Natural History: Some Even More Random Rambling

Sometimes you have a new thought, an idea, or eureka moment, but it’s not gutsy enough to expand into a reasonable length article or essay. So, here’s a potpourri of thoughts too good not to record, but with not enough meat available to flesh out. 

oooooOOOOOooooo

* We’ve all read and heard about how we consume way more salt than is necessary and that too much salt can cause high blood pressure and heart attacks and associated nasty conditions. What is never mentioned in all these health warnings about salt is the feedback mechanism that restores the proper balance. It’s akin to how many bars will put out free salted peanuts or salted chips for the customers. It’s not out of the pure kindness of the bartender. If you take in a lot of salt you get, surprise, thirsty. And so the bar makes up for the ‘free’ peanuts and chips by selling more drinks to quench the thirst you build up by eating all that ‘free’ salty stuff. In other words, if you over indulge in the salt, you’ll drink more fluids because you get extra thirsty, and the additional liquids will, when filtered through the kidneys, take the unnecessary salt with it (salty urine) and the proper balance is restored. So, if we consume way more salt than is necessary, we probably drink way more fluids as well. 

oooooOOOOOooooo

* I think most of us would agree that a reasonable definition of free will is the ability to voluntarily and consciously choose between two (or more) courses of action. You make a decision by your own free will that’s generated by your internal conscious self with no external influences, like someone, even Mother Nature, holding a gun to your head! However…

What if you view an optical illusion, an apparent reality of which there are numerous classic examples available? Initially you have two choices. You can convince yourself that what you are seeing is indeed reality (wrong choice) or you can convince yourself that what you’re seeing is not reality (right choice). But that’s mission impossible.

You know – you are consciously aware – that what you are looking at is an illusion and not reality. Can you now, of your own free will, take that course of action that will actually convince yourself that what you are looking at is an illusion and not reality? You know it’s an illusion, but can you convince yourself of that fact? Try as you might, no matter what, you will still see that apparent reality – the illusion – even though you know it’s just an illusion. Your brain is fooled and your mind can’t do a damn thing about it. Your free will cannot free yourself from seeing the illusion. You cannot negate that illusionary effect of your own free will even though you know it is not reality.

Now some optical illusions give you the apparent free will to view the illusion as this thing or that thing (like the classic two faces or one vase), but you can’t sustain that. You will shift perspective between the two illusionary options quite against what your own free will dictates. Further, you don’t have the free will third option of seeing neither of the two illusionary options.  

In a somewhat similar vein, watching one of the season three episodes of “Through the Wormhole”, part of that episode, exploring the subconscious, showed the experiment of a test subject who was fitted with a pair of camera-glasses that showed him an image of a test dummy dressed the same as the test subject. The test subject was fully aware of this. The test subject was then conditioned by being stroked with a rod while at the same time viewing the test dummy being stroked. Then, the test dummy was suddenly violently assaulted, and of course the test subject reacted as if he were being assaulted and not the dummy. Even when the test subject was told that the dummy was going to be assaulted, he was aware of this in his conscious mind, he still couldn’t help himself via his subconscious reacting as if he were being assaulted instead of the dummy. 

In short, your conscious mind cannot override or overturn your subconscious, free will be damned.

oooooOOOOOooooo

* Despite the very popular but self-promotional conception, human beings are the least rational species on this planet. Any other animal that acts irrationally, say via a genetic defect or disease or the equivalent of dementia, is a dead animal. I have yet to witness any animal acting in any way, shape, manner or form that wasn’t rational for either its own survival or the survival of its genes, its community or its kind. I most certainly cannot say the same about the human species.

oooooOOOOOooooo

* Here’s a wicked thought experiment. Create two clones of yourself. Raise them to maturity. Then, remove their brains and toss them away (this is just a thought experiment and so morals and ethics can be bypassed). Now have your brain removed (and toss your body away). Have one hemisphere transplanted into one clone; the other hemisphere transplanted into the second clone. While the two hemispheres of your brain have slightly different emphasis in terms of functionality, you can function as a reasonable whole with just one hemisphere. Now the question arises, will you be self-aware in two bodies at the exact same time? You could accomplish twice as much and be totally aware of the totality!

