Open peer commentary on the article “Decentering the Brain: Embodied Cognition and the Critique of Neurocentrism and Narrow-Minded Philosophy of Mind” by Shaun Gallagher. Abstract: Simulation theory and theory theory are interaction accounts of theory of mind that have been neurocentrically characterized. A hybrid of these theories approximates the interaction theory of social cognition, and can be described in an indexical-symbolic processing framework.

Predictive processing (PP) approaches to the mind are increasingly popular in the cognitive sciences. This surge of interest is accompanied by a proliferation of philosophical arguments, which seek to either extend or oppose various aspects of the emerging framework. In particular, the question of how to position predictive processing with respect to enactive and embodied cognition has become a topic of intense debate. While these arguments are certainly of valuable scientific and philosophical merit, they risk underestimating the variety of approaches gathered under the predictive label. Here, we first present a basic review of neuroscientific, cognitive, and philosophical approaches to PP, to illustrate how these range from solidly cognitivist applications – with a firm commitment to modular, internalistic mental representation – to more moderate views emphasizing the importance of ‘body-representations’, and finally to those which fit comfortably with radically enactive, embodied, and dynamic theories of mind. Any nascent predictive processing theory (e.g., of attention or consciousness) must take into account this continuum of views, and associated theoretical commitments. As a final point, we illustrate how the Free Energy Principle (FEP) attempts to dissolve tension between internalist and externalist accounts of cognition, by providing a formal synthetic account of how internal ‘representations’ arise from autopoietic self-organization. The FEP thus furnishes empirically productive process theories (e.g., predictive processing) by which to guide discovery through the formal modelling of the embodied mind.

Key words: Predictive processing, embodied cognition, interoception, active inference, connectionism, computationalism, enactivism.

Open peer commentary on the article “Decentering the Brain: Embodied Cognition and the Critique of Neurocentrism and Narrow-Minded Philosophy of Mind” by Shaun Gallagher. Abstract: I intend to explore some of the implications of Gallagher’s target article. Retracing the circulation of concepts such as “embodied,” “embedded,” “extended,” etc. in social epidemiology, feminist science and epigenetics, I advocate for studying E-approaches from an epistemological, historical and political viewpoint in order to critically assess the transformations of knowledge that we are currently witnessing.

Upshot: The authors offer a theory of agency that is general enough to apply to whole organisms and single cells, and meaningful enough to highlight problems that embodied cognition theory has overlooked. The authors insist that the interesting thing about minds is what goes on in between activities; this leaves unclear what a specifically enactivist empirical program could look like. But the book can be read as a contribution to a broader project of instituting a full-blown post-cognitivist science of the mind.

Open peer commentary on the article “Towards a Dialogue Among Constructivist Research Programs” by Gastón Becerra & José Antonio Castorina. Upshot: The target article claims that constructivism should be regarded as a manifold movement, but not as a unique philosophical doctrine. This commentary evaluates the legitimacy of this claim.

Is cognition limited to psychological representations and their linguistic counterparts? Is meaning restricted to propositional contents? “Sequentiality of Meaning and Cognitive Forms” challenges the traditional assumptions in the answers to these questions. It scrutinizes the systems that produce cognitive forms from their elements and the operations they realize. These systems are systems based on meaning. Meaning systems are psychic and social systems. For our purpose, the notion of meaning is restricted to the psychic and social concretions of the interpretative processing of signals. Knowledge is described across two paths: i) as a process resulting in a cognitive form, traditionally called representation, because it has been exemplified and scrutinized in psychic systems articulated through the elements of consciousness (representations); ii) according to operations with multiple instantiation, and therefore not limited to human consciousness or psychic representations. Relevance: The text addresses the core of the constructivism’s claim concerning the operative conditioning of knowledge construction. It explores the acquisition of self-reference in systems mobilising cognitive forms, such as communicative and psychic systems, in order to understand how cognition contributes to the modification or orientation of their elements.

Key words: Cognition, meaning, communication, psychic systems, consciousness.

Upshot: University engineering qualifications are accredited according to various international accords that are perceived as a restrictive factor in curricula redesign. I argue that this may not be the case owing to the discipline-independent wide-ranging content that may populate the qualifications. Also, I point out that the educator’s teaching style is their choice and that educators may act as agents of change bringing ethical changes to their curricula. Finally, I question the role of the teacher and its future relevance in competition with artificial intelligence.

Context: South African public universities are currently undergoing a transitional period as they traverse the sensitive road of curriculum redesign that achieves an inclusive approach to education for the goal of the decolonisation of knowledge. Problem: Many classrooms have students from several cultural backgrounds yet in these spaces there is often a single dominant discourse on offer. An ethical question is raised in terms of what content should be addressed in the classroom. Method: An approach to curricula design as a conversation is presented. The philosophical aspects underlying shifts in epistemology are presented following an eclectic approach to curricula design that embraces second-order science in achieving the ongoing goal of decolonisation. The method used to achieve this goal is conversational heterarchical curriculum design assuming non quidem tabula rasa. Students can act as reference points (Nunataks) for curricula design, thus reducing the abstraction in the syllabus. Results: A heterarchical conversational approach offers a platform whereby social justice may be addressed in the classroom by providing a means by which the students’ own epistemology is embraced within the curriculum as the students provide the trajectory for the course content based on their own epistemology. A dynamic curriculum is then available that has immediate use in the communities that the students reside in. Students demonstrate understanding of the content as it is tied to their own way of knowing. Implications: The benefits of this approach include moving away from defining science according to a realist view. Educators may accept the idea that knowledge is not impartial and that method is tied to epistemology. When the observer is included in science, an awareness arises that theories (at least in the social sciences) affect what is studied, which in turn affects society. Constructivist content: The approach builds on von Foerster’s ideas on reflexivity. Pask’s conversation theory is a vehicle for the attainment of reflexive conversational teaching and learning.

Key words: Adaptation, curriculum design, conversation theory, cybernetics, decolonisation, ethics, heterarchy, nunatak, reflexivity, second-order science, ubuntuism.

Upshot: Furthering the commentators’ input, we seek to clarify the reasons that fueled some of our decisions when constructing the analytical framework introduced in the target article. We reassert our case of pursuing a pluralistic and dialogic constructivism. In particular we discuss the proposal of axes and tensions, such as knowledge/reality and individual/society. Finally, we discuss some of the alternative proposals suggested by the commentators, which are mainly based on what the constructivist research programs have in common.

Context: Constructivist epistemology is not a doctrinal set of clear and consistent theses and assumptions but a movement full of tensions, with minimally integrated lines of discussions. Problem: This situation explains why it is so difficult to come up with a general definition of constructivist epistemology that could serve as a starting point to study its several research programs systematically and comparatively. Method: We compare the constructivist epistemologies of Jean Piaget, Ernst von Glasersfeld, Humberto Maturana, and Niklas Luhmann regarding tensions between knowledge/reality and individual/society. Results: Our comparison leads to a general definition of constructivist epistemology as a heterogeneous movement problematizing certain dualities - such as subject/object, knowledge/reality, or individual/society - that have been shown to be central for epistemological inquiry. We argue that such dualisms can be used as dimensions for critical analysis, comparison, and discussion among the different research programs, and that, at the same time, they would allow us to analyze the general strategies characterizing such programs. The comparative and critical analysis of the programs by way of the aforementioned tensions results in an organized presentation highlighting their convergences, divergences, and singularities.
