2、philosophy were praised classics, such as his masterpiece “On sense and reference” that was praised as a model of analytic philosophy. In this highly imaginative paper, Frege proposed the identity statements puzzle, that

3、 people still suffering, and was one of the three major problems that were intituled by Russell. It was named as Frege’s puzzle by scholars. The puzzle involved the identity relationship and the cognitive variance, but a

5、B for the cognitive value greater than A=A? Frege distinguished the sense and reference of a name strictly, that was a tool for eliminating and the start of his trip. First, he opined that the identity statement expresse

6、d the sense relationship between symbols. In his view, the “identity” or “equivalent” is not meant to convey the reference relationship between symbols. Because it is very evident that, because A, B meant the same, and i

7、f the “identity” is the reference relationship between symbols, then it can’t explain the cognitive value variance between A=A and A=B. Frege pointed that, when we inspected the cognitive value of a symbol, not only to t

8、he reference but should also consider the sense. Because the sense is related to ours cognition. So he concluded: It is the different sense of symbols led to the cognitive value variance between A=A and A=B. Frege’s meth

10、egardless of how creative thinking and regardless of how clever answer program of Frege, for the puzzle itself on the identity statements, he was a loser. His failure was that he overly dependent on the sense of symbols,

11、 and neglected the analysis of the “identity” itself. Based on the latest answer from both at home and abroad, we rethink the identity statements puzzle. We believe that shouldn’t paranoid on the sense of symbols, but sh
