This post addresses several interesting visual and physical phenomena that implicate cognitive processes in communications not only between subconscious and conscious thinking (Earth and Humanity, respectively, in the DDJ), but also with the range of chemical and physical connections between thinking and our physical body (Heaven in the DDJ). This is very much a work in progress, so it may not be clear by the end of this chapter. The title refers to discordant processing because, as suggested by previous clinical results (meditation studies) and theoretical considerations, cognitive processes are not operating uniformly or properly, at least not in my brain. So, we’ll start there.
DISCREPANCIES IN LEFT/RIGHT VISUAL PROCESSING
I have identified discordant visual processing in several ways both during introspection sessions and with retinal input. It is not obvious if the two kinds of discrepancy are related by physiological inconsistencies with incidental impacts on vision and/or cognition, so it’s important to proceed cautiously.
Previous posts have alluded to the use of memory to assist in the construction of visual qualia and the creation of anomalous qualia, visual and otherwise. The reported asymmetry of anomalous visual qualia in the left and right visual fields suggests variable access to memory in their creation without retinal input. For example, faces often appear as profiles, or nearly profiles, usually as if viewed from the right; when faces are seen head-on, the right side (looking at them) is blurry and deformed whereas the left half is often very clear and well proportioned. This difference suggests that the right visual cortex (left visual field) has better access to memory; in other words, my left and right visual cortices are not synchronized, at least not when in default mode (eyes closed).
Another interesting visual phenomena is the illusion of opening and closing my eyes when both eyelids are already closed. This illusion appears to favor the left visual field; i.e., it “feels” as if the left eye is open whereas the right eye often “feels” as if it is closed. When an eye is “opened” in this manner, the visual field becomes brighter. I can manipulate the illusion; “forcing” the right eye open and the left eye closed. This effect may have nothing to do with visual processing, instead being dependent on nerve and muscle connections in the eyes themselves.
The consequences of a discrepancy in visual processing are unknown, but could consist of several effects:
- poor visual processing, even with retinal input;
- practical problems with recognizing objects because of poor image completion processing; i.e., searches require longer and depend on more accurate retinal input
- unknown collateral issues, based on treating visual processing as representative of other cognitive processing
The human body is theoretically symmetrical. Mine is definitely not, from my longer right arm, twisted right hip, congenitally weak right knee, to the semi-paralysis of the right side of my face (i.e., muscles don’t respond well, making smiling difficult and lopsided), and sagging right eyebrow. All of these differences have existed all my life. It makes perfect sense then that the brain would be asymmetrical as well. When reading about this phenomenon, I came across an interesting research result:
The results suggest that while either hemisphere can generate spontaneous facial expressions only the left hemisphere is efficient at generating voluntary expressions.
In other words, our brains are apparently not perfectly symmetric in operation.
I’m going out on a limb here (again). My difficulty in generating voluntary expressions could be due to a left-hemisphere anomaly, if this is a valid result. Furthermore, speculating even more, the weak left visual cortex functioning described above could be caused by an anomaly in my left hemisphere. This is of interest because of potential collateral effects and the use of proxies to study cognitive function, as has been discussed throughout this blog.
Correlation does not directly indicate causation, but it is consistent with a common cause, even if two processes are not directly related through a physical mechanism.
RELATIONSHIP TO THE DAO DE JING
What does this mean, with respect to the stated purpose of this inquiry? From DDJ 2,
“All the world knows beauty as being beautiful, thus not being beautiful exists. All know good as being good, so not being good exists. Being and Non-being arise together. Hard and easy complete each other. Long and short shape each other. High and low fulfill each other. Voice and instrument harmonize. Before and after form a sequence. This is why people of Wisdom dwell on matters on non-designing action and go about teaching without words.
The myriad beings are active but do not undertake [to act], produce but do not take possession, function but do not depend [on design and control]. Gains are accomplished but not laid claim to. Because there is no laying claim, [gains] are not lost.”
If a well-functioning cognitive system exists, a bad one exists too, but it’s not the end of the world. We don’t have to say, “That’s just how I am…accept me for what I am.”
Learning our strong and weak points, both physical and mental, allows us to harmonize them and become more united in our approach to life. This is especially relevant to mental processes, which determine our emotional state and thus satisfaction.
I’ve spent quite a bit of time examining how our subconscious and conscious minds (Systems 1 and 2) interact. That’s because of the difficulty of exploring their relationship. I used visual perceptions for this effort and the work continues. It is very slow going; it isn’t easy to develop connections between parts of our brains, but progress thus far suggests that it is possible.
UPDATED RESULTS ON VISUAL QUALIA
First, I’ll give a brief summary of progress in controlling and creating visual qualia. I reported on multi-object visual qualia in Chapter 9, six weeks ago. As of this date, I can report slow progress in controlling and initiating visual qualia. I have learned that there are two preliminary steps: 1) clear my mind of all qualia (thoughts, visual, ear worms, etc.); 2) create a symbolic representation of the object I’m trying to visualize. This is a lot easier than going straight to a pictorial representation.
I sometimes create the blue sphere object, but not often. Usually, it appears as a globe (with the wrong continents) and is usually spinning. I can stop the spin sometimes but can’t hold it in my visual field for long. As far as picturing my face, no luck with a pictorial representation but I’m getting better at symbolic representations. This seems very strange to me. I don’t know what it means not to be able to picture yourself.
PHYSICAL NATURE THEORY
So far, this blog has discussed integrating the conscious (humanity from DDJ) and subconscious (earth) minds through the creation of intentional pictorial representations (visual qualia). Keeping in mind that I’m applying the concepts presented in the Dao De Jing to the three-part entity we call ourselves, we can look at what the DDJ says about the body (Heaven). It isn’t much.
From DDJ 10: In nourishing your physical nature and caring for the One can you integrate [them]? …
This is the starting point, integrating the physical aspects of our person with the ambiguous One. The One indicates Being, existing as opposed no Nonbeing, whatever comes before birth and our lives. In other words, we must take care of our body as well as the mind. The relationship between the body and mind has been discussed by many authors and is a basic tenet of most spiritual systems. That’s not what the DDJ is talking about. The DDJ is referring to something more fundamental.
DDJ 11 presents an interesting metaphor:
Thirty spokes together on one hub, but it is vacancy [in the middle] that makes the cart useful. Firing clay makes a vessel, but hollowness is needed to make it useful. Cut doors and windows in walls to make a room, the empty spaces are needed to make it usable. Therefore, Being serves the purpose of benefits, Non-being serves [as a resource] for use.
