Welcome to Episode 18 of the series Philosophy Unveiled, by the author Lane Friesen. I m Rachel and I m doing the reading today.In the last episode, we demonstrated that the brain is capable of discovering science. We saw that the scientific method involves a kind of cascading analysis through three critical loops Observation, Reflection and iNtuition. We examined the interaction of these circuits with other loops such as Thinking and Understanding. We also introduced three distinct ways in which this processing is coordinated. First, there is the Reason loop and its consciousness. This gathers and coordinates the results of independent cognition, in the various strategies that are represented by the differing cognitive styles, and it formulates the result into a speech stream. Reason therefore needs words in order to think. We suggested that Reason is ruled by Facilitator thought.Then, we introduced common sense, and suggested that it is formulated within the Weltanschauung or Worldview circuit. This Weltanschauung loop provides the mind with an updated model of the external world, so that it can adapt thought and action to altered conditions. We saw that Weltanschauung depends strongly upon an ongoing Teacher understanding and Mercy identification when these elements are missing, then the mind becomes very inflexible.Finally, we suggested that both reason and common sense interact with being. This being, as we have presented it thus far, comes in two flavors Kinship is one variant. A good example of being that is based in Kinship might be citizenship in some nation state. For instance, my nationality is Canadian that s part of my Kinship-based being. The unique thing about Kinship is that it is relatively insensitive to the size of the Kinship-based social grouping. Suppose, for example, that we placed 100 Canadians in a room, and then separated them into two groups, each with 50 Canadians. It wouldn t make any difference to the individuals themselves they d still all remain equally Canadian. Or, suppose that we formed a club of birdwatchers. Let s say it had 100 members. Then, we split the group into two and moved them apart. We d now have two sets of birdwatchers, each with 50 members. Both groupings could still have the same kinds of club meetings, and still go out to watch the same sorts of birds it wouldn t make any difference to the members at all, as far as their bird-watching was concerned, if they were part of the larger group, or one of the two smaller off-shoots. That s how Kinship works.Let s look now at an example of being that is based in Dasein. In contrast to Kinship, Dasein cares very much about diversity, and thus also about size. We might imagine the city of Vancouver, British Columbia, for instance, divided into two by an impassible barrier. It would be a disaster. A resident s home might be in one half, and his employer in the other he would either be homeless, or out of a job. If hospitals happened to end up on one side of the division, then the people in the other half would have health care challenges. That s how it works with the being of Dasein. Whenever an interlocking Dasein group is split, then the Dasein or being of each member is degraded, for Dasein interaction is based in the mutual beneficial exchange of specialized abilities.So, let s put it together. The waking mind is integrated, first of all, by Reason and its consciousness the logic of this reason is expressed in speech, and is consistent with science. The reasonableness of Reason is adjusted in turn by Weltanschauung and its common sense. Finally, upon a foundation of consciousness and common sense, being develops. This being may base itself in a commonality of Kinship nationalism here would be a good example. Being in contrast may develop further into an interpersonal division of labor, and involve Dasein with its globalized division of labor. That brings us finally to the topic for this episode I d like to look at the economic implications of Dasein-based being.Now, Martin Heidegger indicates that being always involves a transfer of data from C(l) to F(l) he calls this flow of data an assertion, and he suggests that it can lead to speech. What happens when Kinship takes a stand on its being, by moving information from C(l) to F(l)? Well, let s suppose that a Canadian hockey team won a gold medal in hockey at the Olympics. If a Canadian were hiking in the woods, and he heard the news, then he would probably cheer; if fifty Canadians were watching the event together in a room, then they also might all cheer. These many Canadians would of course all be taking an individual stand on their being, when they cheered, but they would be doing so in a manner that made the size of the group relatively unimportant. That s Kinship.It s very different with Dasein and its division of labor. Suppose, for instance, that I wish to take a stand on my being by putting my words into a book. I will require readers who do not know what I know. Factories must construct a computer for people like me; power companies will need to supply electricity. For every person like me who decides to write, there must in fact be multiple thousands of individuals with skills that are very different. The being of Dasein, unlike Kinship, thrives as diversity grows. Any