I think we want the notion of science, of laws to be mind dependent in a sense. It's something that we've concocted in order to account for the facts. So it's not subjectivist or unrealistic in this bad way. And it's my view about what's macroscopic, what counts as a macroscopic state too. But fitting us all together in one giant package is something that I don't know how to do.
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.
