Conference: The “Excluded Third” in the Co-Production of Judaism, Christianity, and Islam
Organized by Mercedes García-Arenal, Katharina Heyden, David Nirenberg, and Davide Scotto
Judaism, Christianity, and Islam are often understood as an ensemble of three (‘Abrahamic,’ ‘monotheistic,’ scriptural, or prophetic) religious communities and traditions. But often when adherents of two of these “sibling” religions interact, the third is treated as a figure to be marginalized, stigmatized, or instrumentally exploited vis-à-vis the others. This conference proposes to explore this dynamic of the excluded third.
