Abstract

Biosmiotics is trying to extend semiotic concepts to biological phenomena and demarcate the biological sphere from the non-biological sphere using the applicability or inapplicability of semiotics as the demarcation criterion. We could call it antireductionsit in the first part of its enterprise as the world of life is interpreted in quasi-human terms; and we coulld call it reductionist in the second part of its enterprise as, for example, causality is excluded from the semiotic sphere. This article promotes a view according to which applicability of semiotic concepts cannot serve as a demarcation criterion to partition reality plainly because the extensions of the concepts of semiosis, cogntion, subjectivity, and -- surprisingly -- causality, coincide. Both positive and negative lessons will be taken from Jakob von Uexküll's ideas by both developing and criticizing them
