The Plague of Reason
The idea that the ethical logic of our existence causes us to suffer is enough to dazzle all of humanity, and it is completely unbelievable. How does the fundamental logic of existence cause us to suffer? This is beyond our knowledge. How can life be suffering? It is God's and God's plan, and it is not for us to ask about it, is it? We don't need religious ideas to explain why the human world is plagued with disasters. We only know that it is an objective fact, an existential necessity. We do not associate the suffering of life with the reason for survival, the reason for survival leads to the suffering of life, a connection we have never thought of.

Human strength and dexterity are not as good as other animals, what makes people survive? It is mainly by spiritual wisdom. How does a man survive by wisdom? First of all, wisdom separates man from existence, and existence becomes the object of man's knowledge, choice, and use. By separating man from existence and objectifying it, man is free from the regulation and check of existence itself, and he can live selectively according to his own chosen mode of consciousness and behavior, i.e., he can effectively grasp certain things to gain some initiative.