Equating Being with the One (from DDJ 10) implies that integrating the body with Being requires nurturing the body in an iterative process.
Recalling that Being creates Yang and Yin (what I’m treating as emergent pseudo-forces); these unknown forces create our bodies and thus minds as we physically develop. Science can’t answer the question of when we become alive, or what causes the metamorphosis from a collection of embryonic cells into an organism. Thus, unlike studying visual qualia in previous chapters, we can’t identify a proxy for this process; however, we can attribute this process to whatever force causes our cells to continuously regenerate. In other words, Yang and Yin are the unidentified mechanism for cell growth and regeneration.
Returning to DDJ 10, the integration of our physical nature with Being is a life-long process that keeps us alive. The ancient sages who compiled the DDJ understood this while not knowing how it works any better than modern science. It is mostly an autonomous process but, like controlling visual qualia, we can influence it through our behavior.
One last word about DDJ 11: These metaphors reveal the importance of the impenetrable Being. It is more fundamental even than Yang and Yin, which can be treated as biochemical processes. Some have called this the “spark of life.” Some call it the “soul.” I’ll just stick to Being. No matter what we call it, this foundation of existence is as empty as a wheel hub, a clay jar, or a room. It is an abstract concept that is critical to making use of physical objects. Thus it serves as a “resource” for our use, even if we can’t identify it.
There are a number of ways to promote the regenerative processes that integrate our physical nature with our Being, our essence. The DDJ doesn’t say much about this, but here’s a starting point:
From DDJ 12: …The five flavors ruin a person’s palate…This is why the [ancient] sages were for the belly, not the eye. They let go of the one and took hold of the other.
The five accepted flavors are sweet, sour, salty, bitter, and savory. These are what we can taste. Obviously, we enjoy tasting food, so we pile these on our bland cereals and vegetables. We should be eating for sustenance, not taste. As we eat more sugar, fat, salt, and spices, we lose our sense of taste for food itself. This is an endless cycle if we don’t curtail it. Stop chasing the short-term pleasure of strong flavors. This is reinforced in DDJ 53:
…taste what is without flavor…
Learn to enjoy food for what it is, rather than what has been added.
We can add a complementary act to this: stop eating so much. Food including fat, spices, etc tastes good, so we eat more of it than we need. This problem is compounded by the fact that it takes about 20 minutes before we become aware of our stomach being full.
Overall good health allows the body to function better. It’s that simple. Good health requires moderate exercise, enough sleep, lowered stress, etc. All the things nutritionists encourage us to do.
One final (I’m sure there are plenty more) thing we can do is spend some time during meditation focusing on our body. This is recommended by most meditational techniques. It works.
ACTION AND RESULTS
Turning again to my test subject (me); since I started this blog, I have stopped using any seasoning on my food, even salt. I have also reduced the quantity I eat, measuring the total food with a scale, not individual food groups (e.g., meat, cereal, vegetables). Consequently, I have lost 35 lb. and 3 inches off my waist. I enjoy what used to be bland food: e.g., spinach, rice, beans. I don’t go hungry either. My stomach has become accustomed to not being full after every meal. I still eat meat, mostly salmon and chicken, with a little beef once in a while.
I’ve started doing light weight training and stretching exercises, as well as increased my walking to 1.3 miles every day, which takes about 35 minutes. I walk four times a day because I have to take it easy with the walking due to lifelong issues with my knees; however, the lower weight has decreased the occurrence of discomfort.
I’ve decreased my drinking substantially. Now, I average 8 cans of light beer (~100 cal, 4.2% alcohol) per day, and consume no wine or distilled liquor. I don’t inhale when I smoke, but still…
I’ve got a long way to go, just as in controlling anomalous qualia.

The discussion thus far has focused on visual qualia because they are easy to recognize. I have presented examples of random objects and, after some practice at introspection, demonstrated that some control is possible. I don’t imagine that one can go from experiencing a few random visual qualia to creating scenes of tropical beaches in a few introspection sessions, however; instead it will probably take years of reconfiguring the virtual network that connects my visual cortex to my conscious mind. Therefore, this is the end of the discussion of visual qualia for now. I will report on notable improvements in consciously creating and controlling them as my skill improves.
This is only the beginning of understanding and controlling other qualia, however. I will briefly introduce several kinds of random qualia I have experienced and suggest ways to apply the TOSCA model to them as well.
First we can go through the other senses:
Many of us suffer from a periodic phenomenon known as “ear worms,” also known as Involuntary Musical Imagery. I propose that these are qualia produced by the same process as visual qualia; i.e., the auditory cortex is randomly generating packets of sounds (usually music) that sometimes reach the conscious mind coherently and are transformed into auditory qualia. We don’t have to be thinking about the song, although some research suggests that they can be triggered by memories related to the song (e.g., emotional response or an activity associated with it) as well as repeated exposure in the past. Most methods for dealing with them are anecdotal, like humming a different song or focusing on a cognitively challenging task.
Since I don’t hear Earworms constantly, it’s difficult to apply the introspection method regularly. However, they have sometimes occurred while I was focusing on visual qualia. One approach would involve focusing on the music and trying to expand the auditory qualia into a full song, remembering the lyrics. This might work to develop a mechanism like controlling the random visual qualia.
Not having a lot (none that I can remember) of random tactile sensations, I think this should include pain. I’m referring to what was called “growing pains” when I was a child. The cause is unknown. They are probably just like the random pains adults get, but for older people random pain is accepted as “getting older.” This category should include any pain with no observable cause, like most headaches, backaches, etc. I don’t get headaches very often, but meditation (i.e. introspection) has been shown to be a useful treatment for migraines. I imagine it should be similarly useful for random aches. Later posts will address the issue of improving unconscious communication between the physical body and our mind (conscious and unconscious).
SMELL and TASTE are inconsequential for me and won’t be discussed.
Emotional qualia are the sudden onset of emotional feelings, like disgust, anger, sadness, etc. These are complicated because there is a strong hormonal basis for true emotions. For my purposes, I am neglecting emotions that are reasonable responses to external stimuli such as danger, or learning about a tragedy occurring to someone we know. We are interested in transient emotions like a flash of anger, a sudden surge of excitement or happiness for no apparent reason. Maybe an image could initiate such an emotional qualia because there is no real stimulus in the environment, only an image or another quale – a thought quale. We’ll discuss those next.
