Abstract

Frege believes that the real power to determine the sentence to show the logic of interest to "true." And with the word "truth" of redundancy on the same, he believes the lack of everyday language and the ability to determine the appropriate symbol. However, Frege, it seems that he invented the concept of text assigned to a special force to determine the sign: determine the bar. This paper attempts to demonstrate, although Frege until the final stage of his academic career to determine the bar still insist to retain its logic into the language system, but the concepts and words in this design does not meet him on the relationship between logic and fuzzy real insight. A key step in the argument, we will by means of Husserl on the "faith of variation" to clarify the doctrine of "judge" and "determined" by Frege between the neglected difference. On this basis, we finally prompted a brief on the logic of Frege and true insight into the relationship between the interpretation of ambiguous direction
