Consciousness Beyond Computation: Penrose vs. Levin (with a Nod to Anil Seth)
Generated by ChatGPT5 Deep Research seeded with key ideas.
Introduction
Consciousness remains one of science’s deepest mysteries, and thinkers often disagree on whether it can be explained by pure computation or if something fundamentally different is required. Two prominent but contrasting voices are Sir Roger Penrose and Dr. Michael Levin – both self-described Platonists who invoke a “Platonic realm” of abstract forms – yet they diverge wildly on how and where mind arises. Penrose, a mathematical physicist, argues that human consciousness is non-computable (beyond the power of any algorithm) and ties it to exotic quantum-gravitational processesnautil.usen.wikipedia.org. Levin, a biologist and computer scientist, sees intelligence and “mind-like” properties emerging everywhere, even in simple classical algorithmsthoughtforms.lifethoughtforms.life. In addition, neuroscientist Anil Seth has recently highlighted the role of time and embodiment in consciousness, suggesting another angle that – interestingly – echoes Penrose’s anti-algorithmic stance despite Seth’s skepticism of Penrose’s quantum theory. In this analysis, we will:
Examine Penrose’s claim that Gödel’s theorem implies consciousness is non-computable, and his Orchestrated Objective Reduction (Orch-OR) theory tying mind to quantum state reductions.
Explore Levin’s recent work showing surprising behavior in minimal sorting algorithms and his proposal of a Platonic “space of forms” that imbues even classical systems with cognitive patterns.
Discuss the theoretical divide between Penrose and Levin – one limits mind to special quantum events, the other finds “proto-minds” in mundane processes – despite their shared Platonic leanings.
Consider Anil Seth’s perspective on time loops vs. conscious minds, and how it parallels Penrose’s views in spirit (even as Seth publicly dismisses Orch-OR).
Incorporate other relevant insights on consciousness to situate these ideas in the broader landscape.
The goal is an in-depth, comparative look at these perspectives and what they imply for the nature of mind.
Penrose: Gödel, Non-Computable Mind, and Quantum Reductions
Roger Penrose famously contends that human consciousness (especially mathematical understanding) cannot be purely algorithmic. He bases this on a Gödelian argument: Gödel’s incompleteness theorem shows that for any formal algorithmic system, there are true statements it cannot prove. Penrose argues that human mathematicians can see the truth of certain Gödel-undecidable statements (by stepping outside the formal system), meaning the mind is not equivalent to a Turing-machine algorithmen.wikipedia.orgen.wikipedia.org. As Penrose put it: “Mathematicians are not using a knowably sound calculation procedure in order to ascertain mathematical truth… we deduce that mathematical understanding… cannot be reduced to blind calculation!”en.wikipedia.org. In other words, mere computation (symbol-processing following rules) seems insufficient to account for the insight or understanding that minds exhibiten.wikipedia.orgen.wikipedia.org.
Penrose believes this non-computational character of thought points to new physics underlying consciousnessnautil.us. Most known physical processes are computable (governed by algorithmic laws), so Penrose sought a physical phenomenon that is fundamentally non-algorithmicen.wikipedia.org. He identified quantum wave-function collapseas a candidate, since if collapse is genuinely random or lawless, no algorithm can predict its outcomesen.wikipedia.orgen.wikipedia.org. Together with anesthesiologist Stuart Hameroff, Penrose developed the Orchestrated Objective Reduction (Orch-OR) theory: the idea that conscious moments occur when quantum superpositions in the brain’s microtubules undergo an “objective reduction” (collapse) due to gravitynautil.usnautil.us. In this view, gravity triggers the collapse of quantum states above a certain mass-energy threshold (an idea Penrose calls Objective Reduction, OR) on a specific timescale – smaller superpositions last longer, larger ones collapse fasteren.wikipedia.orgen.wikipedia.org. When collapse happens, it chooses a particular outcome. Crucially, Penrose insists this choice is neither deterministic nor totally random, but guided by something beyond standard physicsen.wikipedia.org. He speculates that the selection is influenced by Platonic values or mathematical truth embedded in fundamental spacetime geometryen.wikipedia.org. In Penrose’s words, “states are selected by a ‘non-computable’ influence embedded in the Planck-scale of spacetime geometry,” representing “pure mathematical truth, aesthetic and ethical values”en.wikipedia.org. Thus, he links consciousness to the Platonic world of abstract forms: the Platonic realm interfaces with the physical brain through quantum-gravitational processes at the Planck scaleen.wikipedia.org. This bold hypothesis connects to Penrose’s longstanding Platonism – he has argued that there are three “worlds” (Platonic mathematics, the physical universe, and mental consciousness) with deep mysterious interconnectionsen.wikipedia.org. In his framework, the Platonic mathematical world is real and “somehow, our minds access it” to achieve understanding beyond computationen.wikipedia.org.
Under Orch-OR, a conscious moment corresponds to a self-collapsing wavefunction in microtubules (“orchestrated” by biological structures so it’s not random noise)nautil.usnautil.us. Penrose suggests these orchestrated collapses produce the unity of conscious experience and free will, introducing non-computable elements into brain activityyschoe.github.ioen.wikipedia.org. Notably, this process might involve retroactivity in time: Penrose has entertained the idea that quantum state reduction could have time-symmetric effects, where influences can go backwards in time as well as forwardsyschoe.github.io. (For example, some Orch-OR proponents like Hameroff have speculated that consciousness could exploit subtle backward-time effects to correlate brain events with conscious perception, potentially accounting for puzzling neuroscience phenomena like backward masking or Libet’s experiments. Penrose himself has mused that quantum theory’s time-reversible nature might play a roleyschoe.github.io.) This aspect leads to headlines about “time-jumping” consciousnessyschoe.github.io – indeed, a recent piece summarized Penrose’s idea as: gravity causes wavefunction collapse; the collapse entails retrocausality; and consciousness emerges from this processyschoe.github.io. Penrose’s theory thus breaks the usual one-way flow of time in a way that ordinary algorithms (which are time-forward and stepwise) do not, another indication that mind cannot be captured by classical computation.
