Despite the change of his thoughts during his lifetime, Wittgenstein was always concerned about the standard and the boundary
of language. His early schema theory later gave way to the theories of tools and games, which set the foundation for language philosophers who research into the theory of
speech acts. Wittgenstein compared language to a carpenter's kit of tools, each of which has its own function and requires specific techniques for handling. He also compared language to various games, each with its own rules and standards. Moreover, he thought endless new tools and games could be added if they were necessary and creative. These ideas greatly enlightened Austine and Searle who proposed their own speech act theories and
language rules. The pioneers of speech act theories have put forward their own concepts of language rules regarding how to utilize language, how to interpret the relationship between meaning and language use. This paper is intended to present a panoramic view of language rules behind speech act theories, a new perspective to contemporary western language philosophy, by integrating Wittgenstein's philosophical ideas of language with speech act theories.
