 The preceding could be said for many subjects apart from epistemology. Indeed, mathematical method may facilitate progress on questions specific to epistemology, much as it has on questions specific to physics or economics. And excessive allegiance to a particular formalism has pitfalls in physics and economics, just as it does in epistemology. If we left the matter there, however, we would not do justice to the unique ambitions that have been framed for mathematical method in epistemology in particular.