Such emotional qualia can become a problem for some people, and many methods have been developed to address them, such as cognitive behavioral therapy, meditation, etc. Our interest here isn’t to to treat them as a problem whose symptoms need to be controlled but instead as a form of subconscious communications that we want to understand and control.
During introspection sessions, I am often distracted by auditory and thought qualia, but not usually by emotional perceptions; however, they may be disguised by more powerful qualia and go unnoticed. I will focus on them in future sessions. They probably would be discernible if an introspection session were to be completed during a time of emotional stress. More on that later.
We all have random thoughts. Sometimes they are about a subject we’ve been working on and are intuition, which is critical to creativity. Other times we have random thoughts, which have no bearing on anything. This second kind of thought quale contributes to our short attention span, but we have to be careful how we define this. Selective sustained attention, when we intentionally focus on something, is on the order of 20 minutes, whereas transient attention is a short-term response to a stimulus that temporarily attracts/distracts attention. This study is interested in the latter. Although there is no agreement by researchers in the field, we can all collect our own subjective data on the subject.
Some writers have reported a number on the order of 10 seconds for focusing without intent, like a quick thought that isn’t acted on, and is then forgotten. Certainly, our eyes move around very rapidly. In fact, the transient component (not under conscious control) of our visual attention span doesn’t appear to be much more than 100 milliseconds. This is consistent with the alpha wave brain frequency discussed in Chapter 3 for passive attention (8 – 12 Hz). In other words, if we aren’t intentionally focusing, our visual attention and probably cognitive attention span is short; one possible reason for this proposed by Nakayama is that sudden stimuli shouldn’t distract a person from something important that they’re focused on.
With respect to my own observations, this is a rather short interval for cognitive qualia to persist, but it is consistent with how easily my attention drifts during introspection sessions. During these sessions, I’m not focusing my thoughts on anything but simply trying to retain or control a visual qualia. Not much thinking is involved in that procedure. In fact, I try to keep my mind clear. That’s where cognitive qualia come in as distractions, which interrupt whatever attention I’m trying to focus on visual qualia.

Chapter 8 introduced intentional visual qualia. This post is going to back up a little and discuss visual qualia that are random, but not quite anomalous, or at least not unrecognizable partial objects. Before discussing the results of introspective sessions investigating multi-object visual qualia, I want to take a moment to discuss what an object, and thus a visual quale, is. The objects reported in Chapter 5 were treated as independent qualia. These qualia interacted (colliding, morphing, etc), creating new qualia, which continued the cycle. This brings up an interesting question: Are complex mental images composed of a single quale, or do qualia combine into a new quale having characteristics of its components? This has implications for how different functional parts of the brain (e.g., visual cortex) store representations in working memory to maintain and modify input to the conscious mind.
This might sound like a pedantic question, but the answer could influence how manipulating qualia can improve cortical function, for example functional communication and working memory.
Imagine yourself (create a symbolic representation) on a tropical beach at sunset, walking along the sand, the waves gently breaking on the shore. For our purposes, this is a multi-object, multi-qualia perception (e.g., visual, tactile, auditory, emotional). It is a single scene with multiple components. Most people can imagine it using symbolic representations of all of the qualia it contains, even if we can’t see the sunset, hear the waves, feel the sand, smell the ocean, or feel the sense of peace this image is supposed to convey.
This is a difficult scene to unravel because it’s easy to imagine turning one’s head and seeing the palm trees along the beach, and then looking offshore and seeing the sun on the horizon. Perhaps turning around and seeing the trail leading to the cabana. There are many components to the qualia we perceive. Are they separate qualia, or has the conscious mind created a new quale from the myriad of imagined perceptions coming from the subconscious? Recall from Chapter 3 that our brain works at pretty high frequency, so qualia can be updated (and replaced) relatively quickly. For example, while imagining this tranquil scene, its component qualia are updating at 8-12 Hz (8-12 times per second), and possibly as high as 35 Hz.
We will keep this in mind in future posts that discuss multi-quale scenes like this one. For consistency, I will retain (for now) the original definition of a quale as representing one object. Multi-object perceptions like the tropical beach will be defined as SCENES.
In other words, a scene is composed of qualia that are constructed by the conscious mind from packets, themselves composed of bytes of binary neuronal signals arriving from parts of the brain processing different kinds of stimuli (e.g., sight, sound, touch, smell). There’s a lot that can go wrong in this sequence. No wonder many of us can’t smell the rotting seaweed!
This post discusses two kinds of SCENES: (1) static mental images with multiple objects that persist long enough to be examined closely; and (2) dynamic sequences of multi-object images that change reasonably slowly over a sufficiently long time interval to be remembered. The cases discussed below were randomly generated and I exercised no control over them. I was a neutral observer.
One example of a static scene I recall occurred after I had controlled the anomalous visual stimuli. Two or three people (one woman) were dressed formally in a room with pictures on the wall and a table. They were close together. It lasted about five seconds. It was realistic but I didn’t recognize any of the people. The stock image could have come from thousands of movies and photos I’ve seen. I don’t know if it was modified or unaltered. Static scenes don’t seem to be as memorable as dynamic ones, which will be discussed next. It’s hard to forget those.
The first example we will discuss occurred several times on different days. It includes several large fish in a shallow river or lake; rocks; a sandy bottom covered with ripples and aquatic plants; the surface of the water is seen at the top of the scene. The water has an overall greenish hue, giving the fish a similar color, although they are very realistic, with irregular coloring. The fish are swimming slowly past my viewing point. It lasted at least 30 seconds on each occasion.
This scene is based on the Amazon rainforest exhibit at the Aquarium of the Americas in New Orleans. I have been there many times. The view point is based on an open aquarium tank, seen through the glass wall facing the aquarium visitor. What is different is that there is more depth to the mental image. The channel in the real tank is only a few feet across, although it is more than 50 feet long. The mental image fades in the distance, more like a natural water body rather than an aquarium tank. In other words, it isn’t a static photo of a scene I have certainly seen enough times to remember; instead, my subconscious has manipulated it, adding more depth, other objects (e.g., aquatic plants), and turned it into a movie. This sequence of images was delivered to my conscious mind in carefully coordinated packets and assembled as a quale. I call it a quale (more correctly a series of related quakes compiled into a scene). Why? I don’t know the answer, but we’ll talk about that in a later post.
