This paper is a critical examination of Harry Collins's investigation into a third form of knowledge, “interactional expertise.” We argue that although Collins makes a genuine contribution to the phenomenological literature on expertise, his account requires further critical evaluation and response due to pragmatic and ontological considerations. We contend that by refining (in some questionable ways) the category of interactional expertise so as to create epistemological equivalence between activists, sociologists, critics, journalists, and some science administrators, Collins potentially undermines the value (...) that a more rigorously construed concept of interactional expertise might have. We further show that Collins misunderstands the nature of embodiment in a way that is exacerbated by the sociological perspective that he adopts. (shrink)

In this four part exchange, Evan Selinger starts by stating that Collins’s empirical evidence in respect of linguistic socialization and its bearing on artificial intelligence and expertise is valuable; it advances philosophical and sociological understanding of the relationship between knowledge and language. Nevertheless, he argues that Collins mischaracterizes the data under review and thereby misrepresents how knowledge is acquired and understates the extent to which expert knowers are embodied. Selinger reconstructs the case for the importance of the body in the (...) initial acquisition of language and challenges Collins to show how a disembodied entity could become fluent in any language at all.Collins responds by accepting that his approach does not demonstrate quite as much about the irrelevance of the body as he thought it did but that even though he accepts all of Selinger’s claims, ‘the body’ as needed by the philosophical approach set out by Selinger is still a vestigial thing. Collins’s main point, however, is that the philosophical view of the body—the world is divided into embodied agents and unembodied entities—distracts attention from the more interesting empirically researchable question of how the ability to become socialized diminishes, if it does, as the body become more and more minimal. The right research question is not about whether a person can extrapolate from minimal sensory input but how much extrapolation is possible under different circumstances and how it is done.Dreyfus, having seen the whole of the exchange so far, agrees that both have a point but argues that Collins’s approach still misses the well established importance of bodily engagement for full understanding.Collins responds to this by trying to set out more clearly the position associated with the idea of interactional expertise.Keywords: Interactional expertise; Phenomenology; Turing test; Embodiment; Tacit knowledge; Socialization.

Harry Collins interprets Hubert Dreyfus’s philosophy of embodiment as a criticism of all possible forms of artificial intelligence. I argue that this characterization is inaccurate and predicated upon a misunderstanding of the relevance of phenomenology for empirical scientific research.

In disciplines traditionally studying expertise such as sociology, philosophy, and pedagogy, discussions of demarcation criteria typically centre on how and why human expertise differs from the expertise of artificial expert systems. Therefore, the demarcation criteria has been drawn between robots as formalized logical architectures and humans as creative, social subjects, creating a bipartite division that leaves out animals. However, by downsizing the discussion of animal cognition and implicitly intuiting assimilation of living organisms to robots, key features to explain why human (...) expertise is crucially different from robot expertise are neglected. In the absence of clarification of fundamental cognitive principles of LOs, cognitively robots may appear persuasively closer to humans when they are in fact not. In this paper, I will discuss essential features of organic cognition to emphasise why animals are not like robots at all. The purpose is to add a third category when comparing humans and robots to make a tripartite division that consists of humans LOs, and machines. I will argue that LOs, adapted to ever-changing circumstances, are qualitatively different from robots. Humans, in the sense of belonging to the biological class of LOs, also share this central feature. In addition, however, humans alone possess and use language in a way that turns cognition from a predominantly online to off-line activity, 625–635 2002) that introduces truly abstract thinking. In the end I introduce the concept of ‘Linguification’ to dissect the particular mechanisms sustaining abstract thinking in the explanation of what makes humans distinct from robots and LOs.

Expertise depends on hours and hours of practice within a field before a state of proficiency is achieved. Normally, expert skills involve bodily knowledge associated to the practices of a field. Interactional expertise, i.e. the ability to talk competently about the field, however, is not causally dependent on bodily proficiency. Instead, interactional experts are verbally skilled to an extent that makes them impossible to distinguish from so-called contributory experts, the experienced practitioners. The concept of interactional expertise defines linguistic skills as (...) contingent on bodily knowledge. However, recent neuropsychological findings make it plausible that “first-person”-related neural activations would be relevant with respect to the subjects' verbal output, at least when subjects address concepts that refer to tangible objects. Using imitation games, we explore and expand on the apparently arbitrary relation between bodily experiences and linguistic skills in midwifery. In alignment with several findings within grounded cognition studies, the results presented suggest that somehow personal experiences make a linguistic difference, noticeable to contributory experts.

