Some Thought Experiments

Our local Faith and Science study group has recently spent a lot of time discussing psychology, mind, and consciousness from various perspectives. It is clear that there is a wide range of views on these subjects, and that, while scientists have made great strides in neurobiology, brain structure and mental functioning, the "hard problem of consciousness" remains a profound mystery. Indeed, even defining what constitutes "consciousness" is fraught with difficulty. 

I will not resolve any of these aspects, of course, but from pondering our studies, I have collected some ideas about what individuals can do to explore their own consciousness. Not to worry, none of what follows involves danger, drugs or otherwise major changes in consciousness. These are simply ways to look at how you remember your past, to collect words about how you think, and to try out a few exercises in self-awareness; that is, exploring your mind by thinking about thinking. I hope they will help some get a better grip on their own thinking processes.

1. Remembering the Past:

Thinking about events from your past, choose one that is clear in your mind, not too positive or negative, yet memorable. How are you recalling it in your mind? Is it verbal, as in speech or words, or is it visual as in a still image or a short movie sequence? Some people are verbal thinkers and some are primarily visual, while others mix these modes. As you recall this event, where are you in the memory? Are you experiencing it first person - through your own eyes or ears - or do you see yourself in the third person, as someone hearing or watching you as it happened? Here too, different people perceive their memories differently.

Most people are aware that our own memories are sometimes deceptive and play tricks on us, leaving us feeling unsettled, especially when the memory seems so clear, although proven wrong. Next time you are corrected or discover your memory error, think about what precisely you remembered wrongly, and where might that error have come from? Were you making it up as in wishful thinking, filling in a gap between the parts that are correct, or did you truly believe it happened that way? For instance, I have a lousy memory for verbal exchanges. I rarely remember the actual words, but think I have the gist of the conversation. Then someone will correct my faulty understanding, revealing my inner assumptions or preconceptions. 

How much of your own memories do you think are accurate, and how do you know? Most of us have (seemingly) good memories for some things, and poor memories for other sorts of things. In my case, I remember concepts and numbers that were relevant to my career, but am terrible with peoples' faces and names.

2. Searching Your Mind:

Speaking of memories, how do you find yours? Do past events come back instantly in full detail, or do you have to dredge them out slowly by bits and then piece them together? As you go over the memory, do further details fall into place, or do they seem utterly lost. Does a photo of the place or event trigger more details or associated memories? When someone else is recalling a shared memory, does that improve yours for the same event? When someone mentions a memory you cannot remember, but should, do you somehow search around in your mind for it, or try to tie it into something you do recall?

How do you proceed with a memory search? What does it feel like to search your brain for something?  What is happening in your mind or head as you search? Do you talk to yourself? Do you see your memories as a library or disk drive you are searching through? Or is it more like a cluttered, dingy, dusty basement, with random stuff piled up and fading off into the distance. Is there some method to your searching or do you just mentally browbeat yourself trying to force out the memory? Do some approaches work and others not so much? Putting words to your mental processes can be difficult but also, perhaps, revealing.

3. Word Searches:

Everyone searches for words at times, especially when trying to compose something in writing. The worst is struggling for a word while in conversation. The thoughts come together into sentences and roll out of your mouth smoothly, until you hit a mental block and are left hemming and hawing hoping the correct word will come to mind. While typing or writing, you might get stuck suddenly, knowing there is a word for the concept you're thinking of, but unable to recall it. You can think of its definition, and maybe even some similar, but not quite right words, but the right word remains hidden from your mind. You press on as best you can, perhaps using other words, but later, the word will pop into your head, often unexpectedly. How does that happen for you? And then, is it actually the correct word you were looking for, or does it turn out not to be quite what you wanted? 

What mental process do you go through while searching your mind for the elusive right word? How do you dig around in your mind for a particular word? You know that you know it, but somehow cannot bring it to mind. It is hidden somewhere in your subconscious. Think about how do you know that you know the word even if you cannot "find" it? Do you have clues, such as begins with a "c", or do you get stuck cycling through "it's sort of like this" thoughts? Then does it seem close "on the tip of your tongue" and then slip away again? What does that process and your progress toward remembering say about your mind and its mental processes? Then, what feeling or "aha" thought comes when the word magically appears in your head again? Is it a happy rush, "ah there it is", or an "of course, dummy" thought? What do you do next if you are away from the work that needed the word? Do you subsequently forget it and have the same difficulty recalling it again?

4. Mental Development:

A lot can be learned about psychology by observing child development, either from your own past, or by observing yours or others' children - how they learn and do things, like observing, controlling their hands, crawling, talking, walking, etc. New-born babies must be born scientists, observing the world they come into, then automatically formulating mental models or theories about that reality: what are those things waving around before me? Oh I can control them, making them move (my hands). Or how to understand all those contrasting colours, lights and shadow edges and how they change (the room around). Then there are the sounds, some of which seem familiar from earlier (in the womb), others repeated, but so many new. And then feelings of pain, pleasure, contentment, discomfort, etc. So much to perceive or experience and then to integrate.

Each child's mind has to figure out what to make of all this, putting it together into a complex set of overlapping models about reality that they can use to understand their expanding world and to develop further, with additional inputs and correctives. Later on there is the example of children learning to talk and form sentences. For instance in English they learn that past tense words end in the "ed" sound, so initially the past of "go" becomes "goed". Only later, with feedback, do they learn "went" and other irregular verbs. Can you think of any other aspects of child development that reveal something about how their minds work? Sometimes the adults around the children can almost see the gears turning in the child's head as they think through some concept or new datum. As you think back to your own childhood, do you remember any times when you had an "aha" thought about the world around you or your relation in it? Or how about having a firm idea about something that later proved false?

Still thinking back to your own childhood. What are your earliest memories? Are they visual and/or auditory? Is there action and/or dialogue? Are the memories complete, or just a few vague perceptual wisps or emotional content? Indeed, are they actual memories, or are they maybe just memories of memories, of your previously having remembered them? How "real" are they to you now? Are there feelings associated with those memories, and do you still feel those? Do you still interpret or understand the memories as you first experienced the events, or have you adjusted how you see them, based on later maturity and understanding about them? 

5. Thinking in Your Sleep:

Dreams have been studied at length by psychologists and non-scientists for centuries, and there are numerous theories on why we dream and what our dreams mean, if anything. Our dreams usually fade upon wakening. How does that feel like for you as you wake up and notice the dream slipping away? And if you want to remember a dream, how do you mentally capture it so that you can remember it well enough to share later? What do your dreams mean to you? Do you like dreaming? How coherent and logical are your dreams? Do they make sense during the dream, or even later when awake? If you speak two languages, do you dream in both of them? Are the other people in your dreams from your past or your present? Can you wake yourself up from a bad dream to stop it? Or perhaps you have lucid dreams - ones that you consciously control?

This raises questions about falling asleep and waking up. As you fall asleep are you aware of doing so, or do things just go quiet and empty and then you are asleep, unknown to yourself? Is it sudden or gradual, easy or difficult to fall asleep? Do you feel like you are losing aspects of your mind or sinking into a lower consciousness level? If something brings you back to consciousness as you are falling off, are you aware that you were asleep? On the other hand, when you cannot sleep, do you know the reason why or is it just not happening? What seems to be keeping you awake? 

In the morning, when you wake up, is that sudden or slow, does your awareness sort of gather and develop, come in pieces, or is it there all at once? If you wake up to an alarm or radio, does that first enter your dream for a few seconds, or is it instantly clear what is happening? When first awake, are you groggy and fuzzy-headed? If so what does that feel like and what do you do mentally to dispel it? What is in your mind during your waking? Do your dreams begin to mix with reality or do you slip in and out of consciousness, perhaps in part or at different levels? It's not easy paying attention as you fall asleep or wake up, but if you try, you might get some insights into your mind.

6. Learning Something New:

Learning a new or different skill or procedure - such as riding a bicycle - at first is somewhat difficult and needs your full attention, concentrating on every aspect. You make a lot of mistakes but figure out how to correct them. Then it slowly gets easier and certain aspects start to become automatic, and finally, habitual: you can now do them without thinking about the details. The question to ponder is, how does that work in your mind? What are the mental stages in learning something new?

People talk about "muscle memory" for physical skills, but mostly it seems when you learn you are somehow training your subconscious in this new task or set of actions. An analogy would be writing a software subroutine for your brain. At first you need to look at everything in detail to get each step right, then as you improve, pieces of it seem good and finished, while others need more work or correction (debugging?). Finally, the routine seems good and you store it away somehow below the conscious level, and set your mind on other things. When you need to use that learning again, it comes up and starts to work, running smoothly with little conscious effort, especially if you have used it often. Of course the mind is not some software operating in the brain's hardware (or wetware), but it is an interesting analogy. Think about how you consolidate and settle some learning or practice. How does that proceed for you?

One clear example is driving a car. After years of doing so, it seems almost automatic, requiring no conscious effort. The next time you are driving along a straight highway, look down and watch your hands on the steering wheel. Are you consciously controlling them or do they just steer the car by themselves? Of course you shouldn't try this, but if you were to close your eyes for a few seconds, what would your hands then do? Clearly there is a feedback loop from your visual perception of the vehicle's position and direction on the road, to your hands constantly adjusting the steering wheel to maintain a steady state. Just as clearly, that feedback loop does not pass through your consciousness. Indeed, if you consciously tried to control your hand motions, you would likely become a danger on the highway!

