This work presents the first systemic account of the author's innovative theory of semiotic phenomenology and its place in the philosophy of communication and language. The creative and compelling project presented here spans more than fifteen years of systematic eidetic and empirical research into questions of human communication. Using the thematics of Merleau-Ponty's existential phenomenology, the author explores the concepts and practices of the human sciences that are grounded in communication theory, information theory, language, logic, linguistics, and semiotics. The hermeneutic discussion ranges over contemporary theories that include Roman Jakobson's phenomenological structuralism, the semiotics of Umberto Eco, Charles Pierce, and Alfred Schutz, the theory of speech acts offered by Jurgen Habermas and John Searle, and Michel Foucault's phenomenological rhetoric of discourse. In general, this highly developed study offers the reader a fresh account of the problematic issues in the philosophy of communication. It is a work that any scholar in communication, philosophy, linguistics, or social theory would welcome for its scope and sustained research.
