Plato

“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 it 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, Phaedrus

“The highest mountain, the oldest books, the strangest people, there you will find the stone.”
― Athanasius Kircher

“I think for anyone to become good at something, they have to fail a lot too. And they have to be completely unafraid to fail or they'll never make it to the next level.”
