Many people have contributed to this book. Friends and colleagues have helped me at every stage of research and writing, to think through issues with more depth and clarity, and to tackle some that I might otherwise have left unaddressed.
The book began as part of a doctoral thesis at Murdoch University, Western Australia. I'd like to thank friends and colleagues from that period: Pedro Tabensky, Carolyn Abbs, Antonio Traverso, Peter Kurti, and Bev Murfin, for their thoughtful ideas, advice, and support. Thanks also to the participants at seminars who listened to and commented on earlier versions of Chapters Two, Three and Four. I'd also like to thank Horst Ruthrof for helpful comments and suggestions on Chapter Three, Paula Goulding for constructive discussion of issues raised by Chapter Four, and Niels Nielson and Bruce McClintock for editorial advice and suggestions.
Peta Bowden's careful and critical reading and thoughtful, incisive comments on many earlier drafts of the manuscript helped me immensely in forming the final version, and her support for the project has been invaluable to me. Charles Altieri's and Bob White's comments on the thesis manuscript helped to persuade me that it was worth reworking for publication. The manuscript was rewritten during a research fellowship at the Centre for Applied Philosophy and Public Ethics, and I am grateful to the Centre for giving me the time to complete the task. Thanks also to the editorial team at Routledge.
Particular thanks are due to my family, parents Karen and Dick, and sisters Phillida and Oenone, who were supportive and encouraging at all stages of the writing and editing of the manuscript, and to Keith Horton, who discussed the manuscript with me and provided encouragement and much useful advice during the revision process.
