To be angry is to revenge the faults of others on ourselves. - Alexander Pope

Nature to all things fixed the limits fit
And wisely curbed proud man's pretending wit.
As on the land while here the ocean gains.
In other parts it leaves wide sandy plains
Thus in the soul while memory prevails,
The solid power of understanding fails
Where beams of warm imagination play,
The memory's soft figures melt away
One science only will one genius fit,
So vast is art, so narrow human wit
Not only bounded to peculiar arts,
But oft in those confined to single parts
Like kings, we lose the conquests gained before,
By vain ambition still to make them more
Each might his several province well command,
Would all but stoop to what they understand.

The flying Rumours gather'd as they roll'd, Scarce any Tale was sooner heard than told; And all who told it, added something new, And all who heard it, made Enlargements too, In ev'ry Ear it spread, on ev'ry Tongue it grew.

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!
Go, wond'rous 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 follow'rs 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!