schism in a Dasein-oriented group can easily be world- or Weltanschauung-shattering to the Daseins of those disparate individuals who make up the social grouping their separate beings or Daseins may also dissolve and disappear.Parenthetically, if we are familiar with sociology, then we might link at this point to Emile Durkheim and his distinction between mechanical solidarity and organic solidarity it is precisely our current distinction between Kinship and Dasein that he is discussing.OK, let s examine the being of Dasein more closely. We ll start with a point that I introduced in the last episode left hemisphere Contributor C(l) and right hemisphere Contributor C(r) always take a stand as a pair that is, whenever C(l) sends information to F(l), then C(r) quickly sends data also to F(r).What is the significance of this pairing of C(l) and C(r)? Well, it turns out that a C(l) stand on its being, or a data transfer from C(l) to F(l), is seen by the mind as an if. In mathematics, an if is always followed by a then, and it is precisely this then which is the function of C(r). The resulting if-then structure - if we supply the correct set of ANDs and ORs - turns out to define a logic processor. And, linguists tell us that all of speech is based in very simple logic five operators, eight inferences, and a set of replacements so, if we wished to turn to mathematics, we could then work out how the mind formulates speech.Now, we might wonder, Why does right hemisphere Contributor C(r) handle the then, but not the if. It s because this right hemisphere Contributor C(r) region chains logical statements or objects together into plans, using what mathematics would call AND structures, and these define a sequential memory addressing scheme, and that does not easily relocate itself. For instance, we might imagine sheets of paper as they were chained together in a roll of toilet paper. Suppose we were asked to move from sheet 24 to sheet 258. We would have to find some place where we could unroll the paper, and then we would have to walk along the roll of sheets, until we arrived at our destination.It is the left hemisphere C(l) that initiates the logical if it does this by taking what Heidegger calls a stand on its being. It can do this very flexibly because it deals with branched ORs, and these set up a random addressing memory system. It would be like having sheets of paper bound into a book, rather than chained in a roll we would then be able to flip instantly from page 24 to page 258.What does all of this have to do with economics? Well, what do we do in a market system? If my neighbor owns a shovel, and I need to clear the snow from my driveway, then I can trade the use of my skis for his shovel, and both of us will get the job done. Can Kinship make this kind of an exchange? No, because Kinship assumes that everyone is similar. I have a shovel; you have a shovel; we all have shovels. If there is only one shovel, then it is owned communally. It is when my neighbor has a shovel, and he owns it, and I don t, that Dasein triggers. We conclude that Dasein with its if-then logic is very critically related to modern economics.OK, let s move further. We stated in previous episodes that C(l), where Dasein originates, is the home of the will. How does this will operate? Does it choose our actions? Well, not directly. Contrary to what most of us might think, will does not generate an action signal. It is Server and Perceiver strategies, within the left and the right superior parietal regions respectively, that generate go signals for action: Single-cell recordings in go no-go paradigms have shown that superior parietal neurons in macaques [monkeys] code the 'intention-to-move' during no-go trials. Perceiver strategy turns out to play a particularly crucial role in these action decisions: Our data suggest that the right superior parietal cortex [Perceiver] seems to play a key role in inter-hemispheric visuo-motor integration and that the nature of the information transferred that best correlates with the CUD [Crossed-Uncrossed Difference] is a 'motor intention'. Of course, we might have deduced this fact from our previous discussion of Dissociative Observation Perceiver strategy can play internally with alternate reality, and at the same time block the associated actions. It does this by neglecting to transmit a motor intention. So, if will in C(l) does not initiate action, then what does it do? Let s not forget that C(l) initiates the logical if s within the mind that s a very big thing. Moreover, since C(l) is constructed upon OR s, similar to the pages in a book, C(l) also controls the random access machinery of logical memory this allows it to direct the underlying context of action, and in this way to guide C(r) means to meet C(l) ends.Let s look more closely at how it fits together. Planning for action, we notice first of all, takes place in right hemisphere imaginative Contributor C(r). We read: Our findings indicate that the DLPFC [dorsolateral prefrontal cortex, or Contributor] contributes to the mnemonic [memory] processing, and above all, to the preparatory set [of sequenced actions being planned by] this activation, which was restricted to the right DLPFC [and thus C(r)]. The results of right hemisphere Contributor C(r) planning are