Mathias Frisch (Maryland) gives a talk at the MCMP/MCTS Workshop on Laws of Nature (17 December, 2012) titled "Why Physics Can't Explain Everything". Abstract: Barry Loewer and David Albert have argued for a view on laws that is at once pragmatic (and takes nomic regularities are summaries of aspects of the Humean mosaic that are useful for beings like us) and 'imperialistic' or foundationalist. I argue in this paper that there is a deep tension between the two planks of the account and suggest that it is the pragmatism and not the foundationalism that is worth keeping.
