The editors thank Social Research for permission to reprint Leo Strauss’s “On the Intention of Rousseau,” which originally appeared in Social Research 14 (1947) 455–87 with an Erratum added in 15 (1948). We have made no other changes from the original published version. We also thank Presses Universitaires de France for permission to publish a translation of a portion of Terence Marshall’s book À la Recherche de l’Humanité (Paris: Presses Universitaires de France, 2009). We are grateful to Boston College for a publication grant that assisted with the acquisition of rights.

Eve Grace would like to thank the Social Science Executive Committee of Colorado College for its financial support. Both editors would also like to thank their assistants, Alec Arellano, Kimberley Stewart, and Allison D’Orazio, for their diligence and extensive work on the entire volume.
