Discretion of speech is more than eloquence, and to speak agreeably to him with whom we deal is more than to speak in good words, or in good order.
Francis Bacon (1561-1626) British statesman and philosopher.
Be wiser than other people, if you can; but do not tell them so.
Lord Chesterfield (1694-1773) British statesman.
For he that fights and runs away, may live to fight another day, but he, who is in battle slain, can never rise and fight again.
Oliver Goldsmith (1728-1774) Irish writer, poet, and physician.
Nothing is more dangerous than a friend without discretion; even a prudent enemy is preferable.
Jean de La Fontaine (1621-1695) French poet.
Better a living dog than a dead lion.
