At the turn of 1960s and 1970s, Stanisław Lem devoted some of his non-fiction writing to a discussion and considerations of semiotics. Most of them were expressions of a critical approach mainly directed against structuralism. However, Lem also formulated some positive statements although they were not developed systematically. The article offers an analysis of Lem’s semiotic ideas from the perspective of semiotic functionalism of Jerzy Pelc, mainly considering its two main components: contextualism and typological approach. Special attention is paid to (...) the latter because both Pelc and Lem proposed some original solutions in this respect. What is meant here is the multidimensional typology of symbolic uses of signs developed by Pelc and Lem’s multidimensional typology of the situations of the reception of texts. Although they are independent form each other, these proposals show some convergence both in their ways of construction and roles they are supposed to perform. Henceforth, one can say that Lem was a crypto-functionalist. (shrink)
