Nancy Cartwright's charge against horizontal reductionism leads to a claim about how the world is, namely "dappled." By proposing a simple thought-experiment, I show that Cartwright's division of the world into "nomological" machines and "messy" systems for which no law applies is meaningless. The thought-experiment shows that for a system, having the property of being a nomological machine depends on what kind of questions you ask about it. No metaphysical conclusion about the world being unruly or not can be drawn (...) from a division that is question-dependent. Moreover, I argue that this predicament undermines Cartwright's attempt to provide an illustration of how bad metaphysics of science translates into bad scientific methodologies and policies. (shrink)
