SUMMARY:Ed Zalta: How to Ground Semantics in Highe
 r-Order Metaphysics, Ed Zalta
ATTENDEE;ROLE=Speaker:Ed Zalta (Stanford)
DTSTART;TZID=Europe/Amsterdam:20260617T160000
LOCATION:ILLC Seminar Room F1.15, Science Park 107
  
DESCRIPTION:It is our great pleasure to announce a
  talk by Ed Zalta (Stanford) taking place at the I
 LLC. Ed is the creator of the famous Standford Enc
 yclopaedia of Philosophy and well-known for his ab
 stract object theory. He is a very accessible pers
 on who loves to talk to students, so this should b
 e a great opportunity for our students.   Abstract
 : In this talk, I show how the primitive notions o
 f semantic theories, and the principles stipulated
  in the semantics to govern these notions, can be 
 systematically defined and derived in object theor
 y (OT). For example, philosophers and logicians ha
 ve postulated possible worlds, impossible worlds, 
 situations, possibilities, truthmaker states, HYPE
  states, plural entities, etc. as part of their se
 mantic interpretation of natural language. They al
 so assert axioms that govern these primitive entit
 ies. In each case, I show that in object theory, o
 ne can define the entities postulated in object-th
 eoretic terms, and then derive the axioms stipulat
 ed as theorems of object theory.  I focus particul
 ar on the two new examples of this analysis: truth
 maker states (Fine) and the possibilities used in 
 possibility semantics (Humberstone, van Benthem, a
 nd Holliday).
