This paper explores the enactive approach in cognitive science with an eye on the later Wittgenstein’s philosophy. The aim is not that of answering the question: was Wittgenstein an ante litteram enactivist? He was not, because he was not an ante litteram (cognitive) scientist of any kind. The aim, conversely, is that of answering the question: can enactivism be Wittgensteinian? In answering positively, it will be argued that a Wittgensteinian framework can help enactive cognitive scientists in dissolving certain old problems which they sometimes seem not to be able to get rid of. After the Introduction, the first two sections of the paper concern the Wittgensteinian standpoint on psychological concepts (Section 2) and the enactivist approach in its general terms (Section 3). Section 4 attempts a closer examination of some key concepts – chiefly representations, the inner, the “explanatory gap,” the “hard problem” of consciousness – considering both the enactivists’ and Wittgenstein’s attitude towards them. The Conclusion surmises the benefits of a Wittgensteinian perspective also hinting at some other problems which it can help to clarify.

Key words: wittgenstein, enactivism, explanatory gap, hard problem, hutto.

Excerpt: Describing language in the light of the enactive paradigm is a most challenging issue: language is to be reconsidered in terms of sensorimotor interactions with an environment in which both the individual and the environment are modified, in which not one,but several individuals are involved – an experience that is, all in one, that of the speaker and hearer at the instant of uttering or thinking; that of the child developing into an adult through social intercourse; that of the tribe turning to a full-fledged civilization; and that of the linguist interfering with his object of scrutiny by linguistic means. As a selection has to be made, this chapter will primarily focus on the immediate experience of languaging, and secondarily broach more general subjects like acquisition and evolution.

The main contribution of this paper is a naturalized account of the phenomenon of computation. The key idea for the development of this account is the identification of the notion of syntactical processing (or information processing) with the dynamical evolution of a constrained physical process, based on the observation that both evolve according to an arbitrary set of rules. This identification, in turn, revealed that, from the physical point of view, computation could be understood in terms of the operation of a component subdivided into two parts, (a) the constrained process and (b) the constraints that control its dynamics, where the interactions with the rest of the system are mediated by configurational changes of the constrained process. The immediate consequence of this analysis is the observation that this notion of computation can be readily integrated into the enactive paradigm of cognition.

In this paper, we argue for a theoretical separation of the free-energy principle from Helmholtzian accounts of the predictive brain. The free-energy principle is a theoretical framework capturing the imperative for biological self-organization in information-theoretic terms. The free-energy principle has typically been connected with a Bayesian theory of predictive coding, and the latter is often taken to support a Helmholtzian theory of perception as unconscious inference. If our interpretation is right, however, a Helmholtzian view of perception is incompatible with Bayesian predictive coding under the free-energy principle. We argue that the free energy principle and the ecological and enactive approach to mind and life make for a much happier marriage of ideas. We make our argument based on three points. First we argue that the free energy principle applies to the whole animal–environment system, and not only to the brain. Second, we show that active inference, as understood by the free-energy principle, is incompatible with unconscious inference understood as analagous to scientific hypothesis-testing, the main tenet of a Helmholtzian view of perception. Third, we argue that the notion of inference at work in Bayesian predictive coding under the free-energy principle is too weak to support a Helmholtzian theory of perception. Taken together these points imply that the free energy principle is best understood in ecological and enactive terms set out in this paper.

Key words: Free-energy principle, predictive-coding, skilled intentionality, affordances, enaction, active inference, action-readiness, metastability.

Theories of brain function have evolved through multiple stages. The first proposition was that brain networks support a set of reflex responses, with current sensory inputs producing immediate motor outputs. The behaviorist paradigm suggested that actions can always be explained as a response to immediate external cues. In response to these views, the cognitive paradigm argued that behavior cannot be understood simply as input–output functions because the hidden layers of brain generate unpredictability. The central processing was termed “cognition.” Here we propose a neuroscience-based model of cognition. Our core hypothesis is that cognition depends on internal models of the animal and its world, where internally generated sequences can serve to perform “what if” scenarios and anticipate the possible consequences of alternative actions without actually testing them, and aid in the decisions of overt actions. We support our hypotheses by several examples of recent experimental findings and show how externally guided cell assembly sequences become internalized to support cognitive functions.

This book asks the sciences of the mind to test their own boundaries, demanding that they account for a number of cognitive and experiential phenomena that are at the edge of the very possibility to cognize. We believe that this is a foundational challenge for the enactive approach to the mind, and, moreover, it is a challenge that – if actually won – might offer a persuasive theoretical framework even to those who have so far been skeptical about enactivism’s capacity to deal with higherlevel cognition.

The enactive approach replaces the classical computer metaphor of mind with emphasis on embodiment and social interaction as the sources of our goals and concerns. Researchers from a range of disciplines unite to address the challenge of how to account for the more uniquely human aspects of cognition, including the abstract and the nonsensical.

Excerpt: This essay has two parts. In the first, I advance the main theses of the enactivist approach to perception and experience. Moreover, embracing Alvin Goldman’s concept of “enactment imagination,” I argue that the imagination works by simulating (or enacting) a hypothetical perceptual experience, and that this accounts for its experiential quality. In the second part, I develop an enactivist model of the reader’s imagination, suggesting that narrative texts are sets of instructions for the enactment of a storyworld. I also question the view that fictional consciousnesses are represented in narrative texts, adding some remarks concerning the relationship between narrative and qualia (defined as the intrinsic, ineffable qualities of our experience). The analogy that steers me through this argument is that, in their imaginative engagement with narratives, readers are like blind people tapping their way around with a cane. Every tap of the cane corresponds to the reader’s being invited to imagine a nonexistent object.

Embodied Cognition represents the most important news in cognitive psychology in the last twenty years. The basis of its research program is the idea that cognitive processes depend, mirror, and are influenced by bodily control systems. A whole class of novel perspectives entered into the psychologists’ agenda only after the emergence and success of EC. In the paper we will deal with some of the main topics debated within EC, from the discussion on the role of representation, to the relationship with enactivism, with functionalism and with the extended mind view. Against an interpretation according to which EC is simply an evolution of the classical cognitivist program, we will focus on the aspects that highlight crucial discontinuities with it, suggesting instead that the EC perspective is indebted to previous theoretical traditions such as American pragmatism, ecological psychology and phenomenology. In the present paper we will discuss some of the most important achievements of EC in different areas of experimental research, from the study of affordances to that of the bodily experience, from the investigation on emotions to that on language. Our aim is to force the Italian public, particularly recalcitrant to EC, to critically reflect on the debts to previous traditions. Relevance: The paper reviews embodied theories with a special focus on enactivist approaches.
