From small shamanic communities to modern prohibition, access to entheogens has been progressively restricted as civilizations expanded—and their rediscovery in the West appears far from accidental.
This lecture was delivered at the II Conference for the Study of Altered States of Mind, held in Lleida, Spain, in October 1994.
A CYCLICAL INTERPRETATION OF TIME
This essay consists of two parts.
The first addresses the progressive restriction that has surrounded the use of entheogens throughout history, beginning when humanity lived in small communities where the use of these plants was known to all members, moving to strictly guarded access in classical civilizations such as ancient Greece, and culminating in modern Western society, which, after abandoning their use entirely, met their rediscovery with a total prohibition extending even to scientific research.
The second part revives the cyclical interpretation of Time found across non-Western civilizations to sketch a hypothesis regarding the role played by the rediscovery of entheogenic substances within the core of a rationalist culture such as the modern West.
PART ONE
I began this inquiry upon learning that entheogenic substances carried very low physiological toxicity for the body and induced no physical addiction. Furthermore, given the spiritual nature of the experience these substances catalyze, it seemed that every human being, by virtue of their inherent dignity, had a right to such catharsis, if only once in a lifetime. This stood in stark contradiction to official claims propagated by government authorities alleging that these substances represented an enormous hazard to both the individual and society. The situation seemed to produce a senseless and insoluble paradox. Upon discovering that mycophobia—an attitude of deep aversion toward fungi—had been ingrained among most European, Asian, and African peoples for centuries, I considered the possibility that modern prohibition was not an isolated bureaucratic mistake, but part of a deeper historical pattern. Reviewing historical literature, I sought an explanation for the increasingly strict concealment of these substances.
We will begin by defining two fundamental concepts: culture and civilization.
By culture, I mean every distinct mode of perceiving, interpreting, and responding to the surrounding environment. This finds expression in every mythology, and we can understand how a people conceives of life, death, and major existential events through their sacred myths. A devout Christian, whose psychological orientation centers on Jesus Christ, does not perceive reality in the same manner as a member of a secular technocratic society, where dominion over natural resources forms the core around which all thought revolves. Far greater discontinuities appear if we travel to the Amazon rainforest, where we encounter archaic communities for whom all of nature is animated by living spirit, with their daily lives anchored in relationships with the archetypal essences of plants, animals, and weather phenomena.
By civilization, I mean the unification of a broad collective of people under a single shared paradigm, beneath a single overarching culture. A human collective is not merely a geographic perimeter where individuals pursue survival; it is a shared social system, a network of relationships, an economy, a collective destiny, and ultimately, a shared feeling of participation in cosmic existence.
The historical coexistence of divergent cultural frameworks within the same social body has inevitably produced friction, rendering cultural overlap unstable. A matriarchal civilization functions completely differently from a patriarchal one; polygamy stands in opposition to monogamy; an agrarian economy is fundamentally distinct from that of nomadic pastoralists.
Historical examples of the difficulty of multi-cultural coexistence can be seen in medieval Spain, as well as in the former Yugoslavia. In medieval Iberia, Moors, Christians, and Jews coexisted peacefully for long periods while maintaining separate communal spheres (particularly regarding marriage), yet this coexistence ultimately ended in violent fracture with the Reconquista and the forced expulsion of the Jewish community. In communist Yugoslavia, the state attempted to smooth over the deep cultural divergences of its constituent republics, but the collapse of the totalitarian regime revealed that the unifying project had failed, triggering a catastrophic war that stunned Europe. Historically, whenever one civilization has conquered another, its first act following military subjugation has been to dismantle the conquered people’s religion and mythology, around which their collective identity and strength were organized, replacing or subsuming that symbolic system into that of the conqueror.
