叔本华将康德的“自在之物”原创性地解读为他的“意志” ,发动了西方哲学史上又一场哥白尼式的革命 :传统意义上“意志”作为一个哲学概念一直是主体性的和隶属于现象界的 ,从未有人将其尊为终极的本体 ;叔本华大胆地向这一约定俗成的语义挑战 ,将一个主体的和现象的意志擢升为客体性的和本体性的自在意志。本文展示了叔本华的意志本体论的创建方式 ,即从“身体”出发对自在意志的追询策略 ,为理解其整个哲学体系提供了一个思路 Schopenhauer’s original interpretation of Kant’s “things of freedom” as his “will” has launched yet another Copernican revolution in the history of western philosophy: as a philosophical concept, “will” has always been the main body Sexuality and belonging to the phenomenal world have never been respected as the ultimate noumenon; Schopenhauer boldly challenged this conventional semantic challenge by elevating the will of the subject and the phenomenon to the objective and the noumenal Free will.
