This book presents the framework for a new, comprehensive approach to cognitive science. The proposed paradigm, enaction, offers an alternative to cognitive science's classical, first-generation Computational Theory of Mind. _Enaction_, first articulated by Varela, Thompson, and Rosch in _The Embodied Mind_, breaks from CTM's formalisms of information processing and symbolic representations to view cognition as grounded in the sensorimotor dynamics of the interactions between a living organism and its environment. A living organism enacts the world it lives in; its embodied (...) action in the world constitutes its perception and thereby grounds its cognition. _Enaction_ offers a range of perspectives on this exciting new approach to embodied cognitive science. Some chapters offer manifestos for the enaction paradigm; others address specific areas of research, including artificial intelligence, developmental psychology, neuroscience, language, phenomenology, and culture and cognition. Three themes emerge as testimony to the originality and specificity of enaction as a paradigm: the relation between first-person lived experience and third-person natural science; the ambition to provide an encompassing framework applicable at levels from the cell to society; and the difficulties of reflexivity. Taken together, the chapters offer nothing less than the framework for a far-reaching renewal of cognitive science.

The term “social cognition” can be construed in different ways. On the one hand, it can refer to the cognitive faculties involved in social activities, defined simply as situations where two or more individuals interact. On this view, social systems would consist of interactions between autonomous individuals; these interactions form higher-level autonomous domains not reducible to individual actions. A contrasting, alternative view is based on a much stronger theoretical definition of a truly social domain, which is always defined by a (...) set of structural norms; moreover, these social structures are not only a set of constraints, but actually constitute the possibility of enacting worlds that would just not exist without them. This view emphasises the heteronomy of individuals who abide by norms that are impersonal, culturally inherited and to a large extent independent of the individuals. Human beings are socialised through and through; consequently, all human cognition is social cognition. The article argues for this second position. Finally, it appears that fully blown autonomy actually requires heteronomy. It is the acceptance of the constraints of social structures that enables individuals to enter new realms of common meaningfulness. The emergence of social life marks a crucial step in the evolution of cognition; so that at some evolutionary point human cognition cannot but be social cognition. (shrink)

The evolution of life on Earth has produced an organism that is beginning to model and understand its own evolution and the possible future evolution of life in the universe. These models and associated evidence show that evolution on Earth has a trajectory. The scale over which living processes are organized cooperatively has increased progressively, as has its evolvability. Recent theoretical advances raise the possibility that this trajectory is itself part of a wider developmental process. According to these theories, the (...) developmental process has been shaped by a yet larger evolutionary dynamic that involves the reproduction of universes. This evolutionary dynamic has tuned the key parameters of the universe to increase the likelihood that life will emerge and produce outcomes that are successful in the larger process (e.g. a key outcome may be to produce life and intelligence that intentionally reproduces the universe and tunes the parameters of ‘offspring’ universes). Theory suggests that when life emerges on a planet, it moves along this trajectory of its own accord. However, at a particular point evolution will continue to advance only if organisms emerge that decide to advance the developmental process intentionally. The organisms must be prepared to make this commitment even though the ultimate nature and destination of the process is uncertain, and may forever remain unknown. Organisms that complete this transition to intentional evolution will drive the further development of life and intelligence in the universe. Humanity’s increasing understanding of the evolution of life in the universe is rapidly bringing it to the threshold of this major evolutionary transition. (shrink)

"The picture of Hume clinging timidly to a raft of custom and artifice, because, poor skeptic, he has no alternative, is wrong," writes John Stewart. "Hume was confident that by experience and reflection philosophers can achieve true principles." In this revisionary work Stewart surveys all of David Hume's major writings to reveal him as a liberal moral and political philosopher. Against the background of seventeenth-and eighteenth-century history and thought, Hume emerges as a proponent not of conservatism but of reform. Stewart (...) first presents the dilemma over morals in the modern natural-law school, then examines the new approach to moral and political philosophy adopted by Hume's precursors Shaftesbury, Mandeville, Hutcheson, and Butler. Illuminating Hume's explanation of the standards and rules that should govern private and public life, the author challenges interpretations of Hume's philosophy as conservative by demonstrating that he did not dismiss reason as a key factor determining right and wrong in moral and political contexts. Stewart goes on to show that Hume viewed private property, the market, contracts, and the rule of law as essential to genuine civilized society, and explores Hume's criticism of contemporary British beliefs concerning government, religion, commerce, international relations, and social structure.

