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)

Context: Philosophical debates in recent decades have developed new ways of dealing with old philosophical problems such as reality, truth, knowledge, language, communication, and action. These new approaches deserve serious consideration because they can improve the discourse of radical constructivism. Problem: This paper discusses the following problem: How can we overcome dualistic and ontological approaches to basic philosophical problems – problems that are relevant to all scientific domains? Method: The method applied here can be roughly described as a (...) transition from entities/substantives/identities to actions and processes, the actions and processes from which so-called entities result. Action-orientation – or an actor-based process – is necessarily combined with sense-orientation as provided by culture and society. Results: The paper demonstrates how the problems mentioned above can be reformulated in a non-dualistic and non-ontological way. Implications: Opening up constructivist thinking to insights provided by neighbouring philosophical approaches facilitates interdisciplinary cooperation and helps overcome dualistic remnants – as well as the cognitive one-sidedness of traditional constructivism.

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)

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)

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. (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.

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)

A central question in constructivist studies of science is how the analyst should deal with the material objects handled by scientific practitioners in laboratories. Representatives of ‘radical constructivism’ such as Knorr-Cetina and Latour have gone furthest in exploring the role of these ‘non-humans’ but have also maneuvered themselves in untenable positions due to a fatal conflation of different meanings of the term ‘construction’. The epistemological and ontological commitments of ‘moderate constructivism’ especially of the Strong Program defended by (...) Barnes and Bloor, are more suitable for dealing with the task at hand. While radical constructivists treat the domains of nature and human society as largely coterminous, an alternative ontology stresses that natural reality is never fully absorbed into the world of culture but only interacts with the latter at localizable interfaces such as practices and artifacts. This perspective promises a more relaxed relationship with current forms of scientific realism. (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)

Constructivism rejects the metaphysical position that “truth”, and thus knowledge in science, can represent an “objective” reality, independent of the knower. It modifies the role of knowledge from “true” representation to functional viability. In this interview, Ernst von Glasersfeld, the leading proponent of Radical Constructivism underlines the inaccessibility of reality, and proposes his view that the function of cognition is adaptive, in the biological sense: the adaptation is the result of the elimination of all that is not (...) adapted. There is no rational way of knowing anything outside the domain of our experience and we construct our world of experiences. In addition to these philosophical claims, the interviewee provides some personal insights; he also gives some suggestions about better teaching and problem solving. These are the aspects of constructivism that have had a major impact on instruction and have modified the manner many of us teach. The process of teaching as linguistic communication, he says, needs to change in a way to involve actively the students in the construction of their knowledge. Because knowledge is not a transferable commodity, learning is mainly identified with the activity of the construction of personal meaning. This interview also provides glimpses on von Glasersfeld’s life. (shrink)

Context: Ernst von Glasersfeld’s constructivist epistemology has been a source of intellectual inspiration for several Quebec researchers, particularly in the field of science and mathematics education. Problem: However, what is less well known is the influence that his work had on the direction taken by educational reform in Quebec in the early 2000s as well as the criticisms that his work has given rise to – some of which present a family resemblance to the science wars that swept over the (...) US and France during the 1990s. Results: We begin by outlining the constructivist orientation of Quebec’s educational reform. We then draw a parallel between the above-mentioned science wars and the critics who denounced the constructivist foundations of the reform. In both cases, the bone of contention concerns the usual interpretation of relativism, with the criticisms that we refer to tending to oppose relativism with realism or rationalism. Now, by definition, relativism stands in opposition to absolutism and not to realism, unless the latter manifests itself in an absolutist form (which is the case of some of the critiques). Implications: The fear generated by relativism is by no means new. However, it seems that more than an epistemological controversy is at stake in the current depreciation of positions that, like that of radical constructivism, question the possibility of a “view from nowhere” – that is, aperspectival objectivity – and the resultant knowledge. In the sphere of education, at least in Quebec, there may well be an ideological issue of control over education that is involved. (shrink)

Open peer commentary on the target article “From Objects to Processes: A Proposal to Rewrite Radical Constructivism” by Siegfried J. Schmidt > Upshot: Radical Constructivism should be strictly process-oriented to avoid hidden ontology. S. J. Schmidt provides such a strict process-orientation from a very philosophical viewpoint that, however, still lacks access to empirical research. The purpose of this commentary is to show a way to apply Schmidt’s philosophical framework to empirical research.

