Acknowledgments

This project would not have been possible without the wonderful vision and generous support of the Polonsky Academy and the Polonsky family. I’d like to thank Tim Button, Geoffrey Hellman and Hartry Field for their detailed and generous feedback on parts of this book. I’d also like to thank Jared Warren, Tom Donaldson, Zeynep Soysal and Dan Waxman for much delightful philosophical argument over the internet. Going back further, I’d like to thank my dissertation advisors Warren Goldfarb, Peter Koellner, Ned Hall and Bernhard Nickel; my graduate school friends Jon Litland, Eylem Özaltun and James Shaw; and my former colleagues at the Polonsky Academy for Advanced Study and the ANU, especially Silvia Jonas, Casper Storm-Hanson, Olla Solomyak, Dave Chalmers, Daniel Nolan and Ray Briggs. Finally, I’d like to thank my dear husband Peter Gerdes for endless mathematical writing advice and lively philosophical debate, and my parents Edward and Li-shar Berry.

This book is dedicated to Robert Berry my beloved grandfather and first philosophical interlocutor, in memory of many long arguments. His stubborn curiosity, kindness and quest for rigor are an inspiration to me.
