论弗雷格的概念

Frege’s Concept

弗雷格将数学中的函数概念扩展到自然语言中并且称之为概念,从而在概念的基础上开启了他的逻辑主义事业。在数学中,函数有着严格的定义,但是,在自然语言中如何来理解弗雷格的函数呢?通过将数学中的函数与自然语言的概念进行比较,分析了弗雷格概念的逻辑结构以及概念的前域和后域,并概述了弗雷格概念的哲学意义。

Frege extends the idea of function-argument analysis from mathematics to logic and calls it concept,and starts his project of logicism.In mathematics,a function is rigorously and precisely defined,while how will it be reshaped after being extended to natural language？ This is the question that this paper centers on.By comparing the notions of function in mathematics and concept in natural language,the logical structure of concept in Fregean sense is given and the domain and range of concept are analyzed.Finally,the philosophical significance of Frege’s concept is summed up.
