Ebook: The main Business of natural Philosophy: Isaac Newton’s Natural-Philosophical Methodology

In this monograph, Steffen Ducheyne provides a historically detailed and systematically rich explication of Newton’s methodology. Throughout the pages of this book, it will be shown that Newton developed a complex natural-philosophical methodology which encompasses procedures to minimize inductive risk during the process of theory formation and which, thereby, surpasses a standard hypothetico-deductive methodological setting. Accordingly, it will be highlighted that the so-called ‘Newtonian Revolution’ was not restricted to the empirical and theoretical dimensions of science, but applied equally to the methodological dimension of science. Furthermore, it will be documented that Newton’s methodology was far from static and that it developed alongside with his scientific work. Attention will be paid not only to the successes of Newton’s innovative methodology, but equally to its tensions and limitations. Based on a thorough study of Newton’s extant manuscripts, this monograph will address and contextualize, inter alia, Newton’s causal realism, his views on action at a distance and space and time, the status of efficient causation in the /Principia/, the different phases of his methodology, his treatment of force and the constituents of the physico-mathematical models in the context of Book I of the /Principia/, the analytic part of the argument for universal gravitation, the meaning and significance of his regulae philosophandi, the methodological differences between his mechanical and optical work, and, finally, the interplay between Newton’s theology and his natural philosophy.

In this monograph, a historically detailed and philosophical-systematic study will be undertaken of Newton's scientific methodology. It will be shown that the hypothesis that Newton was a bad or confused methodologist is beset with many difficulties and that Newton was not a simplistic inductivist nor did he believe that causes can be derived unconditionally from phenomena. Special attention will be given to Newton’s Principia-style methodology. With respect to Newton’s Principia-style methodology, it will be shown that Newton carefully distinguished between the (physico-)mathematical treatment of force and the physical treatment of force and that the former should always precede the latter in order to uncover the forces present in rerum natura more safely. In the (physico-)mathematical treatment of force, Newton explicated the physico-mathematical conditions under which, given the laws of motion, certain motions would occur exactly or quam proxime. Of course, Newton clearly focused on those motions which would be relevant in the study of the systema mundi, i.e. Keplerian motions. It will be shown that the models of Book I are not purely mathematical, but physico-mathematical instead: the idealized motions and forces of the models of Book I are iso-nomological to real-world bodies and forces and they are analyzable by the same technical concepts, i.e. Definitions I-VIII. Given these features, Newton could bridge the gap between mathematics and physics: the physico-mathematical conditions, which are structurally similar to what would become their referents in the context of Book III, are predicated under the same laws that hold in the empirical world and, given the Definitions, one could relate certain technical terms to their quasi-physical measures.
