In describing the career of Abraham Yagel, a Jewish physician, kabbalist, and naturalist who lived in northern Italy from 1553 to about 1623, David Ruderman observes the remarkable interplay between early modern scientific thought and religious and occult traditions from a wholly new perspective: that of Jewish intellectual life.

Whether he was writing about astronomical discoveries, demons, marvelous creatures and prodigies of nature, the uses of magic, or reincarnation, Yagel made a consistent effort to integrate empirical study of nature with kabbalistic and rabbinic learning. Yagel's several interests were united in his belief in the interconnectedness of all thing—a belief, shared by many Renaissance thinkers, that turns natural phenomena into “signatures” of the divine unity of all things. Ruderman argues that Yagel and his coreligionists were predisposed to this prevalent view because of occult strains in traditional Jewish thought He also suggests that underlying Yagel's passion for integrating and correlating all knowledge was a powerful psychological need to gain cultural respect and acceptance for himself and for his entire community, especially in a period of increased anti-Semitic agitation in Italy.

Yagel proposed a bold new agenda for Jewish culture that underscored the religious value of the study of nature, reformulated kabbalist traditions in the language of scientific discourse so as to promote them as the highest form of human knowledge, and advocated the legitimate role of the magical arts as the ultimate expression of human creativity in Judaism. This portrait of Yagel and his intellectual world will well serve all students of late Renaissance and early modern Europe.

Here is a major contribution to the history of Christian kabbalism by an eminent authority. Giovanni Pico della Mirandola, a central figure in Lorenzo de' Medici's Platonic Academy, was the first notable Christian humanist to become learned in the Kabbalah; and the two sets of kabbalistic theses he wrote started Kabbalah on its Christian career. This is a study of those theses, their meaning, and their relation to the Hebrew texts Pico studied.

Chaim Wirszubski establishes which Hebrew texts Pico used and identifies the sources for individual theses. In the process he provides special insight into Jewish Kabbalah and its several schools. Pico's goal was to use Jewish Kabbalah to confirm Christian theology. In his analysis of Conclusiones Cabalisticae, Wirszubski elucidates this Christian kabbalistic doctrine and shows how it was tied to other currents in Renaissance thought, especially platonism and magic. This study will be valued by students of mysticism and of Renaissance thought.

Bringing to light a hidden chapter in the history of modern Judaism, Shamanic Trance in Modern Kabbalah explores the shamanic dimensions of Jewish mysticism. Jonathan Garb integrates methods and models from the social sciences, comparative religion, and Jewish studies to offer a fresh view of the early modern kabbalists and their social and psychological contexts.

Through close readings of numerous texts—some translated here for the first time—Garb draws a more complete picture of the kabbalists than previous depictions, revealing them to be as concerned with deeper states of consciousness as they were with study and ritual. Garb discovers that they developed physical and mental methods to induce trance states, visions of heavenly mountains, and transformations into animals or bodies of light. To gain a deeper understanding of the kabbalists’ shamanic practices, Garb compares their experiences with those of mystics from other traditions as well as with those recorded by psychologists such as Milton Erickson and Carl Jung. Finally, Garb examines the kabbalists’ relations with the wider Jewish community, uncovering the role of kabbalistic shamanism in the renewal of Jewish tradition as it contended with modernity.
