Wolfgang Köhler (1887-1967) was one of the founders of Gestalt psychology, the influential school that argues that perception is best understood as an organized pattern rather than as separate parts. Penetrating in its insights and lucid in presentation, Gestalt Psychology (1947) is Köhler's definitive statement of Gestalt theory.

ls it possible to understand not only linguistic expressions and actions but also persons? According to common sense it surely is. Here it is argued that to understand a person a fourfold knowledge is required, although this knowledge is not identical with the understanding of a person. The understanding of a person is cognitive, but neither complete nor scientific.

This essay is about the Wolfgang Köhler’s philosophical ideas expressed in his The Place of Value in a World of Facts of 1938. Köhler, who strongly supports a scientific world view, considers the question as to whether science is able to cope with human values, besides natural facts. Relying upon phenomenological analyses, and on his previous researches in natural philosophy, Köhler introduces his doctrine of “epistemological dualism”. From a historical point of view, this theory exhibits some similarity with the (...) philosophical ideas expressed by Köhler’s Berlin mentor Carl Stumpf. It is argued that Köhler’s epistemological dualism actually supports ontological monism and aims at offering a unified view of natural facts and human values. (shrink)

It will be argued that the basic theoretical assumptions of logical empiricism do not destroy the possibility of practical reasoning, because the noncognitivity of normative or evaluative statements still guarantees rational argument over practical questions and problems. Therefore, no logical inconsistency exists between logical empiricism, its noncognitivist meta-ethics and socialist politics. In particular, logical empiricism is not committed to indifference concerning reactionary political programmes, although it itself entails no individual political programme.

The following article is only in part a review of Rorty’s “Philosophy and the Mirror of Nature”. First I sketch the development of the two leading metaphors, which Rorty considers as being central for epistemology, namely the mirror of nature and the eye of the mind. Then I try to bring out the antirealist implications of Rorty’s socalled “epistemological behaviorism” and to make sense of his slogan that truth is merely warranted assertability which in my view seems not to be (...) in line with his favouring truth-conditional semantics. Thirdly I point to some possible consequences for the social sciences of using the antirealist “criteria!” semantics of the later Wittgen stein, one of Rorty’s heroes. (shrink)

Logical Empiricism, i.e. its noncognitivism, does not destroy practical rationality because it is compatible with a rational decision on normative questions by way of consequentialist reasoning according to decision theory. It is argued that the contention that Logical Empiricism destroys practical rationality is based on a confusion of a rational decision on normative questions with the interpretation of the meaning of the answers to these questions. It is further argued that a rational decision on normative questions is only possible as (...) far as the normative status of actions is concerned. It is not possible as far as the evaluative premises about basic values are concerned. Finally it is said that a rational decision on normative questions is principally deductive. Good-reason’ s-approach and practical syllogism are therefore only enthymematic and transformable into logical deduction. Of course, proving basic values or moral principles by way of logical deduction is both as impossible as needless. (shrink)

This article investigates how subjects determine minimum selling prices for lotteries. We design an experiment where subjects have at every moment an incentive to state their minimum selling price and to adjust the price, if they believe that the price that they stated initially was not optimal. We observe frequent and sizeable price adjustments. We find that random pricing models cannot explain the observed price patterns. We show that earlier prices contain information about future price adjustments. We propose a model (...) of Stochastic Pricing that offers an intuitive explanation for these price adjustment patterns. (shrink)

Wolfgang Spohn’s paper I think clearly places him in the forefront of research on the theory of lawlikeness, and simultaneously on the methodology of inductive reasoning.

Info in English (book is in German): The book "Schöpferische Freiheit" ("Creative Freedom") is considered the third major work of Gestalt psychologist Wolfgang Metzger (1899-1979) - along with his "Psychology" and the "Laws of Seeing". According to Michael Stadler and Wolfgang Crabus, Metzger's real achievement in the further development of Gestalt theory is expressed in this book: "Metzger develops here, on the basis of Köhler's natural philosophical ideas of 'physical Gestalten' (1920) and incorporating the teachings of Zen Buddhism (...) ... a theory of education for creative thought and action. ... This book perhaps most clearly expresses the ethic of free self-determination of human thought and action inherent in Gestalt theory." "Creative Freedom" has lost none of its relevance since its last edition in 1962. It can be considered a foundational work of a Gestalt theory of the living. Jürgen Kriz writes in his preface to the now new edition: "It is extremely gratifying that this central work not only of Gestalt psychology, but (at least from my point of view) also of humanistic psychology and psychotherapy is being reissued. It is currently available only in (all too few) libraries and single antiquarian copies. Yet the central messages and insights of Wolfgang Metzger's 'Creative Freedom' are more relevant than ever: as a necessary warning against the aberrations of an increasing functionalization, medicalization, and progress-believing optimization (for whatever purposes) of the human being in our time." The new edition is accompanied by comments on the topicality and relevance of the work for education and teaching (Marianne Soff) as well as for psychotherapy (Gerhard Stemberger). Buchinformation: Die „Schöpferische Freiheit“ gilt als das dritte Hauptwerk des Gestaltpsychologen Wolfgang Metzger (1899-1979) – neben seiner „Psychologie“ und den „Gesetzen des Sehens“. Nach Michael Stadler und Wolfgang Crabus kommt in diesem Buch Metzgers eigentliche Leistung der Weiterentwicklung der Gestalttheorie zum Ausdruck: „Metzger entwickelt hier auf der Grundlage von Köhlers naturphilosophischen Ideen der ‚physischen Gestalten‘ (1920) und unter Einbeziehung der Lehren des Zen-Buddhismus … eine Theorie der Erziehung zum schöpferischen Denken und Handeln. … Dieses Buch drückt vielleicht am deutlichsten die der Gestalttheorie inhärente Ethik der freien Selbstbestimmung menschlichen Denkens und Handelns aus.“.
