The question of the unity of virtues derives from Socratic and Aristotle, they believe that all virtues are united in one form due to the moral knowledge or practical wisdom. According to Aristotle's ethics, Jiyuan YU reconstructs the theory of Confucian unity of virtues, and thinks that any real virtue must contain three virtues, i.e., social rites (li, 禮), benevolence (ren, 仁) and appropriateness (yi, 義). I think YU's interpretation of Confucian virtue ethics is too Aristotelian. Confucius indeed believes that all virtues are united, his thoughts can be reconstructed as two levels, the first is benevolence is complete virtue and all virtues are united in it, the second is the unity of benevolence and wise (zhi, 智). As far as the two level of unity of virtues, Confucius is different from that of Aristotle. Comparatively, Confucius' theory of unity of virtues is more plausible.
