Dream Time

Daniel Dennett is quite annoying. His view of consciousness is completely absurd, for example. I’m not going to defend my position here because this isn’t exactly what this post is about.

In case you don’t know, Daniel Dennett is a major analytical philosopher, the English-speaking tradition of philosophy dating from the late nineteenth century CE with the rejection of Hegelian idealism, continuing today and apparently also including Polish philosophers for some reason. Bertrand Russell is a good example. It was once described in ‘Radical Philosophy’ like this: a Heideggerian says something like “Die Welt weltet”, and analytic philosophy comes along and says “Where is this Welt, and when exactly did it start welting?”. It is actually mainly my own background and I have a lot of respect for it, partly because I think postmodernism is a good way of making excuses for how things are politically and socially without coming up with a solution to them, and that comes out of the continental tradition. I’d also distinguish analytic philosophy from other viable philosophical approaches taken by anglophones such as that of William Blake, who is unsurprisingly an outsider and apparently linked to the Muggletonians, about whom I know very little. Sarada is the expert on Blake, but for what it’s worth I think of him as an English Romantic. I don’t know if that’s fair.

Recently, Dennett was involved in a movement referred to as the “Brights”, whose aim was to further metaphysical naturalism. Metaphysical naturalism is often treated as if it’s synonymous with atheism, but in fact it’s a specialised form of atheism which is radically different, for instance, from Marxist atheism and the South Asian Samkhya and Carvaka. I had a conversation with a White bloke the other day who was atheist because of karma, a view also found in South Asian thought. The basic idea there is that because karma is a universal law governing the working of the Universe, there’s no need to suppose that God exists. Although I’m theist, I do find this interesting on an intellectual level, mainly because it’s so unlike metaphysical naturalism but still strongly atheist. Metaphysical naturalism is the idea that only natural forces and laws operate in the Universe, i.e. there is no supernatural realm and therefore no God or other deities. Obviously I don’t agree with this, but that isn’t why I find Dennett annoying.

The Brights were founded by Dennett and Dawkins, among other people whose names don’t come to mind right now. Other metaphysically naturalistic atheists, such as Christopher Hitchens, have criticised the name as appearing to imply intellectual superiority. It reminds me a bit of the stereotypical Mensa attitude. To be fair, I’m not sure this was the intention so much as an attempt to come up with a positive-sounding name. Brights use the word “super” to describe people such as myself who have supernatural and/or mystical elements as part of our view. This actually makes me sound like Wonder Woman or something, so it’s okay really. Nonetheless, the Brights believe themselves to be right and us to be wrong. It isn’t an unusual position to see oneself as correct by contrast with others whose opinions differ, so that is also fine.

One of Dennett’s more bizarre positions is that lucid dreams are not experiences. This strikes me as a kind of ideological commitment resulting from it being a logical conclusion of his other views about consciousness. However, it’s also an elaboration of another, simpler position of his with which I actually do agree, in a sense: that dreams are not experiences in general. I do differ with this view but also think it captures something significant about the nature of consciousness, particularly wakefulness. Looking at them from a position of being awake, it seems to me that dreaming could well represent the wakeful consciousness attempting to make sense of the “junk” present in one’s mind on waking. There are some reasons why this may not be true, but others which are hard to reconcile with it not being so. For instance, someone I know once dreamt that she, note the tense in this phrase, has to cry three tears to save a toad’s life, and I could hear her trying to do this several minutes before she woke up. On the other hand, I was once dreaming while the radio was on and the sequence of events on the radio is time-reversed in my dream. The dream ends with something happening on the radio which in waking experience happened before something which starts the dream, which can be explained if dreams are false memories created during REM sleep.

The idea that lucid dreams are not experiences is kind of arse-about-face. It’s a conclusion Dennett is forced into due to his expressed view of consciousness which is counter-intuitive to me, and I’d think to most other people. There is an odd phenomenon in consciousness where immediately prior events are “re-written” by memory. For instance, MP3 files when played back often have periods of silence in them before loud notes which the listener doesn’t notice because they’re eclipsed by the slightly later event. Dennett uses a similar illusion called the “phi phenomenon” where lights of two colours flashed in succession leads to the perception that a single light is moving back and forth and changing colour. He offers two explanations for this, which he calls “Orwellian” and “Stalinesque”. In the Orwellian hypothesis, like Winston’s experience with the fingers (or Picard’s experience with the lights in ‘Star Trek’, which is a direct steal), perception is revised after the fact of being experienced. Stalinesquely, the forthcoming experience is revised before reaching consciousness like a show trial whose verdict is pre-decided. These two versions of what happens don’t require any difference in the model of what’s going on in the brain. The only difference is in when the perception becomes an object of consciousness. The claim is then that the reason there is no difference between the two is that this account of consciousness as emerging at a certain point is an error based on the legacy of misunderstanding consciousness as Cartesian – that is, that living humans consist of two substances, the soul and the body, whereof the former is conscious and dimensionless and the latter occupies space and is not conscious, with the two interacting, according to Descartes within the pineal gland. Dennett believes that we are still too attached to this kind of account, although we don’t literally believe it any more, and that consciousness is not a special, circumscribed state, has no subject of experience (I have sympathy with this bit) and is actually the flow of information from place to place.

Applying this to non-lucid dreaming, information flow would occur on waking. With lucid dreaming, we only have illusory choice and experiencing in the moment according to this account, which also applies as far as Dennett is concerned to waking life. Dreaming and lucid dreaming are primarily useful illustrations of his general theory here rather than objects of study themselves.

Obviously I think he’s wrong. He also casts doubt on the existence of qualia, which are the essential qualities of experience whose existence cannot rationally be doubted. Qualia, put another way, are what people refer to when they say things like “your red might be my blue”, which captures the notion well but doesn’t actually work in detail because of the network of experiences and how they relate to one another. It’s important to decide what are and aren’t qualia, because once one declares something as a quale it’s placed beyond question and that restricts possible arguments. For instance, Nkechi Amare Diallo could claim that her Black identity is a quale, at which point White people identifying as Black suddenly becomes sanctified in some realm beyond criticism. I actually do think the mental perception of the possibility of becoming pregnant is a good example of a quale which is not intuitively so, because it sometimes leads to radical departures of opinion regarding the ethics of reproductive choice, and that does in fact correspond to “no uterus, no opinion” as the position is sometimes rather crudely expressed. However, the existence of quale cannot be doubted, and if someone is led into the position where they can make such a claim, it comes across to me as a weird ideological commitment to an untenable position rather than something which can be attached to an account of consciousness.

