Physics, not metaphysics
Ida opened her 1974 talk at the California Foundation for Healing Arts with what was, for her audience, a counterintuitive apology. The room was full of people who had come to hear about consciousness, energy fields, and the body as a vehicle for spiritual transformation. Many were practitioners or seekers in the broader human-potential movement. Ida walked to the podium and asked them to forgive her — because she was going to talk about physics. Not metaphysics. The premise she wanted them to hold was that metaphysics was more firmly founded when it had its two feet in physics, and that there was no earthly reason the conversation about Structural Integration should begin anywhere else. She would sit down, she said, and talk about the physics of the physical material world. The framing matters because it set the terms for everything that followed in that lecture, and in the larger doctrine: the work she developed was not a spiritual technique that happened to involve hands on bodies. It was a mechanical intervention into a plastic medium, justified by laws of physics, and demonstrable in laboratories.
"And this book is a compendium of the questions that people usually ask, and you may well find it helpful that abstract will give you an idea of whether you really want it. And because I have a feeling that we're going to be running out of time at the end, I've put this in at the beginning for your pleasure and information, I hope. Now I am up here today, and I think the first thing I'd better do is to apologize to you all and to ask you to forgive me, because I am going to talk about physics and not metaphysics. Metaphysics. I have a premise that metaphysics is much more firmly founded when it has its two feet in physics, and there is no earthly reason why this should not be. So I am going to do a little talk talking about physics the physics of the physical material world. I think if you don't mind, I'll sit down and be a"
Opening her 1974 Healing Arts lecture, Ida sets her terms before she begins.
The Big Sur advanced class of 1973 gives the same line in different words. Teaching a roomful of practitioners who already worked with the body, Ida wanted them to understand that the word structure in their hands was not a poetic word. It was a word about relationship in space, and the laws governing those relationships were physical laws, taught in physics laboratories. She had no use for the suggestion that something occult or metaphysical was happening when she pressed her elbow into a quadratus. The plasticity of fascia was a property of a collagen protein; the changes in the body's contour after a session were changes in the position of mineral-bonded fibers; the new ease the client felt after the work was the result of energy added to an elastic medium under pressure. None of this required spirit, religion, or higher consciousness as an explanatory frame — though Ida did not deny that consciousness changed, only that consciousness was the lever.
"The fascia envelopes are the organ of structure, the organ that holds the body appropriately in the three-dimensional material world. Now nobody ever taught this in the medical school as far as I know. And anytime you want to get into an argument with your medical through they'll realize that this is so. It is the fascial aggregate which is the organ of structure. And the structure basically the word, where we use the word structure, we are referring to relationships in free space. Relationships in space. There's nothing metaphysical metaphysical about it."
Big Sur advanced class, 1973, defining the operative term.
Not medical treatment, not therapy
If physics was the right frame, what was the wrong frame? Two wrong frames recurred in the questions interviewers and audiences brought to Ida: was Structural Integration a form of medicine, and was it a form of spiritual healing? She rejected both. The medical rejection mattered legally and professionally — she was not licensed to practice medicine, her practitioners were not, and the work was not aimed at curing disease. But it also mattered intellectually. Medicine, in her account, had become the chemical school of healing about a hundred and twenty-five years before she taught the 1973 Big Sur class. The structural school had been pushed aside in that triumph of chemistry, and what she was offering was a return to a more fundamental relationship between the body and the field of gravity. To be confused with medicine was to be misunderstood at the foundational level. The line she returned to, almost as a refrain in interviews, was that medical improvements were a byproduct, not a goal.
"Rolfing, you say, is definitely not a medical treatment. Isn't educational It's definitely not a medical treatment. There are many medical improvements that show up. But I always say to them, Well, that's your hard luck. If you've lost your indigestion or your constipation or something, that's your hard luck. We didn't set out to do it."
An interview from the early 1970s, pressed on whether the work is medical.
The same refusal extended to the word therapist. Even when she introduced the phrase that became her most quoted line — gravity is the therapist — she was careful, in the 1971 IPR convention talk, to specify what she did and did not claim. She was not the therapist. The practitioner was not the therapist. The work prepared the body so that gravity, the actual therapist, could do its job. The distinction is more than rhetorical: it removes the practitioner from the role of healer, removes the client from the role of patient, and locates the agent of change outside the room entirely, in the field of the earth. This is one of the moves that distinguishes Ida's framing from almost every other body practice of her era.
