excerpt: superficial observers tend to believe that arbitrary rule is characterized by brutality and poverty. In fact, the cruel meaning is the lack of tacit coordination. The child feels that the teacher is cruel, and the mother and brothers and sisters are not cruel. The soldiers felt that the officers were cruel and the wife was not cruel. The reason is not that the material conditions of the school and the army must be lower than the family, or that the obligations required by the school and the army must be higher than the family in terms of difficulty, but that the rational control of equal treatment is not in accordance with various special historical paths, and the complexity of the interaction rules. A private relationship or organic connection that is beyond reason. The organic community is equally cruel to outsiders, but members of the community unconsciously feel that this is taken for granted.
