"The fundamental significance of the work of Charles William Morris is based on the fact that he was a philosopher in the widest sense of the term, a man who changed the world, leaving it a different place than it had been before. Morris left behind a large number of writings, but not all have been made available, and the breadth of his work as a whole has gone unrecognized. His contributions to sign theory have gained a firm foothold in international semiotic discourse, but his axiological studies as well as his work on the theory and history of science have largely been ignored, as have his writings on the subject of mind and his essay on the various paths of life."