"and I make no claim to be a therapist, but I do make a claim that says that Rothschild changes the basic web of the body so that that therapist's gravity can really get in there."
From the 1971 IPR convention talk, Ida specifies her claim — and what she will not claim.
By 1971, in the same conversation that produced the gravity-is-the-therapist formulation, Ida was being interviewed in a format she did not love. The interviewer was trying to gather material for a radio piece introducing the work to listeners who had never heard of it. He kept asking for the basic interview answers: what is the practice, what is the underlying philosophy, who benefits. Ida directed him to a talk she had given the day before, which she felt had been more carefully prepared. But when pressed, she did answer — and her first move was to correct his terminology.
"What we're really doing is a personal treatment in the sense that whereas while we're dealing with, while our hands are manipulating bodies, what we're really creating is a change in the personality."
Interviewed in 1971, Ida corrects an interviewer who called the work a body treatment.
When colleagues reached for spiritual language
Ida did not work alone. Her circle in the early 1970s included theologians, ministers, and scientists whose own frameworks were larger than physics. They came to the work from outside the discipline, looked at what it did to bodies, and reached naturally for the language they already used — spiritual energy, integration of the triad, alignment of microcosm and macrocosm. Ida did not silence them. Several of these voices speak in her 1974 Open Universe class series, and she let them speak. But she also marked the boundary. She listened to her colleague the Reverend Heider deliver a long meditation connecting the practice to Plato, Galen, and the concept of spiritual energy — and she nodded when he himself said, in the middle of his own talk, that the practice was not a religion. The careful preservation of that disclaimer, even in the middle of a sympathetic theological framing, tells you something about the rules of the room.
"I have the feeling that Rothen comes closer to recognizing spirit as the life force and to seeking to make it unitive more than any group that I have investigated or interested myself in. The others still put life into happy categories or unhappy categories. The medical profession, generally, The colleges, generally. The church, generally. Happily, happily into categories. Now Rolfing isn't a religion, but I had this feeling that Rolfing came so close that I wanted to I was thrilled when doctor Ida told me she said, you know, she used this phrase, and I've been using it for years, we've never discussed it. She said, I want to have more to say about the total person, the total person. That really, you know, hit me because that's what I was interested in. I want to tell you something."
Reverend Heider, addressing Ida's 1974 Open Universe class, marks the line even while crossing toward it.
Heider's framing was the most ambitious of the spiritualizing readings, and Ida tolerated it. He went on to articulate the principle that, for him, the work served: the microcosm man must be structurally integrated to the macrocosm, the universe, or the cosmos. He framed exercises he had developed in those terms. He cited Plato and Galen, he cited Albert Schweitzer. He worked his way toward a position where he could call spirit a force, and Structural Integration a means by which that force could integrate the triad of body, mind, and spirit. None of this came from Ida. None of it was endorsed by her. But she did not interrupt it, and she let the disclaimer — the work is not a religion — sit in the middle of it as the load-bearing concession.
"And come to Thayer, who said, when I speak of spirit, I am speaking of spiritual energy. Now, this, I think, brings us closer to the heart of spirit as I at least am trying to view him or it tonight. A spiritual energy. If it is possible that this spiritual energy is so important as the that it will cause the integration of the triad, then this is something that we can well consider and we can well perhaps work with. And I'm sure that what I have heard of Rolfing and of Rolfers and the hours that I have spent not only in Rolfing but in conversation with doctor Ida, I don't know. What I am saying may be Rolfing's viewpoint of spirit and may also give us an insight into spirit's view of Rolfing. Because if spirit is this force, then we can begin to work with it."
Heider follows the line back through medical history to land on spiritual energy.
The other colleague who pressed in this direction was Valerie Hunt, the UCLA electromyographer who became one of Ida's closest scientific collaborators. Hunt was a physiologist by training, but she had also developed a deep interest in human energy fields, auras, and the relationship between connective tissue and what she called the cosmos. Hunt's contribution to the 1974 Healing Arts conference moved freely between electromyography readings and observations about the aura widening from half an inch to several inches after a session. Ida did not adopt Hunt's framework, but she also did not reject it. She let Hunt deliver her findings in Hunt's own terms, even when those terms reached into territory Ida herself would have refused to occupy.
