Things sacred should not only be touched with the hands, but unviolated in thought.
[Lat., Res sacros non modo manibus attingi, sed ne cogitatione quidem violari fas fuit.]
That man is guilty of impertinence who considers not the circumstances of time, or engrosses the conversation, or makes himself the subject of his discourse, or pays no regard to the company he is in.
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.]
Oh, how great is the power of truth! which of its own power can easily defend itself against all the ingenuity and cunning and wisdom of men, and against the treacherous plots of all the world.
