Book excerpt: The Spiritual Fallacy, though packed with arcane facts, is unique in revealing how one the greatest metaphysicians of our age interprets the phenomena, real or alleged, of spiritualism. The doctrinal expositions that accompany his astonishing account offer extraordinarily prescient insight into many deviations and psychological afflictions of the modern mind, and will be a valuable to psychological practitioners and spiritual counselors as to historians of esoteric history. It also offers a profound corrective to the many brands of New Age 'therapy' that all too unwittingly invoke many of the same elements whose nefarious origins Guenon so clearly described many years ago.
