Early Newtonian Approaches to Gravitational Attraction

Patrick Connolly

Assistant Professor of Philosophy
Lehigh University

Isaac Newton’s Principia argued that gravitational forces were responsible for a number of important astronomical and terrestrial phenomena. But Newton famously refused to speculate about the cause of gravitational attraction. This talk offers a guide to some of the discussions between early Newtonians about the metaphysical underpinnings of gravitational attraction. Physicists and philosophers working in Newton’s wake developed a number of proposals to explain how gravitational forces might operate. The role played by various theological commitments in the explanations on offer will receive special attention. I will conclude with some reflections on methodology and the place of metaphysical explanation in scientific theory.
