In an experiential sense, we each inhabit our own private world. That’s not denying a shared external world or that we can’t have deep relationships with others. But think of something we all know without doubt: I can’t experience your pain. You could be in agony and I’ll feel distress because you’re suffering, but I’m feeling my distress, not your pain. Our experiences are private, separated from the world by a screen that limits our interactions.
This creates a puzzle. If reality is a single field of consciousness, we’d expect to have access to each other’s experiences. Instead we find private individuals locked behind their own sealed points of view. But if we’re both part of one field, why can’t we cross it? Philosophy calls this the decombination problem: explaining how a unified conscious field divides into distinct individuals.
The problem has three aspects:
• Subjectivity: if the field is one subject, how does it become many?
• The boundary: What is the screen between us and what makes an experience mine or yours rather than just something occurring in a field?
• Privacy: If we share an underlying field, why are our experiences isolated?
Let’s start with subjectivity. A subject is a singular point of view: all of our experiences come in one unified perspective. Philosophers call this the unity of consciousness. If the field itself is a unity of consciousness and also a subject, how does one subject become many subjects when a point of view seems indivisible?
Imagine it was possible to divide your brain and transplant each half into a different body. Each one is now a single individual looking out through a different set of eyes. We can’t say which body would be the real you, because a point of view isn’t a physical substance we can cut into parts and divide down to atoms. Half a perspective doesn’t look like anything.
So the puzzle isn’t just that we’re sealed off from each other, but also what’s sealed in. What is this unique perspective on the world that persists through every change in your life?
Subjectivity: why a point of view can’t be cut in half
The first part of the puzzle is how one field can become many points of view. Think about what it’s like to be an individual with a singular point of view on the world. This is what we all experience as “me”. The contents of your experiences change constantly. As a child you played with soft toys and cried when things didn’t go your way. Sensations that were once new and exciting are now mundane. Your thoughts, moods and even your personality are always shifting.
But the point of view, the unique perspective to which those experiences appear, remains constant. The world moves around it while you hold still. If everything changes, what is it that stays the same? And if you’re made entirely of a conscious field, how can there be a stable, persisting you at all?
We can picture this with a swing. Once you’re swinging, the scenery keeps changing: the ground and the sky rise and fall in front of you. But your point of view stays constant because you’re looking out from the same place. A confined wave does the same thing. It settles into a stable pattern while the field around it keeps moving. That’s called a standing wave.
On this view, an individual subject is like a standing wave in the conscious field. You’re made entirely of the field’s activity, but you’re a stable, persisting pattern within it. The contents of your experiences are the changing scenery and your point of view is the person looking out, the stable pattern that holds while the scenery changes. And a stable pattern within a conscious field is a finite point of view with its own unique set of experiences.
Don’t patterns dissolve?
It’s tempting to picture a subject as a ripple on a pond, but a confined wave isn’t a passing ripple. The patterns it can take depend on the structure of the medium. White light contains every colour. A prism doesn’t create the spectrum, it reveals the colours latent in the unity of the white light. The distinct frequencies are modes, patterns the light always contained.
The same principle applies to individual subjects. Each individual consciousness is a mode of the field: a pattern the field’s structure makes available and expresses under the right conditions, rather than something thrown up by chance. That’s why a subject doesn’t dissolve the way a ripple does. Individuality was always latent in the field, like a colour in white light.
And no two patterns are alike. Each colour has its own unique frequency. Purple isn’t blue. In the same way, each individual subject isn’t interchangeable with any other; we’re each a unique pattern of movement in the spectrum of consciousness.
Does a pattern divide the field?
A dynamic field is pure activity, not a static object made of pieces. Movement can differentiate into patterns without the underlying medium being divided. White light moving through a prism becomes a full spectrum of colours without anything being divided. Each colour is still light, and the light loses nothing by making the distinct colours visible.
A confined wave doesn’t mean located at a position in space, it means held within the field’s dynamics. A hue is distinguished by its frequency, not its location. The individual subjects differ the same way. We’re distinguished by our pattern within the structure, not by being distinct objects at different locations.
This is what the divided brain puzzle was really asking. It only seems unanswerable if the subject is an object in your brain we could cut and divide. But a subject was never an object, it’s a pattern the field expresses. This retains unity: there is one field. But purple isn’t blue and so difference is present within unity. Unity in difference can sound like a contradiction, but it’s what patterns in a field are like.
This answers the first part of our problem. A subject is one indivisible point of view because it’s a stable pattern, not a divisible thing. The next question is the boundary: what separates one pattern from another, and what makes an experience mine or yours rather than just something occurring in a field?
The boundary: what separates one pattern from another
What makes you unique is your particular pattern within the field. The field is dynamic, so each individual pattern is distinguished from the others by how constrained its movement is. That degree of constraint is density.
When we talk about density in a field we picture material density: more stuff in less space. Rocks are dense and air as diffuse. But a dynamic field has no stuff to be thicker or thinner, so density can’t mean a quantity of stuff. It must describe the activity of the field, how it’s moving.