"Well, I think it is through the senses, the brain, the central nervous system that our system is closed. And what I believe is that the dynamic energy fields are received through possibly the acupuncture spots, which exist all over the body. There are many many many thousands hundreds. The great web of connective tissue which supports us which causes our confirmation which causes the very nature of our functioning which separates tissue from tissue which differentiates us in all senses, which is the most extensive tissue we have in the body, is the weigh in of the energy fields. Rolfing by reorganizing and freeing the body in its primary and most basic receptive and responsive modes. Receptive meaning the energy fields entering and responsive meaning the energy fields being dissipated. I think this makes possible a quality of experience which is open and dynamic. And once it is open, then the mind, the body and the spirit do operate in magnificent symphony. And I think it has to be opened that way."
Hunt, in the 1974 Open Universe class, speculates well beyond Ida's framing.
Hunt went further still in another segment of the same series, proposing that the practitioner himself was a transducer of energy between two people, and that the rapport between the client and the practitioner accelerated whatever change occurred. This is the kind of claim that, if Ida had made it, would have placed the work somewhere in the category of laying-on-of-hands or therapeutic touch. She did not make it. Hunt made it, and Ida let the recording roll. The pattern across the transcripts is consistent: Ida held her own framing rigorously to physics, plasticity, and gravity; she let her collaborators frame the same phenomena in larger languages, and the contrast between the voices is itself part of the historical record.
"The other I don't know whether it's by the process of structural integration they become transducers, whether it's the people of that are chosen to be Ralfords or whether Ida Zapsums. But I'm sure they're transducers and it is a relationship between two people that makes what happens happen. It is in addition to the technique. I think this cannot be duplicated by exercise, by oneself. I'm quite sure it cannot be duplicated by machines or gadgets that exercise us, that make changes in the body. There are many, many aspects of what goes on in structural integration. I believe the very personal element of the roffer is major in facilitating energy flow. In other words, if you get roffed, it's great if you love your roffer. I think it will happen if you don't, but I think certain energy flow will take place faster. My final reports will be worked on this fall and this winter for the professional group as well as for lay groups through the Rolf Institute."
Hunt, in the 1974 Healing Arts conference, proposes that the practitioner is a transducer.
Personality changes — but the mechanism is mechanical
The seeming paradox in Ida's position is that she insisted, repeatedly and clearly, that personality changed under the hands. She did not deny consciousness shifts. She did not deny that clients reported feeling more themselves, more present, more capable of insight. She quoted Fritz Perls on the insights he had had since being worked on, and she did so with evident pleasure. The change in personality, for her, was the entire point. What she refused was the inference that, because personality changed, the mechanism must therefore be spiritual or psychological. The mechanism was mechanical. The fascia was a plastic medium; the practitioner added energy through pressure; the relations between segments of the body shifted; the body came nearer to vertical; and as the body came nearer to vertical, gravity supported it rather than dragging it down. The personality changes followed from the mechanical changes, not the other way around.
"And this is indicative merely of the fact that we are going into an unknown territory, a terra incognita, and trying to find out what changes in that body are going to develop into what changes in the personality that calls itself the owner of that body. And I'm talking here about energy being added by pressure to the fascia, the organ of structure, to change the relation of the fascial sheaths of the body, to balance these around a vertical line which parallels the gravity line. Thus, we are able to balance body masses, to order them, to order them within a space. The contour of the body changes, the objective feeling of the body to searching hands changes. Movement behavior changes as the body incorporates more and more order. The first balance of the body is a static stacking, but as the body incorporates more changes, the balance ceases to be a static balance. It becomes a dynamic balance. These are the physical manifestations of the increasing balance, but there is an outgoing psychological change as well toward balance, toward serenity, toward a more whole person. The whole man, the whole person evidences a more apparent, a more potent psychic development."
Healing Arts conference, 1974: Ida describes the chain from pressure to personality.
The same point comes through in the 1971 interview where Ida corrected the term body treatment to personal treatment. She was not, in correcting that word, claiming that the work was psychological. She was claiming that the work was structural and that structural change had personal consequences. The interviewer was trying to slot her into the category of bodywork, somatic therapy, or one of the new psychological movements emerging from the Esalen circle. Ida refused the slot. The work was personal because it produced personality change; it was not psychological because the means by which it produced that change were structural and mechanical. The distinction is fine but, for Ida, fundamental. It is what separates her doctrine from every form of psychotherapy and every form of religious or spiritual practice.
