In Shakespeare's plays, the "Fools" are often the only characters willing to speak the truth in defiance of conventional wisdom/majority opinion.

"JESTER, n. An officer formerly attached to a king's household, whose business it was to amuse the court by ludicrous actions and utterances, the absurdity being attested by his motley costume. The king himself being attired with dignity, it took the world some centuries to discover that [The King's] own conduct and decrees were sufficiently ridiculous for the amusement not only of his court but of all mankind. The jester was commonly called a fool, but the poets and romancers have ever delighted to represent him as a singularly wise and witty person. "
