    Extending the Hegselmann–Krause Model III: From Single Beliefs to Complex Belief States.Igor Douven & Alexander Riegler - 2009 - Episteme 6 (2):145-163.
    In recent years, various computational models have been developed for studying the dynamics of belief formation in a population of epistemically interacting agents that try to determine the numerical value of a given parameter. Whereas in those models, agents’ belief states consist of single numerical beliefs, the present paper describes a model that equips agents with richer belief states containing many beliefs that, moreover, are logically interconnected. Correspondingly, the truth the agents are after is a theory (a set of sentences (...)

    Epistemological Odyssey: Introduction to Special Issue on the Diversity of Enactivism and Neurophenomenology.S. Vörös, T. Froese & A. Riegler - 2016 - Constructivist Foundations 11 (2):189-204.
    Context: In the past two decades, the so-called 4E approaches to the mind and cognition have been rapidly gaining in recognition and have become an integral part of various disciplines. Problem: Recently, however, questions have been raised as to whether, and to what degree, these different approaches actually cohere with one another. Specifically, it seems that many of them endorse mutually incompatible, perhaps even contradictory, epistemological and metaphysical presuppositions. Method: By retracing the roots of an alternative conception of mind and (...)

  3. Second-Order Science: A Vast and Largely Unexplored Science Frontier.K. H. Müller & A. Riegler - 2014 - Constructivist Foundations 10 (1):7-15.
    Context: Many recent research areas such as human cognition and quantum physics call the observer-independence of traditional science into question. Also, there is a growing need for self-reflexivity in science, i.e., a science that reflects on its own outcomes and products. Problem: We introduce the concept of second-order science that is based on the operation of re-entry. Our goal is to provide an overview of this largely unexplored science domain and of potential approaches in second-order fields. Method: We provide the (...)

    Extending the Hegselmann–Krause Model I.Igor Douven & Alexander Riegler - 2010 - Logic Journal of the IGPL 18 (2):323-335.
    Hegselmann and Krause have developed a simple yet powerful computational model for studying the opinion dynamics in societies of epistemically interacting truth-seeking agents. We present various extensions of this model and show their relevance to the investigation of socio-epistemic questions, with an emphasis on normative questions.

  5. Constructivist Artificial Life, and Beyond.Alexander Riegler - 1992 - In Barry McMullin (ed.), Proceedings of the Workshop on Autopoiesis and Perception. Dublin City University: Dublin, Pp. 121–136.
    In this paper I provide an epistemological context for Artificial Life projects. Later on, the insights which such projects will exhibit may be used as a general direction for further Artificial Life implementations. The purpose of such a model is to demonstrate by way of simulation how higher cognitive structures may emerge from building invariants by simple sensorimotor beings. By using the bottom-up methodology of Artificial Life, it is hoped to overcome problems that arise from dealing with complex systems, such (...)

    Towards a Radical Constructivist Understanding of Science.Alexander Riegler - 2001 - Foundations of Science 6 (1-3):1-30.
    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 (...)

    A New Course of Action.K. H. Müller & A. Riegler - 2014 - Constructivist Foundations 10 (1):1-6.
    Context: The journal Constructivist Foundations celebrates ten years of publishing articles on constructivist approaches, in particular radical constructivism. Problem: In order to preserve the sustainability of radical constructivism and regain its appeal to new generations of researchers, we set up a new course of action for and with the radical constructivist community to study its innovative potential. This new avenue is “second-order science.” Method: We specify two motivations of second-order science, i.e., the inclusion of the observer, and self-reflexivity that allows (...)

  9. Editorial. The Constructivist Challenge.A. Riegler - 2005 - Constructivist Foundations 1 (1):1--8.
    Purpose: This is an attempt to define constructivism in a pluralistic way. It categorizes constructivist work within a three-dimensional space rather than along one dimension only. Practical implications: The interdisciplinary definition makes it possible to perceive the rather heterogeneous constructivist community as a coherent and largely consistent scientific effort to provide answers to demanding complex problems. Furthermore it gives authors of Constructivist Foundation the opportunity to locate their own position within the community. Conclusion: I offer a catalogue of ten points (...)

    A Plea for Not Watering Down the Unseemly: Reconsidering Francisco Varela's Contribution to Science.Sebastjan Vörös & Alexander Riegler - 2017 - Constructivist Foundations 13 (1):1-10.
    In the past three decades, the work of Varela has had an enormous impact on current developments in contemporary science. Problem: Varela’s thought was extremely complex and multifaceted, and while some aspects - notably his contributions to the autopoietic theory of living and enactivist approach to cognition - have gained widespread acclaim, others have been ignored or watered down. Method: We identify three dimensions of Varela’s thought: anti-realism of the “middle way”; anti-foundationalism of the circular/recursive onto-epistemology; and ethical/social implications of (...)