Constrained movement sounds abstract, but we’re all familiar with what that feels like. Constraining movement slows it. Your consciousness slows down when you fall asleep. You go from alert to drowsy, and eventually your consciousness is inactive, sometimes dreaming but sometimes in deep sleep. When you wake up, sometimes you’re still groggy and dull and it takes a while to achieve full acuity. Ordinary language describes the same idea: we call someone quick if they’re intelligent and dense if they’re slow to understand.
Sleep shows this slowing from the inside, what it feels like when our own luminosity dims. So density, in this sense, is tempo: the rhythm of the field’s movement within a pattern.
Can movement slow down without anything being lost?
If density is really just constrained movement and not a quantity of stuff, then light, slowed far enough, should be able to stop without being destroyed and its pattern stays intact. There’s a physics experiment that fits this picture.
We’ve all seen light slow down. A stick placed in water appears to bend at the surface because light slows as it enters a denser medium. The slowing isn’t caused by a loss of energy but by the interference patterns of the light waves. The density is a slowing or change of rhythm of the waves. Pushed to its limit, that same slowing can bring light to a complete stop. In 1999, Harvard physicist Lene Hau and her team slowed a light beam to around the pace of a bicycle. Two years later they stopped a light beam completely.
They did this by sending a light beam into a super-cold cloud of atoms and holding it there. The light wasn’t destroyed or dissipated into the cloud; its pattern was imprinted into the medium like a fingerprint suspended in ice, with the information it carried intact. Then the same light beam was revived and sent on its way. Light was frozen, held in suspended animation, and then reanimated.
This gives us a picture of what happens when light’s movement is constrained. The light beam no longer shines, but its pattern is fully preserved, ready to be released. Hau’s experiment shows that luminosity can be extinguished entirely without the pattern being lost.
You know this from experience too. You forget yourself in deep sleep but the pattern doesn’t dissolve. You’re the same person when you wake up. The luminosity dims but the structure remains. It’s that same structure, the particular degree and pattern of constraint that makes you unique and also screens you from everything else in the field.
Where does one pattern end and another begin?
The reason we intuitively think we should share experiences if we’re in a unified field is because we’re thinking in terms of substance, not dynamics. When we picture a substance, we think of a boundary as a solid wall that surrounds our pattern. But in a dynamic field the boundary is a line where the tempo changes. The pattern is a region of different density, with a distinct tempo and a slower rhythm than the surrounding field. That density variation just is the boundary, the margin where the rhythm of the pattern meets the rhythm of the field. This is the screen between us.
What does a boundary like that do?
Nature already shows us. When light meets a boundary of increased density, some of the light can be reflected back. When the light from the denser region hits the boundary at a shallow angle, it’s reflected back completely. This is total internal reflection and it’s how an optical fibre works. Light travels inside the fibre and the outer cladding is a lower density than the core of the fibre, so the light is reflected inward. This density boundary traps the light inside the cable.
If we apply this idea to our conscious field: the consciousness of an individual subject circulates within its boundary and is reflected inward by the boundary its own pattern creates. The pattern has an increased density, a slower movement. That difference in tempo between the individual’s pattern and the tempo of the field creates the density boundary that makes the subject a private individual, distinct from the field.
Privacy: why your experiences stay yours
The last part of the puzzle is if we share one field why can’t we feel each other’s experiences?
An optical fibre looks dark from the outside even though light is running through it. In the same way, an individual subject is luminous and conscious inside, but dark from the outside. Your consciousness can’t be directly seen by others. This also shows what makes an experience yours: the same boundary that seals a perspective off also means it belongs to a subject, not to the field.
Why are individuality and privacy the same fact?
The boundary that makes an individual perspective is the same boundary that creates privacy. The question of why there are individuals and the question of why individual experiences are private are the same question. A perspective with access to every other point of view wouldn’t be a point of view, it would just be the field. Being screened from everyone else is what it means to be an individual. Seen from the inside, the boundary is a subjective point of view. Seen from the outside, the same boundary is privacy. Individuality and privacy are one fact.
So now the puzzle is answered in three parts:
• Subjectivity: a subject is a stable pattern in the field, not a divisible thing, so one field can hold many points of view.
• The boundary: the edge of a pattern is where its tempo changes, and that edge is what makes an experience yours.
• Privacy: the same edge screens your experience from everyone else, because being screened is what it means to be an individual.
Does this mean we’re completely isolated?
Talking about screens and boundaries makes it sound like we’re totally isolated, but this isn’t a static field with solid walls. The boundary doesn’t cut you off from the field, it defines you within it. We can’t read minds or experience another person’s pain or joy directly, but the effects we produce do travel. We’re patterns within a field, so our activity changes the field. Waves propagate from our movements, our words and our behaviour. These effects cross the boundary, but the inner luminosity doesn’t. I receive the impact of your waves, but not your experience.
While experiences are private, we can still connect with others through the shared medium we both inhabit. If we strike a tuning fork an identical fork also makes a sound. The forks are separated but the vibration travels through the shared medium and the attuned fork responds. We know others by interpreting their exterior. Their words and body language are waves they send across the field. Empathy and sympathy are resonance, not access. We feel with others, never as them. Ordinary language echoes this, we say we resonate with someone, or we’re on their wavelength. The separation is real, but so is the resonance. They’re both features of the same structure.