delivered in turn to an area in the right hemisphere called the frontal eye field, or FEF. We read: Regarding the premotor areas, when activation maps obtained in this condition were superimposed on anatomical images, we found that the right premotor activation observed during the delay phase [when planning takes place] was located partly in a cortical region where the precentral and the superior frontal sulci intersect, an area that may include the right frontal eye field (FEF) in human. Research confirms that right hemisphere planning is visually imaginative: The persistence of significant activation in the premotor area during the delay may indicate a spatial rehearsal , as subjects have to mentally shift their attention from one target to another within the visual sequence maintained in mind. As soon as right hemisphere Contributor C(r) and the right frontal eye field have succeeded in chaining together a projected plan, then the results are transferred to the left hemisphere frontal eye field. Neurology confirms: The right dorsolateral prefrontal cortex (DLPFC) [or C(r)], the left frontal eye field (FEF) [which works with C(l)], the right precuneus and cuneus, and the left cerebellum were activated by both visual search and memory search. We suggest that the right DLPFC [dorsolateral prefrontal cortex, or C(r)] is associated with the process of monitoring and manipulating multiple elements, while the left FEF [left frontal eye field, which works with C(l)] is involved in cognitive planning. How is C(r) planning, as it shapes itself in the twin frontal eye fields, implemented by C(l)? It turns out that C(l) suppresses all actions except the first step in the C(r)-developed chain, then, when the first step has been performed, it suppresses the first step and releases the second step, and so on throughout the sequence. Again, this is consistent with neurology: We conclude that left DLPFC [dorsolateral prefrontal cortex, or C(l)] activation is involved directly in cognitive switching, in conjunction with parietal [Perceiver and Server] and temporal [Teacher and Mercy] brain regions [which participate in the model-building Weltanschauung]. So, we have arrived finally at a description of will as it operates in C(l). Left hemisphere Contributor C(l) will, when it takes a stand on its being, imposes a mask that suppresses or grays out all elements except the one being noticed. Researchers confirm that C(l) choice involves the suppression of alternatives: With all levels of constraint combined, significant greater activation was observed in the left DLPFC [dorsolateral prefrontal cortex] (BA46/9) [C(l)] under the suppression condition we argue that the most likely single cognitive function of the DLPFC [dorsolateral prefrontal cortex] is to specify a set of responses suitable for a given task and to bias these for selection (sculpting the response space). Moving to mathematics, we might say that a choice of A by C(l) deselects the disjunctive complement of A within the left hemisphere OR structure of memory. This characteristic turns out to be crucial to the architecture of the brain as a logic processor.OK, let s summarize. Perceiver and Server strategies are sufficient to perform single isolated actions: The magnetoencephalographic signal was collected in a visually guided response-finger selection GO/NOGO task. The minimum norm distributed source analysis identified the sources in bilateral superior parietal lobules (SPL) [Server and Perceiver], with stronger activity for contralateral finger movement. Our results suggest that the human SPL [superior parietal lobule; or Server in the left hemisphere, and Perceiver in the right hemisphere] plays a role in the spatial selection in a visuomotor task similar to that identified recently in monkeys. Putting it together, Perceiver analysis can therefore release habits, and Server strategy, as we will see in another episode, can mimic actions this Server trait in particular allows the brain to boot up through initial stages of childhood development.Any sequencing of these Perceiver- and Server-directed actions, though, involves Contributor strategy: A parietal-premotor network is sufficient to store visual temporo-spatial sequences in STM [short-term memory]; and, in situations when the planning and preparing of a predictable sequence of actions is required, then the DLPFC [dorsolateral prefrontal cortex] might be recruited. As action proceeds, the right hemisphere dorsolateral C(r) region observes changes in the environment, as they are reported perhaps by Weltanschauung, and adjusts the plan as necessary to adapt to them: This result is important as it shows, for the first time, that conscious change perception is associated with normal activity in the right DLPF [dorsolateral prefrontal, or C(r)] cortex. The left hemisphere Contributor C(l) area on its part scans through the OR structure of planning and memory, and moves to alternatives or contingencies as necessary. Each time that one element is explored by C(l), the rest is grayed out into darkness. Heidegger as a Contributor confirms to us that a focus by C(l) on some particular characteristic causes the rest of what is seen by his mind to become dim; he states that this graying out is accompanied by a kind of focusing or