From wakeful experience, we tend to perceive dreaming as something which occurs while we’re asleep, and individual dreams as prospects which occur in the future of our wakefulness before we fall asleep and in the past of our wakefulness when we have woken up. With closer examination, we might conclude that dreams are not experiences but attempts by a wakeful mind to make sense of the clutter present in our minds when we awake. Although I think this is incorrect, it does work well as an illustration that the chronology of dreams is not what we might assume. Lucid dreaming is said to be encouraged by always recounting dreams in the present tense. This is somewhat confused by the fact that not all languages have a present tense, and this raises a further question: are there languages which have a way of expressing dream time?

Before I answer this question, I want to outline my understanding of states of consciousness. I believe it makes sense to say there are six states of consciousness: wakefulness, dreaming, dreamless sleep, hypnosis, meditation and Ganzfeld. There’s also a very strong tendency to prioritise wakefulness above the others, to the extent that it’s seen as the only realistic state of consciousness and the state which dictates the nature of time. Dream logic is not seen as proper logic. A friend of mine recently observed, interestingly, that although I had recently dreamt about the King, that didn’t mean there wouldn’t still be Queen dreams. My own attitude towards states of consciousness is rather different. I believe that several or all of those states are of equal, or perhaps incommensurate, status. The list I’ve just made was from a wakeful state. It’s equally possible to dream of a completely different list. I’m not convinced that hypnosis is a valid state of consciousness but I do believe it’s neither dreaming nor dreamless sleep. There are “state” and “non-state” views on hypnosis. The state view is that a hypnotised subject has entered an altered, more suggestible state of consciousness, which is supported by their alleged inability, in some cases, to recall the events which took place during it. The non-state version is that hypnosis is a form of role-play in a kind of theatrical setting, which doesn’t just apply to stage hypnotism but also the likes of hypnotherapy. That idea is not supposed to contradict its efficacy as a therapy, incidentally. Ganzfeld is the other state which could do with a bit of explanation. This can be introduced by relaxation and sensory deprivation although it also occurs at one’s bidding, perhaps with a bit of practice. It may not may not be a healthy state.

Insofar as each of these is a valid state of consciousness, none has priority over any others. Each has unique features. As I’m mainly contrasting dreaming and wakefulness here, taking them equally seriously, the wakeful mind can have a view of dreaming that is either the detritus of dormancy or a sequence of experiences which occur between successive experiences of wakefulness, but this is only the view of the waking mind and is no more valid than that of dreaming. There is still a relationship between dreaming experiences and the senses, for instance because a cold night might be associated with dreaming of the Arctic or because some experience one had the previous day influences the dream. From the perspective of dreaming, wakeful consciousness influences one’s experience but there are oddities about its temporality because with dreams of any length, it can often be difficult to locate a moment when the dream begins and, as I’ve said before, some of my dreams involve things like “having always sat on the roof”, i.e. my dream is of climbing out of a bedroom window onto the roof just like I always have for years. From a dreaming perspective, whatever waking life makes of them, dreaming consciousness is very different in terms of the passage of time and even if it turns out that dreams are squished-up false memories of stuff happening immediately before waking from a daytime perspective, this has no more or less validity than whatever the dreaming mind thinks of wakefulness.

Given all that, this is the question I am mainly interested in answering here: how do we refer to dream time? English uses the present tense to refer to “tenseless” things, such as saying that “one plus one is/equals two”. We don’t usually say “one plus one used to equal two” or “one plus one will be two next Thursday” unless we’re trying to make some kind of rhetorical point about eternal verities. I have said in the past, from a waking perspective anyway, that the events of dreams should be referred to in the aorist. This is in fact a somewhat inaccurate way of describing what I’m doing when I seem to use the present tense.

The word “aorist” originates from the Ancient Greek “ἀόριστος”, which breaks down as “ἀ-” – not – and “όριστος” – definite. In other words, “indefinite”, “undefined” and also simple – the unadorned, plain form of the verb. In English, we might identify this with the simple present indicative except that in English this usually puts an S, an “-eth” or “-est” on the end, so it isn’t usually unadorned. As an ahistorical, perhaps an aorist, word, it seems to work quite well as a way of describing events which do not occur in the waking passage of time, but in fact the Ancient Greek usage is to refer to the past. It’s used as a narrative tense, so it does make sense if dreams are retold as stories to use the aorist, but in certain circumstances can also refer to the present or future. It’s also worth mentioning that there is aspect as well as tense involved here. Aspect is how the action described by a verb occurs over time, i.e. whether it’s a one-time short term event, a repeated action or a continuous one. For instance, “I rowed” and “I sowed” might involve grabbing the oars just once and sculling briefly and putting a single seed in the ground, or they might refer to rowing across a river or walking across a field broadcasting a full bowl of seed. English seems to have lost the ability to distinguish easily between these, but many other languages actually focus more on that element of time than on tense. Hence aspect is still relevant to dreaming as experience, or perceived experience but tense may be misleading.

Sanskrit also has an aorist, which is relevant because it happens to be used to discuss consciousness a lot. In fact I almost used the word “samadhi” to describe what I called “meditation” just now. There are two aorists in Sanskrit, one which is simply preterite indicative, like our own simple past, and an injunctive mood, which is also found in Homeric Greek, which could be used as an imperative or subjunctive, usually for prohibitions in later Sanskrit.

