  The first ten chapters of the Foundations provide the epistemology, metaphysics and theorizing on scientific methodology that is meant to provide the foundations for the remaining chapters on Newtonian physics. An evaluation of the success of that seemingly paradoxical project must await a much more sustained treatment than can be given here.  Rather, in this final section of this survey of Du Châtelet's natural philosophy, we focus on one chapter of that later material both to show ways in which the earlier chapters affect those that follow, and to show the limits to the characterization of Du Châtelet as a metaphysical  systematizer.[27]  This chapter is chapter 16: On Newtonian Attraction.
