 At different times in Chinese history, Confucius (trad. 551–479 BCE) has been portrayed as a teacher, advisor, editor, philosopher, reformer, and prophet. The name Confucius, a Latinized combination of the surname Kong 孔 with an honorific suffix “Master” (fuzi 夫子), has also come to be used as a global metonym for different aspects of traditional East Asian society. This association of Confucius with many of the foundational concepts and cultural practices in East Asia, and his casting as a progenitor of “Eastern” thought in Early Modern Europe, make him arguably the most significant thinker in East Asian history. Yet while early sources preserve biographical details about Master Kong, dialogues and stories about him in early texts like the Analects (Lunyu 論語) reflect a diversity of representations and concerns, strands of which were later differentially selected and woven together by interpreters intent on appropriating or condemning particular associated views and traditions. This means that the philosophy of Confucius is historically underdetermined, and it is possible to trace multiple sets of coherent doctrines back to the early period, each grounded in different sets of classical sources and schools of interpretation linked to his name. After introducing key texts and interpreters, then, this entry explores three principal interconnected areas of concern: a psychology of ritual that describes how ideal social forms regulate individuals, an ethics rooted in the cultivation of a set of personal virtues, and a theory of society and politics based on normative views of the family and the state.
