This volume introduces what has sometimes been called "the third component of western culture". It traces the historical development of those religious traditions which have rejected a world view based on the primacy of pure rationality or doctrinal faith, emphasizing instead the importance of inner enlightenment or gnosis: a revelatory experience which was typically believed to entail an encounter with one's true self as well as with the ground of being, God.

The contributors to this book demonstrate this perspective as fundamental to a variety of interconnected traditions. In Antiquity, one finds the gnostics and hermetics; in the Middle Ages several Christian sects. The medieval Cathars can, to a certain extent, be considered part of the same tradition. Starting with the Italian humanist Renaissance, hermetic philosophy became of central importance to a new religious synthesis that can be referred to as Western Esotericism. The development of this tradition is described from Renaissance hermeticists and practitioners of spiritual alchemy to the emergence of Rosicrucianism and Christian theosophy in the seventeenth century, and from post-enlightenment aspects of Romanticism and occultism to the present-day New Age movement.

From rumors about gnostic orgies in antiquity to the explicit erotic symbolism of alchemical texts, from the subtly coded eroticism of medieval kabbalah to the sexual magic practiced by contemporary occultists and countercultural translations of Asian Tantra, the history of Western esotericism is rich in references to the domains of eros and sexuality. This volume, which brings together an impressive array of top-level specialists, is the first to analyze the eroticism of the esoteric without sensationalism or cheap generalizations, but on the basis of expert scholarship and attention to textual and historical detail. While there are few domains where the imagination may so easily run wild, the various contributions seek to distinguish fact from fiction-only to find that historical realities are sometimes even stranger than the fantasies. In doing so, they reveal the outlines of a largely unknown history spanning more than twenty centuries.

In Egypt during the first centuries CE, men and women would meet discreetly in their homes, in temple sanctuaries, or insolitary places to learn a powerful practice of spiritual liberation. They thought of themselves as followers of Hermes Trismegistus, the legendary master of ancient wisdom. While many of their writings are lost, those that survived have been interpreted primarily as philosophical treatises about theological topics. Wouter J. Hanegraaff challenges this dominant narrative by demonstrating that Hermetic literature was concerned with experiential practices intended for healing the soul from mental delusion. The Way of Hermes involved radical alterations of consciousness in which practitioners claimed to perceive the true nature of reality behind the hallucinatory veil of appearances. Hanegraaff explores how practitioners went through a training regime that involved luminous visions, exorcism, spiritual rebirth, cosmic consciousness, and union with the divine beauty of universal goodness and truth to attain the salvational knowledge known as gnosis.

Academics tend to look on 'esoteric', 'occult' or 'magical' beliefs with contempt, but are usually ignorant about the religious and philosophical traditions to which these terms refer, or their relevance to intellectual history. Wouter Hanegraaff tells the neglected story of how intellectuals since the Renaissance have tried to come to terms with a cluster of 'pagan' ideas from late antiquity that challenged the foundations of biblical religion and Greek rationality. Expelled from the academy on the basis of Protestant and Enlightenment polemics, these traditions have come to be perceived as the Other by which academics define their identity to the present day. Hanegraaff grounds his discussion in a meticulous study of primary and secondary sources, taking the reader on an exciting intellectual voyage from the fifteenth century to the present day and asking what implications the forgotten history of exclusion has for established textbook narratives of religion, philosophy and science.

Recent years have seen a spectacular rise of the New Age movement and an ever-increasing interest in its beliefs and manifestations.
This fascinating work presents the first-ever comprehensive analysis of New Age Religion and its historical backgrounds, thus providing the reader with a means of orientation in the bewildering variety of the movement.
Making extensive use of primary sources, the author thematically analyses New Age beliefs from the perspective of the study of religions. While looking at the historical backgrounds of the movement, he convincingly argues that its foundations were laid by so-called western esoteric traditions during the Renaissance. Hanegraaff finally shows how the modern New Age movement emerged from the increasing secularization of those esoteric traditions during the 19th century.
This ground-breaking publication is compulsive reading for all those involved or interested in the New Age movement.
