Hubert Dreyfus

(1929 - 2017)

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.

This article traces the trajectory of Heidegger’s thinking about technology over the course of what is considered to be his early, middle, and late periods. Over the course of the years, Heidegger’s concerns moved from somewhat conventional concerns over the consumerism technology entails, and the damage it causes to the environment, to the more complex position that technicity distorts human nature with an accompanying loss of meaning. The real danger, he said, is not the destruction of nature or culture, nor selfindulgent consumerism, but a new totalizing style of practices that would restrict our openness to people and things by driving out all other styles of practice that enable us to be receptive to realty.

This seminal early work of Foucault is indispensable to understanding his development as a thinker. Written in 1954 and revised in 1962, _Mental Illness and Psychology _delineates the shift that occurred in Foucault's thought during this period. The first iteration reflects the philosopher's early interest in and respect for Freud and the psychoanalytic tradition. The second part, rewritten in 1962, marks a dramatic change in Foucault's thinking. Examining the history of madness as a social and cultural construct, he moves outside of the psychoanalytic tradition into the radical critique of Freud that was to dominate his later work. _Mental Illness and Psychology _is an important document tracing the intellectual evolution of this influential thinker. A foreword by Foucault scholar Hubert Dreyfus situates the book within the framework of Foucault's entire body of work.

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"

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.

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.

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.

Martin Heidegger's major work, Being and Time, is usually considered the culminating work in a tradition called existential philosophy. The first person to call himself an existential thinker was Soren Kierkegaard, and his influence is clearly evident in Heidegger's thought. Existential thinking rejects the traditional philosophical view, that goes back to Plato at least, that philosophy must be done from a detached, disinterested point of view. Kierkegaard argues that our primary access to reality is through our involved action. The way things show up for a detached thinker is a partial and distorted version of the way things show up to a committed individual.
