Lust is an enemy to the purse, a foe to the person, a canker to the mind, a corrosive to the conscience, a weakness of the wit, a besotter of the senses, and finally, a mortal bane to all the body.
Pliny the ElderAs in our lives so also in our studies, it is most becoming and most wise, so to temper gravity with cheerfulness, that the former may not imbue our minds with melancholy, nor the latter degenerate into licentiousness.
Pliny the ElderIt is this earth that, like a kind mother, receives us at our birth, and sustains us when born; it is this alone, of all the elements around us, that is never found an enemy of man.
