Wolfgang Pauli (1900–1958) received the 1945 Nobel Prize in Physics. He was one of the founding fathers of quantum mechanics, feared in scientific debate ("the wrath of God", colleagues called him), famous for a bizarre side phenomenon – the "Pauli effect", in which equipment broke in his vicinity. What few people know: Pauli worked with C. G. Jung for more than two and a half decades, had around 1,500 of his dreams recorded, and developed jointly with Jung the concept of synchronicity – a unified reality in which psyche and matter are two sides of the same real.
An unusual double role
Pauli was no esotericist. He was at the very top of mathematical physics – the Pauli exclusion principle, the prediction of the neutrino in 1930, the theory of spin. At other physicists' lectures he could take a whole theory apart with a single sentence. This same man pursued for decades the question whether 20th-century quantum mechanics and Jung's depth psychology might in fact be two descriptions of the same underlying reality. And he engaged openly with phenomena that gave most of his colleagues stomach pains: telepathy experiments, dreams full of alchemical symbolism, the "Pauli effect" itself.
The Pauli effect
Among physicists in the first half of the 20th century, the "Pauli effect" was a small legend: in Pauli's presence, equipment broke down without apparent cause. Vacuum tubes imploded, devices caught fire, experiments suddenly failed. Otto Stern, one of the most prominent experimental physicists of his time, is said to have banned Pauli from his Hamburg laboratory. A famous episode: in 1948, an apparatus in a Göttingen laboratory blew up unexpectedly – and as it later turned out, exactly at the moment when Pauli's train, on its way to Zurich, was stopped at Göttingen station.
Pauli himself did not see this as a mere quirk. With his long-time colleague Markus Fierz he openly discussed the phenomenon as a possible sign of an unconscious psychophysical influence – that is, a form of the psyche acting on matter that the classical concepts of physics cannot capture. Precisely this question runs through his entire later collaboration with Jung.
1932: the crisis and the path to Jung
In 1927 Pauli's mother had taken her own life, his father remarried shortly afterwards, in 1929 Pauli left the Catholic Church, in 1929/30 his short first marriage was dissolved, and alcohol became a problem. In early 1932 the by then 31-year-old top physicist turned to C. G. Jung. Jung did not take Pauli into analysis himself but sent him to his student Erna Rosenbaum in Berlin – with the instruction to record the dreams initially without any influence from Jung. Over months an unusually rich dream diary emerged.
Jung was fascinated. What the atheist, strictly rational quantum physicist was bringing up was full of ancient symbols – alchemical images, mandala-like structures, mythological figures – which Pauli demonstrably had never studied. For Jung this was a "live demonstration" of his thesis of the collective unconscious and the archetypes. Within a few years the patient-analyst configuration grew into a scientific friendship between equals, continued through a dense correspondence until Pauli's death in 1958.
Around 1,500 dreams and the "World Clock"
Between 1932 and around 1934, some 1,300 to 1,500 of Pauli's dreams were documented; an excerpt of about 400 was published anonymously by Jung in 1935 in Dream Symbols of the Individuation Process and later integrated, in revised form, into Psychology and Alchemy (1944). Pauli is not named – his identity only became public after his death.
The most famous of these dreams is the "Great Vision of the World Clock": Pauli sees two interpenetrating circles standing perpendicular to each other, sharing a common centre, divided into four quadrants, with a threefold rhythm. Pauli described the vision as "the greatest harmony", as a deep and unspeakable impression of reality. Jung read the image as an archetypal mandala – an early form of precisely the "unus mundus" concept that Pauli and Jung would later develop.
"It was the greatest harmony. – An impression of the 'sublime harmony' of the cosmos, which gave me a feeling of deepest security."

Synchronicity – the joint concept (1952)
In 1952 the joint book by Jung and Pauli appeared: Naturerklärung und Psyche ("The Interpretation of Nature and the Psyche"). It contains two essays. Jung's: Synchronicity as a Principle of Acausal Connections. Pauli's: The Influence of Archetypal Ideas on the Scientific Theories of Kepler.
