Purpose: Commenting on the transcript of a lecture. Findings: The document reconstructs the development of the original 1973 lecture by Heinz von Foerster into his best-known paper, On Constructing a Reality. Many aspects of that paper can be identified as being shaped through interaction with the audience. Implications: The lecture documented here was a forerunner of a central paper in constructivism.

Zwei ältere Herren, einer Biophysiker, der andere Psychologe, treffen sich, um über die Vergangenheit zu sprechen. Das könnte eine ganz alltägliche Geschichte sein. Allerdings handelt es sich bei den beiden Protagonisten um die Väter des Radikalen Konstruktivismus. Der Bitte ihre Verlegers, ein Tonband mitlaufen zu lassen, kamen sie gerne nach. Ein Glücksfall, wie sich im Nachhinein herausstellt. in einem ungemein spannenden, quicklebendigen Dialog werden komplexe wissenschaftliche Fragen auf allgemeinverständliche Weise thematisiert: Was haben Kurzwellen und Kühe gemein? Warum vergräbt ein Eichhörnchen (...) eine Nuss? Was verbindet diese Frage mit der folgenden: Was kommt zuerst - Sprache oder Bewusstsein? (shrink)

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 (...) contributions are discussed and mapped. We also investigate the relations between second-order cybernetics and second-order science. Results: We present a coherent outlook on the scope of second-order cybernetics today, identify a general methodology of science and show that second-order cybernetics can be used in a large number of disciplines that go well beyond purely scientific domains. These results are based on a new epistemic mode “from within,” which can be traced back directly to von Foerster. We also arrived at the conclusion that from its early years onwards second-order cybernetics was developed in two different ways, so that second-order cybernetics and second-order science operate in different domains. Implications: Both the coherent perspective of the scope of second-order cybernetics with a new five-part agenda and the outline for a general methodology of science based on a new epistemic mode that was created within and for second-order cybernetics demonstrate the growing importance of reflexivity in science, which, so far, has not been widely recognized.

Upshot: For communicating second-order science, von Foerster’s ethical imperative provides a viable starting point. Proceeding from this, we plead in favour of emphasising the common grounds of diverging scientific opinions and of various approaches in second-order science instead of focussing on the differences. This will provide a basis for communication and stimulate scientific self-reflection.

This article deals with the research tradition of Radical Constructivism and proposes four central claims for its theoretical, methodological and epistemic orientation and status. First, Radical Constructivism should be viewed as a comprehensive empirical research tradition with an emphasis on cognition, learning, living systems and organization which, in addition, developed a new general methodology for scientific operations. Second, the main opponent of Radical Constructivism, especially in the research program of Heinz von Foerster, does not lie in philosophical or epistemological (...) terrains but in the area of the general scientific methodology and in its conventional mode of exploring the world. Third, Radical Constructivism proposed a new and alternative way for scientific explorations and world-making which produces, additionally, tangible and non-trivial effects with respect to scientific outcomes. Fourth, due to this new way of scientific world-making and due to its novel scientific methodology Radical Constructivism was only marginally interested in epistemological issues. Instead, the empirical research tradition of Radical Constructivism offered intriguing answers why the varieties of scientific realism and its allies like scientific objectivity seem so appealing and almost self-evident. -/- .

This first volume of Wittgenstein's Last Writings on the Philosophy of Psychology was written between October 1948 and March 1949, when the philosopher had moved to Dublin and was having one of his most fruitful working periods. He then finished work which he had begun in 1946 and which in its entirety constitutes the source material for Part II of the "Philosophical Investigations". When, later in 1949, Wittgenstein composed the manuscript for Part II he selected more than half the remarks (...) for it from the Dublin manuscript. Although this material is a direct continuation of the writings which make up the two volumes of the Remarks on the Philosophy of Psychology it deserves more than they to be regarded as a "preliminary study" for the second part of Wittgenstein's "chef-d'oeuvre".

