This paper examines the shared roots and crossed paths between Jean Piaget’s constructivism, what Seymour Paper refers to as “constructionism,” and socio-cultural theories as epitomized by Lev Vygotsky. We do so in the light of more situated, pragmatic, and ecological approaches to human cognition. All these views are developmental (stressing the genesis children’s interests and abilities over time), experiential (in the sense that knowledge is rooted in sensori-motor activity) and interactionist (people are seen as constructing their knowledge by transforming the world). Yet, the views also differ, each highlighting some aspects of how children grow and learn, while leaving other questions unanswered. Piaget’s main contribution was to flesh out what is common in children’s ways of thinking at different stages of their cognitive development and, more important, how consistent, robust, and generally “adapted” their views are. The theory stresses the progressive de-contextualization of knowledge (from here-and-now to then-and-there) and identifies some of the hidden mechanisms (internal reorganizations) that drive human cognitive development. Papert, in contrast, stresses how individuals learn in context and how they use their own – and other people’s – externalizations as objects to think with, especially as their convictions break down. His approach is more situated. Papert is particularly interested the role of new media in human learning. Both Papert and Vygotsky shed light on the articulations between direct and mediated experience (from action and tool-use to enactments, language, and symbol-use). Yet Vygotsky and the Russian school have paid much closer attention to the role of caring adults and peers in a child’s initiation to her culture. They remind us that it takes a whole village to raise a child. Integrating the views helps rethink how children come to make sense of their experiences, and how they find their own places – and voices – in the world. At once world-makers, world-readers, and dwellers in the world, human infants are granted from birth with the abilities to optimize exchanges with people and things by moving in and out of contexts, by shifting perspectives, and by switching roles or standpoint. They are extraordinary learners, and much can be learned from them. Lastly, while mostly inner-driven and curious, children need caring adults, secure grounds, and engaging peers and props to thrive and grow. Tools, media, and cultural artifacts are the tangible forms through which they explore their surrounds, express their thoughts, and share the fun with others – and the traces left by those who came before (cultural heritage) become a terrain for newcomers to create their paths.

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 his comment, McGann argues that in my “From Sensorimotor Dependencies to Perceptual Practices: Making Enactivism Social,” I have overlooked a group of enactivist theories that can be grouped under the participatory sense-making label. In this reply, I explain that the omission is due to the fact that such theories are not accounts of perception. It is argued that, unlike participatory sense-making, the approach of the “From Sensorimotor Dependencies to Perceptual Practices” article does not focus on the perceptual aspects of things social, but on the social aspects that are constitutive of perception in general. I conclude by underscoring the central argument of the original article: that the adequate notion to make enactivism about perception social is that of “perceptual practices,” a social practices-based notion of perception.

This dissertation reconsiders the nature of scientific models through an historical study of the development of electronic models of the brain by Cybernetics researchers in the 1940s. By examining how these unique models were used in the brain sciences, it develops the concept of a “working model” for the brain sciences. Working models differ from theoretical models in that they are subject to manipulation and interactive experimentation, i.e., they are themselves objects of study and part of material culture. While these electronic brains are often disparaged by historians as toys and publicity stunts, I argue that they mediated between physiological theories of neurons and psychological theories of behavior so as to leverage their compelling material performances against the lack of observational data and sparse theoretical connections between neurology and psychology. I further argue that working models might be used by cognitive science to better understand how the brain develops performative representations of the world.

