FWIW, I have experienced (in retrospect) qualia without consciousness. When I wake in the morning, usually it is either from dreams or from dreamless sleep, but a few times, when I have awakened, I have realised that for the last few minutes I had been lying there idly ruminating about random stuff, as I might do while awake, but without being aware of myself. Experience was there, but no awareness of experience. Then consciousness turned on and I was able to observe what had just been happening.
I do not think it is a useful state of mind.
When I publish something on my blog, I generally also post about it on Twitter. In this case, David Sartor prompted me through dialogue to state my claim more clearly, and I'd like to include that here:
i guess what i'm saying is that when you dissolve the higher level self-reflective cognition, the low level self-reflective qualia does not go away.
I'd like to thank Guy for the conversation we had on 26 November 2025.
Late last year, the rationalist community leader and artificial intelligence researcher Eliezer Yudkowsky claimed that chickens do not have qualia:
This caused something of a stir – for what seem to me like obvious reasons. Apparently Eliezer has said similar things before, in a 2014 Facebook post – the pig post, as an animal welfare researcher friend referred to it:
When Eliezer's tweet went viral, Portuguese writer and Twitter personality Guy – also known as Rival Voices – was attending the rationalist campus and convention center Lighthaven in Berkeley for their yearly writing residency Inkhaven. He saw an opportunity for a blog post trying to unpack why Eliezer might believe what he does. Guy works with the philosopher Ned Block's framework, which distinguishes between phenomenal consciousness and access consciousness. From Wikipedia:
Guy thinks this framework should be helpful for understanding Eliezer's stance. As he speculates in his post, Eliezer Yudkowsky Thinks Chickens (and Babies) Aren't Conscious and I Know Why:
Personally, I'm not so sure the distinction between phenomenal and access consciousness is so clear cut, but that's another story. My own take is that I think that Eliezer simply misidentifies a certain type of self-reflective cognition with consciousness itself, or perhaps what matters is this is what he chooses to value. Maybe this is to be expected for someone who has spent most of his life thinking about cognition and intelligence?
Why does this matter? Well, if there are moral judgements we'd like to make around animal welfare, human welfare, and even artificial intelligence welfare, these should depend heavily on what philosophical stance we adopt with regards to consciousness. Suffice it to say, the stakes are high. As I've said before:
At my end, identifying phenomenal consciousness with a phenomenal field feels intuitively obvious – that there could be no other ground of being, and that cognition of the kind which Eliezer might identify with value is but one particular state which might be rendered within this field. I've tried to articulate this informally on Twitter:
I think this makes sense from both an evolutionary and computational perspective. What are these phenomenal fields actually doing? It seems to me that the visual and somatic field serve the purpose of binding together sparse sensory impressions into a unified world simulation. Most, if not all of the valence – i.e., most of that which I value – is concentrated in the somatic field. This somatic field valence provides what is essentially the loss function and gradient descent landscape for the dual tasks of collision avoidance and maintaining bodily integrity. It's absurd for me to imagine that this is an evolutionary innovation which happened somewhere between the chicken and the human – and that chickens do not feel pain as somatic field tension just as I do.
I think Eliezer's introspection capabilities must be lacking, and that this has lead him to confusion about the source of value within consciousness – or at least I think he must not have investigated his own phenomenology proportional to the importance of the topic. I do think that the phenomenal fields as I describe them are relatively easy to observe – but maybe that's just me. I also do not think that they disappear in the absence of the kind of cognitive reflectivity Eliezer describes.
Pragmatically, I have claimed elsewhere that I think a fat line of ketamine should be enough to reversibly melt away many layers of cognition while leaving the visual and somatic fields – the qualia – intact. I should also acknowledge that argument-from-ketamine feels at least somewhat intellectually lazy, so I'll also claim that insight meditation practices should also lead to the true ground of consciousness. As Daniel Ingram says, in Mastering the Core Teachings of the Buddha:
That said, if your timelines are short, ketamine takes only five minutes to kick in – so this may provide a more pragmatic option than hundreds of hours of meditation.
Warning: The above line is about 50% tongue-in-cheek. I feel a responsibility to note that ketamine is a substance which some people may find highly addictive.
Phenomenological variation as the source of philosophical differences
I think the blogger Scott Alexander takes a similar view on phenomenal consciousness to myself. I'd like us to take a look at something he had to say recently, in his post, The New AI Consciousness Paper:
Personally, I feel some amount of discomfort at the prospect of studying phenomenological differences which might be used to outgroup people; for example, I know a number of people who actually do have aphantasia, some of whom are quite sensitive about it. Dhabi Ibn Musa, author of the website Spiritual Rationality, handles this topic with what I suspect is an appropriately dry pragmatism. From his page on somatic phenomenology:
At the same time, I think that given that people like Eliezer want to stake moral judgements on their opinions about consciousness, the stakes are high enough that this topic is worth exploring. My primary questions are as follows. What makes the field-like nature of phenomenal consciousness difficult or unnatural to observe for some people? Or, more concisely, what makes phenomenal consciousness feel like the true ground of being?