Problem: Mitterer's critique of the central argumentations of radical constructivists has been mostly neglected until today. The paper presents and evaluates his criticism and, in the second part, outlines a format of constructivism that tries to draw appropriate consequences. Solution: In his critique Mitterer explains why the radical constructivism represented above all by Maturana, Varela, von Glasersfeld or Roth still remains in a dualistic format. In his view Neurobiology is used in their writings as the indisputable (...) basis for deriving far-reaching epistemological consequences. Therefore constructivism evades self-application. To overcome this serious critique a different approach to constructivist thinking is sketched that operates without using any biological or psychological theories, tries to avoid dualism, and elaborates Mitterer's basic argument that the description of an object and the object under description are the same. Benefits: The paper shows what constructivism can learn from a serious critique and how it can be rewritten in a non-dualistic way. (shrink)

Open peer commentary on the target article “From Objects to Processes: A Proposal to Rewrite Radical Constructivism” by Siegfried J. Schmidt. Upshot: Siegfried J. Schmidt’s timely article offers a fresh look at radical constructivism with an emphasis on contextually and culturally located action as an expression of knowing. Perhaps it remains cautious in making connections with neighbouring philosophical approaches. Two areas that are largely unmentioned are the issue of viability and the conceptual analysis, which remained largely (...) on the sidelines in von Glasersfeld’s later work. (shrink)

Nietzsche appears to adopt a radical Kantian view of objects called constructivism, which holds that the existence of all objects depends essentially on our practices. This essay provides a new reconstruction of Nietzsche's argument for constructivism and responds to five pressing objections to reading Nietzsche as a constructivist that have not been addressed by commentators defending constructivist interpretations of Nietzsche.

Onora O’Neill has contributed enormously to moral philosophy (broadly speaking, including both ethics and political philosophy) by identifying Kant’s unique and powerful form of normative constructivism. Frederick Neuhouser has contributed similarly by showing that all of Hegel’s standards of moral rationality aim to insure the complete development of three distinct, complementary forms of personal, moral and social freedom. However, Neuhouser’s study does not examine Hegel’s justificatory methods and principles. The present article aims to reinforce and extend Neuhouser’s findings by (...) explicating Hegel’s basic principles for justifying practical norms. Surprisingly, Hegel’s basic principles of normative justification are rooted in Kant’s constructivism, as explicated by O’Neill. Hegel’s adaptation and development of Kant’s constructivism results in a powerful form of constructivism about moral principles which merits contemporary interest because it is more powerful and more objectivist than familiar contemporary forms of constructivism. (Slightly revised English translation by the author of „Objektive Gültigkeit zwischen Gegebenem und Gemachtem. Hegels kantischer Konstruktivismus in der praktischen Philosophie“). (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.

A recurring objection to the exploration, development and deployment of radical new technologies is based on their implications with regards to social justice. In this article, using synthetic biology as an example, I explore this line of objection and how we ought to think about justice in the context of the development and introduction of radically new technologies. I argue that contrary to popular opinion, justice rarely provides a reason not to investigate, develop and introduce radical new technologies, (...) although it may have significant implications for how they ought to be introduced. In particular I focus on the time dependency of justice objections and argue that often these function by looking only at the implications of the introduction of the technology at the point of introduction, rather than the more important long-term impact on patterns of distribution and opportunity.

This commentary to Nescolarde-Selva and Usó-Doménech’s (Reality, systems and impure systems. Foundations of Science 2013) links ideas in their paper to radical constructivism and raises two questions. (1) Would it be helpful to substitute the constructivist notion of viability for the traditional notion of truth with its connotations of relating language and reality? (2) Is the link made to issues in ontological philosophy important since the implicit constructivist epistemology of the paper considers mathematical ideas are just as real (...) as ideas about objects.

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)

In his book, The Justification of Scientific Change, Carl Kordig claims that the radical meaning variance view of Feyerabend and others becomes ensnared in a self-referential paradox. The accusation fails because it rests upon a confusion of that view with its "counterparts" in other linguistic/theoretical contexts.

To what extent can constructive mathematics based on intuitionistc logic recover the mathematics needed for spacetime physics? Certain aspects of this important question are examined, both technical and philosophical. On the technical side, order, connectivity, and extremization properties of the continuum are reviewed, and attention is called to certain striking results concerning causal structure in General Relativity Theory, in particular the singularity theorems of Hawking and Penrose. As they stand, these results appear to elude constructivization. On the philosophical side, it (...) is argued that any mentalist-based radical constructivism suffers from a kind of neo-Kantian apriorism. It would be at best a lucky accident if objective spacetime structure mirrored mentalist mathematics. the latter would seem implicitly committed to a Leibnizian relationist view of spacetime, but is it doubtful if implementation of such a view would overcome the objection. As a result, an anti-realist view of physics seems forced on the radical constructivist. (shrink)

