弗雷格真之思想及其意义

Frege’s Theory of Truth and Its Significance

在逻辑与哲学的研究中,弗雷格具有独特的求真方法,弗雷格认为,思想是某种对此能够产生真的问题的东西,逻辑研究的出发点是具有真值的思想。围绕这一宗旨,弗雷格构造了一种形式语言,即概念文字,以此来求真,他在建立了形式语言的基础上,完成了演算系统的构成,以此来研究真。在此基础上,弗雷格通过研究句子来研究真。在求真中弗雷格坚持了客观性,语境论及概念和对象区分的三个原则。弗雷格真之思想对于后人逻辑研究方式的转变,当今哲学研究方式的转变以及今后中国传统思维的转变都具有一定的意义。

In the study of logic and philosophy,Frege has a special method of pursuing truth.Frege thinks thought is something on which truth can be produced and the start of logic study is thoughts having truth-value.For this purpose,Frege established a formal language,that is,concept writing.On the base of the formal language established,he completed the calculus system to pursue truth.Then Frege researched on truth through studying sentence.In pursuing truth,Frege persists in three principles：objectivity,context principle and distinction between concept and object.Frege’s theory of truth has certain significance for the shift of future logic study,of today’s philosophy study and of traditional Chinese thinking in the future.
