弗雷格一生在学术上的终极关切,是如何在方法的层面上,推进科学的进步。弗雷格讨论问题的方式,始终从语言的角度出发,区分了专名、概念词和句子之间的差异,并提出了句子为先的重要思想。在其著名的逻辑主义研究纲领中,弗雷格首先指出,一定要将主观的东西和客观的东西区别开来。但弗雷格所谓的主客之别,并非传统意义上的简单二分,而是三分:表象、涵义和意谓。在如上思想的基础之上,弗雷格对科学与艺术、真与美的关系进行了系统、深入的比较研究。
Frech’s life in the academic ultimate concern is how to promote the scientific progress at the method level. Frege ’s way of discussing the issue always distinguishes the differences between proper names, concept words and sentences from the linguistic point of view, and puts forward the important idea of first sentence. In his famous research program of logicism, Frege first pointed out that we must distinguish the subjective things from the objective things. However, Frege’s so-called difference between subject and object is not a simple dichotomy but a third in the traditional sense: appearance, meaning and meaning. Based on the above ideas, Frege conducted a systematic and in-depth comparative study of the relationship between science and art, truth and beauty.