    Building a Science of Experience: Neurophenomenology and Related Disciplines.C. Valenzuela-Moguillansky, A. Vásquez-Rosati & A. Riegler - 2017 - Constructivist Foundations 12 (2):131-138.
    Context: More than 20 years ago Varela initiated a research program to advance in the scientific study of consciousness, neurophenomenology. Problem: Has Varela’s neurophenomenology, the solution to the “hard problem,” been successful? Which issues remain unresolved, and why? Method: This introduction sketches the progress that has been made since then and links it to the contributions to this special issue. Results: Instead of a unified research field, today we find a variety of different interpretations and implementations of neurophenomenology. We argue (...)

    Mapping the Varieties of Second-Order Cybernetics.K. H. Müller & A. Riegler - 2016 - Constructivist Foundations 11 (3):443-454.
    Context: Although second-order cybernetics was proposed as a new way of cybernetic investigations around 1970, its general status and its modus operandi are still far from obvious. Problem: We want to provide a new perspective on the scope and the currently available potential of second-order cybernetics within today’s science landscapes. Method: We invited a group of scholars who have produced foundational work on second-order cybernetics in recent years, and organized an open call for new approaches to second-order cybernetics. The accepted (...)

    Niklas Luhmann and the Sociological Turn in Constructivism.A. Riegler & A. Scholl - 2012 - Constructivist Foundations 8 (1):1-4.
    Context: Niklas Luhmann is considered to be a major proponent of the constructivist movement who based his highly complex sociological theory on constructivist concepts such as Maturana’s autopoiesis and Spencer Brown’s distinction. Problem: Despite heavily borrowing from constructivism, there are doubts as to whether his epistemological standpoint was properly constructivist. Method: In six papers and 14 Open Peer Commentaries, Luhmann’s epistemological understanding, understanding of science, and use and development of constructivist concepts is examined. Results: The authors’ papers and commentaries cover (...)

    Non-Dualism: A New Understanding of Language.A. Riegler & S. Weber - 2013 - Constructivist Foundations 8 (2):139-142.
    Context: Non-dualism suggests a new way of utilizing language without the assumption of categorically extralinguistic objects denoted by language. Problem: What is the innovative potential, what is the special value of non-dualism for science? Is non-dualism a fruitful conceptual revision or just a philosophical thought experiment with no or little significance for science? Method: We provide a concise introduction to non-dualism’s central new proposals and an overview of the papers. Results: Fourteen contributors show how this way of thinking and speaking (...)

    Non-Dualizing From Now On?A. Riegler & S. Weber - 2008 - Constructivist Foundations 3 (3):120-122.
    Excerpt: Is Josef Mitterer's non-dualizing philosophy yet another philosophical flavor, of which there are so many in the academic world? Yet another philosophical trinket that arouses the short-lived attention of some people and disappears quickly thereafter? Yet another dalliance without implications either for philosophy or for science? We are convinced of the contrary. For many years Mitterer has steadily built up a reputation as an innovative but at the same time also very careful thinker. His claims have been discussed in (...)

    Maturana Across the Disciplines.Pille Bunnell & Alexander Riegler - 2011 - Constructivist Foundations 6 (3):287-292.
    Context: Humberto Maturana has generated a coherent and extensive explicatory matrix that encompasses his research in neurophysiology, cognition, language, emotion, and love. Purpose: Can we formulate a map of Maturana’s work in a manner that is consistent with the systemic matrix it represents and that serves as an aid for understanding Maturana’s philosophy without reifying its representation? Method: Our arguments are based on experience gained from teaching and presentations. Results: We present a map that that represents Maturana’s main contributions as (...)

    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 (...)

    Context: Ernst von Glasersfeld introduced radical constructivism in 1974 as a new interpretation of Jean Piaget’s constructivism to give new meanings to the notions of knowledge, communication, and reality. He also claimed that RC would affect traditional theories of education. Problem: After 40 years it has become necessary to review and evaluate von Glasersfeld’s claim. Also, has RC been successful in taking the “social turn” in educational research, or is it unable to go beyond “private worlds? Method: We provide an (...)

    Legacy of a Great Thinker. Editorial for the Commemorative Issue for Ernst von Glasersfeld.A. Riegler & H. Gash - 2011 - Constructivist Foundations 6 (2):135-137.
    Context: On 12 November 2010, Ernst von Glasersfeld passed away. He was one of the most important, if not the most important, proponents of constructivist philosophy. Problem: In his life Ernst influenced many other scientists and philosophers. By whom was he himself influenced; who shaped his intellectual development? By collecting contributions from those who knew him closely or have an excellent understanding of radical constructvism we aim at presenting a cartography of the past and current state of affairs of radical (...)

    Computation, Cognition and Constructivism: Introduction to the Special Issue.A. Riegler, J. Stewart & T. Ziemke - 2013 - Constructivist Foundations 9 (1):1-6.
    Context: Most constructivist discourse is situated at the philosophical-conceptual level, where arguments appeal to the intuition of the reader, while formal-computational models have only been taken into account to a very limited degree so far. Problem: Two types of problems need to be addressed: Synthetically, can constructivist concepts be turned into actual computational implementations? Can these be further conceptual developments in constructivist theory as such, or are they just an application thereof? Conceptually, does the notion of computation square with constructivist (...)
