He (?), or harmony, has traditionally been a central concept in Chinese thought, and to this day continues to shape the way in which people in China and East Asia think about ethics and politics. Yet, there is no systematic and comprehensive introduction of harmony as has been variously articulated in different Chinese schools. This edited volume aims to fill this gap. The individual contributions elaborate the conceptions of harmony as these were exemplified in central Chinese schools of thought, including Daoism, Confucianism, Legalism, Mohism, Buddhism, and trace their impact on contemporary Chinese philosophy. The volume explores the various meanings and implications of harmony so as to consider its relevance as a value and virtue in the modern world. It provides an accessible but substantial introductory work for readers interested in learning about pertinent core concepts and theories in Chinese thought, as well as engages specialists in Chinese philosophy by explicating its implications for ethical, political, epistemological, and metaphysical reflection as the basic point of reference.
