“The greatest trick the devil ever pulled was convincing the world he didn't exist.”
This is the wording from the 1995 film The Usual Suspects, spoken by Kevin Spacey's character. Baudelaire wrote something close in “Le Joueur généreux,” a prose poem in Le Spleen de Paris: the devil's finest ruse is to persuade you that he does not exist. The idea is his; the famous sentence is the screenwriter Christopher McQuarrie's.
