The Physician and the Priest

In all thy getting, get understanding. — Proverbs 4:7

A Word of Thanks Before the Caution

It is worth beginning with the gratitude, because the caution will read as criticism and it is not meant as one. A large amount of money, talent, and institutional energy is now flowing toward the problem of health, and a great deal of it is flowing toward problems that the older system left unsolved. The cost of care has been climbing for decades along a curve that everyone inside the field can see and almost no one has been able to bend. The experience of being a patient — waiting, fragmented records, advice that arrives too late to prevent anything — is bad enough that the people trying to rebuild it from the ground up deserve a hearing rather than a sneer.

The builders running these experiments are not the dumbest people in the room. They are frequently the most capable, and they are right about a great many things. They are right that the system optimizes for acute rescue and neglects prevention. They are right that a person should be able to see their own biological data and act on it without asking permission. They are right that a category as large as the supplement industry has operated for a long time with very little independent verification, so that a shopper genuinely cannot tell the trustworthy product from the worthless one. These are real failures, and the attempt to fix them is a real good. Nothing that follows is a retraction of that.

The caution is narrow and specific, and it is aimed at a single failure mode that good intentions do not prevent. It is the failure that occurs when the same hand comes to hold the measurement, the interpretation, and the supply — when one worldview is positioned to decide what gets measured, what the measurement means, and what you should buy or do in response. That concentration is not evil in itself. It is a position. The question this raises is the same question raised everywhere that scale concentrates: what does the one who holds the position owe to the person who must pass through it, and is the person still free to disagree?

How We Got Here, Briefly and Honestly

The present moment did not arrive out of nowhere, and the history is more interesting than either of the cartoon versions of it. The first cartoon says that modern medicine was a clean triumph of science over superstition. The second says that it was a deliberate conspiracy to bury natural healing. Neither survives contact with the record, and the truth between them is the part worth knowing.

At the start of the twentieth century, American medicine was plural. A person seeking care could choose among competing schools — conventional, eclectic, homeopathic, naturopathic, osteopathic — that disagreed with one another about the nature of disease and the means of healing. Some of this plurality was knowledge worth keeping; some of it was quackery that killed people. In 1910, the Carnegie Foundation published a survey of medical education written by Abraham Flexner, an educator who held a bachelor's degree and had never formally studied medicine. The report set a single standard — laboratory science, research-based curriculum, hospital-based clinical training — and measured every school against it. The schools that could not meet the standard were declared inadequate. The capital to implement the verdict came in large part from Rockefeller philanthropy, which over the following two decades funded the schools that conformed to the new biomedical model and withheld support from those that did not.

The consequence is not in dispute and does not require exaggeration to be striking. In 1904 there were 160 institutions granting medical degrees in the United States; by 1935 there were 66. The decline of the eclectic and homeopathic schools, which had already begun before Flexner finished his survey, was accelerated and then sealed by the redirection of money toward a single approved model. A plural landscape became a consolidated one, and the traditions that emphasized plants, nutrition, and the relationship between a healer who knew you and a body in its context were pushed to the margins of legitimacy where many of them remain.

Two things are true about this at once, and the honest reader holds both. The consolidated model produced genuine and enormous goods: the antibiotics, the surgery, the diagnostic precision that save lives every day and that the marginalized traditions could not have produced. And the consolidation also imposed a genuine cost: it narrowed what counted as medicine to what the approved model could measure and patent, it replaced the healer who knew your family with the credentialed authority who knew your lab values, and it taught a century of patients to mistrust their own role in their own health. The pattern to notice is not villainy. It is that capital, concentrated, decides which model is visible and fundable, and that the decision then hardens into the only thing anyone can see. (The longer treatment of how this drift entered a single representative family, and how it can be selectively disinherited, is set out separately in the companion essay on the Cleveland record.)

