Mencius
“Are humans naturally good?”
Mencius (Mengzi) was Confucius's most influential follower, living about a century later. He argued that human nature is naturally GOOD — every person is born with what he called the ‘Four Sprouts’: tiny seeds of compassion, shame, courtesy, and a sense of right and wrong. Bad people aren't born evil; their sprouts were never watered. He also taught that a ruler's job is to serve the people — and that a tyrant forfeits the right to rule.
“The great man is he who does not lose his child's heart.”
The big idea
Mencius said human nature is fundamentally good. Every person is born with four ‘sprouts’ — instincts toward compassion, shame, courtesy, and right-and-wrong — that grow into the great virtues if nurtured. His proof: nobody, he said, sees a child about to fall down a well without feeling a sudden pang of alarm and concern. That feeling, before any thought, shows our nature.
What they changed
His view that the people's welfare comes BEFORE the ruler's power became the bedrock of Chinese political ethics. The famous ‘Mandate of Heaven’ — the idea that a tyrant loses heaven's blessing and may rightly be overthrown — was given its sharpest form by Mencius. East-Asian education and government echoed his ideas for two millennia.
The controversy
His optimism was challenged in his own lifetime by Xunzi, who argued the opposite: humans are born selfish and must be civilised by rules. Their debate is still the heart of every nature-vs-nurture argument: are kids basically good, or do we make them good?
