Seneca · On the lesson to be drawn from the burning of Lyons
Letters 91.21
Then let not this sort of thing damage death, either, in our estimation; death also is in bad odour. But no one of those who malign death has made trial of it.
Meanwhile it is foolhardy to condemn that of which you are ignorant. This one thing, however, you do know—that death is helpful to many, that it sets many free from tortures, want, ailments, sufferings, and weariness. We are in the power of nothing when once we have death in our own power! Farewell.
Seneca, Letters to Lucilius 91.21, translated by Richard Mott Gummere
