Excerpt: I wish address some of the paradoxes that arise if one adopts a non-critical radical constructivist stance to account for creative people’s interactions with – and through – (hu)man-made artifacts, in particular as they engage in the process of ‘world-making’, to use Goodman’s expression (1978), or designing in a broad sense.

The aim of this paper is to reconsider some of the stakes involved in the dialogue between sciences and between scientists, considering it as a complex and critical learning process. Dialogue – as conversation, expression, performance and negotiation – can be conceived in several ways. It carries both an epistemic and an experiential side. It involves simultaneously heterogeneous theories and identities. Because it involves fragmented scientific languages, it also requires a shared vision. But above all, what seems critical to acknowledge is that dialogue is a matter of transformation. And because transformation is also a matter of learning, the promotion of dialogue between sciences should be perceived as a virtuous spiral involving: instrumental learning (to dialogue), communicational learning (what we mean by dialoguing) and emancipatory learning (to challenge our core assumptions about dialogue and sciences). Considering the evolution of sciences as a double process embedded in the production of knowledge and the self-development of researchers raises the question of how to conceive simultaneously the relationships between these two major stakes. From a practical point of view, considering scientific dialogue as a lifelong learning process would finally suggest the management of forums like the World Knowledge Dialogue (WKD) as a privileged educational opportunity to be designed following what is known about science as a social practice and about researchers as adult learners. Based on the first edition of this forum, four suggestions are finally considered: favoring heterogeneity; valorizing formal knowledge as well as lived experience; acknowledging the learning dimension involved in the process of sharing; and confronting professional experience with knowledge produced about sciences. Inspired by Edgar Morin’s constructivist and non-dualistic position, this paper explores its practical stakes by revisiting the practice of transdisciplinary research and by considering the relationships between the process of knowledge construction and researchers’ self-development as a lifelong learning process.

Kelly’s personal construct theory, put forward in 1955, is considered the first constructivist theory of personality and the first expression of those contemporary psychotherapeutic perspectives grounded on a constructivist view of knowledge. Notwithstanding the similarities between psychological constructivism and the phenomenological-hermeneutic tradition, Kelly always rejected the parallel of his theory to phenomenology, regarding the latter as unacceptable since idealistic, solipsistic, and particularistic. In this first article of a work subdivided into three parts, the Authors explain such criticism by Kelly with his knowledge of phenomenology deriving from secondary sources, and stress the wide possibilities of a phenomenological interpretation and elaboration of his theory. Relevance: The publication highlights the analogy between psychological constructivism and phenomenology.

Enactivism is an emerging perspective both in cognitive science and in cultural psychology. Whereas the enactive approach in general has focused on sense-making as an embodied and situated activity, enactive cultural psychology emphasizes the expressive and dynamically enacted nature of cultural meaning. This chapter first situates enactivism within a tradition of expressivist thinking that has historical roots both in radical Enlightenment thought and Romantic reactions against the rationalization of human nature. It will then offer a view of our human biology that can be reconciled with an account of meaning as irreducibly normative. By emphasizing the consensual rather than the supposedly shared nature of meaningful conduct, enactivism avoids some of the classical pitfalls in thinking about culture. In the conclusion a genetic enactive psychology will be presented, which understands sense-making not as a mediated activity, but as a competence acquired through cultural training and personal stylization.

Key words: Enactivism, expression, consensual coordination, emotion, normativity, cultural training.

The course on nature coincides with the re-working of Merleau-Ponty’s breakthrough towards an ontology and therefore plays a primordial role. The appearance of an interrogation of nature is inscribed in the movement of thought that comes after the Phenomenology of Perception. What is at issue is to show that the ontological mode of the perceived object – not the unity of a positive sense but the unity of a style that shows through in filigree in the sensible aspects has a universal meaning, that the description of the perceived world can give way to a philosophy of perception and therefore to a theory of truth. The analysis of linguistic expression to which the philosophy of perception leads opens out onto a definition of meaning as institution, understood as what inaugurates an open series of expressive appropriations. It is this theory of institution that turns the analysis of the perceived in the direction of a reflection on nature: the perceived is no longer the originary in its difference from the derived but the natural in its difference from the instituted. Nature is the “non-constructed, non-instituted,” and thereby, the source of expression: “nature is what has a sense without this sense having been posited by thought.”\\The first part of the course, which consists in a historical overview, must not be considered as a mere introduction. In fact, the problem of nature is brought out into the open by means of the history of Western metaphysics, in which Descartes is the emblematic figure. The problem consists in the duality at once unsatisfactory and unsurpassable – between two approaches to nature: the one which accentuates its determinability and therefore its transparency to the understanding; the other which emphasizes the irreducible facticity of nature and tends therefore to valorize the viewpoint of the senses. To conceive nature is to constitute a concept of it that allows us to “take possession” of this duality, that is, to found the duality. The second part of the course attempts to develop this concept of nature by drawing upon the results of contemporary science. Thus a philosophy of nature is sketched that can be summarized in four propositions: 1) the totality is no less real than the parts; 2) there is a reality of the negative and therefore no alternative between being and nothingmess; 3) a natural event is not assigned to a unique spatio-temporal localization; and 4) there is generality only as generativity.

