As Peret asserts, the value of such stories resides in the fact that they respond to direct social necessity but in a way that is not obvious in a society dominated by what is utilitarian and functional. Rather they represent a natural surplus of imaginative abundance that may confound or reinforce the way we perceive the world, but which never does so in a simple way. Even though they may have no direct social use, they nonetheless embody the actual state of real relations between people.
