Back to: The Hermetic Laws & Quantum Physics
Essential Question 1: What Is Hermeticism, and Why Has It Persisted for Millennia?
The Short Answer
Hermeticism is a family of philosophical, religious, and practical teachings traditionally attributed to the legendary figure Hermes Trismegistus, a syncretic fusion of the Greek god Hermes and the Egyptian god Thoth. At its core sits a small body of Greek texts written in Roman-era Egypt between roughly the first and third centuries of the common era. Around this core, a much larger literature of alchemical, astrological, magical, and philosophical texts accumulated across the medieval Arabic world and the Renaissance Latin West. Hermeticism has persisted for nearly two thousand years because it addresses questions that do not age: the nature of reality, the relationship between mind and matter, the possibility of human transformation, and the structure of the cosmos.
The Longer Answer
To understand why Hermeticism has survived, you need to understand what it is. Most students arrive in this course with a vague sense that Hermeticism is “ancient Egyptian wisdom.” That picture is partially right and significantly misleading. Let me give you the picture that contemporary scholarship supports.
The foundational documents of the tradition are the seventeen treatises known as the Corpus Hermeticum. According to the best scholarly consensus, these were written in Greek, in the Greco-Roman Egypt of the first through third centuries of the common era, most likely by Hellenizing members of the Egyptian priestly class whose intellectual life centered on the temples of Alexandria and the Nile Delta. The texts fuse Egyptian religious sensibility with Middle Platonic and Stoic philosophy, with some influence from Jewish thought and the broader religious ferment of the period that also produced Neoplatonism, Christianity, and the various movements we now lump together as Gnosticism. They are not the writings of a single ancient sage. They are the literary output of a milieu, and the figure of Hermes Trismegistus is a composite created by that milieu rather than a historical person.
Alongside the Corpus Hermeticum sits the Emerald Tablet, a short and cryptic text that gave us the most famous Hermetic axiom: “As above, so below.” The history of the Emerald Tablet is very different from that of the Corpus Hermeticum. Its earliest surviving versions appear in Arabic mystical and alchemical treatises between the eighth and tenth centuries, most notably in the Book of the Secret of Creation attributed to Apollonius of Tyana. From Arabic the text was translated into Latin in the twelfth century, most likely by Plato of Tivoli working in Barcelona around 1134 to 1145. From there it entered the bloodstream of European alchemy and Renaissance natural philosophy, where it became the foundational text of the alchemical art. Isaac Newton, in the late seventeenth century, produced his own English translation of the Emerald Tablet and preserved it among his voluminous alchemical manuscripts.
The third text most people associate with Hermeticism is the Kybalion. This is where scholarly honesty becomes essential. The Kybalion was published in 1908 by the Yogi Publication Society in Chicago under the pseudonym “Three Initiates.” The religious historian Philip Deslippe, whose scholarly edition remains the definitive account, has established that the actual author was almost certainly William Walker Atkinson, a prolific New Thought writer, attorney, and publisher who routinely wrote under multiple pseudonyms. The “ancient Hermetic text” that the Kybalion claims to quote does not exist. The book is a genuine product of early-twentieth-century New Thought philosophy, influenced by older Hermetic currents but also heavily shaped by the spiritual climate of turn-of-the-century America. Scholars have noted significant contrasts between the Kybalion and the authentic Hermetica, including the Kybalion’s relatively anti-theological stance versus the heavy theological emphasis of the original Greek texts.
I want to be clear about what this means and what it does not mean. It does not mean the Kybalion is worthless. Its seven principles articulate genuine insights that resonate with parts of the older Hermetic tradition and that have proven spiritually useful to a century of readers. It does mean that when we use the Kybalion as our primary reference point, we are working with a modern synthesis, not an ancient source. This is one of the first applications of the principle of precision that will run through the whole course. If you want to know what authentic ancient Hermeticism taught, you read the Corpus Hermeticum, preferably in Brian Copenhaver’s scholarly translation. If you want to know what the early American esoteric revival did with the Hermetic legacy, you read the Kybalion. Both are legitimate objects of study. They are not the same thing.
Why It Has Persisted
Hermeticism has survived two millennia because it keeps getting rediscovered. The pattern is remarkable. The Greek Hermetica were preserved by Byzantine scholars while most of the Western world forgot they existed. The Emerald Tablet was kept alive by Arabic alchemists during centuries when Europe had largely lost interest. In 1462, the Florentine scholar Marsilio Ficino interrupted his translation of Plato to render the Corpus Hermeticum into Latin at the request of his patron Cosimo de’ Medici, setting off a Renaissance Hermetic revival that influenced Giordano Bruno, Robert Fludd, Johannes Kepler, and the founders of the Royal Society. In the twentieth century, Carl Jung read the Emerald Tablet as a symbolic description of psychological individuation, giving the tradition a new life in depth psychology.
