Letters 66.40
“There is no doubt,” says the objector, “that peace affords more happiness when it has not been assailed than when it has been recovered at the cost of great slaughter.” “There is no doubt also,” he continues, “that health which has not been impaired affords more happiness than health which has been restored to soundness by means of force, as it were, and by endurance of suffering, after serious illnesses that threaten life itself. And similarly there will be no doubt that joy is a greater good than a soul’s struggle to endure to the bitter end the torments of wounds or burning at the stake.”
