Book excerpt: Examines some of Eco's writings together with secondary sources in order to arrive at a more comprehensive critique of his literary theories and his notions of general semiotics as a cognitive social/cultural practice. Articles on literary semiotics, which comprise the second section, focus primarily on Eco, Peirce, Bakhtin, Greimas, Borges, and Derrida. Part three examines aspects of Eco's fiction.