While driving normally, you can engage your conscious mind in totally different activities such as singing a song or holding a conversation with your passenger. Indeed, there have been times when I was so engrossed in a conversation that I drove right past my highway exit. It seems that my conscious route planning forgot to set an "interrupt" for my subconscious driving. Other such "interrupts" that bring driving back up to the conscious level include a sudden stoppage up ahead, a funny noise from your motor or tires, or a pinging from your control panel. In such ways the act of driving shifts up and down through the layers of your consciousness.

This process of learning something new and then committing it to subconscious behaviour is, of course, essential for humans. It would be impossible to live if every perception and action response had to be consciously managed and initiated. Yet aside from a few basic non-conscious abilities, almost everything we do every day was learned at some point in our life and most of it has been committed to our subconscious. Our conscious thinking then makes decisions - such as what route to drive - and then sets some sort of supervisory routine, with suitable fail-safe interrupts, in place to keep track of what we are doing, while allowing our conscious mind to do something else. 

7. Non-Conscious Thinking:

Psychology teaches, and we have noted above, that a lot of mental activity (AKA thinking) goes on subconsciously.  However, psychology seems to have difficulty defining and explaining our subconscious, its differing levels, and the interactions among them and our conscious selves. We do many things by rote (unthinkingly) or while thinking about something else (e.g. while driving), paying little conscious attention to the fully automatic parts. We are largely unaware of most of the perceptions our brain receives constantly: those feelings in our body as we sit reading a book, the familiar background noises around us, the well-known visual surroundings at home as we do chores, etc. We are usually unaware of all the things around us that are "normal" to our minds.

There must surely be multiple levels of awareness or consciousness.  Some are fully automatic and we ignore them completely unless some sort of "interrupt" brings them to our awareness. Other levels are monitors or supervisory, working off in a "corner of our mind" to make sure the automatic stuff is going well, such as keeping to the side of the road while riding a bike. Some we watch for, ready to take action while doing other things, such as waiting for the light to change while stopped in our car. The conscious levels too may differ. Some are just going about our normal tasks, planning and sequencing what to do minute by minute. The highest level may be concentrating so closely on something that we tune out the other levels. 

Just as there are "subroutines" that you let your subconscious self perform, There may be other tasks you purposely delegate to your subconscious at some level. For instance, a problem worries you, so you decide to "sleep on it". Or you may consciously turn away from something disturbing, allowing your subconscious to process it so that you can handle it better the next time it comes to mind. What does it mean to bury something deep in your subconscious? How do you think about levels of consciousness in your own mind. Are they distinct or is it a continuum from totally unconscious up to full concentration? 

8. Streams of Consciousness:

Sit or lie down in a quiet place, away from distractions. Quiet your mind away from urgent or current issues, relax, close your eyes and just let your mind wander. Where does it go? After a few minutes, stop and then "rewind" and recall where the stream took you. Do you track this stream from the start, or backwards from the end, or out of order? Is it easy or hard to remember what you were thinking? Then, think about the changes or shifts in the thoughts during the stream. What caused them, did you consciously shift back and forth or did they just happen? Did you leave loose ends behind and move on, or complete some other thought first? This exercise could be the start of meditation or introspection: thinking about your own thinking.

From a different perspective, when you are concentrating on a task or some demanding mental activity, do you get distracted easily, or do you get so far into it that you lose track of what is around you? Perhaps both of these apply at different times? What is it that distracts you or draws you out of your reverie? Can you learn (i.e. teach yourself) to be less distracted? Does practice in concentration help you do it better? 

Alternately, when focused on a task that is not going well, like worrying or waiting frustrated, try distracting yourself by consciously thinking of something else, perhaps something pleasant like a memory, or more enjoyable task. Is that easy for you to do? Can you be in charge of where your thinking goes in a controlled and chosen way, or does your mind seem to go where it wants regardless of your will? How well can you discipline your mind? What does that even look like?

Here is a mental exercise in consciousness control. While sitting or lying still - it may help to reduce distraction by closing your eyes - focus your attention on one part of your body, feeling any sensations from there: the touch, warmth, any little pain or pressure. For example, can you zero in on the 4th toe on your left foot and hold your awareness there? Can you then shift your attention to your right shoulder? Is there any part of your body, internal or external that you cannot access in this way? And how closely or narrowly can you focus? Sweeping your conscious awareness in this way, from the top of your head, slowly down through other parts of your body to your toes, is one way to relax, feeling the tension and stresses flow away. This can also be an effective tool to shift your awareness away from a painful part of the body. By focusing on the normal feelings elsewhere, minor aches and pains that bother you may seem to fade to insignificance or become more tolerable.

9. Language and Consciousness:

The connection between consciousness and language is fascinating. Some people seem to always have a running commentary in their head - talking with (or to) themselves. Some psychologists think that language is essential for consciousness, but that may be too simplistic, especially if they don't say what they mean by "consciousness". Other people seem to think in images, "seeing" plans and actions unfold in their minds ahead of time. For example, anyone who knows internal combustion engines, upon hearing the word  "crankshaft", will get an instant image in their mind, whereas it is not easy to describe one of those in words. What sorts of non-linguistic thoughts do you experience? Do your mental images come with word labels or verbal descriptions, or are they silent in your mind?

When washing dishes, we don't usually think to ourselves, "pick up brush, scrub plate in this way, turn on rinse water, place plate in rack" and so on, we just do it. We are conscious that we are doing it, while thinking other thoughts verbally in our head as we proceed: singing along with some music, carrying on a conversation, or worrying about your kid being out late. Presumably the dishwashing (once you have mastered it) is non-linguistic thinking somehow. But can you think consciously without anything verbal going on in your head? Can you choose to do that or does it just happen in between other thoughts? Can you consciously turn off your internal dialogue? Can you be conscious without language? 

10. Musical Mystery:

Psychologists are intrigued by how music makes memories so much stronger and easier to remember. While memorizing a prose paragraph is usually difficult - a task high-school students hate - most of us can remember the tune and lyrics of songs from decades ago, without even trying hard. Even songs we didn't care for or may only have heard a few times pop into our heads and we can sing parts of them. Somehow the tones and rhythms of music augment the memory process. This association has apparently been used by some to improve their memories. 

It seems that most people can remember significant parts of more than a thousand songs they have heard in the past. And most of us have had the experience of an "ear worm"; a song that comes to mind and then won't leave us alone! It turns out that our musical preferences are usually set in our late teens and early twenties - perhaps one reason why older people don't like current music styles. It seems likely that most of the songs you remember forever were learned before you were 30 years old. Is that true for you? What is the earliest song you learned and still remember?

11. Changing Consciousness:

Have you ever experienced "altered states of consciousness" or any sort of "raised consciousness"? Some people have had such experiences, with or without help from drugs, meditation, etc. If so, how was it for you? Can you describe it to yourself or to another person, or was it so enigmatic and ethereal  that words do not suffice? Or maybe you forgot what it was like as soon as it was over?

If you have not had any such experience, you could still try to observe yourself when drunk, high on drugs, sleep deprived, or excited about something. What can you report about that state of mind? Were there changed perceptions, different thoughts, a new outlook, or any supposedly "mind opening" aspects to it? Were those true changes or just shifts in perspective? Could you remember them clearly afterward or did they fade? Clearly chemicals, environment and various situations can change our consciousness: fight-or-flight reaction, adrenalin rush, oxytocin / dopamine / serotonin / melatonin, etc. each can affect our mood, feelings and attitudes, and hence, our consciousness as well as behaviour.

12. Philosophy of Mind:

To wrap up this post, what is your philosophy of mind? Are you a brain that thinks ("mind is what the brain does"), or are you a mind with a brain (mind is more than the cells in your head)? This gets into deep metaphysics, but is worth thinking about. What about the mind-body duality? Is your mind separate from your body or just the thinking "wetware" part of it? Do any of your thoughts come from elsewhere? E.g. gut feelings, ancestral awareness, insights from the blue, dreams, or even cosmic consciousness. When all is written and talked about it, consciousness and the human mind remain a profound mystery. 

Each of us is free to explore our own thoughts and conscious processes and draw our own conclusions. Many more mental exercises could doubtless be appended here. Can you think of any additional ones yourself? It is interesting to delve into how we think and how the mind behaves under normal and novel conditions. Did you learn anything in reading this, or was your consciousness "raised" in any way with these exercises? In any case, I hope some of these experiments and descriptions helped you understand yourself a little bit more.

Aspects of Consciousness

Awareness, mind, sentience, thinking, perception, introspection, self - all that we group together as "consciousness" - are fundamental to human beings, but consciousness is a difficult subject to define, measure or specify in a coherent way, although attempts have been made to do that. Just defining the word is fraught with controversy, uncertainty and more than a little confusion. Some want to define it narrowly, as Julian Jaynes does in limiting it to introspection alone: thinking about thinking, or thinking about your own mind and thoughts. Others want to define it broadly as panpsychism, in which everything - even a rock - is "conscious" to some degree. There are even some materialists who claim that consciousness is just an illusion! However, I expect most people are more reasonable, knowing what they mean by being conscious, even if they cannot define it precisely.

