"I think I won the same wavelength. Even though the UMean doesn't think of the laws as extra ontological entities that are governing anything, we can still figure out what the laws are," he says. "They're just employing our ordinary notions of causation and using as though they understand it applying there." The right way to think about laws is not as explaining by producing. They explain mostly by unifying,. What the laws do is they unify.

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.
