Locke and Leibniz on Substance gathers together papers by an international group of academic experts, examining the metaphysical concept of substance in the writings of these two towering philosophers of the early modern period. Each of these newly-commissioned essays considers important interpretative issues concerning the role that the notion of substance plays in the work of Locke and Leibniz, and its intersection with other key issues, such as personal identity. Contributors also consider the relationship between the two philosophers and contemporaries such as Descartes and Hume

This volume is a critical edition of the eight-year correspondence between Gottfried Wilhelm Leibniz and Burcher de Volder, professor of philosophy and mathematics at Leiden University. Containing the surviving correspondence between Leibniz and De Volder, the volume also presents a generous selection from the letters between Leibniz and his friend Johann Bernoulli, through whose intercession the correspondence began. Bernoulli acted as intermediary throughout, and the often candid discussions between Leibniz and Bernoulli provide illuminating background to the correspondence proper. Each of the selections appears both in the original Latin and in English translation

It has become something of a received view among contemporary scholars that Leibniz first adopted the pre-established harmony around the time of the Discourse on Metaphysics and Correspondence with Arnauld, i.e., 1686-87. However, in their recent contribution to the Cambridge Companion to Leibniz, Christia Mercer and Robert Sleigh Jr. have challenged this orthodoxy by claiming that Leibniz was committed to the doctrine, in all but name, by April 1676. In the present paper, I argue that the evidence that Mercer and Sleigh present to support their somewhat radical thesis is problematic in a number of respects. But rather than embracing the ‘received view’, I present further evidence in favor of the view that Leibniz had in fact adopted the pre-established harmony by 1679.