The Same Pattern, Wearing New Clothes

The reason the history matters is that the pattern is recurring in 2026, in a form that is far more capable and therefore far more consequential than anything available to the foundations of a hundred years ago. The mechanism is the same: capital, concentrated, deciding which model of health is visible and fundable. What has changed is that the model can now be assembled into a single closed loop in a way that was previously impossible.

Consider the shape of one of the most visible new entrants, stated entirely from its own public description. A preventative-health company offers its members a battery of more than 160 laboratory markers, at-home blood draws, and AI-assisted MRI and CT imaging. It then announced an artificial-intelligence layer to interpret all of that data and generate personalized guidance. It then acquired a supplement-intelligence platform — one that rates products, tests them against their labels, and tracks what people take — and described the combination, in its own words, as a model in which it can measure the body continuously, understand the inputs acting on it, and improve health through evidence rather than marketing. Read that sequence again, because it is not hidden and it is not sinister on its face. It is a closed loop, openly advertised: the same entity measures you, interprets the measurement, and recommends what you put into your body, then measures again to see whether the recommendation worked.

There is a real good in each link of that loop. Continuous measurement catches disease early. Honest interpretation cuts through noise. Independent supplement testing is genuinely needed; the company's own testing arm reports that roughly half of leading products fail simple label-accuracy checks, which is a service to anyone who has ever stood in a vitamin aisle unable to tell truth from packaging. None of this should be waved away. But notice what the loop also is. It is a single worldview occupying the measurement, the meaning, and the supply at the same time — the precise concentration that the Flexner-era consolidation achieved, now rebuilt as a consumer product and pointed at the individual body. The platform that decides which supplement is trustworthy is the same platform that decides which marker matters and the same platform that decides what your result means. When all three judgments live in one place, the patient has gained a powerful tool and, unless something prevents it, has quietly handed over the one decision that should never leave their hands: the decision about what a healthy life actually is.

The Worldview Underneath the Tool

A tool carries the assumptions of the people who build it, and at the frontier of medicine those assumptions stop being incidental and start determining the choices. This is why it is fair, and not a personal attack, to ask what view of the person sits underneath the capital that is now reshaping health. The view is not concealed; its most prominent voices state it plainly.

The firm that has become the loudest financial architect of this moment describes its healthcare thesis in explicit terms. Medical care, in its published framing, is a service that costs too much and improves too slowly, and the goal is to turn the delivery of care into computation — to convert what skilled humans do into something a machine can do at scale. As an efficiency argument about administrative cost and diagnostic throughput, that is reasonable and even welcome. As a complete account of what care is, it quietly assumes that nothing essential is lost when the encounter between healer and patient is converted into a transaction between a person and a model. Whether something essential is lost is not a technical question. It is a question about what a person is.

And here the most visible figure in that firm has been unusually candid, which makes the disagreement clean rather than speculative. He has said, in public and at length, that he engages in essentially no introspection, that the inner self is an illusion, that human long-term memory is mostly fabricated, and that the notion of self-examination is a recent psychological fad rather than a permanent feature of the human condition. He is entitled to that view, and it is a coherent one with a real intellectual lineage. But it is worth saying clearly what it is: it is the position that there is no enduring soul to be examined, that the felt interior life is a surface effect, and that a person is, at bottom, a process to be optimized. That is a metaphysical claim, not a scientific finding, and it is the operating assumption beneath a great deal of the capital now flowing into the measurement of bodies. A person who believes there is no inner self will build health systems that optimize the measurable body and treat the rest as noise. A person who believes the body houses a soul will build differently, or at least will refuse to let the measurable crowd out the rest. The tools look identical from the outside. The destinations are not the same.

Why the Secular Reader Should Take the Other Side Seriously

This is the seed the essay exists to plant, and it is addressed with respect to the reader who holds no faith at all. You do not have to believe anything about God to notice that the people who hold life to be more than an accident are not, on the evidence, the dumbest people in the room. The history of science is not a history of belief retreating before knowledge. It is, over and over, a history of knowledge rediscovering what an older tradition had already encoded, and arriving at the same destination by a longer road.

