A Kripkean Theory of Truth for Unrestricted Higher-Order Languages

  • Simon Schmitt

摘要

This paper develops a Kripkean truth theory for higher-order languages that is compatible with absolute generality. Existing accounts either omit truth-theoretical elements (Rayo and Uzquiano in Notre Dame J Formal Logic 40(3):315–325, 1999) or focus only on first-order languages (Rossi in Notre Dame J Formal Logic 64(1):95–127, 2023). To fill this gap, I generalize existing literature to cover unrestricted higher-order languages and develop an absolutist-friendly interpretation of higher-order expressions. The theory models key features of natural language, including categorical reference to mathematical structures, a type-free truth predicate, and generality absolutism.