Context: Public universities in South Africa are currently facing the challenge of decolonising knowledge. This change requires a review of curriculums, as well as teaching and learning with the goal of embracing the epistemology of the learners, addressing issues such as social justice and transformation. Problem: Human communication is subject to several perceptual errors in both listening and seeing, which challenges the success of the communication in the education system. The ability of the teacher and the learners to effectively communicate with one another is a factor for the success of each reaching their goals. The teacher imparts her knowledge in the classroom, but according to von Foerster, “[i]t is the listener, not the speaker, who determines the meaning of an utterance,” for the listener contextualises this information based on her own past lived experience. Thus, the student’s epistemology and her expression of her understanding is integral in the classroom context and should be actively included into the education system. Method: I present a cybernetic approach to the teacher-learner system, challenging traditional ideas about the role of each actor within the system, with special attention given to Pask’s conversation theory. Results: Early empirical findings suggest that a conversational contextual approach results in higher student involvement and better memory retention among the learners. Conversational approaches that are epistemologically inclusive diffuse social problems where the student groups require their individual worldviews to be reflected within the curriculum. This reduces the friction of competing epistemologies within the education system, moving toward a co-created contextually-driven knowledge system. Implications: Many educators would like deeper engagement from their learners but have not found a way to successfully engage the student group. A cybernetic approach is one method that can be adopted to remedy this. This is particularly useful in contexts where there is cultural diversity and impending social change. Constructivist content: I address von Glasersfeld’s points on human cognition, linking it to Austin’s speech acts.

Key words: Contextual approach, conversation theory, decolonisation of knowledge, education, epistemology, teaching and learning.

In this article, the author provides a brief introduction to a completely new theory in Semantics, Operational Semantics (OS), which concerns the meaning of the basic linguistic elements that are indispensable for any linguistic expression, i.e., the fundamental “grammatical” words and morphemes. Even if in the text there is no explicit reference to constructivism, OS could be relevant for constructivist approaches, since its fundamental presupposition is that the meanings of these linguistic elements are mainly sequences of elemental mental operations (amongst which those of attention play a key role) that are actively carried out by the subject.

An approach which has the purpose to catch what characterizes the specificity of a living system, pointing out what makes it different with respect to physical and artificial systems, needs to find a new point of view – new descriptive modalities. In particular it needs to be able to describe not only the single processes which can be observed in an organism, but what integrates them in a unitary system. In order to do so, it is necessary to consider a higher level of description which takes into consideration the relations between these processes, that is the organization rather than the structure of the system. Once on this level of analysis we can focus on an abstract relational order that does not belong to the individual components and does not show itself as a pattern, but is realized and maintained in the continuous flux of processes of transformation of the constituents. Using Tibor Ganti’s words we call it “Order in the Nothing”. In order to explain this approach we analyse the historical path that generated the distinction between organization and structure and produced its most mature theoretical expression in the autopoietic biology of Humberto Maturana and Francisco Varela. We then briefly analyse Robert Rosen’s (M, R)-Systems, a formal model conceptually built with the aim to catch the organization of living beings, and which can be considered coherent with the autopoietic theory. In conclusion we will propose some remarks on these relational descriptions, pointing out their limits and their possible developments with respect to the structural thermodynamical description.

Key words: Autonomy, Autopoiesis, (M, R)-Systems, Organization, Relational Biology

Attempting to capture the complexity of learning on standardized state assessments severely limits student knowledge and expression. Inevitably, schools reduce the curriculum to what is covered on tests. Students control their learning. Constructivist teachers structure lessons around big ideas, value relevance, and strive to challenge students’ suppositions.

Open peer commentary on the article “A Critique of Barbieri’s Code Biology” by Alexander V. Kravchenko. Abstract: My commentary criticizes Kravchenko’s objections to Barbieri’s biosemiotic theory. Because Kravchenko holds that concepts of signs, codes, and languages should be applied only to humans, his position, which is neither clearly explained nor defended, completely rules out any semiotics that would apply to biological construction in organisms (genetic codes and their expression), intra-organismic communication processes (molecular signals and their interpretations), informational processes in nervous systems (neural codes and how they are read out), and animal communication. I argue that most of the critique is about unproductive disagreements over word usages rather than an attempt to develop an alternative biosemiotics. Kravchenko’s critique also misconstrues how biosemioticians think about signs, codes, interpretation, meaning, and epistemology.
