Chapter Growing up Constructivist: Languages and Thoughtful People What is radical constructivism? It is an unconventional approach to the problems of ...

Motivation: Paralleling my own transformation from a Platonist to a radical constructivist, mathematics education has been experiencing for more than a decade a movement that started in theoretical foundations mostly originating in von Glasersfeld's work, and then reached professional organizations, which have been leading extensive efforts to reform school mathematics according to constructivist principles. However, the theories espoused by the researchers are, as yet, too abstract to lend themselves readily to implementation in the classroom. N2 - Purpose: I define (...) a shared experiential language (SEL) for the constructivist teacher to embody in order to transform her practice congruently according to constructivist principles. While SEL is comprised of Neuro-Linguistic Programming (NLP) subjective experience distinctions, what "makes it tick" is the constructivist epistemology with its insight that for consistent understanding to happen, new knowledge has to attach to prior experiences in a process of co-construction. Throughout the paper, I elaborate and validate this insight by numerous examples. Practical implications: Utilizing SEL allows understanding of mathematics to be rooted in each student's individual sensory experiences, thus shifting the responsibility for success in mathematics from the students back to those who guide them in co-constructing knowledge. This, in turn, should allow everybody access to understanding and so it should no longer be socially acceptable to fail in mathematics. (shrink)

This chapter contains section titled: Ontology of Radical Construction Arguments for Radical Constructivism Can Radical Constructivism Be Refuted? Notes.

Context: The main problem is the rather marginal status of radical constructivism within its core domains of brain research, cognition and learning. Problem: The basic goal is to provide a short history of radical constructivism and its institutionalization processes. Additionally, the article specifies critical conditions that should be met in order for radical constructivism to become a mainstream endeavor. Method: The main methods used are those of comparative historical research. Results: The main results lie (...) in the specification of missing elements that have blocked radical constructivism becoming a mainstream endeavor. Implications: The paper might serve as a common reference for necessary steps to be taken over the following years in order to move radical constructivism out of its current weak position. (shrink)

Purpose: Describing how radical constructivism was introduced to communication science and analyzing why it has not yet become a mainstream endeavour. Situation: Before radical constructivism entered the relevant debates in communication sciences, moderate constructivist positions had already been developed. Problem: Radical constructivists’ argumentation has often been provocative and exaggerating in style, and extreme in its position. This has provoked harsh reactions within the mainstream scientific community. Several argumentative strategies have been used to degrade radical (...) constructivist arguments and their relevance. Solution: Beyond such rhetorical devices, radical constructivism has become established within the field of communication science, although it has not become mainstream. One should probably not even wish to make radical constructivism a mainstream approach in case it loses its sceptical ability for second-order-observation. (shrink)

From the constructivist perspective, science cannot transcend thedomain of experience. Scientific theories are seen as models that helpto order and manage that domain. As the experiential field expands,models are replaced by others based on novel conceptual constructs. Thepaper suggests the substitution of viability or functional fit forthe notions of Truth and objective representation of anexperiencer-independent reality. This by-passes the sceptics'incontrovertible arguments against certain real-world knowledge andproposes the Piagetian conception of cognition as the function thatgenerates ways and means for dealing with (...) the world of experience.

Context: The current situation in philosophy of science includes central, ongoing debates about realism and anti-realism. The same question has been central to the theorising of radical constructivism and, in particular, to its implications for educational theory. However the constructivist literature does not make significant contact with the most important, mainstream philosophical discussions. Problem: Despite its overwhelming influence among educationalists, I suggest that the “radical constructivism” of Ernst Glasersfeld is an example of fashionable but thoroughly problematic (...) doctrines that can have little benefit for practical pedagogy or teacher education. My critique has a positive goal: it is important to understand why constructivism has generated such severe polarization and disputation. A symptom of the problem is the concern with the most abstruse and obdurate problems of philosophy that have no conceivable bearing on educational practice or anything else, for that matter. The diagnosis is confirmed by those pedagogical recommendations that are allegedly derived from radical constructivism that are touted as revolutionary but are platitudes of common sense. I suggest that, ironically, this observation itself provides some pedagogical insight. Method: The approach adopted for the topic is critical, philosophical analysis of the various claims and theses of radical constructivism in the light of philosophy of science and psychology. Results: The findings of the paper are that central theoretical claims of constructivism are couched in an unclear and unnecessary jargon that obscures the implausibility or banality of these claims. Implications: The value of the paper lies in providing an analysis and critique of central, influential claims of radical constructivism both in relation to issues in epistemology and also in relation to the alleged bearing of these claims on pedagogy. It is suggested that, contrary to the claims of radical constructivists, there are few if any implications for practice and applications. (shrink)

Radical constructivism has had a major influence on present-day education, especially in the teaching of science and mathematics. The article provides an epistemological profile of constructivism and considers its strengths and weaknesses from the standpoint of its educational implications. It is argued that there are two central problems with constructivism: anti-realism and individualism which, in turn, lead to difficulties associated with idealism and relativism which, together, prove fatal for the theory.

the editor and publisher are to be commended on the publication of this book. It will, in all probability, not be able to resolve the controversies surrounding radical constructivism but it will serve as a standard reference to the theory of radical constructivism, as advocated by its originator and leading figure, Ernst von Glasersfeld. It is hereby strongly recommended.

