Abstract

Most philosophers of science hold that the laws of nature play an important role in determining which counterfactuals are true. Marc Lange reverses this dependence, arguing that it is the truth of certain counterfactuals that determines which statements are laws. I argue that the context sensitivity of counterfactual sentences makes it impossible for them to determine the laws. Next, I argue that Lange’s view cannot avoid additional counterexamples concerning nested counterfactuals. Finally, I argue that Lange’s counterfacts, posited as the ultimate ontological ground for the laws of nature, are unsuited to the role he demands of them.