Here we arrive at the core subject: expanded states of mind. Perhaps the most widespread method of creating and renewing the foundations of an existential worldview is direct access to the realm of Spirit—what modern psychology terms the unconscious. From this visionary source, the shaman, priest, or mystic receives new parameters for communal life, or reaffirms existing ones. When examining animist and totemic traditions, or societies articulating their cosmos through mythological narrative, it is obvious that their insights did not originate from viewing the physical world with the naked eye alone; the great world religions were similarly founded upon the visions and direct revelations of mystics. The conventional Western presumption that these symbolic frameworks represent merely the childish imaginings of an immature human intellect—and that we can safely discard their source—collapses when we observe that foundational cornerstones of our own civilization, such as Einstein’s mass-energy equivalence equation or Descartes’s Discourse on the Method, were explicitly inspired by dreams. Consider Marcus Aurelius, who, speaking of the Eleusinian Mysteries, stated: “The Mysteries gave us life, gave us food; they taught human communities their customs and their laws, and taught men how to live as human beings.” The profound significance of entheogens as catalysts for the visionary imagery that binds human societies was first systematically articulated by anthropologist Peter Furst. The experiential territory they unlock is fundamentally identical in nature to the visions found at the foundation of all cultural systems. From that perspective, entheogens become intrinsically linked, as catalysts of psychic symbolism, to the genesis and renewal of cultural dynamics. Just as every tree is supported by roots invisible beneath the surface, beneath every cultural system lies a matrix of symbols born within expanded states of mind.
Given that a civilization requires a coherent shared cultural paradigm to function cohesively, and that the organic vehicle for generating new cultural visions is direct access to otherness, my central hypothesis is that access to expanded states of consciousness has been systematically controlled, restricted, and repressed as civilizations expanded geographically and demographically. This restriction emerged to eliminate the risk that internal factions might generate divergent paradigms, fostering conflicting worldviews and social fragmentation. Generating sacred mythology and overseeing its interpretation became increasingly monopolized by priestly hierarchies, who appropriated exclusive access to the realm of spirit.
To trace this historical progression, we examine evidence from both historical records and archaic societies that survived into modern times despite encroaching Western globalization. We can divide this historical continuum of entheogenic concealment into three distinct phases, illustrating each with concrete examples.
The first phase may be termed the phase of control or interpretation. We observe it in small, cohesive groups led by the figure of the shaman. This figure specializes in magical healing, maintaining cosmic equilibrium between the mundane world and the spirits (performing rituals of propitiation toward nature and the spirits of hunted game), and orchestrating periodic communal ceremonies where the entire tribe partakes in mystical intoxication to renew collective cultural bonds. In these small-scale societies, every member understands the intoxicating sacrament and its subjective phenomenology. Crucially, the shaman’s role was to delineate and structure the boundaries of the entheogenic experience. As Mircea Eliade noted, mystical states encompass infinite potential spiritual phenomena; while cultural conditioning guides perceptual focus, the unexpected is ever-present. Through pedagogical preparation before the ceremony, mental guidance during intoxication, and retrospective interpretation afterward, the shaman channels and bounds the spiritual symbolism of the initiate.
We find vivid illustrations of this dynamic in Mexico, where an indigenous shaman lamented to Antonin Artaud that the imposition of Western laws had scattered and rendered chaotic the traditional use of peyote, which had previously been restricted strictly to annual collective rituals under his guidance. In an essay on the Bwiti religion, Giorgio Samorini illustrates the classic structure of a small-scale entheogenic society: during initiation, candidates are steered exclusively by senior elders; the architecture of the temple mirrors the sacred mythology; and periodic ceremonies follow three strictly codified liturgical phases blending ancestral African symbolism with Christian syncretism. While the initiate’s subjective experience remains boundless, it is continually anchored by seasoned initiates. Similarly, Peter Furst describes how, prior to Amazonian yagé ceremonies, tribal elders recount ancestral origin myths: the creation of the cosmos, the primordial couple, the social order, and the sacred origin of yagé itself. During the trance, the shaman actively interprets the visions of participants. Examples of structured post-visionary interpretation are ubiquitous.
Here the ritual functions, indelibly, as an instrument of interpretation.
In these intimate societies, the moral authority of the shaman suffices to guide and channel this communion with the sacred.