This article addresses the issue of objectivism vs constructivism in two areas,biology and cognitive science, which areintermediate between the natural sciences suchas physics (where objectivism is dominant) andthe human and social sciences (whereconstructivism is widespread). The issues inbiology and in cognitive science are intimatelyrelated; in each of these twin areas, the objectivism vs constructivism issue isinterestingly and rather evenly balanced; as aresult, this issue engenders two contrastingparadigms, each of which has substantialspecific scientific content. The neo-Darwinianparadigm in biology is (...) closely resonant withthe classical cognitivist paradigm in cognitivescience, and both of them are intrinsicallyobjectivist. The organismic paradigm inbiology, based on the concept of autopoiesis,is consonant with the paradigm of enaction incognitive science; the latter paradigms are bothprofoundly constructivist.In cognitive science, the objectivism vsconstructivism issue is internal to thescientific field itself and reflexivity isinescapable. At this level, strong ontologicalobjectivism is self-contradictory and thereforeuntenable. Radical constructivism isself-coherent; but it also rehabilitatesa weak form of objectivism as a pragmaticallyviable alternative. In conclusion, there is aneven-handed reciprocity between objectivistand constructivist perspectives. Finally, thearticle examines the consequences of thisconclusion for fields other than cognitivescience: biology; physics and the naturalsciences; and the human and social sciences. (shrink)

Purpose: This paper intends to connect ideas from the radical constructivist approach to cognition and learning to ideas from the constraint-theoretic approach to social policy formulation. It then extends these ideas to a dialogic approach to social transformation and design. Method: After demonstrating a correspondence between von Glasersfeld's fit/match distinction and my constraint-oriented/goal-oriented distinction with respect to policy formulation, the paper evaluates the basic assumptions of radical constructivism and builds from them a framework for thinking and talking (...) about a desirable society and ways to participate in its realization. Findings: The ideas of von Glasersfeld's radical constructivism contribute significantly to the development of a conceptual base for applied research on social activism by raising new questions and stimulating new thinking. Practical implications: Social activism in everyday affairs can be a way of living in the "world." Conclusion: The work and thought of Ernst von Glasersfeld opens a path toward a rich array of concepts and ideas with the potential to inform efforts in a wide variety of human endeavors. (shrink)

Context: Using radical constructivism, society can be considered from the perspective of asking the question, “Who conceives of society?” In Luhmann ’s social systems theory, this question itself is considered as a construct of the communication among reflexive agents. Problem: Structuration of expectations by codes operating in interhuman communications positions both communicators and communications in a multi-dimensional space in which their relations can be provided with meaning at the supra-individual level. The codes can be functionally different and symbolically (...) generalized. Method: More than Luhmann, I focus on the hypothetical status of the communication of meaning and the uncertainty involved. Meaning can be communicated because of reflexivity in interhuman communications; meaning cannot be observed. Results: The communication of denotations between semantic domains can generate “horizons of meaning” as reflexive orders that remain structurally coupled to individual minds. This elusive order contains a trade-off between “organization” at interfaces integrating expectations at each moment of time, and the potential of further differentiation among symbolically generalized codes of communication in a “self-organization” over time. Implications: One can model the coding in the communication of meaning as latent variables that evolve as an implication of the interacting intentions and expectations. The structure of expectations can be visualized and animated using semantic maps. The self-organizing horizons of meaning operate in a multidimensional space different from the network topology, and at another pace, since meaning is provided to events from the perspective of hindsight. Constructivist content: This perspective of the radical constructedness of social reality transforms the status of agency and organization in sociological theorizing from a source of change to a resource of communicative competencies and reflexive performativity.

Purpose: Several accounts like Ernst von Glasersfeld's Who Conceives of Society? (2008) locate empirical research in the social sciences and radical constructivism in almost parallel universes. The main purpose of this paper is to argue for more inter-active relations and to stress the importance of establishing weak, medium and strong ties between radical constructivism and empirical social research in general. Findings: The article shows that that weak, medium and strong ties between radical constructivism and (...) empirical research in the social sciences can be established. Moreover, these weak, medium and strong ties play a crucial role for increasing and maintaining the relevance of radical constructivism within the social sciences and for contributing to the viability of radical constructivism in the long run. Implications: The most important consequence for radical constructivism lies in a new research agenda. In the course of this article weak, medium and strong ties to empirical research have been specified specifically and exclusively for the social sciences. But these specific links cannot be simply generalized or transferred to other disciplinary fields outside the social sciences. Since interactive links between radical constructivism and empirical research are currently missing in practically all disciplines, these weak, medium and strong links, as a new RC-agenda, have to be developed separately for each major scientific research arena.

