Streams of Unconsciousness

When I am … completely myself, entirely alone … or during the night when I cannot sleep, it is on such occasions that my ideas flow best and most abundantly. Whence and how these ideas come I know not, nor can I force them. — Wolfgang Amadeus Mozart

I remember the moment with clarity.

I was riding my bike, thinking of nothing in particular, when the clear and obvious solution to a calculus problem I had flubbed on a university exam a few weeks earlier popped into my head.

We have lots of ways of describing such light-bulb moments: That’s when it finally hit me. The penny dropped. I saw the light. Eureka! My first reaction upon being stopped in my tracks was to swear and expostulate: “A fat lot of good that does me now.”

The second was to marvel at how, when we’re not paying attention, our unconscious minds are busy arranging and rearranging information — mulling strategies and turning over perspectives like deft fingers manipulating a Rubik’s Cube — until a novel idea or a solution to a thorny problem breaks on through to the other side: conscious awareness.

Friends indicate they’ve experienced similar epiphanies, though of course their sudden insights were tailored to their different circumstances.

Usually it’s an “Oh crap, I left the oven on” sort of moment along the lines of what The Meaning of Liff authors Douglas Adams and John Lloyd referred to as an “Ely” — that first, tiniest inkling you get that something, somewhere, has gone terribly wrong. Sometimes it’s a significant but heretofore hidden insight about their lives.

Bottom line: There is a particular species of revelation that arrives not with a trumpet overture after five hours of heavy slogging, but with the faintly accusatory chime of a microwave finishing someone else’s leftovers.

The light-bulb moment does not knock. It does not clear its throat. It materializes while you are flossing, or tying your shoes, or staring at the damp, existentially exhausted plastic carton of arugula in the back of the refrigerator. And it says: By the way, here is the thing you could not think of when it would have been academically or socially or professionally remunerative to do so.

Every onetime grad student from half a century ago still shudders at the memory of something like this:

Two weeks after looking like a fool in front of your prof and your peers — having confidently used the word “mitosis” to mean either a Greek island or a minor character in the Peloponnesian War —the correct answers float up through sleep like a scuba diver tapping your ankle. You sit upright in bed, incandescent with belated mastery, whispering “Mykonos” or “Lamachus” to no one, because the only witness is a spider plant in the dark that already doubts your competence.

Such a revelation is total, self-certifying. It has the emotional texture of having always known the thing, of having briefly misplaced it behind the mental couch.

A trivial form of this phenomenon — so long as no conscious effort is put into it — is what James Joyce called the “afterwit” in Ulysses: coming up with a perfect reply or a clever retort when it’s too late to deliver it. Even among anglophones, the French description of trenchant but tardy staircase wit (derived from an essay written in the 1770s by the great encyclopedist Denis Diderot) is more commonly used: “l’esprit de l’escalier.”

The best-known pop-cultural apotheosis of an endowment from the unconscious, meanwhile, is the morning when Paul McCartney woke with “Yesterday” fully formed in his head, as if some benevolent nocturnal intern had slipped a demo under the door.

The melody was so complete, so suspiciously gift-wrapped, that he reportedly spent weeks asking people whether he had subconsciously plagiarized it from the collective jukebox.

This is the other feature of such revelations: their air of illicitness, as though one has sneaked into the kitchen at 3 a.m. and found a finished apple pie cooling on the counter with a note that says DON’T ASK. (On the other hand, George Harrison could have spared himself a copyright infringement lawsuit over “My Sweet Lord” a few years later if he had canvassed others on whether the melody reminded anyone of the Ronnie Mack song, “He’s So Fine.” If you’re not careful, what seemed to manifest itself as an ingenious gift from the gods can turn out to be 10 per cent inspiration and 90 per cent subconscious plagiarism.)

