Causes, Facts, and Heroin

The lecturer moved his laser-pointer quickly over the loop of neural circuitry. He explained the role of Mu receptors in activating the circuit, which sent a signal round and round and came out as the behavior pattern we call addiction. It was all very neat.

It was so neat the he could have simplified his diagram by replacing the pretty brain graphic with a switch. Off would be synonymous with no addictive behavior. On would equal addictive behavior. If you took the theory, “Addiction = Brain Circuitry” at face value, anything that flips the switch would cause addiction. Yet we know that that situation does not obtain. Heroin flips the switch, but not everyone who takes heroin manifests addictive behavior.

For the advocate of “Addiction = Brain Circuitry”, there are two ways out of this dilemma. First, he can posit a multiplicity of switches. In other words, he can claim that there is an intervening network of necessary, but not sufficient, switches on either side of the Big Switch, mediating the input and output of the addiction circuit. But then in principle, all those switches could also be replaced with a single switch, and you are right back where you started. No limited set of if/then statements will be completely determinative.

The second way out of the non-correspondence dilemma is to simply abandon a complete and transparent explanation, in favor of reliable facts. Neurons are necessary to behaviors, and we know that because, if we zap certain neurons, we can reliably alter corresponding behaviors. That doesn’t exactly explain the behavior, but it lets us move on to knowledge of neural circuits and the experiences which correspond with changing the configurations of those circuits.

One might denigrate the second solution as an abandonment of truth-seeking. Perhaps, but that is not so bad, on a proper notion of truth. In solution #2, you get a theory, which is a set of reliable facts. To get to the truth what you need is an explanatory reduction. In other words, all the switches and their positions for a specific moment of behavior, across the cosmic board. Such an array is purely didactic. It refers to no knowledge, for it cannot reliably correspond with anything. You may think you know something about it, but you don’t – not until you begin to formulate a theory regarding it.

Johnnie shoots a dose of heroin because he has inherited a susceptible set of receptors, because he contains the dendritic representations of certain permissive life-lessons, because he lacks certain inhibitory representations, because he lives in a society which has heroin, because he anticipates certain effects from heroin injections. And on, and on, and on…

At the end of such an exposition (if there even is an end) what we have is just a snap-shot which we have pre-labeled, “Johnnie’s Addiction”. To make any sense of it – to know anything at all about it – we must delve in to the insufficient necessities, and be satisfied with their mere reliability. When we give Johnnie a medicine for his Addiction, we should expect that it will, to some extent, extinguish the behavior. We should expect that if we take away his heroin, his behavior will, to some extent, change. And in fact, our theory does correspond with the facts which it predicts, and upon which rests.

Like the addiction lecturer, we all frequently feel dissatisfied with reliability. We would like some non-provisional knowledge. Give us some truth, please. Aspiring to truth gets us nowhere, though. Truth is too hefty. To riff on Gettier’s classic thought experiment, Smith has the truth when he observes that a person with 10 coins in his pocket will get the job, once Smith sees that a person with 10 coins in his pocket gets the job. Yet he has no knowledge thereby. He cannot be (provisionally) right or wrong in such a statement, any more than a snapshot can be right or wrong (though our subsequent interpretations – theories – of the snapshot may be).

If Smith says, at his next interview, that the person with 10 coins in his pocket will get the job, and he takes care to put 10 coins in his own pocket in hopes of getting the job, then he may know something. He is making a knowledge claim regarding his experience with coins and interviews, and his claim may or may not correspond with his theory’s fact-conditions. Reliability is what he will get, and he will be happy with it, or not, as will we all.

Knock Out Mouse Revolution

mighty-mouse-cartoon-clipart-16

Standing in the New Orleans convention center felt a little eerie. The interior was clean and neat. It looked like an airport. Still, I could not help but recall images of Katrina, when the huge edifice had become a beacon of false hope, luring the populace through its doors with the promise of aid, only to leave those who entered trapped like rats.

We had come to a conference to learn about endocrinology, which I had not considered too creepy before. I was wrong.

The proceedings began innocently. Hundreds of physician scientists, and I, filed quietly into a giant auditorium. I want to make clear my lack of qualifications relative to the rest of the group. I am no scientist, and barely a physician. I would much rather read philosophy books and climb around on crumbly sandstone towers than pipette solutions into a gel matrix.