Theology and religious beliefs, including issues dealing with theism, deism, creedal statements, dogma, and spiritualism are considered to be constructed reality. They are herein identified as first order truth. First order truth is personal truth and, as such, it becomes part of the reality of the believer. Constructed theological and religious belief is considered to be a legitimate part of radical constructivism irrespective of the validity and viability of the constructed reality. Second order truth, truth that is beyond (...) the limits of human verification, is herein introduced as the term for ultimate ontological and metaphysical reality. As such, reality is neither denied nor is it attributed to a solipsistic mind. Ultimate and so-called metaphysical reality is unknowable in the epistemological sense of having the capability of being known in any empirical and verifiable manner. To the degree that ultimate and metaphysical reality is known, it is known only via the constructs of the human mind. Perceptions of reality that arise from rigorous empirical research, including experimental and observational data, are certainly to be considered valid, reliable, and viable, but never irreplaceable. In the practice of science and the scientific method there is always the possibility of new hypotheses and theories based on new experimentation and new data, and thus, a case may be made that all knowledge, even scientific and empirical knowledge, is tentative.

Context: In spite of its advantages and its ability to make valid responses to objections, radical constructivism is not mainstream. Problem: Extolling the virtues of radical constructivism and responding logically to the objections does not work. We know this from the evidence of many attempts. Our theoretical stance, radical constructivism, also suggests this approach is not likely to have much influence on realists. We cannot transmit understanding in the signals with which we attempt to (...) communicate. How can we in radical constructivism enable those outside of RC to understand our explanation of human knowing? Method: Examine our understanding of radical constructivism itself, because it is an explanation of how, why and under what circumstances people change their understandings of their experiential worlds. Results: We must find ways to direct the attention of others to situations that they cannot explain with their existing understanding of the world. Then we must create conditions conducive to their revising and testing new understandings for fit with the evidence of their experience. Implications: Since radical constructivism is a theory of human knowing, it tells us how humans develop knowledge, hence it is an answer to the questions central to this special issue. This answer is not one to be used to win in debates with realists. Radical constructivism gives us an answer to the problem of engaging realists in understanding our position, but strategies consistent with radical constructivism are not easily carried out. Developing and executing such strategies is the work at hand. (shrink)

Context: Structural design education in architecture is typically conceived as a scientific subject taught in a lecture format and based on a transactional view of learning. This approach misses opportunities to contribute to and integrate with design-studio-based architectural education. Problem: How can radical constructivism inform a design-based pedagogy of structural design in the context of large cohorts of Chinese learners? Method: The paper outlines how radical constructivist and second order cybernetic perspectives are reflected in an alternative educational (...) approach to structural design. This approach encourages students’ individual learning while negotiating constraints deriving from large cohorts as well as the educational expectations of Chinese learners. Results: Teaching outcomes as well as students’ comments show successes in engaging students in adopting a more personal and active attitude in their learning. Students appreciate and praise learning grounded in experience as well as collaborative, peer-led learning. Challenges remain in establishing a more dialogical learning situation and in supporting individual students’ learning in large student cohorts. Implications: Limitations arise from the constraints imposed by large cohorts, limited manpower and an institutional preference for teaching towards written examinations. The research and teaching development presented are ongoing. This paper may inform educators in the fields of architecture and engineering as well as, more generally, educators who seek to develop their teaching based on a radical constructivist epistemology in the context of large cohorts. Constructivist content: The teaching approach presented links a radical constructivist perspective based on Ernst von Glasersfeld’s work with second-order cybernetics in the context of design-based education. The paper discusses challenges and opportunities for this approach in the context of large cohorts of Chinese learners. (shrink)

Context: It is beyond doubt that RC has received a great deal of attention in educational studies and learning theory. But overall, the current situation seems to be rather ambivalent in view of the blurring of the various strands in constructivist discourses and the different ways of distinguishing and foregrounding constructivist positions. Correspondingly, there is a wide range of claims, from the claim that (radical) constructivism represents a mainstream endeavor to attributions of its being outdated, self-refuting or irrelevant. (...) Purpose: The paper seeks to sound out the ambivalent situation of (radical) constructivism between “all” and “nothing” by examples of attributions of meaning to constructivist positions in academic everyday life and by challenging both prevalent criticisms of systemic-constructivist pedagogy and widespread broad classifications in learning theory. Method: The article critically reflects on (1) one-sentence “destructions” of constructivist positions, (2) Pongratz’s criticism of systemic-constructivist pedagogy, and (3) the threefold classification of the world of learning, i.e., behaviorism, cognitivism, and constructivism. Results: Both the current criticism of constructivism as a mainstream endeavor and evolutionary suggestions provided by the threefold classification are criticized. Although some constructivist concepts and distinctions are widely accepted today, often these achievements are not recognized as being rooted in constructivist discourses. Implications: As far as mainstreaming constructivism might be related to power politics, selling the “real thing,” and joining the ranks of truth-oriented Isms, it would not appear to be a desirable endeavor for those who rely on viability, circular foundations, relativist philosophy, and relationalist approaches. Nevertheless, clarifications of power relations and the interplay between constructivist analyses of politics and the politics of constructivism might contribute to overcoming the diffuse popularity of constructivist thought towards a better understanding of constructivist contributions to solution oriented, meaningful ways of dealing with urgent problems.

