- Confucius (plato.standford.edu)
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.
