The poem
Know then thyself, presume not God to scan The proper study of Mankind is Man. Placed 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 and body to prefer; Born but to die, and reas'ning but to err; Whether he thinks to 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.
