Information is a central notion for cognitive sciences and neurosciences, but there is no agreement on what it means for a cognitive system to acquire information about its surroundings. In this paper, we approximate three influential views on information: the one at play in ecological psychology, which is sometimes called information for action; the notion of information as covariance as developed by some enactivists, and the idea of information as a minimization of uncertainty as presented by Shannon. Our main thesis is that information for action can be construed as covariant information, and that learning to perceive covariant information is a matter of minimizing uncertainty through skilled performance. We argue that the agent’s cognitive system conveys information for acting in an environment by minimizing uncertainty about how to achieve intended goals in that environment. We conclude by reviewing empirical findings that support our view by showing how direct learning, seen as an instance of ecological rationality at work, is how mere possibilities for action are turned into embodied know-how. Finally, we indicate the affinity between direct learning and sense-making activity.

I advance the Radically Enactive Cognition (REC) program by developing Hutto & Satne’s (2015) and Hutto & Myin’s (2017) idea that contentful cognition emerges through sociocultural activities, which require a contentless form of intentionality. Proponents of REC then face a functional challenge: what is the function of higher cognitive skills, given the empirical findings that engaging in higher-cognitive activities is not correlated with cognitive amelioration (Kornblith, 2012)? I answer that functional challenge by arguing that higher cognition is an adaptive tool of the social systems we are embedded in, therefore, it is not necessarily aimed at achieving better cognitive states. In order to do so, I suggest interpreting key insights from autopoietic enactivism through REC lenses.

Rational beliefs and actions are typically evaluated against certain benchmarks e.g., those of classical logic or probability theory. Rationality therefore is traditionally taken to involve some sort of reasoning, which in turn implies contentful cognition. Radically Enactive (and Embodied) views of Cognition (REC), on the other hand, claim that not all cognition is contentful. In order to show that rationality does not need to lie outside of REC’s scope of radicalizing cognition, I develop a Radically Enactive notion of Rationality (RER), according to which rationality is embodied, situated and contentless. For RER, an organism acts rationally insofar as it sustains a proficient interaction with its environment, which in turn requires the coordination of cognitive abilities in accordance with environmental constraints. Rationality is thus distinguished from reasoning, for reasoning is understood as a capacity to coordinate representational cognitive abilities.

Our objective in this paper is twofold: first, we intend to address the tenability of the enactivist middle way between realism and idealism, as it is proposed in The Embodied Mind. We do so by taking the enactivist conception of bringing forth a world literally in three conceptual levels: enaction, niche construction and social construction. Based on this proposal, we claim that enactivism is compatible with the idea of an independent reality without committing to the claim that organisms have cognitive access to a world composed of properties specified prior to any cognitive activity. Our second goal is to show that our literal interpretation of bringing forth a world not only sustains the legitimacy of the middle way, but it also allows us to revive the conception of evolution as natural drift – which is perhaps the least examined aspect of the original enactivist theory and is central to the understanding of cognition in an enactive way. Natural drift focuses on how structural couplings between organism and environment trigger viable pathways of maintenance and reproduction, instead of selecting the most adapted trait to a pregiven environment. Thus, although enactivists typically do not explore the consequences of their views regarding evolutionary dynamics, we show how natural drift provides a suitable starting point.

Key words: enactivism, evolution, niche construction, social construction, natural drift.

We advance a critical examination of two recent branches of the enactivist research program, namely, Radically Enactive Cognition and Linguistic Bodies. We argue that, although these approaches may look like diverging views within the wider enactivist program, when appraised in a conciliatory spirit, they can be interpreted as developing converging ideas. We examine how the notion of know-how figures in them to show an important point of convergence, namely, that the normativity of human cognitive capacities rests on shared know-how. Radical enactivism emphasizes the diachronic dimension of shared know-how, and linguistic bodies emphasize the synchronic one. Given that know-how is a normative notion, it is subject to success conditions. We then argue it implies basic content, which is the content of the successful ongoing interactions between agent(s) and environment. Basic content does not imply accuracy conditions and representational content, so it evades Hutto and Myin’s Hard Problem of Content. Moreover, this account is amenable to the central claim by Di Paolo et al. that the participatory sense-making relations at play in linguistic exchanges are explained in continuity with explanations of biological organization and sensorimotor engagements.

Key words: radically enactive cognition, linguistic bodies, shared know-how, ur-intentionality, participatory sense-making, basic content

Ecological-enactive approaches to cognition aim to explain cognition in terms of the dynamic coupling between agent and environment. Accordingly, cognition of one’s immediate environment (which is sometimes labeled “basic” cognition) depends on enaction and the picking up of affordances. However, ecological-enactive views supposedly fail to account for what is sometimes called “higher” cognition, i.e., cognition about potentially absent targets, which therefore can only be explained by postulating representational content. This challenge levelled against ecological-enactive approaches highlights a putative explanatory gap between basic and higher cognition. In this paper, we examine scientific cognition – a paradigmatic case of higher cognition – and argue that it shares fundamental features with basic cognition, for enaction and affordance selection are central to the scientific enterprise. Our argument focuses on modeling, and on how models promote scientific understanding. We base our argument on a non-representational account of scientific understanding and on the material engagement theory, for models are hereby conceived as material objects designed for scientific engagements. Having done so, we conclude that the explanatory gap is significantly less threatening to the ecological-enactive approach than it might appear.