Beyond knowing what consciousness is and how to reasonably define it, there is the "hard problem of consciousness", being able to understand it and how we humans can be conscious in the full sense of self awareness and being a thinking agent in the world. Part of the problem is that consciousness involves numerous different aspects of brain and mind activity, many of which are themselves poorly defined, overlooked, or misunderstood. Some claim that the "mind" is what the brain does, while others find evidence that the mind is dualistic, at least partly a separate entity - the "soul" if you will - and merely uses the brain to act as its location and interface for agency in the body and the external world. 

Having recently read a lot about the mind, artificial intelligence, consciousness, and being human, I began to collect aspects of consciousness in an attempt to wrap my head (as it were) around the concept and thereby, somehow, better understand it. The following is my collection of processes or mental activities that can be considered aspects of conscious experience and behaviour. I have attempted to group these into some semblance of logical categories:

Sensation:
This is receiving the signals arriving from your senses:  sight, sound, touch, smell, taste, proprioception, etc. These come into our brains all the time, but are often (usually?) not noticed or acknowledged by our minds. E.g. the nerves in my backside are constantly informing my brain about the pressures and temperatures they sense while I sit here typing, but I rarely am aware of them, much less pay attention to them. Typically, I take notice (become aware) only when there are unusual changes.

Awareness:
This is the next step in perception, taking in and recognizing what comes through the senses or your body: visual images, hearing voices, pain in your toe, emotions, and so on. For instance, I am vaguely aware of the sound of the air circulation in this room, the light coming in through the window, and other peripheral inputs, but here too, they do not usually impinge on my thinking.

Attention/Focus:
Here now is where we apply our minds to the perceptions we become aware of, paying attention to some aspect of your awareness in priority over most of the rest. This may be intentional, as in looking out the window and evaluating what I see there. Or it may be like an interrupt routine, where some perception suddenly changes and you react by focusing on it to see what happened or if you need to respond. The air flow stops suddenly, or there is a cold feeling in my seat. Those are usually dynamic, or a change that rises to the level of awareness, and somehow triggers your brain to get the mind involved. The triggers probably arise from your subconscious, which is monitoring much of the sensations, and raises a flag or interrupt to your mind as an awareness, allowing your mind to focus on it. The interrupt may be gentle as in a persistent itch, or may be very high priority as a sudden stab of pain in your back or knee.

Feelings/Emotion:
These are the internal, mental sensations as it were, because they originate within the brain or the mind itself. This includes all the emotions at a reasonable level: pleasure, hurt, disappointment, sorrow, anger, joy, hope, etc. It also includes feelings like depression, excitement, expectation, comfort, boredom, etc., which are different from feeling a touch or coldness and other external senses. Here too, there may be numerous emotions and feelings floating around my person at a low level, at any given time, only one or a few of which I am aware, yet they are present if I pay attention. For example, I may recall that I'm still upset about something that happened yesterday, but I put it aside to think about (pay attention to) something I deem as higher priority.

Concentration:
This is the highest level of consciousness regarding perceptions and attention. In this mode, you apply most, if not all, of your conscious attention and resources to one perception and its correlates or consequences. That flash out the window might be an explosion or lightning; better pay attention, investigate, decide what to do and initiate action. During this event, all unrelated perceptions, attention, thoughts and activities are side-lined or put on hold as you deal with the highest priority. This also applies internally, to deep thinking, focusing on a task or issue, or dealing with a strong emotion that takes over other aspects, shifting other awareness to the periphery. An example of that is focusing on doing a Sudoku puzzle to the point where you only realize you leg is stiff after completing the puzzle.

Understanding:
This is the internal, mental aspect that goes along with awareness; e.g. knowing what you are looking at, understanding the words on the page, hearing what your neighbour is saying, identifying that smell, realizing that you are angry or tired. Your mind has engaged with the sensations and perceptions or your own internal thoughts, to extract sense and even meaning from them. At one level, I can glance at a page in a book and realize ("understand") that there is a block of print there. At the next level, I can focus on the print, see that it is in English, and can read it, knowing each of the words. Then I can understand what I'm reading; what the words mean and how the sentences flow, imparting information to my mind. My mind is then thinking about what I am reading.

Interpretation:
While understanding as described usually does not require much focus or attention, taking it to the next level does require thought and application of other mental resources. To deeply understand or to gain knowledge and learn requires that we interpret what we see, hear, read or feel. And that involves connecting the initial understanding with your mental model of reality to see what it means at a deeper level, or to you personally. Does what I'm reading fit into my prior understanding of the subject? Is it coherent and meaningful? Does this new information change anything for me? 

Reasoning/Processing:
This is perhaps the first level of truly human mentality. Most higher animals can do the above aspects in their consciousness - setting aside the "reading" example. Any dog or cat can assess its perceptions, understand and interpret them from its own perspective, then concentrate on and take action regarding them. Reasoning, however, is the further application of organization and logic used to draw conclusions or make surmises about something being thought about: deduction, induction, speculation and hypothesizing. Some animals can do this at a low level, but it takes a human mind to fully do it, and even then we make mistakes. This aspect is what is used to solve puzzles, do your homework, follow a complicated script, argue a point, work out an explanation, etc.

Analysis/Calculation:
This is perhaps a higher level of reasoning: applying learned tools to study and process received data of any sort; for example, mathematics, comparative inference, balance of probability, fitting to known facts, etc.  This level requires more mental resources than mere reasoning or normal processing. Some of this is algorithmic, how to do long division, writing code, translating a foreign language, etc. We may feel these are more like "hard work" as we have to apply a lot of mental effort to get where we want to go. The more involved, or novel the task at hand, the "harder" it may seem, and the higher the probability of making a mistake. 

Recall:
Now we shift into the information and memory aspects of consciousness. Recall is pulling facts out of memory: words, names, meanings, identifications, knowledge about reality, etc. all without a time stamp. Recall is one of the resources needed for almost all mental activity; putting names to perceptions: that is "snow", this is "hot", "things fall down", Joe is my friend, and so on - everything you know as simple factoids. You aren't born knowing all these, but you have learned them and your brain keeps them available to support your thinking and mind. These are memories that raise frustration when unavailable; e.g. "I know there's a word for X but I cannot think of it", or "What was the name of that person I met last week?"

Remembering/Reviewing:
This goes beyond simple recall by applying a personal time-stamp to the memory, your own life path/history, and recalling sequences of events known to you, or taken from someone else, as in remembering the plot of a story you heard, or the course of a news story you read. This aspect requires putting recalled information into some sort of temporal (or causal, logical, numeric or other) order for consideration in your mind. Psychologists differentiate between short and long term memory, but in terms of conscious activity, both are used in the same way, I think.

Narrating:
This is the next step in remembering; putting together and presenting a coherent story; e.g. of a dream, a childhood event, yesterday's meeting, or the plot of a book or TV program. The remembering is combined with processing and reasoning to make for a proper story, and then translating it into language and acting it through to actually present it, even if just in your own mind.

Planning:
If remembering looks to past reality, then planning is the opposite, preparing and putting together a sequence for possible future activity to make it become reality. Planning, of course uses recall to piece together credible possibilities, and uses time-sequencing to fit them into a causal chain of practical events. This may be brief and simple as getting up in the morning - often a repeated plan (a routine) - or it may be complex and long term as in planning your next business venture.

Learning:
This necessary aspect is the gathering of and grasping meaning from new perceptions, information, ideas or facts, and adding them into your memory. Much of this is done unconsciously, or automatically, of course. For instance when you go for a walk in a new area of town, you can easily (we hope) retrace your steps without too much thought. Some of it is straightforward, as in learning what your spouse did at work today. Some of it is abstract, as in retaining the conclusions of some task you performed in order to apply it to a different task. Some of it is slow but deep ,as in learning to ride a bicycle - almost like a subroutine that your mind assembles to store in your subconscious for almost mindless use once you've learned it well. Learning applies some of the above aspects of mental work to generate and save the results for future usage. 

Modelling:
This is a key aspect of any serious mentality. This is the collecting, assembling, adjusting and maintaining your mental image and understanding of reality; integrating new data into your world-view. Much of this is done subconsciously, of course, but your mind is constantly fiddling with or applying said model as you go through your day. Your overall modelling begins at birth as you discover your hands and how to use them, and how to interpret sensations coming from your eyes as an external reality. The modelling continues through life as you learn new things about the world and fit them into your reality. There is obviously a close connection to memory, but the model is the overall structure of your reality as you experience and perceive it. You know the layout of your house, street, workplace, etc. You know - for the most part - what is in your closet, how to drive your car, what happens if you open the door, who else is around you, what politics are happening these days, and so on. Your model is used in recall, understanding, reasoning, planning, and almost everything you do in your mind. It is an active, dynamic resource for who you are and all that you do. Our models are not always self-consistent, and models can be disrupted by new facts, as when I first learned that Pi is not equal to 22/7.

