Letters 70.8

There are times, nevertheless, when a man, even though certain death impends and he knows that torture is in store for him, will refrain from lending a hand to his own punishment, to himself, however, he would lend a hand. It is folly to die through fear of dying. The executioner is upon you; wait for him. Why anticipate him? Why assume the management of a cruel task that belongs to another? Do you grudge your executioner his privilege, or do you merely relieve him of his task?

Seneca, Letters to Lucilius 70.8, translated by Richard Mott Gummere