But my job is mostly about helping people protect themselves from diabetes. Plus my wife had a poster to present. So, there I was, attending as an imposter.

The keynote speaker got a prolonged introduction. He deserved it. He was an important person with important research credentials. It was the kind of introduction where a name is never mentioned, for dramatic effect, and because everybody already knows exactly who the subject is. It is a an effective strategy for generating anticipation in the majority who are already quite familiar with the speaker, as well as in those who have never heard of him. It works for everyone, except my wife. She is honest to a fault, and that means that she is a real subject-object-verb kind of person. When presented with a dramatic, obscure speech, her attention lapses. As the speaker walked onstage to the sound of his name, she asked me who this Francis Collins person was.

After a long moment’s reflection, I told her that Francis Collins was a bad philosopher. She seemed to accept my summary, because she promptly settled back in her theater chair to nap through the rest of the lecture. I could not sleep, though I was feeling a little jet lag as well. The lecture was fascinating. Dr. Collins had been right in the middle of genetic research since the beginning of the human genome project, and he took the audience on a trip through the whole endeavor, right up to the current moment: the Big Data revolution.

The Big Data revolution referred to the use of advanced mathematical and computing techniques to sort through scads of data for druggable targets in endocrine diseases. The special techniques had become necessary because the database had exploded. Dr. Collins and his compatriots had deciphered the genomic book of life, but when they sat down to read it, they discovered that they needed a lamp, reading glasses, bookmarks, and indeed, the semantics of the language. The genes turned out to be active in the context of all sorts of transcription factors, promotors, coactivators, corepressors, etc. There was layer upon layer of conditionals which gave meaning to the genetics.

The source of the Big Data revelation was the knockout mouse. The knockout mouse and its cousins, the knockin mouse and the humanized mouse, were what happened when researchers turned to their traditional test subjects with gene manipulation techniques learned in dissecting the genome. By studying mice with selectively induced genetic defects, the researchers had produced the dense pile of data on gene regulation which advanced computing methods might sort out for us.

By the end of the keynote address, I had mouse fever. I wanted to hear all about the things which these creatures could do, and it turned out that I had come to the right place. Over the next few days, I would hear about mutant mice who could run on a treadmill off the couch like they had trained for months. Mice who developed diabetes. Mice who could turn on their brown fat to alter their metabolism. And many of these mice could serve as their own experimental controls. They had mechanisms inserted in their genomes which could turn their genetic defects on and off in response to substances in their mouse chow.

I’ll admit, when I heard about designer mice and their custom mouse chow, I got a little side-tracked. I had been eager to get out of medicine for a while. It all seemed so futile, and even a bit of a sham. Knockout mice might have been the ticket.

Two incidents elevated that thought to conscious consideration. The first was sighting a booth devoted to mouse chow in the exhibit hall.

To understand the significance of the chow booth, one must understand what the exhibit hall is all about. There is an exhibit hall at every conference. They are huge and opulent sometimes, sometimes modest, but always staffed by beautiful, shiny people and stocked with treats, from lattes to foam-model pancreases. Brands like Coach or Louis V. would feel at home amongst the booths.

Giant pharmaceutical companies ruled the hall, and the mouse kibble guys were right there in the mix. If mouse chow could buy an exhibit booth, the mice themselves must be golden.

The second incident was a conversation overheard in the poster hall.

The poster hall is a huge open space with row upon row of cork boards. Researchers pin up posters with summaries of their investigations on the boards, and attendees walk up and down the rows soaking in the knowledge. Usually there is a clearing in the middle with a nest of round banquet tables where everyone can go to take a break, chat and have a cup of pharma coffee. That’s where I sat while my wife presented her poster. I did not sit randomly.

As I walked up on the tables, I spotted a fat man in a plaid shirt and a yarmulke leaning in to say something to a thin, swarthy, bearded companion wearing a dark olive sport coat and a gold medallion. I needed in on that conversation, so I settled in the chair next to them, and swirled my coffee thoughtfully. Imagine my surprise as I picked up on the subject of their conspiracy.

“Yes,” said the fat man, ” I have been trying to find some of those mice. I need them to finish my work, but you can’t find them anywhere.”

“Yes,” echoed his friend, “those mice are nowhere to be found.”