As a technology and an art form perceived to be capable of reproducing the world, it has long been thought that the cinema has a natural affinity with reality. In this essay I consider the Realist theory of film history out forward by Robert C. Allen and Douglas Gomery from the perspective of Radical Constructivism. I argue that such a Realist theory cannot provide us with a viable approach to film history as it presents a flawed description of (...) the historian’s relationship to the past. Radical Constructivism offers an alternative model, which requires historians to rethink the nature of facts, the processes involved in constructing historical knowledge, and its relation to the past. Historical poetics, in the light of Radical Constructivism, is a basic model of research into cinema that uses concepts to construct theoretical statements in order to explain the nature, development, and effects of cinematic phenomena.

Purpose: The paper intends to investigate possible affinities between Husserlian phenomenology, mainly on the basis of Zur Phänomenologie der Intersubjektivität, and radical constructivism, essentially in its version according to Maturana and Varela. Findings: Although the two thoughts appear to be delivered in terms that can be philosophically quite abstract for the Husserlian phenomenology and that are empirical-concrete for radical constructivism in Maturana's thought, there is actually an obvious closeness between the two theories of knowledge, so that (...) the epistemological approach used on both sides can be said to be idealistic. This idealistic orientation in epistemology certainly has its basis in the links seen on both sides between the organic and the cognitive dimension of the subject, although those links are taken as a theme in a kinesthetic approach by Husserl and in a bio-physiological one by Maturana. Neurophenomenology is nowadays one of the fields where this organic--cognitive link -- which is crucial for an idealistic approach to knowledge -- is being expressed. Research implications: Talking about idealism should not be a source of fear, especially when what is meant is an epistemological idealism and when it is clearly and simply understood as the philosophical and epistemological orientation that interprets the subject as determining the way the object is known in the cognitive process. Also idealism does not mean necessarily subjective idealism. Some very "balanced" authors developed a theory of knowledge that is usually seen as idealistic without ignoring the role played by the object in the cognitive process. It is therefore worth investigating further the fact that the ultimate meaning of idealistic epistemologies acknowledging intersubjectivity as a defining dimension of knowledge, is not to ignore the object but to rigorously reestablish the genesis of the object in the cognitive process.

Open peer commentary on the article “Constructing Constructivism” by Hugh Gash. Upshot: Radical constructivism is explicitly discussed in Gash’s target article outlining “stages” or types of constructivism. The stages contextualize radical constructivism in a series of research phases involving a number of domains using a variety of approaches. The target article begs the query: “just how radical are many constructivist approaches in teaching and learning?”.

Purpose: In the paper, I discuss how Ernst Glasersfeld worked as a scientist on the project, Interdisciplinary Research on Number (IRON), and explain how his scientific activity fueled his development of radical constructivism. I also present IRON as a progressive research program in radical constructivism and suggest the essential components of such programs. Findings: The basic problem of Glasersfeld's radical constructivism is to explore the operations by means of which we assemble our experiential reality. (...) Conceptual analysis is Glasersfeld's way of doing science and he used it in IRON to analyze the units that young children create and count in the activity of counting. In his work in IRON, Glasersfeld first conducted a first-order conceptual analysis of his own operations that produce units and number, and then participated in a second-order analysis of the language and actions of children and inferred the mental operations that they use to produce units and number. Further, Glasersfeld used Piaget's concept of equilibration in the context of scheme theory in a second-order analysis of children's construction of number sequences and of more advanced ways and means of operating in the traffic of numbers. Research Implications: The scientific method of first- and second-order conceptual analysis transcends our work in IRON and it is applicable in any radical constructivist research program whose problem is to explore the operations by means of which we construct our conceptions. Because of the difficulties involved with introspection, conducting second-order conceptual analyses is essential in exploring these operations and it involves analyzing the language and actions of the observed. But conceptual analysis is only a part of the research process because the researchers are by necessity already involved in creating occasions of observation. The "experimenter" and the "analyst" can be the same person or they can be different people. Either case involves intensive and sustained interdisciplinary thinking and ways of working if the research program is to be maintained over a substantial period of time as a progressive research program.

