“I often had no scruples about deceiving nitwits and scoundrels and fools when I found it necessary. ...We avenge intelligence when we deceive a fool, and... deceiving a fool is an exploit worthy of an intelligent man.

“Beauty without wit offers nothing but the enjoyment of its material charms, whilst witty ugliness captivates by the charms of the mind, and at last fulfils all the desires of the man it has captivated.”

“There is no such thing as a perfectly happy or perfectly unhappy man in the world. One has more happiness in his life and another more unhappiness, and the same circumstance may produce widely different effects on individuals of different temperaments.”
