"Men never do evil so completely and cheerfully as when they do it from religious conviction"
About this Quote
The intent isn’t a cheap dunk on religion so much as a diagnosis of moral psychology. Pascal, a devout Christian and a brilliant skeptic of human self-knowledge, is pointing to the way faith can become an alibi for the ego. Religious certainty offers an escape hatch from doubt, and doubt is often the last brake on cruelty. Once an act is framed as obedience to God, the actor stops having to negotiate with empathy, ambiguity, or competing claims of humanity. The person doing harm can even experience themselves as virtuous in the moment they are least so.
Context matters: 17th-century France was thick with theological warfare, factionalism, and the politics of salvation. Pascal lived amid Jansenist controversies and a Church-state ecosystem where doctrine had teeth. His target is the dangerous fusion of moral absolutism and institutional power: when a community elevates belief into unquestionable authority, violence becomes not a regrettable exception but a proof of fidelity.
