Both “a kind man loves people” and “a wise man knows people”, which embody the Confucian thought connotation, i.e. “the unity of kindness and wisdom”, show the unity of humanism principles and rational principles, and the unity of the true, the good and the beautiful. Confucianism regards “kindness and wisdom” as the main features of ideal personality. Therefore, “the unity of kindness and wisdom” has become the inevitable requirement for people to acquire their ideal personality. Its philosophical implications are rich in modern values, which needs to be researched and will provide profound enlightenments for building a harmonious society and promoting peoples all-round development today.
