可持續性問題是一個古老且永恆的問題，它是人類的本質問題之一，人之所以存在而不是不存在，正是可持續問題的引申。只是這樣的問題在今日科技文明的發展中，益顯其迫切與嚴峻罷了。我們並不認為一切的問題都能在古典的思想中找到答案，但是，尋求以往的智慧做為參考，卻不失為一有利的上策。因此，本文特別以老子為核心，展示道家思想對可持續性問題之態度與立場。此中，我們先以事實義、操作義、價值義、信仰義，對可持續性問題之哲學意義加以定位。而後，我們以周文疲弊之回應，說明先秦諸子對可持續性問題之重視，進而再以自然和諧與永續之信念，詳細說明老子思想對可持續性問題的觀點與內容。最後，再以可持續性如何可能為題，提出筆者的初步結論與建議。

Continuousness is an ancient and forever problem. It's one of human essential problems. The reason human is being but nonbeing just the amplification of continuousness. Under the compression of today's technological civics, this kind of problem is more and more serious and harsh. We don't think everything could be solved in classic thoughts; however, it's still an advantageous way to take ancient wisdoms as references. Therefore, focus on Lao-zi, in this paper, I'd like to express the attitude and position of continuousness of Taoism. Within it, I'll position the philosophical meaning of continuousness and then react by the malady of the Chou cultures to comment scholars' emphasis on continuousness. Furthermore, with the conviction of harmony and continuouosness, I'll describe in detail Lao-zi's opinions about continuousness. Last, I'll make a basic conclusion and suggestions of how could it be possible of continuousness.
