Ren Gu non (1886-1951) is undoubtedly one of the luminaries of the twentieth century, whose critique of the modern world has stood fast against the shifting sands of recent philosophies. His oeuvre of 26 volumes is providential for the modern seeker: pointing ceaselessly to the perennial wisdom found in past cultures ranging from the Shamanistic to the Indian and Chinese, the Hellenic and Judaic, the Christian and Islamic, and including also Alchemy, Hermeticism, and other esoteric currents, at the same time it directs the reader to the deepest level of religious praxis, emphasizing the need for affiliation with a revealed tradition even while acknowledging the final identity of all spiritual paths as they approach the summit of spiritual realization. Many readers of Gu non's doctrinal works have hoped for translations of his detailed expos s of Theosophy and Spiritism. Sophia Perennis is pleased now to make available both these important titles as part of the Collected Works of Ren Gu non. Whereas Theosophy: History of a Pseudo-Religion centers primarily on historical details, The Spiritist Fallacy, though also packed with arcane facts, is unique in revealing how one of the greatest metaphysicians of our age interprets the phenomena, real or alleged, of Spiritism. The doctrinal expositions that accompany his astonishing account of Spiritism offer extraordinarily prescient insight into many deviations and 'psychological' afflictions of the modern mind, and should be as valuable to psychiatrists and spiritual counselors as to historians of esoteric history. And 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 Gu non so clearly pointed out many years ago.