The second example of a dynamic scene is striking and requires expansion of the idea of subconscious manipulation of memory to create visual stimuli.
I’m looking down on a wide, grassy valley with low hills in the distance. There are a few knolls within the valley floor. I’m not very high, maybe on a knoll, and about 200-300 yards distant. I have to turn my “head” (mentally; no head motion required) to view the expanse of the scene. The valley is empty. Then, a large group of men enter from the right side, dressed in blue with a couple of them riding horses. I have the impression that they are soldiers (maybe Union troops from the American Civil War) because several are carrying large flags. I have an emotional response to the soldiers; I feel that something is about to happen, maybe a battle. They march along the valley in front of me.
I look to the left and see what appears to be hundreds, if not thousands, of animals (I had the impression they were wolves) entering the valley. The soldiers can’t see them because of a slight rise between the two groups. As the soldiers start up the rise, I move in for a better look. This is interesting because I intentionally moved my position, hovering I suppose. I remained elevated. I get to within maybe a hundred yards when the protagonists see each other.
The scene jumped a little here, like fast forward, but smoothly without interruption. Suddenly the soldiers were running back the way they came with the wolves in pursuit. When the wolves are within about a hundred yards of the retreating men, they begin to dissipate into dust. We’ve all seen this special effects technique in science fiction movies. The dust cloud caught up to the men as the last wolf dissolved into dust. The troops were enveloped in the dust cloud. End of scene. It lasted almost a minute without interruptions and I was fully engaged as an observer. I had no idea what was going to happen and was quite surprised at the ending.
This scene is fascinating for several reasons: (1) I never saw this before; (2) I felt a slight sense of anticipation (I was emotionally engaged); (3) I controlled my viewpoint, interacting as it were, with the scene. Let’s address each point in turn.
(1) I have certainly seen formations of soldiers, in movies, paintings, dioramas, you name it. No surprise there. I have also seen plenty of valleys (this looked like a landscape from the Valley and Ridge region of central Pennsylvania). As I said, I have seen the special effect of dissolving objects into dust many times. I’ve also seen wolves and images/videos of groups of animals moving (e.g., buffalo in the U.S., migrating herds in Africa). In other words, all of the components of the scene came from memory. The interesting issue is how they were combined into a completely new scene that lasted almost a minute, all with no conscious control on my part.
(2) I’m not sure if my emotional response was part of the scene or my reaction to what I was viewing. It didn’t evolve into fear for the soldiers, however; when they were fleeing, I was indifferent. It was only when the soldiers first appeared that I was apprehensive.
(3) I controlled my view point by turning my head (essentially extending the scene through conscious action), and moving to a different location for a closer look, before returning to my original viewing point. This implies that the scene was responding to my conscious act (thought actually), my desire to change the view. That is dynamic interaction. This means that, not only were new details created on demand, the objects were stored in working memory and used to recreate previous view points. This has important implications for learning to control how our conscious and subconscious minds interact.
Chapter 7 described preliminary efforts to consciously influence visual qualia. I was able to stop the rapid motion of many mental objects and improve the completeness of some. Fewer objects filled the field of vision and individual objects could be isolated and their orientation changed. That’s the best I could do after about a month of 30-45 minute daily sessions. What these efforts have in common is that they attempted to influence the behavior of anomalous visual qualia. Parallel with these experiments, I have also been trying to create new ones.
To recap Chapter 3, millions of individual neurons firing in a (usually) ordered pattern send a large number of packets of data along virtual networks of neurons to arrive somewhere in the cortex, where they are assembled into perceptions, which we are calling qualia. The anomalous mental images discussed in Chapter 7 resulted from packets arriving from the visual cortex without input from the retinas. Their original purpose is (probably) to speed up visual perception, but when no retinal input arrives to the visual cortex, they are noise on the network and thus appear random. However, this isn’t the complete story. In fact, most studies (and there are few) of mental images focus on people who intentionally create visual qualia. This implies that there is a feedback loop between the conscious mind and the visual cortex, possibly with additional input from other parts of the brain (e.g., memory, emotions).
Scientists who study vision have identified two ways of creating mental objects without retinal input: 1) symbolic visual representation; and 2) pictorial representation. People who are unable to create type-2 images suffer no decrease in their ability to manipulate complex 3D objects mentally. How is this done?
No one knows what’s going on in our conscious mind when it creates visual qualia, so I’m necessarily speculating. Symbolic representations can be thought of as a list of features, like a table of points describing lines, points, etc. and how they are connected. It would include details about color and other properties. Every detail of an object can be described in the list and combined on-the-fly during mental manipulation because of the brain’s parallel processing capacity. The amount of detail depends on how well the object is remembered or imagined.
A pictorial representation is no less dependent on memory. It can even be false if it includes different memories superimposed on one another. It’s important to understand the difference because the symbolic representation is obviously the more basic (default) of the two kinds of qualia. Thus, it’s a good foundation on which to create intentional visual qualia. I propose that we have to create a symbolic mental image before a pictorial one can be created. Think of it like a framework, even though it can be just as complete in detail.
The first experiment was to create a blue ball. Easy to create symbolically. Not so much pictorially. I got a green pear-shaped object that wobbled as if filled with water. It lasted about ten seconds, during which it morphed and finally became a distorted green ball, before disappearing. After a few sessions, I could picture a blue ball about half the time. Other objects were interfering. Then I tried a baseball, focusing on the unique seam pattern. I got close but it wasn’t white. A soccer ball, with all those black and white pentagons, came out irregularly polka-dotted and not black and white. All dark colors. The biggest problem is STABILITY; the objects morph before I can mentally change them to proper appearance.
As discussed in Chapter 5, many of the anomalous visual qualia I experience are faces. Most are deformed or very dark with little color. But occasionally a complete face would appear, either in profile or facing me. I focused on making the faces more realistic. There was a noticeable improvement after a few weeks. Sometimes even complete people moving as if in a video, often talking but I didn’t hear any words. It’s still not under control, however; distorted shapes are the dominant visual qualia. None of the people I see are recognizable, not even as well-known actors. They may be amalgams of many faces or made up. I don’t know.