zooming in.Alright, we ve now identified the start button in the brain for economics. It is the will in left hemisphere Contributor C(l), located in the dorsolateral area 46, working in conjunction with the frontal eye fields: Brodmann area 46 [or Contributor] seems to be associated with the selection of response, whereas areas 9 and 8 [FEF, or frontal eye field] seem crucial for the maintenance of the representations. That brings us to another question. What is it that controls this top level C(l) controller? The answer is surprising. We are told by one researcher that imaging studies of cue-induced craving suggest that craving is mediated by several brain substrates, which include the left dorsolateral prefrontal cortex [or C(l)]. Another confirms that cocaine users activated the anterior cingulate [Facilitator] and left dorsolateral prefrontal [C(l)] cortices. This dorsolateral region responds to food as well as to drugs: A novel finding in this study was a highly significant response to taste in the dorsolateral prefrontal cortex. If the if-then structure in the left dorsolateral region, or C(l), does not activate, then we will eat even when we are not hungry: Compared with lean men, obese men had consistently less postprandial [after meal] activation in the left dorsolateral prefrontal cortex, irrespective of meal size. We conclude that biological needs, as well as cravings, are all mediated by the C(l) left hemisphere dorsolateral region. Let s think about that for a moment. If C(l) should ever operate by itself, without some kind of Kinship or Dasein structure of being that could harness its initiatives, then the result might well be social disaster. History in fact confirms to us that this is exactly what happens. Facilitator philosopher Thomas Hobbes, for instance, lived during one time when the Kinship of the Middle Ages and its absolute monarchy had broken down, and the Dasein of a modern exchange economy had not yet developed; he pictured the result of a broken society: There is no place for industry, because the fruit thereof is uncertain: and consequently no culture of the earth; no navigation, nor use of the commodities that may be imported by sea; no commodious building; no instruments of moving and removing such things as require much force; no knowledge of the face of the earth; no account of time; no arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short It may seem strange to some man that has not well weighed these things that Nature should thus dissociate and render men apt to invade and destroy one another. Today also, those who break up a primitive Kinship-based social system can find that the result is an ungovernable mass of individuals, and a failed state.So, economics must involve a form of being, if it is to trigger within a social grouping, and that means a transfer of data from C(l) to a cognitive F(l), in the minds of those individuals that make up the group. So, let s move our attention to the left hemisphere anterior cingulate F(l) region. We confirm, first of all, that it is very much involved in the C(l)-C(r) if-then logic system. Here s a quote, which I will read, and then summarize: The spatiotemporal analysis of brain activation during the execution of conditional reasoning tasks (the four inference forms: Modus Ponens (MP), Modus Tollens (MT), affirming the consequent (AC), and denying the antecedent (DA)) was performed Dipole source analysis of the difference wave (MP-BS) suggested that a generator localized in the left anterior cingulate cortex (BA 24) [or F(l)] was involved in the activation and the application of the inference rules. ERP components of the five tasks were similar in the subsequent time period between 700 and 1700 ms. Following that period, a greater negativity in the reasoning tasks, in comparison to the BS [baseline] task, developed between 1700 and 2000 ms poststimulus over the left fronto-central scalp regions. A generator of this effect was located in the right anterior cingulate cortex (BA 24) [or F(r)] and was possibly related to cognitive control. The results indicate that the cingulate cortex was activated by conditional reasoning tasks. Summarizing, F(l) appears to process the If of a C(l)-initiated If-then, and about a second later, F(r) will then process the then. Now, let s not forget a very important condition: F(l) and F(r) will do these tasks if these twin Facilitator regions have become cognitive within the mind.Let s move further. What does the left hemisphere Facilitator F(l) area do, when it is cognitive? How does it process the C(l) if ? We ve suggested previously that the F(l) segment calculates utility. Jeremy Bentham the Facilitator philosopher characterized utility as a measure of happiness. This orientation is confirmed by researchers: Using a backward masking procedure similar to that of previous studies, we used functional magnetic resonance imaging (fMRI) to study the amygdala and anterior cingulate gyrus during preattentive presentations of sad and happy facial affect. Conjunction analysis showed that masked affect perception, regardless of emotional valence [sad or happy], was associated with greater activation within the left amygdala and left anterior cingulate [or F(l)]. Another confirms: During presentation of happy facial