In this lucid explanation of perennial philosophy, Arthur Versluis reveals this tradition-so often described as esoteric and inaccessible-to be closer to our interests and experience than many of us have realized. Versluis has distilled an immense amount of scholarship into this small volume, but its brevity is deceiving. Like the culmination to any alchemical work, _Perennial Philosophy_ is a powerful tincture that-once imbibed-transports receptive readers to a world in which they are part of a spiritual hierarchy that links heaven to earth. Arthur Versluis has distilled an immense amount of scholarship to produce a disarmingly accessible, lucid, and deeply penetrating study of the great philosophic traditions that underlie Western culture. Versluis concisely explains what perennial philosophy is and what it isn't. The clarity of his prose makes this deep book a pleasure to read. A remarkable achievement! -Gregory Shaw, author of _Theurgy and the Soul: The Neoplatonism of Iamblichus_
