Humeanism and dispositionalism in physics - a podcast by MCMP Team

Michael Esfeld (Lausanne) gives a talk at the MCMP/MCTS Workshop on Laws of Nature (17 December, 2012) titled "Humeanism and dispositionalism in physics". Abstract: The paper sets out to make a case for a natural philosophy or naturalized metaphysics that treats physics and metaphysics as inseparable. It examines how Humeanism and dispositionalism about laws of nature fare with respect to classical as well as quantum physics. In particular, I argue that, despite widespread claims to the contrary, Lewis' metaphysics of Humean supervenience is applicable to non-relativistic quantum mechanics and that its application even removes the charge of quidditism. However, this position faces considerable difficulties once physics abandons the assumption of a background system of geometrical relations unifying the world. Against this background, I indicate reasons to prefer dispositionalism to Humeanism.
