Proponents of enactivism should be interested in exploring what notion of action best captures the type of action–perception link that the view proposes, such that it covers all the aspects in which our doings constitute and are constituted by our perceiving. This article proposes and defends the thesis that the notion of sensorimotor dependencies is insufficient to account for the reality of human perception and that the central enactive notion should be that of perceptual practices. Sensorimotor enactivism is insufficient because it has no traction on socially dependent perceptions (SDPs), which are essential to the role and significance of perception in our lives. Since the social dimension is a central desideratum in a theory of human perception, enactivism needs a notion that accounts for such an aspect. This article sketches the main features of the Wittgenstein-inspired notion of perceptual practices as the central notion to understand perception. Perception, I claim, is properly understood as woven into a type of social practices that includes food, dance, dress, and music. More specifically, perceptual practices are the enactment of culturally structured, normatively rich techniques of commerce of meaningful multi- and intermodal perceptible material. I argue that perceptual practices explain three central features of SDP: attentional focus, aspects’ salience, and modal-specific harmony-like relations.

In this article, the author examines Colin Grant’s recent criticism of the so-called “interaction paradigm” and Jürgen Habermas’s universal pragmatics. Grant’s approach, which is presented as an open challenge to communication theories grounded in philosophical conceptions of communality and dialogue, can be construed as an exemplar of a radical constructivist approach to vital questions of contingency and incommensurability in communication studies. In response, the author outlines a classical pragmatist approach to the problem areas identified by Grant, with the aim of outlining how a pragmatist outlook can offer promising theoretical alternatives to universal pragmatics and radical constructivism. It is argued that moderate Peircean pragmatism, appropriately interpreted, can provide a philosophical platform capable of addressing issues of contingency, uncertainty, and autonomy in communication theory without succumbing to incommensurabilism, traditional objectivism, or nominalistic individualism.

Open peer commentary on the target article “Arguments Opposing the Radicalism of Radical Constructivism” by Gernot Saalmann. First paragraph: Although supportive of many of the positions taken by constructivists, pragmatists, and instrumentalists against “metaphysical realism,” the author Gernot Saalmann mounts arguments against all epistemological radicalisms, in favor of a critical realism. Ultimately he seeks “development of an antimetaphysical, non-objectivist epistemology” rooted in pragmatism.

Problem: There is currently a great deal of mysticism, uncritical hype, and blind adulation of imaginary mathematical and physical entities in popular culture. We seek to explore what a radical constructivist perspective on mathematical entities might entail, and to draw out the implications of this perspective for how we think about the nature of mathematical entities. Method: Conceptual analysis. Results: If we want to avoid the introduction of entities that are ill-defined and inaccessible to verification, then formal systems need to avoid introduction of potential and actual infinities. If decidability and consistency are desired, keep formal systems finite. Infinity is a useful heuristic concept, but has no place in proof theory. Implications: We attempt to debunk many of the mysticisms and uncritical adulations of Gödelian arguments and to ground mathematical foundations in intersubjectively verifiable operations of limited observers. We hope that these insights will be useful to anyone trying to make sense of claims about the nature of formal systems. If we return to the notion of formal systems as concrete, finite systems, then we can be clear about the nature of computations that can be physically realized. In practical terms, the answer is not to proscribe notions of the infinite, but to recognize that these concepts have a different status with respect to their verifiability. We need to demarcate clearly the realm of free creation and imagination, where platonic entities are useful heuristic devices, and the realm of verification, testing, and proof, where infinities introduce ill-defined entities that create ambiguities and undecidable, ill-posed sets of propositions. Constructivist content: The paper attempts to extend the scope of radical constructivist perspective to mathematical systems, and to discuss the relationships between radical constructivism and other allied, yet distinct perspectives in the debate over the foundations of mathematics, such as psychological constructivism and mathematical constructivism.

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.

In the reception of Josef Mitterer’s writings up to now, there are two predominant types of motifs: the radical constructivist background of his philosophy and the ontological and epistemological foundations and consequences of non-dualism. The critics are focused rather on some problematic consequences of non-dualism, ranging from the problem of infinite regress up to the thesis assuming that Mitterer’s philosophy presupposes a world reduced to descriptions. However, these two types of readings are founded on dualizing assumptions which are not coherent with non-dualism. \\Thus, in the present paper I interpret non-dualism in the frame of non-dual-ism, based on non-dualizing assumptions. I argue that non-dualism is a rhetorical project resulting in far-reaching consequences in the field of academic and scientific debates, poetics and practice of negotiations and deliberations, as well as in ordinary discourse. Non-dualism fulfills Richard Rorty’s dream of culture as a never-ending conversation in which the argument of power is successfully replaced by the power of argument. Mitterer makes transparent the rhetorical techniques performed in the dualizing discourse (not only in situations of conflict) in order to present an alternative – the non-dualizing mode of discourse. Mitterer’s philosophy – reread in the context of Rorty’s pragmatism, Foucault’s conception of discourses, Perelman’s new rhetoric – offers the new vocabulary (in Rorty’s meaning) which may change the practice of speaking

Key words: non-dualizing mode of speaking, description “so far” / “from now on, ” constructivism, rhetoric, discourse.

A case for a pluralistic approach to cognitive science is sketched. It is argued that cognitive scientists should take seriously the possibility that a single, unified framework for all of cognition is an unrealistic expectation for its diverse interdisciplinary goals and subject matter. A pluralistic approach instead seeks ways of integrating the multiple perspectives that have provided explanatory success in loosely interconnected sub-domains of cognitive phenomena. Research strategies recommended by this approach are discussed, with review of research currently carrying out such strategies and others that may hold promise for the future. The article ends with a discussion of seeking closer integration of the inquirer into consideration of which explanatory framework to choose. A systematic exploration of this transactional approach to cognitive science may grant coherence to pluralism even as it embraces diverse schemes of explanation.

Context: Non-dualist philosophy is no longer novel. Arguing against the distinctions between thought and action, theory and practice, language and objects has been a staple of the debate for decades, and Josef Mitterer offers another approach to the problem. Problem: Non-dualist philosophy is beset by a problem: it is trying to argue against a separation of “ideas” from the life-world while staying exclusively on the side of ideas. It offers a philosophy seminar argument against the bread and butter of philosophy seminars. Results: The paper argues that non-dualism in practice should be represented not by philosophers but by everyday life sociologists; not by those who argue against theory and idealisms but by those who simply ignore them. Non-dualism, however, is a useful tool when theorists have to be confronted practically; this, I argue, is its value, and in this debate, non-dualism is welcome. It is, however, a value that should not be overstated.

Key words: Non-dualism, pragmatism, everyday life sociology, symbolic interaction, Erving Goffman, Herbert Blumer

Clear statements of both extended and enactive conceptions of cognition can be found in John Dewey and other pragmatists. In this paper I’ll argue that we can find resources in the pragmatists to address two ongoing debates: (1) in contrast to recent disagreements between proponents of extended vs enactive cognition, pragmatism supports a more integrative view – an enactive conception of extended cognition, and (2) pragmatist views suggest ways to answer the main objections raised against extended and enactive conceptions – specifically objections focused on constitution versus causal factors, and the mark of the mental.

This paper focuses on one of the major contributions Heinz von Foerster has made to epistemology and the philosophy of science. It traces earlier disagreements with the traditional theory of knowledge and sketches the history to which von Foerster’s interpretation of the principle of indifferentiated coding supplied a decisive final chapter.
