Abstract: Wittgenstein claims that the essence of philosophy can only be found in the language， and whether they should be terms or sentences， their function is not only to refer to the external objects and facts， but also to attempt to weave life scenes. Wittgenstein's thoughts of holistic experience， functional semantics and context have laid a solid foundation of dialectical philosophy for the functional semantics established by Halliday and other scholars. The philosophical trace of functional semantics is explored， and the inheritance and transcendence of Wittgenstein's philosophy is expounded. A new understanding and examination of form and meaning fusion and an exploration of the nature of semantics from the perspective of humanism are of great philosophical significance to functional linguistics research.

Key words: Wittgenstein, functionalist semantics, humanism, meaning and form