Since I was able to control faces to some extent, I decided to focus on my own face. That should be well-known to me, but nothing appeared. I couldn’t even generate a symbolic representation. I tried with people I know well, but no luck there either. Sometimes a recognizable photo would appear. A memory. I’m looking for an image of my current appearance, so I started studying my face in the mirror several times a day. I couldn’t create a mental image of my face. That struck me as strange, so I sketched myself in front of a mirror and focused on details that may have been overlooked in a casual examination, like while shaving. (The sketch doesn’t look like me.)
After working on this exercise for a few weeks, the best I can do is a brief symbolic visual quale. In other words, I am aware of an image but can’t see it. I’m currently focusing on my eyes, nose, mouth, separately and having limited success. Meanwhile normal faces are occurring more often.
The next chapter will discuss more complex visual qualia.
As I’ve said before, The Dao De Jing is open to interpretation, and has been throughout its written history (at least from the 4th century BCE). Following this long tradition, I’m going to break with P.J. Laska in interpreting DDJ 2, second stanza:
“The myriad beings are active but do not undertake [to act], produce but do not take possession, function but do not depend [on design and control]. Gains are accomplished but not laid claim too. Because there is no laying claim, [gains] are not lost.”
Laska interprets the myriad beings in this stanza as being enlightened individuals (i.e., the Wise, from Goddard’s 1919 translation), which is in contradiction to his interpretation elsewhere, where they are all of the matter and people in the universe. I don’t like inconsistencies. Fortunately, applying the DDJ at the level of mental-physical integration doesn’t require a contradiction, at least not as applied in the TOSCA model.
The definition of the myriad beings/things as qualia is well described by this passage. It is entirely possible that the authors of the DDJ imagined qualia when writing this verse, in addition to applying it to the larger scales (e.g., personal, village). Visual qualia are temporary perceptions that are active and produce perceptions, and thus function to support consciousness. They clearly are not dependent on design and control, although that is a goal of the model. They are ephemeral phenomena that appear and disappear without conscious control.
How do we influence something as ghostlike as visual qualia? In Chapter 5, I defined five parameters to describe visual qualia: 1) KIND (e.g., geometric shapes, people, things); 2) ORIGIN (e.g., location in the visual field, the way they appear, intentionality); 3) DURATION (estimated in seconds); 4) COMPLETENESS (e.g., entire objects, pieces of objects); 5) STABILITY (e.g., the degree to which they change in appearance).
Just as with identifying visual qualia, influencing them is necessarily subjective. For example, someone with excellent mental image creation skills, influencing qualia may be innate whereas for someone who has never perceived even one, it could be extremely difficult. Since my experience falls somewhere between these two extremes, I will give examples from my experiments.
Rather than systematically attempting to influence each parameter separately, my initial work is trying to have some influence. After all, I don’t consciously create them and can’t turn them on and off at will.
First, we need to standardize the experimental conditions. After some preliminary tests, I’ve chosen to complete the tests laying on my back on a bed with a pillow, arms away from my body to avoid contact between my hands and body. The eyes are lightly closed. By the way, this won’t work if you’re are the least bit sleepy. The point is to remain completely awake and alert at all times.
The next step is far more difficult than lying still. Clearing all thoughts from the mind is critical. However, a little drifting doesn’t ruin the experiment but only causes the qualia to sometimes stop being perceived or, at worst, some progress may be lost and have to be repeated. This is extremely hard for me to maintain because the mental images remind me of memories or events, plans, etc, and I drift into thinking about these unrelated, undifferentiated qualia. Remember, the conscious mind is bombarded by data packets (e.g., thoughts, touch, hearing) and creating qualia from them. We’re focusing on visual qualia for now.
The third step is easier than it sounds. Keeping spurious thoughts out of mind, I speak (mentally) about what I’d like to control: for example, I might say, “Slow down,” or “I’d like to see faces only.” Don’t get anxious during these attempts. The qualia aren’t a video game and they don’t do your bidding.
The fourth step turns out to be rather easy once you see some progress. Be patient. I have discovered that several test sessions lasted 45 minutes with no sense of time passing. (No, I didn’t fall asleep.) When busy, your mind loses track of time. I usually end a session when I’m not seeing any more progress. Staring at blackness, or wildly cavorting images for that matter, can be very frustrating.
When I first tried introspection, it took as long as ten minutes for visual qualia to appear. Sometimes, it still takes that long but, more often than not, they begin within minutes or seconds. (We’ll talk about intentional visual qualia in the next chapter.)
I have been conducting experiments of 30-45 minutes duration every day for about a month (no daily log available).
At first, I used simple mental commands like, “Slow down,” to stop the dizzying dance of qualia I first reported. Such motion is rare now with no conscious effort. Sometimes, I can get a specific image to sit still, (e.g., saying “Stop moving.”) but I can’t keep it from morphing into something else. I think that image STABILITY is improving, but image DURATION is still very short. I can’t say much about COMPLETENESS because there were always “complete” heads at times although they were rare.
The parameter ORIGIN needs to be redefined to include position and orientation. I have discovered that I can move images sometimes within the visual field, as well as rotate them about 90 degrees. Not consistently, however. Also, the KIND of images seems to be changing. Whereas I initially perceived a crazy jumble of twirling and spinning objects, there are now fewer images in the visual field at once (sometimes only one) and they aren’t so unstable.
The next chapter will discuss specific experiments in creating visual qualia of just two kinds: balls and faces.

This chapter discusses the anomalous visual qualia reported in Chapter 5. First, we will refer to the Dao De Jing for guidance to interpret them in terms of the TOSCA model. Finally, we will examine their interpretation with respect to pursuing a path to enlightenment . Quoting from DDJ 42:
“The Way generates the One. The One generates Two. Two generates Three. Three generates the myriad beings. The myriad beings carry yin and embrace yang, fusing vital breaths to create [sustainable] harmony.”
This verse was discussed in Chapter 1. It’s time to refine that first-cut. The myriad beings/things have already been refined from “expressions of our tripartite body-mind system. These include actions, thoughts, and physical conditions (like being tired, hungry, etc.); anything that originates from our physical and mental state.” We now define them as qualia, generated in the conscious mind, in response to the arrival of packets of visual (for now) stimuli generated by the ordered firing of connected neurons (bits and bytes). This focuses on electrical signals and ignores chemical signals. We’ve thus restricted the TOSCA model to electrical communications (i.e., neural pathways or virtual networks carrying packets). This doesn’t restrict its application however since the central nervous system (composed of neurons connected to the brain) runs throughout the body.
