 People respond in various ways after grasping the diversity of the models. Some abandon the models altogether, either exhausted by their complexity (embodied in Watt’s wonderful phrase “the which than which there is no whicher”, 1972: 110), or convinced by their number and inconsistency that some models logically must be making a mistake, and it will be very hard to tell which ones. In other words, one response to the diversity is to decide more deeply that the nature of what is ultimate is indeed beyond us, if there is anything ultimate at all, so it is not worth thinking about it.
