Abstract

In this book, Joseph Citron offers the first comprehensive analysis of Prague Rabbi Isaiah Horowitz's (1565-1629) magnum opus of Jewish ethical literature, the Shnei Luhot Ha-Berit. Citron's close philological analysis reveals the pioneering nature of the work in creating an organic Jewish theological system rooted in the mystical structures of Kabbalah, cultivating an orthodoxy in thought and legal practice based upon its principles. Emotion, psychology, self-actualisation and joy are all presented as essential facets of religious life, significantly influencing the 17th-century Sabbatean movement, the 18th-century Hasidic movement, and the Orthodox movement of the 19th century. The book is essential for scholars and laypeople alike wishing to understand the evolution of European Judaism in the early modern period.