expressions, we detected a signal increase predominantly in the left anterior cingulate gyrus [or F(l)], bilateral posterior cingulate gyri, medial frontal cortex and right supramarginal gyrus, brain regions previously implicated in visuospatial and emotion processing tasks. When this F(l) region stops operating, then the result is depression, and that certainly is not a very happy state: Major depressed patients with psychotic features showed decreased rCBF [regional cerebral blood flow] in the left subgenual anterior cingulate cortex [F(l)] relative to both non-psychotic patients and healthy controls. Jeremy Bentham thought that F(l)-generated utility could be calculated as an absolute number, such as four units of happiness, or perhaps five units of happiness, but modern theorists agree that one can do no better than generate an ordering of utility or happiness, based upon comparisons A, for instance, leads to more happiness than does B.Alright, I d now like to bring in E(l), or left hemisphere Exhorter strategy. According to our diagram, it connects directly to C(l), and thus to the will. What does this E(l) region do? Interestingly, neurology tells us that it stops things from happening. We read: Go-P3 was located mainly in the medial part of the parietal cortex [Server and Perceiver], whereas the NoGo-P3 activity was observed in the left lateral orbitofrontal cortex [E(l)]. Now, this is very interesting information. We ve seen that a C(l) focus on some entity grays out what is not being viewed; using the figure of a clearing in a forest, C(l) concern draws the trees nearer, and makes the clearing smaller. The more C(l) is concerned about some particular issue, the tighter is the focus of this attention. If the action is not desired, then this may be counter-productive: C(l) concern can channel thought into the action, and this might end up pushing the mind to pursue it more aggressively. Left hemisphere Exhorter E(l) and its Character loop, in contrast to C(l), moderate the action itself. E(l) can thus bring habits under control.Previously, we saw that right hemisphere Exhorter E(r), with its potential Discernment, was the cognitive generator for sexual excitement, and the engine behind Habit. We notice now that left hemisphere Exhorter E(l) with its Character, when it becomes cognitive, is a balancing entity that can shape this activity.How is this done? Exhorter E(l) motivational urging is sensed by left hemisphere Contributor C(l) as mood. Martin Heidegger the Contributor philosopher tells us that mood is like the water in which a fish is swimming, and that it deeply influences Contributor choices. Neurology again confirms this: Alteration of mood is associated with activation of orbitofrontal cortex [or Exhorter] which may be critical to the experience of emotion. Let s expand our view for a moment. I d like to point out that we ve just covered the elements of the Perceiving loop. Martin Heidegger and Immanuel Kant indicate that this Perceiving region resonates with meaning, both in listening and in speaking. It is a combination of meaning in the Perceiving loop, and mood as it develops within the Character circuit, that reaches up to C(l), and helps it decide what matters. Let s apply this new machinery now to economics. C(l), as we have seen, mediates desire. This may include basic needs such as hunger or thirst. The Habit loop might be operative. The Feeling circuit plays an important role, and at some point we will analyze it more closely. C(l) and its will focus this mix of desires, by suppressing or graying out alternatives. As we said, whenever C(l) places the spotlight of its attention onto something, this tends to channel thought into that highlighted region, and the mind as a result will move in that direction that s how C(l) will works. It leads to an important principle: As far as the mind is concerned, more is generally better.C(l) choice in turn influences F(l) it is at this next F(l) level, in the calculation of F(l) utility, that things again have an opportunity to become more balanced.Generally, as more and more is acquired, a level is found at which satisfaction or satiation occurs. Soon after that, less is better. For instance, if one spoonful of ice-cream is good, then two are better. However, after twenty-five spoonfuls, we might feel that we have perhaps had enough, and that another spoonful would not make us more happy. We could tolerate it; it would not yet decrease our happiness, but neither would it increase it. We have in this way arrived at a peak in the utility curve that is calculated by F(l). The marginal utility, or the increase in utility from the last spoonful to the last spoonful plus one more, is now nothing. In mathematical terms, the first derivative or rate of change of the utility curve is zero, and we are thus maximally happy. That s how economics works in the left hemisphere.All goods that can be had in abundance may in this way be brought to a maximum, and from then on they will no longer be noticed by the human mind. They in fact become totally invisible in Heidegger s language, they vanish into the background of what is suppressed by C(l). That s why diamonds are more valuable than water, even though water is crucial to life, and diamonds are not. The supply of water is