内格尔作为意识经验问题的理论先驱之一,其思想虽屡被提及,但仍有进一步深入挖掘和讨论的广阔空间,特别是其“双面理论”。内格尔关于主客、身心的双面理论重点论述了主观的心灵何以位于客观的物理之中,对此他主张一个单一的事物能同时拥有物理和心灵两种互不还原的本质特征。但与此同时,该理论不可避免地陷入了泛心论的困境,并难以确保意识的统一性。不过内格尔并没有因此否认其理论构想,他指出心灵与物理很有可能在某种更深层次的理论中得到非还原的统一描述,这是其意识理论的最终指向。
As one of the forerunners of the theory of consciousness experience, Nagel’s thought has been mentioned repeatedly, but there is still room for further digging and discussion, especially its double-sided theory. Nagel’s two-sided theory of subject and object, body and mind focuses on why the subjective mind lies in the objective physics. To this end, he advocates that a single thing can possess both physical and spiritual essential features that are independent of each other. At the same time, however, the theory inevitably plunges into the plight of pan-pondering and fails to ensure the unity of consciousness. However, Nagel did not deny its theoretical conception. He pointed out that psychology and physics are likely to obtain a non-reductive unified description in some deeper theory, which is the ultimate point of his theory of consciousness.
