“’ Death is nothing to us’ was likely said by Sophron, but Epicurus proved it; and it is not the claiming of a thing but the proving that is a wonder. And, for that matter, Epicurus did not say that ‘death is nothing to us’ because there is no difference in living or not living—-life is preferable by far because what is good belongs to the world of perception. But where there is no perception, there is neither good nor evil. The fact that corpses do not feel is something the poet knows along with the rest of creation.”
τό τε τὸν θάνατον [μὲν] μηδὲν εἶναι πρὸς ἡμᾶς εἴρηται μὲν ἴσως τῷ Σώφρονι, ἀποδέδεικται δὲ ᾿Επικούρῳ, καὶ ἔστιν οὐ τὸ εἰπεῖν ἀλλὰ τὸ ἀποδεῖξαι θαυμαστόν. εἶτα οὐδὲ κατὰ τοῦτο ἔφησεν ὁ ᾿Επίκουρος τὸν θάνατον μηδὲν εἶναι πρὸς ἡμᾶς, καθὸ ἀδιάφορόν ἐστιν ἢ ζῆν ἢ μή• πολλῷ γὰρ αἱρετώτερον τὸ ζῆν διὰ τὸ αἰσθανομένων εἶναι τὸ ἀγαθόν• ἀλλ’ ἐν ἀναισθησίᾳ οὔτε κακόν τι εἶναι οὔτε ἀγαθόν. τὸ μὲν γὰρ ἀναισθητεῖν τὰ νεκρὰ τῶν σωμάτων οὐχ ὁ ποιητὴς μόνος οἶδεν ἀλλὰ καὶ ὁ σύμπας βίος.
Sophron? Probably less of a household name than Sextus Empiricus.
