ACKNOWLEDGMENTS

While working on the original French edition of this study, I published several sections in the English language. These pieces not only suffered from being taken out of their systematic context, but all of them were also preliminary versions, later reworked. Nevertheless I wish to thank the directors of the following publishing houses and journals for their permission to resettle in its native habitat material first printed in diaspora: The Columbia University Press, Human Studies, Man and World, Precedent Publishing, Social Research, and The State University of New York Press.
