In this paper, we explore whether contrasting views about the explanatory value of proof are possible and how to understand these diverging … WebbSolutions to semantic paradoxes often involve restrictions of classical logic for semantic vocabulary. In the paper we investigate the costs of these restrictions in a model case.

Webb9 mars 2024 · A proof is a series of statements, starting with the premises and ending with the conclusion, where each additional statement after the premises is derived from … Proof theory is a major branch of mathematical logic that represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques. Proofs are typically presented as inductively-defined data structures such as lists, boxed lists, or trees, which are constructed according to the axioms and rules of inference of the logical system. Consequently, proof theory is syntactic in nature, in contrast to model theory, which is semantic in nature.
