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.

This work addresses the autonomous organization of biological systems. It does so by considering the boundaries of biological systems, from individual cells to Home sapiens, in terms of the presence of Markov blankets under the active inference scheme – a corollary of the free energy principle. A Markov blanket defines the boundaries of a system in a statistical sense. Here we consider how a collective of Markov blankets can self-assemble into a global system that itself has a Markov blanket; thereby providing an illustration of how autonomous systems can be understood as having layers of nested and self-sustaining boundaries. This allows us to show that: (i) any living system is a Markov blanketed system and (ii) the boundaries of such systems need not be co-extensive with the biophysical boundaries of a living organism. In other words, autonomous systems are hierarchically composed of Markov blankets of Markov blankets – all the way down to individual cells, all the way up to you and me, and all the way out to include elements of the local environment.

Open peer commentary on the article “The Past, Present and Future of Time-Consciousness: From Husserl to Varela and Beyond” by Shaun Gallagher. Upshot: In this commentary I invert Gallagher’s argument and argue that the account he gives of temporality should be applied to enactive cognition across the board. Instead of enactivising phenomenological accounts of time-consciousness, I suggest Gallagher ought also to be read as arguing for a temporalizing of enactive cognition.

Excerpt: 4E cognitive science is a broad church housing a number of theoretical perspectives that to varying degrees conflict with each other (Shapiro 2010). In this chapter I will argue that the debates within 4E cognitive science surrounding extended cognition boil down to competing ontological conceptions of cognitive processes. The embedded theory (henceforth EMT) and the family of extended theories of cognition (henceforth EXT) disagree about what it is for a state or process to count as cognitive. EMT holds that cognitive processes are deeply dependent on bodily interactions with the environment in ways that more traditionally minded cognitive scientists might find surprising. The strong dependence of some cognitive processes on bodily engagements with the world notwithstanding, EMT claims that cognitive processes are nevertheless wholly realized by systems and mechanisms located inside of the brain. Thus advocates of EMT continue to interpret the concept of cognition along more or less traditional lines (Adams and Aizawa 2008; Rupert 2009). That is to say, they think of cognitive processes as being constituted by computational, rule-based operations carried out on internal representational structures that carry information about the world.

Open peer commentary on the article “Précis of The Philosophy of Affordances” by Manuel Heras-Escribano. Abstract: My commentary takes up the two issues Heras-Escribano focusses on in the precis of his book: the ontology and normativity of affordances. The dispositional account of affordances Heras-Escribano endorses is standardly taken to be in opposition to a relational ontology. I first set out to identify what is at issue in this debate. Second, I evaluate the considerations Heras-Escribano takes to favour a dispositional theory of affordances. I argue they are not decisive. Finally, I turn to the issue of the normativity of affordances. I argue against Heras-Escribano’s ontological separation of the normative from the nomological.

In this programmatic paper we explain why a radical embodied cognitive neuroscience is needed. We argue for such a claim based on problems that have arisen in cognitive neuroscience for the project of localizing function to specific brain structures. The problems come from research concerned with functional and structural connectivity that strongly suggests that the function a brain region serves is dynamic, and changes over time. We argue that in order to determine the function of a specific brain area, neuroscientists need to zoom out and look at the larger organism-environment system. We therefore argue that instead of looking to cognitive psychology for an analysis of psychological functions, cognitive neuroscience should look to an ecological dynamical psychology. A second aim of our paper is to develop an account of embodied cognition based on the inseparability of cognitive and emotional processing in the brain. We argue that emotions are best understood in terms of action readiness (Frijda, 1986, 2007) in the context of the organism’s ongoing skillful engagement with the environment (Rietveld, 2008; Bruineberg and Rietveld, 2014; Kiverstein and Rietveld, 2015, forthcoming). States of action readiness involve the whole living body of the organism, and are elicited by possibilities for action in the environment that matter to the organism. Since emotion and cognition are inseparable processes in the brain it follows that what is true of emotion is also true of cognition. Cognitive processes are likewise processes taking place in the whole living body of an organism as it engages with relevant possibilities for action.

Enactive approaches to cognitive science aim to explain human cognitive processes across the board without making any appeal to internal, content-carrying representational states. A challenge to such a research programme in cognitive science that immediately arises is how to explain cognition in so-called ‘representation-hungry’ domains. Examples of representation-hungry domains include imagination, memory, planning and language use in which the agent is engaged in thinking about something that may be absent, possible or abstract. The challenge is to explain how someone could think about things that are not concretely present in their environment other than by means of an internal mental representation. We call this the ‘Representation-Hungry Challenge’ (RHC). The challenge we take up in this article is to show how hunger for representations could possibly be satisfied by means other than the construction and manipulation of internal representational states. We meet this challenge by developing a theoretical framework that integrates key ideas drawn from enactive cognitive science and ecological psychology. One of our main aims is thus to show how ecological and enactive theories as non-representational and non-computational approaches to cognitive science might work together. From enactive cognitive science, we borrow the thesis of the strict continuity of lower and higher cognition. We develop this thesis to argue against any sharp conceptual distinction between higher and lower cognition based on representation-hunger. From ecological psychology, we draw upon our earlier work on the rich landscape of affordances. We propose thinking of so-called representation-hungry cognition in terms of temporally extended activities in which the agent skilfully coordinates to a richly structured landscape of affordances. In our framework, putative cases of representation-hungry cognition are explained by abilities to coordinate nested activities to an environment structured by interrelated socio-material practices. The RHC has often figured in arguments for the limitations of non-representational approaches to cognitive science. We showcase the theoretical resources available to an integrated ecological-enactive approach for addressing this type of sceptical challenge.