Yin and yang were introduced as pseudo forces in Chapter 1 with the implication that they were invented by the authors of the Dao De Jing as an explanatory mechanism for a binary process (on or off). It is reasonable therefore to refine the definition a bit: Yang and yin represent the binary states of the individual neurons that contribute to packets merged into qualia.
Fusing vital breaths from yang and yin carried by qualia (myriad beings above) suggests that the definition used in Chapter 1 is no longer sufficient. The refined definition of vital breaths from DDJ 42 is that they are the packets arriving from the distributed network of neurons supplying the components of the final perception. This puts us on the path to how to interpret the anomalous qualia presented in Chapter 5.
Let’s differentiate an abstract object from a process. From DDJ 25:
“Something formed in chaos existed before the birth of Heaven and Earth. Vast and still, solitary and unchanging, it moves in a cycle…We do not know its name. If a word is needed we call it Dao…The Way [Dao] is a law unto itself.”
This is a reference to the universal unknown, but hints at the application of principles that can be inferred from the Way to earthly matters. There are many references in the Dao De Jing to the Great Way. This one from DDJ 18 gives a hint (that’s all you ever get from the DDJ) as to what is lost when the Way is abandoned:
“When the Great Way was abandoned, the ideas of moral perfection and correctness appeared.”
In other words, morality and correctness are artificial concepts introduced when the Way is not applied to the activities of humanity. Someone following the Way doesn’t need socially constructed ideals of behavior. This duality of the Way is probably the source of Taoism (Dao is also translated as Tao; I’m not an ancient Chinese scholar), a non-ritualistic religion that espouses joining with the natural flow of the universe. That’s not where we’re going in this study. This holistic interpretation is too metaphysical, although the result is the same. The TOSCA model doesn’t assume any metaphysical phenomena, but instead interprets the Dao (Great Way) as an abstract plan for mental-physical development. In other words, no belief system is required or encouraged.
The Way influences qualia in an indirect way, as alluded to in DDJ 34:
“The Great Way floods forth. It can flow left or right. The myriad beings rely on it to live and it does not refuse them. It accomplishes works of merit, but does not take possession of them. It clothes and feeds the myriad beings, but does not act as their master.”
And from DDJ 51:
“The Way gives life to the myriad things. Its endowment rears them, matter forms them, circumstances complete them…its endowment fosters, increases, nurtures, shelters, nourishes, supports and covers them.”
In other words, the Way guides the creation of qualia in consciousness, but cannot be expected to magically control how we think. It is only a plan of action. Our perceptions, thoughts, and emotions are created in our conscious minds from the huge number of neurons firing systematically. Often, however, neurons misfire or fire in a pattern following a less-than-optimal sequence of events (e.g., make a bad decision or don’t see everything in our field of view).
Finally, we can return to the anomalous visual qualia in the title of this chapter. The wild display of partial images I reported in the previous chapter are not the result of the orderly arrival of packets to my consciousness. My inability to control them, much less create them intentionally or stop them, is strong evidence that they are created by randomly arriving packets from the visual cortex. In a perfectly functioning tripartite mind-body system, visual qualia without retinal input (i.e., eyes closed) would only be created on demand, as when remembering or imagining, and they would be complete if not highly detailed. Something is malfunctioning.
The Dao De Jing refers to losing the Way and what happens; “moral perfection and correctness appeared.” In other words, we create rules to replace the smooth operation of our minds. The rules our subconscious/conscious mind creates aren’t necessarily accurate, just as social mores can vary widely among nations and through time. To recover the Great Way (the Dao), we must influence (but not master) the communication pathway from the conscious to the unconscious mind. The feedback loop identified in the visual cortex.
Notes: The Original Wisdom of the Dao De Jing, Translated by P.J. Laska, ECCS Books, Green Valley Arizona, 2012.
In the previous chapter, I referred to the inability of some people (including me) to intentionally create visual qualia. It might be asked why this matters? The short answer is, it doesn’t; but this blog isn’t about short answers. The purpose is to interpret the Dao De Jing in a meaningful way, as more than paradoxical proverbs. Unifying the three-part body-mind system requires a method to improve communications between these components.
The motivation can be found in the name of the model: Tripartite Organismic Stimulus-response Cortical Augmentation. The packets of processed sensory data that I’ve been discussing are the primary stimuli for the conscious mind. Its response consists of qualia, like mental images. The TOSCA model is a tool to help us visualize the communication pathways that make up virtual networks. Thus, by focusing our attention on the qualia, we can apply standard learning techniques like repetition and elaborative learning to improve (augment) these virtual networks. Better communication may even improve functioning of brain regions responsible for different mental processes (e.g., memory, attention). That’s the long answer.
Before going any further, let’s review how visual images are processed in order to understand how visual qualia are generated. Recent research on how images are processed in the brain is summarized in an article in Science Direct.
Each brain hemisphere has a complete visual cortex that processes one-half of the visual field (from both eyes). The right hemisphere processes the left half of the visual field and the left hemisphere visual cortex processes the right half of the visual field. These two half-fields are compiled into a single full-field image somewhere in the cortex. I couldn’t find an answer to that question, so I will assume that this process is part of being conscious, i.e., qualia are created after visual processing is completed.
I have referred to symbolic versus pictorial mental images. A pictorial representation is like a bitmap, a one-to-one mapping of the visual field to neurons in early processing of visual input. This has been demonstrated in mammals and even people. Higher levels of visual processing add symbolic information (e.g., color, motion) before the output is sent to the prefrontal cortex. Everyone sees pictorial images when their eyes are open, but how this is done isn’t known (or else is being kept a secret because I couldn’t find anything about it). Let’s rack it up to being “conscious” again.
The visual pathway also includes feedback between higher and lower level functions (e.g., from an identified and classified image with attached memories etc. to the generation of a raw image of the retinal input). Several studies suggest that mental images are part of speeding up perception. They are created, or retrieved from memory (the mix isn’t known), by higher visual functions and passed to lower ones as a first-guess at what’s being perceived. Such mental images may well be created constantly and simply not used at times; for example, when the eyes are closed.
This brings up an interesting question: are mental images memories, or something new, created on demand? If they are memories, they should appear as something recognizable, even if distorted. On the other hand, if the mental images we perceive (eyes closed) are new, we would expect to experience something that is clearly not a memory. I’m not sure the distinction is important, however, because even a newly created quale would necessarily be influenced by our experience and thus memories. Either way, communications from the conscious mind to the subconscious mind is occurring when visual qualia are intentionally created.
