Abstract

What is the role of Leibniz’s early work in the constitution of his mature philosophy? Conventional scholarship would emphasize 1686 as the point at which the Leibnizian philosophical system was in place, subsequent obscurities concerning forces and monads notwithstanding. In that year the Discourse on Metaphysics was completed, the Brief Demonstration of Leibniz’s discovery of the conservation of living force was published, and the correspondence with Arnauld begun, leading to the 1695 publication of the New System and part I of its companion Specimen Dynamicum. On this forward-looking account, the early period recedes in importance. Against this rough but established consensus, Christia Mercer argues that far more weight needs to be given to Leibniz’s early development—especially the period from 1668 to 1672—in the Aristotelian and Platonic eclecticism of seventeenth-century Germany. Daniel Garber’s advertisement on the book jacket pertains: “Though it will be controversial, her position is one that must be reckoned with.... [I]t will be read and passionately debated for years to come.”