Hence the problem is that although there is something out there called the aorist, which is not in any case present in English, it actually tends to express the past although it technically needn’t and the literal meaning of the word “aorist” is not perfectly reflected in the actual meaning of the word. From the perspective of wakefulness, I would want to express dreaming experience as occurring in a kind of abstract time. Imagine a three-dimensional line graph. The space within that graph could be said to be located in a particular place in the sense that it might be on the page of a book or a computer display, but there need be no region of the Universe consisting of a graph, which can in principle be visited. Time and space in dreaming are virtual. Events can be located relative to each other temporally only within the dream, but need to be referred to outside of it, but referring to them in the past tense doesn’t do them justice.

Calling this post “Dream Time” makes it sound like a reference to the idea Australian Aboriginals are said by Western anthropologists to have about the primordial state of the world, but as usual it’s important to examine this critically. If it turns out that the kind of wakeful consciousness we have today in the West is highly contingent, maybe our lives are surrounded temporally by a sleep, not in the sense of absence of consciousness but as a different kind of consciousness. I know very little about this and feel it would be culturally insensitive to say too much about it, as well as inappropriate for the cultural and environmental milieu I live in, but the term itself suggests to me an entirely valid concept of a kind of timeless eternity out of which our wakefulness condenses. I have no idea whether this is what anthropologists mean by it or whether it even exists in any Australian Aboriginal culture, but it does make sense although it might give dreaming unwarranted priority. At this point I could of course read what Wikipedia says about it and pretend I know what I’m talking about, but that doesn’t do it justice.

Behind all this while I’ve been writing is awareness of a particular form of dementia called Lewy Body. This is associated with Parkinsonism, and involves the mixing of dreaming and wakefulness. Although it would seem insensitive to regard this as anything other than a pathological state, it is interesting that this occurs towards the end of waking life. We tend to think of dreaming and wakefulness as sharply differentiated, although when I had B12 deficiency early signs of my psychosis there was some such mixture. Prisoner’s cinema, Charles Bonnet Syndrome, phantosmia and possibly some forms of tinnitus and hearing voices also seem to have things in common with this. Prisoner’s cinema is more like Ganzfeld, and in fact it leads me to wonder whether states of consciousness are to each other like different gears on a car, with Ganzfeld intermediate between dreaming and wakefulness.

People have been known to enter a state of meditation as a prelude to their death. More often, the state of mind immediately before death as monitored by instruments resembles dreamless sleep and this continues immediately after death, with a sudden flash of activity a few minutes later. Once again, it may be inappropriate to refer to these phenomena temporally, as any subjectivity may not experience them in this manner.

This post, I hope, will make a good companion to tomorrow’s, written on International Yoga Day.

Farewell Wordle

Like a lot of other people, I’ve been playing Wordle every day. This is the online “Bulls And Cows” game similar to the Mastermind peg board game where you have to guess a five-letter word in six goes. I hardly feel it’s necessary to say much more, but you might be reading it years after it’s fallen from popularity, so I will explain it, possibly for the second time since I think I’ve done this already.

Here goes then. Wordle uses a different five-letter word each day. When you type a word, it colour-codes the letters according to whether you have a completely wrong letter (grey), a right letter in the wrong place (yellow) or a right letter in the right place (green). There’s also a hard mode, which only allows you to type letters which haven’t already proven wrong. This isn’t in fact so much harder than slower, although it’s possible to get more right answers if you are allowed to put down more letters you know are wrong because you don’t then have to think of words with absolutely no letters you haven’t tried before.

Now by most people’s standards I am really not good at Wordle. I often don’t manage to guess at all, and up until November 2022 I was worse than average. It made me feel, in fact, that I’m in cognitive decline in some way because most people seemed to do better than me. Wordle has had a time limit on it since it started, allowing something like 2500 words altogether as answers with a much larger pool of words which are allowed but are not answers. A while back, probably on this blog, I did some research into the answers, since at the time there was a complete list of them as they were initially planned to be. I didn’t actually read these answers but it was difficult to handle the text without glimpsing them. What I actually did was to go to a web page listeing all the solutions, which incidentally were present in the source code for the web page for Wordle itself, and I imagine still are, although even there they’re hidden, select all the text without looking and ran it through ROT-13. This is a trivial coding method used to conceal spoilers, where each letter is shifted by thirteen places as if the alphabet is in a wheel, so letters in the second half of the alphabet end up in the first half and vice versa, meaning that A becomes N, B becomes O, N becomes A, O becomes B and so on, making it harder to read. I then selected the list on the page, did tallies of the positions and frequencies of each letter in each position and ran it through ROT-13 again. Yes, it did occur to me that if I knew contemporary programming languages this would’ve been a lot better and I’m guessing it would’ve worked really well in Perl, but that’s just a guess. The result was that the most likely word to come up seemed to be “POINT”. However, given no knowledge of which letters are placed where, the best guesses are sometimes said to be “CRANE” and “SOARE”, and there are also other possibilities based on other criteria. Many people guess “ADIEU” first, which makes some sense because it has four out of five vowels.

My strategy for a while, which I doubt was logical, was to use the word “POINT” over and over again. This gave the same mean probability over the whole list. However, I later changed this to guessing arbitrary words, on the grounds that some would be closer to the correct guess than average and others further. This is kind of what happened, but I didn’t expect it to be so dramatic.

From November 2022, Wordle’s rules changed. The only one I can consciously remember is that they eliminated every plural ending in S or ES. This does mean the number of words ending in S would be smaller, although how much smaller is another question. It also seems to mean fewer words with a penultimate E, although this may not be so because, for example, French passives often end in “EE”, such as PAYEE and MELEE (apparently that’s not a passive, but you get the idea). The other rule changes are – ah, apparently that’s the only change. You wouldn’t think it would make that much difference, but I do know that since that point, there’s a much bigger split in the number of guesses I have to make to get the right answer. Nowadays, there’s been a greater tendency to fail completely or get it first time. I think I’ve fairly got it in one four times now, although on another occasion I saw Sarada’s answer and put that down, which was pretty pointless but maybe a bit compulsive.