Problem: An answer to the question of whether or not Radical Constructivism RC can or will become a mainstream endeavour is difficult, because what is called RC is a bundle of quite divergent approaches and not a homogenous (super) theory. Therefore the article concentrates upon “classical” RC as developed first of all by von Glasersfeld, von Foerster and Maturana and Varela. The pros and cons of their approaches are discussed and evaluated. Solution: In order to overcome the most (...) obvious problems of RC, a strict process-oriented kind of argumentation is developed that replaces is/is not assertions with descriptions of processes and their results, thus answering the question of what might reasonably be called “construction.” Benefit: The paper presents a way of rewriting RC, i.e., avoiding its evident problems, without abandoning the insights that RC thinkers have gained in the past.

Open peer commentary on the target article “From Objects to Processes: A Proposal to Rewrite Radical Constructivism” by Siegfried J. Schmidt. Upshot: I focus my commentary on the fundamental metaphysical issue that Siegfried J. Schmidt’s very stimulating paper addresses in §45 and particularly upon the relationship between the ontological status of the processes from which worlds emerge and the temporality of the objects to be found therein. I argue that Schmidt’s emphasis on world-forming processes raises many questions concerning (...) the temporal stability of objects and the relationship between objects and actors belonging to different worlds. I suggest that some classic as well as contemporary thinkers (e.g., Fichte, Hegel, Heidegger, Gadamer, Foucault, and S. J. Gould) have faced similar problems and discuss how their answers could be integrated within Schmidt’s revised radical constructivism. (shrink)

Open peer commentary on the article “Ethics: A Radical-constructivist Approach” by Andreas Quale. Upshot: Andreas Quale in his article defends radical constructivism (RC) from the accusation of being guilty of being ethically neutral. His defence is based on a distinction between clearly communicable cognitive knowledge and less easily communicable value-laden non-cognitive knowledge. The position taken in this commentary is that RC is a process and provides a way of understanding values. To condemn RC for ethical neutrality is (...) to confuse process and product. (shrink)

Excerpt: The difference between realism and constructivism is reduced from an epistemological distinction to merely a difference in (epistemological) attitude... Both modes of thinking -- the realist just like the constructivist -- are manifestations of an argumentation technique.

Open peer commentary on the article “Constructing Constructivism” by Hugh Gash. Upshot: Gash describes some very interesting and exemplary work using RC-influenced research and practices. I worry that his third stage of a three-stage emergence of constructivist epistemology in the study of cognitive development is consistent with a distinction between focus on individual cognitive development and focus on knowledge not in the mind but in the group, inconsistent with RC. An alternative is given and the issue of an RC (...) perspective on social justice is discussed. (shrink)

Open peer commentary on the article “Constructing Constructivism” by Hugh Gash. Upshot: Gash’s retrospective analysis suggests a number of different roles for RC over the past thirty years. We outline three of these roles and then conduct a thought experiment to argue that while RC itself could be seen as a living theory that accommodates new ideas, its strongest contributions remain when it stays true to its roots and serves as a milestone along the path of educational paradigm shifts.

In this work I try to show that radical, epistemological constructivism is an untenable thesis. Not so much because the arguments in favor of such a thesis are deficient, but because there are crucial problems that no constructivist seems to have solved and that must be solved in order for it to be possible to even formulate the thesis in question. I also mention a consequence that these considerations have in education. En este trabajo intento mostrar que el (...) constructivismo epistemológico radical es un tesis insostenible, no tanto porque los argumentos a favor de dicha tesis sean deficientes sino porque hasta ahora existen problemas cruciales que ningún constructivista parece haber resuelto y que, sin embargo, deben ser resueltos para poder siquiera formular la tesis en cuestión. También me refiero a una consecuencia que estas consideraciones tienen en educación. (shrink)

Constructivism is the idea that we construct our own world rather than it being determined by an outside reality. Its most consistent form, Radical Constructivism (RC), claims that we cannot transcend our experiences. Thus it doesn't make sense to say that our constructions gradually approach the structure of an external reality. The mind is necessarily an epistemological solipsist, in contrast to being an ontological solipsist who maintains that this is all there is, namely a single mind within (...) which the only world exists. RC recognizes the impossibility of the claim that the world does not exist. Yet, RC has the potential to go much further. I claim that RC provides the foundation of a new world-view in which we can overcome hard scientific problems. Thus, the paper is urging us to carry RC further, not just on philosophical grounds, but also into the domain of science. (shrink)

Problem: The paper investigates some reasons why RC has not become a mainstream endeavor. Method: The central assumptions of RC are summarized. Analysis is made of how each of these assumptions corresponds to other views, especially to intuitive beliefs that are widely accepted. Is RC consistent with these beliefs, supported by them, or incompatible with them? Results: The construction hypothesis is supported by the results of cognitive science and neurophysiology. However, the closed-system hypothesis and antirealism are in conflict with deeply (...) rooted convictions of most people. Some ethical and educational aspects claimed by RC are generally accepted but they are not specifically implications of RC. Implications: In the near future, RC will probably not become the leading paradigm or a mainstream endeavor in the sciences or in philosophy. (shrink)

