Mencius (most accepted dates: 372–289 BCE; other possible dates: 385–BC/302 BCE), also known by his birth name Meng Ke or Ko, was born in the State of Zou (鄒國), now forming the territory of the county-level city of Zoucheng (邹城市), Shandong province, only thirty kilometres (eighteen miles) south of Qufu, Confucius' birthplace. He was an itinerant Chinese philosopher and sage, and one of the principal interpreters of Confucianism. Like Confucius, according to legend, he travelled China for forty years to offer advice to rulers for reform. He served as an official during the Warring States period (403–221 BCE) in the State of Qi (齊 qì) from 319 to 312 BCE. He expressed his filial devotion when he took an absence of three years from his official duties for Qi to mourn his mother's death. Disappointed at his failure to effect changes in his contemporary world, he retired from public life.
A follower of Confucianism, Mencius argued for the infinite goodness of the individual, believing that it was society's influence – its lack of a positive cultivating influence – which caused bad character. He even argued that it was acceptable for people to overthrow or even kill a ruler who ignored the people's needs and ruled harshly. Mencius argued that human beings are born with an innate moral sense which society has corrupted, and that the goal of moral cultivation is to return to one's innate morality.
