Maupertuis, Euler, and the Leibnizian Metaphysics behind the Principle of Least Action
Abstract
Maupertuis and Euler had an ambivalent and tense relationship to their Leibniz, especially concerning his grounding of physics in metaphysics. Consequently, this paper has two intersecting goals: first, it attempts to flesh out some aspects of the reception of Leibnizian thought in the context of Enlightenment physics, more precisely, in the deduction of the Principle of least action (henceforth PLA). Second, it also highlights a specific approach towards the intersection of physics and metaphysics that was championed by the Berlin Academy, which would not have been well received in Paris or London. To that end, I will briefly examine some aspects of the strategies of argumentation, metaphysical presumptions and self-ascribed methodologies (often quite different from their actual methodology) employed by Maupertuis and Euler in their respective deductions of the PLA.
