Abstract
From the perspective of perceptual ontology, Laozi criticizes the unnatural state in which the body is concealed in the perceptual social power and ethical relations, and advocates the perceptual liberation of the body. According to different subjects of the body, the covered body should be divided into people’s body and monarchs’ body. The body of the people is concealed in the rites and music, and could be liberated by resuming production; the body of the monarchs is covered in the excessive exercise of power, and could be liberated in the restraint of power. The body is not only in the ethical relationship of the different order pattern, but also in the power relationship of the same structure of family and country. The power, body and ethics form the internal structure of trinity. The perceptual existence of the body is the basis of power and ethics, and the perceptual liberation of the body is the purpose of power and ethics.