oooooOOOOOooooo

* Humans and cycles go hand in glove. Though most are artificial constructions and therefore rather phoney, cycles are important to humans and human society. The Day-Night cycle is of the most prime importance, and it is a natural cycle. Humans put a lot of stock in the seven day week cycle, which is an artificial construct, and to a lesser extent the month (also a phoney cycle even if ever so loosely based on the lunar cycle). The year is a natural cycle (in terms of the seasons) and probably of greatest significance next to the day and week cycles. Decades and centuries rank fairly low in importance and are artificial constructs in any event. The millennia are only important when the calendar changes over from say 1999 to 2000 (though the new millennia actually began in 2001) and 1000 year cycles lie outside of the human lifespan in any event. And that should be pretty much it – except for some ancient societies who had cycles of apparent importance so long that predated the very existence of those societies (and concluded well after those societies went extinct), like the Mayan long count (recall that famous doomsday date of 21 December 2012). Other societies measure ongoing cycles of creation-destruction in such lengthy periods that they really have no imminent impact on the societies propagating them. When societies have cycles of significance that are of no immediate significance, then you have an anomaly and you have got to wonder where hence gave that particular cyclic concept.

oooooOOOOOooooo

* Try as I might, I could never teach my cats the barest and most basic rudiments of algebra or even those boneheaded elementary mathematics of arithmetic that elementary schoolkids master. I could never get my cats to understand and appreciate the ancient Egyptian cat cults and goddesses. Even the concept of biological evolution – the how and why cats evolved into cats and the ancestry of my cats would be so much triple-Dutch to them. Their wetware, neurochemistry, etc. just isn’t up to this. Sunshine gives them warmth – that they understand but not how the sun shines.

Now, the upshot of that is, despite the human arrogance that our minds can comprehend everything part and parcel of life, the Universe and everything, perhaps we just can’t through absolutely no fault of our own. Maybe human brains, in the here and now, are not capable of figuring all things out, like the meaning of quantum physics, and the theory of everything (TOE) which is basically a theory of quantum gravity and coming to terms with what exactly is dark matter and dark energy and answering all those other questions that have gone without resolution for thousands of years.  

oooooOOOOOooooo

* You probably think of yourself as one singular organism. The expression “me, myself and I” are all singular. Yet, you know perfectly well that you are really a colony of billions of organisms (cells) working in more often as not the case in total harmony. Yet, as things turn out, you play host to billions and billions more microbes. Nine out of ten of the microbes that make you up aren’t really a part of you at all, like say those bacteria that survive and thrive in your mouth. So, are you an organism, a colony of organisms or an environment for organisms? I’m quite astounded to learn that 90% of me isn’t me! So perhaps our real purpose in life is to serve as hosts for the greater multitudes. The needs of the many [microbes] outweigh the needs of the one [Human].

oooooOOOOOooooo

* In the simulated universe scenario I (and many others) have suggested we exist inside a computer as a software program or subroutine within a larger software program. The un-stated assumption is that the Supreme Programmer was of flesh-and-blood (terrestrial or extraterrestrial). But why make that assumption? Why not suggest that the Supreme Programmer was/is an Artificial Intelligence in its own right just being creative. Silicon –and-steel (artificial) intelligence is a logical evolutionary successor to flesh-and-blood (natural) intelligence and is likely to not only evolve far more rapidly (Moore’s Law) than human evolution ever did but have an overall longevity vastly in extent of ours.

Human Reality Revisited: Part Two

In these life and times of your day-to-day activities, going about your business in this four dimensional space-time you find yourself stuck in, I doubt whether you question that what you experience is anything but the truth, the whole truth and nothing but the truth. What you see is what you get, and what you get is really real reality, absolute nuts-and-bolts no question about it reality. If that’s what you think, think again.

