" Let us be practical in our expectations of the Criminal Law.… [For] we have merely to imagine, by some trick of time travel, meeting our earliest hominid ancestor, Adam, a proto-man, short of stature, luxuriantly furred, newly bipedal, foraging about on the African savannah three million or so years ago. Now, let us agree that we may pronounce whatever laws we like for this clever little creature, still it would be unwise to pet him. "
