Abstract
Harmony is one of the most important philosophical categories in Chinese Taoism and the practice of Tao in the life of Lao Tzu. It emphasizes the unity of Heaven and Earth, humans, all creatures, society, physical and mental substance. By the demonstration and exposition of many Taoist scholars, Harmony has been greatly extended to the social field, and has been very useful in the development of effective programs to manage conflicts among persons, organizations and states. According to Lao Tzu, Harmony could be achieved by returning back into the power of an infant, since an infant is capable to be peaceful, harmonious, soft and natural. Thus, an infant possesses and manifests the greatest morality.
