O philosophy, life's guide! O searcher-out of virtue and
expeller of vices! What could we and every age of men have been
without thee? Thou hast produced cities; thou hast called men
scattered about into the social enjoyment of life.
[Lat., O vitae philosophia dux! O virtutis indagatrix,
expultrixque vitiorum! Quid non modo nos, sed omnino vita
hominum sine et esse potuisset? Tu urbes peperisti; tu
dissipatos homines in societatum vitae convocasti.]
— Cicero (Marcus Tullius Cicero)
