 Within the descriptive project we can distinguish two different ways of engaging with the fit-with-physics question. Most obviously (and what is more prominent in the philosophical literature) we can propose a conceptual analysis of our intuitive, commonsense notion of cause and then ask whether and to what extent the analysans also plays a legitimate role in physics. For example, we might ask to what extent Lewis’s notion of causal dependence analyzed in terms of time-asymmetric counterfactual dependence plays a role in reasoning in physics. As we will see below, prominent arguments denying that causal notions fit with physics are most plausibly understood as engaging in this version of a descriptive project.
