Philosophical Speculations

Regarding the anecdote about the two researchers, I think you will agree that it points to the brain and its neural ramifications in the body (together, the head organization) being the physical image of the activity of perception-ideation, without including feeling and will in the picture. Only the thinking aspect of the conscious ordinary experience of thinking-feeling-will is included, since feeling and will arise in the soul independent of the head organization. This is important because, as I described here, such amalgam - the modern habit by which we are led to conceive all soul activity as nerve activity - leads us astray in our attempts to gain holistic understanding of man.

Now one could say: “Didn’t you just insist that nerves are the seat of metabolic and rhythmic activity too?” Yes I did. The subtlety that clarify why this isn’t a contradiction is this: each of the three parts of the human organization (head, rhythmic system, and metabolism + limbs) has its own function proper (thinking, feeling, and will respectively). In this differentiation we can identify the independent origin of the three activities of the soul. However, they are also totally interconnected with each other, and with the subtle bodies that cooperate to activate the functions. Thus we can say that the head organization - as described in the anecdote - is the only proper seat of perceptual-ideational processes, but we can also say that the head organization is a locus of will and rhythmic activities too. The spread-out nervous system (a primitive brain) happens to be primarily the physical image of the latter activities, while the brain (a more evolved spinal cord) is an image of the former one (ideation). So the brain, yes, it lets us infer the imaginative life of the thinking soul, but not the nervous system. The brain, in its salty parts, is indeed the physical image of ideation, because those few crystallized, solid parts are precisely ‘the mirror’ of living thinking. They are what grants us waking consciousness. It’s only because of those little earthly calcifications that we are awake in the outer world, by reflecting the living ideas in it. But the spinal cord and rest of the nervous system don’t do that. Their proper function (perception) is only grasped imaginatively, as we said. This also means that what they are an image of, physically, is their secondary, metabolic-rhythmic activity, as I tried to briefly convey in the last part of this post.

Ashvin wrote: I am now not sure what you imply when saying observable neural activity is "metabolic" instead of "perceptual". I have previously taken that to mean that this activity has little do with human sensory perceptions and the corresponding life of thinking, and therefore observing that activity does not provide any insight into 'nervous function proper' as the basis of our representational thought life. Is that accurate or are you implying something else?

Yes, that's accurate. I may be wrong, but this is my current understanding. The physically observable activity of the nerves has little to do with perception and ideation.


A relevant lecture: GA 212/2 - Apr 30, 1922

Thanks for elaborating on that. We are certainly on the same page that the deeper life of feeling and will (beyond our mental pictures of those spectrums) are not explicitly reflected in the brain and nervous system, and that our intuitive state always transforms as something whole, i.e., there is no state of 'pure nervous activity' without rhythmic and metabolic activity, just as there is no mental picturing without feeling and will implicated in the meaning of those pictures. For example, if I simply imagine a triangle, my intent modulates not only the nerves in the brain, but also, to some extent, my breathing, blood circulation, and metabolism.

On the other hand, I am still quite unsure about all of the remarks in bold. For example, if I close my eyes, focus intensely, and push through tunnels of mental images of peaceful natural landscapes, I can modulate the heart organ and blood flow through the nervous system, which will feed back certain conscious sensations. These are nerves that extend beyond the brain and head region into the lower body. All of that could be physically detected as well. So I'm not sure, phenomenologically speaking, how we could say this nervous activity has little to do with the life of perception and ideation.

But perhaps you are still speaking about something different?

Regarding the confidence in the spreading of proper conceptual foundations in education, I agree with you. It’s difficult to imagine how it could work out in real life without causing confusion, mocking and rejection. In what I wrote I was conveying what I understand as Steiner’s intention, or at least general purpose, rather than my convictions. In defense of such purposes however, we can observe that Waldorf school is a concrete example of an education that (when conducted properly) doesn’t put a spanner in the works of possible future spiritual-scientific learning, without imposing it at the same time. And since it is clear that young people need not only a holistic primary school, but as they grow, also a scientific and/or artistic higher education before they can possibly begin any esoteric schooling (for age reasons), the question arises, from an anthroposophical perspective, of how to offer a higher education that is not too damaging and dogmatic in its conceptual approaches. I believe Steiner in his ideal line of work was planning to develop his educational initiatives beyond the education of the child, to extend the initiatives to higher studies. Personally, I don’t have the confidence you mention. I would have no idea where to begin. But Steiner certainly did, and I believe we should remain somewhat optimistic when contemplating the possibilities for Anthroposophy to offer less materialistic conceptual foundations to the uninitiated youth, even in our degenerating world.

