Many native traditions held clowns and tricksters as essential to any contact with the sacred. People could not pray until they had laughed, because laughter opens and frees from rigid preconception. Humans had to have tricksters within the most sacred ceremonies for fear that they forget the sacred comes through upset, reversal, surprise. The trickster in most native traditions is essential to creation, to birth.
SF has at least the advantage of not depending on preconceptions.
