The articles collected in this Spring 2009 (VII, 2) issue of Human Architecture: Journal of the Sociology of Self-Knowledge entitled "Historicizing Anti-Semitism" were part of an international conference entitled, "The Post-September 11 New Ethnic/Racial Configurations in Europe and the United States: The Case of Anti-Semitism," organized by Lewis Gordon and Ramón Grosfoguel at the Maison des Sciences de l'Homme (MSH) in Paris on June 29-30, 2007. Part of a series inaugurated by a discussion on Islamophobia, they brought a majority Jewish group of scholars together in the hope of bringing to the forum a critical exchange and conversation among the participants. The articles gathered here do not represent a unified voice but those often unheard in discussions of anti-Semitism. The focus on anti-Semitism in this collection raises the question of how ancient and Medieval versions of anti-Jewish practices should be interpreted, especially since even the term "Semite" came about as an effort in eighteenth-century French and German scholarship to organize Arabic, Aramaic, and Hebrew under a single linguistic nomenclature, which was crystallized in the nineteenth century in the work of the French scholar Ernest Renan. Contributors include: Lewis R. Gordon (also as journal issue guest editor), Ramón Grosfoguel (also as journal issue guest editor), Eric Mielants (also as journal issue guest editor), David Ost, James Cohen, Santiago E. Slabodsky, Rabson Wuriga, Walter Mignolo, Ramón Grosfoguel, Marc H. Ellis, Etienne Balibar, Ivan Davidson Kalmar, Martine Chard-Hutchinson, Michael Löwy, Jean-Paul Rocchi and Mohammad H. Tamdgidi (also as journal editor-in-chief).