The concept of synchronicity was developed jointly: the occurrence of two or more events that are not connected by cause and effect, but which form a deep meaningful connection for the observer. Pauli helped Jung give the concept a physically defensible frame. In their late correspondence they discuss a four-dimensional model of reality:
- Space and time (what classical physics describes),
- Causality (cause and effect),
- Synchronicity – as a non-causal but meaningful link between psyche and world.
Unus Mundus: the unified reality
The actual metaphysical aim of the two was even more fundamental, however. Pauli and Jung took up from medieval alchemy the concept of the unus mundus – "one world": the thesis that psyche and matter are not two separate domains but two manifestations of one, deeper reality. Pauli explicitly saw a connection here to quantum mechanics – especially to the question of what it actually means that a quantum state "collapses" upon measurement and that the observer is entangled in this process.
This makes Pauli a central historical bridgehead between the question "How are consciousness and matter connected?" and the modern discussion we take up in our pieces on consciousness and the brain and on matter and the Higgs field. Anyone who treats materialist reductionism as identical with "science" has a problem with Pauli: one of the most important quantum physicists of the 20th century publicly disputed exactly that.
Pauli and parapsychology (Rhine, telepathy)
Pauli followed the experimental work of Joseph Banks Rhine at Duke University (Zener cards, telepathy tests) with interest. In his correspondence with Jung he discusses whether the statistical deviations Rhine found in his trials might be related to the quantum-mechanical concept of probability – that is, whether the non-locality demonstrated in quantum physics might be the physical sibling of the psychological synchronicity.
This did not make Pauli a credulous spiritualist. He was a methodologically strict sceptic – but one who would not ignore serious findings just because they failed to fit the prevailing frame. Precisely this stance – critical and at the same time open – would still be needed today in the debate about majority opinion vs. expert opinion.
Pauli and Kepler – archetypes in the history of science
Pauli's own essay in the 1952 volume is today less well-known than Jung's synchronicity paper, but it is methodologically remarkable. Pauli examines how Johannes Kepler in the early 17th century developed his heliocentric model of the solar system – and arrives at the finding that Kepler was guided in essence by an inner, mandala-like image (the "sphaira"), an archetypal symbol of threeness (Sun, fixed stars, intervening space). Pauli concludes: even in the hardest of natural sciences, archetypes shape the formation of theory – not just data and logic. An unusual position for a Nobel laureate.
Late position: between rationality and "lucid mysticism"
In the last years of his life Pauli engaged intensively with alchemy, Gnosis, Kepler and the question why modern natural science had lost the anima mundi – the "world soul" of antique and medieval tradition. He sought what he himself called "lucid mysticism": a synthesis of mathematical rigour and a deeper reality, without sliding into esotericism. For mainstream physics after 1958 this part of his work was for a long time taboo. Only since the full edition of the Pauli–Jung correspondence (1992) and the growing attention to quantum-consciousness models has Pauli's late work begun to be discussed seriously again.
Why Pauli matters for mediumship
- Scientific credibility. Pauli is not "someone who happens to believe something" but a Nobel laureate in physics. His argument for the reality of non-causal connections between psyche and world is fed not by esotericism but by quantum physics.
- The bridge to Jung. Without Pauli, Jung's synchronicity theory would have remained a purely psychological concept. With Pauli it became a serious question put to natural science.
- The Pauli effect as data point. A phenomenon documented over decades by independent observers, which resists conventional explanation – and which the person concerned did not explain away but investigated.
- Continuity with current debates. Quantum entanglement, the observer effect, consciousness models in physics – the line Pauli drew is highly relevant again today.
Pauli shows that the separation "hard science here, soft paranormal there" is a cultural choice, not a scientific necessity. Anyone who engages seriously with mediumship, synchronicity and the psyche–matter relationship will sooner or later run into Pauli.
