Biological processes are often explained by identifying the underlying mechanisms that generate a phenomenon of interest. I characterize a basic account of mechanistic explanation and then present three challenges to this account, illustrated with examples from molecular biology. The basic mechanistic account is insufficient for explaining nonsequential and nonlinear dynamic processes, is insufficient for explaining the inherently stochastic nature of many biological mechanisms, and fails to give a proper framework for analyzing organization. I suggest that biological processes are best approached (...) as a multidimensional gradient—with some processes being paradigmatic cases of mechanisms and some being marginal cases. (shrink)

Lynch et al., in an article in this issue, argue that an entire microbiome is rarely, if ever, the right target of analysis for causal explanations in microbiome research. They argue, using interventionist criteria of proportionality, specificity and stability, for restricting causal claims to the smallest subset of microbes—a causal core—that generate the effect of interest. A further question remains: what kind of interactions generate a consortium of microbes that can operate as causal agents in this manner? Here I introduce (...) two possible kinds of such consortia: ‘trojan horses’ and ‘syntrophic’ individuals. (shrink)

The article presents five fifteenth- to sixteenth-century Pali inscriptions from Sukhodaya, Thailand. Three of them are engraved in the Khom alphabet on large square stone slabs, with considerable attention to format; they seem to be unique in Thai epigraphy. Two of these carry extracts from the Abhidhamma; the third gives a syllabary followed by the recollection formulas of the Three Gems. The other two epigraphs are written not on stone slabs but are inscribed on small gold leaves; they contain the (...) heart formulas of the books of the Tipi?aka and the qualities of the Buddha, Dhamma, and Sa?gha. The exact find-spots and functions of the slabs and gold leaves are not known. I suggest that they are the products of widespread and enduring Buddhist cultures of inscription, installation, and consecration, as well as of customs of condensation and abbreviation that have have been intrinsic to Thai liturgical and manuscript practices up to the present.

It is now widely accepted that microorganisms play many important roles in the lives of plants and animals. Every macroorganism has been shaped in some way by microorganisms. The recognition of the ubiquity and importance of microorganisms has led some to argue for a revolution in how we understand biological individuality and the primary units of natural selection. The term “holobiont” was introduced as a name for the biological unit made up by a host and all of its associated microorganisms, (...) and much of this new debate about biological individuality has focused on whether holobionts are integrated individuals or communities. In this paper, I show how parts of the holobiont can span both characterizations. I argue that most holobionts share more affinities with communities than they do with organisms, and that, except for maybe in rare cases, holobionts do not meet the criteria for being organisms, evolutionary individuals, or units of selection.

Gordon Skilling writes candidly of each way station in this personal odyssey: the idealism of his student years at the University of Toronto and Oxford; his presence in Czechoslovakia on the eve of the Nazi, and later Soviet, invasions; his opposition to the Marshall Plan, NATO, and U.S. intervention in Korea; the effect of McCarthyism on his academic life; his involvement with the Czech and Slovak dissident movements and finally the Velvet Revolution. The Education of a Canadian also captures conversations (...) with writers, journalists, scholars, and myriad friends throughout Russia and Eastern Europe, making this history a distinctly human yet forceful document of profound humanity and international scope.

Comparing preferences for sport participation between alternative and conventional sports, this article exhibits some differences across sport contexts, as well as across gender and class. However, the main finding is the major similarities of preferences and dominating social groups across the contexts. This indicates that a similar habitus is in play in the alternative context as in the conventional one, and that "real alternatives" are merely to occur inside established frames of sport provision.

Summary This paper reports on the perspectives of elite athletes on anti-doping work in general and on the whereabouts system in particular, and uses a figurational perspective to explore the unintended consequences of the planned introduction of the whereabouts system. A cross-sectional survey of all the athletes in the Norwegian registered testing pool was carried out in 2006, using a structured questionnaire. Overall, 70.6% of the athletes agreed that doping was a problem in elite sport in general, but paradoxically only (...) 17.5% agreed that doping was a problem in their own sport. However, more than four in ten of the athletes agreed that the whereabouts information system made a contribution to a “cleaner” sport. Some athletes thought the system was unfair. The whereabouts information system had, despite all good intentions, outcomes other than those planned and intended by the WADA. Thus, athletes’ views might fruitfully be integrated with other perspectives when anti-doping work is developed further. (shrink)

