Of all the causes which conspire to blind
Man’s erring judgment, and misguide the mind,
What the weak head with strongest bias rules,
Is pride, the never-failing vice of fools.
Whatever Nature has in worth denied,
She gives in large recruits of needful pride;
For as in bodies, thus in souls, we find
What wants in blood and spirits, swell’d with wind;
Pride, where wit fails, steps in to our defence,
And fills up all the mighty void of sense!
If once right reason drives that cloud away,
Truth breaks upon us with resistless day;
Trust not yourself; but your defects to know,
Make use of ev’ry friend—and ev’ry foe.
A little learning is a dang’rous thing;
Drink deep, or taste not the Pierian spring:
There shallow draughts intoxicate the brain,
And drinking largely sobers us again.
Alexander Pope (1688-1744)
