No man can be brave who thinks pain the greatest evil; nor temperate, who considers pleasure the highest god. [Lat., Fortis vero, dolorem summum malum judicans; aut temperans, voluptatem summum bonum statuens, esse certe nullo modo potest.]
"De Officiis". Treatise by Marcus Tullius Cicero, I. 2, 44 B.C..
