Seneca · On asthma and death
Letters 54.7
Accept this assurance from me: I shall never be frightened when the last hour comes; I am already prepared and do not plan a whole day ahead. But do you praise and imitate the man whom it does not irk to die, though he takes pleasure in living. For what virtue is there in going away when you are thrust out? And yet there is virtue even in this: I am indeed thrust out, but it is as if I were going away willingly. For that reason the wise man can never be thrust out, because that would mean removal from a place which he was unwilling to leave; and the wise man does nothing unwillingly. He escapes necessity, because he wills to do what necessity is about to force upon him. Farewell.
Seneca, Letters to Lucilius 54.7, translated by Richard Mott Gummere
