Lavoisier—the Crucial Year: The Background and Origin of His First Experiments on Combustion in 1772

The author explores the origins of the eighteenth-century chemical revolution as it centers on Antoine-Laurent Lavoisier's earliest work on combustion. He shows that the main lines of Lavoisier's theory—including his theory of a heat-fluid, caloric—were elaborated well before his discovery of the role played by oxygen. Contrary to the opinion prevailing at that time, Lavoisier suspected, and demonstrated by experiment, that common air, or some portion of it, combines with substances when they are burned. Professor Guerlac examines critically the theories of other historians of science concerning these first experiments, and tries to unravel the influences which French, German, and British chemists may have had on Lavoisier. He has made use of newly discovered material on this phase of Lavoisier's career, and includes an appendix in which the essential documents are printed together for the first time

Newton and Wolff: The Leibnizian Reaction to the Principia, 1716-1763

Newton rested his theory of mechanics on distinct metaphysical and epistemological foundations. After Leibniz's death in 1716, the Principia ran into sharp philosophical opposition from Christian Wolff and his disciples, who sought to subvert Newton's foundations or replace them with Leibnizian ideas. In what follows, I chronicle some of the Wolffians' reactions to Newton's notion of absolute space, his dynamical laws of motion, and his general theory of gravitation. I also touch on arguments advanced by Newton's Continental followers, such as Leonhard Euler, who made novel attempts to defend his mechanical foundations against the pro-Leibnizian attack. This examination grants us deeper insight into the fate of Newton's mechanics on the Continent during the early eighteenth century and, more specifically, sheds needed light on the conflicts and tensions that characterized the reception of Newton's philosophy of mechanics among the Leibnizians

Descartes, spinoza, and the impasse of french philosophy: Ferdinand alquie versus martial gueroult

This article presents a decades-long conflict in the upper echelons of postwar French academic philosophy between the self-identifying “Cartesian” Ferdinand Alquié, professor at the Sorbonne, and the “Spinozist” Martial Gueroult of the Collège de France. Tracking the development of this rivalry serves to illuminate the historical drama that occurred in France as phenomenology was integrated into the Cartesian tradition and resisted by a commitment to rationalism grounded in a specifically French understanding of Spinozism. Over the course of Alquié and Gueroult's polemic, however, we nevertheless witness a shared concern to preserve philosophy from the reductive tendencies of historicism and its possible assimilation to theology. What is more, the ultimate impasse of this conflict continues to inform the most innovative projects in French thought in the wake of structuralism and the “theological turn” of French phenomenology
