As part of Professor’s Claude Stuczyniski’s research project on Conversos and ex-Converso 'New Jews' perceived as agents, victims and thinkers of Early Modern Imperialism at the Jean & Samuel Frankel Center for Judaic Studies, he will revisit Isaac Cardoso's major apologetic treatise "Las Excelencias de los hebreos" (Amsterdam, 1679). After surveying the ambivalent attitudes of other ex-Converso Jews living in the Sephardic diaspora in front of Iberian Early Modern imperialism, he will stress the radicality of Cardoso's criticism against political dominion, especially contemporary empires, even rejecting the self-critical caveats endorsed by the School of Salamanca. Cardoso's staunch anti-imperialism will be explained on grounds of his apologetical and counter-cultural theological-political views of Judaism. At the same time, Professor Stuczynski will show that these views could easily undermine Cardoso's own efforts to depict the Jews as the most faithful and useful political subjects. He will ask, whether Cardoso was aware of this immanent political contradiction? An answer to this question will enable look at Cardoso's case as a liminal barometer to check what pre-Emancipation Jews could and could not argue regarding contemporary empires.