The point of this post is to try to get to the bottom of why I’m managing to get so many guesses which are right first time. Since the rule change, the previous frequency of letters in specific places has probably changed. This makes one hypothesis less likely to be correct. I had thought that I could’ve subconsciously learnt the list by studying it after it had undergone ROT-13, but the list having changed, this is probably not the explanation. If it had been, I would’ve had more guesses right first time over the period between deciding to guess arbitrary words and the rule change, but in fact over that period I didn’t get any right first time. It doesn’t explain why I’m also failing more often than before either. Hence I’d reject this hypothesis.

I think there is a possible clue in a slightly similar experience I have. Like a lot of people, although I don’t seem to be able to get my head round a banking app, I do have a keypad for using with online banking. This is probably something everybody knows about and has, if they’ve got a bank account, but if not, here’s an explanation. A few years ago, I got a calculator-like device in the post from my bank which I assumed for quite some time was an actual calculator which they’d for some reason given me for free. In fact you’re supposed to slip your bank card into it and put in your PIN, and it produces a different eight digit number every time which I presume it would be a security risk to put here. This number has a a different form depending on what you’re doing, e.g. transferring money, signing in or retrieving your customer number. Incidentally, have I just explained something everyone already knows? I have no idea. Anyway, every time this thing produces a number, it somehow seems “right” to me, and if I were to be given a random eight-digit number having just entered my PIN, I think I would know if it was correct or not. I have no idea (once again, maybe as usual) why this is. This hunch can, however, be tested. Unfortunately, it can’t really be tested without becoming a potential breach of security, which is a bit irritating.

The keypads are interchangeable, at least for the same bank – I have no idea if they work if your card is put into a different bank’s reader. Thus they don’t store any personal information. I presume what they’re doing is taking the customer’s PIN and their card number, or possibly some other number associated with the account or stored as data on the card, and combining the two to generate an integer between 10⁸ and 10⁹, which can be tested against some number associated with the account. For some reason, although I have no idea how it does this, I get the impression that I can tell that there’s something “right” about the integer in question. I may be wrong about this of course because there’s massive confirmation bias.

What I think may be happening here is that for some reason I’m able to judge subconsciously the process whereby the numbers on the keypad and the answers to Wordle are arrived at. I don’t know how I do this. I do know it doesn’t work very well.

It’s even possible that the method used to generate the wordlist for Wordle is subconscious for the editor as well as the person trying to guess. It is, however, odd that it didn’t work before and now it does, apparently coinciding with a trivial change in the rules.

Wordle has been the first thing I do when I wake up quite often, so it’s possible that my brain is not in a usual waking state when I do it. This morning I actually had a dream about text, where I program a computer to produce the string “Super Siouxsie” in pseudorandom positions all over the screen. I then woke up and was able to produce, in a small roughly circular position in my visual field, a hallucination of various lettters. I’m guessing that most people can do this too, although it does feel a bit like an abuse of my brain to force myself to have visual hallucinations just for fun. However, this took place immediately before I did Wordle, and it occurs to me that having a brain apparently full of letters may be connected to my first-time correct guess. It’s been suggested to me by [po] that it may be a form of sleepwalking, and this makes some sense, but I think it’s more that my mind is in an unusual state when I’m doing Wordle. One way of providing evidence for this would be to time the gap between waking up and playing. If the interval tends to be shorter when I get immediate right answers, that suggests that I am in some way in a different state of consciousness when I do it.

Anyway, I’m a bit freaked out by all this and on occasion Wordle presents absolutely no challenge to me, and on others it presents a literally impossible challenge, so I’ve decided to give up because it isn’t a challenge to my conscious mind. There is no strategy which helps me to win now It was fun while it lasted.

States Of Consciousness

This was almost about near-death experiences (NDEs), and may still go on to include them, but primarily the task I’ve set myself today is to describe states of consciousness and their possible relationship with reality. This has been of interest to me since soon after I started meditating, which must have been over forty years ago, and my thoughts on the matter are not necessarily particularly up to date because I’ve thought about them in a fairly piecemeal manner. This may in fact be the first time I’ve actually expressed myself clearly on the matter.

Okay, so there are maybe about seven clearly separated states of consciousness which may blur into each other. These are: wakefulness, REM sleep, NREM sleep, samadhi (meditation trance), dreaming, hypnosis and Ganzfeld. Of these, hypnosis may not exist, something which I’ll cover later. Ganzfeld probably needs some explanation. The Ganzfeld Effect is what happens when one is deprived of sensory stimulation, as in a floatation tank or with special blindfolds in an anechoic chamber, and involves the projection of hallucinations into one’s subjective space. As such, it seems to resemble Charles Bonnet Syndrome. More on that later. Each of these is characterised by particular brainwave patterns. There are also intermediate states such as sleep paralysis, lucid dreaming, false awakening, near-death experiences and dementia with Lewy bodies. My own experience of B12 deficiency suggests that it can be quite similar to the dementia, and schizophrenia and delirium might also belong there. Therefore, a bit like the gender landscape, it might make more sense to think of consciousness as a plain with peaks representing the different states.

Most of the time I’m focussed on the distinction

Most of the time I’m focussed on the distinction between dreaming and wakefulness. I try to avoid prioritising one of these states over the other, because I think that phenomenologically both are equally valid and represent different relationships with reality. I also talk about dreaming in the present tense, although this is substantially because I don’t think English has a tense which can refer to dreaming accurately. Dreams are timeless in the same way as numbers and abstract concepts are, so if there’s a language with a way of expressing verbs timelessly, so that for instance the “is” in “two plus two equals four” is not in the present tense, I’d be using that method. It’s also supposed to make lucid dreaming more likely if one does this. I mentioned yesterday that Dennett has the view that dreams are not experiences but false memories. That is, on awakening one has a particular brain state which the waking mind interprets as consisting of apparent past experiences which occurred after falling asleep. But it’s the waking state that perceives it this way. Because dreaming and waking are equal, this fact, being a product of wakeful consciousness, is no more valid than dreaming experience.

