"For some time, I’ve been working on comics as integrating the sequential and simultaneous reading modes, but it was through Lynda Barry’s blog for her class on creativity that I came across Iain McGilchrist’s work on the brain. In short, McGilchrist dispenses with the old left/right verbal/visual distinction and talks instead about them as fundamentally different ways of perceiving – which more or less correspond to sequential and simultaneous. Pieces just started to synch together. The background brain image refers back to the hierarchical tree/rhizome distinction from earlier in the chapter, which also aligns with this way of thinking about the hemispheres."
"I will say that I agree with you, Samuel, that Iain McGilchrist is a bit of a close-minded curmudgeon when it comes to language, politics, identity, political correctness, and changing social mores in politically progressive circles… which I find comprehensible on the one hand, given his own social and intellectual background and the perspectival limitations inherent therein; but on other hand, I think his research and conclusions—which I find quite profound, engaging, and true—what with his engagement with brilliant thinkers like German Romantic philosophers, William James, Alfred North Whitehead, that point towards the processual nature of life, the relational nature of Being and perception as it exists in the direct encounter of consciousness, and the isolating effects of rationality when employed in a dissecting manner as the basis of an anti-metaphysics metaphysics (aka scientism). With this said, I think that one could make a devastating critique of his own Traditionalism by appealing to the same logic of his own research’s conclusions! Because all things flow, because being is relational (and not absolute), there ought to be more of an allowance for change, fluctuation, and evolution in our language for understanding identity and historical interpretation, which more Traditionalist minds might see as “destructive of Western culture,” or whatever. I think McGilchrist’s major flaw is his own unwillingness to allow his conclusions to penetrate into all arenas of intellectual and political history, not just those that he himself is comfortable with allowing it to make a change. To me, this is a charitable critique: pointing out the importance, profundity, and validity of his research, while also demonstrating that the author has blindspots that might otherwise be made visible and repaired if he were to open up parts of his thinking that have not yet come to fully accept his own conclusions."

McGilchrist: "One group of people say "The neuroscience is very interesting, no problem with that, but then you start trying to relate it to the world of ideas, and I'm not comfortable with that". And another group says "The analysis of civilizational history is fascinating, but I don't think it really needs all this neuroscience." So you get these two factions, each of them saying "As far as our stuff goes, yes, that's right. But why put these together?" Now that is fascinating, because I think it's part of the way in which our whole intellectual world has fallen apart into silos. ...If each of us just carry on taking a very particular stance, we won't be able to see what is going on as a whole, and it's that that needs to be seen. You know, we talk about the metacrisis. There's not just a crisis in what we're doing to the natural world, and another crisis to do with the fragmentation of society, and mental illness, and so on. They all come together. And they come together, for me, in something that is profoundly illuminated by hemisphere theory."

McGilchrist's Duke University lecture is a sustained critique of the machine metaphor. To understand why, we need to recognize that a recurring theme in his work is drawing out the contrast between opposing positions. And so here he highlights the opposition between the "machine metaphor" and the "organism metaphor" (all language is metaphor). This might chafe a bit with his friend Michael Levin, who is engaged in work that attempts to close that gap, and not emphasize the differences, thereby effectively reducing the opposition between these metaphors. So when McGilchrist concludes "Machines can never be like people, but I worry that people might be becoming more like machines with every passing day," that is a sentence you will probably never hear Michael Levin say.
Why doesn't McGilchrist, like Levin, emphasize the similarities? It all goes back to those strikingly different lateralized phenomenologies at the heart of the hemisphere hypothesis, each of which better correlates with one of those metaphors. And because those phenomenologies, and how the allow us to understand both ourselves and the world around us, are to a significant degree incommensurable, having these starkly contrasting metaphors ready at hand helps to illuminate that. Now, since McGilchrist's primary intent here is to illustrate this contrast, the precise definitions of terms like "machine" and "life" are in some sense actually secondary considerations. Again, it is the existence of two fundamentally different, phenomenologically opposed "ways of attending" that he is describing. So if we get hung up on the terms we will miss the essential point. The comparison between metaphor and phenomenology becomes even more clear when in a separate interview he said: "The organism model can embrace the mechanism, but the mechanism model cannot embrace the organism."
Michael Levin, meanwhile, is more concerned with the terminological particularities as these apply to his research into embodied cognition. It's apparent that he would prefer to either use different metaphors when drawing out the contrast between lateralized phenomenologies, to avoid any conceptual confusion and equivocation, or better still, simply refrain from using figurative language to the extent possible and stick with the technical jargon of neurology and the phenomenology of lateralization. McGilchrist has no such misgivings. In the end, I think the combination of having both of these thinkers articulating the same situation, but from different angles or different levels of analysis, is to the benefit of all of us.
The hierarchical structure of these metaphors suggests that we can move from discrete categories of organism/mechanism, thinking/doing, and mind/matter, present on the first level, to the unification of these dynamics by ascending to the next level up, where such categories cannot be reduced one to the other. This structure further suggests that the "ordering principle" we keep "bumping up against" exists at the third level of integration that is still higher. The apparent conceptual difficulty we encounter here may be a consequence of our asymmetric faculty of analysis, which can more easily conceptually divide the levels below us, than synthesize and conceptually unite them into a "new gestalt" above us.
