The article gives an account of life and work of Jakob von Uexk?ll, together with a description of his impact to theoretical biology, behavioural studies, and semiotics. It includes the complete bibliography of Uexk?ll's published works, as well as an extensive list of publications about him.

Semiotics, the body of knowledge developed by study of the action of signs, like every living discipline, depends upon a community of inquirers united through the recognition and adoption of basic principles which establish the ground-concepts and guide-concepts for their ongoing research. These principles, in turn, come to be recognized in the first place through the work of pioneers in the field, workers commonly unrecognized or not fully recognized in their own day, but whose work later becomes foundational as the (...) community of inquirers matures and ‘lays claim to its own’. As semiotics has matured, the work of Jakob von Uexküll in establishing the concept of Umwelt has proven to be just such a pioneering accomplishment for the doctrine of signs, and in this paper I trace out some of the lines of development according to which Uexküll’s concept came to occupy its central place in semiotics today.

Thomas Sebeok attributed it to what he called the ‘wretched’ translation of Uexküll’s Theoretische Biologie (1920) that the notion of Umwelt did not reachthe Anglo-American intellectual community much earlier. There is no doubt that making more of Uexküll’s Umweltlehre available in English will not only furtherthe biosemiotic movement, but also fill a gap in the foundational theoretical canon of semiotics in general. The purpose of this paper is to address issues of terminology and theory translation between Uexküll’s Umweltlehre and current (...) biosemiotics. (shrink)

This paper aims to give an insight into developments that contributed to the significance of the work of Jakob von Uexküll and stresses the importance of his occupation in Hamburg. A biographical survey pays tribute to the implication of the historical pretext and context. A scientific survey describes findings and ideas of Uexküll that proved important for the development of biology and the cognitive sciences. In addition, this paper sets out to reject the common notion that Uexküll’s concepts were (...) ideas of a purely theoretical and philosophical character. It confirms that in fact the central aims of his work were to sustain the empirical method in biology and to give biology a sound epistemological basis. Some examples show how historical and theoretical developments converged at Uexküll’s Institut für Umweltforschung in Hamburg and ignited a productive research activity. (shrink)

In questo lavoro si dimostra che l'opinione comune, secondo cui è Heidegger a introdurre Jacob von Uexküll nel dibattito filosofico è scorretta, in quanto è Scheler, due decenni prima, a scoprire e valorizzare la portata filosofica di Uexküll. -/- Pure la distinzione fra mondo (Welt) e ambiente (Umwelt), come quella fra apertura al mondo e chiusura ambientale, non è introdotta da Heidegger nel 1929 (cfr. l'Introduzione di Marco Mazzeo al testo di Uexküll, Ambienti animali e ambienti umani, p.18 e seg.) (...) ma è già presente in Scheler negli scritti del periodo 1909-1913. (shrink)

Like other sciences, biosemiotics also has its time-honoured archive, consisting, among other things, of writings by those who have been invented and revered as ancestors of the discipline. One such example is Jakob von Uexküll who has been hailed as a precursor of semiotics, developing his theory of “sign” and “meaning” independently of Saussure and Peirce. The juxtaposition of “sign” and “meaning” is revelatory because one can equally legitimately claim Uexküll as a hermeneutician in the same way as others (...) having claimed him as a semiotician. Such a novel temptation can be justified by Uexküll’s prolonged obsession with Sinn and Bedeutung since his first book in 1909. This paper attempts to reconstruct the immediate intellectual horizon of Uexküll’s historicity, a discursive space traversed by his contemporaries Frege and Husserl, in order to see how Uexküll’s discussions of Zeichen and Gegenstand, Sinn and Bedeutung, were informedby other philosophers of language, and to establish Uexküll as a phenomenological hermeneutician in the tradition of Husserl, Heidegger and Gadamer. To forestall and counter possible criticism that hermeneutics is primarily concerned with textual interpretation, while Uexküll is at most an interpreter of animal life, the paper will discuss his unfinished parody of the Platonic dialogue Meno, which is entitled Die ewige Frage: Biologische Variationen über einen platonischen Dialog (1943). It is through such textual practice that one witnesses the emergence of an Uexküll who embodies at once the addressee exercising his understanding of ancient texts as well as the second addresser recoding his explanation to another group of targeted addressees. This textual practice already goes beyond the confines of biology and in fact involves the linguistic pragmatics of rhetoric and speech act. (shrink)

Resumen: En este artículo sostengo que los planteamientos de Jakob von Uexküll constituyen un apoyo científico decisivo para las reflexiones metafísicas de Martin Heidegger sobre el mundo, más allá de lo que el mismo Heidegger reconoce explícitamente. En particular, los estudios de Jakob von Uexküll enfatizan, de mejor manera que el mecanicismo y el vitalismo, la relación que existe entre el medio ambiente y el mundo interior del animal, lo que es fundamental para que Heidegger sostenga en su (...) lección de invierno de 1929 y 1930 que la esencia del animal es el "perturbamiento".: In this paper I argue that the scientific approaches of Jakob von Uexküll crucially support Martin Heidegger's metaphysical reflections about the world, beyond what Heidegger himself explicitly recognized. In particular, Jakob von Uexküll's studies emphasized, better than mechanicism and vitalism, the relationship between the environment and the inner world of the animal, which is crucial for Heidegger to claim in his winter 1929-1930 lessons that the essence of the animal is "disturbance".