"Rolfing upsets the disequilibrium, there isn't any doubt about it, of connective tissue realigns it. In relationship to the environmental field, that is obvious. We've accepted that as an idea. But it also brings the thought to the surface many of these thoughts I am talking about, the thoughts and emotions and our interpretation of those which is the physical manifestation of the body. And it is through this channel that I think Rolfi makes a tremendous contribution. It is not one that is easily evaluated in our laboratories. This is why I think there is a more permanent change to this kind of education than there is to track and field. I am not against track and field now. I think it has a role but I do not think it has the same kind of role in the development of body that we have thought of in the past."
Heider, in the 1974 Open Universe class, articulates what Ida insisted only structural means could deliver.
What Hunt's instruments measured
The clearest counter-evidence to any spiritualizing reading of Structural Integration was, for Ida, what the laboratory found. She returned to this repeatedly. Valerie Hunt's electromyography at UCLA was, in Ida's framing, the validation that placed the work inside the territory of science. Hunt and her collaborator Don Howell measured electromyographic and electroencephalographic changes before and after sessions. They found shifts in the frequency of muscle firing, in the smoothness of recruitment, in patterns of energy release. These findings were not metaphysical. They were numbers from instruments. Ida took pride in the fact that the work was beginning to lend itself to measurement, because measurement was what would eventually make replication possible — and replication was what would distinguish the work from religion.
"It is the kind of thing you experience when you're out playing golf and that one time you hit that ball magnificently and it took off and it was no effort, and you're always looking for it again. We find that when people become more skillful in a particular high level task, they become what we call more finalized. There's a lot of research on this to show that the frequency actually changes. I think that Rolfing brings a downward shift. There is another level of control that we call the midbrain, and this area also can turn on muscles. We can operate on it. It is one of our very basic areas for some of our primitive movement, and it primarily innervates the great large joints of the body and those which are proximal, such as the shoulders and the hips and the trunk one of the areas that Rolfing works a great deal upon. This has a tendency to produce a very rhythmic quality of movement. And then there, of course, is that cortex that louses us up in so many ways. It can do those fine things with the hand and the beautiful nuances in the face, but it is totally inefficient, inefficient. It louses up, its pattern is not well established."
Hunt, reporting at the 1974 Healing Arts conference, describes the EMG findings in physiological terms.
The interpretive question — what did the EMG readings actually mean — was where the language got more careful. Don Howell, working alongside Hunt, framed the entire project of measurement in explicitly anti-mystical terms. He warned against relying on brain-wave measurements whose physiological basis was still poorly understood, citing the embarrassing finding that delta patterns could be recorded from a bowl of jello. The job of the scientific investigator was to be exceedingly careful about what parameters one chose, and to ground the intuitive perceptions of the experienced eye in measurable physical quantities. Howell's contribution to the same 1974 conference was, in effect, a methodological rebuke to anyone who wanted to make easy claims about the work.
"Recent evidence even suggests that the alpha wave, the so called meditation pattern, is an artifact and it has long been known that delta patterns can be recorded from a bowl of jello dessert. One is reminded of a brainwave researcher's creed, I'll see when I believe it. To clarify then the changes initiated by structural integration, we must be exceedingly careful and selective in the parameters we so choose. A simple before after photograph has long been employed as an effective representation of the gross structural changes brought about by Rolfing. This is so because a picture, even though simple static two and dimensional, is at least a representation of the man as a whole? Much more striking to the experienced eye is the changed movement of individuals as they are processed. What is it exactly that these observers see? Is it objective and can it be quantified? Does it give us a framework with which to eventually explore the physiochemical basis of these changes? I believe that there is just such a precise objective integration integrating notion that can aptly applied to this problem. It is the concept of energy. In physics, long before the molecular statistical mechanical explanation, the gross properties of matter were described by the laws of thermodynamics."
Howell, at the 1974 Healing Arts conference, warns against premature claims based on brain-wave evidence.
Howell went further in the same talk, building a model in which the body could be analyzed as a mechanical system of joints, springs, and dashpots, with energy sources interrelated through myofascial investments. The framework he proposed — viscous elements becoming more elastic, energy flow improving between joints, the system as a whole approaching a resonance condition — was an entirely physical model. No spirit entered it. No higher consciousness was required. The changes were predicted from the model, then measured in the laboratory. This was the kind of validation Ida wanted, because it located the work where she insisted it belonged: in the discipline of physics applied to a plastic biological medium.
