The impetus for this book arose from two recent graduate seminars of
mine at Princeton University . The first was a year-long seminar on Nam-
ing and Necessity and its aftermath jointly taught by David Lewis and me
in the 1999–2000 academic year . At the first meeting, David announced
that although the work of Kripke and other anti-descriptivists was often
regarded as revolutionary, he himself was a counterrevolutionary . Accord-
i
ngly, during the course of the year, he developed a version of two-dimen-
sionalist descriptivism, and used it to accommodate and reinterpret central
Kripkean doctrines and examples—while adhering to an essentially pre-
Kripkean conception of meaning, belief, and modality . I was on the other
side, having announced at the first meeting that the anti-descriptivist rev-
olution begun in the 1970s by Kripke, Kaplan, Putnam, and others was a
genuine advance that needed to be pushed even further .
For me the sem-
inar was extraordinarily productive. I benefited not only from David’s
inspired and often brilliant presentation of the opposing v iew, but also
from the active participation of a number of accomplished graduate stu-
dents and professors who regularly attended the meetings—includi ng,
among others, Cian Dorr
, Mike Fara, Kit Fine, Delia Graff, Jonathan
McKeown-Green, Benj Helle, Sean Kelly, Mark Johnston, Michael Nel-
son, and Jeff Speaks. The second major occasion on which I dealt with
these issues was my seminar on two-dimensionalism in the spring of 2003.
There I presented, in skeletal for m, all the main themes developed more
fully in this book. A gain, I benefited from the co mments of an exception-
ally acute group of graduate students and professors fr
om Princeton and
Rutgers, including Eliza Block, Alexis Bur gess, Sam C umming, David
Gordon, John Hawthorne, Jeff Kepple, Sarah-Jane Leslie, Stephen Leu-
enberger, David Manley, Mike McGlone, Jim Pryor, Dan Rothschild,
Gillian Russell, Mark Schroeder, Adam Sennet, Brett Sher man, Ted Sider,
and Jeff Speaks.
In addition to presenting material on two-dimensionalism at these se m-
inars, I gave several lectures on the s
ubject, first at the University of Cal-
gary and the University of California, Los Angeles, in the fall of 2002, and
then at Wayne State University, the University of Connecticut, the Uni-
versity of Massachusetts, and the University of Southern California, as
well as at conferences in Bir mingham, England, Barcelona, Spain, and
Portland, Oregon, in 2003. A mong the many who attended my lectures
