从《思想》一文看弗雷格的逻辑研究

A Study on Frege's Logic Research from the Perspective of Thought

弗雷格认为,逻辑研究的对象是"真"。因此,他用一系列论文来讨论"真",而每篇的侧重点各有不同。但无论如何,这些文章都是围绕一个共同的研究方式——语句分析,由此可以看出其彼此的关联:《论涵义和意谓》区分了句子的含义和意谓两个层次,并说明句子的意谓是真值。而在《思想》一文中,思想是一种含义,真值是研究对象,从思想到真值正是从含义到意谓的应用。

In Frege＇ s opion, ＂truth＂ is the objective of logic research. So he discussed the ＂truth＂ in a series of articles. And each has different emphasis. However, all these articles have the same subjects a- bout what the study method is - sentence analysis. So we can see their relationship from each others ： the article On sense and reference made a distinction between sense and reference in a sentence, and said that a sentence＇s reference is a truth value. While in the article Thought ,thought is defined as a kind of sense, and truth is the subject of logic research, so the relationship between thought and truth can be looked as an application of the study on sense and reference.
