A number of observations are made about the nature of constructivism, with the suggestion that it is a less revolutionary development that has been claimed, and that some accounts imply an unwarranted disregard of the environment. The presentation is meant to be provocative and to invite discussion that may clarify the issues.

Social Constructionism has been instrumental in remodeling grounded theory. In attempting to make sense of the social world, social constructionists view knowledge as constructed as opposed to created. This paper discusses how social constructionists construct knowledge and argues that social constructionism is concerned with the nature of knowledge and how it is created and as such, it is unconcerned with ontological issues. Society is viewed as existing both as a subjective and an objective reality. Meaning is shared, thereby constituting a taken-for-granted reality. Grounded theorists understand knowledge as beliefs in which people can have reasonable confidence; a common sense understanding and consensual notion as to what constitutes knowledge. If it is accepted that social constructionism is not based on a relativist perspective, then it is compatible with Grounded Theory methodology.

The key problem of cultural psychology comprises a paradox: while people believe they act on the basis of their own authentic experience, cultural psychologists observe their behavior to be socially patterned. It is argued that, in order to account for those patterns, cultural psychology should take human experience as its analytical starting point. Nevertheless, there is a tendency within cultural psychology to either neglect human experience, by focusing exclusively on discourse, or to consider the structure of this experience to originate in an already produced cultural order. For an alternative approach, we turn to the enactive view of cognition developed by Humberto Maturana and Francisco Varela. Their theory of autonomy can provide the epistemological basis for a cultural psychology that explains how experience can become socially patterned in the first place. Cultural life forms are then considered as consensually coordinated, embodied practices.

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.

Biosemiotics is the synthesis of biology and semiotics, and its main purpose is to show that semiosis is a fundamental component of life, i.e., that signs and meaning exist in all living systems. This idea started circulating in the 1960s and was proposed independently from enquires taking place at both ends of the Scala Naturae. At the molecular end it was expressed by Howard Pattee’s analysis of the genetic code, whereas at the human end it took the form of Thomas Sebeok’s investigation into the biological roots of culture. Other proposals appeared in the years that followed and gave origin to different theoretical frameworks, or different schools, of biosemiotics. They are: (1) the physical biosemiotics of Howard Pattee and its extension in Darwinian biosemiotics by Howard Pattee and by Terrence Deacon, (2) the zoosemiotics proposed by Thomas Sebeok and its extension in sign biosemiotics developed by Thomas Sebeok and by Jesper Hoffmeyer, (3) the code biosemiotics of Marcello Barbieri and (4) the hermeneutic biosemiotics of Anton Markoš. The differences that exist between the schools are a consequence of their different models of semiosis, but that is only the tip of the iceberg. In reality they go much deeper and concern the very nature of the new discipline. Is biosemiotics only a new way of looking at the known facts of biology or does it predict new facts? Does biosemiotics consist of testable hypotheses? Does it add anything to the history of life and to our understanding of evolution? These are the major issues of the young discipline, and the purpose of the present paper is to illustrate them by describing the origin and the historical development of its main schools.

This special issue invites a reflection on and reformulation of options for social construction as a theoretical and practical approach to studying communication as continuously emergent in relationships, constitutive of social reality, consequential to communicators, experienced through the bodily senses, and afforded by their material circumstances. Authors are encouraged to take stock of our predicted and actual accomplishments, consider the tensions between the promised and actualized changes brought about by social construction work in communication, and project the impact of social construction on the discipline in the next five to ten years. The focus is not only critical, but reflexive: How do we wish to reconstruct social construction? Relevance: The articles in the journal critically address social construction, taking on issues of its possibilities, shortcomings, and practical applications in psychotherapy, communication, and medicine.

This paper aims to characterize the “operative constructivism” of Niklas Luhmann from a comparison with two other streams of epistemological constructivism: Piaget-inspired constructivism and radical constructivism. This comparison focuses on three topics: the characterization of the active role of the epistemic subject; the problem of the status of knowledge and its relation to reality; and the problem of the origin of conceptual meaning and the individual-society relationship. Based on these characterizations, it is evaluated in what respects the constructivist program of Luhmann diverges or converges with the other two schools of epistemological constructivism.

Key words: operative constructivism, niklas luhmann, piaget’s constructivism, radical constructivism.

This paper analyzes Humberto Maturana’s understanding abour the objectivity of scientific knowledge through a critical dialogue with other contemporary epistemological constructivist theories. The two subjects discussed are the relations between knowledge-reality and knowledge-society, which are the most common senses that guide the philosophical discussion about objectivity. This paper also includes a systematization of the main theses of Matuana’s biology of cognition, and a brief evaluation of the role of the notion of “autopoiesis” for the understanding of objectivity.

Key words: autopoiesis, objectivity, constructivism, epistemology, humberto maturana.

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.
