Seneca · On facing the world with confidence
Letters 105.5
Contempt remains to be discussed. He who has made this quality an adjunct of his own personality, who is despised because he wishes to be despised and not because he must be despised, has the measure of contempt under his control. Any inconveniences in this respect can be dispelled by honourable occupations and by friendships with men who have influence with an influential person; with these men it will profit you to engage but not to entangle yourself, lest the cure may cost you more than the risk.
Seneca, Letters to Lucilius 105.5, translated by Richard Mott Gummere