Classically, the question of recognizing another subject is posed unilaterally, in terms of the observed behaviour of the other entity. Here, we propose an alternative, based on the emergent patterns of activity resulting from the interaction of both partners. We employ a minimalist device which forces the subjects to externalize their perceptual activity as trajectories which can be observed and recorded; the results show that subjects do identify the situation of perceptual crossing with their partner. The interpretation of the results (...) is guided by comparable evolutionary robotics simulations. There are two components to subjects’ recognition capacities: distinguishing mobile and fixed entities; and behaving so as to interact with their partner rather than with a mobile lure. The “Other” is characterized by the feature that there is sufficient regularity in the interactions to encourage the formation of anticipations; but sufficient indetermination that the actual behaviour is consistently surprising.

"The book provides an excellent historical summary of the debates over continental drift theory in this century." —Contemporary Sociology "This is a useful discussion of the way that science works. The book will be of value to philosophers of science... " —Choice "... will find an important place in university and department libraries, and will interest afficionados of the factual and intellectual history of the earth sciences." —Terra Nova "... an excellent core analysis... " —The Times Higher Education Supplement "... (...) an ambitious and important contribution to the new sociology of science." —American Journal of Sociology "... Stewart's book is a noble effort, an interesting and readable discussion, and another higher notch on the scoreboard of critical scholarship that deserves wide examination and close attention." —Geophysics This fascinating book describes the rise and fall and rebirth of continental drift theory in this century. It uses the recent revolution in geoscientinsts' beliefs about the earth to examine questions such as, How does scientific knowledge develop and change? The book also explores how well different perspectives help us to understand revolutionary change in science. (shrink)

Mi Gyung Kim (2008) has challenged the historiographical assumption that phlogiston was the paradigmatic concept in eighteenth century chemistry. Her analysis of the operational, theoretical, and philosophical identities of phlogiston demonstrates how Stahlian phlogiston was appropriated into the burgeoning field of affinity theory. However, this new French conception of phlogiston was destabilized by the introduction of Boerhaave's thermometrics. By extending this story through 1790, I will show that British pneumatic chemists integrated new understandings of heat with an affinity based operational (...) definition of phlogiston and thereby stabilized the concept. What resulted was a new and very different phlogiston. (shrink)

Vidal’s (Found Sci, 2010 ) and Rottiers’s (Found Sci, 2010 ) commentaries on my (2010) paper raised a number of important issues about the possible future trajectory of evolution and its implications for humanity. My response emphasizes that despite the inherent uncertainty involved in extrapolating the trajectory of evolution into the far future, the possibilities it reveals nonetheless have significant strategic implications for what we do with our lives here and now, individually and collectively. One important implication is the replacement (...) of postmodern scepticism and relativism with an evolutionary grand narrative that can guide humanity to participate successfully in the future evolution of life in the universe.

The ‘managed-metabolism’ hypothesis suggests that a ‘cooperation barrier’ must be overcome if self-producing chemical organizations are to undergo the transition from non-life to life. This dynamical barrier prevents un-managed autocatalytic networks of molecular species from individuating into complex, cooperative organizations. The barrier arises because molecular species that could otherwise make significant cooperative contributions to the success of an organization will often not be supported within the organization, and because side reactions and other ‘free-riding’ processes will undermine cooperation. As a result, (...) the barrier seriously impedes the emergence of individuality, complex functionality and the transition to life. This barrier is analogous to the cooperation barrier that also impedes the emergence of complex cooperation at all levels of living organization. As has been shown at other levels of organization, the barrier can be overcome comprehensively by appropriate ‘management’. Management implements a system of evolvable constraints that can overcome the cooperation barrier by ensuring that beneficial co-operators are supported within the organization and by suppressing free-riders. In this way, management can control and manipulate the chemical processes of a collectively autocatalytic organization, producing novel processes that serve the interests of the organization as a whole and that could not arise and persist in an un-managed chemical organization. Management self-organizes because it is able to capture some of the benefits that are produced when its interventions promote cooperation, thereby enhancing productivity. Selection will therefore favour the emergence of managers that take over and manage chemical organizations so as to overcome the cooperation barrier. The managed-metabolism hypothesis demonstrates that if management is to overcome the cooperation barrier comprehensively, its interventions must be digitally coded. In this way, the hypothesis accounts for the two-tiered structure of all living cells in which a digitally-coded genetic apparatus manages an analogically-informed metabolism. Graphical Abstract.

