Kripke fixed-point theory of truth

Target entity: Kripke fixed-point theory of truth
Context triple: [liar paradox, addressedBy, Kripke fixed-point theory of truth]

• A. Tarski's undefinability theorem
  Tarski's undefinability theorem is a fundamental result in mathematical logic showing that, in sufficiently strong formal systems, the notion of truth for the language of the system cannot be defined within that same language.
• B. The Logical Syntax of Language
  The Logical Syntax of Language is Rudolf Carnap’s seminal 1934 work that systematically develops a formal, logical framework for analyzing the structure and rules of scientific languages, helping to found logical empiricism and modern philosophy of language.
• C. Tarskian object-language/metalanguage distinction
  The Tarskian object-language/metalanguage distinction is a foundational semantic framework that separates the language in which statements are made from the higher-level language used to talk about and define their truth, thereby avoiding self-referential paradoxes like the liar paradox.
• D. Remarks on the Foundations of Mathematics
  Remarks on the Foundations of Mathematics is a posthumously published collection of Ludwig Wittgenstein’s later writings that critically examines the nature of mathematical truth, proof, and practice from a philosophical and language-centered perspective.
• E. The Logical Structure of the World
  The Logical Structure of the World is Rudolf Carnap’s seminal 1928 work in which he develops a rigorous, formal reconstruction of all scientific concepts from a phenomenalist basis, serving as a foundational text of logical positivism.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Kripke fixed-point theory of truth
Target entity description: The Kripke fixed-point theory of truth is a semantic framework developed by Saul Kripke that uses partial truth predicates and fixed points to consistently handle self-referential sentences and semantic paradoxes like the liar paradox.