“The closest I came,” the fat man continued, “was this Korean lady in San Fransisco. She said she had some, even said she would send me a few. But she never came through, and now I can’t get a hold of her anymore.”

The mice must be golden.

But my dreams of becoming a mouse Baron were short-lived. Upon further investigation, I found that genetically altered mice did not thrive. It was hard enough to get them past the embryonic stage. Once they could breathe on their own, they often required special conditions and diets just to survive. Worst of all, most of the really good mice had been patented. You bought the limited rights to a strain of mice when you bought the animals themselves. The patent system was the impetus for the black market discussion in the poster hall. You could trade for mice underground and avoid some costs, at the risk of incurring the wrath of the mouse factory lawyers after publication.

Despite the disappointment on economic grounds, I left the conference optimistic. I still had the image of all those colored bars from Dr. Collins’ slide in my head. Each one was a gene which a mouse model could exemplify, and therefore each one was potentially a druggable target. We had this. It was just a matter of time, and mice.

On my way to work, I have some time to think, though not too deeply. I leave early to beat the traffic, but I never do. Most commutes demand constant attention to collision avoidance. The situation is unfortunate, because the commute is the only time to think. Once work starts, I am behind. Someone constantly needs something from me to satisfy someone else who needs something from them, etc.. My workplace is carefully structured to facilitate this cycle. If I need to communicate with someone, odds are that I can lean over to one side and speak to them directly. Otherwise, my computer contains a messaging system which will pop in on whoever I need to inform or interrogate. Patient rooms cluster around my workstation, so I never need to walk more than 6 steps. However, patient contact occupies only a minor portion of my time. Most of the day is passed on the computer and the phone, addressing questions, requests and lab results. At the end of the day the freeway awaits again. By the time I get home, I am burned out and may or may not have it in me to do some physical training and watch television before retiring to get up and do it all again the next morning.

As luck would have it, traffic was light on the first day back from New Orleans. As I drove, I dreamed of druggable targets; Dr. Collins’ slides with the colored bars swam before me. Most of my patients were already on carefully targeted medications, but reaching down into the genome would ramp up medication effectiveness by orders of magnitude. Yet, not all my thoughts were so happy. Other images kept popping into my head, unbidden. I saw other colored slides, from another lecture by another renowned researcher. They were Dr. Brawley’s slides on the geographic and socioeconomic correlates of life expectancy and the epidemiology of conditions like obesity, cancer and diabetes. I could not banish those intrusive images, and by the time I was walking across the clinic parking lot, my mood had deteriorated.

I made it through the day, and finally got to resume my train of thought as I walked back to the car to drive home. I thought about gene targets and Dr. Brawley’s maps again. Then thoughts of one of the day’s patients joined the fray. She was very overweight, and had the metabolic problems that went with excess adipose tissue. She was on targeted therapy for her diabetes in the form of a monoclonal antibody directed at a counter-regulatory hormone receptor. It was the best science had to offer, but she often missed her doses. She had 2 jobs and no car, so she was up early and home late, and she simply forgot her meds sometimes. She set an alarm, but often could not attend to it, or forgot to reset it. We did not even discuss diet and exercise. She lived on a busy street with non-contiguous sidewalks, had no money for a gym, and no time to travel to a safe park. She could not cook, because she had grown up on packaged foods. In any case, she had grown too heavy by now. Her knees had given out under the weight. She could only mobilize fat stores in the face of severe calorie restriction. To reclaim  her life, assuming that was our aim, she would need two joint replacements and a gastric bypass.

I began to re-experience the rising panic which I had felt at the end of her appointment. Dr. Collins & Co. had let me down; I was not armed for this struggle, nor would I be. I stopped to take a breath and get my bearings. The parking lot was nearly empty. A bad smell rose from a nearby drainage grate, and a noise like water flowing.

I imagined that the noise might be something else. Maybe, instead of waste water, it was all those knockout mice, rising through the  sewers from the depths of the New Orleans convention center where the disappointments of Katrina had flowed down to bring the little fellows back, like a time-delayed Ghost Dance. The mice were coming with their little spectral incisors primed to clip down the cages, the labs, the chow booth, the convention center, and all the rest in a massive, surgical revision. I became convinced that the sound was the mice coming. It had to be. It was the only way that the knockout mice could save us.

What Did You Expect?

Did you expect that professional intelligence officers would involve a bunch of loud-mouthed incompetents in their operation?

