the manuscript through its final phases; Andrea Barnett, Laurel
Parker, Karenn Gobrecht, Cindi Vita Vogel, Ginny Ryan and
Christopher Ruser for their assistance; and the Cornell Library
system, including the rare books collection on mysticism and
superstition originally compiled by the University's first president,
Andrew Dickson White.
Parts of four of the chapters in this book were written with my
wife and long-time collaborator, Ann Druyan, who is also the
elected Secretary of the Federation of American Scientists - an
organization founded in 1945 by the original Manhattan Project
scientists to monitor the ethical use of science and high technology.
She has also provided enormously helpful guidance,
suggestions and criticism on content and style throughout the
book and at every stage of writing it over the course of nearly a
decade. I have learned from her more than I can say. I know how
lucky I am to find in the same person someone whose advice and
judgement, sense of humour and courageous vision I so much
admire, who is also the love of my life.