Theoretical accounts of development exhibit several internal tensions and face multiple challenges. They span from the problem of the identification of the temporal boundaries of development (beginning and end) to the characterization of the distinctive type of change involved compared to other biological processes. They include questions such as the role to ascribe to the environment or what types of biological systems can undergo development and whether they should include colonies or even ecosystems. In this chapter we discuss these conceptual (...) issues, and we argue that adopting an organizational approach may help solve or clarify them. -/- While development is usually identified with the achievement of an adult form with the capability to reproduce and therefore maintain a lineage, adopting the organizational approach may provide a different strategy, which focuses also on the maintenance of the current organization of the organism. By doing so an organizational approach favors a switch in perspective which consists in analyzing how organisms maintain their viability at each moment of development rather than considering them as going through intermediate stages of a process directed toward a specific goal state. This developmental dimension of biological organization has yet to be given a general and detailed analysis within the organizational theoretical perspective, apart from some preliminary attempts. How a biological organization is maintained through a series of radical organizational changes and what these changes are issues that still require clarification. In this chapter we offer the beginnings of such an analysis of developmental transitions, understood as changes in functionality brought forth by regulatory mechanisms in the context of the continued maintenance of organizational viability at every step.

Academic health centres have historically treated patients with the most complex of diseases, served as training grounds to teach the next generations of physicians and fostered an innovative environment for research and discovery. The physicians who hold faculty positions at these institutions have long understood how these key academic goals are critical to serve their patient community effectively. Recent healthcare reforms, however, have led many academic health centres to recruit physicians without these same academic expectations and to partner with non-faculty (...) physicians at other health systems. There has been limited transparency in regard to the expertise among the physicians and the academic faculty within these larger entities. Such lack of transparency may lead to confusion among patients regarding the qualifications of who is actually treating them. This could threaten the ethical principles of patient autonomy, benevolence and non-maleficence as patients risk making uninformed decisions that might lead to poorer outcomes. Furthermore, this lack of transparency unjustly devalues the achievements of physician faculty members as well as potentially the university they represent. In this paper, it is suggested that academic health centres have an obligation to foster total transparency regarding what if any role a physician has at a university or medical school when university or other academic monikers are used at a hospital.

The Udanavarga is a grand compendium of Buddhist verse, compiled by a Dharmatrata about whom we know next to nothing. In Sarvastivadin and Mulasarvastivadin circles the Udanavarga was as popular as is the Dhammapada in Theravadin circles, and it circulated widely in South and Central Asia. Here I give an English translation from the Tibetan of the first chapter, ‘Impermanence’.

The theoretical construction and practical use of prior probabilities, in particular for systems having many degrees of freedom, are investigated. It becomes clear that it is operationally unsound to use mutually consistent priors if one wishes to draw sensible conclusions from practical experiments. The prior cannot usefully be identified with a state of knowledge, and indeed it is not so identified in common scientific practice. Rather, it can be identified with the question one asks. Accordingly, priors are free constructions. Their (...) informal, ill-defined and subjective characteristics must carry over into the conclusions one chooses to draw from experiments or observations.

. Early microbiome research found numerous associations between microbial community patterns and host physiological states. These findings hinted at community-level explanations. “Top-down” experiments, working with whole communities, strengthened these explanatory expectations. Now, “bottom-up” mechanism-seeking approaches are dissecting communities to focus on specific microbes carrying out particular biochemical activities. To understand the interplay between methodological and explanatory scales, we examine claims of “dysbiosis,” when host illness is proposed as the consequence of a community state. Our analysis concludes with general observations about (...) how methodologies relate to explanations, and the implications for microbiome research. (shrink)

Much contemporary social epistemology takes as its starting point individuals with sophisticated propositional attitudes and considers (i) how those individuals depend on each other to gain (or lose) knowledge through testimony, disagreement, and the like and (ii) if, in addition to individual knowers, it is possible for groups to have knowledge. In this paper I argue that social epistemology should be more attentive to the construction of knowers through social and cultural practices: socialization shapes our psychological and practical orientation so (...) that we perform local social practices fluently. Connecting practical orientation to an account of ideology, I argue that to ignore the ways in which cognition is socially shaped and filtered is to allow ideology to do its work unnoticed and unimpeded. Moreover, ideology critique cannot simply challenge belief, but must involve challenges to those practices through which we ourselves become the vehicles and embodiments of ideology.V. (shrink)

