The brain is the place of thought. As people started eating cooked meat, they could use their energy to digest raw meat for brain development, and they no longer needed thick, strong jawbones and teeth. The tongue moved freely in the broader space, accelerating language use.
Language = Thinking,
The conclusion is that using fire has increased the quantity and quality of human thoughts.
The legal system, which began in China in the late Neolithic Age, inherits the status of monogamy and the eldest son and is an essential foundation for the structure of consciousness that penetrates the entire Chinese history. It also influenced a culture that emphasized blood ties and age in Korea. The legal system shows a change in thought and is an attempt by a human being immersed in blood ties to confirm the basis of his existence and the legitimacy of his actions. The concept of ‘virtue’ emerged when the Zhou Dynasty destroyed the silver state that received the heavenly realization and caused a legitimacy problem. If there is virtue, the thousand will come; if there is no virtue, the thousand can leave. It was called ‘Yes’ to follow the procedure designed as ‘virtue,’ a mind purified through rituals.
We have come to the level of philosophy that deals with the problem of the relationship between nature and man and the world and man. If the Eun Dynasty prioritized God and ghosts, and there was no framework for the relationship between humans, the Zhou Dynasty separated gods and ghosts around virtue, believing in the power of human existence, and worked with dignity itself.

Zhu Xi, a philosopher of the Song Dynasty, defined virtue that was not real as ‘what’ and made it a noun. In his university book, he naturalized virtue, saying, ‘Since heaven has given people, the nature of humanity, righteousness, art, and wisdom has already been given to everyone.’ The meaning of virtue was the purest refined state of mind prepared enough to know the will of heaven. Confucius also said in his thesis, ‘Because there is no virtue in moving the rumors I heard on the street here and there.’ It means that you are trapped in prejudice because you have lost your inner strength.