Why does it keep coming back? Because the questions it asks do not get answered by the cultural trends that periodically try to bury them. What is the relationship between mind and matter? Is there a structural unity beneath the diversity of phenomena? Can human beings undergo genuine inner transformation, and if so, how? Whenever a civilization convinces itself that these questions have been settled or that they don’t matter, another generation comes along that finds them urgent again. Hermeticism is the tradition that keeps those questions alive. That is its function. That is why it persists.
Essential Question 2: What Is Quantum Physics, and Why Does It Disturb Our Intuitions about Reality?
The Short Answer
Quantum physics is the branch of science that describes the behavior of matter and energy at the smallest scales we can investigate: atoms, subatomic particles, photons, and the fundamental fields from which these emerge. It is the most precisely tested theory in the history of science. It also describes a reality that behaves nothing like our everyday experience, and the attempt to make sense of why has generated more than a century of genuine philosophical disagreement among the physicists themselves.
The Classical Worldview It Replaced
To understand why quantum physics was so disturbing, you have to understand what it replaced. For roughly two centuries, from Isaac Newton’s Principia in 1687 to the end of the nineteenth century, the educated Western world operated within a picture of reality we now call classical physics. The universe was a clockwork. Every object had definite properties at every moment, whether anyone observed them or not. Every effect had a specific cause. If you knew the positions and velocities of all the particles in a system, along with the forces acting on them, you could in principle predict the entire future and retrodict the entire past. Pierre-Simon Laplace famously imagined a sufficiently powerful intelligence that would see the future and the past simultaneously in a single mathematical act. The observer was an outside witness who could be cleanly separated from the observed.
This was not merely one philosophical option among many. It was the atmosphere in which Western intellectual life breathed for two hundred years. The successes of classical physics in astronomy, mechanics, thermodynamics, and electromagnetism were genuinely staggering. By 1890, many physicists believed the fundamental work of their discipline was essentially complete. A few loose ends remained. The spectrum of radiation emitted by hot bodies, the strange photoelectric effect, the unexpected stability of atoms. These were assumed to be minor housekeeping problems. They turned out to be the cracks through which an entirely new universe would pour.
The Cracks Become the Revolution
On December 14, 1900, at a meeting of the German Physical Society in Berlin, Max Planck presented a derivation of the blackbody radiation spectrum that required him to assume that energy could only be emitted or absorbed in discrete packets, which he called “quanta.” Planck himself considered the assumption a mathematical trick rather than a statement about physical reality. He spent the next decade trying to find a classical derivation that would render the quantum hypothesis unnecessary. He never succeeded.
In 1905, Albert Einstein took Planck’s quanta literally. In a paper explaining the photoelectric effect, the work for which he would later receive the Nobel Prize, Einstein proposed that light itself comes in discrete particles of energy, which we now call photons. Light, which Maxwell had shown beyond any reasonable doubt to be an electromagnetic wave, was now also a stream of particles. Wave-particle duality had entered the world. Nothing would ever be quite the same.
Over the next quarter century, from roughly 1900 to 1927, a remarkable generation of physicists; Planck, Einstein, Niels Bohr, Louis de Broglie, Werner Heisenberg, Erwin Schrödinger, Max Born, Pascual Jordan, Paul Dirac, and John von Neumann, built the mathematical framework of modern quantum mechanics. The key milestones included Bohr’s model of the atom in 1913 with its discrete energy levels, de Broglie’s 1923 proposal that matter itself has wave properties, the independent 1925 development of matrix mechanics by Heisenberg with Born and Jordan and wave mechanics by Schrödinger, Born’s 1926 recognition that the wave function gives probabilities rather than a literal distribution of matter, and Heisenberg’s 1927 formulation of the uncertainty principle showing that certain pairs of properties cannot be simultaneously known with arbitrary precision.
By 1930, the mathematics was essentially complete. It worked. It made predictions of stunning accuracy. It unified a huge range of phenomena. Quantum mechanics would go on to become the foundation of modern chemistry, electronics, materials science, and telecommunications. The computer you are reading this on exists because quantum mechanics is true. There is no serious scientific doubt about the mathematical formalism.
