Letters 76.24

If anything except the honourable is good, we shall be hounded by greed for life, and by greed for the things which provide life with its furnishings,—an intolerable state, subject to no limits, unstable. The only good, therefore, is that which is honourable, that which is subject to bounds.

Seneca, Letters to Lucilius 76.24, translated by Richard Mott Gummere
