The Hidden Masters of Pulp Fantasy

One of the regular series for which this blog was once known is Pulp Fantasy Library, in which I highlighted individual fantasy and science fiction stories I felt had been influential, directly or indirectly, on the development of the hobby of roleplaying. The series eventually grew to more than three hundred entries and taught me a great deal in the process of writing it. However, it also required considerable effort and often received little reader engagement, so I brought it to a quiet close in 2023. I sometimes consider reviving it in a modified form, but I’ve yet to find the right approach. Still, I keep thinking about these early works of fantasy, which is what led to this post.

From the vantage point of the first quarter (!) of the twenty-first century, it’s all too easy to forget just how strange fantasy and science fiction once were – not merely in their imaginative content but in the intellectual and spiritual traditions from which they drew. We tend to think of early speculative fiction as arising primarily from a matrix of adventure tales, scientific romances, and classical mythology. However, another powerful and often overlooked influence is the world of Spiritualism, Theosophy, and other esoteric traditions. These weren’t mere fads in the late 19th and early 20th centuries; they were serious systems of belief for many, including a surprising number of the authors who helped lay the foundations of what we now call genre fiction.

Even more fascinating is how many once-occult concepts have since become commonplaces of fantasy and science fiction, like astral projection, past lives, lost advanced civilizations, invisible planes of existence, and cosmic cycles of spiritual evolution, to name just a few obvious ones. These weren’t originally the products of scientific or rationalist speculation. They were occult doctrines, often articulated with the structure and certainty of any other religion. Early speculative fiction served as a powerful conduit for these ideas, transmitting them into the cultural imagination.

Take, for instance, astral projection, which recurs throughout pulp fantasy and science fiction. In Theosophy, this is the “etheric body” or “etheric double” leaving the physical body to traverse the astral plane. In fiction, this idea becomes John Carter’s unexplained voyage to Barsoom in A Princess of Mars, where his body remains behind on Earth while his spirit is transported to another world by sheer force of will. Burroughs never offers a scientific explanation for the phenomenon nor did he need to do so. His readers would likely have recognized the trope from already extant popular occult literature.

Similarly, reincarnation and karma, central tenets of Theosophy and many forms of Eastern-influenced Spiritualism, appear in the works of authors like Talbot Mundy, whose protagonists sometimes recall past lives in ancient empires. The same is true of many tales penned by Abraham Merritt. In The Star Rover, Jack London tells the story of a prisoner who escapes his unjust physical confinement by entering trance states that allow him to access a series of former incarnations. This isn’t merely a fictional conceit; it reflects a specific metaphysical worldview in which human identity unfolds across many lifetimes, a view that gained traction during the late 19th and early 20th centuries. Even readers who didn’t share this worldview would nevertheless have been familiar with it.

William Hope Hodgson is another fascinating case. He blends arcane science with mystical speculation in his "Carnacki the Ghost-Finder" stories, which feature protective sigils, vibrational zones, and references to the "Outer Circle," a realm inhabited by malevolent entities existing just beyond human perception. All of these ideas draw heavily on contemporary occultism. His novel The Night Land, a work of science fantasy more than horror, is set on a dying Earth haunted by monstrous spiritual forces and saturated with the oppressive weight of cosmic time. It echoes Theosophical doctrines of vast evolutionary cycles and the occult preoccupation with psychic resistance to spiritual evil.

Marie Corelli (born Mary Mackay), once one of the most popular authors in the English-speaking world, is now rarely read. Her novel, A Romance of Two Worlds, for example, blends Spiritualist belief with melodrama and science fictional concepts, such as portraying electricity as a bridge between the material and spiritual realms. She directly influenced writers like H. Rider Haggard and even Arthur Machen, both of whom in turn shaped the subsequent development of fantasy. Even Edward Bulwer-Lytton, now best known for the infamous incipit “It was a dark and stormy night,” was a serious student of esoteric lore. His novel Zanoni depicts an immortal Chaldean adept who achieves transcendence through secret knowledge, an early example of the “hidden masters” who would later become a staple of Theosophy.

Which, of course, brings us to Theosophy itself, which had perhaps the most lasting and far-reaching impact on the development of both esoteric thought and fantasy. Founded in the 1870s by the Russian-born mystic, Helena Blavatsky, Theosophy combined elements of Hinduism, Buddhism, Neoplatonism, and esoteric Christianity into a vast occult cosmology. Through books, journals, and lectures, it promoted a view of the universe in which mankind was but one phase in an immense spiritual drama, involving lost continents, ascended masters, and ancient wisdom. These ideas found fertile ground in genre fiction. The controversial “Shaver Mystery” stories published in Amazing Stories in the mid to late 1940s and purportedly based on true events involve ancient subterranean races like the evil Deros (which itself served as an inspiration to Gary Gygax). Shaver's stories read like Theosophy blended with pulp sensationalism.

Even Clark Ashton Smith, whom regular readers will know is my favorite of the Weird Tales trio, drew on esoteric themes. Ideas like cyclical time, forgotten civilizations, and arcane knowledge recur throughout his work. His Zothique cycle, set on the last continent of a dying Earth, reflects the Theosophical notion of a future “seventh root race” and the eventual exhaustion of history.

Against this background, H.P. Lovecraft stands out, not because he rejected religion in general (though he did), but because he specifically targeted Spiritualism and occultism. He was deeply familiar with the claims of mediums, astrologers, and Theosophists and dismissed them with open contempt. In his correspondence, he regularly mocks the “credulous” who place faith in séances, reincarnation, and similar beliefs. At the behest of Harry Houdini, Lovecraft even collaborated on a book titled The Cancer of Superstition, intended as a wholesale debunking of Spiritualist claims. The book was never completed due to Houdini’s sudden death in 1926.

Despite this, Lovecraft’s stories are filled with forbidden books, lost knowledge, and ancient alien races whose truths are too terrible for the human mind to bear. In this way, Lovecraft doesn’t discard the tropes of occult literature – he inverts them. Where Theosophy promised spiritual enlightenment and cosmic unity, Lovecraft offers only madness, degeneration, and a universe that is not merely indifferent but actively hostile to notions of human significance. His “gods” are not hidden masters but incomprehensible and uncaring forces. Structurally, however, he preserves much of the occult worldview: a hidden reality lurks behind the surface of things, accessible only to initiates – scholars, madmen, and cultists. Lovecraft didn’t reject that structure; he twisted it and filled it with dread.

All of this makes it remarkable just how thoroughly modern fantasy and science fiction still bear the imprint of these early occult influences. Astral travel, alternate planes, soul transference, hidden masters, and cosmic cycles remain staples of the genres. They’re treated today as neutral, even secular, tropes of worldbuilding, even though their origins are anything but secular. They are spiritual, mystical, and often explicitly religious in intent.

My purpose in this post isn't to diminish these genres or to reduce their works to a list of influences. Nor am I offering an invitation to embrace the esoteric as literal truth. Instead, I'm reminding everyone of just how permeable the boundary between belief and imagination has always been and how fantasy, in particular, has long served as a vessel for metaphysical speculation, even when dressed in the garb of swords and sorcery or rocket ships and ray guns. Perhaps this is one of the reasons these genres endure: they don’t merely entertain; they echo the ancient human desire to find meaning in a world that so often seems devoid of it.