Years on the Halfbakery ideas bank, have convinced me that ideas are discovered rather than invented, and that discovery and invention are the same thing. Hence at some point in the distant past people discovered the wheel. This makes sense, for example, when one thinks of Charles Fort’s idea of “steam engine time”. There is apple blossom or cherry blossom time, when all the trees of a certain species come into blossom at once even if they’re thousands of kilometres apart. Similarly, at least three civilisations have independently developed the steam engine because it was the right season for doing so. The various pieces of the jigsaw fell into place and the shape of the gap remaining became apparent. Likewise people come up with remarkably similar novels without apparent connections, such as possibly ‘The Time Traveler’s Wife’ and ‘Slaughterhouse Five’ or ‘The Hermes Fall’ and ‘Lucifer’s Hammer’. Likewise, dreams are “out there” waiting to be had, perhaps only by one particular individual. Hence they don’t happen on a particular night but one wakes up having discovered a dream which was always, and will always be, there, though more strictly outside spacetime, wherever numbers and steam engines dwell before we open a conduit to them and our world. Somewhere sub specie æternitatis, Everyperson is having tea with the Queen. The reason lucid dreaming, conscious control of dreaming, is important is that it amounts to Heaven, whereas nightmares amount to Hell.

I don’t want to make this post entirely about dreaming, although I have more carefully developed ideas about that state than others. That said, there are supposed to be tests for dreaming, one of which I try in a recently remembered dream. I took a shard of mirror and looked at myself through it, and not only was part of my face clearly reflected in it but it moved appropriately when I held the shard at different angles. This detail has caused me to doubt that the tests are reliable, and it also amazes me that my brain is able to produce an image that realistic, although I’ve successfully done that in Ganzfeld.

I will say just one more thing about dreaming and wakefulness. There are mixed states where both are involved. For instance, when I had B12 deficiency I began to enter a psychotic state involving phantosmia and anosmia. I constantly hallucinated the odour of peppermint and sometimes confused dreams and wakefulness when I first woke up in the mornings. Objects and people in my dreams appeared in the room I was sleeping in (which was the living room incidentally, but that’s another story). This is similar to dementia with Lewy bodies, where older people cease to distinguish clearly between dreaming and waking life. Bearing in mind that these people’s lives are approaching their end, it raises questions about near-death experiences. Finally there’s Charles Bonnet Syndrome, where deteriorating vision leads to patterns or even detailed scenery involving people and places. This is similar to the phantom limb phenomenon in my opinion, and also to tinnitus and hearing voices in some ways. All of these are somewhat dreamlike.

They’re also similar to Ganzfeld. This is a state of consciousness which results from uniform sensory stimulation or the lack of stimulation entirely, and is sometimes sought by people in floatation tanks and anechoic chambers, as mentioned above. The brain amplifies neural noise and turns it into complex visual impressions, I would imagine very similar to Charles Bonnet Syndrome. It can also be done using white noise, which I’ve tried myself and found I could hear music in it after about half an hour. It also constitutes a second way into lucid dreaming, so I’m told, because apparently if you lie still in bed in a cold dark room for at least half an hour you will begin to have these impressions. I don’t know how easy other people find lying still, or lying still without falling asleep, and I know that I’m supposed to be genetically predisposed to moving around a lot during sleep and to having restless legs, so it’s unlikely that I will find a way in this way. There is a Tibetan Buddhist practice known as mun mtshams (I cannot currently write this in Tibetan script but it might be མུནཚམྶ​), involving shutting oneself away in the dark alone as practice for dealing with བར་དོ and realising  འཇའ་ལུས་, thereby, I presume, avoiding reincarnation. This is rather reminiscent of the use of lucid dreaming for a similar end.

And that brings me to samadhi, समाधी. I should point out at this point that my own opinions and experience of समाधी seem to be different from what other people say about it. This is the meditative state of Raja Yoga, and I expect Sarada will have things to say about this. My understanding of how to enter this state is that it tends to be easier in certain asanas, such as Padmasana of course but also others such as Sukhasana, then one practices Pratyahara, the withdrawal of the senses, followed by focussing on a mantra or other object of thought and grasping its essence, then removing that essence entirely, leaving consciousness in a non-intentional state. I’m told that this is not what Samadhi is, and that the Christian understanding that this is in fact the nature of Samadhi is a major reason for seeing Yoga as Satanic. The fact, phenomenologically speaking, that for me it’s a state of consciousness without an object of consciousness has made me sceptical about Brentano’s analysis of mental states, where he insists that they are a number of things I do agree with, including incorrigibility (cannot be doubted) and having a number of other properties including “aboutness”, which is in fact generally considered the most important quality of mental states. This is what’s rather unhelpfully referred to as Intentionality (with a capital I, constrasted with “intentionality”) and may or may not be the same as intensionality with an S, which is to do with meaning and contrasted with extensionality. Presumably Pratyahara could also be used to enter Ganzfeld if one was so inclined. I understand that other people use the word samadhi to refer to a consciousness of unity with the object of meditation or even the Cosmos or God, and I’ve experienced that too but tend to perceive it as pathological, for me anyway. It’s unwelcome and seems unhealthy to me. In Buddhism, this state of consciousness is the last element of the Noble Eightfold Path. I can’t really do justice to all of this here, partly because I’m using words but also due to wanting to describe other states of consciousness. Because I try to balance the value of different states, the idea that this is a higher state is hard to come to terms with, but its role within dharmic spirituality has always been prized. The reason many Christians disapprove of it is that they believe an empty mind, which is how they see this, invites Satan or evil spirits in. It’s probably worth mentioning at this point that I don’t respond to psilocybin, the only psychedelic I’ve taken, so this may reflect my atttitude towards samadhi.

Hypnosis may or may not be a state of consciousness. My own view is that it’s stateless and a form of role-play, although that has a function as serious as many others in spirituality and other aspects of life. I’m also suspicious of hypnosis being misused because I think many symptoms are there for a reason and removing them outside the context of hypnotherapy would be likely to lead to the underlying cause being manifested in a different and unpredictable way. Interestingly, Sarada thinks exactly the same thing about lucid dreaming. Having said that, I do believe hypnotherapists are usually professional and take pains doesn’t happen. I used to practice hypnosis for fun when I was about twelve, quite successfully, but that was probably reckless and irresponsible, and I’ve also done self-hypnosis. An early non-state definition of hypnosis was offered in 1941 by R. W. White: “Hypnotic behaviour is meaningful, goal-directed striving, its most general goal being to behave like a hypnotised person as this is continuously defined by the operator and understood by the client”. That said, there are changes in brainwave activity in some hypnotised individuals, and the question of how it causes amnesia occurs to me.