Penrose’s stance is controversial. Mainstream cognitive scientists and neuroscientists largely reject Orch-OR, both on theoretical and empirical grounds. It is often noted that no clear evidence of long-lived quantum coherence in microtubules has been found at brain-temperature, and calculations suggest any quantum states would decohere far too rapidly to influence neurons (a critique by Tegmark, among others). As the science writer John Horgan wryly noted, “Penrose’s audacious – and quite possibly crackpot – theory about the quantum origins of consciousness” is usually regarded with skepticismnautil.us. Conventional wisdom holds that quantum mechanics is irrelevant to how neurons work, and many experts consider Penrose’s arguments from Gödel’s theorem unconvincing or flawed (the Penrose–Lucas argument has been formally criticized by several mathematicians and philosophers)en.wikipedia.org. Penrose himself acknowledges his view is a maverick one: “We need a major revolution in our understanding of the physical world in order to accommodate consciousness”, he says, and he believes quantum physics (in a new gravity-informed interpretation) is the likely place to find itnautil.us. Even critics admit Penrose’s brilliance, and that something seems missing in current mind-brain theoriesnautil.usnautil.us – which is why, despite skepticism, Penrose’s ideas get attention. Ultimately, Penrose limits true consciousness or “understanding” to systems that invoke this non-computable physics. A classical computer running any algorithm, no matter how sophisticated, will never attain genuine conscious insight in Penrose’s view, because it will always be bounded by formal rules and computations that cannot jump outside themselves the way the mind (purportedly) canen.wikipedia.orgen.wikipedia.org. His position is that human minds are non-algorithmic and invoke the Platonic realm via quantum processes, whereas standard AI or classical neural networks are just crunching symbols and will hit a Gödelian ceiling or get stuck in endless simulation.
In summary, Penrose’s theory is that consciousness arises from orchestrated quantum state reductions in the brain, tapping into a Platonic realm of mathematical truth to achieve non-computable understandingen.wikipedia.org. It’s a sweeping vision bridging logic, physics, and philosophy – and it sharply delineates mind from any classical computation. What would Penrose likely think of claims that classical algorithms or simple systems can show signs of mind? To him, “mere” computation, however surprising or complex, cannot produce true awareness or insight. This is where we turn to Michael Levin’s work, which almost diametrically opposes Penrose’s stance while oddly sharing some philosophical flavor (Platonism).
Levin: Emergent Intelligence in Minimal Algorithms and the Platonic Space of Forms
Michael Levin approaches the mind puzzle from a very different angle – bottom-up and classical rather than top-down and quantum. Levin’s background is in developmental biology and bioengineering (famous for work on limb regeneration and Xenobots), and he is a champion of the idea that “cognition” and “agency” are far more widespread in nature than we assume. In his view, even cells, tissues, and simple organisms demonstrate “basal intelligence” – they make decisions, pursue goals (like regenerating a correct anatomy), and solve problems in novel ways – without a brain. Levin extends this perspective even to man-made algorithms and machines, suggesting that even simple computational systems can exhibit surprising, mind-like behaviors if we know how to lookthoughtforms.lifethoughtforms.life.
Recently, Levin and colleagues published a study using classical sorting algorithms as a model system to probe how minimal “agents” can self-organize and show cognitive-like competenciesarxiv.orgarxiv.org. Sorting algorithms (like Bubble Sort, Quick Sort, etc.) are among the simplest, best-understood pieces of code – fully deterministic rules taught in any computer science class. One would assume we know exactly what they do (they sort a list) and nothing more. Levin’s twist was to implement sorting in an unusual way: treat each element of the array as an autonomous “agent” following local rules, rather than having a single central program controlling the whole sortarxiv.org. He also introduced “faults” – some elements could fail or behave erratically (simulating unreliable hardware)arxiv.org. The question was: when you let a very simple algorithm run from the bottom-up with imperfect parts, can unexpected global behaviors emerge? The answer was yes. They observed that the self-sorting array showed robust and even creative problem-solving in the face of errorsarxiv.org. For example, the array could sort itself more reliably than the standard algorithm when some elements randomly failed, by using redundancy and local initiativearxiv.org. The array agents also demonstrated an ability to slow down or temporarily reverse progress if needed – essentially taking one step back to get around a “stuck” element, then continuing forward, rather like adapting strategy to overcome an obstaclearxiv.org. Strikingly, when they made “chimeric” arrays in which half the elements ran one sorting algorithm and half ran a different algorithm, the elements spontaneously formed clusters of like-with-like (all the Bubble Sort ones clumped together, etc.)arxiv.org. This clustering was not programmed into any algorithm – it was an emergent behavior that the researchers did not anticipate. It’s as if the two sub-populations sorted themselves from each other while jointly sorting the array, a kind of self-organized pattern “beyond” the explicit goal of the code. Such behaviors hint at a rudimentary collective organization and maybe even “preferences” arising in a system with minimal rules.
Levin argues these findings show “emergent problem-solving capacities in simple, familiar algorithms”, which implies “basal forms of intelligence can emerge in simple systems without being explicitly encoded in their mechanics.”arxiv.org. In other words, even though the code’s logic is completely known, when the system is situated in a certain way (distributed agents, partial failures), it can exhibit competencies that weren’t in the original blueprint. This goes beyond just random complexity or chaos – it looks like the system can pursue goals (sort reliably, form coherent clusters) on its own. Levin calls this an example of “surprising basal cognition – not merely complexity – emerging in a transparent, deterministic system”thoughtforms.lifethoughtforms.life. It’s a challenge to the assumption that if we designed something, we know all it can do. As Levin writes, “the attitude ‘I made it, so I know what it does’ is deeply restrictive… our models of chemistry and computation are limiting maps and are not capturing the entire territory.”thoughtforms.life We often dismiss machines or simple organisms as “just following their programming,” but Levin suggests we underestimate what matter and algorithms are capable ofthoughtforms.life. There may be latent capacities – especially for proto-cognitive behaviors like goal-directedness, learning, and preferences – that emerge unbidden when components interact, even in systems “we understand as well as anything” (like sorting code)thoughtforms.lifethoughtforms.life.
