《孟子》文本中“心”概念的使用较为频繁。我们可以通过分类的方法对其“心”概念进行分析和注解。在《孟子》文本表达的语境中，其“心”概念的涵义主要指心理意识活动。后世学者在注解《孟子》“心”概念的过程中，出现了将其形而上学化的倾向。这是注解者根据自己的哲学立场作出的过度解释。获取对“心”概念的合理解释途径，需要正确分析心物之间的关系。

The concept of mind-heart (xin) is applied quite frequently in Mencius. This paper analyses the meaning of this concept by the means of classification. In the original context of Mencius, it mainly means psychological activities. However, a metaphysical tendency appeared in the interpretation of this concept after the Han Dynasty, which can be regarded as a result of the excessive interpretation of annotators according to their own philosophical positions. A correct understanding of the relation between mind-heart and things is essential to a reasonable interpretation of the concept of mind-heart.
