非衍生内容存在性问题剖析

非衍生内容之争由来已久，但是争论双方都存在着或多或少的缺陷。亚当斯等人并没有给出有效的反驳；福多错误地解释了对立关系，把对立关系解释为因果关系；同构理论只能保证 X 和‘X’之间存在映射上的可能性，而不能保证其必然性；丹尼特把自然选择过程看作是意向性过程存在明显的错误，而克拉克的反驳却最终走向了妥协。事实上，非衍生内容作为认知的标志并不合理，并没有设立的必要。

An Analysis on the Existence Problems of Non-derivative Content

The debate on non-derivative content has been a long-lasting issue,but there are more or less defects. Philosophers,such as Adams,have never reached fruitful contradiction;Fodor`s wrongly interpreted the opposite rela-tionship as a kind of causal relationship.The isomorphism theory can only guarantee the possibility but the inevitabili-ty of mapping between X and'X';it is obviously wrong for Dennett to regard natural selection process as an intention one,but Clarke's contradict ends in compromise.As a matter a fact,it is unreasonable as well as unnecessary to see derivative content as a symbol of cognition.