Relating:
This is presumably a higher-level mental activity that uses many of the above aspects for engaging thoughts about other people or things, toward communicating, understanding, empathizing, judging, analysing and interacting with them. "Theory of mind" fits here, as does listening sympathetically, or debating someone. Even simple conversation requires relating, and this can be done socially - with other person or persons - or individually, as in your head as an imagined or remembered conversation, taken in different directions. Other forms of relating include: prayer, using your cell phone's features, interacting with a pet, talking back to TV commercials, etc.

Action:
This is just your initiating movement - any bodily actions, including speech - via your mental activity to perform the action. As an agent, your mind needs to have agency; the ability to do something physical, to make your muscles move - the reverse of sensation. The actions may be planned or intended, but are often mere reaction like a startle reflex, or perhaps unconscious, as when coughing. Some actions, such as walking, are consciously initiated and guided, but otherwise subconscious - you don't mentally control your various muscles and balance mechanisms. Indeed, most of your actions are a form of subconscious muscular "subroutine" that you have learned and call into use when needed: talking, typing, brushing your teeth, eating, riding that bike. To see how programmed these indeed are, try doing them differently: using your other hand, a different keyboard, another language, etc. I don't recommend it, but trying to ride a bike with your hands swapped on the handlebars is a great example - almost back to square one in learning.

Introspection:
This is supposedly the pinnacle of consciousness: thinking about yourself, your mind and and your own thoughts; thinking about thinking - reflection, self awareness, self-image, every thought about your own mind and the "I" doing the thinking. This is entirely internal mental activity, but of course, uses many of the above mental aspects, and may result in changes to your reality, feelings, planning or actions. 

Stream of Consciousness:
This is the usually continuous, very subjective, mental flow of sensations, images, thoughts, ideas, words, feelings and qualia that we each experience inside our minds as we go about our day. It has been described as the movie of our life in which we are always the main actor as well as the audience. Most of the time we are in partial control as we go about our routines and plans, but most of the action is perception and unconscious routines that we take for granted. It is possible to lie down on the grass and look up at the sky and just let the stream flow where it will as thoughts come and go uninvoked. It is also possible to force your mind along a definitive path as when solving a math problem in your head. It is usually possible to "play back" the last few minutes of the stream by will and memory, as a form of introspection. It is difficult to have more than one stream at a time, although one can be paused in order to resume or begin another. And the stream may have multiple threads as when whistling and walking, while thinking about what to make for supper.

Verbalizing:
I wasn't sure where to fit this in, but it is another core aspect of consciousness: speaking internally to yourself, using language, as part of the stream of consciousness, or in preparation to speaking out loud (as an action). Some say that it is almost impossible for us to think without using language, although many animals appear to do so, and some people think more in images. Most people have a constant mental dialogue going on, sometimes with two or more parts when mentality thinking something through or considering alternatives - talking to yourself. When conversing with others or making an actual verbal presentation, of course, one is constantly planning or recalling (if memorized) the verbal sequence, which your subconscious then translates into actual speech. 

Meditation/Quieting:
This is essentially the attempt to stop or slow down the stream of consciousness; tuning out externalities while focusing (or emptying) the mind on something singular and simple for a time. One can focus on one's breathing or heartbeat, on a mental image or a single word, rejecting other perceptions and thoughts that may try to bubble up or impinge on the mind. This takes practice, I gather,  but it can be good for an individual to quiet the mind and take one's awareness away from the external world and any internal worries or concerns. In any case, it appears to be a distinct aspect of consciousness.

Aha!/Getting it:
There are some quirky aspects that come to mind for inclusion in this list. In this one, we have all had "aha!" moments when the facts and logic you have collected or worked through click into place and you feel a positive emotion of closure - usually short lived, but very satisfying. You "get it", you "grok", or suddenly understand the concept, idea or conclusion before you. This may be after a long time of concentration, or just as lart of learning as you go. It is related to but goes beyond "analysis", I think, and may be a very human thing. I wonder whether animals have Aha! experiences?

Obsessing:
This is a negative form of concentration, being absorbed by or focusing solely on one feeling, emotion or circumstance, beyond reason and (usually) to your own detriment: hatred, phobia, lust, pride, worry, narcissism, coveting - any of the seven deadly sins perhaps. We all probably do this occasionally for short periods. If it goes on too long, it may be a sign of mental  illness, perhaps PTSD, or past abuse. In severe cases, it is hard to pull the mind away from the feelings and surrounding thoughts. Your mind is stuck in a rut as it were and you are just spinning your wheels to complete the metaphor.


Clearly there are a lot of different aspects to consciousness. The reader may want to suggest others in the comments. There is obviously overlap among some of these and some readers may not like my definitions or examples. Readers may also see some of this as unnecessary hair splitting, but I think that distinguishing among these helps elucidate the differing applications of mental resources. As you go through your day, you might note which aspects you are applying at any given time in your stream of conscious activity. Does this form of introspection help you better understand yourself or others?

What is missing from all this is the mind itself, the "I" agent that is using the various aspects, the "self" receiving the perceptions, processing the algorithm, paying attention, verbalizing the thoughts. Above and on top of all these aspects of consciousness is the consciousness itself! This is the mysterious "me" or the acknowledged "you" that truly exists (cogito ergo sum!) but is hard to define and nail down. Yet without the self, all the above aspects are meaningless, do nothing, and serve little purpose. The mind or self is very real, and has lots of resources at its disposal to help it perform, but those do not define who it is, nor do they determine what thoughts occur within itself.

The core of consciousness remains a "hard problem" and a huge mystery: what/who am I? really!. Yet, I hope the above list of mental aspects helps you delve into your mysterious self a little bit. In closing, there is a whole other level to the mystery; the subconscious or unconscious part of the mind or self! Some people believe that is the larger part of the mind and its activity, all the parts below our conscious awareness - some as mentioned above. But that is a deeper subject going beyond todays' post.

A Reasonable Contrarian

Every public issue has two or more sides or viewpoints. Often, however, one side dominates and not always for good reasons. Ideology plays a big role, and the public narrative gets taken over by the loudest voice, whether or not the evidence and logic support that position. There are many issues in the news or floating around the Canadian context where one side has effectively been silenced by political correctness, the cancel culture, the supposed consensus, or other public power plays and pressures. In many cases, the other side needs to be heard, if only to balance the discussion and clarify the issue so that wise decisions can be made. 

I often find myself taking the minority perspective on public issues, sometimes at my peril. As a result, I cast myself as a contrarian. But rather than just being a curmudgeon against popular views, I feel that my views have quite reasonable arguments in their favour, which are often ignored, denied, dismissed, or insulted by those latched onto the official viewpoints and narratives.  I have written about some of these topics earlier, so will not repeat myself: evolution theory and Intelligent Design, global warming and climate change, atheism and scientism, capital punishment, the "gender gap" in engineering, the mainstream media, renewable green energy, and residential schools. Taken together, those posts should serve as my contrarian credentials regarding political issues and modern society!

But there are many other subject areas! The following are a few other issues on which I hold what may seem to be unpopular opinions. You may or may not agree with me, but reading the views of the other side is always a useful exercise toward better understanding. And in any case, surely I have the right to express my own views on my own blog without risking attack and cancellation? In no particular order then, here are some further contrarian positions explained briefly:

The Origin of Life:
The official status of OOL research is that science is making progress toward understanding the basis for life: the physics and chemistry, and biological processes involved. Multiple possibilities for how life got going on planet Earth have been proposed or are being actively investigated. Science publications hype up every supposed 'breakthrough' and will tell you that progress is being made and soon they will have a good idea about how life arose on planet Earth, and will be able to reproduce it in the lab. 

What they do not tell you is that most of the true 'progress' so far has been in finding out how many ways undirected, natural abiogenesis is impossibly difficult. Most reports on 'progress' are hypothetical theoretical looks at one aspect or other of the early Earth, of simple organic-chemistry building blocks, or other incidental aspects of the big picture - mostly just hand-waving speculation. Indeed, there has been no real progress toward creating life by credible processes using materials available on the early Earth. 

Some of the road blocks to true progress in this subject include: the chemical makeup of prebiotic Earth; the hard chemistry of forming suitable carbohydrates, lipids, amino-acids, and other necessary biological molecules; the total lack of homo-chirality (only left or right-handed molecules), which is needed for life; the natural unwanted reactions and thermodynamics  that work against biochemistry outside of cells; the difficulty of properly linking simple chemicals into the polypeptides and nucleic acid strings essential to all life; and of course, the total lack of any process to provide the vast amount of genetic information required for even the simplest protein, much less an credible protocell's DNA or RNA. None of these hurdles has been overcome in any credible lab research.

James Tour has done a huge service to explain these roadblocks, as well as to reveal and derail the biochemistry of pretentious OOL research in a series of YouTube talks. Another set of OOL refutations can be found here [?]. The bottom line is that science is farther away than ever from finding out how life could really have begun by natural means on our planet. Their search for spontaneous generation of life (abiogenesis) has come up short by several orders of magnitude. 

Abortion:
This was probably the original issue in the ongoing and ever-expanding culture wars! It has been in the news a lot recently, especially in the USA with the SCOTUS Dobbs decision, so of course, it has to be on my list here. The issue is polarized into two opposite positions: Pro-choice argues for women's "reproductive rights" and unencumbered access to abortion through the entire nine months of pregnancy, while the pro-life side argues for the rights and life of the unborn child from the moment of conception. Many people fall into one of these camps, but a sizable group - perhaps ebven the majority, properly understood - would like to see some resolution between these two extremes.