Did you expect any persuasive evidence to come from an investigation for a population which, as Trump accurately estimated, would not change its vote if its candidate shot someone on 5th avenue?

Did you really need a conspiracy theory to convince you that the author of the Mexican rapist invasion, fine folks in the Neo-Nazi (Alt-right) ranks, Enemy of the People press, dictator admiration and non-stop smack/lies needed to be evicted from office and reviled in the histories?

Really?

Balance Impaired

 

DSC00176Close-up, the little gully evoked a strong sense of deja vu. The angle suggested that one might almost be able to stand up and walk it. The rock looked like a crocodile’s skin – all knobs and chunks with few cracks or pockets – and the few voids in the surface had formed from the erosion of yellow clay inclusions. I had been in this situation before, in the Canadian Rockies, the Tetons, the Cascades. It meant sparse and dubious protection for insecure climbing, with an ugly fall looming throughout.

The fresh memory of yesterday’s Eureka foray reinforced my unease. Just going into the mining country in Colorado’s San Juan mountains is sobering.  The road winds through acres of avalanche terrain peppered with jumbles of gray boards and rusty iron marking the eternal resting places of generations of abandoned avarice. Eureka itself stands for self-consciousness of our bitter relationship with the range. Once a small,  hopeful mining community the town is now a single building. The lone, windowless watchtower bears a prominent sign with the name of the town, placed there, no doubt, by the same sort of joker who might strap a party hat on a skeleton.

DSC00173

Yesterday was our second consecutive day at the ice climbs in the valley above the ghost town. The day before, we had been denied access to the longest climb in the area by an SAR exercise. Yesterday, we encountered a line of four parties on the same route, and we decided to trudge a bit further past the routes at the valley’s entrance. Around the bend and not far above, we found a lovely pillar of ice baking in the sun. The air temperature was cold however, and the ice looked to be in good shape from the ground, so we went for it.

My partner took the lead and ran the two pitches together. It went well until the very top. There he found the last few feet melted out and he could not get to the fixed anchor. Worse, in a fit of hubris, neither of us had thought to have him take the kit for building ice anchors. He put in two ice screws at his high point and I lowered him back to an intermediate ledge. He set up a belay and I set off to retrieve the ice screws and build an anchor in the ice to get us back down to the base.

Looking up at the situation, I knew that I should not risk falling. He had placed the two screws at the anchor properly. They had already held his weight on the lower. But the stainless steel tubes were basking. Many times, I had raced the process now at work on the anchor, placing another screw on a sunny climb before the last one heated up enough to melt loose. I arrived at the anchor and placed a back-up screw. Out of curiosity, I jiggled the anchor screws. They rattled in their holes, and by the time finished the rappel anchor, I could lift the screws free with two fingers.

DSC00159

By the time we got back down, the crowds had migrated our way. We had another objective in mind for the afternoon, but our hopes were squashed on the road, for we found a fellow standing at the head of the approach trail just staring across the valley as if he were reconsidering something. He informed us that he had ridden a slab avalanche for a few meters down the slope below our goal.  My partner had his wife and young son waiting back in Ouray anyhow.

DSC00163

There had been angst around bringing the child, who was their first. He was a nidus of concern in some familiar ways. He was 18 months old and did not want to eat or sleep regularly. He clearly understood everything said to him, but his only bit of expressive language was the word “No”. Each morning, he spent a non-stop hour on Rube-Goldberg action. Cups went into other cups, packets of jelly were transferred from person to person and then into the cups, and then back to their original owner. All of this chaos worried his parents. It seemed so overwhelming that one could hardly imagine any organized behavior arising from it.

Unless you had seen it before. I had. I distinctly recalled worrying about how I could possibly teach my first child to speak. I had no training, and no idea where to begin. Nevertheless, the kid started to talk. He had inherited the talent for it. From an adult perspective, it looked like a miracle, because adults liked to think that they had, each and every one, invented the world – or at worst discovered it. That way, the adult felt more competent, and the world seemed more solid.

From the child’s standpoint, he was building a constellation from the inside out. He had his experiences – what he might come to call ‘sense impressions’ should he grow into a particularly deluded adult – and he had the dots and lines to mark and tie together those experiences, inherited in his nucleic acids, language, and culture. The dots and lines were powerful tools. They would allow him to develop at heady pace, mapping out massive territories, like language, on the fly.

