their environment(s). He argued that organisms experience life in terms of species-specific, spatio-temporal, "self-in-world" subjective reference frames that he called ''Umwelt'' (translated as ''surrounding-world'', ''phenomenal world'',Jakob von Uexküll, ''A Stroll Through the Worlds of Animals and Men: A Picture Book of Invisible Worlds''. In ''Instinctive Behavior: The Development of a Modern Concept'', edited and translated by Claire H. Schiller, New York: International Universities Press, p. 5. ''self-world'', ''environment'' - lit. German ''environment''). These ''Umwelten'' (plural of ''Umwelt'') are distinctive from what Uexküll termed the " Umgebung" which would be the living being's surroundings as seen from the likewise peculiar perspective or ''Umwelt'' of the human observer. ''Umwelt'' may thus be defined as the perceptual world in which an organism exists and acts as a subject. By studying how the senses of various organisms like

work, he was able to build theories of how they experience the world. Because all organisms perceive and react to sensory data as signs, Uexküll argued that they were to be considered as living subjects. This argument was the basis for his biological theory in which the characteristics of biological existence ("life") could not simply be described as a sum of its non-organic parts, but had to be described as subject and a part of a sign system. The biosemiotic turn in Jakob von Uexküll's analysis occurs in his discussion of the animal's relationship with its environment. The ''Umwelt'' is for him an environment-world which is (according to
Giorgio Agamben Giorgio Agamben ( ; ; born 22 April 1942) is an Italian philosopher best known for his work investigating the concepts of the state of exception, form-of-life (borrowed from Ludwig Wittgenstein) and '' homo sacer''. The concept of biopolitic ...
), "constituted by a more or less broad series of elements alled"carriers of significance" or "marks" which are the only things that interest the animal". Agamben goes on to paraphrase one example from Uexküll's discussion of a tick, saying,
"...this eyeless animal finds the way to her watchpoint t the top of a tall blade of grasswith the help of only its skin's general sensitivity to light. The approach of her prey becomes apparent to this blind and deaf bandit only through her sense of smell. The odor of butyric acid, which emanates from the sebaceous follicles of all mammals, works on the tick as a signal that causes her to abandon her post (on top of the blade of grass/bush) and fall blindly downward toward her prey. If she is fortunate enough to fall on something warm (which she perceives by means of an organ sensible to a precise temperature) then she has attained her prey, the warm-blooded animal, and thereafter needs only the help of her sense of touch to find the least hairy spot possible and embed herself up to her head in the cutaneous tissue of her prey. She can now slowly suck up a stream of warm blood."
Thus, for the tick, the ''Umwelt'' is reduced to only three (biosemiotic) carriers of significance: (1) The

Theoretical biology

Uexküll anticipated many computer science ideas, particularly in the field of robotics, roughly 25 years before these things were invented. Uexküll views organisms in terms of information processing. He argues every organism has an outer boundary which defines an Umwelt (German word generally meaning "environment", "surrounding world"). Rather than the general meaning, Uexküll's concept draws on the literal meaning of the German word, which is "surround-world", to define the Umwelt as the subjectively perceived surroundings about which information is available to an organism through its senses. This is a subjective ''Weltanschauung'', or "world view", and is therefore fundamentally different from the

concept, which is derived from the objective Newtonian viewpoint. The organism has sensors that report the state of the ''Umwelt'' and effectors that can change parts of the ''Umwelt''. He distinguished the effector as the logical opposite of the sensor, or sense organ. Sensors and effectors are linked in a
feedback loop Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause and effect that forms a circuit or loop. The system can then be said to ''feed back'' into itself. The notion of cause-and-effect has to be handle ...
. Sensor input is processed by a ''Merkorgan'' and effectors are controlled by a ''Werkorgan''. The modern term "sensorimotor" used in enactive theories of cognition encompasses these concepts. He further distinguishes the ''Umgebung'' (that part of the ''Umwelt'' that represents distal features of the external world, in German "that which is being given as surroundings") from the Innenwelt which is reported directly by sensors and is therefore the only unmediated reality immediately knowable to the organism. The relationship between the distal (mediated, transformed) features of the Umgebung and the proximal (untransformed, unmediated, primal) features of the Innenwelt must be learned by the organism in infancy. The nature of the Umgebung::Innenwelt relationship is relevant to the later theories of

but derived logically from the properties of the sensors. What we now call a "feedback loop" he calls a "function-circle" and "circle" seems to be something like "system". He uses the term "melody" to mean something close to "algorithm". He coins around 75 technical terms, and a proper understanding of his book would require clearly defining them in modern terms and understanding their relations. He notices

. This committee was to accompany the National Socialist program with a philosophy of law appropriate to "Germanness." In doing so, Uexküll did not merely seek a connection to National Socialism, but actively participated in the collaborative elaboration of a National Socialist philosophy of law and attempted to substantiate it through his conception of Umwelt. Uexküll's doctrine led to a holistically based rejection of democracy and discharged itself in an identitarian logic in which everything is in its place according to plan and that which is in the wrong place should disappear. As late as 1933 Uexküll held hopes that the rise of Hitler to power might bring an end to the expansion of communism and the democratization of German society, for which he had an aristocratic antipathy, but his expectations were met with disappointment. In May of the same year Uexküll wrote a letter to Eva Wagner Chamberlain, daughter of Richard Wagner, and wife of his late friend
Houston Stewart Chamberlain Houston Stewart Chamberlain (; 9 September 1855 – 9 January 1927) was a British-German-French philosopher who wrote works about political philosophy and natural science. His writing promoted German ethnonationalism, antisemitism, scientific r ...
, lamenting that the ideas of her husband were being used by Nazism to justify the persecution of Jews in Germany, and describing racial discrimination against Jews as "the worst kind of barbarism". By the autumn of 1933, Uexküll evinced disapproval of Nazi policy and ideology, and afterwards tried to avoid political issues, although it sometimes proved impossible. In 1934, Uexküll dedicated his book ''A Foray into the Worlds of Animals and Humans'' to a Jewish fellow researcher Otto Cohnheim, who, in his words, "lost his appointment as a university professor because of racial politics". Following the publication of Sprengers and Schnödls book, there have been discussions about Uexkülls role in the early 1930s. As Sprenger and Schnödl show, there are no reliable historical sources for many of the assumptions that have been used to defend Uexküll. These anecdotes are taken from a biography of Uexküll written by his wife, Gudrun von Uexküll, in 1964. This book defends Uexküll against all accusations, but does not give any reliable sources or references. For example, Carlos Brentari refers to Uexkülls autobiographical book of personal reminiscences, ''Nie geschaute Welten'' (Worlds never seen). Brentari argues that in this book, Uexküll wrote favorably of the Russian Jews and the Baroness Rothschild. He even states that the book officially banned from display in bookshop windows. This assumption has turned out wrong: The book is not listed on any of the National Socialist's lists of banned books. And, contrary to Brentari, Uexküll takes up the idea of the Jews as "parasitic plants" which only grow where they belong. As Sprenger writes: "This rhetoric already holds the germ of the idea that the host must rid itself of this parasite, despite all sympathies he may harbor for individual members of the alien race, and thus end the supposed abuse of his hospitality. It is precisely because the Jewish population is understood as a parasite that it can, in Uexküll's representation, be so easily expelled: transplanted elsewhere, it will be able to live just as well; but there, too, it may also spread parasitically."