Context: The theory of radical constructivism offers a tool for the evaluation of knowledge in general: especially with regard to its epistemic and ontological character. This applies in particular to knowledge that is non-cognitive, such as, e.g., ethical convictions. Problem: What impact can radical constructivism have on the topic of ethics? Specifically, how can ethical issues be resolved within a radical-constructivist epistemic approach? Method: I extend the theory of radical constructivism to include also (...) items of non-cognitive knowledge. This makes it possible to discuss ethical issues, which are non-cognitive, in a constructivist epistemic and ontological perspective. Some arguments against this conception of “strictly personal ethics” are discussed. Results: Radical constructivism is neutral on ethical issues, and thus cannot be invoked to endorse any particular ethical position. However, this causes no problem for the theory: the individual knower will construct her own ethical values and convictions, as part of her store of non-cognitive knowledge, in interaction with her environment (including other individuals. Hence ethical values cannot be argued in cognitive terms; and this elevates the knower into a position of personal responsibility with respect to ethical issues. Constructivist content: I focus on the role played by radical constructivism in the approach to cognitive vs. non-cognitive knowledge. The construction of knowledge (of any kind) emerges as a strictly personal enterprise. For instance, in the context addressed here, constructed non-cognitive knowledge forms a basis for the individual knower’s ethical position. (shrink)

Context: In the literature of radical constructivism, the epistemology and ontology of religion has been rarely discussed. Problem: I investigate the impact of radical constructivism on some aspects of religion - in particular, on the conflict that is sometimes perceived to arise between religion and natural science, discussed in the context of religious belief. Method: It is argued that the epistemology of radical constructivism serves to distinguish between items of cognitive and non-cognitive knowledge. This (...) makes it possible to discuss issues of religious belief, which are non-cognitive, from a constructivist epistemic and ontological perspective. Results: I conclude that radical constructivism cannot be invoked to support or contradict any particular religious faith; the individual knower will construct her own ontology, as part of her store of non-cognitive knowledge, in interaction with her environment ; on the other hand, any knowledge of it must be constructed in the mind of the knower, and there is no way to identify any one construction as being objectively “right” or “true.” Hence the truth value of propositions of religious conviction cannot be argued in cognitive terms. Implications: It is argued that these results elevate the knower into a position of personal autonomy with respect to religious issues. One consequence of this is the emergence of a fundamental epistemic incompatibility between the worldviews of radical constructivism and religion of any kind. Another is that the old dichotomy between atheism and agnosticism disappears - or rather, becomes irrelevant. Constructivist content: The role played by radical constructivism in the approach to cognitive vs. non-cognitive knowledge is discussed, specifically as pertaining to issues of religion. The construction of knowledge is a strictly personal enterprise, and the use of constructed non-cognitive knowledge then forms a basis for the individual knower’s religious position. (shrink)

Problem: How can radical constructivism gain wider recognition and acceptance? Method: Based on informal direct observation of other social and intellectual movements, the social and psychological dynamics and organizational imperatives of radical constructivism as an intellectual movement are discussed. Results: Various means of structuring the movement in order to gain wider acceptance are proposed. Implications: We hope that the paper has value in helping the radical constructivism movement evaluate where it has been and where (...) it might go in terms of wider social recognition and acceptance. (shrink)

Problem: There is currently a great deal of mysticism, uncritical hype, and blind adulation of imaginary mathematical and physical entities in popular culture. We seek to explore what a radical constructivist perspective on mathematical entities might entail, and to draw out the implications of this perspective for how we think about the nature of mathematical entities. Method: Conceptual analysis. Results: If we want to avoid the introduction of entities that are ill-defined and inaccessible to verification, then formal systems need (...) to avoid introduction of potential and actual infinities. If decidability and consistency are desired, keep formal systems finite. Infinity is a useful heuristic concept, but has no place in proof theory. Implications: We attempt to debunk many of the mysticisms and uncritical adulations of Gödelian arguments and to ground mathematical foundations in intersubjectively verifiable operations of limited observers. We hope that these insights will be useful to anyone trying to make sense of claims about the nature of formal systems. If we return to the notion of formal systems as concrete, finite systems, then we can be clear about the nature of computations that can be physically realized. In practical terms, the answer is not to proscribe notions of the infinite, but to recognize that these concepts have a different status with respect to their verifiability. We need to demarcate clearly the realm of free creation and imagination, where platonic entities are useful heuristic devices, and the realm of verification, testing, and proof, where infinities introduce ill-defined entities that create ambiguities and undecidable, ill-posed sets of propositions. Constructivist content: The paper attempts to extend the scope of radical constructivist perspective to mathematical systems, and to discuss the relationships between radical constructivism and other allied, yet distinct perspectives in the debate over the foundations of mathematics, such as psychological constructivism and mathematical constructivism. (shrink)