"Specifically, we have a mechanical system of joints, articulations, energy sources springs and viscous damping forces Action at a joint is then represented by a lever powered by an energy source driving a spring and dashpot parallel. These various module organs would be interconnected by networks of parallel combinations of elastic and damping components. Considering first action of a single joint, we see that the viscous elements greatly outweigh the elastic ones, motion will be impeded and energy wastefully dissipated. The problem is compounded when one realizes that all of the individual energy sources are interrelated through myofascial investments. If we examine a simple act such as walking in the light of this model, it is apparent that for maximal efficiency these various energy sources must operate in precise, synchronous, often reciprocal patterns. If the interconnecting networks are overly viscous, then no one joint can be moved without dissipating energy throughout the entire system. If by some process the viscous elements could be changed into more elastic ones, what would the model predict? Clearly, an increased capacity for energy flow between joints is to be expected. Know that this itself will affect an overall change toward more rhythmic efficient energy flow is not true."
Howell, in the same 1974 talk, builds the mechanical model of the body's energy economy.
Education, not therapy
If not religion, not medicine, not therapy — then what? The word Ida reached for most often was education. She called the practitioner a highly trained individual whose first year was spent reading biology and physiology. She called the work a development, an evolution, a leading-out. She used the word education because, etymologically, it meant exactly that: a drawing forth of what was already there in the body. The work did not add anything foreign. It did not introduce new chemistry, new tissue, new energy from outside. It rearranged what was already present so that what was already there — the body, gravity, the relationship between them — could function as designed.
"I don't call this a therapy. I call this a development. I call it an education, an a leading out, an evolution. Anything you like, but not healing, not therapy. And in getting yourself, your two feet firmly fixed on this idea, you are taking yourself out once and for all, and I mean for all, from the domain of the medics whose job is therapy and see that you stay out of there and see that you don't behave so that other people get the notion that there is therapy going on, that there is repair going on, that there is medical healing going on. This the acute situation is the job of the medic. The chronic situation is your job because chronic situations all have to do with improper structure. All chronic situations as far as I have ever been able to think, and I've done a lot of thinking about it. All chronic situations involve a problem with gravity, a distortion from the point of balance, a permanent distortion from the point of balance that cannot through your mind be remedied. That is the chronic situation. If you can remedy simply by taking thought, I don't think it's a chronic situation."
In a public lecture, Ida draws the boundary between therapy and education.
The educational framing also accomplished something the medical and spiritual framings did not: it placed responsibility for change inside the work itself, rather than in the practitioner's hands or in some higher source. Ida was emphatic that hands could never do the job alone — the client's movement, after the hands had freed the structure, was what actually integrated the change. The practitioner prepared the body. The client lived in it. Gravity completed the work over time. None of these agents was supernatural; none required belief; none required a relationship with the practitioner that resembled the relationship between a believer and a guide. It was a technical education delivered through a plastic medium.
"And so I ask you that you look at this the next time you are inclined to complain because it is being suggested that you take further training in Rolfing and actually recognize the fact that that which worked five years ago, six years ago, ten years ago, It still works, but it doesn't work well enough, it doesn't work deeply enough, it doesn't get where we should be going in order to show what Rolfing really can do. Rolfing in the sense of this deep changing of the patterns of the fundamental structure of the body to conform with gravity. I have written, as I think probably all of you know, gravity is the therapist, and this is true and I make no claim to be a therapist, but I do make a claim that says that Rothschild changes the basic web of the body so that that therapist's gravity can really get in there. And I think and trust that all of you are willing to subscribe to that claim and to spread it."
From a 1971-72 IPR convention talk, Ida insists the work has had to change with the times.
The point about revelation is worth pausing on. Ida explicitly rejected the notion that Structural Integration was a closed-end revelation. Religions tend to be closed-end revelations: the doctrine is given, the practice flows from it, the believer accepts or does not accept. Ida's framing of her own work was the opposite. The doctrine, she said, was open-ended. It had been incomplete in 1965, was incomplete in 1973, would be more developed by the time her students taught their students. What she had given the world was a method, and the method would continue to evolve as more was understood about the body, fascia, and the gravitational field. This is not how religions describe themselves. It is how research disciplines describe themselves.
"There never was a closed end revelation, not in the history of the world or the history of the world. Everything that can be regarded as a revelation is open ended. In terms of sense. Now it wouldn't hurt us to talk about that last sentence right here in the middle because it is true. We got off on this table one day last week. Function can, will, and does What goes on to change it?"
