You are so careful of your boy's morals, knowing how troublesome they may be, that you keep him away from the Venus of Milo only to find him in the arms of the scullery maid or someone much worse. You decide that the Hermes of Praxiteles and Wagner's Tristan are not suited for young girls; and your daughter marries somebody appallingly unlike either Hermes or Tristan solely to escape from your parental protection. You have not stifled a single passion nor averted a single danger: you have depraved the passions by starving them, and broken down all the defences which so effectively protect children brought up in freedom.
