Summary

Guatemalan-American philosopher who contributed to the theory of indexicals (quasi-indexicals) and developed guise theory — a comprehensive ontology of propositional attitudes.

Core Contribution

Quasi-indexicals: sentences reporting others' thoughts about themselves cannot be captured by standard indexicals or names — 'He believes he is the best' — requiring a new logical category. Guise theory: objects are bundles of guises (properties-as-instantiated); propositional attitudes relate agents to guises. Founded the journal Noûs.

Key Spikes & Highlights

  • Quasi-indexicals: the first-person pronoun 'I' in reported thought is irreducible to names or descriptions. 'Oedipus believes that he himself is Jocasta's son' cannot be paraphrased using 'Oedipus' in place of 'he himself' — a fundamental point about self-knowledge.