Context: A number of objections that are frequently raised in the literature against radical constructivism, including: the charge of solipsism, allegations of self-refutation, social and moral reservations, and the accusation that RC cannot explain the success of science. Problem: These four objections are sought to be refuted. Results: 1. Solipsism is only troublesome against the background of a realist ontological perspective. 2. The truth-value of any proposition is only defined relative to some ontological context, thus self-refutation, as constituting (...) a logical problem, does not arise. 3. Any ethical argumentation derives from one’s own personal views on ethical matters: their construction being a personal responsibility such that no one else can tell a person how to construct the “right ethics.” 4. In the relativist ontology of radical constructivism, a scientific theory is regarded as a model imposed on natural phenomena; its success is due to the capabilities of its constructor/scientists. Implications: It is found that the objections are based on an (overt or tacit) adoption of the antithetical viewpoint of scientific realism. In other words, radical constructivism is being criticised for not promoting a realist ontology. (shrink)

Purpose: The relativism inherent in radical constructivism is discussed. The epistemic positions of realism and relativism are contrasted, particularly their different approaches to the concept of truth, denoted (respectively) as "truth by correspondence" and "truth by context." I argue that the latter is the relevant one in the domain of science. Findings: Radical constructivism asserts that all knowledge must be constructed by the individual knower. This has implications for teaching, here imagined as a sharing of knowledge (...) between teacher and students: it should be done, not by "reporting the true facts" of whatever is being taught, but rather by "telling a story" about it. An explicit distinction is made between the notions of cognitive and non-cognitive knowledge. It is argued that cognitive knowledge (such as in mathematics and science) is characterised by rules that can be unambiguously agreed on by actors who choose to "play the game"; and hence such knowledge is directly communicable from the teacher to the students. Implications: In telling the story of science, the teacher can verify that the students "have got it right," even though they are all constructing their knowledge individually. In contrast, for non-cognitive knowledge (emotion, preferences, belief, ...) there are no such unambiguous rules to agree on, and therefore it is not communicable in this way: in telling this story, the teacher has no way of verifying that the same knowledge is actually being shared. Conclusion: Science teaching should be carried out in the mode of story-telling; it does not need an epistemology of realism. (shrink)

Problem: Radical constructivism, although having a very successful base in research on mathematics and science education, has not become a generally accepted theory of knowledge. Purpose: This paper discusses possible sources of aversion. Results: The first section makes explicit the unavoidability of accepting the responsibility for one’s thinking and acting, a responsibility that under stressful circumstances one would rather avoid. Another section suggests the origin of the human quest for certain knowledge. The third section introduces the notion of (...) “stickiness of beliefs.” Implications: Constructivism has powerful implications for everyday attitudes and social relations with others. This paper, it is hoped, may induce some readers to investigate these implications. (shrink)

In this essay Clarence Joldersma explores radical constructivism through the work of its most well-known advocate, Ernst von Glasersfeld, who combines a sophisticated philosophical discussion of knowledge and truth with educational practices. Joldersma uses Joseph Rouse's work in philosophy of science to criticize the antirealism inherent in radical constructivism, emphasizing that Rouse's Heideggerian critique differs from the standard realist defense of modernist epistemology. Next, Joldersma develops an alternative conception of truth, in terms of disclosure, based on (...) Lambert Zuidervaart's work in aesthetics. Joldersma concludes by arguing that this notion of truth avoids the pitfalls of both realism and antirealism, giving educational theorists a way forward to accept some of the major insights of constructivism with respect to learning and teaching without having to relinquish a robust notion of truth.

Purpose: Josef Mitterer's essays are considered to be important philosophical advancements of radical constructivism. The main purposes of this paper are, on the one hand, to structure the RC landscape and, on the other hand, to investigate the relations of Mitterer's work to radical constructivism in particular and to philosophy in general. Findings: In this short essay focusing on Mitterer's Das Jenseits der Philosophie, I would like to stress two major points. First, Mitterer's book should be (...) considered as one of several contemporary variants of a radical critique of the semantic turn in the philosophy of science that has taken place since the mid-thirties with the works of Rudolf Carnap, Carl G. Hempel, Hilary Putnam, Alfred Tarski and others. Second, it is by no means clear how to determine the relevance of the new semantic critique for the present and future cognitive status of radical constructivism. The degree of relevance depends crucially on the use of the term "radical constructivism." If radical constructivism, as I will argue, is seen as an umbrella term for a group of empirical research programs, then, by sheer necessity, the relevance can be marginal only. If, however, radical constructivism is viewed as a special form of philosophy of language and/or as a new epistemology, then the importance of Josef Mitterer's approach must be judged within the context of available functional alternatives. Implications: An immediate consequence of this article lies in a renewed emphasis on advancing an empirical research agenda for radical constructivism and in an effective downsizing of radical constructivism as a philosophical perspective.

