Human nature is good. Like water flows downhill, the heart flows toward compassion. Nurture it, and virtue grows.
Mencius was Confucius' most important successor. He argued that human nature is good at its root: anyone who sees a child about to fall into a well will feel alarm and compassion, not because of any reward but because that is what it means to be human. Evil comes not from our nature but from neglect and bad conditions, the way fertile soil produces weeds when unattended. He traveled the Warring States like Confucius before him, advising rulers that a king who loses the mandate of heaven through cruelty can rightfully be overthrown.
“If you let people follow their feelings, they will be able to do good. That is what I mean by saying human nature is good.”
Born in the small state of Zou, near Confucius's homeland. His mother famously moved houses three times to find the right neighborhood for his education. He grew up steeped in the Confucian tradition.
Like Confucius before him, Mencius spent years traveling between courts, urging kings to govern through benevolence rather than force. Like Confucius, he was mostly ignored. He kept arguing anyway.
Asked his listeners to imagine seeing a child about to fall into a well. Everyone, he said, would feel alarm and compassion. Not for reward, not for reputation. That instinct proves human nature is good at its root.
