Abstract
I aim to demonstrate the pivotal roll of dialogism in semiosis in addition to modeling and communication. The concept of communication is an old one in semiotics. Semiology considered it as central. It was associated with information in the conceptionof sign proposed by “semiotics of communication”, by contrast with Peircean and Morrisian “semiotics of interpretation”. More recently, another central concept has been added in semiotics by the Moscow-Tartu school: modeling, later reinterpreted by Thomas A. Sebeok in the context of his “semiotics of life” or “global semiotics”. In this paper I propose dialogism as a third fundamental concept with modeling and communication in the study of signs oriented in the direction of semiotics of interpretation.
