Jakob von Uexküll and Philosophy: Life, Environments, Anthropology

Abstract

Jakob von Uexküll (1864–1944) was a biologist, but the impact of his work has been perhaps stronger and more persistent in philosophy and the humanities than in the natural sciences. As one of the contributors to this book observes, Uexküll's conception of biology is “more at home among the disciplines composing the Geisteswissenschaften [humanities] than those included in the Naturwissenschaften [sciences], insofar as Uexküll's biology put Verstehen [understanding] before Erklären [explaining].” Uexküll began his career as an experimentalist of a “proto-behaviorist” kind but came rapidly to be dissatisfied with the reduction of physiology to action-and-reaction chains. He argued that the animal-as-machine, the model that lies behind behaviorism, cannot be the starting point of biology. The relation between cause and effect in a machine is direct: the wings of a windmill, say, transfer their movement to a cog even if no one is there to perceive the transfer. In contrast, in the realm of the living, “a stimulus must be ‘noticed’ by a subject” to have any effect. Thus, Uexküll claims, “the first task of [the biologist] consists in seeking out the animal's perception signs”—in searching for what, in its surroundings, an animal perceives and of what it takes notice.Uexküll defined surroundings (Umgebung) as the whole physical reality in the vicinity of an animal, whereas by the term environment (Umwelt) he meant only that part of an animal's surroundings that it perceives. Given Uexküll's understanding of biology as the study of signs of perception (Merkmale), it is no surprise that his work has been a crucial source of inspiration for semiotics. Only one chapter of this new book is devoted to that topic, since Uexküll's presence in the field of semiotics (and in biosemiotics more particularly) is already well documented and analyzed in many publications, whereas his impact on the field of philosophy has been less studied (Brett Buchanan's Onto-Ethologies is, to date, perhaps the best study of that kind). Martin Heidegger was not the first to import the Umwelt theory into philosophy (Max Scheller, Helmuth Plessner, and Ernst Cassirer did so before him, and to each of them a chapter is devoted), but Heidegger is the most famous. It was by reworking an example of Uexküll's—“the rock on which the lizard lies is not given to the lizard as rock, in such a way that it could inquire into its mineralogical constitution for example”—that Heidegger characterized the divergent ways in which animals and humans approach the world. The former can use the things of the world, but humans are uniquely capable of conceiving things as independent of their use of them. We have no more direct access to our physical surroundings than other animals do, but, Heidegger held, we are at least able to imagine our surroundings and the things that fill them as independent of us (and eventually to examine them in the way that a mineralogist examines stones).Thus, Heidegger used Uexküll to set out an “ontological difference” between humans and animals. Gilles Deleuze, on the other hand, made use of Uexküll to advance a nondualistic ontology in which “the affects [that animals] are capable of” is given as the definition of bodies—a definition, he emphasized, “no less valid for us, for humans, than for animals.” Other philosophers whose understanding and use of Uexküll are examined in detail include Maurice Merleau-Ponty, Georges Canguilhem, Hans Blumenberg, and Giorgio Agamben; in addition to the complementary chapter on Uexküll and semiotics, already mentioned, there is one on his place in hermeneutics and one on the influence of Kant. The final chapter concerns the remaking of Uexküll by artists. In this way, this collection of studies offers a varied, detailed, well-structured, and engaging presentation of one of the most original biologists of the last century. As a whole, this book is an example of philosophy at its best—which is: when it specifies, pluralizes, and intensifies the thoughts and works of others.
