Umwelt

An umwelt (plural: umwelten; from the German Umwelt meaning "environment" or "surroundings") is the specific way organisms of a particular species experience the world, which is dependant on what their sensory organs and perceptual systems can detect and interpret.[1] In the semiotic theories of Jakob von Uexkull and Thomas Sebeok, it is considered to be 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".[3] Uexküll theorised that organisms can have different umwelten, even though they share the same environment. The term umwelt, together with companion terms Umgebung (an Umwelt as seen by another observer) and Innenwelt (the mapping of the self to the world of objects),[4] 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. https://en.wikipedia.org/wiki/Umwelt
