title: "What Really Lies Behind Physical Reality"
slug: material-world-user-interface-hoffman
summary: "Our conscious experience presents a vivid material world that feels like direct access to reality — yet perception is actively constructed, species-specific, and shaped for action rather than truth. As neuroscience, physics, and AI converge on harder questions about mind and matter, a compelling picture is emerging that we can gravitate toward: the material world as an evolved interface, with networks of consciousness behind it. This piece offers a potential mindful lens on religion and spirituality — honoring what traditions point toward while reading their symbols more carefully — and explores Hoffman's geometry of conscious agents, including obelisk-like structures that may rhyme with sacred forms humans have raised for millennia."

Right now, as you read these words, something is happening that is easy to overlook because it feels so ordinary. There is a field of color and form arranged in space. There may be ambient sounds, the subtle pressure and temperature against your skin, a faint sense of your posture, perhaps the lingering taste of something you ate earlier or the smell of the room. Thoughts and feelings arise and pass. Most of all, there is a background conviction that all of this is taking place inside a larger, stable, objective reality that exists whether or not you are paying attention to it.

This is the default texture of conscious experience for most human beings most of the time. It does not present itself as a model or a guess. It presents itself as the world itself. We do not normally feel that we are inside an experience; we feel that we are in the world and that experience is simply the way the world shows up for us.

Yet the more closely we examine this presentation, the more it reveals itself as something actively made rather than simply received.

And something interesting happens when you hold that insight alongside where science and technology are heading. Neuroscience is mapping prediction and construction in the brain with increasing precision. Physics is quietly questioning whether spacetime is fundamental. Artificial intelligence is forcing us to ask what consciousness is and what it is for. These threads do not yet add up to a settled consensus — but they are converging on a picture that feels less like a fringe departure and more like a direction humanity can gravitate toward: one in which the vivid material world is not the deepest layer of reality, but a useful interface shaped for creatures like us.

For many readers, that trajectory also reaches toward territory the great religions have circled for millennia — but with a sharper, more mindful lens. Not a supernatural figure behind the clouds, but something that may look more like consciousness itself, organized at scales we are only beginning to imagine.

This article follows that path from the inside out. It begins with what conscious experience actually feels like, and moves toward one rigorous account of what may lie behind the appearances we inhabit — not as a demand to believe, but as a potential way of viewing religion and spirituality with greater mindfulness: attentive to the symbols, curious about what they point toward, and free of both naive literalism and flat dismissal.

::::section{title="The Constructed Nature of Experience" id="the-constructed-nature-of-experience"}
:::brief
Consider vision, the sense most of us rely on most heavily. Photons strike the retina, are converted into electrochemical signals, and travel through multiple stages of processing in the brain before anything like a visual scene appears in experience. At no point do you have direct contact with the light or the objects from which it reflected. What you have is the result of an enormous amount of neural computation that includes filling in missing information, applying expectations from past experience, and suppressing signals that the brain deems irrelevant.
:::

This active construction is visible in everyday illusions. The famous dress photograph that appears blue and black to some people and white and gold to others is not merely a matter of ambiguous lighting. It demonstrates that your visual system is making an unconscious assumption about the color of the light source and then adjusting the perceived colors of the dress accordingly. Change blindness studies show that people can fail to notice major alterations in a visual scene when those alterations coincide with a brief visual interruption such as a blink or a cut in a video. The hollow mask illusion makes a concave mask appear convex because the brain applies its strong prior expectation that faces are convex. Even the simple fact that each of your eyes has a blind spot where the optic nerve leaves the retina, yet you perceive no hole in the visual field, shows constant neural completion.

![The constructed nature of perception](https://mystrangemind-images.us-iad-10.linodeobjects.com/images/articles/material-world-user-interface-hoffman/01-constructed-perception.jpg)

These phenomena are not malfunctions. They are features of a system that is always predicting, editing, and completing. Predictive processing theories in neuroscience describe the brain as a prediction machine that generates expectations about incoming sensory data and updates its model when prediction errors occur. What reaches conscious experience is already heavily filtered and interpreted. The feeling of direct, unmediated contact with reality is itself part of the construction.

