Few religious currents have been as influential as the Theosophical. Yet few currents have been so under-researched, and the Brill Handbook of the Theosophical Current thus represents pioneering research. A first section surveys the main people and events involved in the Theosophical Society from its inception to today, and outlines the Theosophical worldview. A second, substantial section covers most significant religions to emerge in the wake of the Theosophical Society - Anthroposophy, the Point Loma community, the I AM religious activity, the Summit Lighthouse Movement, the New Age, theosophical UFO religions, and numerous others. Finally, the interaction of the Theosophical current with contemporary culture - including gender relations, art, popular fiction, historiography, and science - are discussed at length.
