This Companion offers an original new account of Ferdinand de Saussure, widely considered to be the founder of modern Linguistics as well as Structuralism. In addition to looking at his pioneering Course in General Linguistics, contributors consider his lesser-known early work, more recently-discovered manuscripts, and influence on other disciplines such as cultural studies, philosophy, literature and semiotics. With contributions by specialists in each field, this comprehensive guide creates a unique picture of the lasting importance of Saussure's thought.