Open peer commentary on the target article “Who Conceives of Society?” by Ernst von Glasersfeld. Excerpt: I will make the point that radical constructivism von Glasersfeld style unnecessarily plays only a passive or an inactive role. Quite obviously, I want to demonstrate that there is life for radical constructivism outside its seemingly irrelevant function in empirical social research and that it is possible to develop radical constructivism in designs with tangible consequences and effects for (...) the cognitive routines in the social sciences. In short, it is conceivable, despite “Who Conceives of Society?”, that radical constructivism matters. (shrink)

It is well known that the movement of social constructionism rests on foundations laid by Alfred Schutz, but the relationship between his thought and epistemological constructivism has scarcely been addressed. Scholars devoted to the investigation of Schutz’s oeuvre paid little systematic attention to the specific constructivist character of his epistemological position, and proponents of the modern form of epistemological constructivism, second order cyberneticians and radical constructivists have failed to recognize Schutz’s relevance for their project. This paper attempts (...) to show that Schutz’s epistemologically oriented phenomenological-pragmatic theory is compatible with the core tenets of epistemological constructivism and proposes to erect a bridge between Schutzian minded interpretive sociology and constructivism, where arguments could travel both ways. After a brief introduction to Schutz’s theory and Ernst von Glasersfeld’s radical constructivism, I try to point out some topics, where intellectual transfer would be beneficial for both camps.

Purpose: This contribution to the Festschrift honoring Ernst von Glasersfeld gives some insight into the perpetual problem of understanding radical constructivism (RC). Parallels with the Middle Way school of Buddhism appear to shed light on this challenge. Conclusion: The hegemony realism has over the thinking of even the most highly educated in our civilization plays a major role in their failure to understand RC. Those still subject to realism in their thinking interpret statements by those in RC in (...) ways incompatible with RC. Until realists disequilibrate over mismatches between realist expectations and experiences, no alternative way of thinking is accessible to them and misinterpretations of RC will continue. Practical implications: While we cannot change someone else's understanding, in our interactions with them we can focus on creating situations in which those who do not understand us might disequilibrate. If we are successful, they are likely to begin to escape the domination of realism in their thinking. Original value: This insight may enable eventual success in our assisting others to understand RC. (shrink)

Context: Ernst von Glasersfeld’s radical constructivism (RC) develops two positions that are, for the founder of RC, necessarily linked: (1) all accessible realities are perceived realities, (2) perceived realities are “constructed” by “individuals.” Purpose: Von Glasersfeld refers quite often to the theory of evolution. Despite this frequent referring, he uses an evolutionary approach primarily when discussing the viability of constructs. Furthermore, although this use of evolutionary thinking is already restricted, it plays an even smaller part in the reception (...) of RC. The first goal of this paper is to show that as a result of this restriction, individuals as “constructors” do not have enough properties to explain the production of behaviors that we observe. The second goal is to open a perspective on the much richer picture of human cognitive activities that results from the abolishment of this restriction. Approach: Starting with the difference between the interest of philosophers in the problem of “reality” and the problems that organisms have to solve in coping with their needs in varying environments, it is argued that, from an evolutionary perspective, only the perceived or “constructed” realities matter because they are the ones that allow organisms to survive, find partners, cooperate, etc. Hence, both the position of RC and the perception of the environment from an evolutionary perspective are compatible, as claimed by von Glasersfeld. Looking then at the individual, it is argued that RC mainly looks at the construction of realities as ontogenetic processes. Findings: As a result, the constructing individuals do not have enough properties to explain observable behavior or to predict the results of their cognitive constructions. Taking von Glasersfeld’s references to evolutionary theory seriously, it is argued that all organisms, and of course humans, have an evolutionary history that influences their construction of realities. Due to this broadly common background, all humans share an important number of inherited dispositions that influence the constructive processes of individuals. As a result, communication is possible, though not perfect, and there are transcultural (near-)universals and individual dispositions for solving reoccurring problems of social life, as shown by references to current research. Implications: The construct of the constructing individual in RC needs conceptual and interdisciplinary enrichment. (shrink)

Context: Despite many obvious advantages (radical) constructivism has over other philosophies it has failed to become a mainstream philosophy that is widely taught and discussed. Problem: What are the reasons for this failure? Can we identify issues that make it difficult for scholars to accept and even embrace radical constructivist ideas? What is the best way to characterize, explain, and eventually refute objections? Method: By collecting articles from both proponents and opponents of radical constructivism the (...) editors of the special issue tried to present a range of answers to these questions. Results: Some problems are due to known objections to radical constructivism, in particular the idea that being responsible for one’s own constructions opens doors to a “whatever” attitude. Another important insight is that constructivism seems to resemble a river delta with ever branching new sub-disciplines that become increasingly incompatible with each other. Implications: The insights gained from the contributions may lead to a re-orientation of (radical) constructivism that will include less misunderstandings among its critics and to a higher acceptance in the academic community.
