Uexküll’s 1917 critique of what he calls the “English morality”, written during World War I, points the contemporary reader toward important implications of the translation of descriptive scientific models to normative ethical theories. A key figure motivating biosemiotics, Uexküll presents here a darker side: one where his Umwelt theory seems to motivate a bio-cultural hierarchy of value and worth, where some human beings are worth more than others precisely because of the constraints of their Umwelten. The first English translation of (...) this essay, introduced here, gives scholars access to Uexküll’s lines of thought, historical context, and normative interpretations. It is particularly pertinent for contemporary attempts to develop a biosemiotic ethics based, among other things, on the Umwelt theory. (shrink)