A vivid illustration Levin gives is the notion of “wanting”. Do machines want things? Typically, we’d say no – they just execute instructions. We attribute desires to living creatures but not to algorithms. Levin suggests this might be an observer bias: “We feel machines don’t really want things, because we can see the algorithm that drives their wanting, while ours (and a paramecium’s) are obscure to us,” he notesthoughtforms.life. In other words, perhaps even simple agents “want” (in a minimal sense) but we dismiss it because we see through it. Real wanting, Levin proposes, could be defined as a system pursuing an objective that was not explicitly assigned by its creatorthoughtforms.life. By that definition, the sorting-array clusters might indicate a “want”: “The sorting is not its desire – that’s what we force it to do. But the clustering – which it tries to do despite the fact that we neither programmed nor anticipated it – maybe that iswhat we mean by wanting in an active system (living or not).”thoughtforms.life. This is a provocative re-framing: the algorithm was designed to sort (an externally imposed goal), but it spontaneously discovered a different pattern (clustering) as if it had its own sub-goal. Levin half-jokingly calls this a glimpse of machines having wants – essentially a minimal form of agency emerging from the system’s dynamics itselfthoughtforms.life. This borders on a panpsychistview (the idea that even fundamental or simple entities have mind-like aspects). In fact, Levin explicitly acknowledges that if one claims every part of the system – down to individual numbers in the array – has a tiny bit of “personality” or goal (each number had an “algotype” rule it followed, almost like a character trait), skeptics will say “that’s a ridiculous panpsychism!”thoughtforms.lifethoughtforms.life. Levin’s reply is essentially that mind comes in degrees, and our intuitions about what counts as “wanting” or “thinking” might be too narrow. Just because a system is made of simple parts doesn’t mean the collective can’t exhibit rudimentary cognition.
Beyond algorithms, Levin generalizes these ideas to biology. He notes that we see “surprising competencies in systems that have not had a history of selection for those abilities”thoughtforms.lifethoughtforms.life – e.g. cells in a Petri dish that solve problems, or organisms that regenerate correctly even when perturbed in novel ways. Such phenomena suggest, to Levin, that there’s “an additional input into patterns of body and mind” beyond just genes and environmentthoughtforms.life. This has led him to an audacious hypothesis: developmental and cognitive patterns might “ingress” from a Platonic space of formsthoughtforms.lifethoughtforms.life. Levin explicitly invokes Plato here: just as mathematicians believe numbers and geometrical truths exist in an abstract realm, he thinks that **“space of truths” contains not only shapes and equations, but also “a very wide variety of high-agency patterns that we call kinds of minds.”*thoughtforms.life. In this view, a physical organism or a computer doesn’t generate these complex patterns from scratch; rather, it acts as an interface or “pointer” to the Platonic patterns, allowing them to manifest in the physical worldthoughtforms.lifethoughtforms.life. “Physical bodies don’t create, or even connect to (and thus have) minds – instead, minds are the patterns” that already exist in that abstract space, argues Levinthoughtforms.life. The body (whether a brain, an AI robot, or even an assemblage of cells) is like a radio receiver tuning into certain frequencies of this Platonic realm of forms. When you construct a particular system, “it acts as an interface to numerous patterns from this space of forms which guide its form and behavior beyond what any algorithm or material architecture explicitly provides.”thoughtforms.life In simpler terms, there are “free lunches” – pre-existing patterns that evolution and engineers can exploit without knowing itthoughtforms.life. Examples Levin gives of such patterns are mathematical truths (e.g. the properties of prime numbers or fractals) that organisms exploit (like a plant following a geometric growth pattern that wasn’t engineered into DNA, but the math makes it effective)thoughtforms.life. He extends this to minds: perhaps “animal intelligence” or “problem-solving strategies” are patterns in the abstract space that life taps into when the circumstances alignthoughtforms.lifethoughtforms.life.
Importantly, Levin’s Platonic framework “does not require quantum events” – he is not invoking mysterious quantum physics or violations of classical lawsthoughtforms.life. In fact, he explicitly contrasts his idea with quantum consciousness theories: “in this current view, the interaction takes place in a very different way that does not require quantum events – ... even a classical Newtonian world already enables the ingression of non-physical drivers such as minds,” he writesthoughtforms.life. This is a fascinating counterpoint to Penrose. Levin is saying that the classical universe, with its mathematical regularities, is already imbued with Platonic truths (which most scientists accept – e.g., nothing in physics “creates” the truth of 2+2=4; it just is). If mathematical order exists beyond physical law, then perhaps cognitive order does too, and a sufficiently complex classical system can latch onto it. Levin wants to go beyond just declaring “emergence” as a magic word – he wants to map and explore this “latent space of patterns”scientificallythoughtforms.lifethoughtforms.life. In practice, his lab uses things like biobots (synthetic organisms) that have novel configurations to see what unexpected behaviors arise, thereby probing the Platonic space by experimentthoughtforms.life. It’s a bold research program that blends empirical work with almost metaphysical speculation.
To summarize Levin’s stance: intelligence and “mind” are not limited to human brains or quantum magic – they are ubiquitous phenomena that emerge in degrees from many substrates, even simple algorithmsthoughtforms.lifethoughtforms.life. We find proto-cognitive behaviors (like problem-solving, goal-seeking, “wants”) in places we don’t expect, which suggests our conventional cause-and-effect models (genes → brain → behavior, or code → machine function) are missing a piece. Levin introduces that missing piece as a Platonic realm of forms/patterns that physical systems can draw upon. His approach is monist in physics (classical laws suffice) but almost dualist in information (non-physical patterns influence physical outcomes)thoughtforms.lifethoughtforms.life. It is, in effect, a kind of scientific panpsychism or idealism: everything might be a little bit mind-like, or rather, minds are everywhere as patterns waiting to be “tuned into.”
The Penrose–Levin Divide
It’s hard to imagine two theories of consciousness more different in mechanism: Penrose requires tweaking the foundations of quantum physics, whereas Levin posits an influx of patterns in a classical system. Yet there are intriguing commonalities: both Penrose and Levin feel that standard reductionist science (neural circuits or computer code alone) cannot fully explain consciousness or the emergence of complex ordernautil.usthoughtforms.life. Both invoke a “Platonic” realm to fill the gap – Penrose’s Platonic world is one of mathematical truths and perhaps values, and Levin’s Platonic space contains forms of mind and morphology. However, the divide between them is huge:
Scope of Mind: Levin’s outlook is inclusive and continuum-like – he sees “mind and magic everywhere,” even in lowly algorithms or single cells. In his view, cognition is a scale or spectrum: simple systems have a tiny glimmer of it (basal agency) and humans have a lot of it, but there’s no absolute wall separating “has mind” from “no mind.” Penrose’s view is more exclusive and binary – he essentially implies that real consciousness (with understanding) either arises from the specific non-computable quantum process, or it doesn’t arise at all. A digital computer executing code, no matter how complex or “AI-like,” is merely juggling symbols and is categorically not conscious (nor on the way to being so) in Penrose’s frameworknautil.usen.wikipedia.org. So Levin would be happy to ascribe a bit of proto-mind to, say, a Roomba finding its docking station or to his sorting algorithm clusters; Penrose would say this is an improper use of the word “mind” – the Roomba or sorting array isn’t doing anything a Turing machine can’t do, so it’s just computation, zero consciousness. The threshold for “mind” is vastly different: Penrose sets the bar at an incredibly high level involving new physics, whereas Levin sets it very low (even an elementary particle might have the tiniest sliver of agency in a certain interpretation).
