Albert Camus said this quote

Just as there is a moment when the artist must stop, when the sculpture must be left as it is, the painting untouched—just as a determination not to know serves the maker more than all the resources of clairvoyance—so there must be a minimum of ignorance in order to perfect a life in happiness. Thosewho lack such a thing must set about acquiring it: unintelligence must be earned.
