「自然」的概念關聯著道、天、地、人，可以說是通天接地。既抽象又具體， 既普遍又個別。故王弼贊曰：「自然者，無稱之言，窮極之辭」。從牟宗三與林安 梧兩位先生對《老子》「自然」概念的詮釋，更可以對比出他們對道家核心思想 理解的不同。本文針對《老子》「道法自然」一段文字，對比兩先生的「境界」 與「場域」兩種概念，指出牟先生在「主觀境界型態」理解下，「道法自然」轉 變為重在說明「道是自然」，而「自然」是通過修行所達到一個極高的精神境界。 林先生從「場域」的概念來理解自然，自然是在此場域中，一種能夠讓萬物生生 不息的「自發、和諧與調節性的力量及秩序」。本文認為，此種詮釋下的「道法 自然」，在現代社會中，將蘊含更多可開發的實踐方向。
