Matthew Isaac Harvey’s main interests are the relation between distributed and enactive theories of language and the philosophy of agency and techniques. His PhD is focused on replacing representations (that’s the catchphrase) in linguistic theory, both as a concept and as a suite of terms and associated ways of thinking. With that in mind, he explores the use of agent-based modeling as a research tool in distributed and ecological linguistics, where the aim is to produce emergent phenomena that are recognizably language-like but cannot be traced directly to representational capacities of individual agents.

Open peer commentary on the article “Lived Experience and Cognitive Science Reappraising Enactivism’s Jonasian Turn” by Mario Villalobos & Dave Ward. Upshot: We argue that Villalobos and Ward’s criticism misses two crucial aspects of Varelian enactivism. These are, first, that enactivism attempts to offer a rigorous scientific justification for its teleological claims, and second, that enactivism in fact pays too little attention to the nature of human phenomenology and intentionality, rather than anthropomorphically over-valuing it.

This is nominally a book review of Hutto and Myin’s Radicalizing Enactivism: Basic Minds Without Content (The MIT Press, 2013). But it is a narrowly focused and highly prejudicial review, which presents an analysis of a contradiction at the heart of the book. Radicalizing Enactivism is a powerful and original philosophical argument against representations in cognition, but it repeatedly endorses an old-fashioned representationalism about language. I show that this contradiction arises from the authors’ unexamined, reflexive adoption of traditional linguistic concepts and terminology, which presuppose a representational interpretation of linguistic capacities and phenomena. The key piece of evidence for this analyses is the separability of Hutto and Myin’s substantive remarks on the ontogeny of language-dependent cognitive capacities, which they explain in terms of scaffolding and decoupling, from the representational gloss on those remarks that they present as if it were simply identical with observed empirical matters of fact. They follow a model laid out in Hutto’s earlier work, in which everyday linguistic activity is understood as instantiating abstract public vehicles with representational content (i.e., sentences which express propositions). I argue that this model is susceptible both to pre-existing arguments against representational theories of language and to a variant of their own ‘Hard Problem of Content’. The take-away lesson from Radicalizing Enactivism is that anti-representationalist accounts of language remain unconvincing – even to radicals like Hutto and Myin – because they have no way of explaining the phenomenal experience of literate speakers, wherein words really do feel like instantiations of abstract forms with determinable semantics. I suggest that anti-representationalists can address this by focusing on the ways in which patterns of attention become stabilized and interpersonally regularized as we learn language.

Open peer commentary on the article “From Problem Solving to Problem Posing, and from Strategies to Laying Down a Path in Solving: Taking Varela’s Ideas to Mathematics Education Research” by Jérôme Proulx & Jean-François Maheux. Upshot: The target article succeeds in conceptualizing mathematical problem-solving as a form of organism-environment coupling. So conceived, it is a suitable subject for both enactive and ecological descriptions, and is open to embodied, dynamical explanations that have no need for cognitivist models. In other words, Proulx and Maheux have shown how to get across the “cognitive gap.”

Upshot: We agree with commenters that enactivism incorporates a broad variety of methodologies, metaphysical stances, concepts, and investigative approaches, and that this is a good thing. However, we remain concerned that autonomy and sense-making are problematic concepts for post-Varelian enactivism, and that they form the foundations of a conceptual framework that may hamper the development of effective explanations for cognitive activity, as well as the paradigmatic aspirations of this particular enactivist approach.

Context: Distributed language and interactivity are central members of a set of concepts that are rapidly developing into rigorous, exciting additions to 4E cognitive science. Because they share certain assumptions and methodological commitments with enactivism, the two have sometimes been confused; additionally, while enactivism is a well-developed paradigm, interactivity has relied more on methodological development and on a set of focal examples. Problem: The goal of this article is to clarify the core conceptual commitments of both interactivity-based and enactive approaches to cognitive science by contrasting the two and highlighting their differences in assumptions, focus, and explanatory strategies. Method: We begin with the shared commitments of interactivity and enactivism - e.g., antirepresentationalism, naturalism, interdisciplinarity, the importance of biology, etc. We then give an overview of several important varieties of enactivism, including sensorimotor and anti-representationalist enactivism, and then walk through the history of the “core” varieties, taking care to contrast Maturana’s approach with that of Varela and the current researchers following in Varela’s footsteps. We then describe the differences between this latter group and interactivity-based approaches to cognitive science. Results: We argue that enactivism’s core concepts are explanatorily inadequate in two ways. First, they mis-portray the organization of many living systems, which are not operationally closed. Second, they fail to realize that most epistemic activity (i.e., “sense-making”) depends on engagement with non-local resources. Both problems can be dealt with by adopting an interactivity-based perspective, in which agency and cognition are fundamentally distributed and involve integration of non-local resources into the local coupling of organism and environment. Implications: The article’s primary goal is theoretical clarification and exposition; its primary implication is that enactive concepts need to be modified or extended in some way in order to explain fully many aspects of cognition and directed biological activity. Or, read another way, the article’s primary implication is that interactivity already provides a rich set of concepts for doing just that, which, while closely allied with enactivism in several ways, are not enactivist concepts. Constructivist content: The article consists entirely of a comparison between two constructivist fields of theory. Key Words: Interactivity, enactivism, distributed language, radical embodied cognitive science, ecological psychology, autonomy.
