概念是客观事物特有属性在人们头脑中的反映。概念一经形成,在一定的具体条件下,有它的确定性。人们说话、写文章都要使用概念,如果我们不能准确地理解概念,便往往容易产生用词不当的弊病。语意的精确,来自概念的明确。列宁说:“要进行论争,就要确切地阐明各个概念。”斯大林也说:“为了避免发生混乱,我们必须预先确定我们所使用的概念。” Concept is the reflection of the peculiar attributes of objective things in people’s minds. Once a concept is formed, it has certainty under certain conditions. When people speak and write articles, they use the concept. If we can not understand the concept accurately, we tend to be prone to misunderstandings. Semantic precision, from the concept of clear. Lenin said: “In order to debate, it is necessary to clarify concepts.” Stalin also said: “In order to avoid confusion, we must determine in advance the concepts we use.”
