 So its method is focused on analysing the causes of motions in terms of forces, a quantifiable natural kind that is defined in terms of other quantities. So defined, the problem cries out for a mathematical apparatus, and so it fosters what I.B. Cohen termed “the Newtonian style” in philosophy: taking mathematics as the model of reality, constructing “the mathematical analogue of a natural situation”, and then producing from this idealized case by the addition of further conditions more and more accurate mathematical analogues of actual situations (Cohen 1980: 51, 151). Through this series of “successive approximations”, Newton’s axioms or laws of motion function as “inference tickets” that allow for drawing conclusions from motions to forces and vice versa, and also from macrophysical to microphysical forces composing them (Smith 2002: 143, 155–159; Smeenk &amp; Schliesser 2013).
