 Causal imperialists, as we might call them, argue that all scientific explanations are fundamentally causal. Neo-Russellians, by contrast, deny that causal notions and causal explanation can play any role in suitably fundamental theories of physics. Yet, despite their stark disagreement, neo-Russellians and causal imperialists share a commitment to what Woodward has called “the hidden structure strategy” (Woodward 2003b [2019]). Both views are committed to the existence of what Peter Railton has called an “ideal explanatory text” (Railton 1981) that contains all the information relevant to a complete explanation of some phenomenon. While actual explanations may fall short of providing us with the complete information contained in the ideal explanatory text, they are explanatory, according to the hidden structure strategy, in virtue of providing us with some information about the text.