Right, that makes sense to me. I suppose that the key goal of a Waldorf education is to instill the optimal soul and intellectual qualities, through a curriculum based on a deep spiritual understanding of the developmental phases of early life, so that the soul remains mostly receptive to the perspective shift in later life, no matter what field of inquiry it ends up working in and contemplating. I can see how a similar educational initiative could be extended to adolescence and early adulthood.

It’s not only that our intuitive state always transforms as something whole, but also that each of the three soul activities independently gives origin to each of the three bodily functions, or systems: head, rhythmic system and metabolism-limbs. As I tried to highlight, that’s an essential point.

Steiner wrote:We really would be separated in spirit and soul from one another if, when we meet, all our feeling and willing developed within our nerves, enclosing us completely within our skin. Modern people have that feeling, and the increasingly antisocial condition prevalent in modern Europe is a true representative of that feeling. (GA 301/2)

When I say that our ordinary conscious experience of intuitive steering and the corresponding imaginative flow is not condensed almost exactly into the structure and activity of the nervous system, I mean that, yes, feeling and will don't manifest in nerve function directly, but also - more importantly in this discussion - that in the physically observable spectrum the three functions take place one within the other, nevertheless, what is metabolic or rhythmic in nerves will always and only be the image of will activity or feeling activity respectively, not of ideation-perception.

Therefore, coming to your example (in blue), that's how I understand it. There is an intentional inner gesture that brings forth pictures of peaceful landscapes. That is, at the soul level, there is willed ideation and perception of thought pictures. As I see it, that such ideation generates muscle modulation and sensations through the nerves is not a phenomenological observation, but an abstraction based on natural scientific reasoning. You don’t have an experience that the path taken by your spiritual activity in the body goes through the nerves. Affirming that seems similar to what Steiner calls out here: “Look, for instance, at the effects of Herbartian psychology. It confines its attention exclusively to the process of representation, and regards feeling and willing merely as effects consequent on that process.“ (GA 21/7)

Steiner wrote:Only materialistic presupposition can relate the element of metabolism in the nerves with the process of ideation. Observation with its roots in reality reports quite differently. It is compelled to recognise that metabolism is present in the nerve to the extent that will is permeating it. (...) Neurology will never arrive at concepts that measure up to the facts, so long as it fails to see that the specifically neural activity of the nerves [that which correlates with representation and ideation] cannot possibly be an object of physiologically empirical observation. (GA 21/7)

What one really experiences is the intention to do the exercise, the beautiful mental pictures, and the pleasant feelings and pleasant bodily sensations, that measurements would probably correlate to muscle relaxation, including the heart muscle (similar to what happens in sleep). The tracing from soul activity to the organism could be described as follows. Your ego-astral organism decides to ideate the landscapes, minimizing connection with the sense organs at the same time (eyes closed). The conscious reflection of this activity takes place in the brain (mental pictures of landscapes). This process of conscious perception of the pictures is not traceable to physically observable neural activity, as we previously agreed. At the same time, as we also agreed, feeling and will are active. So, nervous activity proper (ideation and perception) takes place but is not measurable. At the same time, the feelings induced, or summoned, affect breathing - the rhythmic organization - hence blood oxygenation. In turn, blood feeds back rhythmically, up into the head and also down in the entire organism, creating the physical basis for a semi-conscious feeling of well-being and relaxation. Here, feeling and its independent action on breathing joins will and its independent action on metabolism. The will to execute the exercise eyes closed has the metabolic effect of slowing down the inflow of sense perceptions whose metabolic function is to (unconsciously) build the inner organs through the afferent nerves (anabolism, metabolic nerve function). As a consequence, catabolism (muscle activation, combustion) is also reduced, which the efferent nerves supersensibly perceive (in this, they operate in their proper capacity, parallel to their metabolic capacity). On the physical plane, they induce a reduced muscle activation (metabolic capacity of the efferent nerves) and on the non measurable plane, what they do is to testify to the reduced burning activity of all muscles (they perceive that metabolism).

