"Legal fiction is the mask that progress must wear to pass the faithful and bleared-eyed watchers of our ancient legal treasures. But though legal fictions are useful in this mitigating or absorbing the shock of innovation, they work havoc in the form of intellectual confusion. The least that can be said is that they tend to make us all ignore the magnitude and character of the actual changes wrought by them. The mask shuts off a great deal of needed light"