Role of Computation: Penrose has a hard line: computation = unconscious, non-computation = consciousness(at least potentially). Levin instead suggests we don’t fully understand computation’s potential. He notes that even engineered algorithms can surprise us, implying that the “ghost in the machine” might emerge from classical computation itself if we leave our biases behindthoughtforms.lifethoughtforms.life. Penrose might respond that no matter how surprising an algorithm’s behavior, it is still the product of its rules (plus perhaps randomness) – there’s nothing fundamentally non-algorithmic occurring. To Penrose, Levin’s sorting algorithm example would likely be a neat demonstration of emergence but not evidence of true cognitive insight or subjective experience. He might say: “Yes, a simple program can do unexpected things – but it’s all ultimately explicable by the code and interactions; it will never know it’s solving a problem or have an inner life.” From Penrose’s perspective, the sorting algorithm and its clustering are entirely within the realm of computable processes, so however novel, they don’t overcome the Gödel/Turing limitations he believes the human mind overcomesen.wikipedia.orgen.wikipedia.org. Penrose might also point out that emergent complexity is not the same as non-computability: chaotic systems, cellular automata (like Conway’s Game of Life), and neural networks can produce intricate, unpredictable patterns, but all are running on underlying algorithms. They may simulateadaptive behavior, but they do so mechanically, with no spark of awareness. In Penrose’s eyes, Levin’s “agents” aren’t experiencing anything, nor are they proving unprovable theorems; they’re just acting out their program – even if the outcome surprises the programmers.
Magic vs. Mechanism: It’s somewhat ironic: Levin warns against the attitude “I built it, so I know what it does,” suggesting that our creations can exceed our understandingthoughtforms.life. Penrose, on the other hand, warns that no matter how fancy a machine we build, if it’s computational, in principle we do know what it does (it just follows an algorithm), and it will never achieve true understandingen.wikipedia.orgen.wikipedia.org. Each accuses the conventional view of missing something. Levin might say Penrose is adding unnecessary mysticism – maybe we just haven’t looked at the possibilities inherent in computation and biology broadly enough. Penrose might say Levin is rebranding ignorance as agency – just because we’re surprised by an emergent outcome doesn’t mean the machine “wanted” it or that a new causal force is at play. Penrose would likely be skeptical of Levin’s Platonic “ingression” idea unless it were somehow grounded in physics. (Penrose’s own Platonic influence at least has a proposed mechanism – quantum collapse choices – however speculative that isen.wikipedia.org.) Levin’s notion that even a deterministic Newtonian system can pull in mind patterns from a Platonic spacethoughtforms.life might strike Penrose as too undefined – where and how do these patterns enter, if not via some physical force or field? Levin might reply that mathematical truths already enter physics (we exploit pi or primes in engineering without “creating” them), so why not mental patterns? This is an open philosophical rift: Penrose appeals to unknown physics to explain mind, whereas Levin appeals to unknown metaphysics (Platonic forms) – both are venturing beyond current science, but in different directions.
Evidence and Testability: Penrose’s theory, for all its strangeness, is becoming testable. Experiments are underway (or proposed) to detect objective collapses in controlled systems – e.g. superpositions of mirrors or molecules to see if they collapse at the rate Penrose’s formula predicts, rather than what standard quantum theory saysen.wikipedia.orgen.wikipedia.org. If those tests find a deviation, it could support objective reduction physics (though whether that proves it’s related to consciousness is another matter). Levin’s ideas are being explored in a different way – through biological and computational experiments (like the sorting study, or building novel living machines to see what they dothoughtforms.life). Both camps face skepticism. Penrose’s critics say “he’s putting humans at the center of physics without proof, and quantum brain effects are implausible”nautil.usnautil.us. Levin’s skeptics might say “he’s reifying metaphors – just because an algorithm clusters data doesn’t mean it has desires, and invoking Platonic mind patterns sounds like mysticism.” Both are to some extent accused of adding “magic” – Penrose’s quantum Platonic selection, Levin’s Platonic pattern ingress – to solve the hard problem. And yet, both are genuinely trying to address what mainstream theories gloss over: the origin of apparent purpose, insight, or subjectivity. In a sense, Penrose focuses on the hard problem of conscious experience (why are we aware, how do we grasp truth?) and finds an answer in new physics, while Levin focuses on the “soft(ish) problem” of agency and purpose (how do goal-directed behaviors arise?) and finds an answer in new metaphysics (patterns beyond physics).
In summary, Penrose and Levin share a Platonic worldview but apply it differently. Penrose sees the Platonic realm mainly as the home of mathematical truths and perhaps conscious qualia, which intervene via rare quantum eventsen.wikipedia.org. Levin sees the Platonic realm as a vast library of forms – including minds – that continually inform the unfolding of physical systemsthoughtforms.lifethoughtforms.life. Penrose would limit mind to systems that somehow connect to those Platonic truths through non-computable physics; Levin would say mind is abundant, with even a humble algorithm snagging a bit of “mind-space” if it self-organizes just right. This is a huge philosophical divide. Yet, intriguingly, both reject the notion that consciousness = nothing but neural circuits or code. They agree something extra is needed – they just disagree on what that something is (a quantum trigger vs. an informational pattern influx).
