  1. 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 (...)

    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 (...)

    Extending the Hegselmann–Krause Model I.Igor Douven & Alexander Riegler - 2009 - 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 (...)

    The Evolution of Complexity the Violet Book of "Einstein Meets Magritte".Francis Heylighen, Johan Bollen & Alexander Riegler - 1999 - Springer.
    The Evolution of Complexity is addressed to a broad audience of academics and researchers from different disciplines, who are interested in the picture of our world emerging from the new sciences of complexity. This book reviews the new concepts proposed by the diverse theories of evolution, self-organisation, general systems, cybernetics, and the `complex adaptive systems' approach pioneered by the Santa Fe institute. The thread which holds everything together is the growth of complexity during the history of the universe: from elementary (...)

  10. 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 (...)

  11. Thinking in Eigenbehaviors as a Transdisciplinary Approach.Manfred Füllsack & Alexander Riegler - 2017 - Constructivist Foundations 12 (3):239-245.
    Context: By proposing to regard objects as “tokens for eigenbehavior,” von Foerster’s seminal paper opposes the intuitive subject-object dualism of traditional philosophy, which considers objects to be instances of an external world Problem: We argue that this proposal has two implications, one for epistemology and one for the demarcation between the natural sciences and the humanities. Method: Our arguments are based on insights gained in computational models and from reviewing the contributions to this special issue. Results: Epistemologically, von Foerster’s proposal (...)

    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 (...)

    Editorial: Can Radical Constructivism Become a Mainstream Endeavor?Alexander Riegler & Andreas Quale - 2010 - Constructivist Foundations 6 (1):1-5.
    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 (...)
