 Woodward (2014) distinguishes “how does causation fit with physics” as a separate philosophical project on a par with the metaphysical, descriptive, and functional projects. Yet the question concerning the fit with physics is best thought of as a question to be addressed within each of the three projects. Indeed, philosophical discussions examining the fit of causal notions with physics can benefit from distinguishing carefully—and perhaps more carefully than it is often done—among the different projects within which the discussions take  place.[2]