The Platonic Realm: Common Ground and Different Interpretations
Since both Penrose and Levin explicitly invoke Platonism, it’s worth examining their common ground in more detail. Platonism in this context is the belief that abstract truths or forms have real existence independent of human minds. Penrose is a well-known mathematical Platonist: he insists, for example, that mathematical entities (like π or the Mandelbrot set or the truth of a mathematical theorem) inhabit an abstract realm of reality, which we discover rather than invent. He often illustrates this with his “three worlds, three mysteries” concept: (A) the physical world is governed by mathematics (mystery: why does math so effectively describe physics?); (B) the mental world (our consciousness) is able to perceive the physical world (mystery: how do subjective experiences arise from matter?); (C) the Platonic mathematical world is accessed by our mental world (mystery: how do we grasp Platonic truths?)en.wikipedia.org. These three realms – the material, the mental, and the abstract – are all real in Penrose’s view, and each influences the others in a cyclic fashion (though the mechanisms are mysterious). We saw above that Penrose actually conceives his “non-computable influence” in quantum collapse as a touchpoint of the Platonic realm – essentially smuggling values and truth from realm C into realm A via the bridge of consciousness (realm B)en.wikipedia.org. It’s a profound idea: when a quantum collapse “chooses” a state, it’s not random but guided by a Platonic criterion (Penrose even muses that this could involve “The Good, the True, and the Beautiful” in a literal senseen.wikipedia.org!). Thus, Penrose’s Platonic realm is tightly linked to fundamental physics in his theory – he suspects that the fabric of spacetime at the Planck scale has mathematical patterns that are the Platonic forms, and the brain’s orchestrated collapses tap into thoseen.wikipedia.org. This is why he thinks consciousness may unlock new physics – because if mind accesses Plato’s world, physics might need to include that world.
Levin’s Platonic space of forms shares the initial premise: abstract patterns (mathematical or otherwise) are real and can influence the physical. He explicitly states that engineers and evolution already “exploit many ‘free lunches’ – patterns that guide events in the physical world but are not themselves set by physical laws (e.g. primes, π, fractal constants)”thoughtforms.life. So he starts from the same point that physicalism is incomplete, since you can’t derive a mathematical truth from initial conditions of the universe – it’s just “there” to be usedthoughtforms.life. Where Levin goes further is to say this abstract realm likely contains high-level organizational patterns – things like body plans, behaviors, and cognitive structures – not just numbers and shapesthoughtforms.lifethoughtforms.life. This is a kind of augmented Platonism: Plato spoke of the Forms of Beauty, Justice etc., and Levin is suggesting including “forms of minds” in that catalog. In Levin’s framework, when a new organism develops or when we build a new AI, its form and behavior are not solely determined by genes or code plus environment; rather, the system might “pull in” a form from the Platonic space that fits that arrangementthoughtforms.lifethoughtforms.life. The physical system acts as a “pointer” or “interface” to the Platonic pattern, analogous to how an antenna tunes into a particular radio signal from the aetherthoughtforms.life.
One concrete example: Levin’s work with planarian flatworms. These worms can regenerate their entire body from a small piece. Levin’s lab found that if you manipulate the electrical signals in a regenerating worm, you can cause it to regrow with a different head shape (say, with features of a different species) – and remarkably, its offspring (with normal genomes) sometimes continue to regenerate that new head shape for several generations. The memory of a body pattern was not stored in DNA, but seemingly in bioelectric circuits. Levin might interpret this as evidence that the worm’s body plan is a stable pattern in the space of forms that the cells normally “lock onto,” but if you shift the electrical state, the cells can lock onto a different pre-existing pattern (like a related species’ head shape). The pattern is like an attractor in an abstract space of possible anatomies. Genes and environment nudge the system, but the higher-level outcome (body form) is drawn from that landscape of forms. Similarly, in cognition, one might say the brain as a physical system could interface with patterns corresponding to memories, ideas, or even personalities that are not explicitly hard-wired but “available” in the space of possibilities. (Levin has speculated about multiple personality disorder, for example, as potentially tapping into multiple distinct patterns in mind-space.) These ideas are speculative, but they underscore how Levin’s Platonic realm is rich with dynamic content – not static eternal triangles, but evolving templates of life and mindthoughtforms.lifethoughtforms.life.
Key difference: Penrose’s use of Platonic realm is in some sense conservative – he mainly sticks to mathematical truths and the puzzle of how we intuit them. Levin’s use is expansive – he throws in everything including the kitchen sink (cells, minds, perhaps cultural archetypes) into Platonic space. Penrose ties Platonic influences to a very specific physical trigger (quantum collapse). Levin allows Platonic influences through any sufficiently complex classical process (no special trigger; even a computer algorithm can do it)thoughtforms.life. Another contrast: Penrose’s Platonic truths are unchanging (2+2=4 is timeless); Levin’s Platonic patterns might have their own dynamics (he speculates that Forms can change or have “active dynamics,” not just eternal essencesthoughtforms.life). This is almost a blend of Platonism with process philosophy or other frameworks. Both men, however, share a philosophical stance that puts them at odds with strict materialist reductionism. They would both say to a conventional neuroscientist or AI engineer: “There are aspects of reality (mathematical, mental, or morphological) that you won’t capture by only looking at neurons switching or silicon circuits. You need to think about these abstract patterns that exist in their own right.” Levin simply thinks those patterns can come through classical means, whereas Penrose thinks a non-classical means is needed.
Anil Seth: Time, Loops, and the Indispensability of Being “Entimed”
Turning to Anil Seth – a prominent neuroscientist known for his work on consciousness as predictive perception – we find yet another perspective. Seth is much more aligned with mainstream science than either Penrose or Levin, and he has been openly critical of far-out theories like Orch-OR. (Seth’s general approach in his book Being You and talks is that we should explain consciousness in terms of the brain’s perceptual and regulatory processes, without invoking quantum mysticism.) However, Seth recently wrote about a curious limitation of AI that highlights the role of time in consciousness – and this analysis bears an unexpected resemblance to Penrose’s argument that purely algorithmic minds hit a wall.