The same constructive activity appears in other senses. Auditory experience fills in missing phonemes in speech and creates the illusion of continuous sound from discrete pressure waves. Touch and proprioception combine to produce the sense of a coherent body in space, a sense that can be experimentally shifted or extended as in the rubber hand illusion or full body illusions induced in virtual reality. Even the experience of time is constructed; the brain stitches together successive moments and can dilate or compress subjective duration depending on attention, emotion, and context.

::::section{title="Different Worlds, Different Experiences" id="different-worlds-different-experiences"}
:::brief
If experience is constructed, then the particular construction any creature inhabits depends on its sensory apparatus, its evolutionary history, and its needs. The world as experienced by a human is only one version among many possible versions.
:::

A tick crawling on skin responds primarily to the chemical butyric acid and to warmth. Its experiential world is radically simpler than ours and centered on those two features. A bat navigating at night builds a detailed spatial model from returning echoes of its own ultrasonic pulses. The spatial world it experiences is acoustic rather than visual. Many birds can sense the Earth’s magnetic field and use it for navigation; their experience of direction includes information unavailable to us without instruments. The mantis shrimp possesses up to sixteen distinct types of photoreceptor and can detect circularly polarized light and an enormous range of colors. What counts as a vivid color for us is only a small slice of what is available in its experience.

![Different creatures, different experiential worlds](https://mystrangemind-images.us-iad-10.linodeobjects.com/images/articles/material-world-user-interface-hoffman/02-different-worlds.jpg)

Within our own species the range is also wider than we usually assume. People with synesthesia experience consistent cross-modal associations, such as numbers appearing in specific colors or sounds having spatial locations and textures. Individuals with aphantasia report no voluntary visual imagery at all; their inner experience lacks the pictures most of us take for granted. On the autism spectrum, sensory sensitivities can make certain sounds, lights, or textures overwhelmingly present or strangely muted. Psychedelic substances and certain meditation practices can temporarily alter the filtering and binding processes that normally produce a stable, coherent world, revealing how much of ordinary experience depends on those processes remaining in their default configuration.

These variations are not merely interesting curiosities. They demonstrate that what we call the world is always the world-as-experienced-by-some-particular-kind-of-experiencer. There is no single, neutral, observer-independent presentation that all conscious beings share. Each interface is tuned to the needs and capacities of the organism that evolved it.

::::section{title="Why Does Anything Appear at All?" id="why-does-anything-appear-at-all"}
:::brief
Even after acknowledging that experience is constructed and species-specific, a more basic question remains. Why is there experience with subjective qualities in the first place? Why does any of the neural activity in a brain or the interaction among conscious systems result in something that feels like anything from the inside?
:::

When you see the color red, there is not only information about wavelength being processed. There is the specific, ineffable quality of redness itself. The same is true for the particular texture of a pain, the taste of coffee, the feeling of recognizing a friend’s voice, or the warmth of sunlight on skin. These qualities, often called qualia, are not additional facts that can be read off from the physical description of the system. They are what it is like for the system to be undergoing that process.

![The subjective quality of experience](https://mystrangemind-images.us-iad-10.linodeobjects.com/images/articles/material-world-user-interface-hoffman/03-subjective-qualia.jpg)

This is sometimes called the hard problem of consciousness because it is not solved by explaining the functions that experience serves or the neural correlates that accompany it. We can understand how the brain processes color information, how it generates expectations, and how it produces reports about color. Yet none of that automatically explains why there should be a felt redness rather than merely colorless information processing that happens to result in verbal behavior about red things.

The mystery deepens when we notice how unified and coherent experience usually feels despite being supported by widely distributed brain processes. The binding problem asks how features processed in different cortical areas, colors here, shapes there, motion elsewhere, come together into a single, apparently seamless scene. Dreams show that rich, spatially extended, emotionally charged experience can occur with minimal or altered sensory input from the external environment. In certain neurological conditions, patients can lose specific qualities of experience, such as the ability to recognize faces or to experience color, while other aspects remain intact. These dissociations suggest that the various dimensions of experience can be selectively present or absent.

