A number of people provided valuable feedback at various phases of this
project, and we want to acknowledge our appreciation. Five anonymous
reviewers provided helpful comments on our initial proposal. Tim Knievel
read the entire manuscript and offered detailed suggestions for improvements
in both substance and style. Kim Marten gave us insightful comments
on chapter 1 and provided additional feedback on questions arising in later
chapters.
We also want to thank the people at Wiley - Blackwell for making this
book a reality. Nick Bellorini, the Senior Commissioning Editor for Philosophy
and Politics, provided the initial encouragement. Liz Cremona, the
Senior Production Editor, supervised all phases of the project and kept the
process running smoothly. Paul Stringer did a nice job of copyediting, and
then fl awlessly incorporated our last - minute changes into the fi nal product.
We thank them all for their patience in dealing with us throughout the
process.
The authors would also like to thank each other for tolerating each
other ’ s idiosyncrasies without escalating to warfare.
