Life & Wisdom Quote by Francois de La Rochefoucauld

Jealousy, in La Rochefoucauld's hands, isn’t a fiery passion so much as a parasite with a strict diet: uncertainty. The line has the cool, surgical cruelty of a writer who made a career out of puncturing noble self-images. Jealousy doesn’t “live upon love,” he implies; it lives upon the mind’s inability to close the case. Doubt is the oxygen. Starve it with certainty and the thing either dies (if the fear was unfounded) or mutates into something more catastrophic (if the fear is confirmed).

That binary ending - “madness or ceases entirely” - is the real trick. It refuses the sentimental idea that clarity brings peace. Certainty is not comfort; it’s an accelerant. If you learn the betrayal is real, jealousy doesn’t get resolved, it gets promoted into obsession, rage, or despair. If you learn it isn’t, jealousy vanishes not because you’ve become wiser, but because its fuel line has been cut. La Rochefoucauld is quietly mocking our moral narratives: the emotion isn’t noble, it’s mechanical.

The context is a courtly world built on performance, gossip, and reputations that could be revised overnight. In that environment, doubt isn’t an unfortunate side effect; it’s the social weather. The subtext is cynical and modern: jealousy is less a measure of devotion than a measure of interpretive instability - the inability to tolerate not knowing. In a culture of surveillance and half-evidence, the quote lands as a warning: ambiguity doesn’t just hurt; it sustains the very torment we claim to want to escape.
