This introduction to a special issue of Topoi introduces and summarises the relationship between three main varieties of 'enactivist' theorising about the mind: 'autopoietic', 'sensorimotor', and 'radical' enactivism. It includes a brief discussion of the philosophical and cognitive scientific precursors to enactivist theories, and the relationship of enactivism to other trends in embodied cognitive science and philosophy of mind.

In this paper we will demonstrate that a computational system can meet the criteria for autonomy laid down by classical enactivism. The two criteria that we will focus on are operational closure and structural determinism, and we will show that both can be applied to a basic example of a physically instantiated Turing machine. We will also address the question of precariousness, and briefly suggest that a precarious Turing machine could be designed. Our aim in this paper is to challenge (...) the assumption that computational systems are necessarily heteronomous systems, to try and motivate in enactivism a more nuanced and less rigid conception of computational systems, and to demonstrate to computational theorists that they might find some interesting material within the enactivist tradition, despite its historical hostility towards computationalism.

Building on the original formulation of the autopoietic theory (AT), extended enactivism argues that living beings are autopoietic systems that extend beyond the spatial boundaries of the organism. In this article, we argue that extended enactivism, despite having some basis in AT’s original formulation, mistakes AT’s definition of living beings as autopoietic entities. We offer, as a reply to this interpretation, a more embodied reformulation of autopoiesis, which we think is necessary to counterbalance the (excessively) disembodied spirit of AT’s original (...) formulation. The article aims to clarify and correct what we take to be a misinterpretation of AT as a research program. AT, contrary to what some enactivists seem to believe, did not (and does not) intend to motivate an extended conception of living beings. AT’s primary purpose, we argue, was (and is) to provide a universal individuation criterion for living beings, these understood as discrete bodies that are embedded in, but not constituted by, the environment that surrounds them. However, by giving a more explicitly embodied definition of living beings, AT can rectify and accommodate, so we argue, the enactive extended interpretation of autopoiesis, showing that although living beings do not extend beyond their boundaries as autopoietic unities, they do form part, in normal conditions, of broader autopoietic systems that include the environment.

The autopoietic theory and the enactive approach are two theoretical streams that, in spite of their historical link and conceptual affinities, offer very different views on the nature of living beings. In this paper, we compare these views and evaluate, in an exploratory way, their respective degrees of internal coherence. Focusing the analyses on certain key notions such as autonomy and organizational closure, we argue that while the autopoietic theory manages to elaborate an internally consistent conception of living beings, the (...) enactive approach presents an internal tension regarding its characterization of living beings as intentional systems directed at the environment.

This paper suggests that the enactive approach to ethics could benefit from engaging a dialogue with the phenomenology of Emmanuel Levinas, a philosopher who has given ethics a decisive role in the understanding of our social life. Taking the enactive approach of Colombetti and Torrance as a starting point, we show how Levinas’ philosophy, with the key notions of face, otherness, and responsibility among others can complement and enrich the enactive view of ethics. Specifically, we argue that Levinas can provide, (...) on the one hand, a phenomenological characterisation of ethics itself, of its nature and fundamental meaning, and on the other, an account of how sociality, affectivity and embodiment, as presented in Colombetti and Torrance’s work, combine to bring about the ethical experience. However, we also point out that introducing Levinas to the enactive approach could be challenging. It is not obvious how sense-making and value-making, as centred on the precariousness and potential death of the subject, would account for the ethical experience as grounded on the precariousness and potential death of the other.

This paper examines a fundamental philosophical difference between two radical postcognitivist theories that are usually assumed to offer the same view of cognition; namely the autopoietic theory and the enactive approach. The ways these two theories understand cognition, it is argued, are not compatible nor incompatible but rather incommensurable. The reason, so it is argued, is that while enactivism, following the traditional stance held by most of the cognitive theories, understands cognitive systems as constituting a natural kind, the autopoietic theory (...) understands them as constituting only a conventional kind. Additionally, the paper shows that AT’s conventionalist stance about cognition, far from being an undesirable or useless position, offers some methodological virtues that might be timely and welcome in the agitated and revolutionary climate of current cognitive science.