The pro-choice side - essentially demanding autonomy for women mostly for reasons of convenience - is pushed by feminists and numerous "progressives" with full support in the media, governments, medical establishment, universities and most other institutions. They dominate Canadian politics and public discussion. Meanwhile, biological science, long-standing morality, most religions and, many would argue, responsibility and decency, largely support the pro-life side. As a true contrarian, I have leaned toward the pro-life side for decades, but recently have shifted away from the conception end of the nine months of pregnancy. Thus, I disagree with both extreme positions.

Some time ago, I wrote a small book on the subject, Finding the Balance, which takes a scientific and logically reasoned look at the issue and comes up with an objective, quantitative way to balance the rights of the pregnant woman against those of her developing child in a fair and defendable manner. I won't divulge the results here; the book is available at a the lowest possible price on Amazon as a readable Kindle publication. See also my earlier post about the book.

Systemic Racism:
This topic exploded with the Black Lives Matter movement a few years ago. While no one claims there is no racism in North America, advocates of 'systemic racism' have gone to extremes to make everything about racism: microaggressions in every conversation, implicit racism in every public statement and public institution, violent uprisings in several cities, demonizing all whites as racists,  even calling out math, logic and science as inherently racist. This focus on racism has just made the problem exponentially worse in many people's minds, by polarizing society and identifying everyone first and formost by the shade of brown on their skin. Martin Luther King's progress against true racism has now been derailed by extreme ideological positioning.

In reality, and until 'systemic racism' became a thing, there was probably less racism in North America than at any previous time. Yes, there were long-standing statistical inequalities, and some subtle racist effects in society, as well as the usual outright bigotry from the few bozos, but overt racism had been on the decline for decades. Here in Canada, true racism was very rare, in my biased opinion. Such as existed was probably felt more by our First Nations peoples than by Blacks, Asians, or other visible minorities. However, with the claims of 'systemic racism' that situation has morphed into ideology, identity politics, and virtue signalling, driven by narrowly-focused social-justice warriors pushing their own agendas.

By various definitions of both words, you may claim 'systemic racism' exists, but it is pretty low level and hard to pin down in ways acceptable to most. From reports of overt racial discrimination elsewhere in the world, racism seems less of a concern here. Yet we now have newly racist policies to preferentially hire and seek out certain people based primarily on skin colour. Universities have racially designated processes, employers actively seek more visible minorities, whites are disrespected in some situations, and treatment is purposely different depending on one's race. While these changes claim to counteract past racist tendencies, they cannot help but be seen as codifying a different sort of stark racism.

Societal equality will never be reached (even if that is a meaningful goal) by forced inequality. Diversity, equity and inclusion (DEI) seem like good goals at first, but those ends do not justify the means being employed and will probably end up making the inequalities worse. So let's please back away from the 'systemic racism' trope and focus on true equality and fairness for all before the law, and in every institution, just as Martin Luther King and his followers wanted.

Euthanasia and Assisted Suicide:
This issue has been growing for a long time; another campaign by 'progressive' groups pushing the ultra-libertarian perspective of personal autonomy. Preceded by several European countries, Canada softened its position against assisted suicide a few years ago, pushed on by left-leaning courts and the mainstream media. The argument has always been that people in extreme pain from terminal diseases, with no hope of relief should be allowed to end their lives, and if necessary, to receive 'help' in doing so from willing medical professionals.

Such was the theory and there may be some moral and reasonable merit to that argument. However, that was just the starting point. Anti-euthanasia groups have warned all along about the "slippery slope" of assisted suicide, and time has proven them right. In Canada, it has not taken long for the law to be relaxed and amended to allow more and more cases of what is now referred to as "medical aid in dying" or MAID. The law now allows more people to be killed at their own request, from the disabled and mentally ill, to the depressed, to people just lonely or unhappy with their lives. And now there is pressure to extend MAID to sick children and even disabled new-borns, as if they can give informed consent to being killed. 

The slope has indeed been slippery as we approach the moral nadir of allowing almost anyone at all to ask to be killed. Not only does this go against centuries of moral and religious discouragement, medical ethics, and legal tradition, but it opens the gates for widespread abuse, notwithstanding the rules that are supposedly in place to prevent that - rules that often get bent or ignored as soon as they are signed into law. We how have hospitals suggesting MAID to patients who are expensive to care for, and to veterans of wars facing PTSD, as well as seniors who have lost their spouse, or people who cannot find suitable accommodations for managing their disability. Indeed, one of the arguments for expanding MAID is the savings in health-care costs that come from killing the patient!

Then there are the seniors who feel, often under subtle family or societal pressure, that they should just get out of the way, or that their life is meaningless now. When MAID is easy, this option will be taken more often, or even become normal or expected. Inevitably, however, mistakes are made, which of course, cannot be corrected after the fact. Moreover, some jurisdictions now require doctors and others to participate in MAID despite their personal ethical values against it, thereby undermining their freedom of conscience. On one hand, our society gets upset about drug overdoses and suicide attempts by young people, setting up hotlines and education for susceptible youth. Yet on the other we have now turned around and offer MAID to other people, including soon, some of those same youth.  

In my opinion, MAID was wrong from the outset. There are ways for doctors to sedate patients in severe pain, and if that leaves them unconscious or even hastens their passing, no real harm has been done. There is no need to kill people, even if that is what they supposedly want. Proper medical support and counselling usually improve people's quality of life so that they no longer wish to die, but you cannot give them that after they have been killed!

Darwinian Evolution:
Once life on Earth began, by whatever means, it is almost universally assumed that Darwin's theory of common descent, random variation and natural selection, fully accounts for the complexity and diversity of life we find around us today, as well as for the fossil record of extinctions and new species through the past billion years or more. The "neo-Darwinian synthesis", has been updated from Darwin's time to include genetics and other biological advances, and is the now the standard explanation in textbooks, science publications, and most media presentations.

Yet this monolithic perspective on "origin of the species" is, to put it bluntly, far from the truth. While the  Darwinian mechanism can explain minor shifts and adaptations in populations over time (like Darwin's famous finches), and simple mutational changes ("microevolution" such as antibiotic resistance in bacteria), it cannot explain major changes, new genetic information, and novel features in the creation of new and different species over time ("macroevolution" at the phylum, class, order and family levels). All attempts to apply the Darwinian mechanism analytically have come up short in terms of probabilities, credible processes, the available time, and the fossil record, which shows very few truly intermediate forms with gradual changes. 

The limitations of Darwinian evolution theory have been discussed and presented at considerable length for several decades now, and more and more evidence is accumulating showing the impossibility of new genetic code, new features in plants and animals, and any new families of organisms coming about through naturalistic Darwinian means. I have written about this in previous posts, (and here) and there is a wide range of material referenced there for those who wish to look into this subject. Sooner or later, the biological mainstream will shift away from Darwin's theory and be forced to look at alternatives.

Transgenderism:
If adults want to dress up and act like the opposite sex, that is their prerogative. If they do that well and can pass for the opposite sex in public, then let them do so and the public need not be any wiser. If they go further and seek drugs and surgery - at their own expense - to make them more like the sex they want to be, I will not stand in their way, but please don't ask me to knowingly affirm and encourage their gender dysphoria.

Unfortunately, here too, we now have a very one-sided narrative in the media and society at large, causing much confusion, disrupting societal norms, spreading public bewilderment, and even destroying more than a few children's lives. All manner of institutions have jumped on the 'trans' bandwagon for fear they will not be seen as sufficiently woke. People are being forced to use ungrammatical pronouns; men claiming to be women are gaining access into women's change rooms, sports programs, and even jails, with predictably disastrous results. Counsellors and even parents are legally prevented from advising mentally troubled youth and children against "transitioning". Children are being encouraged to doubt who they are, take hormone treatments and undergo mutilating surgery, only to become even more troubled, as well as permanently sterile and unhealthy. Any voices speaking against this seeming insanity are silenced or cancelled without being heard.

Transgenderism for children is unscientific and should be called child abuse in my opinion. It is based on a one-sided narrative pushed by special interests and the ever-eager media. Fortunately, some jurisdictions have begun to backtrack on blanket acceptance of transgender ideology, having woken up to its dangers and disastrous results for many. Alas, Canada has not yet seen reason in this area and presses ahead with laws and policies, school curricula and employee training, institutional pandering and media celebration, all in 'support' of anything LGBT, and especially 'trans'. Meanwhile, those of us wanting to hold onto sanity are judged, condemned and usually silence ourselves out of fear, or for lack of public places to turn to. We wonder how and when this departure from reality will end.

Israel vs. Palestine:
From a western, democratic perspective, this issue should be a slam dunk: one small country, the only open and stable democracy in the region, is surrounded by dysfunctional, backward, tyrannical  countries that want to destroy it.  Do you side with the democracy or their enemies? Founded after holocaust, Israel defends itself effectively and by necessity against attacks from three sides, and hateful diatribe from many other nations who should know better. Support for Israel should be a social justice cause, but it is not.  Instead, the left and progressives in general support Hamas and Hezbollah, recognized terrorist groups who continual threaten Israel, unwilling to negotiate in good faith, while unable to support their own people, giving them fewer human rights, unstable governments, conditions of poverty despite ongoing international aid and nearby oil wealth.