In this recent conversation Levin seems to have found a way to explain the metaphor in such a way that salvages its utility from an engineering perspective, while situating it within the purview of the hemisphere hypothesis and it's differing modes of attention. Shakespeare advises, "there is nothing either good or bad but thinking makes it so". Likewise, we might say that for Levin there are neither 'machines' nor 'organisms' as categories, but it is the mode of attention we use that makes them so. But this doesn't fully meet the 'value realism' of McGilchrist or Stein, who would say that attention doesn't "make it so" - that's the relativism of postmodernism. Instead, our attention "discloses the world", which is why one mode of attention is more veridical than the other. Nonetheless, this does seem to be some progress from Levin. The question is: Will he next incorporate an awareness of the phenomenological asymmetry between these coinciding 'frames' he has described? If he does, then his view would be nearly indistinguishable from that of McGilchrist.
Michael Levin: "If we think that machines and organisms are exclusive categories, we can get ourselves into trouble. I think that very simple mechanisms, in their own simplified way, exhibit an ability to do more things than will be apparent to us if we only use an algorithmic [computational] lens on them. For example, it's perfectly fine if your orthopedic surgeon wants to see you as a machine. But if your psychotherapist thinks you're a simple machine, that's no good. So there are these different lenses that you can take on different things. For some things, aspects of the machine metaphor are useful, and for other things, it will not capture the whole thing. But what we can't say is whether something really is a machine or really is not a machine.
These metaphors are 'frames' [perspectives] that we take on, and the beauty of it is that in the empirical testing we can compare. You bring your metaphor, and I bring mine, and we say "What does this help you do? Did you make xenobots, did you make anthrobots, did you make some sort of regenerative intervention?" "Well no, because I was using a bottom-up machine metaphor where molecular rules percolate up to complexity." Or "Well yes, I did because I was using a top-down [agential] metaphor where I thought the cells actually have the ability to solve certain problems, and I've manipulated them to solve those problems in a different way." So there it is. That's what I think about these metaphors."
I'm really glad to see some of the leading figures take on a more "top down" approach that is able to accomodate a few of the main themes within McGilchrist's work, such as hierarchy, asymmetry, and Gestalt. It's now very possible to argue for a qualitative asymmetry between the phenomenology of the hemispheres using the tools and methods available. But an unbridgeable gulf appears to remain between the quantities of science and the qualities of phenomenology. Leibniz's two realms still 'interpenetrate without interference'. What we know of the brain is that it appears to be a naturally evolved, asymmetric coincidentia oppositorum. And it underwrites some version of Marcel Kinsbourne's opponent process theory. The RH has greater access to ontological primitives (presencing to reality) than the LH, which by comparison appears to struggle to penetrate beyond the surface. Given any two neuroscientific models, one opaque and the other translucent, per McGilchrist, the latter one will be more veridical. Furthermore, it should be able to account for the former, whereas the former would not be able to account for the latter. Most of the premises underwriting the foregoing have already been described in clinical detail by McGilchrist. What would it mean to have a translucent model of neuroscience? Well, it probably wouldn't be computational, strictly speaking.
Further implications of opponent processing... The biosemiotician Wendy Wheeler had a phrase, “expecting the earth”, which alludes to Rosen’s “anticipatory system”. She was very keen on the difference between nominalism and realism. What is the anticipatory system anticipating? A real feature, or a feature that may be latent within the adjacent possible. Stu Kauffman noted the possibility of perceiving “wholes” (Kantian wholes). This is not unlike Gestalt perception. Gestalt perception is also hierarchical in the sense that it sees a whole “over and above” the parts. And so, if for example we can perceive a Gestalt before we infer the lower level elements required for its actualization, this may allow us to anticipate/ infer/ imagine/ predict a situation before it is logically/ computationally realized, thus drawing us toward an adjacent possible configuration before it is actualized. Stu referenced the LiOH filters jerry-rigged on the Apollo 13 mission as a possible example of this.
One key to this may be the nature of, and perception of, the “real” as opposed to the nominal (or non-Boolean as opposed to Boolean logic). Gödel’s incompleteness argument suggests that the adjacent possible cannot be completely represented. So computational systems that use logic premised on formal “completeness” are blind and delusional to the existence of such Gestalten or Kantian wholes. To overcome this limitation and perceive a new Gestalt that is latent within the adjacent possible, our system has to escape this logic trap. This may be the possibility of non-representational 4E knowledge. As we discussed, McGilchrist suggested (via Marcel Kinsbourne) that brain lateralization is the biological instantiation of opponent process theory, and by further implication, that it opposes representational processes (Friston’s active inference formalization) with non-representational (4E) processes in a complementary fashion. Each approach is an inversion of the other, with theoretically asymmetric capacities for Gestalt perception. And each of these “ways of attending” typically lateralize within the brain, a feature which has been assiduously conserved across evolutionary history.
