Mencius, Confucianism's Second Sage: Why He Believed People Are Born Good and Bad Rulers Can Be Removed

Mencius (c. 371 – c. 289 BC), born Meng Ke, was a Chinese Confucian philosopher traditionally honoured as the "Second Sage", second only to Confucius himself; he taught that human nature is fundamentally good and humane, that rulers must govern with benevolence, and that a ruler who abandons righteousness loses the Mandate of Heaven and may rightly be overthrown. The book that records his conversations, the Mencius, became one of the core texts of Confucian education for more than a thousand years.

A wandering philosopher from Zou

Mencius was born in the small state of Zou, in what is now Zoucheng in Shandong province, not far from Confucius's home town. He is said to have studied under a pupil of Confucius's grandson, Zisi, and like Confucius he became an itinerant teacher, travelling from state to state during the violent Warring States period, trying to persuade kings to rule with humanity. Most of them listened politely and ignored him; they wanted advice on winning wars, not on being kind.

The mother who moved three times

Mencius's father died when he was very young, and he was raised by his mother, who is still held up in Chinese culture as a model parent. According to a famous story, she moved house three times to find the right environment for her son: first they lived near a cemetery, and the boy played at funerals; then near a market, and he played at buying and selling; finally near a school, where he began to imitate the students' manners and learning, and there she stayed. Another story says that when the young Mencius neglected his studies, she cut the cloth she was weaving to show him that an unfinished education is as useless as a cut piece of cloth. The four-character idiom 孟母三迁, "Mencius's mother moved three times", is still used today to describe parents who care deeply about their child's surroundings.

Human nature is good

Mencius's central idea is that human nature is righteous and humane. He argued that every person is born with "sprouts" of goodness. His most famous example: anyone who suddenly sees a small child about to fall into a well will feel alarm and compassion, not because they want a reward or fear blame, but because that feeling is natural. These sprouts, he said, must be cultivated through education and good surroundings, just as a plant must be watered. This view was later challenged by the philosopher Xunzi, who argued that human nature is bad and must be corrected by rules.

The people come first

Mencius's political ideas were bold for his time. He believed that a state with righteous and humane policies will flourish naturally, because citizens who live freely under good rulers will willingly support them. He is famous for saying that the people are the most important element of a state, the altars of the land and grain come next, and the ruler matters least. He went further than Confucius in arguing that a cruel tyrant has lost the Mandate of Heaven and can no longer be called a true king, so removing him is not rebellion but justice. Some later emperors found this so uncomfortable that they tried to cut such passages from the book.

Legacy

Mencius was buried near Zoucheng, where a large cemetery and temple still honour him. Centuries later, Neo-Confucian scholars placed the Mencius among the Four Books that every candidate for the imperial examinations had to master, so his ideas shaped education and government in China, Korea, Japan and Vietnam for generations. His belief in the natural goodness of people still offers a hopeful view of human beings.