What Disturbed the Founders
And yet the founders themselves were often deeply disturbed by what they had created. The mathematics worked, but the picture of reality it implied was, as Niels Bohr put it, one that nobody who was not shocked by it had really understood. Consider what the theory seemed to say.
It said that before measurement, quantum systems do not have definite properties. An electron is not, in general, at a particular place with a particular velocity. It is described by a wave function that gives probabilities for various outcomes, and according to the standard interpretation, these probabilities are not reflections of our ignorance but features of nature itself. Einstein hated this. “God does not play dice with the universe,” he famously wrote. He spent the rest of his life searching for a deeper deterministic theory beneath quantum mechanics. He never found one.
The theory said that the act of measurement somehow plays a special role. In the double-slit experiment, particles behave like waves when their paths are not determined, and like particles when they are. Schrödinger devised his famous thought experiment of the cat in a box precisely to dramatize how absurd this seemed. If a radioactive atom in a sealed box has a fifty percent chance of triggering a poison that kills a cat, then according to the standard reading of quantum mechanics, the cat before we open the box is in a superposition of alive and dead. Schrödinger intended this as a reductio ad absurdum, a proof that something must be wrong with the interpretation. Nearly a century later, physicists still haven’t agreed on what that something is.
The theory said that entangled particles remain correlated across arbitrary distances in ways that cannot be explained by any local mechanism. Einstein called this “spooky action at a distance” and considered it proof that quantum mechanics must be incomplete. In 1964 John Bell proved mathematically that no local hidden variable theory could reproduce quantum predictions, and from Alain Aspect’s experiments in 1982 through the 2022 Nobel Prize-winning work of Aspect, John Clauser, and Anton Zeilinger, the experimental evidence has only confirmed that nature actually is this strange.
The Interpretive Problem
This is why physicists still argue about what their own equations mean. The mathematics of quantum mechanics is not in dispute. The experimental predictions are confirmed to parts per billion in some cases. What is in dispute is what the mathematics is telling us about reality. The candidate answers, which we will examine in depth in Module 2 and which readers of the Module 5 guide in this course have already encountered, include the Copenhagen interpretation, the Many-Worlds interpretation, the de Broglie-Bohm pilot wave theory, Quantum Bayesianism or QBism, Relational Quantum Mechanics, the Decoherence framework, the Von Neumann-Wigner consciousness-collapse view, and Penrose-Hameroff Orchestrated Objective Reduction, among others.
Each of these interpretations is compatible with the same experimental data. Each tells a radically different story about the nature of reality. Some assign consciousness a central role in physics. Others assign it none at all. No experiment has definitively decided among them. This is not a scandal. It is the actual state of the field, and it is one of the most philosophically significant facts in all of science.
Essential Question 3: Are These Two Traditions Describing the Same Reality from Different Vantage Points, or Is the Apparent Convergence Illusory?
The Short Answer
We do not know yet, and the honest answer cannot be given in Module 0. What we can say, before we have done the detailed work of Modules 2 through 8, is that the question is genuine and that the convergence is not trivially illusory. Some of the greatest physicists of the twentieth century thought they were seeing something real. Some of the most rigorous philosophers have thought so too. Others have thought the convergence is a kind of optical illusion created by loose vocabulary. Both positions are held by serious people, and the decision between them requires more tools and more knowledge than we can muster at the starting line.
What the Founders Themselves Noticed
Here is something worth sitting with. The physicists who built quantum mechanics were, as a group, unusually interested in the wisdom traditions of the East and in the philosophical mysticism of the West. This is a matter of historical record, not speculation. Niels Bohr adopted the Daoist yin-yang symbol as his personal coat of arms when he was knighted in 1947, with the motto “Contraria sunt complementa.” Opposites are complementary. Werner Heisenberg had extended conversations with the Indian poet and philosopher Rabindranath Tagore, and told Fritjof Capra decades later that these conversations had helped him come to terms with the strangeness of quantum mechanics by showing him that an entire culture had been saying something structurally similar for a long time. Erwin Schrödinger was a lifelong student of Vedanta and the Upanishads, and wrote in My View of the World that consciousness is singular, not plural. A thoroughly Vedantic position from the man who gave us the wave equation. Wolfgang Pauli collaborated for decades with the psychologist Carl Jung on questions of synchronicity and the unus mundus, the underlying unity of mind and matter.