Relevance realization seems to involve a (phenomenally salient) inversion of this sort. McGilchrist noted "We don't have values because we are alive, but life is necessary because there are values." Who was it who said that life is a necessary phase transition in the universe? This might be essentially the same insight. Perhaps the possibility of relevance realization (as well as telic agency) lies within these non-representational 4E cognitive processes which are capable of anticipating a Gestalt that lies beyond the limits of the paradigm of computationalism.
There's an argument against strong computationalism as a metaphysical position. Strong computationalism believes that all phenomena, and nature, can be reduced to processes of computation. But, as one objection goes, there may be a whole range of phenomena that are non-computable. If active inference is a computational framework for action and perception, then it may exclude certain aspects of a Gestalt that it cannot represent. And so, what may need to be opposed within an organism isn't necessarily two different processes, each of which is based upon a computational framework (computational vs. computational), but rather two different processes, one of which may be more akin to computationalism, and another which may substantially depart from this in its mode of perception/ attention (computational vs. non-computational). This sort of contrast is also implicit within McGilchrist’s approach to opponent processing.
Back to the lecture however, another notable feature of it was the heartfelt praise given from an audience member at the conclusion:
Mark Solms recently shared a paper online titled "Vascular Underpinnings of Cerebral Lateralisation in the Neonate" which may be interesting for those who like to get into the weeds a bit more. Solms introduced it with the teaser "It seems that few people are still interested in the origin of cerebral asymmetry, but it has continued to puzzle me since the 1980s. Herewith, possibly, the final piece of the puzzle." I appreciate the use of hyperbole to encourage greater engagement with a paper and research topic, but by no means is this the final piece of the puzzle. Nonetheless, there's some very interesting content (my emphasis):
"The cerebral hemispheres have... been shown to be asymmetric not only in function but also in morphology and cerebral perfusion. ...Neonatal arterial asymmetries are meaningfully related to future manual preference and therefore to cerebral dominance for language and practic functions. From a functional point of view, the direction of this asymmetry potentially accommodates greater perfusion demands in the hemisphere dominant for language and manual dexterity. ...The present findings do not exclude the possibility of a top-down, possibly demand-driven, neurodevelopmental process, in which greater left hemispheric resource utilisation culminates in commensurate compensatory changes in vascular supply."
And this, to my understanding, is where the relevance of McGilchrist's work comes in. A substantial portion of his thesis is devoted to exploring what exactly that top-down process might be, and asking the question "What is driving it all?" Or as Matt Segall recently phrased it: "Why is it that the world would give rise to a divided brain in this way?" The Matter with Things presents a “recapitulation theory” of its own; biology recapitulates metaphysics recapitulates biology.

However direct observation that would allow one to make a connection between behavior and the underlying neurological structures, can be inconveniently difficult to demonstrate. Hemisphere asymmetries are hidden behind an ostensibly symmetrical skull. So to help make functional biological asymmetries a more salient subject it might be helpful to point to the wide variety of other biological structures that also display asymmetry. One can point to lobsters, eusocial pistol shrimp, odobenocetops, sperm whale, and some owls.
Chirality, at both cosmic and cognitive levels
Lee Smolin is perhaps McGilchrist's single most cited (living) physicist, particularly concerning the nature of time. In this recent interview he dropped the highly provocative statement "Space doesn't exist, time exists, and is fundamental. And space and space-time emerge from the fundamental world." There's a lot of context surrounding that, but the importance of time for Smolin is clear, and shapes his entire approach. It's far from the only feature of his thought that resonates with McGilchrist. As their discussion continued, Peter Wojt's recent paper concerning the chirality of the universe was brought up. Smolin remarked "We want to understand why our world is chiral. I don't know why the world is chiral, but I think it's very non-trivial." Incidentally, we also don't fully understand why the brain exhibits chirality at the anatomical level, and yet it clearly does.
From the abstract of Michael Levin's article "Left–right asymmetry in embryonic development: a comprehensive review" we read: "Embryonic morphogenesis occurs along three orthogonal axes. While the patterning of the anterior–posterior and dorsal–ventral axes has been increasingly well characterized, the left–right (LR) axis has only recently begun to be understood at the molecular level. The mechanisms which ensure invariant LR asymmetry of the heart, viscera, and brain represent a thread connecting biomolecular chirality to human cognition, along the way involving fundamental aspects of cell biology, biophysics, and evolutionary biology. An understanding of LR asymmetry is important not only for basic science, but also for the biomedicine of a wide range of birth defects and human genetic syndromes." An earlier paper has the more fantastic sounding subtitle: "Toward a chiral psychology of cognition", which could easily serve as a succinct description of the hemisphere hypothesis. The hemisphere hypothesis is often associated with duality, but it is far more accurate to say it is about a kind of axiological or qualitative chirality.
Darwin College Lecture
McGilchrist: "Even if we were, by a massive effort and a massive stroke of fortune, enabled to prevent any further loss of the world's forests, reverse the pollution of the oceans, reverse the decline of species, and similarly tackle the other aspects of the metacrisis I have mentioned, this would be in vain if it simply meant that we did not change our hearts and minds. For we would still be the same hubristic, entitled, resentful, power hungry animals that we have become...
