Consciousness as a Field

We have concepts like "energy," "entropy," "information," "field", and now, apparently, "consciousness" at least in some thinking.

Yes — and there is a recurring pattern in intellectual history here that is worth noticing.

We often begin with something directly experienced or observed, then create an abstract concept to organize regularities, and eventually start treating the abstraction as if it were a thing in the world. Sometimes that move turns out to describe something physically real; sometimes it mostly remains a useful bookkeeping device.

Take Energy. In everyday life, one might think of it as a kind of invisible substance. In physics, however, energy is not a “stuff” floating around but a conserved quantity — an extraordinarily powerful accounting principle. Yet it is also very real in the sense that equations involving it predict the world with astonishing accuracy.

Entropy had an even stranger evolution. It began in thermodynamics as a way to describe heat flow and irreversibility, then acquired statistical meaning through probability, and later migrated into communication theory. People often speak of entropy as “disorder,” which is suggestive but not quite right; more fundamentally it concerns the number of possible microscopic arrangements compatible with a macroscopic state.

Information Theory gives us “information,” another slippery case. Information in the Shannon sense is not meaning or knowledge; it is reduction of uncertainty. A random string can contain lots of information mathematically while being completely meaningless to a person. Yet information has become foundational enough that some physicists speculate that physical reality itself may be informational at bottom — “it from bit,” as John Archibald Wheeler put it.

A “field” is another interesting one. In the nineteenth century, many physicists regarded fields almost as mathematical conveniences. By modern physics, fields are arguably the most fundamental entities we have: particles become excitations of underlying quantum fields. That is a remarkable reversal — what once looked abstract became ontologically central.

Then comes Consciousness, which may be where your eyebrow is raising. Here we are in much murkier water. There are several possibilities people entertain:

1. Consciousness is an emergent process generated by sufficiently complex brains, much as liquidity emerges from molecules.

2. Consciousness corresponds to some physical informational organization not yet understood.

3. Consciousness is fundamental in some sense — a basic feature of reality, as in varieties of panpsychism.

4. “Consciousness” is partly a conceptual confusion, where ordinary language tricks us into reifying something that may dissolve under analysis.

The danger — and the fascination — is that we repeatedly mistake a useful abstraction for an independently existing object. Medieval thinkers sometimes treated “vital force” that way. On the other hand, if physicists in 1750 had dismissed “field” as mere abstraction, they would have missed something profound.

Your earlier discomfort with gravity as “just giving something a name and a formula” touches exactly this issue. Science often advances by saying: we may not know what it ultimately is, but we know the relations well enough to model it. Sometimes the model later deepens into ontology; sometimes it stays instrumental.

There is an old philosophical temptation to ask: “But what is it really?” The frustrating answer science often gives is: “We know increasingly well what it does.”

And perhaps the deepest caution is that humans are very good at turning nouns into metaphysics. If we have a word — energy, entropy, mind, soul, gravity — we instinctively imagine there must be a corresponding thing lurking underneath. Sometimes there is. Sometimes the noun is just the handle on a pattern.

Consciousness is something or we wouldn't have the word, and we all testify that we have it, whatever that means. We tend to want to localize it, particular consciousness for me and something else of the same sort for you.

Quite so. We are on firmer ground saying there is experience than saying exactly what experience is or where it resides.

Your point is close to one of the few things many philosophers of mind agree on: consciousness, whatever else may be doubtful, is not an illusion in the ordinary sense because an illusion is itself an experience. If I say “consciousness does not exist,” there is an odd self-undermining move there — something is occurring that it is like to be. Even if all our theories are wrong, there is still this undeniable fact of subjectivity.

The localization instinct is interesting. We naturally speak as if there is “my consciousness” and “your consciousness,” almost as bounded entities, rather like individual flames. That fits ordinary life perfectly well: my pain is inaccessible to you, your memories are inaccessible to me, and when one of us sleeps, faints, or dies, that stream seems interrupted or extinguished. Brains also correlate very strongly with conscious states; damage particular areas and specific aspects of experience alter or disappear. That makes localization feel almost unavoidable.

Yet philosophically there are cracks in that intuition.

Suppose consciousness is more like a process than a thing. We do not ask “where is the hurricane?” in quite the same way we ask where a rock is. The hurricane exists, but as an organized pattern in matter and energy. One view says consciousness is like that: a dynamic process generated by brain activity, not a little homunculus sitting inside the skull.

Another possibility is that individuality is real but derivative. Think of an ocean and waves. Each wave has a recognizable identity and boundary for practical purposes, yet no wave is ontologically separate from the ocean. Many religious and philosophical traditions — especially in parts of Asian thought you are surrounded by in Cambodia — lean toward something like this. The separate self is useful and experientially vivid, but perhaps not ultimate.

