Robert Stalnaker Pufendorf Lectures in Lund 2-5 June 2009, 15-17, room 204, Kungshuset, Department of Philosophy, Lund University. The overall topic for the lectures might be titled "Mere possibilities." Titles for the individual lectures:

1. On what there isn't
   (but might have been)
2. Merely possible propositions
3. What is haecceitism, and is it true?
4. Modal semantics and modal
   metaphysics

Stalnaker’s aim is to try to get clearer about how to think about issues in modal metaphysics, and about how semantic and metaphysical issues are related.