So my recommendations might be quite simple. Begin by cultivating a sense of awe and wonder rather than clever knowingness about the extraordinary complex and beautiful cosmos, which it is a pure gift that we have been given a life in. Think about what we're to do with it. And in order to do that well, to have compassion to others and to all the living world, not a sense of aggressive embattlement against forces that we quite probably misunderstand, and to begin to adopt a sense of the little that we can know. In other words a kind of, not 'willing ignorance', but the beginnings of 'true knowing', which is when we recognize how little that we know. That is the first step towards true knowledge. For this to happen we need to understand ourselves anew. Gnothi seauton. Know thyself. We need every insight we can get into what we're doing to ourselves, to life itself, and to our inexpressibly beautiful and complex world. I hope I may have here offered one such insight, however small. The work is great, but we are capable of greater things than we know." https://youtu.be/AuQ4Hi7YdgU?t=3434
Joint agent-environment systems
It may help to view McGilchrist as providing an alternative way to describe joint agent-environment systems. It's been remarked that, fundamentally, an agent and its environment are not fully separable. There's a coupling between them, a common phenotypic space that they share. And over time they tend to synchronize. This convergence emerges as the agent and environment ‘get to know each other’. How do we understand this ‘fit’ or 'attunement' wherein 'appropriate action' is being in tune with our environment? We are in a 'dialectic' with the world around us. And it is the nature of this dialogue (or dance) that determines which hemisphere will dominate at any moment. Typically we might ask "What kind of stressors does the agent need to respond to?" McGilchrist would add to that the question "What kind of values does the agent need to respond to?" The answer to those questions determines which mode of attention is best suited to the context. Today we are in dialogue with an increasingly artificially controlled environment, and we have been provided numerous tools that predispose us to a sort of manipulative form of engagement with that environment. All of this tends to reinforce the use of one hemisphere over the other in a kind of positive feedback loop, obscuring a more global and values-based form of engagement.
Getting from a "picture of the whole contextual world" to a "linguistic equivalent" involves a process of model building, of taking the "terrain" and simplifying it in various ways to produce a "map". This process was described by Jonathan Rowson as the "McGilchrist Manoeuvre". We analyze the whole by breaking it up and constructing an artificial model, an aid to mental and linguistic manipulation. Then we reintegrate this model with the terrain, such that we gain a deeper understanding of the world by 'seeing through' the linguistic model that was thus produced. The two then work together in a cyclic pattern of fragmentation and reintegration that promotes the dialectical synchronization between agent and environment. ...Unless or until we spin off into a positive feedback loop from which we don't escape. Which is of course the challenge today. So there are many dances, many complementary oppositions, in play: agent-environment, map-terrain, emissary-master, and so on. These are all, in a sense, one single process that is merely viewed from different perspectives. And that underscores how important our awareness of this may be.
"Holding power to account" can be viewed in these terms as well. It is simple in theory, but seems to be harder in practice. An 'opponent process' theory for 'joint agent-environment systems' might tell us that power dynamics play out among agents, but if we view the entire agent-environment system as a whole, then the nihilism of zero sum thinking becomes apparent. We can oppose the game theoretic approach of zero sum competition among agents with the positive sum gestalt perception of the entire agent-environment system. These two opposing views are in many ways inequivalent. Holding power to account means exposing the former as an incomplete aspect of the latter. It's the difference between a runaway positive feedback loop and a balancing negative feedback loop. Currently our counter-balancing forces are too weak and we are spinning out of alignment. We need a better understanding of what healthy opposition really is, and why we need it, if we are to avoid the "great filter".
Why is it good? He appears to suggest it's just a self evident precondition, a foundational axiom. However what he takes as his starting point is for some philosophers the end point of a deeper look into the foundations of ethics. He may be right, but not for the reasons he thinks. Notably for McGilchrist, there is a vertical aspect (some may say a 'nested' aspect) to value, morality, and all axiological considerations. In his short article on Scheler we read that 'sinnliche Werte' (values of the senses) are below 'Lebenswerte' (values of life or vitality) which are below the 'geistige Werte', (values of the intellect or spirit) which are below 'das Heilige' (the holy). So for McGilchrist the "well-being of conscious creatures" may be seen to correspond with Lebenswerte. Thus they are in some sense more important than our immediate gratification (and here he and Harris might agree), but less important than spiritual and holy values. And those latter values are likely unintelligible to Harris.
(This vertical aspect, this asymmetry or inequivalence, is also what frequently gets McGilchrist into trouble with some of his critics. Johnathan Cobb wrote "Go fuck yourself Iain" after describing, in his words, "McGilchrist's disgusting ableism toward autistic people". This seems to confabulate a number of different things, but I think it illustrates both the extreme confusion within contemporary society concerning how we understand and relate to axiological matters, and why some people would rather avoid the topic altogether. One might say it is a feature of Harris' framework for morality that it is not as vulnerable to this same kind of criticism. At least not nearly to the same degree that McGilchrist is vulnerable.)
