“Learned we may be with another man's learning: we can only be wise with wisdom of our own.”

“We do not want our world to perish. But in our quest for knowledge, century by century, we have placed all our trust in a cold, impartial intellect which only brings us nearer to destruction. We have heeded no wisdom offering guidance. Only by learning to love one another can our world be saved. Only love can conquer all.”

“A wise man can learn more from a foolish question than a fool can learn from a wise answer.”

“We learn, when we learn, only from experience, and then we only learn from our mistakes. Our successes only serve to reinforce our superstitions.”

“To make no mistakes is not in the power of man; but from their errors and mistakes the wise and good learn wisdom for the future.”

“By trying we can easily learn to endure adversity. Another man's, I mean.”

“Many who have not learned wisdom live wisely, and many who do the basest deeds can make most learned speeches.”

“Epops: A man may learn wisdom even from a foe.”

“Search not to find how other men offend,
But by that glass thy own offences mend;
Still seek to learn, yet care not much from whom,
(So it be learning) or from whence it come.
Of thy own actions, others' judgments learn;
Often by small, great matters we discern:
Youth what man's age is like to be doth show;
We may our ends by our beginnings know.”

“Learning to be wise has a deeper purpose than just learning to be smart. To become wise, we must learn to understand and master things we do not know. Learn from the mistakes we make ourselves. Learn from the mistakes other people make, and find out how other people achieved success.”
