Locke’s metaphysical commitments are a matter of some controversy. Further controversy attends the issue of whether and how Locke adapts his views in order to accommodate the success of Newton’s Principia. The chapter lays out an interpretation of Locke’s commitments according to which Locke’s response to Newton on gravity does not require the positing of brute powers and is consistent with his core essentialism. The chapter raises the question of how the hypothesis concerning the creation of matter, alluded to at (...) 4.10.18, fits with these commitments. The chapter concludes that the De grav hypothesis would represent a significant revision to the background metaphysical picture of the Essay, but that nevertheless its attractions to Locke are intelligible and illuminating.

This is a preprinted excerpt from: Kochiras, “By ye Divine Arm: God and Substance in De gravitatione”, Religious Studies (Sept. 2013), 49(3): 327-356 (available at: https://www.cambridge.org/core/journals/religious-studies/article/by-ye-divine-arm-god-and-substance -in-de-gravitatione/08D21B2C2611624FA11A0D6B115849AD ). In this preprinted excerpt, I explicate the concepts of matter and space that Newton develops in De gravitatione. As I interpret Newton’s account of created substances, bodies are constructed from qualities alone, as configured by God. Although regions of space and then “determined quantities of extension” appear to replace the Aristotelian substrate by functioning (...) as property-bearers, they actually serve only as logical subjects. An implication of the interpretation I develop is that only space is extended by having parts outside parts; material bodies are spatially extended only in a derivative sense, via the presence of their constitutive qualities or powers in space.