The fact that anything appears with felt qualities at all is the most intimate and yet the most scientifically elusive feature of conscious experience. It is the feature that makes the world not merely a set of processes but something that matters from the inside.
::::

::::section{title="Taking the Features of Experience Seriously" id="taking-the-features-of-experience-seriously"}
:::brief
The characteristics we have been examining, the active construction and editing of perception, the radical differences in experiential worlds across species and individuals, the persistent sense that the world is external and objective even while being constantly generated, and the presence of subjective qualities that resist reduction to physical description, together form a substantial body of data about conscious experience.
:::

One common response is to assume that these features will eventually be explained as byproducts or functions of an underlying material reality that exists independently of any experiencer. On this view, the brain somehow produces consciousness as an emergent property, and once we understand the brain sufficiently we will understand why experience has the character it does.

![The materialist default overlooks lived experience](https://mystrangemind-images.us-iad-10.linodeobjects.com/images/articles/material-world-user-interface-hoffman/06-materialist-misses-experience.jpg)

An alternative is to treat the features of conscious experience as primary data that any adequate account of reality must accommodate rather than explain away. If experience is always constructed, always from a particular perspective, and always includes subjective qualities that are not obviously present in the physical description of the system, then perhaps the material world that appears in experience is not the most fundamental layer of reality. Perhaps it is better understood as a presentation shaped by the needs and capacities of experiencing systems — and perhaps that understanding is not a retreat from science but a trajectory science itself may be drifting toward.

Evolutionary biology supplies additional pressure in this direction. Natural selection favors traits that increase the probability of survival and reproduction. There is no requirement that those traits produce accurate representations of an objective environment. In many circumstances a simplified or even systematically distorted presentation can guide adaptive behavior more effectively than a veridical one. The organism that responds quickly to useful patterns in its niche can outperform the organism that attempts to track every detail of an independent reality. This does not prove that our experience is non-veridical, but it removes the assumption that evolution would have equipped us with perceptions that reliably mirror the way things are in themselves.

::::section{title="A Framework That Takes Experience as Primary" id="a-framework-that-takes-experience-as-primary"}
:::brief
Donald Hoffman has developed a detailed theoretical response that begins from these observations about conscious experience and follows them rigorously. Rather than starting with the assumption that physical processes in the brain give rise to consciousness, his approach treats conscious experience as fundamental and develops mathematical models of what kind of reality could produce the specific patterns we observe in perception across species.
:::

In this framework the material world of everyday experience, including space, time, and physical objects, functions as an interface. The interface is shaped by natural selection to guide adaptive behavior within a particular niche. It is useful precisely because it hides most of the complexity of whatever exists independently of the experiencer and presents only the information and distinctions that matter for survival and reproduction. The desktop metaphor is helpful here. The icons on a computer screen allow a user to perform complex operations without needing to understand or directly manipulate the underlying hardware and software. The icons do not resemble the actual transistors or code, yet they enable effective interaction. Similarly, the colors, shapes, sounds, and solid objects of perceptual experience enable effective action even while bearing little resemblance to the objective reality that supports them.

![The material world as interface](https://mystrangemind-images.us-iad-10.linodeobjects.com/images/articles/material-world-user-interface-hoffman/04-interface-theory.jpg)

Hoffman’s evolutionary game theory simulations support this view. In simplified models of resource competition, perceptual strategies that tracked objective truth were routinely outcompeted by strategies that tracked fitness payoffs alone. Veridical perception was driven to extinction in most environments because it carried higher computational costs without corresponding gains in survival and reproduction. Only under very special conditions, where fitness happened to align closely with objective structure, did truth-tracking strategies persist. In general, the simulations suggest that natural selection favors interfaces tuned to utility rather than to accuracy.