His ancestral mechanisms  assembled his star chart in a blur, and if he was at all self-conscious in his adulthood, he would spend a lot of time figuring out how he got there, and what kind of picture he had made with all those dots and lines overlying the bright spots of his experience. It would be daunting and he might be tempted to throw his hands up and just call the dots and lines the truth, to give the mathematical, linguistic and philosophical accretions on experience an undeserved solidity, while relegating the experience itself to a dirtier, incomplete status.

My partner’s son would have an antidote in that case. He would learn to climb, and that would at least open the blinds on the relationship between the picture of the stars and the stars themselves. He would still have to look, but most people didn’t even get that chance.

DSC00170

Perched in the little gully, I saw the true landscape.

I was not motivated. I felt the burden of all those extraneous considerations which populated the slope with angels and demons instead of little edges and blotches of ice. I climbed back down and handed the sharp end over to my partner. He was motivated, and managed to lead the pitch despite some misgivings about the security of the climbing. I followed without slips or fumbles. It was sketchy, no question. We looked at the next pitch, but decided against it. It would be there when the stars aligned favorably, or even better, when no one was thinking about the pattern of stars at their back.

The One Brute Fact

Even naming a brute fact, a Brute Fact, is the beginning of a mistake, but it can’t be helped.

Before I open my eyes, I am groping toward a mood. Some say that my mood will be nonintentional – that it will not be about something.

I disagree.

My mood will not have content, but it will stand in relation to something, in this case my unawareness at first, and then my time and place, and then where I left off before sleep. This ‘standing in relation’ – orientation in it’s most basic sense – is everything.

It is the bone of intention – the ‘aboutness’ itself, rather than the analysis of an intentional relation. It comes with consciousness and is not really distinguishable from consciousness. Logic (and its mathematical adjunct) models it, by permission.

Immediately, it yields identity and explanatory reduction. Further out, it leads to categories and theories. All this is natural to us, and renders meaningless terms like ‘supernatural’ and ‘separate mental substance’.

Curse You Peter Higgs

“Mass was so simple before you. Mass was just a property. Actually it was just a property of having another property: inertia. Inertia was so simple, though. It was just the property of resisting changes in motion.

Of course, we all know what ‘resisting’ means. And, we all know what motion is: d/t. If anyone must ask what distance and time are…well, there is little hope for someone so dim. At least, there is little hope for such a dimwit in physics. Hah! It looks like someone needs a metaphysician!”

The line of thought is a big hit with dualists. Actually, it is the best thing about mind/body dualism, and is why it’s good to have mind/body dualists around. Without them, physicalism grows too complacent.

The physicalist can be forgiven. It seems so obvious what we mean when we say that something is physical. But what does that mean? Is it simply anything that’s the proper business of physics? Is physics itself the proper business of physics?

The question of what makes something physical is actually difficult, even within physics. Take the Higgs field. It is not a ‘thing’; it is not even a ‘property’ of a ‘thing’. It is a property of space. It is a phenomenon which physics considers, but it is really weird, from the perspective of the old extended/unextended divide which Descartes proposed.

Yet we are prepared to accept the Higgs field as something physical, along with apples and atoms. That’s because we have been prepared to accept the physicality of the Higgs field by accepting  the physicality of things like d and t in the Newtonian scheme, as physical. Time and distance are not any less weird – they are strangely malleable, for instance – but they are more easily recognizable as our own phenomena. We experience time and distance, and we are comfortable with the idea that physics is a phenomenology of time and distance.

If we have drilled down to the notion of physics as phenomenology, and understand phenomena as our experience, then the remaining question is: What is our experience? I am not sure there is an all-encompassing answer to that question. Yet I think we can say a few things around the question which are instructive as to the notion of physicality.

At base, our experience is identity, and identity is interdependence. If I am watching an egg roll off the counter and hit the floor, I am the one watching that egg. The rolling egg, among other things, is making me, me. The memories of eggs, dependent upon the shape, color, texture and historical context of my current experience, shape my thoughts and expectations regarding the egg, just as the color, shape and texture of the egg depend upon the impression that the kitchen light delivers to my eyes after it bounces off the rolling egg. That is what the notion of supervenience is getting at: identity is fixed by spatial and temporal history.

