"An optimist may see a light where there is none, but why must the pessimist always run to blow it out?"
About this Quote
Descartes turns a tidy personality quiz - optimist versus pessimist - into an ethical accusation. The line is built like a trap: first it grants the optimist a flaw (seeing light where there is none), then pivots to a sharper question that makes the pessimist look not merely cautious but actively destructive. That "run" matters. It suggests haste, a compulsion, a kind of moral cardio: the pessimist is not patiently correcting error but sprinting to snuff out possibility. The image of blowing out a light is domestic and intimate, not grandiose; pessimism becomes the petty tyrant of the room, not the wise sentinel on the wall.
The subtext is recognizably Cartesian even if the quote’s exact provenance is debated: doubt is valuable as a method, disastrous as a temperament. Descartes made skepticism productive by disciplining it - doubt everything, but for the sake of rebuilding knowledge on firmer ground. This aphorism draws a line between epistemic humility and performative negation. The optimist may hallucinate a candle; the pessimist, in this framing, is the person who can’t tolerate anyone else groping toward warmth, direction, or hope.
Culturally, it’s also a jab at a certain status economy: cynicism often passes as intelligence because it can puncture almost anything. Descartes flips that prestige. He implies the real philosophical failure isn’t being wrong in the direction of hope; it’s making other people’s hope your problem to extinguish.