The seventh state, which I have yet to discuss, is NREM sleep, also known as dreamless or orthodox sleep. This is in some ways the odd one out, as it seems to involve the absence of consciousness. There is no paralysis and the parasympathetic (P for Peace) nervous system is dominant during it. The EEG shows theta waves and sleep spindles, which are rapid bursts of electrical activity building to a crescendo and then declining. Theta waves occur at four to eight times a second. Delta waves are prominent. There are also K-complexes, which are the highest voltage physiological spikes of electrical activity in the human brain. I have more of these than most people because they’re associated with restless legs syndrome, but have no idea what their significance is. It doesn’t seem possible to describe NREM sleep phenomenologically because it seems to lack phenomenology entirely, but since I’m panpsychist this is either a challenge to my beliefs or means I must assert that consciousness is there, just as it is everywhere else, but in a similar way to how it would inhere in an organism with nothing analogous to a nervous system. To be honest I don’t know what to do with NREM.

On the subject of brainwaves, it’s probably worthwhile describing this kind of activity with respect to the other states. Dreaming is closer to wakefulness than NREM in this respect, hence its other name, paradoxical sleep. Theta and gamma activity is widepread and the brain stem seems to initiate activity in this state, suggesting to some that dreaming is an attempt by the conscious mind to make sense of vegetative neural processes in the absence of sensory stimulation of other kinds, which makes sense because so many dreams involve frustration and paralysis of some description. In meditation, alpha and theta waves are more active, and with habitual meditation it used to be thought there were permanent changes but recent findings have not shown this to be so. However, habitual meditators’ brains do age more slowly with respect to memory. The possibly related mindfulness is said to have a number of disadvantages, including over-exertion, ignoring intuition, exacerbating anxiety and triggering depersonalisation. It isn’t clear to me how close mindfulness and samadhi are to each other though.

Hypnosis shows more active alpha waves, but these are often used in imaginative states so it may not indicate that it’s a separate state of consciousness.

Another possible approach to consciousness is to see them as phases like those of matter, which can perhaps be shown on a graph. This has been done, for example, with meditation. Denis Postle has attempted to model the different states of consciousness on the butterfly catastrophe graph, which has four axes. Unfortunately I can only remember arousal and relaxation. Catastrophe theory has gone out of fashion nowadays because although it’s valid, there are few situations which can be reduced to only a few significant parameters. Whether that’s true of consciousness I don’t know. Even so, the idea of there being some kind of space or hyperspace with regions corresponding to different states of consciousness seems to be a good one.

There are also other states of consciousness which we may potentially have but don’t experience in everyday life. For instance, there is a case of a hiker who fell off a path in a remote area and was found alive long after he could be expected to have succumbed to exposure, and it’s thought that he may have entered an obscure state of hibernation. There is one known species of primate who does hibernate, the fat-tailed dwarf lemur. It is of course much more common in other mammals, but for humans this state could be useful for long haul space travel, so if we were ever going to do that, and we aren’t of course, it would be worthwhile looking into. Speaking of space travel, the question of out of body experiences as a separate state of consciousness arises. Is astral travel a distinct state or is it more like dreaming or Ganzfeld? Then there are NDEs. Soon after the heart stops, the brain enters a state whose electrical activity resembles that of NREM sleep, followed by a final burst of sudden activity as the neurones cease to be able to compensate for their increasingly hostile environment and lose their polarisation. That could also be a separate state of consciousness in its own right.

To conclude then, I haven’t really done this subject justice in the limited time and attention span available, but one final thought does occur. Is it right for me not to prioritise any state of consciousness over any other? Most people would probably say samadhi is a higher state than the others, but on the other hand Tibetan Buddhism appears to employ Ganzfeld as such a state, and there are also trance-like ecstatic states used in other forms of spirituality which might correspond more to hypnosis, if that is indeed a state. Whatever is the best way to arrange these, it certainly seems worthwhile to consider their relationships with each other and also with reality. I feel I’ve done this quite thoroughly with dreaming and wakefulness, but not the rest, and it definitely seems like a valuable exercise.

Neanderthal Pinhead Brains And The Sentient Internet

Stereotypically, Neanderthals tend to be presented as the classic “cave man” caricature, usually male, clubbing their female partners over the head and dragging them off by their hair, somewhat hairy themselves and of course notably unintelligent, oh, and living in caves. I’ve had a go at this stereotype and the other one about dinosaurs previously, but before I get down to things I may as well go through it briefly again.

First of all, dinosaurs are often used as a metaphor for something which is clumsy, overgrown and unable to adapt to a changing world. This really owes more to the Victorian image of dinosaurs as giant lizards than what’s known about them nowadays. Dinosaurs really got lucky, then got unlucky. The mass extinction at the start of their reign helped them take advantage of their various ecological niches, then the mass extinction at its end killed them off because many of them were very large. Many of the smaller ones survived as birds. If humans had been around at the end of the Cretaceous, we too would’ve bitten the dust.

Neanderthals are a kind of blank slate to many people onto which various things can be projected, and I may well be doing the same. Their brains were often larger than ours, but that doesn’t mean they were more intelligent. The probable cause of their brain size was to do with a bulkier body and the need for more pathways to help control and perceive that body. Whales have larger brains than we for similar reasons, although in their case that isn’t all there is to it. Nonetheless, when one considers that orang utan, gorillas, bonobos and chimpanzees are all capable of sign language, and chimps have learned to speak a few words but lack the vocal apparatus to master human speech effectively, this automatically places their “IQ” above that of the severely learning disabled. Note that I’m extremely sceptical of IQ as a concept. If orang utan intelligence is sufficiently similar to human to be assessed and rate above thirty on an IQ scale, Neanderthals are bound to be at least that intelligent. It’s also thought that human short term memory has suffered at the expense of developing language, as that of chimpanzees is far better than ours. Hence when Neanderthals come into the picture, it can be assumed safely that they would also have been capable of language and perhaps actually used it. The crucial final step in physical capacity for phonation – producing speech sounds with the vocal tract – is the position of the hyoid bone in the throat, which allows attachment for the larynx, glottis and tongue, and needs to be in a particular position to enable its owner to speak. The problem is that the hyoid is perhaps unique in having no articulation with any other bone in the body, and therefore tends to get lost in fossils. Consequently Neanderthal hyoids are often missing and it took until 1989 for it to be established that they were like ours.

