At a recent conference I gave a paper on Leibniz’s correspondence with Thomas Burnett of Kemnay. Among my questions was how Locke appeared to Leibniz. Did he look like a Socinian, or similar sort of religiously dubious character? In answering that, it would be good to have some idea of how Leibniz thought about Locke’s Reasonableness of Christianity. But Leibniz said relatively little explicitly about that text. There is, however, an argument in Leibniz’s correspondence with Burnett that seems to bear on the issue.
It seems to me that too many books aiming to prove the truth of religion are written in your country. That’s a bad sign, and is something that doesn’t always have a good effect … I have often thought, and others have come to agree with me, that preachers should usually avoid this issue, because instead of relieving doubts, they give rise to them. Books in vernacular languages have this effect most often … I’d prefer that we concentrated on making the wisdom of God known through physics and mathematics, by revealing more and more of the wonders of nature. That’s the real way to convince the profane, and should be the goal of philosophy (Leibniz to Burnett, 18 July 1701, A 1.20.185, pp.286-7).
