本文是要檢討海德格與高達美的時間概念，說明它與他們哲學的關係。我要指出，無論海德格前期和後期的時間概念，在理論上無法讓海德格完成他的哲學工作──存有意義的探索，但高達美的時間概念，卻可以讓他得以詮釋存有的意義。

This essay analyzes the concept of time in the philosophy of Heidegger and Gadamer in order to show its relationship with both philosophers’ discussion on “Being”. I point out that no matter in his early or later writings, Heidegger’s concept of time is in conflict with his concept of understanding. Therefore, Heidegger’s quest for the meaning of Being cannot be accomplished. In contrast the Gadamerian concept of time makes the understanding of the meaning of Being possible.
