The more than 30 essays in this volume examine the engagement of the Enlightenment with esoteric traditions of the Early Modern Era and the transformative pathways by which Hermeticism, magic, alchemy, and Kabbalah influenced Spiritualism, Occultism, and Theosophy. The contributors explore intersections between the Enlightenment and Esotericism and identify the concerns and preoccupations that made possible the transition to modern esotericism.