None of this proves anything about the truth of the Hermetic principles. But it does establish that the convergence was noticed by the people best positioned to notice it. These were not marketing consultants selling “quantum healing” on Instagram. These were the builders of the theory itself, and they thought there was something there. That deserves our attention.
Why the Convergence Might Be Illusory
It must also be said that the apparent convergence has been aggressively oversold for at least fifty years, and that serious critics have raised legitimate concerns. Fritjof Capra’s The Tao of Physics, published in 1975, was the book that brought the physics-mysticism parallel into popular consciousness. It is a genuinely important book and a genuinely problematic one. Critics like the mathematical physicist Peter Woit and the physicist Jeremy Bernstein have pointed out that Capra relied heavily on the “bootstrap model” of strong-force interactions, which was superseded by the Standard Model of particle physics around the time his book appeared and has never been restored to scientific credibility. Other critics have argued that Capra relied on vague linguistic similarities rather than demonstrable structural correspondence. Still others have pointed out that Capra’s sampling of Eastern philosophy was highly selective, picking the traditions and interpretations that best fit his thesis and quietly setting aside the many others that do not.
These criticisms are legitimate. They do not settle the matter, but they mean that we cannot simply assume the parallelism thesis is established. We must do the work. That is what the three-level correspondence framework is for.
Essential Question 4: What Intellectual Tools Do We Need to Investigate This Question Honestly?
The Short Answer
We need a framework for distinguishing genuine isomorphism from deep analogy from false correspondence. We need working familiarity with a few classical logical fallacies that are especially common at the intersection of science and spirituality, notably the genetic fallacy and the fallacy of equivocation. And we need two interpretive principles that most people skip right over: the principle of charity and the principle of precision. Section 5 of this guide develops all of these in detail. Here I want to introduce them briefly, so you know what the map looks like.
The Three-Level Correspondence Framework
This framework is the single most important intellectual tool in the course. Every proposed parallel between a Hermetic principle and a scientific concept gets sorted into one of three categories.
Level 1 is genuine isomorphism: the two claims are describing the same structural relationship, such that a precise translation from one vocabulary to the other is possible and the comparison makes testable predictions.
Level 2 is deep analogy: the two claims are structurally similar in illuminating ways, but they operate in different domains or through different mechanisms, so the comparison generates insight without identity.
Level 3 is false correspondence: the two claims merely share vocabulary or superficial imagery, and the comparison breaks down under any serious analysis. It is crucial to realize that Level 3 is not an insult. Plenty of intelligent people have fallen into Level 3 comparisons in good faith.
Recognizing the category is what protects the inquiry.
The Two Fallacies
The genetic fallacy is the error of judging a claim by its origin rather than its content. If someone says “Hermeticism is ancient wisdom, therefore it must be true,” they are committing the genetic fallacy in the direction of validation. If someone says “the Kybalion was written in 1908 by a New Thought author, therefore its principles are worthless,” they are committing the same fallacy in the direction of dismissal. Both moves skip the actual question, which is whether the claim corresponds to reality regardless of where it came from.
The fallacy of equivocation is using a single word in two different senses within the same argument. This one is catastrophic at the physics-mysticism interface. When a physicist says “observation,” she usually means “physical interaction that produces a record.” When a spiritual teacher says “observation,” he usually means “conscious awareness.” These are not the same thing. Sliding between them without noticing is how “quantum mechanics proves consciousness creates reality” gets manufactured. The same problem haunts “vibration,” “energy,” “frequency,” “entanglement,” and nearly every other piece of vocabulary the two traditions share. Watching for the equivocation is a lifelong skill. We begin developing it here.
The Two Principles
The principle of charity says that before you critique a position, you represent it in the strongest possible form its defenders would endorse. You steel-man, not straw-man. If you are going to evaluate the Hermetic Principle of Mentalism, you do not evaluate the Instagram version. You evaluate the version that Plotinus or Schrödinger or Kastrup would defend. Only then does your critique have any value.
The principle of precision says that before you compare two terms from different traditions, you pin down exactly what each one means in its native context. “Vibration” in quantum field theory is a mathematically specified oscillation of a field with a definite frequency and amplitude. “Vibration” in popular spirituality is often a felt quality of energy that has no specified relationship to anything measurable. You may still want to compare them. But you will compare them honestly only if you first get the definitions clear. Precision is not pedantry. It is how respect for both traditions shows up in practice.
Hold these four tools, the three-level framework, the two fallacies, and the two principles, and you have the minimum kit for what we are about to do. Sections 5 and 7 of this guide give you practice applying them. The rest of the course assumes you have them.
