當玄學家把抽象的名理變成清談的課題時，言意之辨就成了主要的論題。王弼結合《周易‧繫辭》的“言不盡意”和《莊子‧外物》的“得意忘言”之說，首倡“言意之辨”的論題，雖是為了解《易》，卻開創了一套有系統的玄學理論，對當時及後世都產生了不少影響。然而“言”究竟能不能盡“意”？這牽涉到幾個問題，首先是王弼的學術淵源何在？其次是王弼的“意”究竟為何？再則是王弼是如何解決“言意”之間的困境？最後是他的論述又如何建構一套玄學方法論？這些都將與儒釋道的形上義理有著深厚的關係，本文就從這幾個問題來說明王弼“言意之辨”的思想體系。 “The Distinction of Language (Yen) and Significance (Yi )”became the main theme while abstract forming trunk stream in Wei-chin dynasty.