I probably should have added a separate post for what I’ve said above. Nevertheless, we have the background to understand (at least qualitatively) how visual stimuli can be far removed from anything we see in the physical world, and how the qualia are created by our conscious mind.
In order to identify any changes in the response (visual qualia) to stimuli from the visual cortex (the packets transported on the virtual network), we need a baseline. I will use occurrences of visual qualia from my experience during intervals of mindfulness meditation (i.e., introspection) at the beginning of the study. For the record, I am of a sound mind and have never experienced auditory or visual hallucinations in my life (not even when I tried LSD in my youth).
I will characterize visual qualia using five parameters: 1) KIND (e.g., geometric shapes, people, things); 2) ORIGIN (e.g., location in the visual field, the way they appear, intentionality); 3) DURATION (estimated in seconds); 4) COMPLETENESS (e.g., entire objects, pieces of objects); 5) STABILITY (e.g., the degree to which they change in appearance).
These are subjective data and are based on memory. I will try and keep notes in the future. However, they aren’t subject to much change from one introspection session to another. There are probably some I missed.
KIND. Only objects were perceived. No landscapes, or movies, etc. They consisted of people, cars, geometric shapes, animals (cattle, bizarre chimera), unidentifiable objects reminiscent of totem poles, and colored blobs. There were also monstrous apparitions like deformed heads (see STABILITY below). The background was consistently black. The colors varied widely, with many bright hues, but also deep shadows. All objects were in sharp focus. No fuzzy edges. Colors for human and identifiable animal skin were normal. I didn’t notice any textures. The visual field contained more than one, often many, objects simultaneously.
ORIGIN. Most objects were moving, sometimes towards me and passing out of my visual field as if going past me. Other times they took the opposite trajectory, and passed me as if on a highway. All trajectories were straight with constant velocity. Most moving objects within a time frame of 1-10 seconds had the same velocity and trajectory. A few, mostly people and animals, appeared in the center of my visual field and didn’t move.
DURATION. No individual object remained within my view more than a couple of seconds, depending on velocity. The fixed objects were unstable and morphed (see STABILITY below).
COMPLETENESS. Nothing was complete. Some aspect of every object was missing. For people and animals, there might be only a head, sometimes with an irregular hole centered on the nose, sometimes one side seemingly melted away. The same applied to the animals. Pieces of cars consisted of grills, fenders, etc, but no complete cars. The blobs were smoothly irregular with no holes.
STABILITY. Any object that was either stationary or moving slowly transformed into something else, often radically different. For example, a human head melting and wobbling as it turns into a monstrous apparition. However, I don’t recall any animate object turning into an inanimate object. Nothing remained the same for more than a second. Even the transforming stationary objects dissolved within a few seconds, to be replaced by something moving through the visual field. Collisions caused morphing to occur, but mostly between moving and stationary objects. Moving objects did not collide with each other. It was like the Cirque de Soleil on steroids.
In the next post, I will discuss these anomalous visual qualia in terms of the TOSCA model and show their relevance to the objective of the blog – seeking a state of enlightenment through the Dao De Jing (The Great Way).
The next few chapters are going to focus on visual perceptions, but not of objects in the physical world. That will come up eventually but as part of studying the Dao De Jing, I am more interested in introspection. For example, here is a quote from DDJ 16:
“Attain the utmost emptiness, secure unbroken stillness. The myriad things arise together and we watch their return. Though they flourish in great numbers, each returns again to the source. Returning to the source is called ‘stillness.’ Stillness is called ‘returning life.’ Returning life is the meaning of constancy. To know constancy is enlightenment. Not to know constancy risks disasters.”
This quote discusses the relationship between the myriad things and the objective of this blog — enlightenment. In other words, enlightenment is a state of stillness, in which the creation and destruction of the myriad things (defined in Chapter 1 as expressions of the tripartite body-mind system that comprises us as individuals) is accepted as natural. They shouldn’t distract a person from more important matters.
The previous chapter introduced the concept of qualia, but now I want to explicitly state that the myriad things (and myriad beings) referred to in the DDJ are qualia in the TOSCA model. These are built from packets traveling the virtual network that permeates our brains. These packets are constructed of bytes, which are composed of bits, which are individual neurons (and what state they’re in – on or off). This chapter discusses visual qualia that originate from within the body-mind system.
Everyone dreams and most of us remember at least something about our dreams, which usually involve visual images, even if only poorly recalled. There are several reasons for this: the hippocampus (which moderates the transfer of data from short-term to long-term memory) changes its functioning when we sleep; neural transmitters that promote memory formation have different concentrations during sleep; dreams occur in a mental state similar to mind wandering, and thoughts simply aren’t recalled in that state (a good reason to write down epiphanies immediately). Those completely imaginary visual images in our dreams are qualia.
Dreams are of no direct use in applying the TOSCA model, however, because even though we are conscious when we sleep, we have no control over our thoughts. We turn instead to visual qualia that we perceive when we are awake and able to take some kind of action. (See The Mind’s Eye.)
I’m going to interject my experiences with creating visual images to set the stage for the discussion. Books about psychology and neuroscience often have visualization exercises, in which the reader imagines, for example, a red letter, or some kind of image like a boat, etc. I tried to follow along but could never see the image, but only imagined it and manipulated it following the instructions and understood the exercise. But I never saw anything. I ignored this discrepancy and assumed it was simply a case of ambiguous words – semantics.
I’ve been practicing meditation (actually introspection with a metaphysical label) and sometimes I would sit quietly with my mind as blank as I could make it for up to thirty minutes. I had always ignored the strange images I would sometimes see after about ten minutes. It didn’t always occur, so I assumed (again) that they were random images from memory. I read about this phenomenon and discovered that creating mental images is quite common, so common in fact that researchers invented a name for people with no ability to see with their mind – Aphantasia. It hasn’t been investigated much because (apparently) the psychologists who study vision and brain function are quite familiar with the phenomenon. (They must have assumed that everyone was like them.)
What these two experiences imply is that I can’t intentionally generate visual qualia. And I’m not the only one. Conversations on the topic are obfuscated by not having a clear definition of a mental image. The mind’s eye is a catch-all phrase for imagining something, whether descriptively or visually. This leads to dividing visual qualia into two types: descriptions that can be thought of as a list of characteristics (often very detailed) of an object; and actual visual images created in our visual cortex and passed to…wait a minute – just where is consciousness located?