Philosophical questions surrounding skill and expertise can be traced back as far as Ancient Greece, China, and India. In the twentieth century skilled action was an important factor in the work of phenomenologists such as Heidegger and Merleau-Ponty and analytic philosophers including Gilbert Ryle. However, as a subject in its own right it has, until now, remained largely in the background. The Routledge Handbook of Philosophy of Skill and Expertise is an outstanding reference source and the first major (...) collection of its kind, reflecting the explosion of interest in the topic recent years. Comprising thirty-nine chapters written by leading international contributors, the Handbook is organised into six clear parts: Skill in the History of Philosophy Skill in Epistemology Skill, intelligence, and agency Skill in Perception, Imagination, and Emotion Skill, Language, and, Social Cognition Skill and Expertise in Normative Philosophy. Essential reading for students and researchers in philosophy of mind and psychology, epistemology and ethics, The Routledge Handbook of Philosophy of Skill and Expertise is also suitable for those in related disciplines such as social psychology and cognitive science. It is also relevant to those who are interested in conceptual issues underlying skill and expertise in fields such as sport, the performing arts, and medicine. (shrink)

In this work Tim Ingold provides a persuasive new approach to the theory behind our perception of the world around us. The core of the argument is that where we refer to cultural variation we should be instead be talking about variation in skill. Neither genetically innate or culturally acquired, skills are incorporated into the human organism through practice and training in an environment.They are as much biological as cultural.

We address the thesis recently proposed by Andy Clark, that skill-mediated access to modality implies phenomenal feel. We agree that a skill theory of perception does indeed offer the possibility of a satisfactory account of the feel of perception, but we claim that this is not only through explanation of access to modality but also because skill actually provides access to perceptual property in general. We illustrate and substantiate our claims by reference to the recently proposed 'sensorimotor (...) contingency' theory of visual awareness. We discuss why this theory offers a distinctively attractive access-based approach to perceptual consciousness because it 'dereifies' experience and permits otherwise problematic aspects of phenomenal perceptual consciousness to be explained. We suggest our approach thus offers the prospect of 'naturalizing phenomenology'. (shrink)

Skilful expertise is grounded in practical, performative knowledge-how, not in detached, spectatorial knowledge-that, and knowledge-how is embodied by habitual dispositions, not representation of facts and rules. Consequently, as action control is a key requirement for the intelligent selection, initiation, and regulation of skilful performance, habitual action control, i.e. the kind of action control based on habitual dispositions, is the true hallmark of skill and the only veridical criterion to evaluate expertise. Not only does this imply that knowledge-that does not (...) make your actions more skilful, but it also implies that it makes them less skilful. This thesis, that I call Radical Habitualism, finds a precursor in Hubert Dreyfus. His approach is considered extreme by most philosophers of skill & expertise: an agent –says Dreyfus– does not perform like an expert when they lack the embodied dispositions necessary to control their action habitually or when they stop relying on such dispositions to control their actions. Thus, one cannot perform skilfully if their actions are guided by representations (isomorphic schemas, explicit rules, and contentful instructions), as the know-that that they convey disrupts or diminishes the agent’s habitual engagement with the task at hand. In defence of Radical Habitualism, I will argue that only the contentless know-how embedded in habitual dispositions fulfils (i) the genetic, (ii) the normative, and (iii) the epistemic requirements of skilful performance. I will examine the phenomenological premises supporting Dreyfus’ approach, clarify their significance for a satisfactory normative and explanatory account of skilful expertise, and rebut the most common objections raised by both intellectualists and conciliatory habitualists, concerning hybrid actions guided by a mix of habitual and representational forms of control. In revisiting Dreyfus anti-representationalist approach, I will particularly focus on its epistemological implications, de-emphasizing other considerations related to conscious awareness. (shrink)

The objective of this paper is to characterize the rich interplay between automatic and cognitive control processes that we propose is the hallmark of skill, in contrast to habit, and what accounts for its flexibility. We argue that this interplay isn't entirely hierarchical and static, but rather heterarchical and dynamic. We further argue that it crucially depends on the acquisition of detailed and well-structured action representations and internal models, as well as the concomitant development of metacontrol processes that can (...) be used to shape and balance it.