What is the potential for improvements in the functioning of consciousness? The paper addresses this issue using global workspace theory. According to this model, the prime function of consciousness is to develop novel adaptive responses. Consciousness does this by putting together new combinations of knowledge, skills and other disparate resources that are recruited from throughout the brain. The paper's search for potential improvements in consciousness is aided by studies of a developmental transition that enhances functioning in whichever domain it occurs. (...) This transition involves a shift from the use of procedural (implicit) knowledge to declarative (explicit) knowledge. However, the potential of the transition to enhance functioning has not yet been realised to any extent in relation to consciousness itself. The paper assesses the potential for consciousness to use declarative knowledge to improve its own functioning and to thereby enhance human adaptability. A number of sources (including the practices of religious and contemplative traditions) are drawn on to investigate how this potential might be realised. (shrink)

In his Target Article, Terrence Deacon develops simple models that assist in understanding the role of RNA in the origins of life. However, his models fail to adequately represent an important evolutionary dynamic. Central to this dynamic is the selection that impinges on RNA molecules in the context of their association with proto-metabolisms. This selection shapes the role of RNA in the emergence of life. When this evolutionary dynamic is appropriately taken into account, it predicts a role for RNA that (...) is consistent with the Managed-Metabolism Hypothesis about the origins of life, and inconsistent with Deacon’s account.

The strategies of action employed by a human subject in order to perceive simple 2-D forms on the basis of tactile sensory feedback have been modelled by an explicit computer algorithm. The modelling process has been constrained and informed by the capacity of human subjects both to consciously describe their own strategies, and to apply explicit strategies; thus, the strategies effectively employed by the human subject have been influenced by the modelling process itself. On this basis, good qualitative and semi-quantitative (...) agreement has been achieved between the trajectories produced by a human subject, and the traces produced by a computer algorithm. The advantage of this reciprocal modelling option, besides facilitating agreement between the algorithm and the empirically observed trajectories, is that the theoretical model provides an explanation, and not just a description, of the active perception of the human subject.

Humans are able to construct mental representations and models of possible interactions with their environment. They can use these mental models to identify actions that will enable them to achieve their adaptive goals. But humans do not use this capacity to identify and implement the actions that would contribute most to the evolutionary success of humanity. In general, humans do not find motivation or satisfaction in doing so, no matter how effective such actions might be in evolutionary terms. From an (...) evolutionary perspective, this is a significant limitation in the psychological adaptability of humans. This paper sets out to identify the new psychological capacity that would be needed to overcome this limitation and how the new capacity might be acquired. Humans that develop this capacity will become self-evolving organisms - organisms that are able to adapt in whatever ways are necessary for future evolutionary success, largely unfettered by their biological and social past.

This article addresses the issue of objectivism vs constructivism in two areas,biology and cognitive science, which areintermediate between the natural sciences suchas physics (where objectivism is dominant) andthe human and social sciences (whereconstructivism is widespread). The issues inbiology and in cognitive science are intimatelyrelated; in each of these twin areas, the objectivism vs constructivism issue isinterestingly and rather evenly balanced; as aresult, this issue engenders two contrastingparadigms, each of which has substantialspecific scientific content. The neo-Darwinianparadigm in biology is closely resonant (...) withthe classical cognitivist paradigm in cognitivescience, and both of them are intrinsicallyobjectivist. The organismic paradigm inbiology, based on the concept of autopoiesis,is consonant with the paradigm of enaction incognitive science; the latter paradigms are bothprofoundly constructivist.In cognitive science, the objectivism vsconstructivism issue is internal to thescientific field itself and reflexivity isinescapable. At this level, strong ontologicalobjectivism is self-contradictory and thereforeuntenable. Radical constructivism isself-coherent; but it also rehabilitatesa weak form of objectivism as a pragmaticallyviable alternative. In conclusion, there is aneven-handed reciprocity between objectivistand constructivist perspectives. Finally, thearticle examines the consequences of thisconclusion for fields other than cognitivescience: biology; physics and the naturalsciences; and the human and social sciences. (shrink)

