Context: Society is faced with “wicked” problems of environmental sustainability, which are inherently multiperspectival, and there is a need for explicitly constructivist and perspectivist theories to address them. Problem: However, different constructivist theories construe the environment in different ways. The aim of this paper is to clarify the conceptions of environment in constructivist approaches, and thereby to assist the sciences of complex systems and complex environmental problems. Method: We describe the terms used for “the environment” in von Uexküll, Maturana & Varela, and Luhmann, and analyse how their conceptions of environment are connected to differences of perspective and observation. Results: We show the need to distinguish between inside and outside perspectives on the environment, and identify two very different and complementary logics of observation, the logic of distinction and the logic of representation, in the three constructivist theories. Implications: Luhmann’s theory of social systems can be a helpful perspective on the wicked environmental problems of society if we consider carefully the theory’s own blind spots: that it confines itself to systems of communication, and that it is based fully on the conception of observation as indication by means of distinction.

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.

In this part of our work about a comparison between Kelly’s personal construct theory and phenomenology, we enter the fields of psychotherapy and research. The topic of intersubjectivity, meant as original recognition of the other’s subjectivity, provides a backdrop for both phenomenological clinic and Kellyan psychotherapy. Though Kelly never used the term “intersubjectivity,” his theory and the corollary of sociality in particular, reveals a view of interpersonal relationships as intercorporeality, which is much closer to phenomenological ideas than to the cognitive ones. Depending on such commonality, in either cases clinical relationship is not viewed as an “aspecific factor” of psychotherapy, but as the essential tool for the care of other. Furthermore, the core role of intersubjectivity in scientific knowledge implies a radical revision of the criteria of research. Consistently with the intent of a science of experience, it is no more a matter of collecting data, as of accepting meanings. Psychological research has to refound itself in continuity with life and recognize the need for a real involvement and real interaction with the subjects, as far as to reverse the traditional relation between clinic and research. It is nonsense to conceive clinic as an applicative sector of a pure science because clinic, on the contrary, is the place where one can know, in first-person, those meaningful realities which take shape in the intersubjective exchange of ideas, in order to make them comprehensible and controllable. Relevance: The publication explores the dimension of intersubjectivity in phenomenology (starting from Husserl) and personal construct theory, and its relevance in psychotherapy and research.

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.

We characterize Rolando García’s view on science, as outlined on his writings on science and university policy, and then we trace this view on his constructivist epistemology. Through this lens, we analyze his review and reformulation of Jean Piaget’s constructivist theory, his subsequent reflection on interdisciplinary research of complex systems. Based on this analysis, we outline the current challenges for a constructivist epistemology.

When he formulated the program of neurophenomenology, Francisco Varela suggested a balanced methodological dissolution of the “hard problem” of consciousness. I show that his dissolution is a paradigm which imposes itself onto seemingly opposite views, including materialist approaches. I also point out that Varela’s revolutionary epistemological ideas are gaining wider acceptance as a side effect of a recent controversy between hermeneutists and eliminativists. Finally, I emphasize a structural parallel between the science of consciousness and the distinctive features of quantum mechanics. This parallel, together with the former convergences, point towards the common origin of the main puzzles of both quantum mechanics and the philosophy of mind: neglect of the constitutive blindspot of objective knowledge.

My purpose in this paper is to show that the transcendental approach, first formulated by Kant, and then elaborated by generations of neo-Kantian thinkers and phenomenologists, provides Buddhism in its highest intellectual achievement with a natural philosophy of science. I take this highest achievement to be the Madhyamaka dialectic and soteriology,{1} which was developed in India from the second century C.E. to the seventh century C.E. by masters such as Nāgārjuna, Āryadeva, and Candrakīrti. Relevance: This is an anti-realist interpretation of quantum mechanics related to the work of Francisco Varela.

Six arguments against the view that conscious experience derives from a material basis are presented, none of which is entirely new taken in isolation but whose conjunction is compelling. These arguments arise from epistemology, phenomenology, neuropsychology, and philosophy of quantum mechanics. It turns out that any attempt at proving that conscious experience is ontologically secondary to material objects both fails and brings out its methodological and existential primacy. No alternative metaphysical view is espoused (not even a variety of Spinoza’s attractive double-aspect theory). Instead, an alternative stance, inspired from F. Varela’s neurophenomenology is advocated. This unfamiliar stance involves (i) a complete redefinition of the boundary between unquestioned assumptions and relevant questions ; (ii) a descent towards the common ground of the statements of phenomenology and objective natural science: a practice motivated by the quest of an expanding circle of intersubjective agreement.
