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;
Chaos of thought and passion, all confused;
Still by himself abused or disabused;
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!
Go, wondrous creature! mount where science guides,
Go, measure earth, weigh air, and state the tides;
Instruct the planets in what orbs to run,
Correct old time, and regulate the sun;
Go, soar with Plato to th’ empyreal sphere,
To the first good, first perfect, and first fair;
Or tread the mazy round his followers trod,
And quitting sense call imitating God;
As Eastern priests in giddy circles run,
And turn their heads to imitate the sun.
Go, teach Eternal Wisdom how to rule—
Then drop into thyself, and be a fool!
