A Foray into the Worlds of Animals and Humans ─ With a Theory of Meaning

"At One and the Same Time Jakob Von Uexkull is a Kind of Biologist Shaman Attempting to Cross the Rubicon to Nonhuman Minds, and A Humble Naturalist Closely Observing and Recording His Fellow Living Beings."---Dorion Sagan, From the Introduction

"The pioneering biophilosopher Jakob von Uexkull (1864-1944) embarks on a remarkable exploration of the unique social and physical environments that individual animal species, as well as individuals within species, build and inhabit. This concept of the Umwelt has become enormously important within posthumanist philosophy, influencing such figures as Heidegger, Merleau-Ponty, Deleuze and Guattari, and, most recently, Giorgio Agamben, who has called Uexkull "a high point of modern antihumanism."

A key document in the genealogy of posthumanist thought, A Foray Into the Worlds of Animals and Humans advances Uexkull's revolutionary belief that nonhuman perceptions must be accounted for in any biology worth its name. It also contains his arguments against natural selection as an adequated explanation for the present orientation of a species' morphology and behavior. A Theory of meaning extends his thinking on the Umwelt, while also identifying an overarching and perceptible unity in nature.

Jakob Von Uexkoll Was Born in Estonia and Educated at the University of Heidelberg and the Zoological Center in Naples. In 1926 he Founded the Institute for Environmental Research at the University of Hamburg.
