Seneca · On the fickleness of fortune
Letters 98.18
Up to now we have dealt with arguments—whether any man can resist pain, or whether the approach of death can cast down even great souls. Why discuss it further? Here is an immediate fact for us to tackle—death does not make our friend braver to face pain, nor pain to face death. Rather does he trust himself in the face of both; he does not suffer with resignation because he hopes for death, nor does he die gladly because he is tired of suffering. Pain he endures, death he awaits. Farewell.
Seneca, Letters to Lucilius 98.18, translated by Richard Mott Gummere
