Logical pluralism posits that multiple, equally valid logics exist, each capturing different facets of reasoning and argumentation. It challenges the…
Löb's paradox, a puzzle in modal logic, questions the formalization of provability within a system. It leads to counterintuitive results…
A Kripke structure is a mathematical model representing systems with multiple states and transitions. It's fundamental to Kripke semantics in…
A formal framework for modal logic using possible worlds. Developed by Saul Kripke, it enables rigorous analysis of necessity, possibility,…
A logic designed for higher-order quantification and modalities. It emerged from discussions on the foundations of mathematics by Kreisel and…
A paradox where the truth of a statement implies its knowability. This epistemic puzzle, particularly in modal logic, raises questions…
