Wittgenstein's philosophy is directly related to semiotic theory. To examine this critical question, Wittgenstein & Semiotics discusses the cultural climate of Wittgenstein's semiotics as the influence of Saussure and Peirce. Wittgenstein's word-play can reflect historically the pros and cons of modern society transfigurating the disasters of two World Wars into belief and action. But Wittgenstein's polemical style reflects the Zeitgeist of a new structure of writing philosophy based on the special force of semiotics. By transmitting one message to another to see how the linguistic signs are decoded and interpreted, Wittgenstein saw how the exchanges of signs are carried out to renew cultural society. His linguistic sign functions in direct speech reflect how the structure of signs influences the symbolic systems and processes to communicate the meaning of his style to the readers. Wittgenstein's theory of semiotics contributed to the cultural technique of the growth of interdisciplinary fields of scholarly disciplines, both humanistic and scientific, which Wittgenstein's "free" speech enjoys today.
