Many people think philosophy creates a pile of abstract, obscure, hard-to-understand words, and that it is basically meaningless. But I actually think philosophy is slowly making the abstract concepts that already exist more precise. For example, “country” is actually a very abstract concept, but now we all know what a country refers to. But in ancient society, what exactly was a country? They actually did not have a very concrete concept of it, until society developed and common human understanding gradually made the concept clearer. A lot of things around us already contain these abstract logics of philosophy. But before we come into contact with philosophy, we are like blind people. We can only vaguely sense that those things exist, but we do not know what they really mean.
