Mencius

Mencius (Mengzi) was a Chinese philosopher regarded as the most important Confucian thinker after Confucius himself. He developed Confucius's ethics into a systematic philosophy grounded in his conviction that human nature is fundamentally good — that benevolence, righteousness, ritual propriety, and wisdom are innate in all people, though they may be obscured by circumstance. His political philosophy held that rulers govern by moral example and that the people have the right — even the duty — to overthrow a tyrant.
