In this paper, I draw a parallel between aspects of René Thom’s topological program understood as semiophysics, and Jakob von Uexküll’s theory of meaning. Through the use of Thom’s semiophysics, I believe that it is possible to interpret Uexküll’s intuition that meaning unfolds a kind of transformation in an organism’s transactions with the environment: that is, meaning incorporates topological spaces. The central idea in question is that beyond the semantic, syntactical and pragmatic human use of language, meaning incorporates specific topologies (...) by expressing the spatial interaction between organism and environment. This is what I mean by René Thom’s reading of Jakob von Uexküll. (shrink)
