“In truth, O judges, while I wish to be adorned with every virtue, yet there is nothing which I can esteem more highly than the being and appearing grateful. For this one virtue is not only the greatest, but is also the parent of all the other virtues.”

Source: Cicero, Marcus Tillius. “Pro Plancio.” Rome, 54 BC.
