Know then thyself, presume not God to scan; The proper study of Mankind is Man. Plac'd on this isthmus of a middle state, A being darkly wise, and rudely great: With too much knowledge for the Sceptic side, With too much weakness for the Stoic's pride, He hangs between; in doubt to act, or rest; In doubt to deem himself a God, or Beast; In doubt his Mind or Body to prefer, Born but to die, and reas'ning but to err; Alike in ignorance, his reason such, Whether he thinks too little, or too much: Chaos of Thought and Passion, all confus'd; Still by himself abus'd, or disabus'd; Created half to rise, and half to fall; Great lord of all things, yet a prey to all; Sole judge of Truth, in endless Error hurl'd: The glory, jest, and riddle of the world!
An Essay on Man, Alexander Pope (1688 - 1744)