This article examines the British child guidance movement's claim to scientific status and what it sought to gain by the wider acceptance of such a claim. The period covered is from the movement's origins in the 1920s to the end of the Second World War, by which point it had been incorporated into the welfare state. This was also an era when science commanded high intellectual and cultural status. Child guidance was a form of psychiatric medicine that addressed the emotional (...) and psychological difficulties that any child might experience. It thus saw itself as a form of preventive medicine and as a component of the international movement for mental hygiene. Child guidance was organized around the clinic and employed the knowledge and skills of three distinct professions: psychiatrists, psychologists and psychiatric social workers. Its claim to scientific status was underpinned by the movement's clinical and organizational approach and in turn derived from developments in the laboratory sciences and in academic medicine. There were, however, those even within the movement itself who challenged child guidance's purported scientific status. Such objections notwithstanding, it is suggested here that at least in its own terms the claim was justified, particularly because of the type of psychiatric approach which child guidance employed, based as it was on a form of medical holism.

Does the Big History of life on Earth disclose a trajectory that has been driven by selection? If so, will the trajectory continue to apply into the future? This paper argues that such a trajectory exists, and examines some of its key implications. The most important consequence is that humanity can use the trajectory to guide how it evolves and adapts into the future. This is because the trajectory identifies a sequence of adaptations that will be favoured by selection. If (...) humanity intentionally evolves its social systems and psychological capacities so that they follow the trajectory, humanity can avoid negative selection and instead survive and thrive indefinitely into the future. This would enable humanity to make a positive contribution to the future evolution of life in the universe. But it turns out that immediate selection will not drive the evolution of life on Earth further along this trajectory. Instead, intentional action by humanity is necessary. It is as if the evolution of life on any planet is a developmental process that has a very unusual characteristic: evolution will continue to develop successfully beyond a certain point only if it produces a sentient organism that: (i) awakens to the possibility it is embedded in a developing process; (ii) realizes that this developing process will continue successfully only if it chooses to intentionally drive the process forward; and (iii) commits to doing whatever is necessary to achieve this. On this planet, humanity is that sentient organism. The existence of such a key evolutionary role for humanity is capable of providing humanity with meaning and purpose in a larger scheme of things. For individuals who commit to driving the process forward, the nature of the trajectory has immediate consequences for what they should do with their lives, here and now. (shrink)

Open peer commentary on the article “Excavating Belief About Past Experience: Experiential Dynamics of the Reflective Act” by Urban Kordeš & Ema Demšar. Upshot: The theme of lived experience involves an intensely personal, subjective, existential dimension; if this is not taken up, something essential is missing.

Setting up a dialectic between knowing and being poses an uncomfortable challenge to our usual way of doing science. As a modest contribution to the new collective culture we need, this commentary shares a few Zen koans, and three Taoist stories.

The commentator’s motivation for accompanying Varela in a foray into immunology lay in the clear-cut, value-laden contrast between traditional immunology and the new organism-centred view pioneered by Vaz and Coutinho. In the twenty years that have elapsed, models have become increasingly complicated so that this clear-cut contrast has been obscured. In immunology as in cognitive science, the radicality of Varela’s views is disturbing for the mainstream community.

