"I just don't see how positing or something else, as long as it's literally a scientific posit that's supposed to make things happen, gets you any place," he says. "The same kind of question arises about whatever it is that you posited ... And it is like it or not." Theist will say, I can explain this feature of the world by invoking God, but then you haven't explained where God came from and the laws of physics are in an analogous situation here. Einstein was preferring the second of Rose.

The founders of statistical mechanics in the 19th century faced an uphill battle to convince their fellow physicists that the laws of thermodynamics could be derived from the random motions of microscopic atoms. This insight turns out to be even more important than they realized: the emergence of patterns characterizing our macroscopic world relies crucially on the increase of entropy over time. Barry Loewer has (in collaboration with David Albert) been developing a theory of the Mentaculus — the probability map of the world — that connects microscopic physics to time, causation, and other familiar features of our experience.
