Jen and li are key concepts for Confucianism. Humanity means co-humanity. The order of the universe is completed only with the appearance of real moral order in human affairs. This nature must be cultivated or consciously formed through education or culture. With learning and study and practice of what is good, man's original compassion can be nurtured and become fully mature moral character or jen.
Education is the nurturing and refinement of co-humanity.
In general, Chinese philosophers have presupposed that human nature is originally good or innocent. Compare this view to that of medieval and modern Western philosophy. Like nature as a whole, human nature, free of passion and movement, is in equilibrium, perfect balance. In the superior person, the harmony of the self extends outward and harmonizes the world it inhabits. The superior person's life is, as it were, a work of art, a ritual, a ceremony, wherein every movement has its place, is exactly as it should be, a perfect harmony.