So to recap, Harris and McGilchrist both agree that morality is foundational. As others have surmised, it's impossible to have any observation that is totally value-free. However Harris' foundations are his particular conception of what "natural phenomena" are, whereas McGilchrist's foundations are his conception of what "ontological primitives" are. So they have very different ideas concerning those "foundations". For more context, Harris wrote in his article:
Harris therefore reaches his "core claim that moral truths exist". What's more, he's "claiming that there must be frontiers of human well-being that await our discovery". Why does he focus so much on a scientific explanation for morality? It follows from his earlier work. Harris wrote:
Harris now has what he wants - a scientific justification that moral pathologies (and in particular Islamic fundamentalism) are indisputably wrong. He could have titled his book "The Health Landscape" no one would've objected to that, and it would've been a better fit for his definition of morality as well-being. Thomas Nagel had some pointed criticism that McGilchrist might assent to as well:
The case for moral truth, as he recognizes, has to come from within morality, as the case for scientific truth has to come from within science, and the case for mathematical truth from within mathematics. The true culprit behind contemporary professions of moral skepticism is the confused belief that the ground of moral truth must be found in something other than moral values. ...Some things are just true; nothing else makes them true. Moral skepticism is caused by the currently fashionable but unargued assumption that only certain kinds of things, such as physical facts, can be "just true" and that value judgments such as "happiness is better than misery" are not among them. And that assumption in turn leads to the conclusion that a value judgment could be true only if it were made true by something like a physical fact. That, of course, is nonsense."
McGilchrist: "Oh yes, I've worked with EMDR therapists.
Pringle: "So for the audience, roughly speaking, if you have trauma or PTSD, you can do eye movement back and forth (there's more to it than this obviously). You do a sort of controlled saccadic eye movement, and there's ways to do it with your body as well while you're sort of reliving and processing the trauma that's giving you PTSD. Empirically, there's a lot of people that absolutely swear by it, and it's gotten a lot of traction. I can't help but wonder if it involves some sort of visual and spatial inter-hemispheric processing as a result of going through the hemifields back and forth, and if that's somehow 'lubricating' a kind of interaction to deal with what might be a discordance between the hemispheres on the actual traumatic event. Do you have any thoughts on that?
McGilchrist: "I certainly do. As I say, I have myself had patients to whom I've recommended EMDR, and they've done very well with it. Interestingly Jaak Panksepp, who unfortunately died a couple of years ago but was the world's greatest authority on affective neuroscience, himself had an experience after which he had EMDR. And he said it worked wonderfully well on him. What we do know is that there is a 'switch' in the tegmentum of the midbrain, which is not the middle of the brain but is the name for the top part of the brainstem. On a millisecond to millisecond level it is sending stimuli to one or the other hemisphere. I think that what happens in trauma is that the right hemisphere is very powerfully 'fired up' and eventually becomes stuck. And there are only two alternatives for it, and these can be seen in following a patient with PTSD. Often there's an early phase of dysfunction because of, as it were, unfettered emotional release, and then it can be followed by a period of cold detachment in which, because it's too painful, all affect is cut off.
Now these are both extreme positions, and for health one doesn't want either to be swamped by unhelpful emotions or to be cut off from emotion. This eye movement process is a bit like kicking the washing machine. You know, if it doesn't go you give it a boot and it's working again. We don't really know what happened there, but I think that it was released, it was no longer stuck. So the PTSD patient is 'stuck', as it were, with a dysfunctional relationship with the right hemisphere, and because of this need to keep going backwards and forwards with the hemispheric switch it is 'freeing it up' again. That's all I can say about it. And that's a speculation, but all we have at the moment are speculations, and I think it's as good a speculation as any." https://youtu.be/3Jik-_E0FfY?t=2113
Incidentally, Dietrich Bonhoeffer once described life to his friends as a polyphonic composition, with God's love as the cantus firmus and our life stories as the counter-melody. All together they make up harmonies and the beauty of a musical piece... There were a few other interesting portions of the interview. Particularly when he talked about the contemporary discourse on social identity, and what he called the "Trump Effect", which he described as a political paradox in which something like the inordinate pursuit of equality, at the expense other values such as justice, counterintuitively results in effects that nobody wants (somewhat like enantiodromia).
Kauffman's emphasis on wholes, downward causation, and our participatory, co-creative role in the universe are all themes that should be very familiar to readers of McGilchrist. In an interview with Jim Rutt, Kauffman discussed a few of his more recent papers with co-author Andrea Roli. In the selections below, he provides a more detailed description of "Kantian wholes" and how a "third transition in science" has implications for the global economy.
The first transition in science is the Newtonian paradigm, quantum mechanics is the second. All of science, essentially all of physical science is a Newtonian paradigm. But the evolution of the biosphere is beyond the Newtonian paradigm. We can’t use any mathematics based on set theory to deduce what the biosphere is going to become. The way that the Kantian whole gets to come to exist, and the ever new uses of the parts that sustain the whole, cannot be said ahead of time. It’s strong emergence. It cannot be deduced.
