Agustin Rayo (updated)

Agustin Rayo is going to give a series of lectures at the ENS : "On Possibility and Content".
Dates and venue :
- mercredi 7, 10h à 12h, salle de réunion IJN-LSCP (au 29 rue d'Ulm, 75005 Paris)
-mardi 13, 10h à 12h, salle Weil (au programme: 'Broad Content')
-mercredi 21, 10h à 12h, salle de réunion IJN/LSCP, 29, rue d'Ulm.
-mardi 27, 10h à 12h, salle Weil

Abstract:
The seminar will be on possibility and content. I will argue that these two notions are closely related, and cannot be understood independently of one another. The core idea can be stated simply: to describe a sentence's truth-conditions is to explain how the world must be in order for the truth-conditions to be satisfied. But it has far reaching consequences. I will argue that it can help address puzzles in modal epistemology, ontology and vagueness.
The seminar will draw on material from a book manuscript I am working
on, which is based on the following papers:
A account of possibility
A actualist's Guide to quantifying in
On specifying truth-conditions
Vague Representation
For a more user-friendly introduction to some of the main themes of
the seminar, I recommend:
