Abstract: As a famous American social philosopher of the 20th century, George Herbert Meads linguistic theory broke a new path for language sociology study. Mead regards language as a social semiotic and social organization principle and considers that language makes social individuals possess a complete self, and then using the communication function of speech act will link up individual in society. Language communication makes society as a whole process into the individual experience, and makes human social communication rationality possible.

Key words: George Herbert Mead, language semiotic, purpose rationality, communication rationality

摘要： 作为20世纪美国著名的社会哲学家，米德的语言符号理论开辟了语言研究的社会学转向，米德将语言看作是一种社会符号和社会组织原则。米德认为语言的产生使得社会个体拥有了完整的自我，进而运用言语行为的交往功能将社会中的个体连结起来。语言交往使得整个社会过程进入个体的经验之中，使人类的社会交往理性成为可能。
