Overview

The most important Confucian after Confucius himself, revered as the 'Second Sage'. Mencius developed Confucian ethics with his famous doctrine that human nature is innately good: everyone possesses 'sprouts' of virtue — compassion, shame, courtesy, and a sense of right and wrong — that education and cultivation can grow. In politics he taught benevolent government (ren zheng) for the people's welfare, and boldly asserted that a ruler who fails the people forfeits the 'Mandate of Heaven' and may rightfully be deposed.

What they supported — and why

Human nature is good

SupportedAll humans are born with innate 'sprouts' of virtue — feelings of compassion, shame, courtesy, and right and wrong.

WhyThe spontaneous alarm anyone feels on seeing a child about to fall into a well shows moral feeling is native to us, needing cultivation, not implantation.

Cultivate the sprouts

SupportedMoral development is the growing and extending of our innate good tendencies.

WhyVirtue is nurtured from within, like tending plants, so education draws out what is already there rather than imposing it.

Benevolent government and the Mandate of Heaven

SupportedRulers must govern for the people's welfare; a tyrant who fails them loses Heaven's mandate and may be overthrown.

WhyHeaven sees as the people see; legitimacy rests on caring for the people, so misrule dissolves the right to rule.

Causes championed

  • The innate goodness of humanity
  • Moral self-cultivation
  • Government for the people's welfare

Issues wrestled with

  • Is human nature good, bad, or neutral?
  • How does virtue develop?
  • When is a ruler legitimate?

Hurdles faced

  • An era of ruthless warring states indifferent to benevolence
  • Debating rivals (Mohists, egoists) on human nature