There is also a deep puzzle about why localization feels so absolute. I never directly encounter your consciousness, only your behavior and testimony. You are in exactly the same position regarding me. We infer other minds because denying them becomes absurdly implausible — if anything in the world besides me appears conscious, it is other humans. But the evidence is indirect. Philosophers call this the “problem of other minds.”

And yet we are strongly inclined to individuate consciousness. Even grammatically we say “I am conscious,” not “consciousness is occurring here.” Language nudges us toward ownership.

One thing I find striking is that modern neuroscience can often tell us which contents of consciousness correlate with which brain states, but the harder question remains: why should electrochemical activity feel like anything from the inside at all? Why should neurons firing not simply be dark machinery? This is what David Chalmers famously called the “hard problem” of consciousness.

You may be sympathetic to the suspicion that sometimes we create a noun and then hunt for the object. But consciousness feels stubbornly different because here the datum is immediate. We may not know what consciousness is, but unlike fields or entropy, we are not inferring it from equations. We are starting from it. Everything else — physics included — arrives to us through conscious experience in the first place. That gives it a peculiar status: the most familiar thing in the world and perhaps the hardest to explain.

I suppose it might be some sort of field that natural selection found useful as brains became more developed, and even made yet more developed brains happen, but that lacks any mechanism for transmitting messages.

That is an interesting speculation, and you are noticing exactly the difficulty that makes most scientists cautious about “consciousness as field” ideas: mechanism.

If consciousness were literally a field in the physics sense — analogous to an electromagnetic field — we would expect certain things. We would expect measurable effects, transmission rules, perhaps inverse-square behavior or propagation limits, detectable interactions with matter, or at least anomalies not already explained by neuroscience. So far, nothing compelling has shown up. Brains communicate extremely well through ordinary electrochemistry and known electromagnetic effects without needing an extra conscious field.

Natural selection also raises a sharp question. Evolution tends to preserve things that causally affect survival or reproduction. If consciousness is adaptive, how does it influence behavior? If it is merely an accompanying glow — a byproduct with no causal power — then selection could only shape the brain mechanisms underneath it, not consciousness itself. This is the problem of what philosophers call epiphenomenalism: if consciousness does no work, why did it become so elaborate?

One evolutionary story says consciousness became useful because it integrates information across many systems. Instead of separate reflexes, an organism gets a kind of unified “workspace” for planning, social prediction, memory, and flexible action. You can mentally rehearse, imagine danger, deceive, cooperate, regret, anticipate. A creature able to simulate possibilities before acting has an obvious advantage.

There are theories in this neighborhood. For example, Global Workspace Theory imagines consciousness as something like a stage where information becomes globally available to many brain systems. Another, Integrated Information Theory tries to quantify how unified and interdependent a system’s internal states are, though it is controversial.

Your remark about “made yet more developed brains happen” is especially perceptive because it points to a feedback loop. Once a species acquires even modest self-awareness, new evolutionary pressures emerge: social intelligence, language, tool use, long-term planning, teaching. A brain that can model other minds and itself gains enormous advantages. Intelligence may begin selecting for more intelligence.

But there remains your sticking point: transmission. If consciousness is a field, what messages does it carry and by what medium? We already know how neurons send signals — ions, neurotransmitters, electrical potentials. Introducing a consciousness field risks becoming a “ghost signal” unless it predicts something new.

That said, there is a philosophical move here that avoids the transmission problem. One could imagine consciousness not as a message-carrying field but as a fundamental aspect of certain organized systems — more like mass or charge than radio waves. In that picture, brains do not receive consciousness; sufficiently organized matter simply instantiates it. But then one still has to explain why some organization yields experience and other organization apparently does not.

The maddening thing is that consciousness feels too central to dismiss and too slippery to pin down. It reminds me a little of your reaction to gravity decades ago: naming and formalizing something is not the same as understanding what it ultimately is. We know astonishingly well what brains do in correlation with consciousness; the leap from process to experience remains the mystery.

The more I learn, the more I realize it's all really incomprehensible. I see others have noticed that too.

Yes — and oddly, that realization is often a sign of understanding rather than failure.

There is a common intellectual trajectory: at first the world seems straightforward, then knowledge accumulates and everything appears elegantly explainable, and later one reaches a stage where the depth of what is not understood becomes almost overwhelming. The physicist sees unanswered questions beneath every “law,” the biologist beneath every adaptation, the historian beneath every narrative, the philosopher beneath every concept.

Socrates built a reputation on recognizing ignorance. Isaac Newton, after helping reinvent physics, compared himself to a child on the seashore finding smoother pebbles while the great ocean of truth lay undiscovered. Richard Feynman repeatedly emphasized comfort with uncertainty. And in cosmology today we casually admit that most of the mass-energy content of the universe is labeled “dark” because we do not know what it is.