Yes, Israel is sometimes guilty of bad behaviour, including heavy retaliation for armed attacks, and building Jewish settlements on land claimed by Palestinians. But they also provide for Palestinians within their borders, allow them to live, work and vote peacefully, and even to serve in the government. Meanwhile, surrounding countries do not want the Palestinians in their lands and provide little actual support to them. (Such is my understanding from my limited exposure to Middle-East political reality.) I may be wrong in siding with Israel for the most part, but I do not understand those who side with Palestinians to the point of demonstrating on campus, denouncing Israel, or demanding that nations and corporations stop dealing with Israel. 

Okay, that's enough for now!

This, of course, is just a brief and partial collection. Any one of these topics deserves a full blog post (or even a book?) and perhaps I'll expand on a few of them later, or just add a few more briefs here. There are other subjects I could expound on, such as feminism, other LGBT aspects, additional woke causes, and a few more technical/scientific subject areas, but the above entries will have to suffice for now. They will certainly serve for many to pigeonhole me, without thinking, as a "far right monster", or something similar, but I prefer to be a 'contrarian' and a very reasonable one at that!

On many of these topics there are, of course, grey in-between positions, and perhaps I myself do not entirely hold the views outlined above. Is it also possible that you, if you've read this far and have studied these issues, may hold some of the same views yourself, at least in part? Indeed, it is my secret hope that many, perhaps even most reasonable people secretly hold some version of these same opinions; that the world has not gone completely crazy and that sanity may one day again prevail, at least on some issues.

Residential Schools Narratives

I have held off writing this for a while, unsure how the issue would play out, but also concerned about how my views would be received, including possible negative reactions. However, the subject keeps gnawing at me, so I will leap into it regardless. Please don't judge me too harshly.

By now the standard "Residential Schools" narrative is well known to Canadians. In the pre-confederation 19th century, the then British government decided to set up schools for Indian children in order to assimilate them into Canadian (mostly English) culture - "to take the Indian out of the child", as it was understood. After confederation, the government expanded the program, building more "industrial schools" to house and educate children from several reserves. Church groups signed up teachers and other staff to run the schools. Native children were taken, by force, if necessary, from their homes and families to distant schools where they had their hair cut off and clothing burned. They were given English names (or even just numbers) and school uniforms, forbidden from using their own languages, and forced to speak English, while undergoing harsh discipline as they attended and lived at the schools. The children were mistreated, undernourished, given little medical care, and prevented from returning home. Many were emotionally, physically and even sexually abused, and all were mistreated in various ways by the white adult staff, who looked down on them. Some were even beaten or starved and frozen to death, then secretly buried and never heard from again. 

In all, spread over more than a century, around 150,000 native children attended over 100 of these schools, some of which remained open into the late 20th century.  Of those children, several thousand died at the schools, and many were then buried on site in unmarked graves. Most of the children who attended these schools were emotionally traumatized and permanently bear the scars as victims of this "cultural genocide" - the stamping out of their native values, tribal history and beliefs. The government has since apologized repeatedly for the whole debacle and justifiably paid large sums to the survivors and their offspring as partial compensation for the widespread and long-term suffering that still carries over today in succeeding generations. Non-native Canadians, referred to as "settlers" - are now expected to acknowledge the widespread mistreatment and atrocities, and undergo continuing education and penance for this sad part of our national history.

Such is the story as pulled together over the past few decades and captured in the 2015 Truth and Reconciliation Commision report, and its follow-up work. This narrative has been almost universally adopted by our governments, schools, churches, service agencies, and of course, the mainstream media, who have made it their duty to refer to it in news and opinion pieces as often as possible. All Canadian "settlers" are expected to accept the narrative as part of the reconciliation work and making amends. Churches are regularly shamed for their past roles, and often held to blame for most of the problems. The narrative is now part of Canadian history taught to all school children, and officials everywhere regularly acknowledge this shameful past.

Here is a somewhat different version of the story. In the 19th century the British, and later, Canadian governments were concerned that there was no public education for native children. Tribal leaders and native parents were mostly eager to have their children educated so that they would not be left behind in the burgeoning Canadian culture. Many native reserves were too small or remote to sustain schools, so the government organized and built the residential schools in more central locations, where the children could stay during school sessions. Wanting to educate and children in the faith and give them better lives and prospects for success, church groups agreed to fill the administrative and teaching posts in these schools. Many native children attended other schools in their own communities while living at home, but most who could not were transported to the residential schools, where they lived and learned together.

The schools were largely underfunded by the government, but the often-untrained staff did their best to make do with what they had and provide good education and care. Resources were often short however, the schools were understaffed, and medical care largely unavailable. Many children arrived with infestations, diseases like tuberculosis, or other health conditions. They had to be thoroughly cleansed and given new clothing, school uniforms being the norm in those days. Some of the staff were native adults, and some non-native children attended the schools as well. As the teachers could not speak the various native languages, English was taught and used in class and group activities, although most children could speak their native tongues outside the classroom. Most of the children were also able to return home between sessions, or even on weekends. 

Unfortunately, with childhood diseases uncontrolled in those days, some children did die and when they could not be sent home to their families, had to be buried in cemeteries at or near the school, with Christian burial rites and wooden markers. Records were kept at the schools and there was communication with the parents and reserves when possible. With high student-teacher ratios, including the work of food preparation and supervising the children, activities and residences 24/7, close oversight was limited. As a result, discipline had to be strict, as it was in most other schools at the time. While there were, no doubt, cases of abuse, most of it was from older to younger students, as was typical for any boarding school of that period. 

While it was understandably difficult for small children to be taken from their culture, language and family, most of the children at the schools did well enough and received a fair education. There are records and photos of happy teacher-student relationships, pleasant group outings, neat classrooms, and even hockey teams and other special activities. Many students went on to use their newly learned skills and education to help their reserves and First Nations groups, or to enhance Canadian culture. Yes, in hindsight, the rationale for the schools was partially wrong, and mistakes were doubtless made. As in any culture, some children were emotionally damaged, and the whole program could probably have been improved in numerous ways.

The former, negative narrative was developed over decades as "survivors" stories were collected and sometimes perhaps embellished with hearsay and rumours. The TRC was founded to collect and publish the history and native experiences, to put together a case for government and church apologies and reparation payments. With compensation on the table, more stories came out and the news media started to focus on the horror stories; the tragic abuse and deaths, culminating in the hyped-up reports of "unmarked graves" at various school sites in the summer of 2021.

The reader will notice that these two stories are very different. It stretches credibility to claim that both are entirely true, but both are probably mostly true, albeit biased in very different ways. While the latter story may be somewhat sugar coated, yet to publicly present only the former narrative puts a very negative spin on the residential schools issue. The fact that this is the only story the public constantly sees and hears about skews the truth and makes true reconciliation elusive.

I am not an expert on this subject but have read enough to know that the standard narrative is not the whole truth and that it is being used beyond reason - at least from my (admittedly biased) perspective - to push for repentance, apologies and reparation payments. The full truth and true reconciliation will only occur when all involved act and speak honestly. Clearly, a more balanced picture is needed, one combining both of these stories, comparing the different perspectives, while deleting any false or badly unbalanced aspects. 

The following are some questions I'd like to see answered in getting to the full truth and then to move on from the issue, so that native and non-native Canadians can live together without this hanging over their relationships forever.

1. First, what was the alternative? Everyone involved at the time wanted native children to be educated. Even in hindsight, how else could that have happened within the limitations and available resources of that century? How else could thousands of children from several hundred tribes and reserves have been educated? Who else would be willing to staff the schools if not nuns and other dedicated Christians, working far from their homes for a pittance? Where would the money to make the schools themselves, and the children's care better have come from? Which medical professionals would have been ready to live in the schools or nearby for improved medical care? How could children have been schooled in their various mother tongues? Even if the intent was colonialist and seems racist from our current perspective, at the time the residential school system seemed the best approach to address the native education problem.

2. Overall, what was the outcome for most native children: those who attended these schools compared to those who stayed home on the reserves, with or without schooling there? Have there been any statistical comparisons of how those children subsequently fared as adults in the Canadian milieu? Less than half of native children attended the residential schools, so there should be a large control group to provide such comparisons. 

Did those on reserves learn useful skills for living in Canada? Did they suffer less sickness, abuse and death than in the schools? Comparing them as adults today, can any trends be seen in personality, mental health, and other measures of well-being? Surely some of this data must exist, but have we seen it presented in an unbiased fashion? Not all residential school reports are negative. Many children did well, learned a lot and graduated as educated youth. Many staff and teachers treated them well, within the constraints of a formal school. The whole program was not entirely wrong as implied by the narrative. (See below for various references about this.)

3. How many children actually died at the residential schools and what did they die of? Compare that with deaths back on the reserves, or even with deaths in white communities of the same areas. Recall that tuberculosis was rampant on the reserves (and many other places) along with influenza (the 2019 Spanish Flu epidemic, for example). Then there were pertussis, diphtheria, measles and various other childhood diseases, each taking its toll without vaccines or antibiotics available back then. And of course, accidents and misadventure were more common as well, with fewer safety regulations in force. Children dying was altogether too common everywhere a century or more ago. Indeed, even in settler communities, 20% of children might have died before reaching adulthood.

