"The personal mystery of medieval man has been largely destroyed by capitalistic technicism and bourgeois scientism. There was always something mystical in personal creation as well as a "secret" in manual, artistic skills; convents and monasteries jealously kept the secret of their liquors; craftsmen had their secrets and so had doctors, alchemists, astrologers, and pharmacists in their more or less dark trades. Mystics, hermits, midwives, cooks, and violin builders harbored their secrets. Nature was full of unpenetrable mysteries and strange events; the scarcity of written documents furthered the growth of sagas, folklore, and legends."
