"And those men who are inventers and interpreters of nature to man differ from boasters and disclaimers about the works of others just as true objects differ from their reflectjons in the mirror. For the first are somthing in themselves and the others nothing--persons little indebted to nature,since it is only by accident that they are clothed,and except for this I might class them with the herds of beasts"
Leonardo Da'Vinci
