“Locke and His Followers” 3

This is Part 3 in an exploration of Leibniz’s complaint about “Locke and his followers” in his letter to Caroline (part of the “Leibniz-Clarke” correspondence). What is the problem that Leibniz sees with British philosophy circa 1714? In addition to the problems raised against Newton and his followers, what goes mostly unexplored in the Leibniz-Clarke-Caroline correspondence is the problem with the materiality and natural mortality of the soul because Clarke, too, is opposed to both the materiality and natural mortality of the soul.

Part 2: Catherine Trotter Cockburn

In 1696, John Toland published Christianity Not Mysterious, raising both his international profile and his notoriety. This was followed by multiple tracts—including, importantly, defenses of republicanism, of the Hanoverian succession, and of the importance of securing Protestant rule in England—before his 1704 Letters to Serena. His pamphlets in support of the Hanoverian succession secured him a spot in the envoy to welcome Frederick, Sophie, Sophie Charlotte, and Caroline. This greatly developed his international network and resulted in a series of debates with Leibniz, which may have served as a basis for Letters to Serena (where Sophie Charlotte is a plausible candidate for the pseudonymous “Serena”).

This is important for our purposes in that it gave Leibniz an opportunity to meet a British philosopher in whom he saw the destructive elements left open by Locke’s failure to condemn thinking matter. Leibniz held a very low opinion of Toland’s philosophical and historical abilities. (He told Sophie that Toland “likes to make grand discourses; in a word, he wants to be an author. … Instead of dabbling in philosophy, which is not his forte, he would do better to restrict himself to the search for facts.” [Strickland, Leibniz and the Two Sophies, 291]) Leibniz, though, took Toland’s views to be important enough that he wrote down multiple lengthy letters for Sophie Charlotte refuting Toland’s views even after he had debated the points in her presence previously. His “Letter on what is independent of sense and matter” went through multiple drafts and culminated in an argument that there are immaterial substances that are outside of matter. (See Strickland’s Leibniz and the Two Sophies, 220ff, esp. 233-236 and 245-247.) Sophie Charlotte passed Leibniz’s letter to Toland, who responded, partly by side-stepping the issue of immortality of the soul by saying he only ever meant to discuss the “present state.” Leibniz again goes through multiple drafts in composing a response. Leibniz and Toland also corresponded directly, including Leibniz’s essay known as “Reflections on the doctrine of a single universal spirit,” which emphasizes the importance of individual souls.

Toland should certainly be included among “Locke and his followers,” despite Locke’s desire to be disassociated from Toland’s notorious religious and political views. Leibniz certainly was distressed by Toland’s views and perhaps also Sophie Charlotte’s openness to his views.