This is radical creativity in the universe, and it means so many things. In the Jewish Bible there’s two readings of the first sentence: God “created” heaven and earth and gave Adam mastery, or God “creates”. Well, if God creates, he doesn’t give man dominion over what hasn’t been created before. That’s Western science - science is to have dominion, command and control over nature. If Andrea and I are right, we don’t have any dominion over the ongoing biosphere. We have no idea what it’s going to do. We become participants with the rest of nature. I think it’s a profound transition. And what does it mean for science? I want to ask: How does the evolving biosphere keep creating novel possible ways of things getting to exist together? It’s been doing it for four billion years.
This inevitably invites questions. Kauffman's initial description is “In an organized being, parts exist for and by means of the whole.” To which he adds "Kantian Wholes are a special class of dynamical physical systems." For Kauffman, this is just a necessary, but not sufficient, condition for life. What then might be sufficient? Kauffman tentatively proposes: "This newly recognized union of four closures: Kantian Whole, Catalytic Closure, Constraint Closure, and Spatial Closure is Bergson’s mysterious élan vital... Life arises as an expected phase transition in the evolving universe." What I want to draw attention to here is that Kauffman is pointing us to a conceptual shift from parts to wholes. And although he didn't specifically say it, in connection with that shift we should begin to think of the right hemisphere, of integration, and of Gestalt perception. Recall that McGilchrist suggests we can view anything from the perspective of either hemisphere. So all things can be seen in two very different ways. This means that, viewed in one way, a body isn't a Kantian whole. We can certainly reduce everything to atoms. This is the standard eliminativist move of scientism, which by reducing everything to 'matter in motion' we are able to conclude that meaning, purpose, and value (and Kantian wholes) do not exist.
Viewed in another way, a body is a Kantian whole. In fact almost anything could be viewed as a Kantian whole, at least if we restrict the definition to the ambiguous "parts exist for and by means of the whole" without any of the later qualifications Kauffman added in his papers. But that said, if we compare a machine to an organism we do see some differences. How do we describe these differences? Again, there are two different approaches. The left hemisphere prefers definitions that provide us with a clear division line and mutually exclusive categories. But the right hemisphere recognizes that reality presents us with something more like a continuous spectrum, where there are things that are "more like" a Kantian whole and things that are "less like" one. A machine can be disassembled and left on the shop room floor, then reassembled a week later without too much harm. By comparison, on a hospital operating room table doctors generally have a shorter window in which to reassemble a body after removing critical parts from it, after which point irreparable harm may result.
Both Robert Rosen and Kauffman appear to be in broad agreement. Kauffman compares the Newtonian and quantum mechanics paradigms and concludes "it's the same thing". Rosen gets high praise from McGilchrist. Another outstanding theoretical biologist, but one who doesn't get the attention deserved, is Stanley Salthe. Arran Gare (a prodigious reader and writer himself) mentions Salthe in connection with Rosen in some of his papers and books, remarking on the similarity of their approach. Terrence Deacon, perhaps most similar to Kauffman, gets a mention in the interview with Jim Rutt as another well known theorist. These two are very good in interviews, but all four are singing the same convergent tune, with slight variations.
Robert Rosen believed that the computationalist perspective of the Church-Turing thesis was inadequate. He argued that life itself has to be understood as the product of an interacting system, rather than being the separable parts into which the organism can be broken down. Furthermore, his emphasis on how 'function is spread over the parts' suggests that our folk assumptions regarding 'system boundaries' are indeed illusory. This is also an implication of the 4E framework (embodied, embedded, enactive, and extended).
Living systems relate to their parts in a different way from machines. Robert Rosen noted that an organism differs from a machine in that it has causal closure of the functional components (not material parts) of the system. Function is distinct from, and irreducible to, the parts. It is "spread" over the parts of the system in a manner which does not map 1:1 onto those parts. Function is also contextual or situated. It is able to leverage physics, the nested systems of "enabling constraints" present in the world. Without seeing the entire integrated system (Kauffman's "Kantian whole"), the functional components are themselves meaningless.
Rosen noted that organisms work toward fulfilling their existential needs before these become a crisis, but their models are only as good as the information they are based upon, and so they are vulnerable to "quick" and "radical" changes (Rosen, 1980); “as a result, they are often incapable of dealing with or surviving change that is unprecedented. But, as long as environmental changes are slow enough and congruent with what the model entails, the system is robust and remains stable”. Today we know we are heading toward a future of radical, quick environmental changes, the effects of which could be devastating.
The process philosopher Whitehead believed that causal connection takes place, not in virtue of the cause, but of the effect, in other words that causality pulls us ever toward the future. As John Deely wrote "the future beckons the present", or as Rosen said, models pull "the future into the present". As the present begins to merge with the future, we see all the more clearly the possible effects of the actions we take today. The theoretical neuroscientist Karl Friston wrote that "beliefs about outcomes in the distal future influence beliefs about states in the proximal future and present. That these beliefs then drive policy selection suggests that, under the generalised free energy formulation, (beliefs about) the future can indeed cause the past." Life both predicts external causes of sensory states and causes the external causes of sensory states through action, in processes of active inference (Friston) or inferential entailment (Rosen).
