A library, to modify the famous metaphor of Socrates, should be the delivery room for the birth of ideas — a place where history comes to life.
Socrates — quotes and aphorisms
Think not those faithful who praise all thy words and actions; but those who kindly reprove thy faults.
Remember that there is nothing stable in human affairs; therefore avoid undue elation in prosperity, or undue depression in adversity.
If a man is proud of his wealth, he should not be praised until it is known how he employs it.
