2000 Ted Sider, xt. The topic of this seminar is reductive theories of modality.
Modalities provide many philosophical challenges.
We'll begin by discussing parts of David Lewis's book On the Plurality of Worlds, which is out of print. I've xeroxed the relevant bits, which are in the TA room. If you can acquire a used copy of this contemporary classic, I would recommend doing so. We'll then discuss parts of D. M. Armstrong's A Combinatorial Theory of Possibility, which is only available in hardback. Anyone who wants to order a copy should let me know, and I'll tell the bookstore how many copies to order.