From the 1973 Big Sur class, a brief but pointed disclaimer about revelation.
The plastic body and the laws of physics
If religion was off the table, what stood in for it as the explanatory frame? The single most important concept Ida returned to was the plasticity of the body. The phrase the body is a plastic medium recurred in nearly every lecture she gave between 1971 and 1976. It was the technical claim around which everything else organized. A plastic, in the dictionary definition she favored, was a substance that could be distorted by pressure and then, by suitable means, brought back to shape — provided its elasticity had not been exceeded. The body, she argued, had been being deformed by gravity since birth, and no one had thought to reform it because no one had recognized that the body was plastic enough to be reformed. This claim was not metaphysical. It was a claim about a material — the collagen protein of connective tissue — and the conditions under which that material could be reshaped.
"Two factors contribute to this: the first that the body, seemingly a unit, is in fact not a unit but a consolidation of large segments: the head, the thorax, the pelvis, the legs. The relation of these segments can be changed because the connecting myofascial structure is a structure of connective tissue of collagen. This is what that myofascial body is about. And collagen is a unique protein. The collagen molecule is a very large protein and it is a braiding of three strands a special braiding. These three strands are connected by various inorganic hydrogen sometimes, sodium sometimes, calcium sometimes, and undoubtedly other minerals. These minerals are interchangeable within limits. Thus, as the body grows older and stiffer, undoubtedly a larger percentage of calcium and a smaller percentage of sodium are present in these bonds. But by the addition of energy and what is energy? In this come in this context, it can it is the pressure of the fingers or the elbow of the ralpha. This ratio may be varied by the addition of this energy, and the joint or the connective tissue becomes more resilient, more flexible."
Healing Arts, 1974: Ida unpacks what plasticity means at the molecular level.
Notice what this account does, and what it does not do. It does not invoke energy in the sense of vital force, prana, chi, or any of the energies that animated other body practices in Ida's era. It uses the word energy in the sense the physics laboratory uses it: pressure on a substance, measurable in foot-pounds or joules, capable of changing the molecular configuration of a protein. The practitioner's elbow on the client's tissue is, in this account, an energy source the way a hammer striking a piece of metal is an energy source. The change in the tissue is the change in the molecular bonds. Nothing else is happening, and nothing else needs to be happening to explain what is observed. This is what Ida meant by anchoring the work in physics.
"It's pure physics as it's taught in physics laboratories. Now the strange part about it is that that organ of structure is a very resilient and very elastic and very plastic medium. It can be changed by adding energy to it. In structural integration, one of the ways we add energy is by pressure so that the practitioner gives deliberately contributes energy to the person on whom he is working, to not energy in the sense that you let a position throw it around, but energy such as they talk about in the physics laboratory. When you press on a given point, you literally are adding energy to that which is under that point. And in structural integration, by way of an unbelievable accident of how you can change fashion structure, you can change human beings. You can change their structure and in changing their structure you are able to change their function. All of you have seen that structure determines function to a very great degree, to a degree which we can utilize. Now the basic law of law of law law is that you add structure to the body and in so doing, that you add structure you add energy to the body, and in so doing you demand all of you are going to hear a great deal more about this as time goes on. But this is the basic reason why structural integration works."
Big Sur, 1973: Ida states the basic law of the work in physical terms.
Ida built her larger account of why the work succeeded on this foundation. The body, she said, becomes more orderly under pressure. The myofascial relationships balance around a vertical line. The vertical line parallels the gravity line of the earth. When body verticality coincides with gravity verticality, gravity reinforces the body's energy field rather than draining it. The body, in her phrase, becomes nourished by the gravitational field. This is what produces the change in behavior, in consciousness, in personality that her colleagues described in spiritual terms. The mechanism, from start to finish, can be stated in the language of vectors, fields, and material plasticity. No part of it requires belief.
Structure, not posture; relationship, not placement
One of the ways Ida policed her vocabulary was by distinguishing structure from posture. The distinction was not trivial. Posture, she pointed out, was the past participle of a Latin verb meaning to place — implying that something had been put somewhere and was being held there by effort. Structure, by contrast, named a relationship in space, not a placement. The other manipulative schools — chiropractic, osteopathy, the postural-education schools like Mensendieck — were, in her reading, ultimately about placement. They sought to put the body where it should be. Her work, she argued, was about establishing relationship so that the body did not need to be placed at all. The body in good structural relationship would land in good posture automatically; the body in poor structural relationship would lose its posture the moment the will relaxed. This was a technical distinction, not a spiritual one, and it pointed to why she did not consider her work part of the larger family of postural therapies.
