Duelling catechisms: Berkeley trolls Walton on fluxions and faith

ORCID Icon
 

ABSTRACT

George Berkeley is known as “The Good Bishop,” a name celebrating his faith, pastoral ministry and earnest commitment to his philosophical views. To mathematicians, he is known for his agitated performance in his 1734 critique of fluxions, The Analyst. That work and its petulant tone were occasioned by (i) his “philo-mathematical” opponents’ alleged admonitions on religious mysteries’ lack of logical respectability and (ii) what Berkeley saw as a related public appetite for reformist and deist religious movements. This paper questions Berkeley’s saintly reputation by outlining the hostility and flippancy in his handling of Jacob Walton’s contributions to the debate. Berkeley’s interactions with Walton bear many of the hallmarks of contemporary “trolling” culture and this paper emphasises and explains these parallels. Finally, given Berkeley’s theological and political agenda in his mathematical interactions, I argue that we should not read his mathematical rhetoric as straightforwardly representing his philosophical views.

Acknowledgments

I would like to thank two anonymous reviewers for some truly generous and helpful remarks on this article. Additional thanks are due to Kenny Pearce and Peter West for comments on an early version, and to Katherine O'Donnell and Francesca Bratton, for incisive feedback and exuberant enthusiasm about the idea. I am also grateful to Tom Jones for sharing some pivotal sources from his new intellectual biography of Berkeley. Final thanks to Matthew Hornsby and the editors at IHR for helping to get the article to print.

14 For example, to read The Analyst in isolation from Alciphron (which is often done by those with a predominant interest in Berkeley’s mathematical thinking) will preclude appreciation of a number of important contradictions between the texts on the issue of pragmatically useful but logically problematic concepts. As the title page of The Analyst makes clear, the text is about comparing mathematical coherence standards to those publicly afforded to religious concepts. Without Alciphron, such comparison is simply unavailable. See Reid, “Faith, Fluxions, Impossible Numbers”; Moriarty, “The ad hominem argument”.

17 The most substantial philosophical engagement with The Analyst is in Jesseph, Berkeley’s Philosophy of Mathematics. Numerous papers, recent and remote, have paid it serious attention in elucidations of Berkeley’s philosophy: Cantor, “Berkeley’s The Analyst Revisited”; Levy, “Berkeley Exorcises the Infinite”; Katz and Sherry, “Leibniz’s Infinitesimals”. The Analyst also features in more general texts examining the philosophy of mathematics, including: Mancosu, Philosophy of Mathematics; Hacking, Why Philosophy of Mathematics?; Linnebo, Philosophy of Mathematics.

18 It is worth noting that there are important differences in the theoretical underpinnings of the Newtonian and Leibnizian presentations of calculus. However, in The Analyst, Berkeley claims (controversially) that they both necessitate the invocation of entities with the same kind of metaphysical and logical issues, even if the Leibnizian account invokes them implicitly and the Newtonian account attempts to avoid them. This essay is focused on Berkeley’s rhetorical activity in this debate, so, for brevity’s sake, these equivocations will go largely unchallenged hereafter.
