Confucianism, also known as Ruism or Ru classicism, is a system of thought and behavior originating in ancient China, and is variously described as a tradition, philosophy, religion, theory of government, or way of life. Founded by Confucius in the Hundred Schools of Thought era (c. 500 BCE), Confucianism integrates philosophy, ethics, and social governance, with a core focus on virtue, social harmony, and familial responsibility.
Confucianism emphasizes virtue through self-cultivation and communal effort. Key virtues include ren (仁, "benevolence"), yi (義; "righteousness"), li (禮; "propriety"), zhi (智; "wisdom"), and xin (信; "sincerity"). These values, deeply tied to the notion of tian (天; "Heaven"), present a worldview where human relationships and social order are manifestations of sacred moral principles. While Confucianism does not emphasize an omnipotent deity, it upholds tian as a transcendent moral order.
