It is a pleasure to acknowledge and thank those institutions and individuals who helped me with the production of this book. Some of my work was done while on a leave supported by a fellowship from the National Endowment for the Humanities. Additional support was provided by the Earhart Foundation, and by the College of Social Science, the Department of Political Science, and the Symposium on Science, Reason, and Modern Democracy, all at Michigan State University. The staffs of the Manuscripts Student Room and the North Library of the British Museum, where I did the work on the manuscript, the first edition, and the historiographic sources, were unfailingly helpful. The Interpretive Essay is a much revised version of a paper published in the Review of Politics (vol. 52, no. 4, Fall 1990). I thank the editors of that journal for permission to reprint the portions that are unchanged. My wife, Diane, with her usual toleration, put up with much neglect. This book is dedicated to the memory of my former student and friend, Jack Chapin, who died, much too young, from a voracious cancer. His death made me wish for a more advanced Baconian project. His courage in the face of death showed that some wonderful things could not be produced even by the complete conquest of nature.
