)

Actual AI research began auspiciously around 1955 with Allen Newell and Herbert Simon's work at the RAND Corporation. Newell and Simon proved that computers could do more than calculate. They demonstrated that computers were physical symbol systems whose symbols could be made to stand for anything, including features of the real world, and whose programs could be used as rules for relating these features. In this way computers could be used to simulate certain important aspects intelligence. Thus the information-processing model of the mind was born. But, looking back over these fifty years, it seems that theoretical AI with its promise of a robot like HAL appears to be a perfect example of what Imre Lakatos has called a "degenerating research program"

Samuel Todes’s book, Body and World, makes an important contribution to the current debate among analytic philosophers concerning non–conceptual intentional content and its relation to thought. Todes’s relevant theses are: (1) Our unified, active body, in moving to meet our needs, generates a unified, spatio–temporal field. (2) In that field we use our perceptual skills to make the determinable perceptual objects that show up relatively determinate. (3) Once we have made the objects of practical perception determinate, we can make ‘practical perceptual judgements’ about them. Such ‘judgements’ have conditions of satisfaction, but they are non–conceptual in that they are a way of coping with an actual object in this situation, from this point of view, in this light, in this orientation, and so forth. (4) By withholding our activity, however, we can transform our practical perception into a detached, spectatorial perception of qualities that are experienced as independent of the object they qualify. (5) Thanks to our conceptual imagination, we can then treat these qualities as reidentifiable properties of reidentifiable objects that can be entertained by thought.

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.

I shall translate Kierkegaard's account of the dangers and opportunities of what he called the Press into a critique of the Internet so as to raise the question: what contribution -- for good or ill -- can the World Wide Web, with its ability to deliver vast amounts of information to users all over the world, make to educators trying to pass on knowledge and to develop skills and wisdom in their students? I will then use Kierkegaard's three-stage answer to the problem of lack of involvement posed by the Press -- his claim that to have a meaningful life the learner must pass through the aesthetic, the ethical and the religious spheres of existence -- to suggest that only the first two stages -- the aesthetic and the ethical -- can be implemented with Information Technology, while the final stage, which alone makes meaningful learning possible, is undermined rather than supported by the tendencies of the desituated and anonymous Net.

Heidegger and the study of his thought have earned wide acceptance, extending beyond philosophy to influence an array of other disciplines. Critically selected by leading scholars in the field, the articles in this new collection bring together the most essential and representative scholarship on Heidegger. Focusing on the major phases of his work which attracted most attention from contemporary thinkers, as well as exploring new and important areas of Heidegger scholarship, this four-volume set is an invaluable resource for any curriculum supporting philosophy, as well as political theory, literature, classics, anthropology, and cultural studies. This volume is available on its own or as part of the four-volume set, Heidegger Reexamined. For a complete list of the volume titles in this set, see the listing for Heidegger Reexamined [ISBN: 0-415-94041-9].

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.

From his earliest published work, Mental Illness and Personality (1954), to his last project, The History of Sexuality, Foucault was critical of the human sciences as a dubious and dangerous attempt to model a science of human beings on the natural sciences. He therefore preferred existential therapy, which did not attempt to give a causal account of human nature, but rather described the general structure of the human way of being and its possible distortions. Foucault focused his attack on psychiatry, which claimed to have an explanation of normal and abnormal functioning of the personality modeled on medicine. Freud typified for him this deep mistake which he traced first to the Kantian understanding of human beings as transcendental/ empirical doubles which must think their own unthought, and then later to the gradually developing confessional practices which lead people in our culture to try unsuccessfully to put all their desires into words so as to conform to the norms of psychoanalysis which in turn are based on an account of sexuality as a cause of personality. Foucault proposed his genealogical account of how our culture arrived at this view of man as sexual being as a form of therapy which was to help us free ourselves from this restrictive self- interpretation.

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.

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

This paper analyzes Kierkegaard's Religiousness A sphere of existence, presented in his edifying works, and Heidegger's concept of authenticity, proposed in Being and Time, as responses to modern nihilism. While Kierkegaard argues that Religiousness A is an unsuccessful response to modern nihilism, Heidegger claims that authenticity, a secularized version of Religiousness A, is a successful response. We argue that Heidegger's secularization of Religiousness A is incomplete and unsuccessful, that Heidegger's later work offers a reconsideration of the problem of modern nihilism, and that later Heidegger suggests a way out of nihilism which is compatible with Kierkegaard's Religiousness B sphere of existence.

We argue that heterophenomenology both over- and under-populates the intentional realm. For example, when one is involved in coping, one’s mind does not contain beliefs. Since the heterophenomenologist interprets all intentional commitment as belief, he necessarily overgenerates the belief contents of the mind. Since beliefs cannot capture the normative aspect of coping and perceiving, any method, such as heterophenomenology, that allows for only beliefs is guaranteed not only to overgenerate beliefs but also to undergenerate other kinds of intentional phenomena.