Subsequently, we encounter larger, more populous civilizations. Classical Greece and Vedic India represent typical manifestations of this second phase. In their archaic formative eras, these societies likely utilized entheogens openly; yet in their classical maturity, the sacraments were obscured, even while the validity of mystical insight remained acknowledged. This marks the entry of institutional mycophobia—an irrational aversion and disgust toward mushrooms. This cultural attitude is entirely unjustified from the standpoint of actual mushroom toxicity, appearing instead to stem from the systematic concealment of psychoactive fungi by priestly castes. Both Greece and India were originally mycophilic cultures (consider the founding myth of Mycenae on the site of a sprouted mushroom, the Vedic soma of the Indo-Aryans, or the classical Greek verse declaring mushrooms the food of the gods). Dionysus himself, who eventually became known as the god of alcoholic intoxication, originated as a divinity of entheogenic ecstasy. (Here one might ponder speculative theories on the role of alcohol in the evolution of consciousness, suggesting that its historical dominance served to numb the magical worldview of archaic societies, paving the way for urbanization and the modern rationalist paradigm.) The Sanctuary of Eleusis exemplifies this Greek compromise: an initiatory temple where mystical revelation was induced, but only following eight months of rigorous philosophical and liturgical preparation; open to all Greek speakers, but permitted strictly once in a lifetime; and governed by severe statutory penalties punishing the illicit use of the kykeon outside the precinct or the disclosure of its sacred rites. From Eleusis to total prohibition required only one further step: locking the temple doors. In India, a parallel dynamic unfolded with the disappearance of botanical soma, replaced by ascetic techniques of yoga that preserved mystical contemplation while rendering it far more sporadic. Gurus and yogis emerged everywhere to interpret and address the spiritual longings of the population.
Classical Greek and Indian civilizations comprised hundreds of thousands of individuals unified under a single mythology, presenting vastly greater challenges to maintaining ideological unity under one overarching paradigm.
The third phase is that of absolute prohibition. We can cite three revealing historical examples. The first is an intriguing hypothesis drawn from the erudite writings of Robert Graves regarding the biblical Exodus from Egypt. Graves proposed that desert manna, when fermented, hosted an ergot-like fungal parasite containing psychoactive alkaloids. This explained Moses’s strict command that manna be gathered fresh daily and never stored overnight. Furthermore, Moses had a golden urn of manna placed inside the Ark of the Covenant as a supreme symbol of Israel’s communion with God. Conflict erupted when, during Moses’s prolonged absence atop Mount Sinai, the Israelites hastily constructed the cult of the Golden Calf. The historical moment was immensely delicate, demanding the consolidation of strict monotheism against ecstatic pagan idolatry.
Christianity, as an imperial faith seeking global dominion, inaugurated its hegemony with the forced closure of Eleusis and the eradication of the Manichaeans, who were suspected consumers of Amanita muscaria. In Coptic Egypt, thousands of hermits seeking visionary illumination in the desert were corralled into cenobitic monasteries under the authoritarian rule of an abbot. In the High Middle Ages, the Inquisition emerged not merely to suppress alleged diabolism, but to systematically uproot all surviving pagan folk practices and herbal lore in rural Europe—a repression subsequently exported to the Americas. Yet within Christian culture, even after physical entheogens were eradicated—supplanted by vast rivers of church wine—the legitimacy of spontaneous mystical states endured. The pivotal figures who periodically revitalized the Church were saints, in each of whom we find records of mystical ecstasy. To control these experiences, ecclesiastical authorities introduced a single decisive inquiry: whether the vision was inspired by God or, if divergent from orthodoxy, by the Devil. Thus the sublime revelations of mystics such as Saint John of the Cross were scrutinized under relentless suspicion; such figures were harassed during life and canonized as Doctors of the Church only long after death (witness the extreme care of Saint Teresa of Ávila in submitting all her writings to the unreserved judgment of the Church). When popular ecstatic movements arose—such as the Flagellants or early Quakers—they faced severe state and religious suppression once they achieved significant followings.
Within institutional Catholicism, interpreting reality fell to bishops—figures lacking personal mystical experience whose authority rested strictly upon biblical scripture.
With the dawn of the Renaissance and the rise of the modern nation-state, secular government supplanted the Church, pursuing rural folk practices and millenarian movements with even greater bureaucratic efficiency. Mystical experience—now more visible than ever—was degraded by state authorities (and their junior partner, mechanistic science) and rejected by the Church. Meanwhile, urban populations, insulated within growing metropolises and severed from the living mysteries of nature, lost all capacity to comprehend visionary language.
