Confucianism, a chain of thought that literates the basic characteristic of human existence being in sociological relationship among people. Pre-T’sin period Confucianism defines a person relating to others as entities and such co-relation among people, these relationship entities makes the basic structure to form a society. The biggest theological difference of Confucianism is that it focuses on sociological aspect of human beings rather than biological characteristic. Confucius, Mencius, Xun-Zi, all the philosophers of Confucianism claim the basic characteristic of human existence upon sociological relationship between man and others. Therefore, notion of ‘social relationship entity’ can be the core in defining the characteristic of human existence in thoughts of Confucianism. In other words, the core thought of Confucianism can be said as the existence of moral aspect of a human being, extracted through existence of sociological relationship. Such aspect was to suggest an ideal state of a noble man and to understand their social relationship and to solve problems arising within that social relationship. Pre-T’sin period Confucianism focuses on basic social relationship between people as well as primary group relationships such as family, focusing on social order and harmony upon human life. The main drive of social relationship among people depends on individual roles and part take in social relations, at the same time reclaiming courteous vicissitudes of life, help to do good to others and necessities of ancient society formation. These are the main core interests of social relations for Pre-T’sin period Confucianism. Materialism and individualism brought about the deficiencies of selfness and social commune upon this modern world. I think that the social philosophical approach method of the pre-T’sin period Confucianism will not only shed a new light on the human nature in modern society but also play a important role in the recovery of selfness and social commune consciousness, basing on the entity of human beings through social relations.
