In the discussion about the ”distinction between speech and meaning,” the metaphysicians sorted out the two methods-”analyses and distinctions” along with ”obtaining meaning while forgetting speech”-to address the problems with Confucian Classics of the Han Dynasties and in turn to construct a doctrinal system. Among the metaphysicians' ideas, the most notable one is definitely Wang Bi's concept of speech and meaning. Wang not only expressed his ideas about speech, image, and meaning, but also proposed the metaphysical methods of ”analyses and distinctions” along with ”obtaining meaning while forgetting speech”; he applied these methods to his commentaries of Confucian Classics, which were generally accepted and utilized by later metaphysicians. In view of the importance of Wang Bi's concept of speech and meaning, this paper is to discuss three main sections: first, inquiring the possible implications of speech, image and meaning as well as the relationships between them; second, reviewing Wang Bi's concept of speech and meaning by means of the ”distinction between speech and meaning” along with the two perspectives of metaphysical methodology; and finally, making a general statement about the significance and influence of Wang's concept of speech and meaning and discussing its possible limits.