The sudden explosion of LSD in the 1960s sparked a cultural counter-movement radically antithetical to the core principles of Western technocratic civilization, embodied in the youth counterculture. Social structures—authority hierarchies, sexuality, work ethics—were overturned overnight; thousands of young people abandoned the consumerist productivity paradigm that had governed their parents’ lives, undertaking spiritual pilgrimages to India and Nepal. The state prohibition of LSD was swift, draconian, and clumsy—scheduling a non-addictive visionary catalyst alongside narcotics and sedatives that posed entirely different societal issues. Within a brief span, street supplies were thoroughly adulterated: of 57 black-market samples analyzed that were sold as synthetic mescaline, not a single one contained any trace of the compound. In the modern era, the task of maintaining civilizational cohesion was transferred to broadcast television and the social prestige of institutional science.
Historical evidence suggests that as a civilization grows in scale, the circulation of entheogens is subjected to ever tighter controls. An altered state of consciousness does not merely reveal the spiritual essence underlying matter; it empowers individuals to renegotiate the foundational pillars of their culture—the timeless pattern of death and rebirth, whereby the initiate sheds outworn structures to embrace an expanded vision of existence. What served archaic communities as an invaluable tool for rapid adaptation and rites of passage became, within sprawling empires, an intolerable threat of social dissolution beyond the control of the ruling priesthood.
PART TWO
We arrive at a pivotal juncture. We have traced the historical concealment of entheogens to a point of near-total prohibition. Yet their role does not appear destined to remain buried in antiquity. Their modern rediscovery has generated profound interest across the West, not only within anthropology and psychiatric medicine, but throughout civil society, witnessing its cultural big bang during the 1960s. The vehement political reaction of state authorities demonstrates that these catalysts of consciousness are far more than quaint folklore. Furthermore, entheogens offer a powerful mirror for examining the modern dilemma: having constructed the formidable edifice of rational science and technological engineering, Western civilization finds itself trapped in a worldview experienced simultaneously as a triumph and an existential threat—the blind hope of Prometheus reborn.
To contextualize our contemporary crisis, we return to the cyclical conception of Time preserved across indigenous cultures. Ancient civilizations understood existence as a perpetual succession of unfolding cosmic cycles—arising, flourishing, decaying, and giving birth to new stages in the ongoing creation of the cosmos. In the West, this cyclical rhythm was replaced by linear time, severing our connection to the seasonal rhythms of day and night, growth and dormancy. Western civilization conceptualized history as indefinite linear progress without organic transitions. While the cyclical model mirrors the breathing rhythms of nature, linear progress resembles an accelerating automobile hurtling forward without speed limits. The obvious danger of the linear paradigm is that the engine overheats or slams into an unforeseen wall, ending history abruptly. Conversely, traditional cyclical views can be critiqued for understating qualitative development across eras.
Employing the cyclical paradigm allows us to examine the birth, zenith, and twilight of cultural epochs, while synthesizing this perspective with linear progress by incorporating the enduring discoveries of modern science into the spiral of human evolution.
To illuminate this transformative passage, we may examine a profound Lakota Sioux myth articulating this cyclical cosmology.
According to Lakota tradition, at the dawn of creation a great cosmic buffalo was positioned at the edge of the world to hold back the primordial waters threatening to submerge the earth. With each passing year, the buffalo loses a single hair from its coat; once bare, it loses one of its four legs, regrowing its coat only to repeat the process until all four limbs are lost. At the beginning of the cycle, humanity lived in complete harmony with creation; with each loss of hair and limb, this sacred communion diminished. When the buffalo loses its fourth leg, the cosmic waters will engulf the earth, bringing an end to life as a consequence of humanity’s severed relationship with the cosmos. Parallel myths appear in Vedic India (with the sacred cow of Dharma losing its legs across the Yugas) and among the Sámi of northern Scandinavia, who envision the world suspended by four cosmic cords fraying over time. (Notably, when native elders recounted these legends to early ethnographers, they insisted the world was already clinging to a single, heavily frayed cord.) The cyclical paradigm concludes the myth not with absolute annihilation, but with cosmic renewal following catastrophe, inaugurating a new golden age of harmony between humankind and the cosmos.
Every living myth conceals a profound psychological and spiritual reality often invisible to modern observers. This difficulty is magnified when viewed through contemporary Western eyes, which abandoned mythological thought in favor of mechanistic materialism, conflating the Real with the purely Physical. Archaic thought focused instead on the reality of the soul, which possesses its own autonomous dynamics and exerts a profound influence on the unfolding of human history.
