Seneca · On the proper time to slip the cable
Letters 70.9
Socrates might have ended his life by fasting; he might have died by starvation rather than by poison. But instead of this he spent thirty days in prison awaiting death, not with the idea “everything may happen,” or “so long an interval has room for many a hope” but in order that he might show himself submissive to the laws and make the last moments of Socrates an edification to his friends. What would have been more foolish than to scorn death, and yet fear poison?