4. How many children's bodies have actually been found in the "unmarked graves" so often reported by the media? Not how many disturbed plots of ground there seem to be, but actual exhumed skeletal remains? As I write this, I have heard of none! There is lots of talk and speculation, but no actual diggings. Not all of the graves we actually know about may have children from the schools. Adults must have died at the schools, as well, and some of the cemeteries were also used by the local communities. Moreover, one wonders, if it is not wrong to ask, how many "unmarked graves" there are for children on the reserves? Should we take a look?

Were the graves truly unmarked, or just minimally marked and the markers lost over time? Many cemeteries across Canada have lost grave markers, and some have even been bulldozed for development!  In any case, it is likely that almost all of the children buried near residential schools died from diseases rather than any mistreatment or violence at the school. We won't know until we do forensic digging or delve through whatever records still exist.

5. What other institution, active over 120 years, that kept 150,000 children 24/7 does not have a history of abuse, as viewed from the 21st century? There has been child abuse in every arena of life, and some things we call abuse today were normal disciplinary policy or children's treatment back then. Every institution has its horror stories, from English boarding schools, cadet training camps, boy scouts, hazing of college students, etc. Was the apparent mistreatment of children in residential schools worse than that seen in those venues? Or how about the legendary stories of mistreatment by nuns in Catholic schools in the last century? Any setting having children of varying ages together with few adults around the clock is going to yield abuse, especially in the years before child abuse was widely recognized and preventive measures put in place. Yet you never hear of reparations for all children who participated in those institutions. 

6. Which other country has had no historical problems dealing with its indigenous populations? Canada did not have widespread "Indian wars" like in the USA. Many countries had true genocides (mass killings) in their past, which they generally downplay. I expect that Canada's record of treating native peoples, although not stellar by 21st century values, would look better than most colonizing powers, or even many modern countries. Yet the negative media hype about our residential schools has given Canada a black eye internationally, even with China; hardly a bastion of human rights. However bad the residential school experience may have been for some, it pales in comparison with past events in other countries: six million purposely killed and burned or dumped in truly mass graves in Germany in the early 1940's; millions killed in Soviet Russia from 1920 to 1950; tens of millions dead in Mao's long march and great leap forward; the killing fields of Cambodia; the massacre of Armenians in Turkey; the Rwandan massacre; the list goes on. And all of this came after the colonial period of mass slaughters, forced slavery, tribal conflicts, slavery, etc. - atrocities stretching back into pre-history. Even our peaceful First Nations are not without guilt: the Mohawks wiped out some of the Huron tribes and killed many a settler. No people or nation is innocent in this regard!

7. Are we unfairly judging the 19th century based on 21st century values, mores and cultural norms? Regarding disciplinary measures, nutritional standards, health care, class size, human rights, family structure, pedagogy, expectations on children, social welfare, communications, and so on, the norms in past centuries were very different from those today. It is chronological arrogance and grossly unfair to judge people, processes and decisions from a hundred years ago by today's standards! How much of the supposed mistreatment being remembered is largely a projection of today's views onto the past? What aspects of today's Canadian culture will be severely judged a hundred years from now?

8. How much of the negative reporting can be counted as objective truth? Any five-year-old taken from her family to an alien culture and people, given a scrubbing and haircut, unfamiliar clothing, a set of rules and procedures in an unknown language, with strict discipline, would surely feel emotionally traumatized, however well the school staff tried to make her happy. Such treatment would loom large in her memory and, when discussed with other children, would surely grow in scope and import. Later in life, those memories would serve well as the presumed cause for her ongoing problems in life, and would be recalled when solicited, to bolster the narrative and justify payments from the government. I'm not saying that many native children were not ill-treated, but many settler children also bear scars of childhood abuse and emotional trauma, without blaming Canada and the entire school system, or expecting compensation.

9. Does repeating and promoting the standard narrative today resolve the issue for our native peoples? Has it led to proper reconciliation? Hyping incomplete stories, sensationalizing poor treatment with rumours and embellishments to gain attention is surely not the way to deal with past issues. Terms like "genocide", "settlers", "mass graves", "survivors", "murder", "victim", etc. are not conducive to reasonable discussion, freely given empathy, and mutual efforts to assess and sort through the past and its effects on the present. The churches involved in the residential schools are unfairly demonized despite their best intentions at the time, as well as various recent apologies, compensations and public repentances, including now, a visit from the Pope. Meanwhile, several churches have been burned down or vandalized, alternative reports are ignored, and little evidence has been provided for the worst parts of the standard public narrative. This is not the way to resolve the deep-seated and complex issues about the residential schools.

One could go on asking questions, but the above is summarized as follows. The residential schools were well intended, even though in hindsight, apparently misguided, poorly done, and pushed too far. The Truth and Reconciliation Commission and the subsequent public narrative are one sided, painting an incomplete and somewhat unfair picture of the past. Many native children had good experiences, learned a lot and came out ahead. Not all were abused, damaged and scarred for life. Most of the staff did their best in difficult circumstances with what they had, based on the standards of the day. The current narrative is unhelpful in that most people can see how skewed it is and may therefore, be inclined to take it with quiet cynicism, rather than full acceptance. Without looking into these matters using hard evidence in addition to the usual verbal reports of childhood memories, we will never clarify and sort out the full truth about the residential schools.

Canadians today are surely not to blame for what happened 100 years ago, and yet, we are now trying to make amends and work with the First Nations to improve their circumstances. When he expanded the residential school program, John A. McDonald (Canada's first Prime Minister, back in 1870's) was trying to do the right thing, based on what was then known and within the resource limitations of the day. But what "the right thing" looks like is hard to sort out even now in the current melee of media hype, biased presentations, expanding grievances, shifting reserve realities, and other aspects of the issues surrounding Canada's First Nations peoples. Indeed, all recent attempts to sort out and come to agreeable terms with Canada's indigenous peoples have been mired in confusion and disagreement. No government seems to have a plan that First Nations will accept and support.

One final clarification must be made. This piece - or rant, if you prefer - is only about the residential schools issue. It is not intended to reflect my views about First Nations in Canada or indigenous peoples in general. There is no doubt that when Europeans arrived in what is now Canada, the result was devastation for the indigenous population, primarily through diseases unknowingly transmitted, but also through mistreatment and abuse. Then there were the treaties which carved more and more of the native lands away, and which were often not implemented by the settlers. Add in the cheating and swindles that went on, and the racist presumption of white cultural superiority, as well as the technological disadvantages, and the native peoples of Canada have had very poor treatment over the centuries. 

Fortunately, however, this has largely shifted in recent decades as First Nations have come into their own, rebuilding much of their varied cultures, and now flexing their political power to assert their rights and wishes. But many cultural scars and serious problems on and off the reserves remain unresolved. The history of the residential school system probably contributed to both sides of this journey but adopting only the negative narrative is not fair and will probably not help the native peoples in the long run. Yes, Canada like many countries, has a problem dealing with its indigenous peoples. There are valid historical and ongoing grievances that need to be addressed, and no comprehensive solution is in sight. But there will not be a just and settled reconciliation until the full truth is available and all sides behave fairly and honestly with each other. 

This piece reflects my current opinion, based on incomplete readings and partial data, so I doubtless have some errors and am likely in need of correction in some details. My writings are not entirely original, of course. I have been greatly educated and aided by various pieces written by brave souls questioning the standard media narrative, mostly through smaller publications. Here are some of the ones I have collected for further reading and edification:

Some Green Energy Reality

 There is a big push everywhere to reduce our use of fossil fuels, replacing them with renewable energy sources, such as solar or wind power.  This pressure, of course, is driven by climate change ideology and related concerns about a warming planet.  The most eager folk hope that we will be "carbon neutral" by 2030, urged on by the United Nations and recent IPCC edicts and warnings.  Regardless of how important you think the issue, the push for "clean energy" will doubtless continue unabated for a long time.  Under the guise of "net zero", to stop emitting carbon dioxide from burning coal, oil and gas, many governments and industries are slowly installing more wind and solar power.  Those both produce electric power, so there is also a push to switch vehicles and various industrial processes over to electricity. 

The often unrecognized problem with wind and solar energy is that they are intermittent; the sun doesn't shine at night, the wind often does not blow, and clouds come by at random intervals.  To make up for the times when renewable energy is unavailable, requires some form of backup energy storage medium; a system that can easily convert from electric grid power and back again in a controlled and practical fashion.  Replacing all other electric power sources with wind and solar would require absurd levels of backup storage for many days, or even weeks -- to get us through a Canadian winter, for example. 

To explain this better, consider a modest city of one million people, which typically requires 2 gigawatt (GW) of electric power on average, with likely variations between 1 and 3 GW. If all of that must come from wind and solar, the city would need at least 6 GW of solar and wind generating capacity to get an average around 2 GW, and a minimum of 30 GWh (gigawatt-hours) of backup storage just to make it through one windless night.  That is equivalent to more than 500,000 electric car battery packs.  Even then there would be a high probability of frequent outages.  Maintaining a truly reliable grid solely with wind and solar power would increase these numbers further.