Continued from yesterday’s blog…

REALITY OUTSIDE OF THE STRIKE ZONE: THE NEBULOUS OTHER

What if someone or something else is pulling your chain? So far I’ve gone on the scenario that there’s a really real reality out there for you to experience and absorb. You are pulling your own chain; dancing to your own tune. Now what if some significant other is calling the shots?

You are a natural entity with wetware rooted in carbon chemistry

- A bit outside the scope of normality or what passes for normality, there are whole textbooks full of case studies of brains that haven’t been hardwired up quite correctly and so you’ve cases of people hearing colors or mistaking their wife for a hat or who have multiple personalities or seriously believe they are Alexander the Great, Jesus, or say President Kennedy.

- Although it doesn’t necessarily follow, there are those who believe that those who see ghosts or aliens or angels or the Loch Ness Monster are fantasy prone; just internally generated visions that’s all in the mind. Can shamans, mystics, gurus, and related really visit an otherworld of alternate realities, or are they too just fantasy prone, with perhaps some help from smoking the good stuff. Of course if they are experiencing such things, well that in turn might be evidence for alternative realities.

- And don’t we as adults construct an entire fantasy world for children – Santa Claus, the Tooth Fairy, the Easter Bunny, even the Bogyman who’ll, we say, do nasty things to naughty kids. Don’t children on their own construct fantasy worlds they live in along with invisible playmates? I wonder if there’s anything really different in principle between children believing in their invisible friends and adults putting their faith in invisible deities.  

- Adults too immerse themselves in fantasy worlds from putting on virtual reality helmets to boldly go (the 20th Century version of the Star Trek holodeck), to actually dressing up in Star Trek or Star Wars outfits as various characters from those (and other) fictional worlds, to participating in all sorts of role-playing scenarios. Though one would hope that when doing dress-up for masquerade balls and attending fantasy conventions, the adults would be aware that they are doing make-believe. You’d hope that though some fans (fanatics?) can get really carried away to extremes, like naming their kids after their favorite fantasy character, collecting thousands of items of memorabilia, even say modeling and outfitting their home to resemble the interior sets of say the Starship Enterprise. It’s been done! Though I suspect this must be a modern phenomenon. I don’t recall ever hearing about people in the 17th, 18th or 19th Centuries playing at King Arthur, holding mock battles and jousting contests, though maybe I’m wrong on that. It’s certainly common today for hundreds to play dress-up and reenact Civil War engagements, and there’s many a wannabe cowboy out there in suburbia. 

- Your natural brain-in-a-vat scenario might be where some ‘mad’ scientist has cultured some brain cells in a petri dish and eventually grown a full-sized brain-in-a-vat which is kept stimulated 24/7 with electrical impulses – your reality. Or, perhaps your body has aged and kicked-the-bucket but your brain – still alive and ‘kicking’ – has been removed and kept alive but in ‘storage’, but still requiring stimulation, pending a suitable transplant into another body whose brain has died.

- Your natural brain is being manipulated scenario. Say you’re a patient in a hospital in a coma, or undergoing a neurosurgical operation and your brain is being stimulated in an effort to determine what’s what. Perhaps that stimulation is what you take, while in your coma, or under-the-knife, to be your reality – but all you sense and remember is really being induced. There might even be a time dilation effect. Presumably you could electrically stimulate the brain such that the brain would experience or remember years worth of experiences but the applied stimulus is just taking a few minutes. 

- You’re dreaming. You are really a bug-eyed-monster from the planet Zork; or a pussy cat; or even a human; but you’re asleep and dreaming this alternative lifestyle which in this dream state you are interpreting as your actual reality. Until you wake up, your dream IS your reality.

- One or many? You could philosophically argue that the sum total of life, the universe and everything is illusionary and just the product of Your Mind. Life, the universe and everything (all else but your mind) is just Your Mind playing games, a created illusion or construction to keep Your Mind from being bored. Or, you see someone in the shops and you conclude that as you see them, they see you, and both of you have a perception that there’s a really real reality and both of you are a part of that. That’s the common sense worldview, but the universe doesn’t always play by common sense principles. Of course it’s possible that the both of you are all part of a larger mass hallucination; that you aren’t The Mind, but rather one of the creations of The Mind of someone else. 