unlimited, and too much water is harmful to the health, and so by taking all that we want and then no more, we easily maximize the utility curve of our water use. Water then ceases completely to be part of our mental calculations; it becomes transparent to us. The supply of diamonds in contrast is limited, and because others have them, and we see them and want them, preference from Mercy thought and Feeling may cause them to become very highly valued indeed. [Water is now becoming more limited, in many parts of the world, and we can thus expect the human mind to begin to optimize its use, as it does with diamonds. This will lead to a very different kind of existence.]Let s suppose, though, that we cannot take all that we wish. Perhaps there is an associated cost and our budget is limited. C(l) in this case can release a focus on a substitute the unavailable item will be grayed out, and the substitute is now left unsuppressed. If we can choose Coke in a can or Coke in a bottle, for instance, and Coke in a can is less expensive, then we will take as much as we can afford of Coke in the can, and the Coke in the bottle will not be noticed by our mind, and this once more will be the end of the matter.Heidegger tells us that this sort of initiative on the part of C(l) is not only the shaping of a potential action set by means of the elimination of alternatives, but also an assertion in preparation for speech it means that F(l) and its Reason loop speech stream could now perhaps be exploited to instruct others to perform some action. Alternatively, we could listen to instruction from others, and their words would generate meaning within the Perceiving loop, and we might carry out actions. We could in fact attempt to maximize the utility or happiness of the group as a whole that is what Jeremy Bentham the Facilitator philosopher wanted to do.But, we ve just missed an important point. What is it in the mind that prevents us from exceeding our budget? It is Perceiver strategy that prevents this, as it is accessed through the Thinking loop, and operating as part of Judging and conscience.And, if Perceiver analysis will not do the job, then the task of imposing budgetary discipline reverts to right hemisphere Mercy thought, with its Feeling circuit. Emile Durkheim speaks of this as a move from restitutive to punitive law.I d like to perhaps make one comment about this. If the mind is forced to revert to Feeling, in order to enforce a contract, then we notice that Perceiving can no longer operate as an independent circuit. That s because Feeling causes data to flow from F(l) to C(l), rather than in the opposite C(l) to F(l) direction, as occurs during Thinking.However, it is possible for Perceiving and Feeling to operate together as a hybrid circuit I call this loop Value. We notice several things. First, C(l) in Value is no longer taking a stand on its being, and thus both Kinship and Dasein begin to break up this will affect the social order. Second, communication is not going to be as effective, for meaning cannot resonate properly within Perceiving; speech in particular will become less logical. Third, being will begin to center around Mercy identification, which senses characteristics of objects in the external physical world. Retribution for those who violate contract will thus involve personal acts of violence against the external physical body of the perpetrator he will be hanged in public, drawn and quartered, burned in hot oil, or have his hands cut off. The Value loop, when it is used to enforce contract in this way, can easily turn into a Vengeance circuit.OK, let s move back to our topic, and examine Dasein itself, in its role as an economics machine. Let s suppose that C(l) is hungry, and C(r) in response develops a plan for baking bread. The right hemisphere and its C(r) are spatial, and the elements or objects of the C(r) plan will therefore link together into a spatial sequence, as we might perhaps present them in a workflow chart. This information is passed to the left hemisphere. C(l) can now choose to release from grayness the first element, in preparation for implementation this C(l) choice, as it passes from one element to the next in the C(r)-developed plan, will alter right hemisphere C(r) space into left hemisphere C(l) time.What happens now? Martin Heidegger indicates that C(l), as it prepares for the first step of making the bread, will reach out the hand automatically and unthinkingly for flour, under the assumption that it is ready to hand this reaching out will be one of the habits that are located within the Contingency loop. C(l) will assume, in its absorbed coping, that the flour is present. However, let us suppose that the flour bin is empty. Someone has used flour, while we were gone, and we didn t know about it. The flour will now become unready to hand. C(l) in response will release the grayness that covered the flour bin, and the mind will become aware of the flour. In particular, it will see that the flour bin is empty. Flour in our current context is a for making bread entity that is its essence - and now it is too scarce. If our action context had been something else, then the mind wouldn t have noticed. However, things have now been brought to its attention.In a similar way, we might never notice