Deciphering myth requires a symbolic key. To modern minds, ancient legends read like children’s fairy tales because we attempt to map them literally onto physical geography. However, if we translate their symbols into psychological equivalents, their meaning becomes strikingly lucid. In apocalyptic prophecies, if we replace physical destruction with the collapse of an outworn perceptual model—the death of an old paradigm—the narrative becomes profoundly plausible. What perishes is not the physical planet, but our conceptual representation of it. Indeed, the historical transition from the animist vision of archaic peoples to mechanistic Cartesian physics was itself a total transformation of our experiential reality. A synthesis of both perspectives would represent an even greater evolutionary leap. Thus, rather than physical death, we are contemplating a profound psychic transformation.
The architecture of the modern worldview expanded dramatically during the Renaissance, though its seeds were planted in classical Greece when rational philosophy supplanted magical animism. We can summarize the foundational pillars of our civilization in the ideas of three seminal thinkers: Descartes, Kant, and Machiavelli.
Descartes established the foundations of the scientific method, an analytical framework enabling exhaustive scrutiny of the physical, material realm. In the 19th and 20th centuries, this empirical knowledge became embodied in industrial technology through pioneers like Edison and Ford; science discovered its practical arm in engineering.
Immanuel Kant articulated another defining axiom of our culture. In his critical philosophy, he investigated the boundaries of human epistemology: what can be rigorously known, and what remains inaccessible to intellect. Fascinated by Newtonian mechanics, he explored sensory perception in relation to scientific laws. In this framework, the possibility of direct, intuitive knowledge of transcendent reality—failing to fit empirical verification—was excised from legitimate philosophy. Kant concluded that religion could never be grounded in pure reason. Transcendent, numinous insight was thus relegated to subjective, voluntary faith—if not dismissed as quaint folklore.
Niccolò Machiavelli symbolically represents the definitive severance of political governance from spiritual accountability. Through the Middle Ages, temporal rulers remained subordinate to religious authority. Machiavelli’s Prince answered to no higher moral arbiter, navigating statecraft solely by pragmatism and raison d’état, with instrumental reason as his sole compass.
What humanity discovered was the extraordinary power of observing, calculating, and manipulating the material universe. Nature ceased to appear as an intimidating threat, giving rise to the intoxicating ambition that humankind might completely predict and master all natural processes. The mathematical laws uncovered by science allowed human beings to design new environments, stepping into the role of a creator shaping the world to its own specifications.
Yet the reign of technical rationality brought more than powerful tools: it established an entirely new cosmology. The Church, which had previously held custody over reality, resisted fiercely, initiating a centuries-long war between faith and science. Christianity, ossified into rigid dogma, could defend itself only through tradition; meanwhile, the empirical triumphs of science proved irresistible. Because mystical experience was absent from the debate, a fruitful synthesis between the sacred and the rational proved impossible: institutional religion could not adapt quickly enough, and secular science, blind to mystical insight, could not comprehend spiritual reality. A new mythological pantheon was born: the electron ascended to primacy, while the Virgin Mary retreated into history.
This paradigm shift broke with Western religious tradition, but it also constituted an unprecedented rupture with millennia of human experience. Where past cultures anchored themselves in spiritual cosmologies, modernity swung to the opposite extreme: a cosmology exclusively grounded in the material plane. This cultural shift finds an intriguing cultural illustration in comparing classical comic archetypes: the village druid in Astérix transforms into the rationalist professor in Tintin; the tribal chieftain becomes the modern bureaucratic state; and the sacred Amanita muscaria of the druid’s cauldron is replaced by Captain Haddock’s numbing whiskey.
The contemporary Western worldview provides an exhaustive cartography of physical space while leaving humanity devoid of a map for the soul. It assumes that mastering the external environment satisfies every human need, forgetting that human beings must also relate to their internal reality. The avenues to physical exploration are wider than ever, yet we have shuttered the pathways to our own psychic depths. Western man understands quantum physics but remains a stranger to himself. The buoyant 19th-century optimism of endless material progress has faded, replaced by pervasive existential anxiety regarding our collective future.