Interactional expertise is said to be a form of knowledge achieved in a linguistic community and, therefore, obtained entirely outside practice. Supposedly, it is not or only minimally sustained by the so-called embodied knowledge. Here, drawing upon studies in contemporary neuroscience and cognitive psychology, I propose that ‘derived’ embodiment is deeply involved in competent language use and, therefore, also in interactional expertise. My argument consists of two parts. First, I argue for a strong relationship among language acquisition, language use and (...) the real world (i.e. the world accessible to the senses). Biological constraints in very early childhood anchor language to the body. These constraints are by-products of our evolutionary peculiarity that we gain because of our physical and psychological immaturity at birth. Thus, infancy is predominantly concerned with the bodily needs and experiences of the concrete while language acquisition takes place. Particular interest in the concrete furnishes our linguistic world and installs ‘concrete’ language as the principal constituent of competent language use. Second, I argue that well-established concrete language implicitly and explicitly elicits mental representations, namely partial reactivations of sensorimotor states that occur during experience. These are stepping stones by which we subsequently make sense of expressions in new linguistic areas. Like any competent language user, the interactional expert, therefore, prompts multimodal imagination and re-enacts concrete experiences when acquiring linguistic knowledge pertaining to a specialist field. Finally, I outline the characteristics of those imaginative powers to identify mechanisms that improve interactional expertise and discuss the obvious relation between interactional expertise and ordinary knowledge acquisition after the concrete language stage.

One of us coined the notion of an “epistemology engine.” The idea is that some particular technology in its workings and use is seen suggestively as a metaphor for the human subject and often for the production of knowledge itself. In this essay, we further develop the conceptand claim that Merleau-Ponty’s phenomenological commitments, although suggestive, did not lead him to appreciate the epistemological value of materiality. We also take steps towards establishing how an understanding of this topic can provide the (...) basis for reinterpreting the history of phenomenology. (shrink)

The embodied, embedded, enactive, and extended approaches to cognition explicate many important details for a phenomenology of perception, and are consistent with some of the traditional phenomenological analyses. Theorists working in these areas, however, often fail to provide an account of how intersubjectivity might relate to perception. This paper suggests some ways in which intersubjectivity is important for an adequate account of perception.

Between formal propositional knowledge and embodied skill lies ‘interactional expertise’—the ability to converse expertly about a practical skill or expertise, but without being able to practice it, learned through linguistic socialisation among the practitioners. Interactional expertise is exhibited by sociologists of scientific knowledge, by scientists themselves and by a large range of other actors. Attention is drawn to the distinction between the social and the individual embodiment theses: a language does depend on the form of the bodies of its members (...) but an individual within that community can learn the language without the body. The idea has significance for our understanding of colour-blindness, deafness and other abilities and disabilities. They say that love's a word. (shrink)

Here I try to improve on the available answers to certain long-debated questions and set out some consequences for the answers. Are there limits to the extent to which we can understand the conceptual worlds of other human communities and of non-human creatures? How does this question relate to our ability to engage in other cultures’ practices and languages? What is meant by ‘the body’ and what is meant by ‘the brain’ and how do different meanings bear on the questions? (...) The central answer developed here is that it is possible, given the right circumstances, for a competent human from any human group to understand the culture of any other human group without engaging in their practices though there are barriers when it comes to communication across species. This answer has important social and political consequences and consequences for the debate about artificial intelligence. (shrink)

How the Body Shapes the Mind is an interdisciplinary work that addresses philosophical questions by appealing to evidence found in experimental psychology, neuroscience, studies of pathologies, and developmental psychology. There is a growing consensus across these disciplines that the contribution of embodiment to cognition is inescapable. Because this insight has been developed across a variety of disciplines, however, there is still a need to develop a common vocabulary that is capable of integrating discussions of brain mechanisms in neuroscience, behavioural expressions (...) in psychology, design concerns in artificial intelligence and robotics, and debates about embodied experience in the phenomenology and philosophy of mind. Shaun Gallagher's book aims to contribute to the formulation of that common vocabulary and to develop a conceptual framework that will avoid both the overly reductionistic approaches that explain everything in terms of bottom-up neuronal mechanisms, and inflationistic approaches that explain everything in terms of Cartesian, top-down cognitive states. Gallagher pursues two basic sets of questions. The first set consists of questions about the phenomenal aspects of the structure of experience, and specifically the relatively regular and constant features that we find in the content of our experience. If throughout conscious experience there is a constant reference to one's own body, even if this is a recessive or marginal awareness, then that reference constitutes a structural feature of the phenomenal field of consciousness, part of a framework that is likely to determine or influence all other aspects of experience. The second set of questions concerns aspects of the structure of experience that are more hidden, those that may be more difficult to get at because they happen before we know it. They do not normally enter into the content of experience in an explicit way, and are often inaccessible to reflective consciousness. To what extent, and in what ways, are consciousness and cognitive processes, which include experiences related to perception, memory, imagination, belief, judgement, and so forth, shaped or structured by the fact that they are embodied in this way?

This paper argues that self-consciousness and moral agency depend crucially on both embodied and social aspects of human existence, and that the capacity for practical wisdom, phronesis, is central to moral personhood. The nature of practical wisdom is elucidated by drawing on rival analyses of expertise. Although ethical expertise and practical wisdom differ importantly, they are alike in that we can acquire them only in interaction with other persons and through habituation. The analysis of moral agency and practical wisdom is (...) framed by Dennett's proposal that moral personhood requires satisfaction of six conditions, including self-consciousness. (shrink)
