Our journey into the history of the denomination ‘Jewish philosophy’ will include a leg that will lead us to certain declarations of political, moral, and scientific principles, and then on to the birth of what is called philosophia perennis or, in Christian circles, prisca theologia. Our subject of inquiry will thus be the birth of the concept of Jewish philosophy, Jewish theology and Jewish philosophy of religion.
A special emphasis will fall on the topic treated in the last part of this study: Jewish scepticism, a theme that involves a philosophical attitude founded on dialectical "enquiry", as the etymology of the Greek word skepsis properly means.