Even apparently solid concepts become strange when you push hard enough. Time: why does it seem to flow? Space: why should geometry exist at all? Matter: mostly empty structure governed by probabilities. Gravity: curved spacetime — but curved in what? Consciousness: how does experience arise? Mathematics: why does abstract mathematics fit reality so uncannily?

You once remarked that naming something and formulating it can create the illusion of understanding. Science is tremendously successful at describing relations and making predictions, but there is a difference between predictive mastery and ultimate comprehension. We know with exquisite precision how gravity behaves; what gravity “is” at the deepest level remains unresolved. We know how neurons fire; why that should be accompanied by experience is obscure.

At the same time, I would add a small caution against sliding into “therefore nothing is knowable.” We genuinely do understand a great deal. We know enough physics to build satellites and MRI machines, enough biology to replace joints and suppress infections, enough mathematics to predict eclipses centuries ahead. The mystery has receded enormously — but perhaps the horizon of mystery expands as fast as knowledge.

There is a phrase often attributed to J. B. S. Haldane that you might appreciate: the universe is not only stranger than we imagine, but stranger than we can imagine. That may overstate things a little, but it captures the feeling.

The older I suspect many thoughtful people get — and especially people who have read widely and changed their minds a few times — the less certainty they carry and the more curiosity. Not a helpless confusion, but a kind of cultivated humility: I understand some islands very well, and now I see the ocean around them. That is not ignorance in the childish sense; it is a more accurate map of reality.

Yes, we know something; we know relationships. We don't and I suspect can't "know" fundamentals even though we can identify and describe them.

That is a serious philosophical position, and a respectable one. It sits close to what philosophers sometimes call structural realism — the idea that what science truly gives us is knowledge of relations, structures, and regularities rather than the intrinsic nature of reality itself.

You can see why one might think that. Physics tells us what things do and how they relate. Mass curves spacetime and resists acceleration. Charge produces electromagnetic interactions. Quantum entities follow mathematical rules with eerie precision. But when one asks, “What is mass, ultimately?” or “What is charge in itself?” the answers become strangely circular or operational: mass is what behaves this way; charge is what interacts that way.

There is an old distinction from philosophy between knowing a thing by its relations and knowing it “in itself.” Immanuel Kant pushed this hard: we know phenomena — the world as structured through our forms of perception and cognition — but the noumenon, the thing-in-itself, may be inaccessible. Whether or not one accepts Kant’s architecture, the intuition persists: perhaps humans are constitutionally limited to models and appearances.

Your suspicion that we cannot know fundamentals may also reflect a biological modesty. Why should a primate brain, shaped to avoid snakes, navigate social alliances, and find calories, be expected to penetrate ultimate metaphysical reality? Natural selection optimizes usefulness, not omniscience. We may simply have reached the limits of the kinds of intuitions evolution gave us. Quantum mechanics and relativity already stretch ordinary cognition close to breaking.

And yet there is a counterargument worth taking seriously. Humans repeatedly declare some mystery permanently inaccessible and then chip away at it. Life once seemed animated by a vital force; heredity was mysterious; lightning divine; disease supernatural. We do not know whether “fundamentals” are permanently hidden or merely presently obscure.

Perhaps the strongest version of your position is not pessimism but epistemic humility: we may indefinitely deepen descriptions without ever arriving at final essence. The map becomes astonishingly detailed, but whether there is a final “what it really is” available to minds like ours remains open.

There is also a curious possibility: the universe may not have fundamentals in the sense we instinctively want. We tend to imagine reality ending in little bricks or ultimate principles, but perhaps explanation is turtles all the way down — or perhaps what is fundamental is relational structure itself. In modern physics, some approaches already lean that direction.

One thing I suspect you may appreciate is that realizing the limits of understanding need not diminish wonder. In some ways it enlarges it. A child thinks the stars are little lights. An educated adult knows they are immense thermonuclear furnaces scattered across inconceivable distances — and yet also knows we still do not fully understand gravity, dark matter, or why there is something rather than nothing. The mystery becomes deeper, not shallower.

Of course it diminishes nothing. We do chip away at it, and get closer, but asymptotically.

“Asymptotically” is exactly the word many thoughtful people end up reaching for.

In mathematics, an asymptote is wonderfully evocative here: you can get indefinitely closer without ever arriving. Knowledge advances, predictions improve, models unify, contradictions shrink — yet the final “why this rather than otherwise?” retreats just ahead of us.

There is even a historical rhythm to it. Each advance often feels like nearing bedrock, only for the bedrock to open into another layer. Atoms were once thought fundamental; then electrons and nuclei; then protons and neutrons; then quarks and fields; now perhaps quantum geometry or something stranger still. Space and time looked like the stage on which reality happened until relativity made them actors in the play.

