Abstract: Mencius’ ideal of moral quality is enriched with "kind" and esthetic moral quality. It is the embodiment of benvolence, justice, courtesy and wit in personality, the concentration of noble spirit, and the harmonious unification of kind and esthetics. Mencius’ personality is the true portraiture of his ideal of moral quality. Mencius’ ideal of moral quality and personality has a permanent fascination. It profoundly influenced the development of the Chinese national nature in the past, and can be used as reference at the present age.