Phenomenological shifts as the source of experiential clarity
I happened to be staying with a friend in Oakland at the time when Guy published his post. Another friend of mine, Sasha Putilin, was also attending Inkhaven, and invited me over for the afternoon to give a talk about my research. I took the time beforehand to sit down and catch up with Guy.
We wound up discussing our mutual experience of a strange phenomenological episode which might be what the meditators call stream entry, or sotāpanna – the first of four stages of enlightenment as described by the Pāli Canon. From Mastering the Core Teachings of the Buddha:
I recorded our conversation and will include a transcript. I include this here because I think this is an example of the type of phenomenological phase transition which can change the felt sense of the structure of consciousness in a way which is relevant to our preceding discussion. I was also impressed by Guy's observational skills; he describes the raw phenomenology in a candid manner which I think should be accessible to the average reader, and without making dharma jargon too load-bearing.
Guy's experience
Guy described the context leading up to his breakthrough. In 2012, he was 22 or 23, and from reading the The Motivation Hacker developed an interest in lucid dreaming, and reading LessWrong's Litany of Gendlin kindled an interest in focusing. He also developed an interest in meditation.
The context may be unclear from the transcript – I'm wishing we'd filmed a video. Guy is gesturing at different parts of his world simulation and describing which parts of this were identified as self, and which parts were identified as other. Beforehand, the self was identified with the somatic field and the parts of the visual field containing the body, and the other with everything else. Afterwards, these two things were not felt as separate anymore – they were the same type of stuff – and now the sense of an observer was positioned in an unfamiliar place behind Guy's head.
I was very interested in why exactly this state of affairs was described as more pleasant. Perhaps once it's easier to expand attention into the phenomenal fields themselves, this facilitates stepping out of the contracted attentional habits associated with trapped cognitive patterns? We'll unpack this idea more later in this post.
My experience
I also found Guy's description of the visual field as becoming more high-def particularly fascinating, as I've experienced eerily similar phenomena while using psychedelics – as well as much earlier in life when I'd had my own strange experience. I began telling Guy my own story, first explaining the events leading up to my own breakthrough. I was heavily bullied in the school system – and as an adult, despite working a chill job in a decent city and spending most of my time around kind and nonjudgemental people, I was still extremely anxious, and struggled to reset my trapped priors around social paranoia.
My working model of what cannabis does phenomenologically is add a little bit of noise to subjective experience. This seemed to help facilitate randomised breaking of thought loop patterns. My attention would expand out of the loop and into the actual phenomenal fields, which would contain a brief afterimage of what had been going on previously – maybe about 250 ms or so worth of thought loop content. This was just enough for me to observe what had been happening from the outside, shut down the process, and memorise it so that I could pattern match against it in future.
The visual field transformation was hard to describe. I think the difference between a regular lens and a fisheye lens should only be taken as analogy for the structural transformation which occured within my visual field awareness. Any image is ultimately just a projection of something more complex down onto a two-dimensional Euclidean plane, which entails some amount of geometric compromise – for example, straight lines may become curved. If the reader is interested in further exploration into the geometry of the visual field, I will refer them to the computer vision researcher Steven Lehar's writeup on conformal geometry.
Perhaps what happened was that my attention was habitually contracted either into my own thoughts or into a small region around the center of my visual field – and the wide-angle fisheye lens effect is one way of describing what it feels like when attention expands all the way to the edge for the first time.
For what it might be worth, while I was writing this, I described my own experience to my friend – who immediately recognised the fisheye lens effect. His candid description:
Awakening or depersonalisation?
Personally, I'm reluctant to specifically label either of our experiences as "stream entry", preferring instead to engage with the phenomenology on its own terms. That said, I do think our respective experiences are comparable to common descriptions of stream entry as a shift in baseline perception – including such features as dissolution of self-view – though I should mention that the model outlined in Mastering the Core Teachings of the Buddha also expects a cessation event as a relevant signifier. I guess if this happened it's possible neither of us noticed it. The core point I'd like to make is that such unusual states are real, and that members of various contemplative traditions have been observing and attempting to study them for thousands of years, and that academia is just starting to pay attention too.
I'd like to refer to the paper, Clusters of Individuals Experiences form a Continuum of Persistent Non-Symbolic Experiences in Adults (Martin, 2020), a cognitive psychology study of 319 participants from a variety of spiritual or secular backgrounds reporting persistent changes to their experience. Some key points:

Carmen's experience
I don't want to get too sidetracked. For the purposes of this post I'm less interested in classification of experiences than what clues the changes to the structure of experience might provide to what's going on. As I asked before, what makes the field-like nature of phenomenal consciousness difficult or unnatural to observe for some people?
