Letter 42 — On Values (§10)

““Less influence.” Yes, and less envy. Look about you and note the things that drive us mad, which we lose with a flood of tears; you will perceive that it is not the loss that troubles us with reference to these things, but a notion of loss. No one feels that they have been lost, but his mind tells him that it has been so. He that owns himself has lost nothing. But how few men are blessed with ownership of self! Farewell. ↑ Seneca doubtless has in mind the famous passage of Simonides, ἄνδρ᾽ ἀγαθὸν μὲν ἀληθῶς γενέσθαι χαλεπόν, discussed by Plato, Protagoras, 339 A.”
