The proper study of mankind is man.
This line opens the second part, or epistle, of Pope's An Essay on Man (1733–34). The full couplet reads: ‘Know then thyself, presume not God to scan; / The proper study of Mankind is Man.’ Pope's advice: rather than prying into God's plans, which lie beyond us, study human nature. ‘Know thyself’ echoes the words inscribed at Apollo's temple at Delphi. Alexander Pope (1688–1744) also gave English ‘to err is human, to forgive divine’ and ‘a little learning is a dangerous thing’.
