Query: The metaphysics of laws: dispositionalism vs. primitivism   The paper compares dispositionalism about laws of nature with primitivism. It
argues that while the distinction between these two positions can be drawn in a
clear-cut manner in classical mechanics, it is less clear in quantum mechanics,
due to quantum non-locality. Nonetheless, the paper points out advantages for
dispositionalism in comparison to primitivism also in the area of quantum
mechanics, and of contemporary physics in general.
