Neil Mann works as an editor, translator, and teacher, and as an independent scholar, specializing in the works of W. B. Yeats, particularly his esoteric interests and A Vision. He is one of the readers who is simultaneously frustrated and fascinated by A Vision and the system that W. B. Yeats and his wife, George, elaborated through years of occult experiment and personal research. In 2002, he created the website YeatsVision.com as a resource for those seeking to understand this work better, and this book is the result of some forty years of engagement with A Vision, Yeats's work as a whole, and the background of nineteenth-century spirituality.
