A fresh take on modal expressions like “necessary” or “possible” — blending logic, pragmatics & ontology to resolve long-standing semantic puzzles. 🔍✨
Essential reading for anyone into philosophy of language or modal logic.

Argument: Classical Modal Logic Applies to Beings, but Not to Being
Classical modal logic presupposes a space of possibilities.
This space is modelled by possible worlds, relative to which modal operators are evaluated.

The separability problem for modal fixpoint formulas is PSpace‑complete on words and ExpTime‑complete on unrestricted and binary models, with TwoExpTime‑complete hardness when outdegree ≥3. https://getnews.me/complexity-of-separating-fixpoint-formulae-in-modal-logic/ #modallogic #complexity

What is the significance of the K-axiom in modal logic S5?
In normal modal logic S5, the K axiom says $\square (p \rightarrow q) \rightarrow (\square p \rightarrow \square q)$.
First of all, is this an abuse...

It’s a cloudy and cold Tuesday, and I’m inside writing about refinement.
At least I *think* I understand what I’m doing a bit better than Mark S and his team of macrodata refiners do.

Semantical Analysis of Intuitionistic Modal Logics between CK and IK
The intuitionistic modal logics considered between Constructive K (CK) and Intuitionistic K (IK) differ in their treatment of the possibility (diamond) connective. It was recently rediscovered that some logics between CK and IK also disagree on their diamond-free fragments, with only some remaining conservative over the standard axiomatisation of intuitionistic modal logic with necessity (box) alone. We show that relational Kripke semantics for CK can be extended with frame conditions for all axioms in the standard axiomatisation of IK, as well as other axioms previously studied. This allows us to answer open questions about the (non-)conservativity of such logics over intuitionistic modal logic without diamond. Our results are formalised using the Coq Proof Assistant.

People working on non-deterministic semantics flaunt that they can do modal logic without possible worlds. But do they have a theory modality?
Yesterday in Ghent I argued that they do. Thanks for the invite, I met many people who I cite, which now I can call colleagues.
