I know of the Vic Stenger (laws-from-symmetry) approach (from the old Atoms and the Void group). *The Comprehensible Cosmos: Where Do the Laws of Physics Come From?* https://books.google.com/books/about/The_Comprehensible_Cosmos.html?id=09sPAQAAMAAJ It's possible that the "laws" of nature - physics, chemistry, biology, psychology, ..- can come from a single simplicity, or that it's more of a babel - like the theoretical sciences suggest - with theoretical physics, chemistry, biology having separate vocabularies, frameworks, and theories. - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