‘Radical enactivism’ (Hutto and Myin 2013, 2017) eschews representational content for all ‘basic’ mental activities. Critics have argued that this view cannot make sense of the workings of the imagination. In their recent book (2017), Hutto and Myin respond to these critics, arguing that some imaginings can be understood without attributing them any representational content. Their response relies on the claim that a system can exploit a structural isomorphism between two things without either of those things being a semantically (...) evaluable representation of the other. I argue that even if this claim is granted, there remains a problem for radically enactive accounts of imagining, namely that the active establishing and maintenance of a structural isomorphism seems to require representational content even if the exploitation of such an isomorphism, when established, does not.

Problem: What is it that Ernst von Glasersfeld brought to mathematics education with radical constructivism? Method: Key ideas in the author’s early thinking are related to ideas that are central in constructivism, with the aim of showing their importance in math education. Results: The author’s initial thinking about constructivism began with Toulmin’s view of thinking as evolving. Ernst showed how Piaget’s genetic epistemology implied an epistemology that was not about ontology. Continuing with an analysis of the (...) way radical and trivial constructivism were received by the mathematics education community, implications of Ernst’s ideas are considered. Implications: These include the need to consider major changes in ways content is introduced to children, to consider carefully the language used to describe children’s emerging mathematical ideas, and to consider new conjectures and also how we think about the foundations of mathematics. Ultimately the value of RC is the way it reinspires belief in the possibility and importance of human growth. (shrink)

Constructivism is a theory that believes moral judgments are not real things but they are constructed by practical reason in a rational procedure for resolving practical problems in front of us. Christine Korsgaard, a contemporary American philosopher, is a Kantian constructivist, whose theory I consider in this paper. She is a radical constructivist and disagrees with moral realism and denies moral truths even as abstract facts. According to Korsgaard moral judgments are constructed by rational agents. She believes moral (...) and political principles are generally solutions to human practical problems. She justifies the normativity of moral obligations from this point that they are constructed by agent for resolving his problems. There are some objections to Korsgaard’s constructivism; one of them is to place humanity as the source of value. Keywords: Korsgaard, constructivism, practical problem, humanity. Introduction One of the traditional problems in moral philosophy is the nature and entity of moral truths and judgments. Do humans themselves make and construct them or are they facts and truths in the world which humans just discover? Are moral truths and values subjective or objective? Subjectivism and objectivism have been two old rivals in this question. But some philosophers have proposed a new theory between them that is called Constructivism. According to this theory, moral truths are not real and objective, but are constructed by human practical reason. In this view, an action is morally right when there is a sufficient reason to perform it. In this paper I will discuss Korsgaard’s constructivism. 1. Definition of Constructivism Constructivism is a theory about the justification of moral principles. It is the view that moral principles are the ones agents would agree with or endorse if they were to engage in a hypothetical or idealized process of rational deliberation. The differences about related criteria for this rational process and deliberation have produced several varieties of constructivism like Humean, Aristotelian, and Kantian. (shrink)

Purpose: My first purpose is to present an epistemological and ideological analysis of various conceptions of the mind--culture relationship and to state why it is fruitless to set them against each other. My second purpose is to answer the following two questions within the framework of cultural cognitive development: (1) How do I understand and explain the interaction between two cultural actors, one of whom is myself? (2) How do I model cultural intersubjectivity? Addressing these two aims, I want to (...) make the nature of observer participation explicit to myself, then to the reader. Design: I describe the personal schemes I use in my cross-cultural research. After defining and comparing different conceptual and methodological instruments, I go on to argue in favor of an experimental methodological approach based on a naturalistic constructivist epistemological framework. Findings: Among the potential ontological and epistemological conceptions related to the human mind, I consciously argue for a naturalistic ontology and a constructivist epistemology. In line with this philosophical view, the knowledge on the cognitive development of children pertaining to different cultures appears as my personal scheme's production. Such production is a permanent object of debate in the scientific community and in the wider community of studied subjects. Original value -- The ideas and concepts developed in the present paper are neither new nor innovative. I relate the conceptual shift from a positivist to a radical constructivist epistemology that was necessary in order for me to be able to study the relationship between culture and children's cognitive development. Implications: While the present discussion may not be innovative from a radical constructivist point of view, it is so from the point of view of mainstream developmental psychology. (shrink)

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)

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)

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.

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)

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.

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.