Or consider Henri Poincaré, the brilliant French mathematician who in his essay “Mathematical Creation” describes boarding an omnibus in Coutances — already a sentence that feels like it should lead to a minor social comedy — and experiencing a mathematical illumination so sudden and entire that he felt “a perfect certainty” before verification, which is the mathematician’s equivalent of seeing the face of God and then, for conscience’s sake, checking the algebra at home.

Poincaré had been stuck. He had been grinding away at Fuchsian functions (I won’t even pretend to remember what those are) with all the conscious fervour of a man trying to open a jar whose lid is welded on by a vindictive deity.

Then he went on a geological excursion in his capacity as a mine inspector — because of course he did; polymaths in the nineteenth century had side gigs — and precisely when his mind was occupied with stepping onto public transportation, the solution vaulted the turnstile into awareness.

What are we to make of this? Poincaré himself spoke of a “delicate sieve” through which ideas must pass to enter consciousness. The phrase suggests something lacy and aristocratic, as though our best insights are powdered sugar shaken over the blunt pastry of awareness. But the lived experience is less pâtisserie and more plumbing.

We strain consciously at a problem — push, shove, apply every labelled cognitive wrench in the toolbox — and nothing budges. We keep getting the same message back from the universe despite all our efforts: We’re sorry, but all of our agents are busy serving other clients.

And then we stop. We go to the movies. We attempt to remember where we parked. We stand in line for coffee behind someone explaining and misinterpreting the complete works of Marshall McLuhan like that pretentious professor in Annie Hall. Turns out his whole fallacy is wrong.

But all the while, somewhere in the sub-basement of the mind below the level of consciousness, a committee quietly continues its work. Ghosts in the machine.

It is tempting to anthropomorphize this committee as a cadre of sleep-deprived, socially unconscious graduate students in cardigans, smoking metaphorical Gitanes and rearranging note cards pinned to corkboards. But they’re actually elfin cobblers.

“He’s finally shut up,” one of them says, gesturing upward toward the conscious self, who has wandered off to put the LP collection back into alphabetical order. “Now we can get something done.”

They shuffle memories you didn’t know were still in circulation: the offhand remark by a passerby, the diagram doodled on an envelope, the rhythm of a phrase half-heard on the radio in 1997. They test combinations without the ego’s constant editorializing. They are immune to the panic that says, “This must be solved now, or you are a bumbling idiot.” They are patient in a way the waking self is not.

And then — click. A configuration locks. A pattern aligns. The committee, apparently satisfied, slides the result upward through the sieve.

The conscious mind, which meanwhile has been busy composing a grocery list or worrying about whether it used “affect” correctly in an email, is suddenly handed a jewel. There is no sense of intermediate steps, no memory of the blind alleys explored below. Just the finished product, still warm.

And if this meandering, confused, contingent, unthinking route to a revelation doesn’t illustrate the  difference between human and artificial intelligence, I can’t think what does. That’s what all this flummery and persiflage have been leading to:

1. The Human Version: Slow Cooking in the Dark

In humans, creativity appears to involve several overlapping systems:

• Memory (messy, embodied, emotionally tagged)

• Association (loose, metaphor-prone, often irrational)

• Unconscious processing (the “committee in the basement”)

• Motivation and desire (which problems matter)

• Embodiment (fatigue, hunger, heartbreak, the sweet hormonal anticipation we have as winter gives way to rays from the sunrise lifting up sap in burbling streams, drawing forth new buds and opening petals. )
  

Human creativity is deeply tied to:

• Emotionally weighted memory

• Embodied states

• Long-term unresolved tension

• A sense of self across time
  

Crucially, humans care. A problem gnaws. An unsolved equation is humiliating. A melody feels urgent. That emotional charge reorganizes attention and memory. The unconscious keeps working partly because something matters.

“The role of this unconscious work in mathematical invention appears to me incontestable,” Poincaré wrote. “These sudden inspirations … never happen except after some days of voluntary effort which has appeared absolutely fruitless.”