"It's relationship wherever you use the word structure, you are really talking about a relationship. You talk about this beautiful structure, you are talking about the way the top relates the middle, relates to the floor, the shape of the ground. All of this is implied when I say, I was in a beautiful structure tonight. Structure, wherever you use it, is relationship, and it is particularly relationship of parts in a body. This constitutes structure. Now posture is something else again. And the boys that devised the word posture knew what that something else was because the word posture means it has been placed. It is the past participle of a Latin word, to place, and it means it has been placed. And when you use the word posture, you are saying it has been placed. Somebody has placed something somewhere. Somebody is maintaining the placement of something somewhere. Somebody is working to keep something placed somewhere. And I guarantee that there is no one in this room who doesn't know that in this day and age of the what is it? Nineteen twentieth century, last part of it, last quarter of it, that to keep any of these bodies in posture takes effort, constant continuous effort. And when you have to make effort concerning anything in your body, it's a very bad sign. You don't usually interpret it in view of the next words."
From a public lecture, Ida draws the distinction between structure and posture.
The distinction also let Ida explain why her work was not in the same category as the schools that competed with hers. Osteopaths and chiropractors, she granted, did real work and got real results. But their results were results of placement: pushing a vertebra back into position, snapping a joint into alignment, restoring an articulation to where it was supposed to be. Her work did not push anything into place. It changed the relationships of the soft tissue that held the segments where they sat, and the segments then floated to whatever position those new relationships allowed. The work was, in her phrase, about establishing balance through relationship. This is a substantively different theoretical claim from anything the placement-based practices offered, and it is also a substantively different claim from anything religion offered.
Why the line mattered
Reading the transcripts in sequence, one feels Ida's care in maintaining the line as something more than a personal preference. She was protecting the work. The years she taught publicly — 1971 through 1976 — were years when bodywork in America was rapidly being absorbed into the New Age. The Esalen circle that had nurtured her early teaching had grown into a sprawling counterculture in which somatic practices were routinely framed as paths to enlightenment. Many of her own students embraced this framing enthusiastically. Ida understood the appeal — she did not condemn it — but she saw the cost. If Structural Integration became a spiritual practice, it would lose what made it different: the claim that it could be measured, replicated, taught as a technical discipline, and validated by laboratory science. The minute the work crossed into religion, it would no longer be science, and the larger validation she sought would be foreclosed.
"And even though you did not mention it in your remarks then, I thought for the moment that we're speaking of your work as a chemist, that you might suggest how the law of entropy fits into your conception that later developed into Rolfing. I'm sorry, this is brand new idea to me and I'm afraid I'm going to have to take some time to think about it. Ask me a couple In more that the disordered structure tends to create greater entropy less Yes, the no question about that. There's no question about that. But that hardly needs physics. That needs just common sense to see that. Yeah. Seems to me. Yes. I don't see how anybody with eyes on their heads can expect that a very disordered body carried in a fashion which it never was designed for can fail to be disorganized and not be able to perform as it was designed to perform. You understand that gravity is, biologically at least, gravity is accepted as a positive force by living bodies. Is that As a positive force in As a positive thing to be used if the body is in structural alignment. Oh, I think there's no question about that, and I think that we show the evidence of this day by day in our work."
Interviewed in 1974 about her chemist's background and the law of entropy.
The line also mattered for the practitioner. If the work was spiritual, the practitioner became a kind of priest, and the work became a kind of devotion. If the work was therapy, the practitioner became a kind of doctor, and the work became a kind of cure. Both framings would, in Ida's view, distort what actually happened in the room and lead practitioners to ask the wrong questions about why the work worked. She wanted them to ask physical questions — about the fascial position, the vector of pressure, the relationship of segments, the verticality of the line — because physical questions had physical answers and physical answers could be tested in the next session and the next client. Religion did not work that way. Therapy did not work that way. Structural Integration, in her account, did.