Of course by 2030 wind and solar will NOT provide all our electricity no matter how loud the alarmists shout and the green people dream.  Nuclear energy will still be around, providing constant base generation (24/7), and with new technology, nuclear may be pressed into moderate, long-term growth, if governments can deflect or appease the anti-nuclear crowd.  However, nuclear power cannot easily be dispatched; that is turned up and down at a moment's notice to match the instantaneous demand in the power grid.  Nuclear takes days to start up or shut down properly and works best operating at a constant output power - hence the base supply.

Then there is hydroelectric power, which is somewhat or partially dispatchable, providing some limited "energy storage" by way of water reservoirs - not nearly enough, of course, to replace reliable and fully dispatchable fossil fuel plants, but some.  And hydro-power cannot be expanded much since all the good sites are already in use.  In addition to solar and wind, there may be other renewable energy sources that can run on stored energy; e.g. fuel cells and hydrogen, although I personally would not invest in that (see more below). 

Dispatchable loads may also come into play: allowing your air conditioning or electric vehicle recharging to happen at the whim of the grid controllers, so as to shift their loads into times when power is abundant - all for a modest reduction in your cost per kWh.  Mind you, industry and commercial enterprises have so far not been keen to accept brownouts in return for reduced rates, but some degree of "load shifting" should be palatable to most people if done well.  In addition, there will continue to be modest improvements in process efficiencies: better insulated homes, tightened up industries, reducing energy and heat waste a bit. Together these may reduce or flatten peak loads through the day.

These changes, together with the inevitable residual natural-gas generating stations (which are very dispatchable), other traditional generating plants, and possibly newer power sources such as biogas, ethanol and biodiesel, would greatly reduce the amount of energy storage required as we move toward a more sustainable future.  Nevertheless, huge investments in energy storage for electric power will have to be made if we want to continue adding wind and solar capacity while keeping our power grids reliable, as every consumer expects. 

The obvious choice for electric energy storage is batteries.  When grid power is plentiful, AC power is rectified to DC and used to charge electro-chemical battery cells.  When extra power is needed, the batteries discharge through inverter circuits to feed AC power back into the grid.  The current front-runner in this regard is rechargeable lithium batteries of varying internal chemistries and constructions.  Encouraged by the growing EV market, lithium cells are slowly getting better and less expensive.  They have a high round-trip efficiency (kWh returned to the grid vs. kWh required to recharge them) around 80%, are rapidly dispatchable in either mode, and have a decent usable life.  Potential problems with limited materials resources can probably be worked around over time, and the cells can be recycled. 

Large (gigawatt-hour - GWh) battery storage plants are currently in planning or under construction. They are intended to shift loads by a few hours at most, not by days or weeks, and even so, they will be expensive.  Many such plants would be needed (terawatt storage!) to do away with fossil fuel generation altogether, so that is unlikely to occur by 2030. 

There are other, often-hyped energy storage media possibilities, such as pumped water, compressed air, hydrogen, thermal storage, flywheels, artificial fuels, raised heavy weights, and so on.  However, they all suffer from either low round-trip efficiency (e.g. hydrogen, air, thermal), capacity and scalability issues (pumped water, raised weights), or large capital costs (most of these).  These technologies will find small, niche markets, but are unlikely to provide grid-wide backup power at the required level.

Combined with their low operating factor (less than 40% of the time storing and less than 40% releasing stored energy) means that any stored power supply is expensive on a dollars per delivered kWh basis (both capital and operating) compared to raw solar/wind or most traditional energy sources.  As far as I am aware, no other energy storage technology can match batteries for high efficiency, flexibility, and response time.  Yet even batteries can provide backup power at less than 33% utility (80% efficiency, combined with < 40% discharge time).  Thus, if a battery plant and nuclear plant cost the same on a per kilowatt rating basis (I doubt if they do, but just suppose), then the long-term cost per delivered kWh of the battery plant would be at least three times that of the nuclear power plant, depending on other assumptions and variables.

Ultimately, of course, reality will have its way.  Yes, we will get additional solar and wind energy, some large (but limited) battery storage plants, some percentage dispatchable loads, more nuclear, and slivers of additional hydro and other sources, but we will also keep many clean gas-fired turbine generators; and probably more than a few other carbon-based power plants will continue operating after 2030. Perhaps by then the "climate change" demands will become sufficiently subject to reason that the push for "net zero" will fade, diminish, or quite reasonably be pushed out a few decades more.

In the end, reality always wins, and we will continue to have a mix of energy sources and storage media going into the future.

The Bad Design Argument

 In the study of the history of life on the Earth, there are two and only two reasonable explanations. Either a mind - AKA intelligent agent - played some role in directing evolution over the past 4 billion or so years, as claimed by Intelligent Design theory (ID), or else there was no intelligence involved and life evolved by random chance, natural selection, and other unguided, natural processes, as held by modern Darwinists. Any proposed alternative must be one or other of these, and of course, any mix of these two is still ID at some level. 

At some point in debates about Intelligent Design, you will likely hear comments about how badly the human body (eye, hand, reproduction, etc.) or some other animal is designed. A brief statement will usually follow to the effect that, "God would have made a better design if he was the designer, therefore there is no designer and evolution is true." This presumptive "logic" can come in different guises, usually with along with some supposed examples of "bad design". However, for a variety of reasons, which I will explore, this is a bad argument.

The "bad design" argument is usually brought up by atheists or materialists who do not believe in God. Yet here they pretend to know what God should have done, based on their own ignorance of the design and of any relevant theology. The hubris and irony here are thick! They assume a series of "bad designs" and suggest that those must have come about by an unguided, and hence imperfect, process; i.e. Darwinian evolution. Note however, that even if their examples of poor designs in life were true, even poor designs require a designer! An incompetent designer is still a designer and the "no designer" conclusion does not automatically follow from the "poor design" judgement. ID theory does not require that the designer be the God of the Bible, even if he is the obvious candidate.

Nevertheless, such summary judgements about "bad design" are usually also wrong in the sense that a detailed study often shows that the particular feature in question is in fact a good design for reasons not appreciated by the accuser. One example is the supposedly "reverse wired" human eyeball, where the optic nerves are in front of the retina, thereby blocking some of the light. The human appendix is another example offered as an unnecessary evolutionary left over serving no purpose. These and many other "bad design" claims have been refuted. See this article for some examples.

This raises another point; the person making the "{bad design" call is usually just passing along some meme that he has read or heard and has no real understanding of the biology or physiology in question, much less the alternative explanations. Thus it is often merely an argument from ignorance. A wiser approach would be to learn more about the feature or design in question before passing judgement on it.

In general and especially in engineering design practice, it is impossible to judge someone's design without knowing the design specifications and constraints behind it: the purpose, capabilities, cost, schedule, regulations, available materials, limitations, and so on imposed on the design process and resulting product. As an erstwhile systems design engineer, I can state unequivocally that there is no such thing as a "perfect design". All designs are an attempt to optimize some aspect of the designed item within the constraints of the project. All designs can be "improved" by additional effort and cost, but once a design is deemed "good enough" it is usually released to meet the schedule. 

All designs also involve trade-offs among various parameters and constraints. Without knowing all of those, it is unwise to judge the resulting product or process. Of course, we all complain about products that don't work properly, or that break because they were cheaply made. But those are human-designed products, none of which come close to the complexity and integrity of even the simplest living creature. Humility is therefore a better starting place in judging the fitness and merit of any human design, and even more so for designs found in nature. Indeed, more and more these days engineers are looking at design in nature for ideas on how to improve their own products.

Another point is that no designed thing operates in a vacuum, apart from the rest of the world. Everything is part of some larger system which it must interact with and perform within. Every living thing is part of a broader ecosystem where it plays different roles, and those interactions raise additional constraints that need to be taken into account from the design perspective. For instance, in principle, herbivores could be made faster or more powerful than the carnivores preying on them, but then the carnivores would die out, unbalancing the ecosystem. From the herbivore perspective, they might feel they are poorly designed, but a higher level viewpoint shows that ecological balance is more important.

Since the "bad design" argument is usually an attack on Theism, some additional things may be said about their ultimate target: God and (usually) Christianity. Note that God never claimed that creation was "perfect", he only judged it as "very good". Perfection apart from God is not possible. Moreover, once creation was completed, things started to go down hill quickly, initially due to the Fall and the entrance of sin into the world, which messes with everything (see Genesis 3). 

Moreover, due to entropy, all of the created world, including humans, began to break down and collect imperfections. As with any designed item, wear and tear, environmental effects, usage past its best-before date, abuse, and other realities cause even well-designed things to stop working, break down, or work poorly. Some seeming design problems in humans can be traced to errors finding their way into our genome. For example, humans cannot make Vitamin-C due to a genetic defect, and of course, many diseases can be traced to errors that have crept into our genome over time.

The next time you entertain (or are tempted to make) this "bad design", anti-ID argument, think first and ask yourself, "What have I designed so that I can judge a complex system like the human body?", or "Have I examined the design constraints and purposes for this particular item being judged?" That should slow down the negativity and allow the debate or discussion to proceed in a more useful and meaningful direction. By all means, keep up the discussion, but please base it on defensible evidence and reasonable arguments.
