Seneca · Some arguments in favour of the simple life
Letters 87.30
Certain men answer this objection as follows: “You are mistaken if you ascribe disadvantages to riches. Riches injure no one; it is a man’s own folly, or his neighbour’s wickedness, that harms him in each case, just as a sword by itself does not slay; it is merely the weapon used by the slayer. Riches themselves do not harm you, just because it is on account of riches that you suffer harm.”
Seneca, Letters to Lucilius 87.30, translated by Richard Mott Gummere
