One Eighth of an Inch: Julian Jaynes, the Bicameral Mind, and the Bandwidth of God

Start with a measurement, because the measurement is where the famous theory hides its best secret. In The Origin of Consciousness in the Breakdown of the Bicameral Mind, published in 1976, the Princeton psychologist Julian Jaynes had to explain how one half of the brain could hand a finished thought to the other half. He reached for anatomy and found a strip of nerve fiber connecting the two temporal lobes, the anterior commissure, which he measured at slightly more than one eighth of an inch in diameter. That tiny bridge, he proposed, carried the voices of the gods. The width of the channel is the whole argument, and almost everyone who summarizes Jaynes leaves it out.

The Vacuum Where the Evidence Should Be

Zach Bush, a physician in good standing, sits across from an interviewer and describes the soul, calm and fluent, generous with wonder. He says that every millionth of a second the atoms of your body dissolve and return, that a single fertilized cell organizes itself into a child by reading a map no biologist can locate, and that the map lives in the vacuum, in the electromagnetic field that fills the empty space inside every atom. He calls this the anatomy of the soul. In a 2021 essay on his own website he writes that the body projects itself as a hologram, and that its apparent solidity is an impression made by light. The performance is seductive because the vocabulary is real. Differentiation, migration, electromagnetic field, vacuum: each of those words has a home in a textbook. The trouble begins the moment you check whether they are being used the way the textbooks use them, or whether they have been borrowed to dress an idea that biology and physics both reject.

The Glass People: The Materials of Madness, from the Glass King to the Simulation

More than six hundred years ago, the King of France stopped letting anyone touch him. Charles VI had iron rods sewn into his clothing and moved through his palace with the stiff care of a man carrying something breakable, because he believed he was carrying something breakable. He believed it was himself. The chronicles of his reign record that the king became convinced his body had turned to glass, and that a careless embrace or an ordinary stumble would shatter him to pieces on the stone floor.

The Box You Cannot Check

The clinic intake form on the clipboard at the front desk has two boxes next to the word “sex.” A patient who is neither of the two options has been given three choices: pick one box and lie, write something in the margin, or refuse the form. The receptionist will not read the margin. Data entry clerks will not transcribe it. EHR systems will not store anything outside the two values the form lists. The patient walks out of the clinic with a treatment plan based on a box that does not correspond to their body, their history, or their current endocrine state. The form has done its job, which is not the job it claimed to do.

The States That Will Not Be Commanded

There is a class of human experience that answers to no direct order. You cannot tell yourself to fall asleep. The instruction arrives at a locked door. Sleep refuses the simple transaction of command and execution. Instead, it assembles itself once certain conditions are present, and those conditions include, strangely enough, the act of picturing yourself already inside the state you are trying to enter. Lying down begins it. Closed eyes continue it. Imagining yourself asleep, entering the self who has already arrived, completes the condition, and only then does sleep agree to appear.

When the Radiologist Becomes the Expense

On March 25, 2026, at a Crain’s New York Business panel discussion of the city’s hospital sector, Mitchell H. Katz, MD, president and CEO of NYC Health + Hospitals, told the assembled executives what cost-cutting now sounds like in the largest public hospital system in the United States. “We could replace a great deal of radiologists with AI at this moment, if we are ready to do the regulatory challenge.” Sandra Scott, MD, who runs One Brooklyn Health, one of the city’s safety-net institutions operating on tight margins, replied that the move would be “a game-changer.” The exchange appeared in Crain’s coverage of the panel and was picked up by the radiology trade press within forty-eight hours.

The Zeroing of Knowledge: When Everything Is Known, What Remains Worth Learning?

Knowledge used to be expensive. It cost years of apprenticeship, tuition in the tens of thousands, decades of practice, and, more than anything, the brutal currency of time. A physician spent twelve years beyond high school before being trusted to cut into a human body. A lawyer spent seven years and a bar exam before being permitted to argue before a judge. A professor spent a decade accumulating the credentials required to stand before a lecture hall and declare, with institutional authority, that they knew something you did not. The entire architecture of Western professional life was built on a single economic premise: knowledge is scarce, therefore knowledge is valuable, therefore the people who possess knowledge deserve premium compensation for granting access to it. That premise is now dead. It did not die slowly. It was killed in roughly three years, and we are only beginning to understand the corpse.
