Simone de Beauvoir’s Philosophical Writings is dedicated to Kate Fullbrook, whose discoveries with Edward Fullbrook inspired the Beauvoir Series project. This volume would not have been possible without the generous support of a Collaborative Research Grant from the National Endowment for the Humanities (NEH), an independent federal agency; a Matching Funds grant from the Illinois Board of Higher Education allocated by the Graduate School of Southern Illinois University Edwardsville (SIUE); and a translation grant from the French Ministry of Culture. I am very grateful to the following persons for their encouragement and assistance: Margot Backas and Michael Hall, of NEH; Anne Solange Noble and Florence Giry, of Éditions Gallimard; Joan Catapano, editor in chief of the University of Illinois Press; and Dean Steve Hansen, Provost Sharon Hahs, Dean Kent Neely, David Steinberg, Tom Paxson, and Bill Hamrick, all of SIUE. This volume and the Beauvoir Series project as a whole have benefited from the guidance of the members of the Beauvoir Series Editorial Board: Kristana Arp, Debra Bergoffen, Anne Deing Cordero, Elizabeth Fallaize, and Eleanore Holveck. For their assistance in identifying quotations, I thank Bill Hamrick, Carol Keene, Henry W. Pickford, Matthew Schmitz, Carl Springer, Julie Ward, and Edwin Lawrence. The many transcribers, translators, and authors of introductions, listed with the individual texts, have taught me so much about Beauvoir’s philosophy, and I am grateful to them. I would like to give special thanks to Jo Barnes and Janette Johnson for their assistance with administering the grants; Bessie Richards and Hope Myers for tracking down Beauvoir’s elusive texts; Marybeth Timmermann and Mary Beth Mader for their help in editing the translations; and my coeditor of the Beauvoir Series, Sylvie Le Bon de Beauvoir, for her warm encouragement and steadfast support.
