The Five Human Relationships
Confucian teachings are based on five human relationships that are founded on moral principles. The five human relationships include those between husband/wife, parent/child, siblings, friends, and political leaders and the public. Husband/wife represents the smallest and the most intimate circle of human relationships. Outside the small circle is the extended family, which includes the relationships between father and son and those among the siblings. Outside the family there is society which includes additional relationships between the individual and his leader and circles of friends. We now often talk about the need to unite people. In ancient times, the Chinese had no use for the word "unite," for the five human relationships define the union of all people. Everyone on this earth is our brother. Each is responsible for the other; parents being compassionate, sons and daughters being filial to their parents, siblings and friends being respectful to each other. In this way, the country and its people are already a perfect union. The relationships between people also define responsibilities from one to the other. Everyone has his own duty and responsibility to fulfill.