Ernst Jünger observed that during eras when spiritual authorities lose credibility, one must look to artistic creation to discern a civilization’s prophetic intuitions. While intuitive insight historically flowed from the deep contemplation of mystics, in secularized ages it is art that reflects the psychic currents of society. Cinema, the iconic art of the 20th century, has produced works reflecting profound internal distress and existential risk. The masterpieces of Eisenstein, Charlie Chaplin’s Modern Times and The Great Dictator, or speculative mythologies such as Star Wars and Planet of the Apes, directly mirror underlying collective anguish. James Joyce’s landmark novel Ulysses depicts modern man wandering through the labyrinth of his own psyche, alienated from himself and disconnected from the surrounding world.
Even within mainstream science, visions emerge that mirror the warnings of Lakota prophecy. Astronomer Carl Sagan cautioned that technologically advanced civilizations may carry an inherent risk of self-annihilation. Here, apocalyptic foreboding is no longer merely psychological; it is projected onto physical reality. The historical specter of nuclear holocaust—now joined by ecological collapse—confronts human consciousness with the tangible possibility of planetary extinction. Yet the choice remains ours: whether to deploy our technologies for destruction or for conscious renewal.
Returning to Jünger, we find another compelling mythological assessment of the technological era: observing the rise of technics as the planetary language, he suggested that the displacement of sacred religion by technology represents the replacement of the Gods by the Titans—beings indifferent to the human soul embodying mechanistic efficiency. Computers and economies centered on endless productivity threaten to enslave humanity rather than liberate it. (The substitution of the church cross by the wristwatch is highly symbolic in this regard.)
Consequently, the future envisioned by humanity carries far more anxiety than hope. Science has charted the cosmos, but left the human soul an arid desert devoid of living myths to confer meaning. Having established dominion over nature, our despotic relationship with the living biosphere now rebounds against our own survival. In this precarious moment, the ancient Lakota myth echoes across the centuries, warning of severed harmony with creation that culminates in civilizational collapse.
Yet the 20th century was not solely an era of technological acceleration and Western hegemony; it also planted the seeds for the rediscovery of the spirit, newly conceptualized as the unconscious. While initially modeled in purely rational terms, depth psychology gradually recognized that the unconscious houses the transcendent archetypes once articulated by sacred religion. The rediscovery of entheogens has provided an empirical instrument granting direct experiential access to this sacred dimension of the psyche, demonstrating that visionary states are not primitive delusions, but authentic expressions of our deepest being (“I sought you outside myself, when in truth you dwelt within,” observed Augustine of Hippo in the 4th century). It is as if the historical endeavor of the past several millennia was to isolate waking consciousness from the vast ocean of the soul, sharpening analytical reason to forge science and technology. This achievement represents an extraordinary human triumph; yet divorced from the wholeness of the psyche, it becomes a perilous machine lacking ethical purpose—a headless giant. Restoring the living bridge between technical intellect and sacred spirit is the sole path ensuring that technological power serves human liberation rather than mechanistic enslavement.
Here we recall the profound insight of Richard Tarnas regarding Hegel: humanity truly comprehends the full meaning of what it has created only after the work has reached completion.
EPILOGUE
The contemporary condition of humanity mirrors the biblical myth of Lucifer: believing itself self-sufficient, it asserted independence from the rest of creation, only to discover that this isolation threatens its own survival unless it reunites with the sacred whole.
C. G. Jung, who introduced the concepts of archetypes and the collective unconscious to modern thought, titled his final monumental work Mysterium Coniunctionis. In it, he argued that resolving the civilizational crisis of the West—the clash of opposites—could never be achieved through the triumph of one pole over the other, but through their conscious integration. Thus the conflict between technology and spirit, good and evil, East and West, masculine and feminine, conscious intellect and the unconscious, linear time and cyclical renewal, finds balance through harmonious synthesis, opening a transformative horizon for the future while illuminating the wisdom of the past.
Gottfried Benn, contemplating the acute existential pain of the modern era, initially contemplated a retreat into archaic nostalgia. Yet he soon realized there is no turning back: the only path lies forward, through the very heart of the modern dilemma, even when the portal ahead appears framed in consuming fire. The crisis confronting modern humanity is the universal ordeal of the initiatory rite of passage: one must willingly die to what is outworn in order to be reborn into the new.
Because the gravest danger confronting humanity stems not from the physical cosmos, but from an internal psychological collapse, the rediscovery of entheogenic sacraments pioneered by figures like R. Gordon Wasson may well represent one of the vital seeds of human renewal.
