If this was not so clear in the previous letter I read, Bolingbroke has studied his s—t. He has named dropped in such a way that it’s clear he’s read them well Bacon, Descartes, and Leibniz.

My understanding is that Pope turned to Bolingbroke for philosophical counsel when writing his great Essay on Man. But no one has ever accused that poem of having more than moderate philosophical value (but great poetic value). Neither does Pope’s friend, whose philosophy seems to be, at its heart, Baconian, mixed with a dose of anti-clericalism (though knowing what I know, I expect that Anglican ministers are exempt from his rhetorically flourishing vitriol). He gets in a jab at Leibniz (which he spells Leibnitz):

Leibnitz, one of the vainest and most chimerical men that ever got a name in philosophy, and who is often so unintelligible that no man ought to believe he understood himself…
Good stuff, eh?
