关于词项和概念的辨析

The Argumentation about Term and Concept

在逻辑学中,词项作为符号是进行逻辑分析和推演的基本单位,概念是对词项的意义的解释,外延是词项在当下概念所指向的对象的集合下的元素。词项从语法的角度强调它作为命题的一个成分,概念从语义的角度强调它的涵义,二者各有自己的适用范围。简单地用词项取代概念或是用概念取代词项都是不合适的,我们要做的是细心地区分出它们的不同涵义和适用范围,从而正确地理解和使用它们。

In logic, term is a basic unit which carry through logical analyse and proposition derivation. Concept is an explanation of term.Extention is every element in the set of which an object the concept refers to.It is improper to replace term by concept.Similarly,it is wrong to replace concept by term.We should differentiate between their meanings and application range.