There is no answer to that question, but recent work has found a link between the brain stem (most basic part of the brain) and two other regions in the cortex. As I said in describing the virtual network within our brains, it is distributed and that applies to everything else, including consciousness. So, the images created by separate visual processing circuits in the two halves of the brain (the left-brain processes the right visual field from both eyes, and vice versa) are sent along the VN to be constructed as qualia by the distributed consciousness system.
The next chapter will discuss how these qualia might be perceived through personal observations. The data are necessarily subjective in this kind of study, so I’m going to be using myself as the test subject.

The Tripartite Organismic Stimulus-Response Cortical Augmentation model (TOSCAM) consists of four components so far: the human body; the subconscious; the conscious mind; and as-yet undefined stimuli, which I temporarily referred to as qualia. This post will explore this last component in more detail.
I did some more reading and discovered that perception is conceivably more complex than simply seeing or hearing something. Philosophers have constructed many theories to try and understand what we see, etc., including the physicalist model, which (greatly simplified) proposes that nothing is going on in our mind. A signal, like the light spectrum from an object we are viewing, is processed into a series of neurons firing and sending a representation of the object to our prefrontal cortex, where it is perceived as it really is. That sounds pretty straightforward, but someone pointed out the existence of hallucinations and other phenomena like phantom limbs, that aren’t representations of anything a person is experiencing. One concept that grew out of this discrepancy is Sense-Datum Theory.
Vastly oversimplified, Sense-Datum Theory proposes that sense data consist of both content and intrinsic non-representational features (e.g., blobs of paint comprising a painting). This latter signal is what is called a quale (qualia is the plural). Unfortunately a quale can’t be measured and is nothing more than a hypothetical construct, so there’s a lot of controversy associated with the idea. For example, many philosophers treat it as the sensation of perceiving (e.g., how does it feel to “see” red).
Here’s an interesting summary from the Stanford Encyclopedia of Philosophy (see note 3): “…we still seem to be left with something that we cannot explain, namely, why and how such-and-such objective, physical changes…generate so-and-so subjective feeling, or any subjective feeling at all…Some say that the explanatory gap is unbridgeable and that the proper conclusion to draw from it is that there is a corresponding gap in the world. Experiences and feelings have irreducibly subjective, non-physical qualities…There is no general agreement on how the gap is generated and what it shows.”
To muddy the water even further, here’s another interesting comment on qualia as representational: “If I feel a pain in a leg, I need not even have a leg. My pain might be a pain in a phantom limb. Facts such as these have been taken to provide further support for the contention that some sort of representational account is appropriate for qualia.”
I was going to drop the concept of qualia in my model and instead use a concrete word like sense-datum as the information-carrying medium for perception and let the philosophers argue about the details. However, I’m not going to be publishing my model in any peer-reviewed journals and I like the idea of a simple word rather than a phrase. I’ll keep qualia with the caveat that it is being used in a representational sense. I accept “some sort of representational account” as good enough for my purposes.
Without espousing Sense-Datum Theory, I am going to use the following definition of a quale (actually a sense-datum): an immediate object of perception, which is not a material object; a sense impression. I’m only using the concept, not the theory. In fact, neither quale nor sense-datum are very useful because they leave us with a vague concept of something we are aware of (perception) and not how the perception was created. How is a quale (sense-datum) created? (I’ll use the parentheses in this post only.)
Let’s think of the brain as a computer network. This is an old idea and it isn’t particularly applicable; after all, there are no main network cables within our heads but instead trillions of axons connecting every neuron to practically every other neuron with an uncountable number of intermediate neurons between them. We can get around this gross oversimplification by introducing the idea of a virtual network. For example, perceiving an object (philosophers like to use tomatoes) is the result of a complex process that turns the electrical signals from over 100 million rods and cones into an image, which is then identified, cross-correlated, and delivered to our prefrontal cortex, ready to be acted on. We may cut the tomato up or put it in the refrigerator for later use. However, those millions (who knows how many) of neurons are firing synchronously to deliver the total package of what we perceive as a “tomato.” I’m calling this organized firing of millions of neurons a virtual network (VN). A virtual network isn’t static. For example, here are some neural frequencies during different mental states.
|Beta (β)||12–35 Hz||Anxiety dominant, active, external attention, relaxed|
|Alpha (α)||8–12 Hz||Very relaxed, passive attention|
|Theta (θ)||4–8 Hz||Deeply relaxed, inward focused|
|Delta (δ)||0.5–4 Hz||Sleep|
These data suggest that any given VN (say, that associated with looking at a tomato) is at risk of being deleted as often as 35 times per second, and at best lasts a couple of seconds. Obviously, we can hold a thought or perception longer than this; what this implies is that any specific quale (sense-datum) must be refreshed or updated continuously or it will be replaced by something new (perhaps a carrot lying next to the tomato).
To complete the network analogue for the TOSCA model, we need to define qualia in more detail. The digital model of bits (binary device that can be on or off, 0 or 1, etc.) seems appropriate to describe the smallest unit of information transfer among neurons, which are either on or off. Some arbitrary number of neurons firing in unison as part of generating a quale (sense-datum) is somewhat analogous to a byte for the TOSCA model. In most computer applications, a byte consists of eight bits. This is the smallest unit of storage in computer memory, but we don’t have that restriction in the brain. Nevertheless, it is a useful concept because a byte is not sufficiently large to generate the perception of a tomato. For example, a few dozen neurons (bits) could form a byte that contains information only about the color of the tomato, and other bytes would encode other characteristics (e.g., location in space, roundness, softness).
To assemble a quale (sense-datum) for the perception of an object, thought, emotion, etc, we need to organize all those bytes coming in from millions of neurons over the VN. This can be done using the concept of a packet borrowed from digital networking. A packet contains both data and information about how it should be decoded, a perfect idea for the model. For example, groups of bytes can be virtually organized into packets that contain shape information, etc, and telling the receiving part of the brain (e.g., the prefrontal cortex) which ones go together. No one has a clue how this is done. It is an abstract concept even in brain research. We only need the concept to continue; and with the idea of multiple packets arriving from different brain areas with information about what they contain, a quale (sense-datum) can be perceived.
This has been a moderately technical post, but it was necessary to have a complete concept for the TOSCA process before applying it to real-world examples. The next post will focus on visual perception and how it can be studied, using introspection to examine and control qualia, or sense-data.
