Locke's Abstract Ideas: Name and Meaning

In Locke's empirical world, the formation and expression of abstract ideas is inevitable, and the process of human experience is always accompanied by the existence of abstract ideas.Locke's concept of an abstract idea has its own position and content in one's thinking; it embodies reality as an abstract idea.It also holds the "name" of the reality in the use of natural language and conjures the semantic world.Establishing the relationship between name and reality is free and arbitrary,so the concept of an abstract idea in one's thinking and in the experience of language is not always the same.Names and reality of experience are not always based on necessary unity.In the sense of an abstract idea,the distinction and unification of a name and reality are only possible and realistic if we return to the world in which the rational subject exists.
