 What is needed is to find ways to allow for internal heterogeneity, which would not entail that anything is “different from itself.” Here are three possibilities, the first of which is to use distributional  properties.[52]  The world might, for instance, have the property of being polka-dotted. Here there would be no question of the world being “different from itself,” or having any other problematic status. The claim that the world is polka-dotted is a coherent claim, which would entail heterogeneity among its derivative dots and background.