El artículo analiza el problema de los mundos humanos a partir del concepto de mundo circundante que J. von Uexküll plantea para pensar la existencia animal. En este sentido, introduce dicho concepto biológico y sus implicancias, reconstruye las interpretaciones y críticas que se le formulan en la antropología filosófica alemana de principios del siglo XX, y defiende la idea según la cual, desde un horizonte arqueológico, habría una oposición correlativa entre el Umwelt biológico y las ideas filosóficas de mundo humano (...) previamente tematizadas.

In the work of Lorenz we find an initial phase of great concordance with Uexkülls theory of animals’ surrounding-world, followed by a progressive distance and by the occurrence of more and more critical statements. The moment of greater cohesion between Lorenz and Uexküll is represented by the work Der Kumpan, which is focused on the concept of companion, functional circles, social Umwelt. The great change in Lorenz’ evaluation of Uexküll is marked by the conference of 1948 Referat über Jakob (...) von Uexküll, where Lorenz highlights the vitalist position of Uexküll. In the works of the years after World War II, the influence of the Estonian Biologist greatly diminishes, even though Lorenz continues to express his admiration for particular studies and concepts of Uexküll. References to Uexküll’s work are less and far in between, while the difference is highlighted between the uexküllian theoretical frame and Lorenz’s one. The two main critical lines of argument developed by Lorenz in this process are the biological and the epistemological one: on the biological side Lorenz heavily criticizes Uexküll’s vitalism and his faith in harmonizing forces and supernatural factors. On the epistemological side, Lorenz, arguing from the point of view of the critical realism, accuses Uexküll of postulating the separateness of all living beings, a separateness which is due to the Kantian idea that every subject of knowledge and action is imprisoned in the transcendental circle of its representations and attitudes.

This article addresses traditional perceptions about photography's position between nature and culture and concomitant schools of thinking focusing pre-dominantly on the photographic image as a form of visual representation. Aiming to develop an alternative perspective it considers a biosemiotic approach and turns to Jakob von Uexküll's model of subjective sentient worlds that critically dissolves the perceived dualism between nature and culture that has also underpinned most theoretical thinking about photography in the past. Today photography is largely embedded into social (...) media platforms and their interlinked digital networks, which holds far-reaching consequences for a medium that in this current form can only be fully understood if it is considered as a form of embodied material practice. Aiming to understand some of the complex manifestations this technical evolution entails the article further considers the relevance of recent non-representational concepts arising out of cognition theory and cultural geography and uses the 'selfie' as a 'theoretical object'.

The reinterpretation of Nature by biology, which will prevail in spite of all obstacles, has brought our thinking closer to antiquity, giving us the chance to reinvigorate our perused terminology with the help of the resources to be found in the thoughts of the greatest minds of mankind. The way to Plato thus being cleared, I perceived the idea to seek enlightenment on pressing biological questions from the great Sage. As means to this end, I chose to make Socrates continue (...) one of his dialogues, with the adjustment of giving him the knowledge of our contemporary biological problems. Thus some kind of interaction between the Ancients and ourselves is created, to our considerable benefit. (shrink)

En el presente artículo se analizan conceptos clave de la obra de Jakob von Uexküll, a partir de la confrontación con el darwinismo mecanicista de principios del siglo XX, al cual, Uexküll contrapone la idea de un mundo viviente de interrelaciones, conformado de acuerdo con un Plan u Orden subyacentes. Pero la cuestión no del todo resuelta para Uexküll, y que aquí será estudiada, es el papel que ha de atribuirse al azar y a la tendencia natural de traspasar (...) los límites. Cuestión que adquiere su mayor significación en el plano humano, siendo el hombre, como es, antiguo actor de la transgresión. The intention of this paper is to analyze the principal concepts in Jakob von Uexkiiltt's work, considering the confrontation with the darwinian mechanism of the beginnings of the XXth Century. In response to it, Uexkülll supports the idea of a living world of interrelations, which is conformed in accordance to a subjacent Plan or Order. But the question analyzed here, and which is not at all solved by Uexkülll, is the roll that should be attributed to chance, or the natural tendency to surpass the limits. A problem that acquires its deepest meaning in the human context, because man is, as we know, an old actor of transgression. (shrink)
