This paper undertakes a theoretical investigation of the “learning” aspect of science as opposed to the “knowledge” aspect. The practical background of the paper is in agricultural systems research – an area of science that can be characterised as “systemic” because it is involved in the development of its own subject area, agriculture. And the practical purpose of the theoretical investigation is to contribute to a more adequate understanding of science in such areas, which can form a basis for developing and evaluating systemic research methods, and for determining appropriate criteria of scientific quality. Two main perspectives on science as a learning process are explored: research as the learning process of a cognitive system, and science as a social, communicational system. A simple model of a cognitive system is suggested, which integrates both semiotic and cybernetic aspects, as well as a model of self-reflective learning in research, which entails moving from an inside “actor” stance to an outside “observer” stance, and back. This leads to a view of scientific knowledge as inherently contextual and to the suggestion of reflexive objectivity and relevance as two related key criteria of good science.

The paradox of scientific expertise is that the growth of science leads to a fragmentation of scientific expertise. To resolve this paradox, this paper probes three hypotheses: 1) All scientific knowledge is perspectival. 2) The perspectival structure of science leads to specific forms of knowledge asymmetries. 3) Such perspectival knowledge asymmetries must be handled through second order perspectives. We substantiate these hypotheses on the basis of a perspectivist philosophy of science grounded in Peircean semiotics and autopoietic systems theory. Perspectivism is an important elaboration of constructivist approaches to help overcome problems in cross-disciplinary collaboration and use of science, and thereby make society better able to solve complex, real-world problems.

Context: The problems that are most in need of interdisciplinary collaboration are “wicked problems,” such as food crises, climate change mitigation, and sustainable development, with many relevant aspects, disagreement on what the problem is, and contradicting solutions. Such complex problems both require and challenge interdisciplinarity. Problem: The conventional methods of interdisciplinary research fall short in the case of wicked problems because they remain first-order science. Our aim is to present workable methods and research designs for doing second-order science in domains where there are many different scientific knowledges on any complex problem. Method: We synthesize and elaborate a framework for second-order science in interdisciplinary research based on a number of earlier publications, experiences from large interdisciplinary research projects, and a perspectivist theory of science. Results: The second-order polyocular framework for interdisciplinary research is characterized by five principles. Second-order science of interdisciplinary research must: 1. draw on the observations of first-order perspectives, 2. address a shared dynamical object, 3. establish a shared problem, 4. rely on first-order perspectives to see themselves as perspectives, and 5. be based on other rules than first-order research. Implications: The perspectivist insights of second-order science provide a new way of understanding interdisciplinary research that leads to new polyocular methods and research designs. It also points to more reflexive ways of dealing with scientific expertise in democratic processes. The main challenge is that this is a paradigmatic shift, which demands that the involved disciplines, at least to some degree, subscribe to a perspectivist view. Constructivist content: Our perspectivist approach to science is based on the second-order cybernetics and systems theories of von Foerster, Maruyama, Maturana & Varela, and Luhmann, coupled with embodied theories of cognition and semiotics as a general theory of meaning from von Uexküll and Peirce.

Key words: Perspectivism, semiotics, complex phenomena, social systems theory, differentiation of science, perspectival knowledge asymmetries.

Excerpt: Ecology is an eminently practical discipline, but the practical dilemmas of the ecological movement – and arguably of the environmental crisis itself – are the consequences of our failure to comprehend the complexity and unity of nature theoretically. The ecological crisis is first and foremost an epistemological crisis. 1 As Thomas Kuhn has taught us, such crises are potentially revolutionary episodes out of which new paradigms can emerge. 2 We have also learned from Kuhn that paradigm shifts are rarely sudden events; usually they unfold over decades or even centuries. So it has been with the search for a new paradigm that was inaugurated by Goethe’s scientific work. 3 As a practicing scientist and as a philosopher of science, Goethe both foresaw the crisis of mechanistic explanation and laid foundations for a new paradigm that might replace it. 4 In doing so, he also laid foundations for a future, alternative science of ecology. Although the term “ecology” did not exist until Ernst Haeckel coined it in 1866, Goethe was a profound ecologist in principle and practice if not yet in name. 5 This essay on four major “Goethean ecologists” seeks to add a brief chapter to the history of the reception of Goethe’s scientific work6 and also to Donald Worster’s now standard history of ecology, 7 which barely mentions Goethe in passing.

