Philosophy You must first know what philosophy is used for. Simply put, philosophy is a subject that studies the nature and connection of things. If we only use philosophical thoughts, we can have such an understanding. History and philosophy don't seem to distinguish, and the time sequence doesn't matter. What happened, we only pay attention to its existence. For example, when you see a beautiful vase, you will admire its beauty. Philosophically, you just see the essence, just like a handful of loess. Do you see it?

This is to study the essence and connection from the perspective of pure philosophy. So it is enough for history to see its existence and understand its rationality. Because in fact, for pure philosophy, history and vase are one thing, and both are one thing. There is no difference.

I'm talking about pure philosophy. I don't analyze history with philosophical theories extended from philosophy. ..