the windows in a room until it became too hot, at which time we would look around for some way to cool things down, and might perhaps glance over to see if the windows could be opened windows in this case would alter into air-cooling things. If we wished to exit the room, then we would be drawn to the door, and if the handle was stuck, then suddenly our entire consciousness would become aware of the handle, and it would fill our mind, so that we would separate from it as a subject, and look upon it as an object.Now, what could cause us to become aware of the flour bin, or the door handle, to the point that we might actually separate from it, and create a distinction between the subject which is us, and the object which is the bin or the door handle? The cause is a transition of the noticed and ungrayed unready to hand aspect from the left hemisphere and F(l) in our current example we are talking about an empty flour bin - to an item in the right hemisphere, which we recall is the home of Locke the Perceiver s object binding, and also the location for Descartes separation of observer from raw sensory input.How does this transfer take place? Martin Heidegger speaks of it as de-worlding. Let s examine the process. Before the problem emerged, C(l) absorbed coping or dealing was drawing data flow from F(l) downwards to C(l) it was a direction that was compatible with Feeling. However, C(l) absorbed coping or dealing with bread-making has been interrupted by a flour bin that is unready to hand. C(l) in response prepares to take a stand on its being. This reverses the flow of information between C(l) to F(l) from what it normally is in Feeling and its absorbed coping, and causes the Thinking loop to take over. Whenever the Thinking circuit operates, then some aspect within F(l) will stand out, within the current context. This noticed essence, with its adverbial too scarce or not working aspect is passed to Perceiver strategy by means of ISTP. Perceiver analysis, we have suggested in previous episodes, is responsible for object binding, and it begins to process the associated information, and C(r) revises its plan in the light of the sudden C(l) focus.Now, why is it necessary for the information transfer to take place in this sort of a complex way? Why is it not sufficient for F(l) simply to point at an object, and tell C(r) directly that a plan must be revised, in order to meet some problem that is unready to hand ? Why must the process be mediated by Thinking and its powerful deductive logic and syllogistic machinery? In particular, why must the final stage of the transfer move through Perceiver belief? I ll use an illustration that comes from Professor Hubert Dreyfus of the University of California in Berkeley; this scholar is one of the world s leading experts on the philosophy of Martin Heidegger. Let s imagine that we wish to give a lecture to 13 people, and we are assigned a classroom and told that there will be 13 chairs in the room. However, we walk in, and we see that the chairs are in boxes, and that the lecture is about to begin. Are there 13 chairs? In the current context, no, there are not. Or, let s suppose that the chairs have come from a local museum, and they have signs attached which state, Antique. Do not use. Are there 13 chairs? What if some of the chairs are broken? Or, what if chairs are present, and the students walk in, and one of them weighs 350 pounds, and it is not certain that the chairs will tolerate this weight? Logic is evidently necessary, and in some cases this logic will need to be modified by aspects of belief. The mind, it turns out, is quite capable of doing this processing.If necessary, Thinking can iterate back to the left hemisphere by means of ESTP, and send data around the loop a second time. It can initiate conversation with someone else, as data passes from C(l) to F(l), and solicit their opinion. It can even ponder the meaning of their words within the Perceiving loop. When all is said and done, Perceiver belief delivers the conclusions to C(r).In this way, left hemisphere C(l) and right hemisphere C(r) are coordinated by Perceiver analysis, so that both are looking at a similar object, which is the element in the C(l) sequence which is currently unready to hand in the context of the current action sequence.What happens next? The right hemisphere frontal eye fields and right hemisphere C(r) are responsible for visual saccades, or eye movements, and they do this searching in real time, as needs arise: Right dorsolateral prefrontal cortex was involved in goal-directed visual search, but showed no delay activity [in other words, the searching was done in real time]. The eyes look, and let s suppose they see that flour is located nearby, in a bag that is owned by a neighbor. In Martin Heidegger s terms, the neighbor s flour is right hemisphere present at hand. It isn t yet left hemisphere ready to hand, because it belongs to my neighbor, but it certainly is right hemisphere present at hand. Now, that brings us to the question of ownership. How does that work? John Locke the Perceiver tells us that ownership results when we mix our labor with some object. Adam Smith, a Contributor economist, speaks in turn of the labor theory of value. Perceiver strategy deals with links, and Locke tells u |
