本文旨在透過人的道德實踐論述人的生命意義。首先，本文始於反省批判當代文化的「自我中心」基調，指出人的行動之基本特質；然後，透過反思人的道德實踐以反思人追索並體現生命意義的方式。很顯然，人並不滿足於單單存在，而力圖追求有意義的存在，因而「生命的意義為何」以及「如何追索並體現生命的意義」即成為人的生命本身的根本問題與任務。對此，本文相反於當代文化潛在的「怨恨道德」趨勢，而認為「道德」是最能影響生命命意義的人的獨特現象；據此，主張人的道德實踐不唯關於如何行動，其實更關乎生命意義的體現。本文認為作為一個渴望不死但又必死的人，我們的生命意義即體現在不止息地向著至善之奮鬥中。

　　　　　This article begins with criticizing the "self-centred" direction of modern culture, then disclosing the basic properties of human action; thereby, through reflecting moral praxis, it reflects the way by which we can seek and embody the meaning of life. Obviously, We, as human being, do not satisfy with mere existence, but strive to seek a meaningful existence. Therefore, "What is the meaning of life?" and "how to week and embody the meaning of life?" become the main question and task in our life. Conversing the "ressentiment of morality" implied in modern culture, this article strongly insists that morality is sui generis and is the best place of manifesting the meaning of our life, and, accordingly, that the morality is not only regarding how to act, but regarding the embodiment o meaning of life. Therefore, this article claims that we , human being, as a mortal life but longing for eternity, the meaning of our life are revealed in the endless effort toward summum bonum.
