The subject of this article is to compare and analyze the meanings of the sentiments in Spinoza’s Ethica and sheng yi sim’s The change of humans. The problem of emotion in modern society is an important social problem. In this atmosphere, Spinoza is attracting attention. Modern society emphasizes desire and emotion rather than reason. Emotions should now be viewed from a positive perspective, not a negative view. The study of emotion in the 20th century was largely dominated by cultural theory. Emotions, like languages, are culturally transmitted and learned. According to modern language philosophical insights, language constitutes experience, not reflection. If this language philosophical insight is correct, then the role of language is crucial in understanding and experiencing emotions. Language has a temporal and spatial context. Language has historicity and sociality. In order to understand the emotional aspects of what is happening in our society, we must understand the historical and social context of the emotional expressions in our language. The emotional expression in our language has our own East Asian history. In this regard, it is necessary to study our language, which is different from Western studies, in historical context. In order to understand our emotions in the historical and social context of a language other than the West, we are paying attention to sheng yi sim’s The change of human, the literature of the period of the 17th-18th century Joseon Dynasty, similar to that of Spinoza.
