In the Middle Ages a misericorde was a weapon used to put a wounded knight out of his misery. As a theological term, it refers to forgiveness and compassion. In French it has been used as an invocation, notably in Samuel Beckett’s Waiting for Godot: “Christ have mercy on us!” That there may be no one listening (or arriving) remains a central anguish, felt in the depression, addiction and other disorders, that are normal responses to increasingly abnormal culture.
