JON ROBERTS is principally responsible for Part I, on the sciences, James Turner for Part II, on the humanities. But having discussed each other's successive drafts over a period of years, we have reached agreement on all substantial issues and regard ourselves as collectively responsible for the book as a whole.
Both of us wish to acknowledge the generous support of the Mellon Foundation, which provided funds that made the research for and writing of this book possible, and the even more generous assistance of John F. Wilson, who has overseen this project since its origins, giving freely of his time and intelligence, despite the demands on his energy made by his position as dean of the graduate school at Princeton University. To that university and its president Harold Shapiro and to the Mellon Foundation's president William Bowen, we are grateful for the opportunity to present early versions of this work at the conference celebrating Princeton's 250th anniversary. The many archivists and librarians who cheerfully aided our research deserve more thanks than words can afford.
For helpful comments on earlier versions of the manuscript, we are both grateful to George Marsden and two anonymous readers for Princeton University Press. In addition, James Turner thanks Jean Heffer, Francç;ois Weil, and Pap Ndiaye of the École des Hautes Études en Sciences Sociales and the members of the History Department Colloquium and of the Intellectual History Seminar of the University of Notre Dame for their kind criticism. He also appreciates the willingness of Professors Stephen Alter and Caroline Winterer to let him raid their well-stocked stores of ideas and information.
Jon Roberts thanks Christine Neidlein, Colleen Angel, and the other members of the staff at the University of Wisconsin–Stevens Point Interlibrary Loan Office for gracious, often heroic assistance. Members of the Department of History at the University of Wisconsin–Stevens Point gave him helpful feedback when he presented an abridged version of his contribution to this book at one of the Department's monthly brownbag lunch sessions. William B. Skelton provided a careful and intelligent reading of an earlier draft of this work. Ronald L. Numbers has read three versions and each time provided Roberts with his typically superb editorial and substantive advice. Daniel Thurs, a graduate student at the University of Wisconsin–Madison who is currently writing a dissertation on the history of the meaning of the term scientific method in the United States, graciously gave Roberts confidence that his own views on that subject were on target. His special appreciation, as always, to Sharon (ILYS) and Jeff. They continue to make it all worthwhile.
