"The jealous are possessed by a mad devil and a dull spirit at the same time"
About this Quote
That double description is the quote's engine. It captures the way jealousy can feel like heightened awareness ("I see what's really going on") while actually making a person stupidly repetitive, trapped in the same loops of suspicion. "Mad" and "dull" also imply a theological anthropology: the jealous are not uniquely passionate; they're unfree. Their mind is agitated, their soul is clogged.
Context matters. Lavater wrote in an 18th-century Protestant world that treated inner life as a battlefield where virtues and vices compete for the will. His era is edging toward modern psychology, but he insists on moral accountability. The subtext is pastoral and disciplinary: if jealousy is demonic and numbing, it can't be justified as love, instinct, or righteous vigilance. It's a spiritual counterfeit that mimics intensity while quietly eroding the person who indulges it.
