本篇論文的主旨在於否證「強義人類中心主義」與「非人類中心主義」,並且指出,相較於前二者,「弱義人類中心主義」才是一套較為完善的環境倫理學系統。 本篇論文由 Norton 的人類中心主義理論作為參考系,涵蓋了以下的重點:(1) 人類中心主義的定義:由諸多歧異的字詞與諸學者的定義,釐清三種不同的人類中心主義;(2) 「強義人類中心主義」的理論錯誤之處:由非人類中心主義學者的理論來否證「強義人類中心主義」;(3) 「非人類中心主義的理論」錯誤之處:指出非人類中心主義理論與其立場的錯誤之處;(4) 為何我們應該選用「弱義人類中心主義」:說明為何「弱義人類中心主義」是一套較為完善的環境倫理學。 The main thrust of the thesis that is to refute “strong anthropocentrism” and “non-anthropocentrism”, and that indicate “weak anthropocentrism” is a better approach in the environmental ethic. This thesis that it takes the opportunity to Norton‟s Anthropocentrism as a framework, deals with four issues. First, to define two kinds of Anthropocentrisms, I attempt to discuss the different definition between researchers. Besides, I would take the thesis of “non-anthropocentrism “ to refute “strong anthropocentrism”. Thirdly, I would point out there are some mistakes in thesis of “non-anthropocentrism “. Finally, I will explain why we should exercise “weak anthropocentrism” as a complete environmental perspective.