Constructivist ideas have had a major influence on science educators over the last decade. In this report a model describing possible student responses during science lessons is outlined, and a rationale for it is provided on the basis of both constructivist theory and tests of the model in middle school science classes. The study therefore explores a way to analyze and describe learning derived from both constructivist theoretical considerations and classroom practice. The model was tested in a series of science lessons, resulting in several revisions. The final version explained in this report is therefore consistent with the science lesson contexts explored and the theoretical constructs which underlie it. The lessons were conducted in three classes of 11- to 13-year-olds in provincial cities in Queensland, Australia. Students were mostly of Caucasian extraction, in mixed-ability and mixed-gender classes. Three students from each class were interviewed individually immediately following each of the three lessons, for a total of 27 interviews. The interviews, videotapes of lessons, and field notes were used as data sources. The final version of the model proved to be fairly robust in describing students’ cognitive progress through the lessons. This study has resulted in a model for science lessons which allows the identification and description of students’ cognitive progress through the lessons. By using this focus on the learner, it provides preknowledge for teachers about how students might arrive at solutions to science problems during lessons, and therefore potentially provides indications about appropriate teaching strategies.

While cognitive and social constructivism have at times been portrayed as competing paradigms, some authors such as Cobb (1994) have suggested that they are different ways of looking at the same thing. In an earlier paper, aspects of both cognitive and social constructivism were incorporated into a model used to analyse and describe student learning in science classrooms (Appleton, 1997). The model has subsequently been revised and has been used to draw implications for the teaching of science. In this paper, key elements of the model are explained, and how each may be used to inform and shape science teaching is explored.

For some years, there have been in‐service efforts to help teachers become familiar with constructivist ideas about learning, and to apply them in their science teaching. This study is a vignette of one teacher’s science teaching some time after such an in‐service activity. It explores the ways in which the teacher implemented his perceptions of constructivist ideas about learning in his teaching of a topic. The extent to which the teacher used teaching principles based on constructivism was influenced by his views of science and of learning, how he usually planned his teaching, and his confidence in his own understanding of the topic. Features of the teaching which reflect a constructivist view of learning are discussed and some problems are identified. We conclude with some reflections about in‐service programs within a constructivist framework.

While structured as an autobiography, this memoir exemplifies ways in which classic contributions to cybernetics (e.g., by Wiener, McCulloch & Pitts, and von Neumann) have fed into a diversity of current research areas, including the mathematical theory of systems and computation, artificial intelligence and robotics, computational neuroscience, linguistics, and cognitive science. The challenges of brain theory receive special emphasis. Action-oriented perception and schema theory complement neural network modeling in analyzing cerebral cortex, cerebellum, hippocampus, and basal ganglia. Comparative studies of frog, rat, monkey, ape and human not only deepen insights into the human brain but also ground an EvoDevoSocio view of “how the brain got language.” The rapprochement between neuroscience and architecture provides a recent challenge. The essay also assesses some of the social and theological implications of this broad perspective.

Analyzing the outline of the endless literature on consciousness, the separation between science and philosophy rather than being overcome, seems to come back in different shapes. According to this point of view, the hard problem seems to be how to study consciousness while avoiding a slip back to the old dualism. This article outlines the advantages of the phenomenological method. This method, more than getting over the mind-body separation, anticipates it through an open gaze, able to bring back the human presence as something structurally “ambiguous.” Reintroducing Husserl’s scientific project in a complete way, Francisco Varela opened up a research area yet to be explored, which promises to be fertile for neuroscience, provided that we accept that radicalism essential to 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.