Humans also forget in a particular way. Memories decay, distort, merge. This distortion is often fertile. It allows unexpected recombinations that feel original because they are partially misremembered.

2. The AI Version: Pattern Without Interior Weather

Artificial intelligence — the ability of computational systems to perform such seemingly human feats as learning, reasoning, problem-solving, perception and decision making — never rises to the level of consciousness ... but also has no unconscious processing per se. AI systems don’t go offline and incubate an idea. There is no basement committee of elves. There is no sleep. There is no delayed arrival of insight.

Instead:

• AI processes input.

• AI calculates probabilities over patterns learned during training.

• AI generates output step by step.

  
  

AI systems can analyze stylistic markers: recursive structure, qualifying clauses, tonal oscillation between high theory and mundane detail, self-aware humour, syntactic layering. They can produce text that statistically aligns with those features.

There is no eureka moment. Or even eurek-AI. There is no certainty. There is no feeling that something has clicked.

There is only next-token prediction guided by learned structure.

Even when a chatbot application produces something that resembles a revelation, it is the output of pattern recombination, not internal discovery. It does not solve a problem and then feel relief. It does not awaken with an answer. It does not care whether the answer is beautiful. (At least, not yet.)

3. Incubation vs. Instantaneity

One of the biggest differences is time.

Human creativity is temporally extended. It involves:

• Struggle

• Frustration

• Incubation

• Sudden integration
  

AI generation is temporally compressed. There is no background processing between sessions. If you close the window on whatever web interface is simulating conversation through text or speech, nothing continues brewing. There is no “two weeks later in a dream” effect unless you bring the problem back into the conversation.

Human insight often emerges because the brain continues reorganizing material during rest, distraction or sleep. The neural networks involved are biologically active systems constantly reshaping themselves.

Artificial neural networks, by contrast, do not self-modify during use (not in standard deployments, anyway). There is no spontaneous restructuring in response to unfinished tension. No midnight reconfiguration.

4. Constraint and Risk

Another major difference: risk.

Human creativity carries existential stakes. A failed novel can wound. A wrong proof can embarrass. A rejected symphony can devastate.

That risk alters cognition. It narrows attention, heightens emotion, intensifies memory consolidation.

Generative artificial intelligence systems face no humiliation. No longing. No dread of irrelevance.

To a tortured artist, that might not sound like an entirely bad thing. But it also means AI systems lack a key engine of originality: the pressure of identity.

Humans create partly to resolve inner conflict. AI generates because it is prompted.

5. But Here’s the Twist

Despite these differences, there is plainly some overlap at the structural level.

Both human brains and AI systems:

• Learn from exposure to patterns.

• Encode statistical regularities.

• Combine elements in novel configurations.

• Produce outputs not explicitly stored verbatim.

  
  

When a human has an insight, it is likely the result of unconscious recombination across networks shaped by experience. When AI generates a new metaphor, it is recombination across learned representations.

The difference is not that humans are magical and AI is mechanical, much as we might like that to be true. The difference is that humans are mechanical plus embodied, emotional, continuous, self-modelling organisms.

AI systems are mechanical without interiority.

6. The Most Important Difference

Humans experience creativity as meaning-making.

When you have a revelation, it reorganizes your sense of the world. It can alter who you think you are. It can change your trajectory.

When AI generates something creative, nothing about it changes.

No trajectory shifts. No identity evolves. No memory consolidates.

A great novel may move you. It will not move a software application or web interface.

If you think about it (no trajectory shift intended), this arrangement inverts our preferred mythology of agency. We like to believe that human thinking is a heroic, upright activity performed under bright lights: we grapple, we reason, we deduce. But that’s not us, mate. At least, not all of the time. That’s more the AI model.