Des Anglophones peuvent éprouver quelques difficultés à comprendre la différence entre « langue » et « langage », car en anglais il existe un seul mot pour les deux, à savoir « language ». L’œuvre de Pierre-Yves Raccah est caractérisé par une très grande précision et rigueur ; cela est bien illustré par la terminologie qu’il a établi selon laquelle le terme « langue » correspond à une langue naturelle comme le Français ou l’Anglais ; alors que le terme « (...) langage » renvoie à un langage formel, le langage de la logique. Les énoncés dans une langue naturelle sont généralement des « phrases », ce qui signifie que leur interprétation appelle toujours une négociation et dépend fortement de la situation contextuelle. Par contre, les énoncés dans un langage formel prennent la forme de propositions logiques, qui possèdent apparemment une seule interprétation – quoique, il convient de le préciser, cette apparence dépend en réalité d’un contexte bien particulier, celui qui est établi par la communauté des logiciens. Raccah a déployé cette distinction importante dans un article qui constitue le point focal de cette contribution. Raccah y présente un argument bien structuré, qui le conduit à conclure que « la métaphore n’existe pas ». La raison est que dans les langues naturelles, tous les mots sont normalement des métaphores ; il s’ensuit que « la métaphore », comme trope particulier qui appelle une explication, n’existe effectivement pas. Dans ma contribution, je propose de présenter une approche complémentaire, prenant comme cadre le paradigme de l’Énaction en Sciences Cognitives, qui conduit à une conclusion sensiblement identique. Finalement, je propose de formuler une nouvelle question qui se pose si l’on considère que « la métaphore » est normale ; il s’agit du statut des « énoncés littéraux » qui, par une ironie du sort suite au renversement de la situation, deviennent à leur tour problématiques.

The dominant current in the contemporary environmental movement fails to make the connection between the preservation of the environment and the survival of humans. The fashionable concept of the “Anthropocene” is not fully adequate to get to grips with the full gravity of the situation. Contemporary human society, based on a neo-liberal market economy, is “locked in” to a productivist mode of existence, so that it will be extremely difficult to abandon the goal of “growth” and to achieve a sustainable (...) relationship with the eco-system on which human existence depends. The “TAC” thesis, that “Technology is Anthropologically Constitutive,” has a dark side: technology may be anthropologically destructive. (shrink)

ABSTRACTThe Scottish Enlightenment has long been identified with abolitionism because of the writings of the moral and economic philosophers and the absence of slaves in Scotland itself. However, Scots were disproportionately represented in the ownership, management, and especially medical treatment of slaves in the British Caribbean. Sugar and cotton flowed into Glasgow and young, educated Scots looking for work as traders, bookkeepers, doctors made the return trip back to the Caribbean to manage the plantations. Chemically trained doctors and agriculturalists tested (...) their theories in the plantations and developed new theories based on their experimentation on the land and slaves. In foregrounding the participation of Scottish trained chemists in the practice of slavery, I argue that the development of eighteenth-century chemistry and the broader intellectual Enlightenment were inextricably entangled with the economic Improvement Movement and the colonial economy of the British slave trade.

The schematic concept of levels of causal interaction is applied to the relation between genetics and biology. The strength of classical formal genetics lies in its power to proceed directly from observations on an external phenotype, to inferences concerning the nature and properties of the fundamental genetic factors. Its weakness comes from the fact that by short-circuiting the causal chain leading from genotype to phenotype, it creates a divorce between genetics and biology. It is argued that in order to reestablish (...) an articulation of genetics and the biology of whole organisms, it will be necessary to study in detail the entire causal chain leading from a difference in a genetic factor to a difference in a corresponding phenotypic character. This proposal is illustrated by a consideration of multifactorial diseases, which appear to be due to strong interactions between a moderate number of distinct loci; the frequency of abnormal alleles at any given locus may be surprisingly high.

The first edition of Thomas Robert Malthus’ Essay on the Principle of Population is best understood as an exploration of human nature and the role of necessity in shaping the individual and society. The author’s liberal education, both from his father and his tutors at Warrington and Cambridge, is evident in his heterodox views on hell, his Lockean conceptualization of the mind, and his Foxite Whig politics. Malthus’ unpublished essay, “Crises,” his sermons, and the the last two chapters of the (...) Essay reveal a pragmatic, compassionate side of the young author that was under appreciated by both his contemporary critics and modern historians. The Essay has been mischaracterized by David McNally as a “Whig response to Radicalism” and by Patricia James as a reaction by Malthus against his father’s liberalism. This article argues that when he wrote the first edition of the Essay on the Principle of Population, Malthus was himself a liberal dissenter and Foxite Whig rather than an orthodox Anglican or a Burkean defender of traditional class relations.