Trying to bring together and understand Steiner’s perspective, this is more or less what I gather, and how I think he would treat your question. To summarize again, all begins with willed ideation, paralleled by semi-conscious feelings and unconscious will. All three activities independently descend in the three somatic functions. However, these functions, as they manifest physically, take place one into another within the organism, and can’t be neatly isolated. The feeling of well-being that you summon affects breathing, thereby blood oxygenation and flow, through the heart. The will that you form in your soul manifests as metabolism in the organism, in that the afferent nerves receive reduced sense perception/intake of cosmic forces, thus they slow down their organ-building activity. That is, anabolism slows down. Concomitantly, the efferent nerves meet the slower blood flow in the entire body, and adjust all muscle activity accordingly, including cardiac activity. Less is built up in the organs by the afferent nerves, and less is combusted in the efferent nerves and connected muscles as well. Everything slows down, coming closer to a sleeping state. Additionally, the efferent nerves take stock of the evolving state, in their connection with the muscles, as a token of the willed (but unconscious) metabolic modulation.

I don’t know exactly how the observable correlates of this exercise would look under measure instruments, but I think Steiner would say that what can be seen and measured in the efferent nerves is their metabolic action of regulating the pace of combustion, not their proper nervous function of perceiving the muscle activity.

Steiner wrote:The differentiation between sense and motor nerves is a most willing servant of materialism. It is a servant that could have arisen in materialistic science only because a cheap comparison could be found for it in modern times, namely, the telegraph. We telegraph from one station to another and then telegraph back. It is approximately a picture of the process of telegraphy that people use to describe how the sense and motor nerves communicate between the periphery and the central organ. Of course, this whole picture was possible only in an age like the nineteenth century, when telegraphy played such an important role. Had telegraphy not existed, perhaps people would not have formed that picture. Instead they might have developed a more natural view of the corresponding processes.

It may seem as though I want to trample all these theories into the ground simply for the sake of being radical. It is not that easy. I began to study nerves as a very young man, and it was very earthshaking for me when I noticed that this theory served materialism. It did this by transforming what is a direct influence of the will upon the metabolism into something merely physical, into an imagined physical strand of nerves carrying the will impulse from the central organ to the periphery of the human being to the muscles. People simply imposed material processes upon the human organism.

In an act of will, there is in truth a direct connection between the will impulse of the soul and some process in the metabolism. The nerve exists only to transmit the perception of this process. To the same extent, the nerve also exists to transmit the perception necessary when there is a relationship between the person’s feeling and a process expressed in circulation. That is always the case when we feel. Essentially, the basis is not some nerve process; it is a modification of our circulation. With any feeling, there is a process that does not exist in the metabolism, but in the rhythm of circulation. What happens in the blood, in the lymphatic system, or in the non-metabolic aspects of the exchange of oxygen (the exchange of oxygen is actually metabolic, and to that extent it is a part of the transfer of will)—to the extent that we are dealing with the rhythmic processes of breathing—belongs to feeling. All feeling is directly connected with the rhythmic processes. Again, the nerves exist only to directly perceive what occurs between the feeling in the soul and the rhythmic processes in the organism. Nerves are only organs of perception. (GA 301/2)

Above, you say "feeling and will don't manifest directly in the nerve function," but then you also imply that the observable activity of the nerves can only be the image of its metabolic (will) process, rather than ideation/perception. That is part of my confusion on this topic, which, again, could possibly stem from my lack of understanding of what you are expressing and how you are expressing it. Some of the discrepancy seems to be rooted in this quote from Steiner:

"Neurology will never arrive at concepts that measure up to the facts, so long as it fails to see that the specifically neural activity of the nerves cannot possibly be an object of physiologically empirical observation. Anatomy and Physiology must bring themselves to recognise that neural function can be located only by a method of exclusion. The activity of the nerves is precisely that in them which is not perceptible by the senses, though the fact that it must be there can be inferred from what is so perceptible, and so can the specific nature of their activity. The only way of representing neural function to ourselves is to see in it those material events, by means of which the purely psycho-spiritual reality of the living content of ideation is subdued and devitalised (herabgelähmt) to the lifeless representations and ideas we recognise as our ordinary consciousness. Unless this concept finds its way somehow into physiology, physiology can have no hope of explicating neural activity."

This is something we also consistently express with our phenomenological explorations. The activity of thinking can never be found contained within the receding mental pictures of that activity, which arise as reflections of the nervous system. The latter are the fully finished results of thinking, which cannot be combined with each other in such a way that builds an understanding of 'neural function', but still provide a basis to infer the activity of thinking and its specific nature (many of its characteristic dynamics). In other words, we should see in these receded pictures a testimony to a higher activity of thinking, which can only be known experientially (not by analytically observing, combining, modeling, etc., the pictures of nerves and their behaviors), and which becomes our ordinary conscious experience of ghostly, sequentialized mental images when formatted through the nervous system. In that sense, we can't know the function of the nervous system as a mediator unless we have some intimate experience with the higher life of thinking that is being mediated. How could we have any real understanding of this mediation if we don't even suspect at least two inner spectrums of experience which exist in some relation to one another? All the major theoretical problems arise when we try to understand bodily perceptions and their relations from entirely within the focal plane, i.e. within a single spectrum of inner experience. Then we are practically forced to move toward reductionist explanations, which then forever blind us to the deeper inner dynamics.

