He provides a careful and deliberate exposition following Kant's own order of argument; hence the book is divided into four main chapters, devoted in turn to Kant's Phoronomy, Dynamics, Mechanics, and Phenomenology.
55) In the Phoronomy chapter Kant investigates the concept of motion as a space-time quantity; in the Dynamics he considers the filling of a space as a quality of outer perception; in the Mechanics chapter the concepts of certain spatial and dynamical relations are introduced; and in the fourth and final Phenomenology chapter he examines the concept of motion, treating it as a modality of the cognition of matter.
This is why Kant's phoronomy does not allow us to determine the existence of a single motion in nature, but has as its "sole principle" a thesis concerning the manner in which the (empirically given) motion of a body may be represented as a composite of two or more motions.
The implications of the empirical status of motion reach beyond the phoronomy chapter.
The Phoronomy and the Mechanics do not determine the existence of a single motion in nature but only provide rules for the mathematical construction of motions, in the first case, and the (idealized) deduction of consequent motions from antecedent (empirically given) motions, in the second.
To construct a repulsive force is just to represent the motion of a second body as a composite of two opposed motions in accord with the procedure set out in Kant's phoronomy.
Accordingly, they provide a substantial overview of the Phoronomy, Dynamics, Mechanics, and Phenomenology (together with an intriguing account of their interdependence).
