All Hell is smaller than one pebble of your earthly world: but it is smaller than one atom of this world, the Real World [Heaven]. Look at yon butterfly. If it swallowed all Hell, Hell would not be big enough to do it any harm or to have any taste…. [A]ll loneliness, angers, hatreds, envies and itchings that it contains, if rolled into one single experience and put into the scale against the least moment of the joy that is felt by the least in Heaven, would have no weight that could be registered at all. Bad cannot succeed even in being bad as truly as good is good.
