Reasoning about truth: Gupta's puzzle as a case study
Abstract: Examples of reasoning taken from ordinary language are often employed in the philosophical debate to sustain arguments in favour or against theories of truth and paradox. Is the rationale behind these uses of logic puzzles either normative or descriptive? By taking from the field of formal theories of truth a paradigmatic example – Gupta’s puzzle – as our case study, we will argue that the answer to the above question cannot be simply either “purely normative” or “purely descriptive”, rather we will point to a necessary and fruitful interplay between normative and descriptive aspects of such kinds of philosophical investigation.
