Madness, provided it comes as the gift of heaven, is the channel by which we receive the greatest blessings... the men of old who gave things their names saw no disgrace or reproach in madness; otherwise they would not have connected it with the name of the noblest of arts, the art of discerning the future, and called it the manic art... So, according to the evidence provided by our ancestors, madness is a nobler thing than sober sense... madness comes from God, whereas sober sense is merely human.
Plato
