An ignorant person is quick to pick up a sword; a wise person is quick to pick up a book.

Pride can destroy a man quicker than ignorance.

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.

Tell a man, he might understand; show a man, he will understand.

Knowledge helps its enemies, but ignorance harms its friends.

Knowledge sets you free the moment it arrests you.
