Query: The dynamics of difference   A proposal is made for a fundamental theory, in which the history of the
universe is constituted of diverse views of itself. Views are attributes of
events, and the theory's only be-ables; they comprise information about energy
and momentum transferred to an event from its causal past. A dynamics is
proposed for a universe constituted of views of events, which combines the
energetic causal set dynamics with a potential energy based on a measure of the
distinctiveness of the views, called the variety. As in the real ensemble
formulation of quantum mechanics, quantum pure states are associated to
ensembles of similar events; the quantum potential of Bohm then arises from the
variety.