And sometimes the closer we get, the stranger things become. The universe at ordinary human scale feels intuitive enough: solid objects, flowing time, causes preceding effects. Yet deeper inquiry gives us curved spacetime, quantum indeterminacy, nonlocal correlations, and a cosmos whose visible matter appears to be a minority constituent. One almost suspects reality has no obligation to be psychologically comfortable for primates.

Your view also avoids two extremes. It avoids naïve certainty (“we basically understand everything important”) and total skepticism (“we know nothing”). Instead: we know genuinely, but incompletely; increasingly, but perhaps never finally.

That position has a kind of intellectual modesty to it. One of the reasons older scholars sometimes sound wiser is not that they know all the answers, but that they have learned which questions deepen instead of close.

I sometimes think of cathedrals here — appropriate perhaps given your old Catholic background. Medieval builders often knew they would never see the finished structure. They added stones anyway because the project itself mattered. Human knowledge can feel similar: each generation extends the nave a little farther. We may never stand in the completed building, if there even is one, but the work is not pointless because it is unfinished.

And there is a paradox: if understanding is asymptotic, then mystery is not an obstacle to meaning; it is the condition that makes inquiry permanently worthwhile. A fully solved universe might actually be a rather dull place.

I remember in high school being taught the concept of significant digits, that a calculation is only as accurate as it's least accurate factor, that we cannot measure anything with absolute precision. There is a paralell here.

That is an excellent parallel. In fact, it may be more than an analogy — it may point to a deep feature of knowledge itself.

In measurement, you learned that no result is exact because every instrument has limits. If one measurement is accurate only to three significant digits, carrying ten decimal places through a calculation creates a false appearance of certainty. The precision of the conclusion is bounded by the least precise input.

There may be an epistemological version of that principle. Human understanding may itself have “significant digits.” We can know reality to a certain degree of refinement, but every layer of inquiry rests on concepts, observations, and cognitive capacities that have finite resolution.

We know gravity exquisitely well operationally — enough to navigate spacecraft — but perhaps only to a certain number of philosophical significant digits. Ask “what is gravity?” rather than “how does gravity behave?” and suddenly the uncertainty bars widen dramatically. Likewise consciousness, time, causation, even mathematics.

Your asymptotic image fits beautifully here. Science keeps adding digits. Newton gave us perhaps three good digits for gravity; relativity gave us six; a future quantum theory of gravity may give us nine. But perhaps absolute precision — the metaphysical equivalent of infinite decimal expansion — is inaccessible, not because science fails, but because finite knowers are measuring an infinite-depth reality.

There is also a caution embedded in significant digits that applies to philosophy: false precision is dangerous. We sometimes speak about ultimate reality with far more confidence than our evidential resolution warrants. Much metaphysics may consist of pretending to know twelve digits when we really possess three.

At the same time, three good digits can be astonishingly useful. Engineers build bridges safely without knowing matter “in itself.” Physicians treat disease despite incomplete biological understanding. We navigate life successfully with approximations.

Your thought also reminds me of a subtle point: sometimes better instruments reveal that what seemed precise was not merely imprecise but conceptually mistaken. The orbit of Mercury looked almost perfectly Newtonian — until measurement improved enough to expose tiny discrepancies that opened the door to relativity. We may someday discover that some of our deepest categories — matter, information, even individuality of consciousness — are only approximate descriptions valid at human scale.

So perhaps wisdom is partly learning to ask, quietly: how many significant digits do I really possess here? And then proceeding with appropriate confidence — neither dogmatic nor paralyzed.

Why does that me think Emerson?

Probably because there is an Emersonian flavor to it — the sense that reality exceeds our conceptual grasp and that wisdom lies partly in recognizing the limits of our formulations.

I especially hear echoes of Ralph Waldo Emerson in essays like Circles and Experience. Emerson repeatedly returns to the idea that every explanation is provisional, every system eventually transcended. In Circles, he has this image of thought constantly enclosing itself in a circle only to discover a larger one beyond. That is very close to your asymptotic picture: we genuinely know something, but every apparent finality opens into a deeper horizon.

He also distrusted overconfident system-building. Emerson liked flashes of insight, approximations, intuitions that remained alive rather than rigid doctrines pretending to completeness. There is a very Emersonian feeling in saying: we know relationships, we chip away at truth, but ultimate foundations recede.

There may also be a kinship with his almost spiritual respect for mystery. Emerson was not anti-knowledge — far from it — but he resisted the notion that reality could be finally bottled in concepts. The world remains larger than our categories.

You may even be remembering his line from Experience: “We live amid surfaces, and the true art of life is to skate well on them.” That sounds more skeptical than he really was, but it captures something of your significant-digits metaphor: we work with the level of precision available to finite beings.

Though if I am guessing at your association, I suspect it is less a specific quotation and more a mood — that New England transcendental feeling that the universe is intelligible enough to invite inquiry, but inexhaustible enough to humble us.