There is no way you could distinguish any of the above realities from your perception of what’s really real.

WILD PITCH, ERROR ON THE THROW

You are an artificial entity

Needless to relate, there has been a massive amount of theoretical and practical research dedicated towards the goal of creating an artificial mind, a silicon chip mind or a mind made out of silicon chips, machine intelligence, otherwise more commonly known as artificial intelligence. The reasons are manifold, from just the academic pursuit of seeing if it can be done for the sake of seeing if it can be done, to practical applications like designing robots that can assist in making the lives of the handicapped or elderly or the lonely more bearable or beating the pants off of some egomaniac chess champion, to putting artificial intelligence to the same sorts of creative use that wetware intelligence is put to. Perhaps an artificial intelligence can put two and two together and come up with a Theory of Everything, the Holy Grail of physics. Artificial intelligence can also boldly go where wetware intelligence cannot since silicon chips are a bit more durable under extreme environmental conditions than flesh-and-blood.

Put another way, if Mother Nature can evolve flesh-and-blood intelligence, then that flesh-and-blood intelligence can create and evolve machine intelligence (and ultimately that machine intelligence can further evolve and advance the capabilities of machine intelligence). The basic reason is that there is no difference in principle between a squishy neural network, and a silicon chip network. It all operates on electrical connections, complex connects it is true, but just wiring. Now, the question arises, is your mind a squishy neural network or a silicon chip network? There’s also a third possibility. Your mind isn’t physical at all – squishy or silicon – but mathematical. Your mind is just computer code. 

- Your artificial ‘brain’-in-a-vat scenario might revolve around the idea that you, or rather your mind, is just a processing machine sitting on a bench top or on a shelf, maybe as a prototype, being fed data (that’s your reality) to see if your silicon chips are able to ‘think’ outside the box relative to your mind just being a sophisticated adding machine.

- Your artificial ‘brain’ is manipulated (programmed) scenario might be akin to you being a fully functional robotic android though programmed not to know in order to better integrate into the society that created you. If you cut yourself and bleed and feel pain, that’s just a programmed illusion. When you ‘die’ (your programmed use-by date) you’re recycled/reassembled – a form of reincarnation. Most of your memories are false ones programmed into you, so you believe you had a childhood for example.

- Finally, you are neither flesh-and-blood nor silicon chips. You’re just bits and bytes inside a computer. You’re a piece of software. You’re a simulated being just existing in virtual reality, created by others; manipulated by others without any awareness of this on your part.

Human Reality Revisited: Part One

You are an electromechanical device or machine, even if it’s the product of biological evolution. You certainly operate on electricity (converted from the chemical energy in your foods); you’re certainly mechanical. Those bones, joints, muscles; your movements, are certainly mechanical in nature and biomechanical engineering is certainly an active academic pursuit, especially for athletes and those with skeletal-muscular abnormalities. 

Part of that electromechanical you is your brain – more electrical than mechanical, though engineered never-the-less. Your brain houses a very up close and personal part of you – your mind. Your mind is the key to your reality which will not be the same as anyone else’s reality and in fact your reality maybe totally unreal.

The only thing you know that is really real is your mind. Everything else could be an illusion to a greater or lesser degree. Even your mind could be an artificial construction rather than a natural one and you would be none the wiser, but at least an artificial mind would still be a really real mind to you.

Your mind is the gateway to your perceptions of reality. If you have no mind (like before your conception) you have no perception of reality.

REALITY INSIDE THE STRIKE ZONE (EVEN IF NOT RIGHT DOWN THE MIDDLE OF THE PLATE)

Your reality is twofold. There’s your here-and-now reality, reality as perceived by your five senses and channeled into your wetware; there’s your there-and-then reality, reality stored as your memory inside your wetware. 

In either case, your reality is all in your mind. Your brain chemistry; your neural network wiring are where you’re here-and-now and there-and-then reality lie.

But is that reality accurate? Would your reality match someone else’s version of the exact same events? No!