Hutto and Satne, Philosophia propose to redefine the problem of naturalizing semantic content as searching for the origin of content instead of attempting to reduce it to some natural phenomenon. The search is to proceed within the framework of Relaxed Naturalism and under the banner of teleosemiotics which places Ur-intentionality at the source of content. We support the proposed redefinition of the problem but object to the proposed solution. In particular, we call for adherence to Strict Naturalism and replace teleosemiotics (...) with autopoietic theory of living beings. Our argument for these adjustments stems from our analysis of the flagship properties of Ur-intentionality: specificity and directedness. We attempt to show that the first property is not unique to living systems and therefore poses a problem of where to place a demarcation line for the origin of content. We then argue that the second property is a feature ascribed to living systems, not their intrinsic part and therefore does not form a good foundation for the game of naturalizing content. In conclusion we suggest that autopoietic theory can not only provide a competitive explanation of the basic responding of pre-contentful organisms but also clarify why Ur-intentionality is attributed to them in such an intuitive manner.

Recently, Michael Wheeler has argued that despite its sometimes revolutionary rhetoric, the so called 4E cognitive movement, even in the guise of ‘radical’ enactivism, cannot achieve a full revolution in cognitive science. A full revolution would require the rejection of two essential tenets of traditional cognitive science, namely internalism and representationalism. Whilst REC might secure antirepresentationalism, it cannot do the same, so Wheeler argues, with externalism. In this paper, expanding on Wheeler’s analysis, we argue that what compromises REC’s externalism is (...) the persistence of cognitively relevant asymmetries between its purported cognitive systems and the environment. Complementarily, we argue that an antirepresentationalist ancestor of enactivism, the autopoietic theory of cognition, is able to deliver and secure externalism, thus offering the explosive combination that Wheeler claims us needed for a revolution in cognitive science.

Varela, Thompson, and Rosch illustrated their original presentation of the enactive theory of cognition with the example of a simple cellular automaton. Their theory was paradigmatically anti-computational, and yet automata similar to the one that they describe have typically been used to illustrate theories of computation, and are usually treated as abstract computational systems. Their use of this example is therefore puzzling, especially as they do not seem to acknowledge the discrepancy. The solution to this tension lies in recognizing a (...) hidden background assumption, shared by both Varela, Thompson, and Rosch and the computational theories of mind which they were responding to. This assumption is that computation requires representation, and that computational states must bear representational content. For Varela, Thompson, and Rosch, representational content is incompatible with cognition, and so from their perspective the automaton that they describe cannot, despite appearances, be computational. However, there now exist several accounts of computation that do not make this assumption, and do not characterize computation in terms of representational content. In light of these recent developments, we will argue that it is quite straightforward to characterize the enactive automaton as a non-representational computing mechanism, one that we do not think they should have any objections to.

Traditionally, computational theory (CT) and dynamical systems theory (DST) have presented themselves as opposed and incompatible paradigms in cognitive science. There have been some efforts to reconcile these paradigms, mainly, by assimilating DST to CT at the expenses of its anti-representationalist commitments. In this paper, building on Piccinini’s mechanistic account of computation and the notion of functional closure, we explore an alternative conciliatory strategy. We try to assimilate CT to DST by dropping its representationalist commitments, and by inviting CT to (...) recognize the functionally closed nature of some computational systems. (shrink)

In contrast to Capra’s interpretation of Maturana’s work, I argue that the autopoietic theory does not establish an intrinsic, necessary link between life and cognitive/mental phenomena, and that given its functionalist approach, the theory helps very little to overcome the Cartesian division between mind and body.

What is or should be the place of the ethical dimension in a general enactive theory of sociality? How should such a dimension be understood and articulated within the more general picture of the enactive approach to social life? In this paper, building on Emmanuel Levinas’ philosophy, we argue that ethics should be understood as a distinct dimension of the complex and multidimensional phenomenon of sociality; a dimension of radical otherness that intertwines with but does not reduce to the intersubjective (...) dynamics of social life. In showing the particular place that the ethical dimension occupies in the general picture of sociality, we show, following Levinas, why sociality is more than intersubjectivity and how enactivism, if interested in a comprehensive account of ethics, would benefit from this insight.

The strong version of the life-mind continuity thesis claims that mind can be understood as an enriched version of the same functional and organizational properties of life. Contrary to this view, in this paper I argue that mental phenomena offer distinctive properties, such as intentionality or representational content, that have no counterpart in the phenomenon of life, and that must be explained by appealing to a different level of functional and organizational principles. As a strategy, and following Maturana’s autopoietic theory (...) of cognition, I introduce a conceptual distinction between mind and cognition. I argue that cognition corresponds to the natural behaviour that every living being exhibits in the realization of its existence, and that, viewed in that way, cognition is a dynamic process of structural coupling that, unlike mental phenomena, involves no representational contents. On the basis of this distinction, I try to show that while life suffices for cognition, it does not suffice for mind. That is, that the strong continuity is not between life and mind but between life and cognition. (shrink)
