On FDE, theory closure, and related themes: responses to Calasso & Logan, Caret, Omori & Arenhart, and Standefer, Shear & French

Abstract This paper comprises responses to (in alphabetical order) Calasso and Logan (2023), Caret (2024), Omori and Arenhart (2023), and Standefer, Shear, and French (2023). Given space limitations, responses are not exhaustive; future work will engage the work further. The target papers divide roughly into philosophy of logic and strictly philosophical logic (some formal logic fueled by some philosophical issue). The former, being largely dialectical, requires more ink; the latter, except to the extent that it dips a toe into philosophy of logic, stands on its own promise and results. I am deeply honored by the contributions of each paper, and hereby thank all involved.
