Liminal Resonance, with Joachim Keppler
"Consciousness is not a product of biological evolution and, hence, not a cosmic latecomer. Quite the contrary, consciousness is a fundamental feature of the universe."
Few questions sit as close to the edge of both physics and philosophy as the nature of consciousness.
Does our conscious agency function as a receiver to its environment, or a transmitter of actions and intentions that carry it through space and time?
Is awareness an emergent byproduct of complex neural activity, or does it reflect a deeper coupling between the mind and the fabric of reality?
Joachim Keppler’s work occupies the liminal territory that these questions drag our curiosity to and through.
Drawing from quantum field theory, cosmology, and neuroscience, Keppler has proposed that conscious states arise through a resonance-like interaction between the brain and what’s known as a zero-point field— the lowest possible energy state of any given system.
“We are not only observers. We are participators. In some strange sense, the universe is a participatory universe.”
— John Archibald Wheeler
The zero-point field (colloquially known as ZPF) is gaining more traction amidst increasing verification via experiments (i.e. Casimir Effect) or theories to explain how empty space is never really empty (i.e. Lamb Shift).
The main question is to what extent the ‘empty’ background - the vacuums of reality - actually participate, resonate and welcome coherent interactions.
It’s an idea that challenges conventional materialist accounts while remaining grounded in physical law, while stretching perceptions beyond anything that can be measured in the ephemeral overlaps between physics and consciousness/science and psyche.
What we call ‘nothing’ is actually seething, structured, dynamic, and maybe more meaningful than we might think; so how does our consciousness interact with it?
You propose that consciousness arises from interactions with the zero-point field in quantum physics.
How would this reconcile the subjective experience of consciousness with the objective laws of physics, and what implications does it have for our understanding of reality?
J.K.: The zero-point field (ZPF) is a central building block of modern physics, indicating that the vacuum is not a void but, rather, a fluctuating ocean of activity.
In its initial state, the ZPF is a stochastic, unstructured field that carries no information.
My research reveals that the neurophysiological characteristics of conscious processes can be traced back to the resonant interaction of the brain with the all-pervasive ZPF.
As a result of the interaction, the internal structure of the ZPF is modified in such a way that specific field modes (frequencies) are amplified. This insight suggests that the ZPF holds the key to the understanding of consciousness and implies that the ZPF could be more than just an energy field, namely, a psychophysical field that manifests itself extrinsically through its energetic properties, while being intrinsically sentient and phenomenological in nature.
From this perspective, the stochastic initial state of the ZPF can be interpreted as an undifferentiated ocean of consciousness that harbors an enormous range of potentially available phenomenal qualities.
Resonant brain-ZPF interaction causes the amplification of specific ZPF modes, which is inextricably linked with the activation of specific phenomenal qualities and thus with the actualization of differentiated conscious states.
In this theoretical framework, consciousness fits seamlessly into the worldview of physics. More precisely, subjective experiences are reconcilable with the laws of physics since consciousness constitutes the intrinsic nature of the physical and can be regarded as the ultimate realizer of the physical world.
The essential implications for our understanding of reality are as follows:
(1) In the form of the ZPF, there is an infinite reservoir of potential manifestations;
(2) the transition from potentiality to actuality takes place through resonant interaction with the ZPF;
(3) consciousness is the intrinsic driving force behind this manifestation process.
You’ve described the zero-point field not as empty space, but as a structured, information-rich background and, increasingly, we seem to be coming to learn that there’s more to be found between the 1s and 0s of reality.
From your perspective, does this field function like a passive substrate, or does it play a more active role in shaping phenomenological experience—and if so, how?
J.K.: In its initial state, the ZPF is a stochastic, unstructured field that carries no information. Physical systems that interact resonantly with the ZPF cause modifications to the internal structure of the ZPF and enrich the field with information.
This applies particularly to our brains.
Based on the framework outlined above, the information states imprinted on the field can be interpreted as our conscious memory traces.
In this process of information enrichment, the ZPF does not serve as a passive substrate but as a dynamic player involved in the formation of highly synchronized neural activity patterns that are characteristic of our streams of consciousness.
The phenomenal states we experience are shaped by modulating the concentration of most abundant neurotransmitter (glutamate), the primary ZPF coupling molecule in the brain.
In contrast to views where consciousness appears later in cosmic evolution, your work suggests a deep continuity between early-universe physics and organized, conscious systems that can exhibit some kind of aware agency.
Would you say consciousness is a late emergent feature of matter, or a fundamental aspect of the universe - that it’s an aperture of reality’s self-perpetuating creative function?
J.K.: According to the theoretical framework I have developed, consciousness is not a product of biological evolution and, hence, not a cosmic latecomer.
Quite the contrary, consciousness is a fundamental feature of the universe.
In this sense, evolution did not invent a mysterious mechanism that creates consciousness from insentient matter.
Rather, evolution has brought forth increasingly complex biological systems that utilize a universal mechanism, enabling them to form ever more complex phenomenal states through dynamic interaction with an omnipresent field of consciousness.
So, in a way, consciousness becomes locally accessible through biological structures.
You often describe the brain less as a generator of consciousness and more as a selective interface or resonant structure.
What implications does this view have for altered states of consciousness, such as deep meditation, near-death experiences, or psychedelic states?
What does it mean for those who want to, through some means or another, leverage the resonance?
J.K.: In the ZPF-based approach, the brain functions as a resonant oscillator that can selectively couple to a particular range of ZPF modes. This range is determined by the neurotransmitter concentrations in the brain.
In other words, under normal conditions the brain is attuned, and hence restricted, to a limited spectrum of ZPF modes.
Empirical evidence indicates that meditative practices and psychedelics detune the coupling mechanism and remove these restrictions, which has a number of implications.
One of the most striking consequences is that previously generated sequences of ZPF information states cannot be accessed, meaning that self-referential conscious states cannot be formed, leading to ego dissolution and spiritual experiences, such as feelings of profound joy and a sense of oneness with the world.
In several of your papers, you propose that conscious states arise through a resonance-like coupling between the brain and the zero-point field.
How does this resonance differ, in your view, from more traditional emergent or computational models of consciousness?
J.K.: According to conventional neuroscientific models, conscious experiences emerge from or are identical with neural activity patterns.
It is precisely this reduction of consciousness to a neural substrate that leads to well-known explanatory gaps.
The strength of the ZPF-based approach is that it eliminates these explanatory gaps and provides a conclusive explanation for the formation of phenomenal states. The crucial point is that synchronized neural activity patterns should not be regarded as the ultimate basis of consciousness but are to be seen as signatures of a mechanism underlying conscious systems whose roots lie at a deeper level.
This leads to a paradigm shift from a neural substrate of consciousness to a universal substrate of consciousness (the ZPF) that certain physical systems can resonantly interact with via a universal coupling mechanism.
