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.

This paper illuminates Leibniz’s conception of faith and its relationship to reason. Given Leibniz’s commitment to natural religion, we might expect his view of faith to be deflationary. We show, however, that Leibniz’s conception of faith involves a significant non-rational element. We approach the issue by considering the way in which Leibniz positions himself between the views of two of his contemporaries, Bayle and Locke. Unlike Bayle, but like Locke, Leibniz argues that reason and faith are in conformity. Nevertheless, in contrast to the account that he finds in Locke’s Essay, Leibniz does not reduce faith to a species of reasonable belief. Instead, he insists that, while faith must be grounded in reason, true or divine faith also requires a supernatural infusion of grace.