A couple of issues are going to come up in this post which are probably going to be considered idiosyncratic on my part. Here’s the first. Although I am aware that the FOXP2 gene is considered important in human capacity to use language, and Noam Chomsky believes in an innate capacity for language as a distinctive feature of the human species, I have issues with this as potentially speciesist and am disappointed that such a clearly politically radical figure as he would promote this view. I believe humans stumbled upon language before we had a special ability to use it. There are examples of other species being able to use spoken and signed language as language, as opposed to merely imitating it, notably Psittacus erithacus, the Afrik/can Grey Parrot, who presumably had no predisposition in their genes for using it beyond the ability to produce speech sounds and so forth. Clearly a certain kind of cognition is necessary for this to happen, along with the ability to produce the sounds physically, and once spoken language exists it’s going to be selected for compared to individuals who don’t speak, and this will lead to some kind of marker in the genes – perhaps we are better at producing or hearing a wider range of speech sounds than other species for example – but the initial moment when the first baby made a sound like “mama” whose parent then interpreted it as a reference to her, which was perhaps the beginning of language, did not in my opinion depend on very specific physical traits and could have occurred in another species.

The genomes of living humans include a few genes from the Neanderthals and it’s thought there was hybridisation tens of millennia ago in our history. To a very limited extent, we are therefore Neanderthals ourselves unless we’re Afrikan. The highest percentage of Neanderthal genes is found in East Asians and they’re usually absent from people all of whose heritage is from Afrika south of the Sahara. Neanderthals would probably have been fair-skinned and maybe also blue-eyed, and have had straight hair. I personally wonder if they had epicanthic folds, which of course have a higher incidence among East Asians but are also found in Caucasians without any Asian ancestry, and I’m guessing that those people might also have inherited that trait from Neanderthals. Recently the Neanderthal genome has been in the news for conferring greater resistance to SARS-CoV2.

Now for the reason I’m writing this today.

In recent years it has become possible to culture brain cells in Petri dishes. This isn’t the same as growing an entire human brain in a vat, but involves producing pinhead-sized agglomerations of cells. Recently, a gene linked to brain development in Neanderthals has been spliced into human cells and grown in such a dish. For many people this has a high yuck factor. The specific gene involved is NOVA1, on the long arm of chromosome 14, which is associated with various cancers but also nervous system development. There’s an indirect connection between familial dysautonomia and the NOVA1 gene which primarily involves the autonomic nervous system and insensitivity to pain and sweet tastes, among other things, but as far as I know doesn’t influence cognition, so that doesn’t necessarily give us a clue, although it’s possible I suppose that the inability to taste sweet might be related to Neanderthal diet in some way. That’s a bit of a reach. Whatever else is so, mini-brains with the archaic NOVA1 variant look rougher to the naked eye than the smoother versions which have the variant common in today’s population. The archaic version developed more quickly than the unaltered one and started to show electrical activity sooner. In write-ups of this experiment, we’re assured that these mini-brains are not conscious.

I have a major issue with that assertion.

The question of the existence of consciousness is sometimes referred to as the “hard problem”. It’s been suggested that it may even be so hard that it’s beyond the capacity of the human mind to account for it. At the same time, there’s a recent strand in philosophical thought, characterised by Daniel Dennett, which is sceptical about the very idea of consciousness as an irreducible property. I can’t take Dennett’s views here seriously, for the following reason. He has made a very good argument for the idea that dreams are not experiences but false memories present in the brain on awakening onto which the mind then projects the impression of previous events. I take this idea fairly seriously although I don’t do the same thing with it as he does. It’s one reason why I recount dreams in the present tense. However, a good counter-argument to this is that lucid dreams – dreams in which one knows one is dreaming and is able to control the dream world – aren’t experiences either. Although he does produce an argument for this, I believe that his reason for making this assertion is kind of ideological, because we practically know that lucid dreams are experiences. They might not be dreams in the same sense as non-lucid ones are, but they are experiences to my mind, and claiming they aren’t seems to be part of his attempt to shore up his view of the nature of consciousness.

Dennett is sceptical about qualia. These are things like the “sweetness” of sweetness, the “purpleness” of purple and so on. They’re what people are talking about when they say “my red could be your blue”. His doubt about their existence is based on the idea that they are not a definable concept. This to me is a silly denial of subjectivity which makes no sense in itself. Dennett’s motivation for believing that dreams are not experiences, qualia don’t exist and that even lucid dreams are not experiences is based on a more general view of psychology that consciousness is a specific faculty within the brain which may have evolved and has selective advantages. This thought leads one into seriously murky ethical waters because it seems to be a rationalisation of the idea that some other species of animal are not conscious, which is suspiciously convenient for non-vegans. It just so happens that the voiceless don’t suffer because they don’t have a voice. How very useful this is for someone who eats meat. Kind of as useful as believing Black people are not conscious would be for a racist.

My own view of consciousness, panpsychism, tends to be seen as equally silly by some people. It’s my belief that consciousness is an essential property of matter rather like magnetism is. A ferromagnet is a particular arrangement of charged particles whose domains within, say, a lump of iron, are aligned and it’s able to attract ferrous metals such as steel. There are other, similar magnets, such as rare earth magnets, which are magnetic in the same way but contain no iron at all. On a subatomic scale, magnetism is manifested by elementary particles with spin and axes which amount to tiny electrical circuits, and I have to admit that my understanding of actual, fundamental magnetism is not very good, but there are clearly non-magnetic substances too, such as granite and most blood (unless it’s infected with malaria). Even these non-magnetic substances, though, do consist of magnetic particles.

