536) ‘Halachic Fiction’ and ex post facto justification in the modern Halachic process

Introduction

This article—drawing extensively on the research of Professor Marc Shapiro examines the term ‘Halachic fiction.’ It is used to describe legal constructs in Halacha (Jewish law) that are not literally true, but serve as mechanisms to reconcile the demands of Halacha with the realities of lived experience. In other words, there is a category of Halacha—popular during the post Shulchan Aruch period (from the sixteenth century to this day)—where the “community’s ritual instinct” (Halbertal 2002:166, citing Jacob Katz), as well as custom, determine the law, sometimes to a greater extent than the rabbis.

535) Suspending Judaism between depth and accessibility: Maimonides and Yeshaya of Trani

Piskei haRid and Piskei haRiaz. Rid (grandfather) and Riaz (grandson) published together in one volume, although their worldviews were very different.

Introduction

This article—drawing extensively on the research of Professor Marc Shapiro[1]—asks whether the Italian commentator and Talmudist, R. Yeshaya di Trani (known as Riaz) had a larger influence on future Judaism than Maimonides. Riaz was one of the rabbis who vigorously opposed Maimonides during the Maimonidean Controversies that consumed the rabbinic world in the centuries after Maimonides’ passing in 1204. It seems that the rabbis were not ready for the radical expansiveness of Maimonidean thought, and under the leadership of Riaz—the great antiMaimonidean polemicist—refused to allow Judaism to be subjected to philosophical creed or inquiry. Maimonides’ towering philosophical system threatened to redefine Judaism as a religion of creed and rational inquiry. Not all rabbis were prepared to accept this radical shift, and Riaz emerged as one of the most forceful voices of resistance, rejecting the binding nature of Maimonides’ Thirteen Principles of Faith as well as his rationalism. Instead, he argued for a simpler, unsophisticated and non-dogmatic faith based solely on Halachic observance.

534) Between Law and Magic: The Mezuzah as a test case in shifting cosmologies


Introduction

This article—drawing extensively on the research of Professor Oded Yisraeli—examines references to the mezuzah from both before and after the emergence of the Zohar in the late thirteenth century, in order to trace shifting cosmologies. To map these changing approaches, we shall examine successive periods of Jewish literature from the third century to our times, each marked by distinct emphases and developments in the evolving mystical cosmology of the mezuzah.

533) The Seven Laws of Noah: Then and now

 

Jan Jansson's Duo Tituli Thalmudici Sanhedrin et Maccoth (Amsterdam, 1629)

Introduction

This articlebased extensively on the research by Yaacov Amar Rothsteinidentifies two distinct layers in the development of the Seven Laws of Noah, comprising an early rabbinic conception, and a later reinterpretation. In the Talmud and classical rabbinic sources, the Sheva Mitzvot Bnei Noach were not envisioned as a comprehensive universal religion for non‑Jews, but rather as a minimal legal frameworka baseline of obligations incumbent upon humanity with clear consequences for their violation. The difference between these two layers of perception is immense. The modern idea of a Noahide religion, presented as the original biblical faith intended for all non‑Jews, does not originate in rabbinic tradition. Surprisingly, it first emerged within Medieval Christian polemics and Early Modern[1] European thought. It was only as recently as about one hundred and fifty years ago that this universalist reading was taken up within Jewish discourse, most notably by R. Elia Benamozegh (d.1900), and later expanded upon by contemporary figures such as the Lubavitcher Rebbe and R. Adin Steinsaltz.
