The grounding revival brought metaphysics back without bringing back a method
For much of the twentieth century, substantive metaphysics was out of fashion. Carnap argued that many ontological questions were either trivial within a framework or merely practical choices about which framework to use. Quine brought ontology back, but in a tightly regimented…

Logical pluralism is right, for the same reason statistical pluralism is
I build credit-scoring models in Nairobi. In my field the old fight between frequentist and Bayesian statistics has mostly cooled into pluralism: each is legitimate, they answer different questions, and a good analyst knows which to use when. I think logic is…