There's a classic Twitter thread by someone called Carmen, describing her own phase transition complete with clear descriptions of attention as a field. I think these are very high quality observations:
Witnessing the phenomenal fields
I don't think Carmen's descriptions of ocean waves, eddies, and whirlpools are at all metaphorical. I believe the key word here is bifurcation. If you imagine the attentional field as an invisible vector field overlaid over the phenomenal fields, which guides the flow of attention and awareness, the eddies and whirlpools which she describes are places where the flow of attention has bifurcated from the field at large, forming looped or knotted structures which persist over time.
Animation of the Hopf bifurcation, in which a critical point transforms into a limit cycle. Imagine running this backwards – perhaps that would be what dissolving a mental construct looks like. Video by Robert Ghrist on YouTube. For additional background, I recommend reading up on vector field topology.
One may learn to dissolve such structures through meditation – or shortcuts may be taken using drugs like cannabis, ketamine, and 5-MeO-DMT – and in the process of doing so observe their true structure. Such structures might include a wide variety of mental constructs – from smaller thought processes associated with specific semantic content to much more totalising, deeply entrenched ones like the sense of being a person or possessing a self.
The striking structural transformations associated with stream entry may simply be the side effect of dissolving one or more of these larger, load-bearing structures – reducing global tension and freeing up attentional resources to flood back into the phenomenal fields at large. This in turn may help facilitate further dissolution – converting more and more psychological turbulence into laminar flow.
Conclusion
We shall now revisit Eliezer's claims. As he puts it in his 2014 facebook post, he does not believe there is experience without some kind of self-referential cognitive process:
The accounts I present here suggest that this is pretty much completely backwards. Guy, myself, and Carmen all experienced a very similar phenomenon – a large-scale reduction of the kind of cognitive processing which Eliezer identifies with consciousness – all while subjective experience persisted and even became more vivid. Guy described his visual field as more high-definition; mine expanded into unfamiliar wide-angle geometry; and Carmen learned to observe her attentional field in great detail. Carmen's key insight is that you might not be able to observe the field-like structure of consciousness before this happens because there is too much attentional bandwidth being monopolised by cognitive processes.
Straightforwardly, I suspect that identifying consciousness with a quote-unquote cognitively reflective, self-modely thing must be the position of someone who has never gotten out of the car, as we say – though I'd need to actually speak with him before I can be confident in this. I believe that if he did, it would be clear that cognitive structures such as what we call a self are merely arbitrary constructs within consciousness, and when they are dissolved, neither consciousness or its self-reflective qualities blink out with it. The visual and somatic fields retain their qualia, and the implication for chickens and pigs is that they likely have qualia too.
I'll acknowledge that my claims are based on only a handful of observations – sample size three – so I can understand if the reader remains skeptical. I'll reassert that the Persistent Non-Symbolic Experiences paper documented similar patterns in interviews across 319 participants, and that contemplative traditions have been cataloguing such transitions for thousands of years.
If there is one thing that I'd like the reader to take away from this post, it is that the structure of consciousness can be investigated empirically. If you remain sympathetic to Eliezer's perspective, but you have also experienced such a state transition yourself, even if it was temporary – then I think you should consider updating on this. If you have not, I think you should fact-check my claims, and consider doing some phenomenological investigation of your own.
Implications for digital consciousness
As I mentioned earlier, the philosophical stance we take on consciousness has implications for artificial intelligence welfare, so I should cover this too. I think that whether or not someone experiences the structure of consciousness as a field may be the kind of thing which could influence someone's preferred theory of consciousness. Deciding whether or not phenomenological reports provide accurate information about the physical structure underlying them represents a jump from phenomenology to ontology. Identifying consciousness with something more continuous domain than discrete domain – analog rather than digital – may in turn make physicalist rather than computationalist theories of consciousness more appealing.
Physicalism being true would imply that digital minds do not possess qualia which are related to their computational structure, and instead we must consider what qualia might relate to the structure of the physical substrate they run on. That said – as Ethan Kuntz reminds me – if the phenomenal fields have a diffraction limit, then this would prevent us from making claims about their continuity based on observations from the inside. Pending experimental investigation, this line of debate may have to remain an undecidable crux. At present, I'm most interested in exploring claims based on simplicity priors.
If someday we are forced to declare stalemate in the debate of physicalism vs. computationalism, a more pragmatic question may be how people with different ontologies can solve coordination problems together. If this is of interest to you, I hope to present future debate relating to this topic in a series of upcoming posts. Stay tuned.
