It can be seen from ancient Greek philosophy that the science of naming was originally formed by human beings digging out ideas from physical phenomena, forming concepts, and making this distinction and logically defining the denotation and connotation.
It can be seen from modern Western philosophy (from Leibniz to Hume, Kant, and Hegel), especially when studying Marx, we know that matter is an entity and matter has a state. It is necessary to separate matter from the pattern of matter. The pattern of a substance is the "name" of the substance. When naming a substance, it is the process of formation of the substance and the pattern.
For example, we say that "Zhang San" exists and "Li Si" exists, but does "person" exist? "People" are just the uniqueness of individuals like Zhang San and Li Si, and are the concrete manifestations of these individuals. This "person" does not exist, but is just the concept and thought content of (name). It is our spatial understanding of this concept. We It can be said that it exists because we made it into an entity and gave it a name. There is no such entity as "person".
Philosophy discusses what the world is. The world in most of our minds now is the world described to us by scientists. We think of it as something objective and independent of our existence. We think of it as the only thing. However it is just a description. Description involves language.
It can be seen from Saussure's linguistics that names and language are a symbolic system based on relationships, and horizontal combination and vertical aggregation relationships are the most common and core relationships in this system. As a symbolic system, the various elements of names in a language are related to each other rather than existing in isolation.
