Context: The enactivist tradition, out of which neurophenomenology arose, rejects various internalisms – including the representationalist and information-processing metaphors – but remains wedded to one further internalism: the claim that the structure of perceptual experience is directly, constitutively linked only to internal, brain-based dynamics. Problem: I aim to reject this internalism and defend an alternative analysis. Method: The paper presents a direct-realist, externalist, sensorimotor account of perceptual experience. It uses the concept of counterfactual meaningful action to defend this view against various objections. Results: This account of experience matches certain first-person features of experience better than an internalist account could. It is fully tractable as “normal science.” Implications: The neuroscientific conception of brain function should change from that of internal representation or modelling to that of enabling meaningful, embodied action in ways that constitutively involve the world. Neurophenomenology should aim to match the structure of first-person experience with the structure of meaningful agent-world interactions, not with that of brain dynamics. Constructivist content: The sensorimotor approach shows us what external objects are, such that we may enact them, and what experience is, such that it may present us with those enacted objects.

This paper seeks to identify, clarify, and perhaps rehabilitate the virtual reality metaphor as applied to the goal of understanding consciousness. Some proponents of the metaphor apply it in a way that implies a representational view of experience of a particular, extreme form that is indirect, internal and inactive (what we call “presentational virtualism”). In opposition to this is an application of the metaphor that eschews representation, instead preferring to view experience as direct, external and enactive (“enactive virtualism”). This paper seeks to examine some of the strengths and weaknesses of these virtuality-based positions in order to assist the development of a related, but independent view of experience: virtualist representationalism. Like presentational virtualism, this third view is representational, but like enactive virtualism, it places action centre stage, and does not require, in accounting for the richness of visual experience, global representational “snapshots” corresponding to the entire visual field to be tokened at any one time.

Context: Challenges by embodied, enactive, extended and ecological approaches to cognition have provided good reasons to shift away from neurocentric theories. Problem: Classic cognitivist accounts tend towards internalism, representationalism and methodological individualism. Such accounts not only picture the brain as the central and almost exclusive mechanism of cognition, they also conceive of brain function in terms that ignore the dynamical relations among brain, body and environment. Method: I review four areas of research (perception, action/agency, self, social cognition) where enactivist accounts have shown alternative ways of thinking about the brain. Results: Taken together, such analyses form a comprehensive alternative to the classic conceptions of cognitivist, computational neuroscience. Implications: Such considerations motivate the need to re-think our understanding of how the brain itself works. They suggest that the best explanation of brain function may be found in the mixed vocabularies of embodied and situated cognition, developmental psychology, ecological psychology, dynamic systems theory, applied linguistics, the theory of affordances and material engagement, rather than the narrow vocabulary of computational neuroscience. Constructivist content: This account is consistent with an enactivist-constructivist approach to cognition.

Key words: Internalism, perception, agency, autonomy, self, social cognition, predictive processing, enactivism.

Intentionality and consciousness are the fundamental kinds of mental phenomena. Although they are widely regarded as being entirely distinct some philosophers conjecture that they are intimately related. Prominently it has been claimed that consciousness can be best understood in terms of representational facts or properties. Representationalist theories vary in strength. At their core they seek to establish that subjective, phenomenal consciousness (of the kind that involves the having of first-personal points of view or perspectives on the world – perspectives that incorporate experiences with specific phenomenal characters) is either exhausted by, or supervenes on, capacities for mental representation. These proposals face several serious objections.

This paper targets the constitutive basis of social cognition. It begins by describing the traditional and still dominant cognitivist view. Cognitivism assumes internalism about the realisers of social cognition; thus, the embodied and embedded elements of intersubjective engagement are ruled out from playing anything but a basic causal role in an account of social cognition. It then goes on to advance and clarify an alternative to the cognitivist view; namely, an enactive account of social cognition. It does so first by articulating a diachronic constitutive account for how embodied engagement can play a constitutive role in social cognition. It then proceeds to consider an objection; the causal-constitutive fallacy (Adams & Aizawa, 2001, 2008; Block, 2005) against enactive social cognition. The paper proceeds to deflate this objection by establishing that the distinction between constitution and causation is not co-extensive with the distinction between internal constitutive elements and external causal elements. It is then shown that there is a different reason for thinking that an enactive account of social cognition is problematic. We call this objection the ‘poverty of the interactional stimulus argument’. This objection turns on the role and characteristics of anticipation in enactive social cognition. It argues that anticipatory processes are mediated by an internally realised model or tacit theory (Carruthers, 2015; Seth, 2015). The final part of this paper dissolves this objection by arguing that it is possible to cast anticipatory processes as orchestrated as well as maintained by sensorimotor couplings between individuals in face-to-face interaction.

It is shown that the definition of the subject area of Haugenian ecolinguistics is methodologically inconsistent because of the implicit biomorphic metaphor, the language myth, and indiscrimination between the two different approaches to language known as cognitive internalism and cognitive externalism. A more consistent definition of language ecology is given, based on the biology of cognition as a theory of living systems; consequently, the subject area of ecolinguistics is defined differently, with a focus on the nature and function of language as a mode of organization of the living system (society) and its role in the development of the brain, thought, and mind. Relevance: Language ecology is defined, based on the biology of cognition

This paper tackles the problem of the nature of the space of perception. Based both on philosophical arguments and on results obtained from original experimental situations, it attempts to show how space is constituted concretely, before any distinction between the “inner” and the “outer” can be made. It thus sheds light on the presuppositions of the well-known debate between internalism and externalism in the philosophy of mind; it argues in favor of the latter position, but with arguments that are foundationally antecedent to this debate. We call the position we defend enactive externalism. It is based on experimental settings which, in virtue of their minimalism, make it possible both to defend a sensori-motor/enactive theory of perception; and, especially, to inquire into the origin of the space of perception, showing how it is concretely enacted before the controversy between internalism and externalism can even take place.

This paper explores some of the differences between the enactive approach in cognitive science and the extended mind thesis. We review the key enactive concepts of autonomy and sense-making. We then focus on the following issues: (1) the debate between internalism and externalism about cognitive processes; (2) the relation between cognition and emotion; (3) the status of the body; and (4) the difference between ‘incorporation’ and mere ‘extension’ in the body-mind-environment relation.

Context: As one of the major approaches within the philosophy of mathematics, constructivism is to be contrasted with realist approaches such as Platonism in that it takes human mental activity as the basis of mathematical content. Problem: Mathematical constructivism is mostly identified as one of the so-called foundationalist accounts internal to mathematics. Other perspectives are possible, however. Results: The notion of “meaning finitism” is exploited to tie together internal and external directions within mathematical constructivism. The various contributions to this issue support our case in different ways. Constructivist content: Further contributions from a multitude of constructivist directions are needed for the puzzle of an integrative, overarching theory of mathematical practice to be solved.

Key words: mathematical constructivism, conceptualism, internalism vs externalism, meaning finitism, mathematical practice

Recently, Michael Wheeler (2017) has argued that despite its sometimes revolutionary rhetoric, the so called 4E (embodied-embedded-enacted-extended) cognitive movement, even in the guise of ‘radical’ enactivism (REC), 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 (2017), 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 (i.e., antirepresentationalism plus externalism) that Wheeler claims us needed for a revolution in cognitive science.
