超越弗雷格的“第三域”神话

<正>如达米特所指出的:"弗雷格关于思想及其构成涵义的看法是神话式的。这些恒久不变的实体居住在‘第三域’(the third realm),后者既不同于物理世界,也不同于任何经验主体的内心世界……。

Beyond Frege’s Myth of "the Third Realm"

This paper critically examines Frege’s anti-psychologism,and reaches the following conclusions:(1) Frege’s theory of thought is internally inconsistent:a thought cannot be the sense of a sentence and also be prior to language,and even independent of human thinking and mind.(2) The theory has to face many problems difficult or even impossible to solve,e.g.how do we grasp a thought? How do we determine whether a thought is true or false? How can we identify the sameness of thoughts? How can we make clear the complicate relations among the objects of the third realm?(3) It is the source of all the troubles with the theory that Frege implicitly holds that there are only two extremes,i.e.a pure and complete subjectivity and a pure and complete objectivity,and lacks an intermediate category of inter-subjectivity to be the bridge from pure objectivity to pure subjectivity.Finally,this paper develops an alternative theory of thought resulting from the revision of Frege’s theory of thought.