We picture ourselves as muscular logicians, sleeves rolled, wrestling propositions to the mat. But the full-blown revelation suggests that for we the people, the real action occurs offstage, in the cognitive equivalent of a messy garage where no one is performing for applause. Consciousness, far from being the CEO, may be middle management — good at meetings, poor at innovation. The unvarnished truth is that when it comes to human thinking, we don’t know what to think. We really have no idea how three pounds of protoplasm in our skulls becomes conscious. Any theorizing about how thought arises should come with an inscription that also should be posted on the lintels of all churches, synagogues, temples and mosques: “Important if true.”

This would be less unsettling if the realm of the unconscious restricted itself to solving tasteful problems. Instead, it also chooses inopportune moments.

The way out of a maddening impasse in your stalled Great Canadian Novel arrives while you are brushing your teeth, forcing you to spit foam into the sink and lunge for a pen with minty hands.

The name of the actor you blanked on at dinner surfaces during a dental cleaning, when speech is impossible and your triumph must be expressed through muffled grunts. (In my most recent experience of this phenomenon, the actor was Stuart Margolin, that shifty friend “Angel” from The Rockford Files who used to live on Salt Spring Island.)

For students, that elusive exam answer blooms at 3:17 a.m. two weeks later, when there is no one to grade it and no partial credit for nocturnal epiphany. How many of us are still tortured by that common student dream in which we suddenly realize that the test worth 100 per cent of the mark is about to begin and that we somehow forgot to attend class all year?

And yet, for all that, there is still something consoling in this subterranean productivity. It implies that our failures of conscious manipulation — the stalled sentence, the unsolved equation, the blank stare at Question 4 — are not always terminal. They might be invitations to adjourn. To go board the omnibus. To let the mind’s quieter machinery continue without the klieg lights of willpower.

The revelation, when it comes, feels less like conquest and more like retrieval: as though the knowledge had been composting all along, generating heat in the dark.

How does an idea make it through the delicate sieve? Perhaps it is not brute force but simply a matter of trying on shoes to find a pair that fits. The unconscious tries on combinations the way one tries keys on a ring, and only when one turns smoothly — without scraping against too many contradictions or half-remembered objections — does it get promoted to awareness.

The “perfect certainty” Poincaré felt might be the phenomenological signature of internal consensus, the committee voting unanimously at last.

Of course, this romanticizes what is also a deeply ordinary process.

For every “Yesterday,” there are thousands of half-melodies that dissolve by breakfast. For every omnibus epiphany, innumerable bus rides during which nothing occurs beyond mild motion sickness. The sieve is delicate, yes, but also ruthless. It lets through only what coheres strongly enough to survive daylight.

Still, the next time you find yourself stuck — on a proof, a paragraph, a conversation you wish you had handled differently — it may be worth remembering that thinking is not the only mode of thought. You can, in a sense, fail productively. You can step away. You can go inspect a metaphorical mine. Take a deep breath and remember a handy little quote from the great filmmaker Alfred Hitchcock: Ideas come from everything.

Here’s an even better one from author and screenwriter Ray Bradbury: That’s the great secret of creativity. You treat ideas like cats: you make them follow you.

And somewhere beneath the chatter, in the humming dark, the committee will keep sorting, matching, discarding, until one day, while you are doing something gloriously irrelevant, it will hand you the answer as if to say: Here. You dropped this.

Maybe we’ll never fully understand how the brain gives rise to consciousness. Each one of us is a vast landscape of Rube Goldberg machines, with far too many balls in motion to catalogue or even count. Too many weights, coiled springs and cantilevers. Biological pulleys and levers, electrical currents, chemical energies. Our conscious selves are the captains of great ships, looking out to sea from high on the bridge. We can make inquiries and surmises about the cabins and the engine rooms down below, but are never able to see for ourselves.

But think of it this way.

Remember that old fairy tale collected by the Brothers Grimm about the exhausted shoemaker who left his work unfinished one night and woke to find that unobserved elves had toiled through the early hours to fashion a slab of leather into a beautiful pair of shoes? Computers have powerful algorithms on their side. They can throttle us at chess every time. But when it comes to creative soulfulness, my money’s on the unseen elves.
