If you’re curious to learn more about what Catarina Dutilh Novaes called conjunctive pluralism (as opposed to disjunctive pluralism), take a look at some of her blog posts from NewAPPS:
Methodological Pluralism in Philosophy
Intuition-based Philosophical Methodology and Belief
Empirically-informed Philosophy of Logic
Feynman on Precise Definitions and Philosophical Methodology
On the Origins of Analytic Philosophy
Instrumentalist and Intrinsic Value Defenses of History of Philosophy
History of Philosophy as Antidote to Philosophical Intuitions
In addition, keep your eyes out for her forthcoming book, in which she applies a combination of the methods we talked about to investigate the status of formal languages as a part of the philosopher’s toolkit:
