Chapter 15, Gentleman and Villain (卫灵公, Wèi Líng Gōng), named after Duke Ling of Wei, presents one of the most important distinctions in Confucian philosophy: the contrast between the superior person (君子, Jūnzǐ, gentleman) and the small person (小人, Xiǎo Rén, villain/petty person). This chapter systematically explores how these two types differ in their values, behavior, and ultimate destiny.
Confucius teaches that the gentleman seeks what is right (义, Yì) while the small person seeks what is profitable (利, Lì). The gentleman is dignified but not proud; the small person is proud but not dignified. The gentleman is at ease without being idle; the small person is idle without being at ease.
The chapter also addresses the question of how to maintain one's moral principles in a corrupt world. Confucius acknowledges that the gentleman may suffer poverty and obscurity, but insists that true worth is independent of external success. He teaches that the superior person is concerned about leaving a name worthy of remembrance, not about material comfort.
