This three-volume paperback edition makes the key texts of a classic in sign theory newly accessible. The philosophical semiotics developed by Charles Sanders Peirce not only replaces epistemology; rather, it forms the foundation of a philosophical system that undertakes a comprehensive synthesis of the major philosophical traditions of antiquity, the Middle Ages, German idealism, and logic in a theory of all forms of representation. The three-volume edition of the semiotic writings provides an overview of the entire development of Peirce's semiotics from 1859 to 1912.
