The paper deals with the problem of Peirce’s theory of signs, placing it within the context of modern semiotics (comparing it with Saussurean semiology, in particular), and considers Peirce’s semiotics from the point of view of his theory of categories (phaneroscopy) and in the terms of his classification of signs. The article emphasizes the complicated system of Peirce’s late, “mature”, semeiotic and his theory (classification) of Interpretant.
