Let us imagine an extraterrestrial planet named Covossca where science and technology are very advanced. The scientists know all about their bodies, except for what is inside their skulls. We can imagine that a social restriction prevented scientists on Covossca from ever studying what is inside the skulls of organisms such as themselves. We can imagine that on planet Covossca an all-powerful church in charge of everything prevented all scientists from ever opening up a skull, on the grounds that skulls contained a sacred soul that it was blasphemy to disturb. So the scientists on Covossca knew all about the exact details of their bodily organs underneath their necks, but knew nothing at all about what was inside their skulls.
Let us imagine that upon getting tired of endless pleas from scientists and doctors to allow the examination of the contents of skulls, the all-powerful church finally relented, and finally gave permission for the scientists to examine what was in the skulls of newly deceased people. After such permission was granted, there might be a conversation like this between two scientists:
Aldorus: This is fantastic! We're finally going to get to study what is inside the skull. What types of things will we find?
Beyonus: We will find all of the secrets of mind and memory inside the skull, of course.
Aldorus: How can you know that?
Beyonus: Where else could they be, but inside the skull? We haven't found them anywhere else in the body.
Aldorus: So what type of things should we expect to find? What type of things should we be looking for?
Beyonus: We can expect to find memories. When you open the skull of a dead person, you will find all the knowledge he ever learned, and his memories of all the important experiences he had.
Aldorus: How will those look when we see them?
Beyonus: Maybe they will be tiny little pictures that we will be able to see when examining the matter inside the skull with sufficient magnification. Or maybe there will be tiny text we can read. Or maybe the information will be encoded. In that case it may take quite a while the crack the code. But at least we can be sure we have discovered encoded information as soon as we see it.
Aldorus: Why is that?
Beyonus: Because when information is encoded, there is always a great repetition of a small number of tokens. It's like the letters of an alphabet. The same limited set of letters keeps being repeated over and over again. Whenever you find something like that, you know you have found encoded information.
Aldorus: What other things should we expect to find?
Beyonus: We should expect to find sorting, addressing and indexing. If such things didn't exist inside the skull, we couldn't be able to remember things so quickly. You name some person from history, and I can instantly tell you all about him. That can only occur if there is sorting, addressing and indexing inside the skull which can allow exactly the right information to be found so fast.
Aldorus: Should we expect to find some kind of little widget that reads the right memory?
Beyonus: No doubt! There must be some kind of little thing inside the skull that reads the memories stored there. Maybe like some tiny roving eyeball. Plus there must be some kind of little thing that writes memories, or how else could memories be stored. Maybe it will kind of like a little moving pencil.
Aldorus: But will a man's memories fade between the time he dies and the time we open his skull?
Beyonus: Not at all. People like us can remember what we learned decades ago. So we'll find some stable writing surface where memories persist for decades, like writing chiseled into stone.
Now, let us imagine that the scientists on planet Covossca finally were given permission to open up some skulls of people who recently died. Imagine if they were shocked to find that inside the skulls of everyone they checked, there was nothing at all except a heap of very fine powder, something like the heap shown below:
Would the scientists of Covossca modify their opinions in an appropriate way after such a discovery? They might. But it is as likely as not that they would just cling to the dogmas they had long taught, unswayed by the facts they had discovered. We can imagine a conversation like this:
Aldorus: So now we've finally found what is inside skulls, and it's nothing but a disorganized powder! We must have been all wrong about memories being stored in skulls, and minds coming from inside the skull.
Beyonus: No, no! We just need to study the tiny powder specks more carefully! Maybe there is something about these tiny powder specks that causes them to produce the fruits of our minds: thinking and insight and self-hood and imagination. Maybe there is something very special about the way the tiny powder specks are arranged, that allows them to store memories, and makes possible the instant retrieval of memories.
What has occurred on planet Earth is actually very similar to what occurred in this story about the planet Covossca. Earth scientists have examined very carefully what is inside skulls. They didn't find mere powder. But they did find inside skulls something just as discouraging to all claims that brains store memories and make minds: just a lump of meat with the consistency of jello.