Background: Only data of published study results are available to the scientific community for further use such as informing future research and synthesis of available evidence. If study results are reported selectively, reporting bias and distortion of summarised estimates of effect or harm of treatments can occur. The publication and citation of results of clinical research conducted in Germany was studied.Methods: The protocols of clinical research projects submitted to the research ethics committee of the University of Freiburg in 2000 were (...) analysed. Published full articles in several databases were searched and investigators contacted. Data on study and publication characteristics were extracted from protocols and corresponding publications.Results: 299 study protocols were included. The most frequent study design was randomised controlled trial , followed by uncontrolled studies , laboratory studies and non-randomised studies . 182 were multicentre studies including 97 international collaborations. 152 of 299 had commercial funding and 46 non-commercial funding. 109 of the 225 completed protocols corresponded to at least one full publication ; the publication rate was 48%. 168 of 210 identified publications were cited in articles indexed in the ISI Web of Science. The median was 11 citations per publication .Conclusions: Results of German clinical research projects conducted are largely underreported. Barriers to successful publication need to be identified and appropriate measures taken. Close monitoring of projects until publication and adequate support provided to investigators may help remedy the prevailing underreporting of research. (shrink)

This bilingual volume—English and German on facing pages—brings together the writings Wittgenstein composed during his stay in Dublin between October 1948 and March 1949, one of his most fruitful periods. He later drew more than half of his remarks for Part II of Philosophical Investigations from this Dublin manuscript. A direct continuation of the writing that makes up the two volumes of Remarks on the Philosophy of Psychology, this collection offers scholars a glimpse of Wittgenstein's preliminary thinking on one of (...) his most important works. G. H. von Wright and Heikki Nyman both teach at the University of Helsinki. (shrink)

This bilingual edition of the Remarks on the Philosophy of Psychology presents the first English translation of an essential body of Wittgenstein's work. It elaborates Wittgenstein's views on psychological concepts such as expectation, sensation, knowing how to follow a rule, and knowledge of the sensations of other persons. It also shows strong emphasis on the "anthropological" aspect of Wittgenstein's thought.

It is shown that the covariance together with the quantum principle speak for an affinely connected structure which, for distances greater than Planck’s length, goes over in a metrically connected structure of space-time.

Excerpt: In 1995, the Leo Apostel Centre in Brussels, Belgium, organised an international conference called ``Einstein meets Magritte''. Nobel prize winner Ilya Prigogine held the opening lecture at the conference, and Heinz von Foerster's lecture was scheduled last... Heinz von Foerster was enchanted by the conference theme and -- in the spirit of surrealist Belgian painter René Magritte -- had chosen an appropriate title for his talk: ``Ceci n'est pas Albert Einstein''. ... [H]e was delighted to grant the (...) organisers the following interview, in which he tells us about an even longer journey -- that of his remarkable life and scientific career. (shrink)

Intent and mitigating circumstances play a central role in moral and legal assessments in large-scale industrialized societies. Al- though these features of moral assessment are widely assumed to be universal, to date, they have only been studied in a narrow range of societies. We show that there is substantial cross-cultural variation among eight traditional small-scale societies (ranging from hunter-gatherer to pastoralist to horticulturalist) and two Western societies (one urban, one rural) in the extent to which intent and mitigating circumstances influence (...) moral judgments. Although participants in all societies took such factors into account to some degree, they did so to very different extents, varying in both the types of considerations taken into account and the types of violations to which such considerations were applied. The particular patterns of assessment characteristic of large-scale industrialized societies may thus reflect relatively recently culturally evolved norms rather than inherent features of human moral judgment.

Summary: The aim of this collection is to provide a two-fold access to von Foerster's legacy and his work at the Biological Computer Laboratory, the institution he founded and directed at the University of Illinois at Urbana-Champaign from 1958 to 1976. It represents a precious contribution for the understanding of BCL, a crucial but still not properly understood chapter in the history of cybernetics and, more generally, of cognitive science. It is greatly recommended.
