Mencius (c. 372-289 BCE), known in Chinese as Mengzi ("Master Meng") and by the personal name Meng Ke, is the most influential Confucian thinker after Confucius himself, honoured in the tradition as the "Second Sage." Living during the turbulent Warring States period, he travelled among the feudal courts urging rulers to govern through benevolence (ren) and righteousness (yi) rather than force, and he developed the doctrine for which he is best known: that human nature is innately good, endowed with the "four beginnings" of compassion, shame, courtesy and moral judgement, which education and self-cultivation bring to fruition. He also articulated an early theory of just rulership, holding that a sovereign who loses the welfare and trust of the people forfeits the Mandate of Heaven. His conversations and arguments were gathered in the book that bears his name, the Mengzi, which the Neo-Confucian philosopher Zhu Xi later canonised as one of the Four Books, and his optimistic account of human nature became Confucian orthodoxy for much of East Asian history.

Human Nature Is Good: The Four Sprouts
Mencius (Mengzi, 4th century BCE) is, after Confucius himself, the most important figure of the Confucian tradition, and his signature doctrine is that human nature is good (xing shan). Human beings, he argued, are born with the incipient "sprouts" (duan) of the four cardinal virtues, the feeling of compassion, which is the sprout of benevolence (ren); the feeling of shame, the sprout of righteousness (yi); the feeling of deference, the sprout of ritual propriety; and the sense of right and wrong, the sprout of wisdom. His famous thought-experiment makes the case: anyone who suddenly saw a child about to fall into a well would feel a pang of alarm and pity, not from calculation but spontaneously, proof that the moral sprout is native to us. Morality, then, is not imposed from outside but cultivated from within, like tending a plant; a person becomes bad only by starving or damaging what was originally there. This optimistic account of human nature, framed against rivals like Yang Zhu and the Mohists, became central to later Confucian thought.
The Mandate, and the Right to Rebel
Mencius drew from his view of human nature a bold political ethic. Since the moral sense is universal, government exists for the people's welfare, and its legitimacy is conditional on serving them: a ruler who practises "benevolent government" (ren zheng), securing the people's livelihood and moral education, holds the Mandate of Heaven (tianming), while a ruler who oppresses them forfeits it. Mencius pressed this to its startling conclusion, that a tyrant who has lost the Mandate has ceased to be a true king and become a mere "fellow," so that removing him is not regicide but the just deposing of a criminal.
"The people are the most important element," he taught; "the ruler is the least." This gave the Confucian tradition a principled, if carefully bounded, justification for resistance to tyranny. Mencius's stature grew over the centuries until, in the Song dynasty, the Neo-Confucian Zhu Xi placed the Mencius among the Four Books at the heart of the classical curriculum, where it shaped the education of every Chinese official for six hundred years.