"And only now, this is coming up again, And And I am saying to you, and I don't get to how many people say this, that we have a more fundamental way, a more basic way of dealing with structure Now the reason we have this way is because we have become sufficiently sophisticated to understand that structure is determined by the relationship of the individual body to the gravitational field. This is what often has offered in addition to any other school. What's the difference between this and this? Is the answer. We are the only group who recognize that in order for a living body to be at ease in its spatial environment on the earth, it must deal positively with gravity or rather gravity must deal positively with it. Because what we here in Lawton are here to do, we can't change the gravitational field. This is odd, but we just have nothing that means yet. But what we can do is to change the way the parts of the body that I have already referred to, how they fit together into a whole which can transmit the gravitational field. And in its energy, which is the energy of the earth, in its transmitting of that, it enhances its own energy field. You can change the body by virtue of the fact that its segments are segments of a whole and then the gravity can flow through. Now this is the basic concept of Rolfe. And tomorrow when I get you all together on the griddle, I'm going to ask you for this answer over and over again in many, many different forms."
Big Sur, 1973: Ida names what is distinctive about the work she developed.
The contrast becomes sharpest when one of Ida's contemporaries in the wider human-potential field tries to fit the work into a magical or consciousness-based framework. In a 1974 Open Universe class, a colleague engaged in a long conversation with someone who treated cancer through magical and consciousness-based methods was asked directly how the work fit into that magical system. The answer, given by an articulate practitioner of those methods, is striking for its honesty: it does not fit. The work is a physical thing. It does a tremendous amount of good. It produces realignment that has consequences on many levels. But it is, fundamentally, a physical intervention — and the speaker locates its primary value in what it does to the body, leaving the more cosmological claims as speculation.
"I've made the mistake of healing people with cancer and having them go out and commit suicide or kill others on a freeway accident, things like this. It's not a good thing to do. So, yes. You talk a while. I'm sick of hearing myself talk. No, but I want to know how you put the Rolf technique, the Rolf system into the magical system. I don't. I think it's a physical thing that does a tremendous amount of good. I've been Ralph and I love it and I know people before and after that were horrible examples before and good examples after. I kind of think that when you move the blockages around that you realign them on many levels besides just physically."
A practitioner of magical healing is asked how the work fits into his system. His answer is unexpectedly modest.
Coda: the chemist's discipline
It helps, finally, to remember who was saying these things. Ida Rolf took her doctorate in organic chemistry from Barnard College in 1916, at a time when few American women earned doctorates in research science and fewer were employed in research institutions. She was hired immediately by the Rockefeller Institute, where she worked on the problem of synthesizing a non-toxic American version of the antisyphilitic salvarsan. She spent time in Europe in the late 1920s, sitting in on lectures by Erwin Schrödinger at the University of Zurich. By the time she developed Structural Integration in the 1940s and 1950s, she had spent decades inside the discipline of laboratory chemistry, where claims were tested, measurements were taken, and theories that could not be reduced to physical mechanisms were discarded. That training is what one hears in the transcripts. When she said not religion, not spirit, she was not making a polemical move against her spiritualizing colleagues. She was naming the discipline that had given her the work in the first place, and the discipline she insisted her students inherit.
"Rolf was born, raised, and educated in New York City. She received her PhD in 1916 from Barnard College as a research chemist. Now at that particular time, few American women sought degrees as research scientists and still fewer were given employment in research institutions. Ida Rolf was immediately hired by the Rockefeller Institute. In the late 1920s, Doctor. Rolfe was sent to Europe by the Institute, and it was during that time that she sat in on some lectures of Erwin Scheddinger at the University in Zurich. She began to suspect that there was a direct relationship between human behavior and both body physics and body chemistry. This was the genesis of the idea of structural integration."
From the biographical introduction to Ida's 1974 Structure Lecture, the chemist's background that shaped the doctrine.
What she insisted on, finally, was a question of intellectual honesty as much as professional positioning. She had a hypothesis: that structural change in a plastic medium under measured energy input would produce predictable physiological and behavioral change. That hypothesis could be tested. It was being tested, in Valerie Hunt's laboratory at UCLA, with electromyographic and electroencephalographic instruments. The results were beginning to come in. If the work were called religion, or spirit, or therapy, none of that testing would matter — because religions are not tested by EMG, and spirits do not show up on encephalographic readouts. Ida wanted the work to be tested. So she protected it from the categories under which it could not be tested. The discipline of saying not religion, not spirit was, in the end, the discipline that kept the work open to the verification she had been pursuing since 1916.