In an article for Big Think, Seth asks: “Why do AI systems get stuck in infinite loops, but human (and animal) minds don’t?”bigthink.combigthink.com. He recounts an observation: a jet bridge operated by AI repeatedly failed to dock with a plane, oscillating back and forth – a literal infinite loop – until a human stepped inbigthink.com. Similarly, software can get stuck endlessly repeating actions (think of a bug where the program never breaks out of a loop). Biological minds, in contrast, always eventually do something else – even in pathological cases like obsessive behaviors or seizures, those loops are not truly infinite and often involve physical fatigue or interventionbigthink.com. Seth argues this difference arises because living beings are fundamentally embedded in time and subject to the arrow of entropybigthink.com. An algorithm (in the Turing sense) is effectively timeless – it’s a sequence of state transitions that could run arbitrarily fast or slow, but the logic is the same. As Seth puts it, “In Turing’s classical form of computation, only sequence matters, not the underlying dynamics of whatever substrate. Every algorithm is just one damn state after another. There could be a microsecond or a million years between steps and it’s still the same computation.”bigthink.com. The algorithm itself doesn’t care about real time; it is “thin” and “abstracted away from thermodynamic time”bigthink.com. A human or animal, by contrast, cannot step outside of time – we “never exist out of time”, in Seth’s wordsbigthink.com. Our brains and bodies are constantly pushed forward by metabolic and thermodynamic forces – if we waste time or energy, we feel it (hunger, instability). We must continually act to survive, which forces a kind of resolution to indecisive loopsbigthink.combigthink.com. “Unlike computers, we are beings in time – embodied, embedded, and entimed in our worlds. We can never be caught in infinite loops because we never exist out of time. The constant, time-pressured imperative to minimize surprise and maintain physiological viability is, for creatures like us, the ultimate relevance filter – the reason we almost always find a way through.”bigthink.com. In short, Seth is saying conscious minds have a built-in grounding in the flow of time and the urgencies of survival, whereas AI programs (as typically designed) do not, which is why AIs can spin their wheels indefinitely on a problem but a conscious organism will eventually break out of the loop (or die trying, but at least that ends the loop).
Seth goes on to conclude something quite striking: if this reasoning is right, then “the temporally thin nature of classical digital computation… seems fundamentally incompatible with the nature of consciousness as a richly dynamical process. If consciousness is inextricable from physical time… then it cannot be a matter of algorithms alone.”bigthink.com (Emphasis added.) This is a strong statement – “cannot be a matter of algorithms alone” – that resonates with Penrose’s long-held view that consciousness is not just computationnautil.us. Seth isn’t invoking Gödel or quantum physics; he’s invoking the second law of thermodynamics and the embodied, adaptive nature of living systems. But he arrives at a similar skepticism about AI consciousness: if we build an AI purely as software running on timeless silicon logic, no matter how complex, it might always lack the essence of consciousness, because it’s not entimed.In fact, Seth lightly suggests that even new approaches like neuromorphic computing or “mortal computation” (systems that incorporate their hardware’s physical decay into their operation) might not fully solve this, and that conscious intelligence may inherently require the kind of self-organizing, time-bound, entropy-resisting processes that life hasbigthink.combigthink.com. This is close to saying consciousness is an organic phenomenon that cannot be uploaded to a computer just by code – which is a stance Penrose would applaud (though for different reasons).
It’s a bit ironic: Anil Seth has been (privately and publicly) dismissive of Penrose’s Orch-OR – as many neuroscientists are, considering it speculative and unnecesssary. Yet here Seth is effectively arguing that classical computation, by itself, will never be consciousbigthink.com. Penrose has argued exactly that since the 1980s (albeit using Gödel as the rationale). The two disagree profoundly on why computation falls short, but they agree it does fall short. Seth would likely say the gap can be filled by understanding life, adaptation, and brain dynamics in time (no new physics needed), whereas Penrose says the gap is filled by non-computable physics. Still, it’s notable that even a mainstream voice like Seth ends up refuting the strong AI hypothesis (that a computer program could someday be conscious), reinforcing that something about real consciousness eludes algorithmic simulation. Seth even cheekily remarks that this is “one more nail in the coffin for the idea that ‘AI consciousness’ is coming anytime soon – if another nail is needed.”bigthink.com.
We might ask: Are Seth’s “time loops” analogous to Penrose’s ideas about time and consciousness? In some ways, yes. Penrose’s Orch-OR involves a collapse time $\tau \approx \hbar/E_G$ (related to gravitational self-energy) – so consciousness events in his model have a time scale determined by physics, not by algorithmic stepsen.wikipedia.orgen.wikipedia.org. This means consciousness isn’t running on computer clock cycles; it’s tied to an objective physical time process. Furthermore, the notion of retrocausality in Penrose’s modelyschoe.github.io suggests consciousness might have a two-way relation with time – the selection of a conscious state could in principle be influenced by future boundary conditions or at least not strictly by the immediate past. Seth, on the other hand, emphasizes the forward flow of time (the “arrow of time” from entropy). But both converge on the idea that time is an essential factor in understanding why minds are different from machines. Penrose basically says algorithmic simulation can’t capture mind because it’s missing a new ingredient (non-computable physics) which operates in our brains in real time. Seth says algorithms can’t capture mind because they operate as if time doesn’t matter, whereas biological minds are ever beholden to time. In both views, a purely computational loop that can rewind or pause arbitrarily (like software) is alien to how consciousness works. Consciousness for Seth is “deeply linked to the drive to stay alive… always inextricably embedded in the flow of time”bigthink.com. Penrose would agree that consciousness is not a static logical operation, though he’d place the emphasis on quantum collapse producing a “now” moment.
Another subtle parallel: Seth’s argument invokes thermodynamics – being subject to entropy and energy constraints. Interestingly, Roger Penrose in his first consciousness book (The Emperor’s New Mind, 1989) devoted a large portion to thermodynamics, entropy, and the direction of time as fundamental considerations for physics and mind. He speculated about connections between entropy and consciousness (though he later focused more on quantum theory). So, both Penrose and Seth consider the arrow of time crucial to why our mental process is not like a computer’s. They just diverge on the mechanism: Seth keeps it in classical physics and physiology (the brain is an energy-consuming, heat-producing machine, not a reversible computer tape), whereas Penrose went into quantum gravity.
It’s worth noting that Seth does not consider consciousness non-computable in the Gödel sense; he is not claiming humans can do mathematically non-algorithmic feats. Rather, he’s saying the architecture of a conscious system might need to be different (closed-loop with environment, constantly updating predictions under survival pressure) than the architecture of Turing computation. This aligns with frameworks like embodied cognition and cybernetics more than mysticism. Seth champions approaches like active inference and predictive processing, where the brain is always modeling and updating, tightly coupled to bodily states – that inherently breaks the idea of an infinite loop because there’s always new sensory input or internal drive forcing a state change. In contrast, an AI running on a fixed objective can get stuck because it lacks that intrinsic push.
