In the corpus of phenomenological philosophy (as far as it is influenced by the works of Jacob von Uexküll and the debate of phenomenologists with philosophical anthropologists such as E. Cassirer, F. J. J. Buytendijk, and A. Portmann), we find the allegation that one of the fundamental differences between human and non-human animals is that while the non-human animal has a species-specific umwelt, humans have access to (a certain idea of) welt. In this sense, Heidegger speaks of the animal as (...) a being “poor-in-world” in contrast to man as a “world-making” being. Similarly, Merleau-Ponty states that language helps a human person step out of her umwelt into the idea of welt. In the present study, I proceed from the critical reflection of this umwelt–welt distinction, emphasizing the question of the status of this “world.” For a better understanding of this problem, I illustrate it by the example of sign language acquisition by congenitally deafblind people, using phenomenological analysis of intercorporeality and associated phenomena in combination with “dialogical epistemology” as an interpretive framework. Claude Romano’s thesis of “evential hermeneutics” can illuminate this situation, as it explains the vital role various events play in establishing the world through our experience. From this point of view, the “world” plays a role not as a sum of objects in a play of objective causes, but rather it is a transcendental field from which events arise. (shrink)

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)

Kurt Goldstein’s thinking on health and disease is based on the concept of milieu [Umwelt], which he inherited from the ethologist Jacob von Uexküll, while at the same time reforming the concept in an original way. Goldstein’s interpretation of the organism-environment relationship emphasises the dynamic nature of this relationship and the reciprocal structuring of the two poles; this hypothesis forms the basis of his original conception of pathology as the shrinking of the patient’s environment. The German neurologist’s position is characterized (...) by the ambivalence that runs through his conceptions of pathology and health, and which gives his thought its richness. On the one hand, ordered behaviour is a necessary condition for the patient’s adaptation to a new relationship with the environment, but it may also be pathogenic if it is aimed at self-preservation only. On the other hand, according to Goldstein, health is, in a first sense, a tendency of the organism to actualise its own capacities, even in a situation of illness; in the second sense, it is a tendency towards expansion and self-actualization that goes beyond the aim of constituting an adequate environment for the organism.