Take the single greatest health victory of the modern era, the one that did more to extend human life than any drug or surgery: sanitation and hygiene. The collapse of infectious-disease mortality in the nineteenth and early twentieth centuries came not primarily from medicine but from clean water, waste separation, quarantine of the contagious, and the washing of hands and bodies and garments. This was treated, at the time, as a triumph of modern public health over ancient ignorance. But read the book of Leviticus with a clinical eye and you will find a sanitation code: the isolation of the infectious, the disposal of waste outside the camp, the washing protocols, the handling of bodies and discharge and mold, the quarantine periods. A people moving in close quarters for forty years sustained a level of public hygiene that the great cities would not match again until the nineteenth century, and they did it under a priesthood that framed it as holiness rather than germ theory. The germ theory was not wrong. It was a later, mechanistic explanation for the value of practices that had already been enforced, on other grounds, for a very long time. Science did not defeat the older knowledge. It caught up to it and gave it a new vocabulary.

The honest secular position is not that the ancient frame was right about everything — it plainly was not, and a great deal of pre-modern medicine was useless or worse. The honest position is that a tradition which got the most consequential thing substantially right, for reasons it could not have derived from a laboratory, has earned a seat at the table rather than a dismissal. To treat the people at that seat as fools is not rational skepticism. It is a prejudice that costs the skeptic access to a body of practical wisdom that keeps turning out, on inspection, to have been ahead of the curve.

The Two Ways to Be a Fool

If the argument stopped at defending the older tradition it would be only half honest, because the older tradition has its own characteristic failure, and the failure is lethal. The point of common ground is that there are two ways to be a fool here, not one, and the wise position avoids both ditches rather than choosing a side and riding it into the ground.

The first fool is the optimized specimen. He has driven his body fat to single digits and his blood markers to textbook values. He has measured everything measurable and corrected every correctable number. And he has built his entire understanding of his own life around the assumption that the measurable body is the whole of the person, so that when he dies — as he will, because the optimization buys years and not eternity — he dies having tended the instrument and neglected the one who was supposed to be playing it. His heirs quarrel over the furniture. He won every battle the data could see and lost the war the data could not.

The second fool is the one who saw the first fool coming and overcorrected into a different grave. He decided that because the system is captured and the worldview is hollow, the whole apparatus is evil, and he will have none of it. He treats the hospital as the enemy and the antibiotic as a betrayal, and he dies at the end of a country road of an infection or an obstruction that a first-year resident could have cleared in an afternoon, swearing with his last breath that he kept the faith. He did not keep the faith. He confused the abuse of a good thing with the thing itself, and he made his own body the altar on which he sacrificed to prove a point that did not need proving.

Neither of these men is wise, and they are mirror images of the same error: each took a partial truth and made it total. The specimen made the body everything and lost the soul. The zealot made the soul everything and lost the body that was meant to carry it. The whole of the available wisdom lies in refusing to be either, and it is not a difficult refusal. It only requires holding that the body is real and worth tending, and that it is not the whole of the person, at the same time — which is, not coincidentally, what both an honest physician and an honest priest have always believed.

The Physician and the Priest at the Same Table

The constructive claim is the one the whole essay has been building toward, and it is deliberately modest because modest claims are the ones that travel into rooms where the author is not welcome. The claim is that the durable victory does not belong to either extreme. It belongs to the table where secular science and an enlightened tradition reason together in good faith about a body that neither of them invented.

This is not a sentimental hope. It is the actual historical record of how the goods got made. The man who wrote the Gospel of Luke, the most clinically observant of the four, was a physician, and his account loses nothing of its medicine for being written by a believer. The figure at the center of that Gospel healed people at scale, restored function to bodies, and never once treated the body as beneath his concern or above his power to mend — and also never treated the mended body as the point. The tradition that produced the sanitation code also produced hospitals; the word itself descends from the houses of hospitality that the faith built to care for bodies it believed were more than bodies. The false choice between caring for the body and caring for the soul is not native to the tradition. It is a modern invention, imposed by people on both extremes who needed an enemy more than they needed the truth.

