A biography of Isaac Orobio de Castro, a crypto-Jew from Portugal and one of the most prominent intellectual figures in the 17th century. This work sheds light on the life of a Jewish community of former Christians in Amsterdam and examines their dilemmas and attempts to create a new identity.

The series Studies and Texts in Scepticism contains monographs, translations, and collected essays exploring scepticism in its dual manifestation as a purely philosophical tradition and as a set of sceptical strategies, concepts, and attitudes in the cultural field - especially in religions, perhaps most notably in Judaism. In such cultural contexts scepticism manifests as a critical attitude towards different dimensions and systems of secular or revealed knowledge and towards religious and political authorities. It is not merely an intellectual or theoretical worldview, but a critical form of life that expresses itself in such diverse phenomena as religion, literature, and society. Further book series of the Maimonides Centre for Advanced Studies are Jewish Thought, Philosophy, and Religion and the Yearbook of the Maimonides Centre for Advances Studies.

The essays in this volume deal with the social and intellectual history of the Western Spanish and Portuguese Jews who established new communities in Northwestern Europe during the seventeenth century. The founders of these communities were mainly former Marranos, descendants of those Jews who had converted to Christianity in the closing years of the Middle Ages. After being separated from the Jewish world for many generations, they returned to Judaism and became an integral part of the Sephardi nation. Amsterdam became the metropolis of this new Jewish diaspora, which was characterised by both its involvement in colonial trade and its intellectual ferment. The reencounter of these Jews with Judaism was a complex affair, and for many of these former New Christians rabbinic Judaism aroused harsh criticism. In order to set the boundaries of their new identity, the leadership of the Sephardi communities of Amsterdam, Hamburg and London adopted a variety of strategies designed to rein in these wayward spirits. This process of socialisation into the Jewish world created a new type of Judaism, and those whose Jewish life was framed by this new amalgam can be considered the precursors of modernity in European Jewish society.

The essays in this book depict the social and intellectual ferment of the former "Marranos" from Spain and Portugal who returned to the fold of Judaism in Western Europe during the seventeenth century and established new Jewish communities in Amsterdam, Hamburg and London.
