This paper explains Viktor von Weizsäcker’s Gestaltkreis model as a reinterpretation of Jakob von Uexküll’s Funktionskreis. Also derived from the Funktionskreis is Thure von Uexküll’s Situationskreis model. Both Weizsäcker’s Gestaltkreis and Thure von Uexküll’s Situationskreis have evolved in the context of integrated medicine in Germany throughout the twentieth century. Focusing on the role of language in health and medicine, this paper addresses important concepts associated with the project of integrated medicine in Germany, especially the biographical approach practiced by Viktor von (...) Weizsäcker and developed by Thure von Uexküll through the concept of the biographical organ. While their efforts to reform the practice of medicine and the training of physicians were unsuccessful, recent research in the psychology of language and health and recommendations for more patient-centered communication resonate with the principles underlying Viktor von Weizsäcker’s and Thure von Uexküll’s integrated medicine.

This paper investigates the reception and discussion of Jakob von Uexküll’s biological theory by two German thinkers of his time, Helmuth Plessner and Kurt Goldstein. It demonstrates how their bio-philosophical perspectives are on the one hand indebted to Uexküll’s theory and, on the other, critical of its tendency to excessively harmonize the relationship between living beings and their environment. This original critical reading of the _Umweltlehre_ is rooted in ambiguities within Uexküll’s own thought - between a dynamic conception of the (...) organism-environment relationship and the idea of "conformity to a plan" -,, which is here examined in the second section. In the third and fourth sections we will then focus on Plessner and Goldstein respectively, demonstrating how for these two authors the harmony between organism and environment is not an original state, but only reveals itself against the background of a tension; as such, it can only be partial, unstable and always changing. The two thinkers avoid the rigid alternative between Darwin’s concept of adaptation (_Anpassung_) and Uexküll’s “fitting into” (_Einpassung_) by theorizing the ideal state of the relationship between organism and environment in terms of “adequacy” (_Adäquatheit_) and “adaptability” (_Adaptiertheit_). Between organism and environment there is neither absolute separation nor perfect harmony, but rather a gap which can never be definitively fixed. (shrink)

This paper examines the efforts in evolution research to understand form’s structure that developed in Italy during the first half of the twentieth century. In particular, it analyzes how the organic approach in biology and the study of organic form merged in the morphological research agendas of Giuseppe Colosi and Giuseppe Levi. These biologists sought to understand form’s inner composition and structure. First, I will briefly outline the morphological practices and frameworks used to study form changes and structures in the (...) early twentieth century. Second, I will discuss what the Italian biologist Antonio Pensa called the morphological problem. Third, I will examine Colosi’s response to the morphological problem. Fourth, I will analyze Levi’s morphological research program. As a result, this paper paves the way for a more nuanced and varied picture of the so-called “organicism movement” in the first half of the twentieth century by calling attention to morphology as practiced in Italian-speaking biology. In fact, alongside dialectical materialism and holistic biology, two of the main strands within organicism, the architectural approach to evolution as practiced in Italy and elsewhere had a profound impact on twentieth- and twenty-first-century organicism specifically and on evolutionary biology generally.
