Umwelt

Biological foundations central to the study of communication and signification

In the semiotic theories of Jakob von Uexküll and Thomas Sebeok, umwelt is the "biological foundations that lie at the very center of the study of both communication and signification in the human [and non-human] animal". The term is usually translated as "self-centered world". Uexküll theorised that organisms can have different umwelten, even though they share the same environment. The term umwelt, together with companion terms Umgebung and Innenwelt, have special relevance for cognitive philosophers, roboticists and cyberneticians because they offer a potential solution to the conundrum of the infinite regress of the Cartesian Theater.
