ArgumentThis article focuses on a problematic character of communication in science. Two solutions are compared: paradigm-based science and the semiotic solution developed in the arts and social sciences. There are several parallels between the latter approach and Marxist dialectics. A third, original, approach to solving communication problems is proposed; it can be labeled “transactional.” It represents a version of the semiotic solution with particular emphasis on interactions, both face-to-face and depersonalized, and the imperative of negotiating and finding compromises. Communication problems (...) existing at two registers of interactions, face-to-face and depersonalized, are differentiated; freedom is interpreted as the capacity to change the registers at will. An in-depth case study of the Coase theorem in economic sciences and legal studies illustrates key points in the proposed analysis. (shrink)