What the table requires is simple to state and hard to practice. It requires the scientist to concede that the question of what a person is for is not answerable in the laboratory, and that a tradition which has been asking that question for millennia is a serious interlocutor rather than a superstition to be managed. It requires the believer to concede that the laboratory is a gift, that the antibiotic and the scan and the early-detected tumor are mercies, and that refusing them to make a point is not faith but pride wearing faith's clothes. Each has to grant that the other is holding a piece of the truth that they themselves cannot supply. When that happens, the patient is the one who benefits, because the patient finally gets the whole of the available help — the measurement and the meaning, the cure and the care, the years and the understanding of what the years are for.

The Decision That Should Not Leave Your Hands

Which returns the argument to where it began, and to the one practical thing this essay asks of anyone who reads it, whatever they believe. The new health platforms are powerful and many of them are good. Use them. Measure what is worth measuring. Take the supplement that the honest test vindicates and skip the one it exposes. Catch the disease early. None of this essay argues for refusing the tools; that is the second fool's error and it kills people.

The single thing worth guarding is the decision the closed loop is built, perhaps without anyone intending it, to absorb: the decision about what a healthy life is for. A system that measures you, interprets you, and supplies you can drift, very gently and with the best intentions, into answering that question on your behalf — into defining health as the optimization of the markers it can see, and a good life as the successful management of a body. That definition is not false so much as fatally incomplete, and the incompleteness is invisible from inside the loop, because the loop has no instrument that can detect what it has left out.

So keep the decision. Let the platform measure the body and keep for yourself the judgment about what the body is for. Let the physician treat the condition and keep the priest, or the conscience, or whatever name you give to the part of you that knows the difference between staying alive and being worthy of the life. The most capable builders of this generation are running experiments that will relieve a great deal of suffering, and we should thank them for it and use what they make. We should simply decline the one trade that is sometimes folded invisibly into the offer — the trade of the soul's jurisdiction for the body's optimization — because that is the one trade that, once made, cannot be measured back. To have arrived at perfect health and have nothing left that the health was for is not a victory. It is the most expensive way there is to lose.

The funding and acquisition facts in this essay are drawn from primary and contemporaneous sources rather than inference. The preventative-health company's Series B (approximately $298 million, at a $2.5 billion valuation, led by Redpoint Ventures, with Andreessen Horowitz among the participating investors, not the lead) and its subsequent acquisition of the supplement-intelligence platform are taken from the company's own announcements of November 2025 and May 2026 and from contemporaneous trade reporting; the supplement-testing figure is the company's own published claim. The venture firm's healthcare thesis, including the framing of converting the delivery of care into computation, is quoted from its own published Bio + Health writing, and its 2026 fund figures are from its own fundraising announcement and corroborating reporting. The statements regarding the firm's most prominent figure — on introspection, the inner self, and memory — are his own public remarks of March 2026 and are presented as his stated view, with which the essay respectfully disagrees on the merits rather than by characterization. The historical account of the 1910 Carnegie report and the subsequent redirection of philanthropic capital relies on the well-anchored figures — 160 medical schools in 1904 falling to 66 by 1935, and the documented decline of the eclectic and homeopathic schools that was already underway before the report — rather than on the larger and less well-sourced figures that circulate in popular retellings; where this essay declines to repeat a dramatic number, it is because the number could not be traced to a primary record. The companion treatment of the Rockefeller family record across five generations is published separately under the WellSpr.ing record. This essay is offered as an invitation rather than an indictment: it names a worldview and a structural risk, not a culprit, and it holds that the people building these systems are owed gratitude for the genuine goods they are producing even as they are asked to leave intact the one decision that belongs to the patient alone. In all thy getting, get understanding.