And such a thing cannot be ‘transcendent’. It comes with the here and now; (physical) existence has a tense. ‘Tenseless’ existence is a product of reflection and not what we directly experience. Transcendence, in other words, occurs in the storybook, not in the story (else we would never read a story twice).

The trouble with this whole picture is that it looks like a truism. If physicality consists of an interdependent identity which avoids transcendence, then what is left? Ghosts are live possibilities; so are Higgs fields. Of course, that is the point of physicalism. When we look at our experience in total, physicality seems to exhaust all the explanatory possibilities, or at least the ones we could hope to know.

That Moment

scan0012

Every climber starts out believing in their own invulnerability. Death and injury happen to other people, because they are fools, suckers, or just don’t have the luck, like you do. Believing oneself impervious comes in very handy, especially during the formative years. In that era, every risk and critical action is still new.

The other ‘O.S’ route, North Ridge of the Grand Teton

You will take big run-outs whether you plan on it or not. You will make potentially fatal mistakes along the way. If you think nothing bad will happen to you, then you will march on past those moments of critical danger and learn the game. Of course, other outcomes are possible. Some people get the chop during the formative era. Some get bored with their apparently inevitable success and abandon the sport.

For everyone who sticks with it, there comes a moment when the belief in one’s invulnerability gets wiped away. For me, it was watching people die, and nearly being killed by the falling bodies. After that, there was no wishing my way back to the last age, where it couldn’t happen to me, no matter how convenient such a wishful belief may have been.

We can’t pick and choose what we believe in the end. No matter what, those moments come to spoil the utility of our delusions. Yet after the disappointment fades, you begin to understand: what you do after those moments is what really matters.

A Quick Defense of Fideism

First, consider the alternative: natural theology. It is a failure on two levels. On a technical basis, all the arguments which constitute natural theology rest upon a claim that God can be known in the same way that we know any subject of our experience. No matter how clever the argument, the basic  premise saddles a natural deity with some very limiting baggage – like an appointment book of times and places where the deity must be, with the associated activities and relationships. And, if the deity is the sort of fellow who can have an appointment book, then It is not the sort of fellow who can have all the limitless characteristics(?) which make a deity interesting.

Which leads to the level two problem: the arguments of natural theology lead to a deity who is completely uninteresting. Let’s say that someone came up with a cosmological argument which made sense, for instance. God is left with some familiar questions. It can’t tell anything about the source of Its motive by examining It’s creative act. It can’t say why It woke on our day #1 with the thought of creation in Its mind, any more than I can say why I looked at the ceiling fan when I opened my eyes this morning*. We are left with a God who is a guy. It’s a very powerful guy, but one who is in the same metaphysical boat as we are.

Two arguments are typically advanced to remedy the above situation. Let’s call them the Springboard argument and the Aspect argument. In the Springboard, we creep to the edge of an explanatory plank (think Aquinas’ contingency argument) and then launch to a conclusion by inference. For instance, the conclusion that, because we can’t abide an infinite regress of contingent causes, there must be a non-contingent cause at the source of causation.

In the Aspect argument, we are told that we may discover aspects of the deity by analysis of our experience, but that we should not expect to see Its whole structure due to our own limitations, though that structure is implied in the aspects.

The trouble is, neither of these arguments offer any explanation of what is in their remainders – the unexplained parts. In the Springboard, the remainders are things like an explanation of non-contingent causality. In the Aspect, the remainders are relations between things like intentionality and aseity or omnipresence. In other words, there is no account, in either the Springboard or the Aspect arguments, of the things lost in the guy-God conclusions of natural theology.

Implications are fine, but in the end, we need to be able to say what is implied, or we have gotten nowhere. Both the Springboard and the Aspect fail to give such an account, and we can see in their shared mode of failure, that they are actually the same argument. To understand an aspect of something which is unlimited and fully extant, is to understand nothing about “it”. To leap into an inexplicable conclusion, is to leap into the void.

But we are faced with voids no matter which way we turn. There are situations where we can’t climb out of our own skins (to borrow a phrase from Dr. Blackburn) to look into our own motives or the intelligibility of our experience. In those cases, no beliefs are possible, but assertions are as good as a shrug and a shake of the head.

So, if you feel that there must be something rather than nothing, nothing is stopping you. There.