How does skill relate to dào 道, the ethically apt path and its performance? Two early Chinese ‘masters’ anthologies that make prominent use of craft metaphors imply profoundly contrasting answers to this question. For the Mòzǐ 墨子, a key to following dào is to set forth explicit models or standards for guiding and checking performance. By learning to consistently apply the right standards, we can develop the skill needed to follow the dào of the sage-kings reliably, just as (...) a carpenter uses a set square to produce square corners or a wheelwright uses a wing compass to fashion round wheels. Following dào—and thus the ethical life—is strongly analogous to the performance of skills. Like an artisan’s craft, dào has a fixed end that can be explicitly articulated. A sharply contrasting stance is implied by the renowned skill exemplar Páo Dīng the butcher in the Zhuāngzǐ 莊子. Praised for how his every movement in carving up cattle is perfectly attuned, yielding a display of skill matching that of an exquisite dance or musical performance, the butcher responds that what he actually cares about is dào, which is ‘advanced beyond skill’. Intriguingly, most of what Páo Dīng says in explaining this point pertains to how he developed his craft, performs his work, and overcomes new challenges. The implication is that the process of acquiring, performing, and extending skills exemplifies dào, yet there is something more to dào than skill. What is this something more? A skill is the ability to competently perform a task with a specified end. In the Zhuāngzǐ, a key difference between skill and dào, I will suggest, is that dào is unlike skill in having no fixed, predetermined ends. Dào is a general, open-ended process, one that is continually shifting and transforming. We can never fully master dào, nor even know exactly where it will lead, as the nature of dào is such that we must regularly find creative ways of extending it as we proceed along it. (shrink)

I draw on empirical results from perceptual and motor learning to argue for an anti-intellectualist position on skill. Anti-intellectualists claim that skill or know-how is non-propositional. Recent proponents of the view have stressed the flexible but fine-grained nature of skilled control as supporting their position. However, they have left the nature of the mental representations underlying such control undertheorized. This leaves open several possible strategies for the intellectualist, particularly with regard to skill learning. Propositional knowledge may structure (...) the inputs to sensorimotor learning, may constitute the outcomes of said learning, or may be needed for the employment of learned skill. I argue that sensorimotor learning produces multi-scale associational representations, and that these representations are of the right sort to underlie flexible and fine-grained control. I then suggest that their content is vitally indeterminate with regard to propositional content attribution, because they exhibit a kind of open-ended structure. I articulate this kind of structure, and use it to respond to the three intellectualist strategies. I then show how the perspective I advance offers insights for understanding both instruction and expert practice. (shrink)

Theorists have hypothesized that skill in critical thinking is positively correlated with the consistent internal motivation to think and that specific critical thinking skills are matched with specific critical thinking dispositions. If true, these assumptions suggest that a skill-focused curriculum would lead persons to be both willing and able to think. This essay presents a researchbased expert consensus definition of critical thinking, argues that human dispositions are neither hidden nor unknowable, describes a scientific process of developing conventional testing (...) tools to measure cognitive skills and human dispositions, and summarizes recent empirical research findings that explore the possible relationship of critical thinking skill and the consistent internal motivation, or disposition, to use that skill. Empirical studies indicate that for all practical purposes the hypothesized correlations are not evident. It would appear that effective teaching must include strategies for building intellectual character rather than relying exclusively on strengthening cognitive skills. (shrink)

The aim of this commentary is to complement Haslanger’s view of cognition as a skill shaped by culture. I start by presenting an empirically oriented account of the process of enculturation based on the cognitive integration framework. I then illustrate the active role of material (and not just symbolic) culture in cognition by drawing on extended cognition theory. Finally, I argue that embedding Haslanger’s work within these two theories of cognition better serves the objectives of her project and, at (...) the same time, promotes a critical philosophy of cognitive science.

One prominent intellectualist position in the debate on the nature of skill, famously defended by Stanley and Williamson (2001; 2017), claims that skill and knowing-how are reducible to knowledgethat. To defend this claim, Stanley and Williamson argue that skill and knowledge-that develop in a sufficiently similar way through different learning stages. In this paper we offer a novel argument to reject this version of intellectualism on methodological, descriptive, and conceptual grounds. We do so by drawing on the (...) work of Heidegger, Dreyfus, and Ryle on skill. We first offer a descriptive account of skilful action based on the work developed by these authors, and we then move on to show that skill and knowledge-that exhibit significant differences. First, while skills cannot be imparted merely linguistically, some forms of knowledge-that can be exclusively imparted and learned verbally. Second, weshow that the temporal learning curves of skill and knowledge-that are importantly different: the former usually requires a more or less extensive training process, whereas the latter may be acquired in a relatively sudden fashion. Finally, we show that, while the structure of most forms of knowledge-that is aggregative, the structure of skilful understanding is dynamic and holistic, which entails that prior skill stages cannot be retrieved and re-enacted at will.
