Knowledge profits those who know how to use it. Ignorance hurts those who use it. Folly ruins those who practice it.

Only fools befriend ignorance, and they pay the price. Only the wise befriend wisdom, and they reap the rewards. We are all ignorant of something, but some are ignorant of everything.

Fall from ignorance, and you will rise to reason.

Ignorance is the greatest slave master in the universe.

Not all slaves are poor, and not all free men are rich.

Pride can destroy a man quicker than ignorance.