::::section{title="What Might Lie Behind the Interface" id="what-might-lie-behind-the-interface"}
:::brief
If experience is an interface, what lies behind it? Hoffman proposes networks of conscious agents whose fusion produces high-dimensional geometries — including obelisk-like forms that point beyond spacetime. The rhyme with sacred vertical structures across religions is striking, even if ancient builders knew nothing of the math.
:::

This reverses the usual direction of explanation. Instead of consciousness emerging from complex arrangements of unconscious matter, matter and spacetime appear within the interfaces generated by interacting conscious agents. The agents themselves are not located inside spacetime; spacetime is one of the interfaces they employ. Recent extensions of the framework explore how networks of agents can fuse into higher-order unities whose experiential scope transcends what any single agent could encompass. In mathematical models using Markov kernels to describe transitions between experiential states, fusion corresponds to combining kernels along particular lines, producing new geometric structures in high-dimensional spaces. These structures may be more fundamental than the low-dimensional interface of spacetime and matter that we inhabit.

![Networks of conscious agents beyond the interface](https://mystrangemind-images.us-iad-10.linodeobjects.com/images/articles/material-world-user-interface-hoffman/05-conscious-agents.jpg)

In Hoffman's recent work, some of these fused structures take forms he and collaborators describe as obelisk-like: tapering geometric objects that narrow toward a point, encoding relationships among conscious agents without being contained within ordinary space and time. They are not stone monuments, but mathematical ones — invariants and symmetries that stand outside the spacetime desktop. Whether or not the physics ultimately bears them out, the shape is suggestive. An obelisk points. It draws attention from a broad base toward a singularity above the frame.

That gesture has appeared in religion again and again. Egyptian obelisks at Heliopolis were aligned with the sun and raised as petrified rays of light, connecting earth to the divine. Ethiopian stelae, Hindu lingams, Buddhist stupas, mosque minarets, and Gothic spires all repeat a related grammar: the vertical axis, the ascent, the meeting of ground and sky. No one is obliged to believe that ancient builders understood Markov kernels or high-dimensional fusion. But it is not absurd to wonder whether some traditions preserved, in stone and ritual, an intuition the mathematics is now approaching from another direction — that reality has a geometry beyond the visible, and that the sacred is often marked by forms which point toward it.

Viewed mindfully, an obelisk or steeple need not be read only as tribal mythology or mere architecture. It can be held as a question made visible: what lies above and beyond the interface? The symbol and the equation may be different dialects of the same reach.

Religious traditions across history have also pointed toward unity beyond the individual self — a ground of being, a universal mind, a divine presence saturating reality. Hoffman does not frame his work as theology, and conscious agents are defined in precise mathematical terms. Yet the structural rhyme is difficult to ignore. If fused networks of experiencing systems can generate spacetime and matter as shared interfaces, then the oldest spiritual intuitions may have been groping toward real architecture, translated through the only metaphors their eras possessed. The prophets and mystics may not have been merely inventing stories. They may have been sensing, through the fog of their interface, that consciousness runs deeper than the furniture of the world.

The difference is that a mindful future understanding would not ask for belief in the mythic desktop — the anthropomorphic God, the fixed cosmology, the tribal boundaries drawn around the sacred. It would ask whether the deeper layer those myths indicated can finally be approached with rigor and contemplative attention. What humanity has named God might turn out to be nothing like a person on a throne. It might be closer to the living depth of experience itself: vast fused agencies of consciousness, or the whole networked field of mind from which our shared physical presentation arises.

The framework also connects with broader questions in physics and mathematics. Efforts to unify quantum mechanics and gravity have led some physicists to suggest that spacetime is not fundamental but emergent. Hoffman’s approach supplies an evolutionary and experiential grounding for that suggestion. It also raises the possibility that mathematics, which describes the interface with such precision, may be revealing something about the deeper architecture of conscious interaction rather than merely describing patterns within the interface itself. Universal mathematical features such as prime numbers could function as potential common signals across different interfaces, much as they have been proposed in the search for extraterrestrial intelligence.

None of this claims to have mapped the full territory beyond the interface. The models remain partial and open to refinement. What the framework does provide is a coherent way to take the constructed, species-specific, and qualitative character of conscious experience as primary rather than as something to be explained away by an assumed material substrate — and, perhaps, a way to honor what religion was reaching for without remaining trapped inside its ancient user interface.

