With authoritative scholarship Tony Jappy opens the way for a richer understanding of how the philosophy of representation of Charles S. Peirce evolved into his later semiotic systems. A whole life of thinking and writing on Peirce is condensed in the lucid prose of this new book on Peirce's mature understanding of signs.

Jappy's book is a well-grounded, sophisticated, and provocative contribution to determining the range and scope of Peirce's theory of signs. Combining historical nuance, systematic reconstruction and analysis, and felicitous citation of core texts and illustrative examples, it challenges us to confront the problem of the internal unity and power of Peirce's reflections on the logic and classification of signs.

This book by Tony Jappy presents yet another topical contribution to the journey of exploration and understanding through the great semiotic network and its signifying implications. A rigorous Peirce expert, his scholarship is at once brilliant and profound for complexity, clarity in exposition, and critical perspicacity. While rereading and updating interpretations of Peirce's scientific research on signs in conjunction with his philosophy of representation, Jappy proceeds to reveal aspects of human experience unfathomed by most.