*I can give a reductive explanation for what motivated me to look at the ceiling fan, but then I must explain my motive for reducing and explaining, and so on and so on…the motives seem to come first.

Shrimp Eyes

An answer to the post “What Is Knowledge?” at Self-Aware Patterns. If you don’t want to keep reading this, go read that…

—————————————————————————————————————————————–

Imagine…the mantis shrimp sees zorp. Zorp is a color beyond deep violet, and it is a color which humans cannot see, because humans only have 4 of the 16 color receptors which the mantis shrimp eye possesses.

Once upon a time, long before anyone looked inside a mantis shrimp’s eye, a group of marine biologists set out to test the shrimp’s sense of smell. In those days, nobody had looked in a shrimp’s nose either, to map out the nerves and chemical receptors. So, the only way that the biologists could learn about shrimp olfaction was to wave something smelly under a live animal’s nose and see what happened.

The experiment went like this: The shrimp entered a bare tank from an isolation chamber at one end. Prior to the shrimp entering, the biologists had secretly painted a random corner with an invisible, smelly substance. Upon release, if it swam to the marked corner, the shrimp got a treat.

After a bit of trial and error, the shrimp picked up the trick; it swam to the marked corner every time. Mantis shrimp had an acute sense of smell. But the truth is: mantis shrimp could not smell a damned thing. Unbeknownst to the investigators, the invisible, smelly substance which they used to mark the corner glowed zorp.

As it turned out, by sad, chemical coincidence everything smelly,  glowed zorp. Without understanding the micro-structure of mantis shrimp senses, the situation was hopeless. Only the shrimp would ever know the truth. Yet the biologists did know something. They got a predictive model of shrimp behavior out of their experiment. If they wanted to make shrimp bait, keep shrimp away from swimming areas, or start a shrimp circus, they had a reliable, practical theory to help them – they knew how to do it.

Furthermore, they did have some truth, even if it was not the shrimp’s truth. Because, the biologists stated the outcome of their experiment carefully.

Mantis shrimp were observed to preferentially swim to a corner marked with Fragrance 5 after receiving a standard shrimp kibble in association with alighting upon a Fragrance 5 mark in 3 previous instances.”

Obviously, the truth itself does not get you a shrimp circus or anything else. The truth, being blatant, does no work.

Yet we think that we seek the truth when we seek knowledge. We have been told that knowledge is justified, true belief. Indeed, the justification-belief relationship seems unbreakable. If justification is a well constructed story, then all our beliefs have it, as we have somehow arrived at those beliefs. And, we certainly distinguish between things we know and things we merely believe, on a functional basis, which is really just the strength of the justificatory tale.

Truth has little to do with justifications. Knowledge stands apart from mere belief when it does something – when it proves itself reliable. Reliability, like an onion, has no core, and so, knowledge doesn’t have a core either. Peel back a layer and you can aim a cannon. Under the next layer, you have a laser. Under the next, you find the mechanisms needed to build a global positioning system. The same structure undergirds our psychological theory of mind, introspective faculties, and our aesthetics. All those tales which bear re-telling constitute our knowledge.

Truth is just what we’re stuck with.

‘Cause You’re Doin’ it Wrong

Regarding thoughts and discussion of deity, the question must eventually arise, ” Why?”. Once one has decided not to take such notions too seriously, why engage on the matter with those who do?

Morbid curiosity is part of the answer. Or to paraphrase a famous psychologist’s response to the same question about his interest in UFO’s: I am more interested in the motives for holding the belief, than I am in the belief itself.

But beyond morbid curiosity, there is an ethical impetus. For within the mish-mash of desperate apology and cognitive dissonance, lies a kernel of consistency. It begins with the question, “Why is there something rather than nothing?”

It is a ridiculous question, but the reason why it is ridiculous is interesting. We are in the world and can never step outside to see whether the world must be as it is, what other way it might be, or whether it must be at all. In light of our blindness on the matter, an assertion of existential necessity appears to need no further justification. And that’s good, because nothing explains (existential necessity) God, though (existential necessity) God explains everything  – if you believe it. And that’s as far as it goes, for those few who are ethically sound.

For the rest, they go on to endow existential necessity with intentionality, motive and any number of other, inconsistent properties, all as a way of swinging their dicks around  (to allay their own anxieties, most often). That is doing it wrong, and I just hate to see folks doing it wrong.