::::section{title="Gravitating Toward a Deeper Understanding" id="gravitating-toward-a-deeper-understanding" era="2026–2040"}
:::brief
At minimum, this framework offers a potential way of viewing religion and spirituality from a more mindful perspective — holding symbols lightly, attending to what they point toward, and refusing both naive literalism and dismissive materialism. It may also open toward a next-generation spirituality that finally knows what it is reaching for.
:::

The vivid, solid, external reality we inhabit remains the indispensable setting in which we act, suffer, love, and create. At the same time it appears as a particular interface shaped by evolutionary history and by the needs of the kind of conscious agents we are. That is not a reason to dismiss it. It is a reason to take it seriously on its own terms while remaining open to what may lie beneath.

![Mindful attention before sacred vertical forms](https://mystrangemind-images.us-iad-10.linodeobjects.com/images/articles/material-world-user-interface-hoffman/07-mindful-obelisk-spire.jpg)

This reorientation has practical consequences. It encourages humility about the completeness of any scientific description that remains entirely within the interface. It also encourages respect for the interface itself. Just as one must take desktop icons seriously when using a computer, we must take the appearances of space, time, objects, and other beings seriously if we wish to navigate our situation effectively. The interface is not arbitrary; it is highly tuned.

At the same time, the reorientation keeps open a future that feels increasingly within reach rather than locked in the distant past of philosophy alone. If conscious agents and their interactions are more fundamental than spacetime, then questions about the unity of consciousness, the nature of individual identity, and what happens when the interface we call a body ceases to function take on new dimensions. Fusion of agents across what appears as vast separation in space or time becomes conceivable. The boundary between self and other may be less absolute within the deeper architecture than it appears within our interface.

None of this requires rejecting the methods or findings of the natural sciences. It suggests that those sciences may be discovering the operating rules of a particular interface rather than the ground of being itself. As virtual reality, brain-computer interfaces, and artificial minds make the constructed character of experience harder to ignore, the case for looking past the desktop grows stronger — not as a sudden conversion, but as a slow gravitational pull toward a deeper picture.

For many people, the most immediate value of this framework may be simpler than a full metaphysical conversion. It offers, at minimum, a more mindful way of relating to religion and spirituality. You do not have to leave your tradition to use the lens. You can stand inside it with greater attention: noticing how ritual, art, architecture, and story function as interfaces within the interface; asking what a symbol is for rather than whether it is literally true; feeling the vertical pull of an obelisk or a spire not as superstition but as a human gesture toward depth. Mindfulness, in this sense, is not vagueness. It is disciplined curiosity about what experience is doing when it presents the world as solid, sacred, or divine.

The great religions of the ancient world were not foolish. They were, in their own way, responses to the same intuition this article begins with: that the visible world is not the whole story, that consciousness matters, that self, death, and what lies beyond the self are not trivial questions. But they spoke through the interfaces available to their cultures — myth, ritual, authority, anthropomorphic gods shaped to fit human social cognition. They were desktop icons pointing at something the desktop itself could not display.

A next-generation spirituality may not need to reject that inheritance. It may need to outgrow its literalism while learning from its mindfulness — the capacity religions often cultivate to attend to presence, suffering, gratitude, and mystery. If networks of conscious agents are more fundamental than matter, then what humanity has called God may not be a bearded patriarch in the sky but something closer to the living field of experience and relation from which our interface-world arises — perhaps vast fused agencies of consciousness, perhaps the whole networked depth of mind itself. That is a conception of the divine that is stranger, more abstract, and in some ways more demanding than the ancient stories. It is also one that can sit alongside neuroscience and physics without asking you to check your reason at the door.

Whether this crystallizes into new forms of practice, community, or ritual remains to be seen. But the gravitational pull is already visible: away from materialism that leaves no room for the interior life, and away from dogma that freezes mystery into fixed images. Toward a spirituality that treats conscious experience as sacred data, takes the interface seriously while refusing to mistake it for the ground, and dares to ask what a mature relationship with whatever lies behind the world might look like in the century ahead.

The mystery of what really lies behind physical reality is not eliminated by this perspective. It is given a different shape, a different set of tools for exploration, and a sense of direction. We may be moving toward an understanding that treats consciousness not as a late accident of matter, but as the terrain from which matter, space, and time first appear — and toward a way of holding the sacred that is at once more ancient and more clear-eyed than before. That is a future worth leaning into.