We should remember that Steiner consistently emphasizes how closely the physically observable nervous system is related to the life of perception and ideation (and in the previous quote, he makes it a point to say "whole" and "entire" nervous system), whereas the deeper life of feeling and willing has almost no similarity to what is physically observable. We experience a conscious waking state only through this nerve mediation, whereas inner experiences mediated through the rhythmic and metabolic systems normally drop us into dream life or unconscious sleep. That is a big part of the reason why the whole soul life is ascribed to the nervous system and all other bodily processes are imagined as mindless mechanisms. And this makes great sense when we realize that what is physically observable in our waking state is always our thinking process mediated by the nervous system. To experience the life of this thinking, we need to ascend to Imaginative cognition, and only then do we truly understand the 'proper function' of the nervous system.

So I don't think we agreed that "this process of conscious perception of the pictures is not traceable to physically observable neural activity". I thought we had agreed, as Steiner also consistently emphasizes, that this life of conscious perception and ideation can be traced with great precision to the brain's neural structure and activity. It also seems to me that this fact is beyond dispute on empirical grounds, as evidenced by research on the neural correlates of consciousness. Do you agree with that?

From your posts, I gather that you feel something fundamentally changes when we descend into the efferent-afferent nerves of the lower body, and the life of perception and ideation no longer correlates strongly with what we can observe happening there. It certainly seems that the sympathetic nervous system is associated with a deeper life of perception-ideation that is hardly conscious. We experience this as instinctive perceptions and reactions to aspects of our environment that don't require conscious reflection, like when a loud, unexpected noise makes us jump back. This deeper nervous system still reflects living imaginations which are normally 'drowned out' by the cerebral nervous system, through which we experience our ghostly mental pictures as fragmented extracts of the living imagination. From that perspective within the flow, our deeper imaginative life is felt like the wise realm of instinctive perception and action. On the bodily side, it is represented as the formative forces of growth in the organism. If that's what you are pointing toward, then I fully agree. Steiner expresses it as follows:

https://rsarchive.org/Lectures/GA055/En ... 25p02.html

"In the first instance, the sympathetic nervous system gives rise to the kind of sentient life just described. But a person's consciousness does not reach down far enough to experience the cosmic processes it mirrors. The surrounding cosmic world out of which the human being, as a living being, is created, mirrors itself in the sympathetic nervous system. There is in these nerves a dull inner life. If human beings could dive down consciously into the sympathetic nervous system, while the higher nervous system fell asleep, they would behold in a world of light the workings of the great cosmic laws.

Human beings once had a clairvoyant faculty that has been superseded. However, it can still be experienced, if through certain measures the function of the higher nervous system is suspended, setting free the lower consciousness. When that happens, the world is experienced through the lower nervous system in which the environment is mirrored in a special way. Certain lower animals still have this kind of consciousness. As explained, it is extremely dull, but provides a dim awareness of a far wider aspect of the world than the tiny section perceived by humans today.

At the time when evolution had reached the stage of the cosmos being mirrored in the sympathetic nervous system, another event occurred in human beings. The spinal cord was added to the sympathetic nervous system. The system of brain and spinal cord extended to the organs, through which contact was established with the outer world. Once their organisms had reached this stage, humans were no longer obliged to be merely a mirror for the primordial cosmic laws; the mirror image itself now entered into relationship with the environment. The incorporation of the higher nervous system in addition to the sympathetic nervous system denoted the transformation that had occurred in the astral body. Whereas formerly it participated dully in the life of the cosmos, it now contributed its own inner experiences.

Through the sympathetic nervous system, a being senses what takes place outside itself; through the higher nervous system, what takes place within itself. In individuals at the present stage of their evolution, the highest form of the nervous system is developed; it enables people to obtain from the highly structured astral body what is needed to formulate mental pictures of the outer world. Therefore, a person has lost the ability to experience the environment in the original dull pictures. Instead, individuals are aware of their inner life, and build within the inner self a new world of pictures on a higher level. This world of mental pictures mirrors, it is true, a much smaller section of the outer world, but does so much more clearly and perfectly."