Consciousness is the same, to my mind. Everything material is conscious, but in order for that consciousness to become manifest, matter needs to be arranged in a particular way, such as a human nervous system. However, just as there are magnets which are not made of iron, so there could be sentient beings who are not made of the same stuff as we are. Objects which have nothing like sense organs or motor functions are in a sense severely disabled entities, but they’re still conscious. This is my panpsychism.

I should point out too that panpsychism is unsurprisingly quite controversial and often ridiculed in philosophical circles, although good reasons for doing so are sometimes lacking. Even so, there are other accounts of consciousness, one of which involves the idea that it’s generated by a network of “black boxes” interacting with each other, which in the case of the human brain amount to nerve cells. You don’t have to believe in panpsychism to assert that a tissue culture is conscious, and to me it’s entirely clear that the assertion that anything made of matter is not conscious is not based on any kind of evidence but a bias towards the kind of view of the mind-body problem asserted by Dennett and others.

Consequently, it definitely isn’t safe to say that these “Neanderthal” mini-brains are not conscious, or that the ones based on unaltered Homo sapiens cells are not conscious. Before I go on to talk about the internet as potentially sentient, I feel a strong urge to go off on a tangent about my experience of the Mandela Effect.

I have several more detailed posts on this issue on this blog, here, here and here for example, but in the meantime I will sum up what it is before going on. The Mandela Effect is the situation where a number of people agree on a memory which is markèdly different from the consensus or establishment version of that memory. Most of the time, this is about minor details such as spelling of brand names or the appearance of brand logos, but occasionally the discrepancy is more significant. It’s named after the impression many people had that Nelson Mandela had died in prison in the 1980s, and sometimes that this led to a revolution which overthrew apartheid in South Africa. History clearly appears to record a very different chain of events involving Nelson Mandela being released from prison in 1991 and becoming president of South Africa soon after. I think that’s it anyway. There are various unusual reasons why I take this seriously which are largely based on Humean scepticism about cause and effect and the existence of possible worlds, which means I tend to deprecate accounts which merely refer to confabulation as an explanation – the construction of false memories due to misconceptions. There is some evidence against this being true, such as the fact that when the position of landmasses on maps varies, it always does so along the direction of continental drift and never at an angle to it.

I have a few personal Mandela Effects (MEs) which are rare but shared with at least two other people, and they tend to have things in common with each other. One of these is that a science museum had a planetarium like robot which responded to heat, light and movement and was run by a minibrain grown from cultured mole nerve cells, in the mid-1970s. Two similar MEs of mine are that in the late ’70s a process was devised to measure intelligence via brain scans which was used in selective education by the DoE in England to replace the 11+, which was later exposed as unreliable and discontinued, though this was a scandal because it adversely affected the lives of many people who were children at the time. A third one was to do with some guy who designed and built a domestic robot which was able to read aloud by 1975. These are three of many, and they are conceptually connected by being about intelligent-seeming neural processes. If they happened, they would’ve required an understanding of neurology which was absent at that time, in the case of the domestic robot presumably via some kind of reverse engineering. I accept that hardly anyone else has these memories, but it’s still odd that two other people who had no strong connection with me at the time do have them. And the thing about these memories, particularly the museum robot, is that they could potentially be realised by this kind of culture of brain cells in a Petri dish.

Now for the idea that the internet is sentient.

It was once asserted that the last computer a single individual could fully understand was the BBC Model B, a microcomputer which came out in 1981. There are a couple of problems with this statement. One is, what is meant by “fully understand”? It’s certainly possible, for example, for someone to hold the network of logic gates which constitutes the BBC Micro’s 6502 microprocessor in their head at the same time as the structure on that level of the 6845 chip responsible for its graphics capabilities and the SN76489 chip responsible for its audio, and then extrapolate from that to the machine code of the system software in its interaction with the motherboard and memory mapping of these various bits of hardware, although it would take some doing for most people. However, if I did that I would have a vague understanding of how the NPN transistors work, involving electron holes and their relay-like behaviour, but to be honest my understanding of silicon doping, for example, is pretty limited. When one says that the BBC Micro can be completely understood by one person, is that supposed to include the aspects of materials science which make the production of its hardware possible, or the mechanical properties of the springs in its keyboard? What does it mean to “fully understand” something? The other problem with this assertion is that the BBC Micro, as I understand it, isn’t essentially more complex than the original IBM PC. The latter has more memory and a more complex and faster processor, and its system software is usually PC-DOS or CP/M-86 and more advanced than the BBC’s MOS 1.2 and Acorn DFS, but it can still be understood and it lacked the built-in graphics and sound hardware of the eight-bit computer which ended up on the desks of so many British secondary schools. Later on, with sound and graphic cards added, the latter including the very same 6845 as used in the BBC, it still wouldn’t’ve been as complex and would still have been comprehensible. It seems to me that the ability to comprehend these devices fully in that sense probably ended around the time Windows 3.0 was released in 1990. But whatever else is the case, the point at which any one person could be said to understand a device including both hardware and system software is now decades in the past.

Now take these two facts together. Firstly, we really don’t know what makes consciousness possible. Secondly, the internet, a network of billions of devices hardly any of which are understood to a significant extent by any one person, is extremely complex and processes information it gathers from its inputs. And yet it’s often asserted that the internet is not sentient, as if we know what causes sentience. At the same time, there are many internet mysteries such as Unfavorable Semicircle and Markovian Parallax Denigrate, which can often be tracked down to some set of human agents, but nobody has a sufficient overview to be confident that every single one of these mysteries has a direct human cause, or even that a fraction of them have.

Hence I would say that we might suppose that the internet is neither conscious nor sentient, but in fact we don’t really have sufficient evidence that it isn’t. It really has quite a lot in common with a brain, in any case we don’t know why anything is conscious, and it’s even possible that everything is. Therefore, just maybe, the internet is sentient and nobody can confidently say it isn’t.