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)

Context: the position of pure and applied mathematics in the epistemic conflict between realism and relativism. Problem: To investigate the change in the status of mathematical knowledge over historical time: specifically, the shift from a realist epistemology to a relativist epistemology. Method: Two examples are discussed: geometry and number theory. It is demonstrated how the initially realist epistemic framework – with mathematics situated in a platonic ideal reality from where it governs our physical world – became untenable, with the advent (...) of non-Euclidean geometry and the increasing abstraction of the number concept. Results: Radical constructivism offers an alternative relativist epistemology, where mathematical knowledge is constructed by the individual knower in a context of an axiomatic base and subject items chosen at her discretion, for the purpose of modelling some part of her personal experiential world. Thus it can be expedient to view the practice of mathematics as a game, played by mathematicians according to agreed-upon rules. Constructivist content: The role played by constructivism in the formulation of mathematics is discussed. This is illustrated by the historical transition from a classical (platonic) view of mathematics, as having an objective existence of its own in the “realm of ideal forms,” to the now widely accepted modern view where one has a wide freedom to construct mathematical theories to model various parts of one’s experiential world.

Constructivism comes in a number of forms. Some are models of learning which involve few, if any, startling epistemological claims. On the other hand, what has been promoted as ‘radical constructivism’ holds that our concepts cannot be related directly to an external reality, and that claims for the objectivity of knowledge are therefore unjustified. This standpoint is an anti-realist version of evolutionary epistemology. I argue that it relies on a mistaken interpretation of the Darwinian theory of evolution (...) by natural selection, and that its application of this model to the relation between knowledge and the world is also mistaken.

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.

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.

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.

Context: Traditional research on the fiction/non-fiction distinction is the fruit of an essentialist methodology in which the procedures of ontologizing and textualizing are assumed as obligatory. Ontologizing and textualizing form the basic discursive technique, in which analyses are focused on the object as the semantic centre. Theory of literary fiction – deeply rooted in Alexius Meinong’s theory of non-existent objects – is object-orientated and, as a result, is always ontologically involved/engaged. Problem: The re-description of the fundamental literary problems as a (...) kind of epistemological experiment for which non-dualizing philosophy is a foundation. Considerations are aimed at providing answers/solutions to the three following issues: 1. Is it possible to connect non-dualism with a literary discourse about literary fiction? 2. What difference does the non-dualizing perspective make in comparison to a philologically-orientated discourse? 3. What difference does the non-dualizing perspective make in comparison to the constructivist approach to the problem of fiction? Approach: Mitterer’s non-dualism is considered from both the context of ontologically-orientated discourse about fiction and literary research and the context of constructivist discourse about fiction. Results: Mitterer’s non-dualizing conception may be considered a foundation of a radical non-essentialist way of thinking about literary fiction. As a result, the philologically-orientated research on literary text, focused on the explanation of its semantics, would rather move towards a culturally-, pragmatically-, and/or sociologically- orientated type of discourse. The notion of (literary) fiction should be reformulated as follows: fiction is not the reason for interpretation; fiction is the result of interpretation because the description comes from the object of speech (from-object-cognition). Implications: This is only an introduction to the project of a potential non-ontologizing discourse about literary fiction. Therefore it should be developed and discussed as the option for the dualizing type of the discourse as it still stirs up a lot of controversies. (shrink)

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.

Open peer commentary on the article “Learning How to Innovate as a Socio-epistemological Process of Co-creation: Towards a Constructivist Teaching Strategy for Innovation” by Markus F. Peschl, Gloria Bottaro, Martina Hartner-Tiefenthaler & Katharina Rötzer. Upshot: The aims of this commentary are to pose a few reactions to the design framework, enactment, and data and analyses of the reported investigation, and to offer additional overall perspectives on radical constructivism as a potential framework for classroom teaching (and specifically the teaching (...) of school mathematics.

Open peer commentary on the target article “From Objects to Processes: A Proposal to Rewrite Radical Constructivism” by Siegfried J. Schmidt. Upshot: In the 1990s the emergence of radical constructivism as a meta-theory inspired many scientific disciplines. Since more or less simple realistic concepts of the media as mirroring the world prevailed, communication science was challenged to re-think the relation of media and reality as well. Recently, criticism of constructivist media theory has grown, while those constructivst (...) approaches have not developed any further. Thus, the commentary examines the potential for Schmidt”s process-oriented constructivism, which is interpreted as part of a non-dualistic paradigm, to revitalize the debate. I will argue that the idea of acting as a perpetual process of positings and presuppositions [Setzungen und Voraussetzungen] can especially be related to current research on media and memory.

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.
