Hyperintensionality Challenges Standard Possible-World Semantics Accounts
An excerpt analyzes hyperintensional phenomena in philosophy of language and mind, distinguishing representational (belief, knowledge, propositions) and non-representational notions (essence, grounding, truthmaking). It highlights problems for standard possible-world semantics—logical omniscience, uninformative necessary truths, and failure to distinguish necessarily equivalent contents—using examples like knowledge, Fermat’s Last Theorem, and conditionals. The analysis implies need for hyperintensional individuation or alternative semantic frameworks.
Key Points
- 1Showcases diverse hyperintensional phenomena across representational and non-representational philosophical concepts.
- 2Identifies failures of standard possible-world semantics, e.g., logical omniscience and uninformative necessary truths.
- 3Implies need for hyperintensional individuation or alternative semantic frameworks for practitioners and theorists.
Scoring Rationale
Solid theoretical survey with credible scholarship, but limited immediate practical impact and incremental novelty overall.
