isthmus Quotes

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 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.

—Pope, Alexander
