“Just Cause: [Learn] not to contradict your father in anything; nor by calling him Iapetus, to reproach him with the ills of age, by which you were reared in your infancy.”

Athenian playwright of Old Comedy -448–-386 BCRelated quotes

                        “If you have an enemy, then learn and know your enemy, don't just be mad at him or her”

Context: When an old and distinguished person speaks to you, listen to him carefully and with respect — but do not believe him. Never put your trust into anything but your own intellect. Your elder, no matter whether he has gray hair or has lost his hair, no matter whether he is a Nobel laureate — may be wrong. The world progresses, year by year, century by century, as the members of the younger generation find out what was wrong among the things that their elders said. So you must always be skeptical — always think for yourself.