BRAIN CHEMISTRY

Your brain chemistry is never the exact same moment to moment. Ditto for every other odd bod and sod on the planet.

What determines your brain chemistry? Your age; genetic makeup and background heritage; foods and beverages; sleep patterns; what drugs and/or medicines you use; pollutants in your immediate environment; disease and/or injury to the brain or nervous system; even outside manipulation, say electrode stimulation by a neuroscientist.

Your brain chemistry isn’t the same as anybody else’s. If everybody’s brain chemistry were the same, if everyone were hardwired up the same (neural networks), then each and every one of us would like and dislike the exact same things equally. Each election would be a 100% landslide for all votes would go to one candidate. Even the opposing candidate would vote for their opponent, which is all nonsense as the two candidates (in fact all candidates) would have identical worldviews/policies. There would be no such thing as ‘different strokes for different folks’ and as such the world would be in one hell of a mess.

FIVE SENSES

When it comes to your five senses, your mind doesn’t receive the original stimulus or stimuli, only a crude copy that’s been translated into another language – one that your mind can interpret and come to terms with.

Your mind didn’t receive that photon of light – just an electrical signal describing the information that photon carried.

Your mind didn’t receive that sound wave – just an electrical signal describing the information that sound wave carried.

Your mind didn’t receive that molecule of food odor or taste – just an electrical signal describing the odor or taste information that molecule carried.

Your mind didn’t receive that cat scratch – just an electrical signal describing the sensation of receiving a cat scratch elsewhere.

Everything ‘real’ in the here-and-now is the sum product of the feed via electrical signals into your mind via your five senses. But the ‘real’ in your mind is a crude copy of the ‘real’ outside your mind as input gets translated in the process and any translation is never as good as the original.

Another facet to that is that your five senses can be tricked into perceiving illusions. You’ve experienced optical illusions. A common one is the perception that the Sun goes around the Earth. We still say that the Sun rises and the Sun sets as if the Sun were moving and not the Earth rotating. You’re also probably familiar with the Moon Illusion, whereby the Full Moon at the horizon appears much larger than when higher up in the sky, but it is not. Your perceived reality and real reality aren’t the same. There’s also taste and smell illusions that can be perpetrated. There are illusions with touch and no doubt audio illusions as well. Mankind’s technology helps confuse the picture too. A hologram looks 3-D and solid but isn’t. The mind, via the senses, can be fooled into accepting six (or more) impossible things even before you’ve sat down to breakfast!

You’d be well aware that witnesses in courtroom cases will have their ability to translate what they experienced via their five senses into reliable data that can be recalled into question when the guilt or innocence of the accused is at stake. You’d probably be aware that there are seemingly millions of psychology studies that prove again and again that eyewitness testimony isn’t worth squat and can be easily manipulated via the power of suggestion.

Using independent instrumentation to verify reality like a thermometer or Geiger counter isn’t any better as their readings are meaningless until you use your five senses to read the readings resulting in the same translation issues and thus you’re back to square one.

Even if you have absolutely perfect sensory apparatus, your reality will be relative, not absolute, to someone else’s reality as Einstein so aptly demonstrated. Without going into a longwinded example, just accept that you may see Event A happen before Event B. Someone else in a different frame of reference sees Event B happen before Event A. Yet another person sees Event A and Event B occur simultaneously. That’s why it’s Einstein’s Theory of General and Special Relativity, and not Einstein’s Theory of General and Special Absolutes. 

MEMORY

Your Reality: Strike One: Your brain chemistry isn’t reliable or consistent.

Your Reality: Strike Two: Your five senses that input to mind isn’t reliable.

Your Reality: Strike Three: Your memory is definitely not reliable. Memory is not infallible as those courtroom dramas often highlight.

So, if 100 people experience an event, and have to recall that event say ten years later, how many versions of really real reality are you going to get? What odds that even one of these recollections will be 100% spot on?  What odds that none reflect that really real reality (RRR) of that event (assuming such a concept as RRR in the first place of course)?

To be continued…