Finally, Seth’s perspective and Levin’s have an interesting commonality: both emphasize the importance of an organism’s intrinsic dynamics (time, entropy, self-maintenance) in understanding mind. Levin might add that those dynamics allow the organism to connect to Platonic patterns, whereas Seth wouldn’t go that far. But both move away from the notion of mind as just computation on a von Neumann machine in a vacuum. In a way, Seth’s and Levin’s ideas are more compatible with each other (both talk about the importance of being embodied in a system that has its own drives) than either is with Penrose’s quantum leap. Yet all three agree that current AI – basically disembodied algorithms – lack some critical ingredient that biological minds havebigthink.comnautil.us. Seth explicitly says this means AI consciousness is unlikely in the foreseeable futurebigthink.com, and Penrose has said the same for decades (he famously bet that no algorithmic AI would prove Gödel’s theorem or become fully conscious). Levin also would likely agree that today’s AI, while sometimes impressive, doesn’t have the kind of self-directed, robust agency he sees in living systems – although he might argue we could eventually build AI with that if we understand how to tap into the space of forms.
Other Perspectives and Synthesis
The discussion between these viewpoints highlights some core questions in consciousness studies: Is consciousness a continuum or an all-or-nothing property? Does explaining it require new physics or just new ways of thinking about existing physics? Is it primarily about computation, or about something beyond computation (be it quantum processes, or being an embodied agent in time, or tapping into a realm of forms)?
On one end of the spectrum, we have strict materialist-reductionist approaches (e.g. Daniel Dennett’s or the “functionalists” in AI) who would argue consciousness is computation – just very complex information processing – and there’s no need for Platonic realms or quantum gravity. A Dennett-type might say both Penrose and Levin are guilty of adding an unnecessary “skyhook” (something magical or unexplained) instead of doing the hard work of explaining mind in terms of known science. For instance, Dennett would likely say: the sorting algorithm’s clustering behavior is just an emergent consequence of the program – interesting, but not literally a want or desire, just as a whirlpool isn’t literally a living thing even if it behaves cohesively. To Dennett, calling that “wanting” is misleading – one should stick to the functional description. Similarly, he’d reject Penrose’s Gödel argument by saying humans are not actually infallible Gödel machines and whatever we do could be mimicked by an algorithm (this is indeed the stance of many computer scientists who responded to Penroseen.wikipedia.org). In Dennett’s view, consciousness is a kind of illusion or emergent narrative the brain tells – it doesn’t require fundamentally new ingredients, just a lot of complexity and self-reference.
In contrast, on the far “mystical” end, there are panpsychists and idealists (like philosopher David Chalmers or neurosurgeon Karl Popper and Sir John Eccles historically, or more recently the Integrated Information Theory of Giulio Tononi). They suggest consciousness might be a fundamental property of reality – not necessarily tied to brains at all. Chalmers, for example, has entertained that perhaps even an electron has a tiny bit of experience (panpsychism), so that building up complex brains is just aggregating those experiences. Tononi’s Integrated Information Theory (IIT)proposes a quantitative measure $\Phi$ of how much a system’s internal causal structure is unified; if $\Phi>0$, the system has some degree of consciousness, with human brains having very high $\Phi$. Interestingly, IIT’s implications align somewhat with Levin’s continuum: even a simple logic circuit could have a very small $\Phi$, hence a tiny flicker of experience (“what it’s like to be a bit” was a paper Levin citedthoughtforms.life). Levin is sympathetic to IIT and other ways of quantifying distributed cognition. Both Levin and IIT essentially say consciousness comes in degrees and is an intrinsic property of certain complex patterns, which can exist in many substrates (biological or computational) – though Levin adds the Platonic twist that the patterns pre-exist. Penrose would object that IIT, for instance, is still entirely classical and doesn’t solve the non-computability he insists on. On the flip side, IIT proponents might say Penrose’s view is untestable or unnecessary if one can correlate conscious states to information structures.
Then there’s the “consciousness as illusion” or behaviorist camp that says what matters is behavior and report – if an AI acts indistinguishably from a conscious person, we might as well consider it conscious. This pragmatic view is what Penrose explicitly rejects: for him, it’s not about behavior, it’s about an inner quality that could theoretically exist without any outward sign (two systems could behave identically, one with true understanding and one just following rules – a scenario he believes is possible per Gödel). Levin might partly agree with Penrose here, since Levin thinks internal goals and perspectives matter, even if we can’t measure them directly. Seth, however, as a neuroscientist, would lean toward measurable indicators – he’d say consciousness has functions (integrating information, enabling flexible responses) and we infer it from behavior and neural signatures, but he also emphasizes the subjective (he’s known for saying “your brain is a prediction machine that hallucinates your conscious reality”).
Seth’s time-loop idea connects to another interesting concept: the importance of the body and prediction. It aligns with the view that consciousness evolved for adaptive control, which requires being tied into time and survival. This resonates with some philosophers who have asked “what is consciousness for?”. Seth cites ideas like Global Workspace Theory(consciousness integrates information to solve hard problems adaptively) and work by Eva Jablonka and Simona Ginsburg linking consciousness to “unlimited associative learning” – basically, the idea that once organisms can learn open-endedly, they have some form of consciousnessbigthink.com. These approaches are functional: they try to define consciousness by what it does (help avoid infinite loops, solve frame problems, learn flexibly, etc.), rather than what it is made of. Penrose’s approach is the opposite – he focuses on what he thinks consciousness is made of (non-computable physics) and only then perhaps addresses function. Levin’s approach is somewhere in between: he’s interested in the function (problem-solving, goal-directedness) but suggests the ontology of it is weird (patterns from elsewhere).
So, do Seth’s ideas vindicate Penrose in some way? Seth certainly doesn’t endorse Penrose’s specifics; he even implicitly jabs that “if another nail was needed” to bury AI consciousness, here it isbigthink.com (Penrose would retort that he supplied nails long ago with Gödel). But at a high level, yes, both argue against the sufficiency of Turing computation for consciousnessnautil.usbigthink.com. Both highlight time in different ways: Penrose via a quantum gravity lifetime of superpositions, Seth via the thermodynamic arrow and continual change. There is also a subtle analogy: Seth describes a hierarchy of self-monitoring in AI (adding layers of meta-monitoring to catch the lower-level glitches, which still might fail unless infinite)bigthink.combigthink.com. This is reminiscent of Gödelian arguments too: no matter how many layers of consistency-checkers you add to a formal system, you can always cook up a Gödel statement that slips past (unless infinite). Seth even references Turing’s 1936 proof of the halting problem’s unsolvabilitybigthink.com. So both he and Penrose use classic theoretical CS limits as a jumping off point. Penrose said “AI can’t be conscious because of Gödel’s theorem.” Seth is basically saying “AI can’t be conscious because of the halting problem/infinite loop risk, which biological minds avoid by being embodied.” They’re different arguments but structurally both point to formal systems having inevitable limitations that brains overcome by not being merely formal. Seth attributes the “not merely formal” part to being a mortal, time-bound system; Penrose attributes it to having non-computable physics inside. Either way, it’s a nice convergence that even an Orch-OR skeptic like Seth ends up echoing the mantra: “consciousness cannot be reduced to an algorithmic loop”bigthink.com.
