Cicero: I would fain have some tincture of all the virtues, there is no quality I would sooner have, and be thought to have, than gratitude. For gratitude not merely stands alone at the head of all the virtues, but is even mother of all the rest. What is filial affection, if not a benevolent gratitude to one’s parents? What is patriotism, what is service to one's country in war and peace, if it is not a recollection of benefits received from that country? What is piety and religion, save a due reverence and remembrance in paying to the immortal gods the thanks that we owe? Take friendship away, and what joy can life continue to hold? More, how can friendship exist at all between those who are devoid of gratitude?