Stanley Salthe wrote: "Final causes are informational constraints. And they may be viewed as teleological without confusion; an organism can be said to want to persist, and so, on the basis of both specification and scalar hierarchies can a population or ecosystem. ...the encompassing system constrains, regulates, controls and interprets the behaviors of those nested within it merely by forming the superstructure for their activities." (Development and Evolution, which includes outlines of these hierarchies) Similarly, Ulanowicz writes: "The direction in which a system is headed (its telos) is not only an integral element of its integrity, it also can impart a legitimacy to ethical considerations of how society should interact with the system." (Ecology, the Ascendant Perspective 125)
In “The System of Interpretance, Naturalizing Meaning as Finality”, Salthe writes: “Subsumption connects closely to finality. In a subsumptive hierarchy, lower integrative levels subsume all higher ones, while higher ones simultaneously contextualize (integrate) all the lower ones under their own rules. An organism, city, ecosystem, or storm system are good examples of integrated systems. In particular, the storm, by being embodied at no higher than the physico-chemical levels, is more vaguely embodied than are systems at higher integrative levels like organisms. Macroscopic particularity and precision increase as we ascend to higher integrative levels. ...Thus, we ourselves, materially, are states or configurations of lower level entities – cells, macromolecules, electrons, and so on. But these are not us. We are integrating them under our own organizational rules. In an internalist sense we could be said to be the integrative experience itself, in the process of intending/entraining/attending to that experience.” ...Note that our current situation today in regard to global health, depending as it does on our ability to integrate lower hierarchical levels, is marked by the general breakdown of these very processes.
Lovisa Sundin writes: “Any “system”, is simultaneously a part and a whole – equally dependent participants in a higher-order relation and self-contained entities themselves. We may dub a recognizably multi-leveled tendency “arborization”, and horizontal interaction across such systems “reticulation”. And so what crystallizes in this arborizing brew, when left to seethe, is an underwater coral reef of interlocking hierarchies, not entirely decomposable (but nearly so) and teeming with desire to self-complicate. ...The most important insight carried by hierarchy theory is that the continuum between simple systems and complex systems – between rocks and organisms – makes ontology applicable to them all.” You may recall that Arthur Koestler coined the term “holon” from the Greek “hol” meaning whole and “on” meaning part. A holon is something which is simultaneously a whole relative to its constituent parts, and a part relative to some larger whole.”
One thing I find fascinating is the discussion on teleology that writers like Stanley Salthe, John Deely, Robert Rosen, Peter Corning, Arran Gare, Terrence Deacon, and Robert Ulanowicz turn to. "Inevitably," Ulanowicz writes, "the rehabilitation of formal, and especially final, causalities will elicit strong, but misdirected criticism from those who abhor teleology in biology." Nonetheless, final causality may be critical to addressing societal dynamics and our relationship with the environment. The ability of hierarchical systems in ecological relationships to entrain lower levels illustrates a kind of final causality that we need to address, for example in the context of climate change policies.
If we understand these dynamics it becomes more clear in which ways our actions, at all scales, either support or undermine other processes within our environment. With that understanding we can be better prepared to chart a course into the future. The incorporation of a living cosmology, where organically developing processes are fundamental, is a radical but necessary departure from our current understanding. Ulanowicz writes that if one wishes to understand living systems "one must abandon the assumptions of closure, determinism, universality, reversibility and atomism and replace them by the ideas of openness, contingency, granularity, historicity and organicism, respectively." There's a lot of potential in that replacement. What if we understood the contingency of economics? Or the organic nature of society? How would this shape policy, public planning, and research priorities? McGilchrist doesn't mention Ulanowicz, but the contrast here appears to correlate to the contrast between the hemispheres.
Jaeger et al. write: "Based on his categorical distinction between simple and complex systems, Rosen derives his most famous conjecture: he shows, in a mathematically rigorous manner, that only simple systems can be captured completely by analytical (algorithmic) models, while any characterization of complex systems in terms of computation must necessarily remain incomplete... Rosen’s, like ours, is an incompleteness argument analogous to Gödel’s proof in mathematics [which states that every sufficiently complicated formal system remains incomplete, because there will always be valid propositions that are true but cannot be proven within the existing formalism]. It may well be possible to approximate aspects of biological organization through algorithmic simulation, but it will never capture the full range of dynamic behaviors or the evolutionary potential of a living system completely [natural agency and cognition cannot be grounded wholly in formal problem solving, or any other form of algorithmic computation]. If true, this implies that the strong Church-Turing conjecture — that all physical processes in nature must be computable — is false, since biological organization provides a clear counterexample of a physical process that cannot be captured fully by computation."
In short, algorithmic computational simulations will never capture complex systems. The deeper point, per Gödel, is that nothing can. So if we are serious about creating "artificial life" replete with all the processes outlined in this and other papers on this subject, we need to adopt a different approach to design. Less focus on a deterministic design philosophy, and instead a relational design approach that appreciates how embodied relational processes function within naturally evolved cognitive systems. Because not all analog phenomena can be reduced to digital quantification. And function does not map 1:1 onto the parts of a system. Rather, it is "spread" over them and "spills" into the surrounding environment. It is contextual or situated, and able to leverage physics, the nested systems of "enabling constraints" present in the world. The functional components are themselves incoherent without the ability to infer (or anticipate) aspects of a much larger integrated system whose existence can never be exhaustively stated. You can see how Kauffman's notion of "Kantian wholes" is useful here as well.
