545) Psychedelics: Cutting-edge science or shamanic ritual?

Homological scaffolds of the brain before and after psilocybin (Petri G., et al. 2014).

Introduction

This article builds on the previous discussion, which explored how psychedelics are increasingly being framed as “cutting-edge science,” embraced by “all the professors”—and, most troubling in my view, promoted as a new expression of Jewish mysticism and experientialism [Kotzk Blog: 544) Acculturating Alcohol and Sanctifying Psychedelics: It’s time to stand up]. While this article departs from the usual style of discourse on this platform, a recent encounter prompted me to dig deeper. After hearing an average, conservative, middle-aged man explain that he was about to embark on an ayahuasca journey because of its “proven scientific value” and its common use among “trusted religious people” in his community, I decided to examine the academic literature on psychedelics more closely. I aimed to assess how solid the claim of a scientific foundation truly is. In the interest of fairness, I have included scholarly arguments both for and against the use of psychedelics.

544) Acculturating Alcohol and Sanctifying Psychedelics: It’s time to stand up


Introduction

Alcohol and drug abuse have long been perceived as problems external to the Jewish religious community. Currently, however, the rising visibility of alcohol consumption alongside drug and psychedelic practices, is closer to home than we may have imagined. According to psychologist Dan Wolf,[1] the difficulty lies in the fact that, whereas in the past, a range of methodologies were actively employed to counter alcohol and substance abuse, the prevailing attitude seems to be that quiet and moderate use is perhaps the most reasonable approach. Today, the issue of substances and psychedelics is no longer abstract or distant; it is reshaping the very fabric of our communal life, demanding recognition, response and a solid stance.

543) Where are the first Chassidic texts?


Zemir Aritzim, published in 1772: Under the directive of the first Rebbe of Chabad, all existing copies of Zemir Aritzim were gathered and burned, leaving only two surviving copies. 

Introduction

This article—drawing extensively on the groundbreaking research of Dr Elly Moseson[1]examines the obscure world of early Chassidic manuscripts that circulated well before the first printed, and official Chassidic book, Toledot Yaakov Yosef, in 1780. We explore the nature of the earliest Chassidic handwritten manuscripts, produced in the two decades between the passing of the Baal Shem Tov in 1760 and the publication of the first printed Chassidic book in 1780, before Chassidism became institutionalised.

542) Zoharic Kabbalah as mystical resistance to Christianity


 Introduction

This article—drawing extensively on the research of Professor Hartley Lachter[1]examines how Medieval Kabbalists constructed a theology of resistance in response to negative Christian portrayals of (particularly) the male Jewish body, as flawed, inferior and weak. In response, the Kabbalists advanced a counter-narrative that framed Jewish bodies as sacred, resilient and transcendent of time. This Kabbalistic interpretation also allowed Jews to see themselves as instrumental in a redemptive history, turning accusations of faithlessness by rejecting Jesus into affirmations of faithfulness to divine mystery. They were no longer inferior, but through Kabbalah—indeed superior.

541) Romancing the Manuscript: The politics of knowledge in Chatam Sofer’s rejection of print.

Manuscript fragment of Toledot Yeshu
Introduction

This article—drawing extensively on the research of Professor Maoz Kahana[1]—examines R. Moshe Schreiber (known as Chatam Sofer, 1762-1839) and his ambivalent stance toward the well-established print culture of Jewish books, which had flourished since its beginnings three centuries earlier in 1475. In place of embracing print as the dominant medium, he issued a striking call for a return to manuscripts. Chatam Sofer is a major rabbinic figure who “carries the aura of a founding figure in the sociological fabric of modern Judaism” (Kahana 2025:300). 

By privileging manuscripts, Chatam Sofer reinforced rabbinic control over textual transmission, resisting the democratisation of knowledge that print enabled. As opposed to mechanical printing, manuscripts circulated in smaller, more controlled circles, limiting exposure to the unorthodox ideas that sometimes sprouted from the Enlightenment movement (Haskalah), whichsignificantlyused print aggressively to promote its agenda.

540) Theo-politics of early rabbinic printing and the race for first publication


Levush haOrah by R. Mordechai Jaffe first published in 1603

Introduction

This articledrawing extensively on the research of Professor Eric Laweeexamines the publication of rabbinic texts during the Late Medieval and Early Modern Periods,[1] in the aftermath of the invention of the printing press around 1450. It focuses on the printing struggles of R. Mordechai Jaffe (c.1530–1612)—also known as the Levush, or Baal haLevushim—and especially on the personal reflections contained in the epilogue to his Levush haOra. 

The first Hebrew books were printed in Rome around 1470. Rabbinic books (sefarim) were not always selfless, intellectual and spiritual contributions for the edification of the People of Israel. The reality of rabbinic publishing was far more complicated. Publishing was not just about scholarship, but also about authority, the tension between tradition and innovation, and the practical challenges of getting a manuscript into print. It was about survival in a crowded marketplace of ideas, where every published gloss and commentary bore the promise of Chashivutlegitimacy, influence, power and authorityfor its author. But behind the finished published product sometimes lay a hidden world of rivalry, negotiation, polemics and politics.

539) The new Rebbe of Thieves

Resisei Laila given to me by R. Shlomo Carlebach

Introduction

I recently experienced a brief lapse back into my earlier self, when I was totally captivated by the romance of Chassidism, which included a diversion into the magnetism of R. Shlomo Carlebach, his music and teachings. I once asked R. Shlomo what I needed to do to become his Chassid. He smiled and said (typically), “But I want to be a Chassid of you!” I replied, “No, seriously...” He then told me to go to the Mikveh just before Shabbos and to read Resisei Leilah by R. Zadok haCohen. I went to the Mikveh, but I could never find a copy of Resisei Leilah. Years later, someone unexpectedly gave me a small parcel wrapped in brown paper. When I opened it, it was the well-used personal copy of Resisei Leilah that R. Shlomo carried around with him. Apparently, he met someone at the airport, heard they were going to South Africa and gave them his book to give to me. I was overwhelmed and felt like I was living in one of the Chassidic stories he used to tell. Years have passed, times have changed, and my interests and pursuits have moved on, but that little worn blue book remains one of my prized possessions.

538) Rules for writing a Sefer Torah: Rabbinic innovation or reflection of an existing scribal tradition?

Introduction

This article—drawing extensively on the research of Professor Emanuel Tov, former Editor-in-Chief of the Dead Sea Scrolls Publication Project[1]—examines the rabbinic rules for writing a Sefer Torah. These laws are among the most detailed and revered in rabbinic literature. Every letter, margin, and column is prescribed with precision, creating the impression of a system wholly devised by the rabbis to safeguard the sanctity of the text. Yet the discovery of the Dead Sea Scrolls has complicated this picture. As Emanuel Tov has shown, many of these rabbinic instructions echo standard and common practices already in use among scribes in the Judean Desert centuries earlier. Thus, what previously may have seemed like a unique rabbinic innovation in scribal law now appears, at least in part, to be the codification of an existing scribal traditionif not a form of acculturation.[2]

537) When Did We All Start Ignoring the "Sealing of the Talmud"?


This post, by Boruch Clinton, originally appeared on the B'chol D'rachecha site.

It’s popularly understood that the completion of the Talmud around 1,500 years ago marked a critical transition in halachic history. From that point on, halachic conclusions found in the Talmud were binding on all Jews everywhere and for all time.

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.