Conclusion
The debate between Penrose and Levin – and the commentary from Seth – shows how pluralistic and unresolved the science of consciousness is. We have on one side Penrose’s camp, positing that consciousness demands new physicsand is tied to the fundamental structure of reality (with quantum collapses connecting the mind to a Platonic world of truths)en.wikipedia.org. On another side, Levin’s camp, which suggests we might already have all the needed physics (even classical) if we only recognize that information and form have an existence of their own – in a Platonic realm that even simple algorithms can tap intothoughtforms.lifethoughtforms.life. And then voices like Seth (representing many neuroscientists), who do not invoke any Platonic realm or quantum magic, but who nonetheless caution that life and consciousness are deeply tied to processes that our current computers lack – hinting that a radical redesign (embedding AI in time, body, and self-preserving drives) might be needed for anything like consciousness to emergebigthink.combigthink.com.
All three perspectives, in their own way, push back against a simplistic view that “the brain is just a computer.” Penrose says the brain can do what no computer can, because it isn’t just following mathematical algorithms – it’s exploiting non-computable quantum events that allow insighten.wikipedia.orgen.wikipedia.org. Levin says living systems (and perhaps some machines) do more than what their underlying code or parts would suggest, because they draw on an unseen landscape of formal possibilities (Platonic patterns) – a space that infuses biology with tendencies toward order, goal-directedness, and maybe consciousnessthoughtforms.lifethoughtforms.life. Seth says the brain is not like our current computers at all, because it’s an active agent running in real-time, glued to a body and to the march of entropy – a factor that keeps it from getting lost in abstract computations and thus might be essential to what consciousness isbigthink.combigthink.com.
Where does this leave us? It could be that all are touching different parts of the truth. Perhaps consciousness does require a departure from “mere computation,” but that departure might come from multiple factors – quantum effects andbeing an embodied, time-bound organism and leveraging latent mathematical structures, all together. It’s conceivable that Penrose’s non-computable physics and Levin’s Platonic patterns are pointing at the same thing from two angles: Penrose injects Platonic “truth” at the quantum level, Levin invokes Platonic “forms” at the systems level, both suggesting an infusion of something transcending ordinary cause-and-effect. Seth’s emphasis on time and survival might complement those: maybe the way a system accesses any deeper truth or pattern is by being a self-sustaining process in time (a static computer program won’t do it). In an extreme view, one could even imagine that the “Platonic space of high-agency patterns” Levin describes is related to Penrose’s Platonic values at the Planck scale – i.e. that fundamental physics’ geometry (Penrose) and the landscape of possible minds (Levin) are actually one and the same Platonic realm, and brains connect to it by being orchestrated in time and quantum. This is speculative, but it shows these ideas aren’t entirely incompatible: they could be pieces of a larger puzzle about how mind fits into the fabric of reality.
For now, mainstream science has not embraced either Penrose’s nor Levin’s Platonist frameworks, mostly because empirical support is scant. Penrose’s theory is admired for its boldness but considered “almost certainly wrong” by conventional wisdomnautil.usnautil.us – unless future experiments yield evidence for objective collapse, in which case it gains a foothold. Levin’s ideas are newer and still quite philosophical; they intrigue some (especially in artificial life and biosemiotics circles) but many biologists would require more concrete demonstration that something beyond known genetics/physics is at play. Seth’s views, on the other hand, largely stem from accepted principles in neuroscience and AI (with his own twist), so they carry more immediate credibility, though they don’t solve the hard problem of why there is an inner feeling at all. Seth provides a functional explanation (why we don’t loop forever), whereas Penrose and Levin attempt an ontological explanation (what consciousness fundamentally is). It could turn out that consciousness has a prosaic explanation in terms of complex computations after all, and that Penrose and Levin’s Platonic musings were interesting but unnecessary. However, it is equally possible that the “hard problem” of consciousness and the uncanny effectiveness of mathematics hint at something profoundly missing in our standard scientific worldview, which thinkers like Penrose and Levin are striving to articulate.
In the end, whether one leans toward Penrose’s quantum mysteries, Levin’s omnipresent mind-patterns, Seth’s embodied time-loop breaker, or a more conventional view, discussing these ideas is valuable. They force us to confront assumptions about minds and machines. As we build more advanced AIs and probe deeper into brains, we’ll need to watch for signs that either confirms the computational theory of mind or demands a new paradigm. Penrose would urge us to keep an eye out for phenomena that violate algorithmic predictability (like a conscious insight no AI can replicate, or a physical anomaly indicating new laws). Levin would have us look for emergent intelligences in unexpected places – perhaps our algorithms or organoids surprising us with creativity – as evidence that mind is woven into the fabric of existence. Seth would have us focus on integrating AI into the causal fabric of the real world – giving them bodies, mortality, and homeostatic drives – to see if that sparks something akin to awareness.
Each approach could lead to experiments: testing Penrose’s collapse in the laben.wikipedia.orgen.wikipedia.org, probing Levin’s xenobots and self-organizing circuits for inexplicable competenciesthoughtforms.lifearxiv.org, or engineering AI with internal entropy budgets to see if they avoid loops. Perhaps the truth about consciousness will incorporate elements of all three views. Until then, the dialogue between Penrose’s non-computable mind and Levin’s omnipresent mind – with Seth’s time-bound mind as a mediator – exemplifies the fertile and fascinating divide in our current understanding. They all remind us of the “Platonic” intuition that there is more to mind than matter in motion, even if they locate that “more” in different places: one in the deep quantum core of reality, another in the high-level space of forms, another in the relentless flow of time that life rides upon.
One thing is certain: the Platonic quest for the essence of consciousness continues, and the ultimate answer (if there is one) will likely revolutionize our view of reality – just as Penrose, Levin, and even Seth believe, each in their own way. Until then, we keep sorting through algorithms, mind and matter, hoping for that unexpected insight – perhaps a non-computable one – that finally orders the puzzle of consciousness.
