The Riddle of the World

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;

Alike in ignorance, his reason such,
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.

Alexander Pope