This paper aims at shedding light on what students can “construct” when they learn science and how this construction process may be supported. Constructivism is a pluralist theory of science education. As a consequence, I support, there are several points of view concerning this construction process. Firstly, I stress that constructivism is rooted in two fields, psychology of cognitive development and epistemology, which leads to two ways of describing the construction process: either as a process of enrichment and/or reorganization of the cognitive structures at the mental level, or as a process of building or development of models or theories at the symbolic level. Secondly, I argue that the usual distinction between “personal constructivism” (PC) and “social constructivism” (SC) originates in a difference of model of reference: the one of PC is Piaget’s description of “spontaneous” concepts, assumed to be constructed by students on their own when interacting with their material environment, the one of SC is Vygotsky’s description of scientific concepts, assumed to be introduced by the teacher by means of verbal communication. Thirdly, I support the idea that, within SC, there are in fact two trends: one, in line with Piaget’s work, demonstrates how cooperation among students affects the development of each individual’s cognitive structures; the other, in line with Vygotsky’s work, claims that students can understand and master new models only if they are introduced to the scientific culture by their teacher. Fourthly, I draw attention to the process of “problem construction” identified by some French authors. Finally, I advocate for an integrated approach in science education, taking into account all the facets of science learning and teaching mentioned above and emphasizing their differences as well as their interrelations. Some suggestions intended to improve the efficiency of science teaching are made.

The paper recalls some skeptical comments Norbert Wiener made regarding the potential use of cybernetics in social sciences. A few social scientists were seduced by cybernetics from the beginning, but cybernetics never really caught on in sociology. The paper argues that one reason for this may lie in the mathematical theory of communication entertained by early cybernetics. This theory which maintains that there are probability distributions of possible communication is at odds with the sociological theory’s idea of a communication driven by improbable understanding. Yet the move from first-order cybernetics to second-order cybernetics, by re-entering the observer into the very systems she observes, provides for a bridge between cybernetics and sociology.

Niklas Luhmann is not exactly known for his thinking about a possible change of the society due to the introduction of the computer. His society is the modern society, based on the overall importance of the communication medium of the printing press. Yet, his double volume book on Die Gesellschaft der Gesellschaft is so rich in remarks about the possible influence of the introduction of the computer on the society, equal only to the introduction of, first, writing and, then, the printing press, that one might be tempted to consider this book his way to bid farewell to the modern culture of the society based on the printing press. Let us look at what modern society has achieved relying on a notion of order stemming, with only slight exaggeration, from the library, and then let us try to watch how this very same society has to find equally wide-ranging solutions to a society relying, for a dominant part of its communication, on an order adapted to the computing machine, or so he seems to tell us. This paper looks at Die Gesellschaft der Gesellschaft in terms of a theory of the emerging computer culture of a society we cannot any more call the modern one. And it proposes to call for a competition to complete one of the most speculative chapters of this book in which Luhmann attributes the central cultural notion, or theory form, of the literal society, telos, to Aristotle, of the printing press society, self-referential restlessness, to Descartes, and leaves the slot open for the one possibly defining the culture of the computer society, which is the theory form of the form.

The paper looks at how a society having to deal with the introduction of the computer and its derivatives may differ from earlier societies which dealt with the introduction of language, writing, and the printing press. Each one of the introduction of these media of the dissemination of communication is regarded as a ‘catastrophe ’ forcing the society into new ways to selectively deal with new kinds of surplus meaning. The paper presents a sociological theory having to incorporate aspects of heterogeneous networks and of self-referential action in order to watch how the transformation of modern society into a next society may enfold. It draws a distinction between the structure of a society, ensuring the dissemination of communication, and the culture of the society, enabling it to condense the meaning of disseminated and distributed communication into a form which allows actors to focus on selections of it while taking account of the unmarked state as the other side of any one selection. Niklas Luhmann proposed to consider Aristotelian telos the ancient literal society’s culture form, and Cartesian self-referential restlessness or equilibrium as modern printing press society’s culture form. We add the culture form of boundaries for primitive oral society, and Spencer-Brownian form for the emerging next computer society. The paper will be

This is the second paper of a pair of two, the first one of which looked at a sociological theory of a computer-based future society distinct from earlier language-based ‘primitive’ society, writing-based ancient society, and printing press-based modern society. If the form of the next society’s culture will be the Spencer-Brownian form as we suggest, then sociological theory will have to reformulate itself in terms of an analysis of network synthesis. We look at possible reasons to do so, stemming above all from demands to be able to describe and understand how social actors are able to frame indeterminacy, present a possible model of social action, and advance the idea that it may be useful to base social analysis neither on subjects nor on objects but on a hypokeimon which we here propose to christen ‘catjects’. Catjects describe how a network synthesis comes about.
