“Remorse is not among the eternal verities. The Greeks were right to dethrone her. Her action is too capricious, as though the Erinyes selected for punishment only certain men and certain sins. And of all means to regeneration, Remorse is surely the most wasteful. It cuts away healthy tissues with the poisoned. It is a knife that probes far deeper than the evil.”
— E. M. Forster, Howards End (1910), chapter 41.
“Le remords s'endort durant un destin prospère et s'aigrit dans l'adversité.”
— Remorse goes to sleep during a prosperous period and wakes up in adversity.
