Tannery and Duhem on the Concept of a System in the History of Philosophy and History of Science

ABSTRACT

This article examines John Toland’s Reasons for Naturalizing the Jews (1714) by placing it alongside other elements of his engagement with Jewish history, Mosaic principles and wider “Hebraica” – specifically, an appendix to his Nazarenus (1718) and his Origines Judaicae (1709). Although Toland’s case for Jewish naturalization shows the strong influence of Locke’s case for political and religious toleration, and also of a general “mercantilism”, it is argued that one of its main characteristics is a philosophical naturalism, shown in its treatment of the human species as a whole. Furthermore, it is also argued that this same naturalism is evident throughout Toland’s engagement with Jewish history and Mosaic thought. Accordingly, when we “fold” these works into each other, we find each enhancing our understanding of the others – not just as examples of Toland’s treatment of “Jewish affairs”, but also as illustrations of a consistent conceptual materialism. To emphasize this, the article concludes by suggesting that the figure of Rabbi Simone Luzzatto, author of a 1638 plea for tolerance, provides an important clue in understanding the links between Toland’s political injunctions and the philosophical foundation on which they are built.
