Mundus vult decipi, ergo decipiatur, a Latin phrase, means "The world wants to be deceived, so let it be deceived."
According to the Great Norwegian Encyclopedia, the phrase is first documented in Sebastian Brant's Das Narrenschiff (1494), in the form "Die weltt die will betrogen syn".
[1] It notes that it has since continuously been ascribed to older writers.
Various claims have been made as to the phrase's origin: Some claim that the 1st century satirist Petronius originated this expression, but it appears nowhere in the surviving copies of his work.
