"This collection presents in a clear and concise way a series of critical distinctions that collectively map the field: Hermetism, Gnosticism, gnosis, Manichaeism, Hermeticism, Catharism, Esotericism, Romanticism, and the New Age. These often confused and misperceived phenomena have been delineated crisply, in a way that permits this collection to serve nicely as a general introduction to the field. This book articulates a new standard of precision and clarity." -- Dan Merkur, author of Gnosis: An Esoteric Tradition of Mystical Visions and Unions<br /><br />"This work meets the current demand for scholarly, empirico-historical research in what the editors rightly denominate the 'third current' (the others are biblical faith and Greek rationality) of Occidental thought, i.e., Western Esotericism."-- Ralph Slotten, Dickinson College
