"Sir," said Sir Bors, "for all a man stems from an evil stock, namely from wicked parents, this gall is changed to sweetness the moment he is anointed with the holy chrism; therefore it seems to me that it is not fathers and mothers that determine whether a man be bad or good, but his own inclinations. A man's heart is the helm of his ship and steers it where he lists, to harbour or to hazard." -- anonymous, The Quest of the Holy Grail