Surrogate predators
The context of early human evolution was a far more precarious existence. It was a world of megafauna, literal giants. In the dialectical dance between man and nature, we were not the main characters. This, Ehrenreich suggests, provided us with a palpable sense of humility, which of all virtues mitigates the excesses of the left hemisphere, supplying the negative feedback we need. Today we find ourselves 'the victim of our own success'. Dual inheritance theory may explain megafauna overkill, and both of these led to the ecological release of humans and the tendency toward phenomenological inversion that McGilchrist describes. So in short, why should the emissary have ever had the capacity to usurp the master? An evolutionary response to McGilchrist's implicit question is that it was ultimately only a lack of means and opportunity that held it in check. But after it was liberated, and its power and control extended (and extends still further today), its grasp tightened. With our tools in hand and our predators vanquished, we have allowed ourselves to fall under its spell, and we've forgotten the Faustian bargain that always attends to acts of hubris and self deception. Many writers have explored the generative tension between constraint and possibility. For example, and in connection with the current topic, Arran Gare wrote:
"Nothing that is good can come into the world without directly producing a corresponding evil" Jung wrote in 1933, adding several decades later in 1959 that "we are the origin of all coming evil". Heinlein concurred, “By the data to date, there is only one animal in the galaxy dangerous to man – man himself. So he must supply his own indispensable competition. He has no enemy to help him.” What can restrain our ambition and restore a sense of humility, this virtue we have neglected at no small cost? Meditation, mythos, memento mori, megafauna, or...? Daniel Schmachtenberger described the possible emergence of the first wisdom traditions as an attempt to bind our hubristic excesses in light of this "first anthropogenic crisis", the extinction of megafauna. Our metastable psychology guarantees no final resolution to this generative tension, but it does make our keen awareness of it all the more important, especially given the reification of our “maps”, which simulate the world in ever greater detail and trap us in labyrinthine positive feedback loops, replete with addictive supernormal stimuli, and from which escape seems all but inconceivable. As Zizek noted, even the ‘end of the world’ can seem more likely than the end of the powerful systems we've created that now entrain us.
“To everything there is a season… A time to get, and a time to lose; a time to keep, and a time to cast away.” But all the LH wants is to get and keep. And its outsized influence has allowed us to create a world in which we think this is an option. For some, this may be truer than for others, but we all share a common fate. We need continual reminders that none of these things will last, that there are more important considerations to which we must attend, and that the animate world of the RH relates to time, things, and experiences in a way (through a set of values and mode of perception) that is for the most part incoherent to the LH. We live two intimately intersecting lives in parallel. One sees the rhythms and relations, and the other manipulations (without intrinsic meaning). Change need not be unreasonably feared, things need not be hoarded, and experiences can be fully inhabited. Nothing can be held onto forever, despite the best attempts of the grasping left hemisphere to do so. We hoard belongings, memories, money, knowledge, and chase after new highs and experiences, ticking them off a bucket list. “He (or she) who dies with the most wins.” This is about power, control, greed, hubris, and projecting our legacy beyond the grave.
But time, the universal solvent, washes away all trace of our LH representations, leaving behind only the RH aspects of who we are that have nothing to do with conventional notions of identity. What is your “original face”? “When buddhas don’t appear and their followers are gone, the wisdom of awakening bursts forth by itself," Nagarjuna tells us. If we can let go of transient things, it may be easier to live the life we are given. Letting go implies the choice is ours. But history tells us that this wasn't always the case, and certainly it wasn't before our ecological release. There's a sort of paradox here. We are not free to be completely unconstrained (compare with the paradox of tolerance). In other words, constraint is not a matter of choice if we want to preserve the freedom to choose. A possibly controversial conclusion is that insofar as we are reliably good, virtuous, and cooperative, it is not merely because we want to be, but because, as Hobbes and many contemporary evolutionary psychologists might argue, we have to be. And if that is the case, then our restraints and frictioins cannot be internally motivated alone; there must be an external environmental component as well.
But we've let the genie out of the bottle, and cannot return to our prehistoric cradle. If Gare is right, and further advances in constraint are required, then in light
of the hemisphere hypothesis, what if anything can we say about the place of external constraint? Many have looked at self-constraint, but who is looking at the constraints we have little to no power and control over? From environmental constraints of age, infirmity, and death, to lack of food and shelter, to loneliness and depression, and all physical, emotional, and mental limitations, there is a spectrum of these. They are simultaneously our friend and foe, and come uninvited. We must look to these today and not ignore them, not necessarily with the aim to eliminate them (though many certainly should be mitigated), but to see these uncelebrated burdens as the "thorn in our flesh" that leave us "utterly undone" like the Biblical Job. They are the safeguards of our humility and appreciation of life in place of the predators we have lost, and like those predators, eventually they catch us. Donna Haraway famously wrote "we have never been human". We have never escaped limitation; the conceit is that somehow we have. We cannot give up an abstract freedom that we never had, but we can give up the deluded belief that we, or anyone else, ever had it to begin with.
