KNOWLEDGE: Do we obtain reliable knowledge about the world from ongoing supernatural revelation, or from scientific investigation? NATURE: Is it preferable to perceive God as working through nature, or through supernatural miracles? SUPERNATURAL ENTITIES: Are we surrounded by all kinds of supernatural forces and entities, such as endless conscious angels, demons and the Evil Eye? MITZVOT: Do the commandments function solely to change our thoughts and behavior, or primarily to manipulate mystical forces? TORAH: Is Torah a Divine guide for life, or is it also a metaphysical blueprint for existence with all kinds of supernatural qualities? Rationalism vs. Mysticism is a thorough study of how these questions were answered very differently by various rabbinic scholars over history, reflecting two fundamentally different views of the nature of Judaism. It will profoundly deepen your understanding of Judaism and many of the intellectual conflicts that have arisen in Jewish history.

A rapidly expanding Islamic revival movement shows that Islamic rationalism and not jihadism is to define twenty-first century Islam.

Table of contents

The forgotten legacy of religious Jewish anarchism, and the adventures and ideas of its key figures, finally comes to light in this book. Set in the decades surrounding both world wars, No masters but God identifies a loosely connected group of rabbis and traditionalist thinkers who explicitly appealed to anarchist ideas in articulating the meaning of the Torah, traditional practice, Jewish life and the mission of modern Jewry. Full of archival discoveries and first translations from Yiddish and Hebrew, it explores anarcho-Judaism in its variety through the works of Yaakov Meir Zalkind, Yitshak Nahman Steinberg, Yehudah Leyb Don-Yahiya, Avraham Yehudah Heyn, Natan Hofshi, Shmuel Alexandrov, Yehudah Ashlag and Aaron Shmuel Tamaret. With this ground-breaking account, Hayyim Rothman traces a complicated story about the modern entanglement of religion and anarchism, pacifism and Zionism, prophetic anti-authoritarianism and mystical antinomianism.

Maimonides’ vision of Judaism was deeply elitist, but at the same time profoundly universalistic. He was highly critical of the regnant Jewish culture of his day, which he perceived as so heavily influenced by ancient Jewish mysticism as to be debased. While focusing on that critique, Menachem Kellner skilfully and accessibly demonstrates how Maimonides used philosophy to purify a corrupted and paganized religion, and to present distinctions fundamental to Judaism as institutional, sociological, and historical, rather than ontological. In Maimonides’ hands, metaphysical distinctions are translated into moral challenges.

An original study of the transformation of Safavid Persia from a majority Sunni country to a Twelver Shi'i realm "Mysticism" in Iran is an in-depth analysis of significant transformations in the religious landscape of Safavid Iran that led to the marginalization of Sufism and the eventual emergence of 'irfan as an alternative Shi'i model of spirituality. Ata Anzali draws on a treasure-trove of manuscripts from Iranian archives to offer an original study of the transformation of Safavid Persia from a majority Sunni country to a Twelver Shi'i realm. The work straddles social and intellectual history, beginning with an examination of late Safavid social and religious contexts in which Twelver religious scholars launched a successful campaign against Sufism with the tacit approval of the court. This led to the social, political, and economic marginalization of Sufism, which was stigmatized as an illegitimate mode of piety rooted in a Sunni past. Anzali directs the reader's attention to creative and successful attempts by other members of the ulama to incorporate the Sufi tradition into the new Twelver milieu. He argues that the category of 'irfan, or "mysticism," was invented at the end of the Safavid period by mystically minded scholars such as Shah Muhammad Darabi and Qutb al-Din Nayrizi in reference to this domesticated form of Sufism. Key aspects of Sufi thought and practice were revisited in the new environment, which Anzali demonstrates by examining the evolving role of the spiritual master. This traditional Sufi function was reimagined by Shi'i intellectuals to incorporate the guidance of the infallible imams and their deputies, the ulama. Anzali goes on to address the institutionalization of 'irfan in Shi'i madrasas and the role played by prominent religious scholars of the eighteenth and early nineteenth centuries in this regard. The book closes with a chapter devoted to fascinating changes in the thought and practice of 'irfan in the twentieth century during the transformative processes of modernity. Focusing on the little-studied figure of Kayvan Qazvini and his writings, Anzali explains how 'irfan was embraced as a rational, science-friendly, nonsectarian, and anticlerical concept by secular Iranian intellectuals.

In 1913, Russian imperial marines stormed an Orthodox monastery at Mt. Athos, Greece, to haul off monks engaged in a dangerously heretical practice known as Name Worshipping. Exiled to remote Russian outposts, the monks and their mystical movement went underground. Ultimately, they came across Russian intellectuals who embraced Name Worshipping—and who would achieve one of the biggest mathematical breakthroughs of the twentieth century, going beyond recent French achievements. Loren Graham and Jean-Michel Kantor take us on an exciting mathematical mystery tour as they unravel a bizarre tale of political struggles, psychological crises, sexual complexities, and ethical dilemmas. At the core of this book is the contest between French and Russian mathematicians who sought new answers to one of the oldest puzzles in math: the nature of infinity. The French school chased rationalist solutions. The Russian mathematicians, notably Dmitri Egorov and Nikolai Luzin—who founded the famous Moscow School of Mathematics—were inspired by mystical insights attained during Name Worshipping. Their religious practice appears to have opened to them visions into the infinite—and led to the founding of descriptive set theory. The men and women of the leading French and Russian mathematical schools are central characters in this absorbing tale that could not be told until now. Naming Infinity is a poignant human interest story that raises provocative questions about science and religion, intuition and creativity.