We should ponder very carefully all of the "never-founds" of the brain. These are things that we either should expect or might expect to be found in the brain if it is the storage place of memories, but which never have been found in the brain.
Never-Found #1: Tiny Images in Brains
One way you can imagine memory being stored in brains is by the preservation of tiny images. We can imagine a brain taking periodic "snapshots" of what you see, and then saving such "snapshots." No such thing has ever been found in a brain. No one has ever found anything like photos. No one has ever found anything even as crude as a few dots representing a shape seen. For example, no one has even found in a brain an image as crude as the one below:
Never-Found #2: Tiny Text in Brains
Another way we can imagine memory being stored is by a writing of tiny text. For example, you can imagine someone looking at some brain tissue in an electron microscope, and finding tiny little letters smaller than cells. No such thing has ever been found.
Never-Found #3: Tiny Numbers in Brains
Another way we can imagine memory being stored is by a writing of tiny numbers. For example, you can imagine someone looking at some brain tissue in an electron microscope, and finding tiny little numbers smaller than cells. Such things might exist as numbers such as 83922. Or they could exist through some dot-symbol representation. For example, we can imagine someone looking through an electron microscope to see something like this in the brain, which could be a neural storage of the telephone number 231-4315:
No such thing has ever been found in the brain. No one has ever found anything like a neural storage of learned numbers.
Never-Found #4: Non-genetic Token Repetition in Brains
Tokens are used in a repetitive manner when information is stored. In digital storage systems the tokens are electronic marks that are the equivalent of 1 and 0. In books the repeated tokens are letters. In photos the repeated tokens are pixels, tiny dots of color. There are many possible ways to represent things, using different systems of tokens.
The only token repetition ever discovered in brains is the token repetition occurring in DNA, found in almost all cells in the body. That is genetic token repetition, in which (following the coding scheme of the genetic code) certain combinations of nucleotide base pairs represent particular amino acids.
Except for this genetic token repetition which occurs in almost all cells (such as cells in the fingers and the feet), no token repetition has ever been discovered in the brain. The importance of this cannot be underestimated. It suggests very strongly that learned information is not stored in the brain.
There are all kinds of "secret codes" that we can imagine a brain using to store information. But such codes all require massive amounts of token repetition. For example, the Morse Code is a way to transmit information by using a series of dots and dashes. The Morse Code can also be used to store information. But whenever such a code is used, there is always massive amounts of token repetition. For example, three dots means "S" in the Morse Code, and three dashes means "O" in the Morse Code. When you cannot find any token repetition despite the most careful examination, you can be pretty sure information is not being stored.
Never-Found #5: Addressing in Brains
Addressing is some system whereby unique spatial positions have unique identifiers. We are all familiar with one type of addressing: the unique addresses of houses in a city. Addressing is also used in books, where each page has a unique address (its page number). Addressing is also used by the Internet. The URL of a web page is a unique address allowing browsers to quickly find one particular page among all the pages of the internet. Addressing is also used on digital devices such as smartphones and computers. On my computer a file name combined with a full path name makes up a unique address for a file. For example, on my computer a particular file has the unique address of c:\windows\write.exe.
No one has ever discovered any type of addressing system used by the brain to identify particular cells or synapses. Neurons do not have neuron numbers or neuron names or neuron addresses, and synapses do not have synapse numbers, synapse names or synapse addresses. This is troubling, because it means that although humans are able to retrieve obscure little-remembered information instantly, the brain does not use one of the three things that enable rapid information of physically stored information: addressing, sorting and indexing. But what about the other two? They are discussed next.
Never-Found #6: Sorting in Brains
Sorting is something that can help allow fast information retrieval. An example is found in books. Books have unique page numbers, but you would not be able to use the index of the book to find information quickly if the pages of the book were not sorted in numerical order. Another type of sorting that facilitates fast information retrieval is alphabetical sorting. An example of such sorting can be found in a one-volume encyclopedia. It is easy to find information quickly on any topic, because there is an alphabetical sorting of the articles. Similarly, if you have a large file cabinet filled with 100 or more manilla folders, you can find some desired information quickly if the folders are arranged in alphabetical order.
No one has ever discovered any type of physical sorting in a brain. The physical arrangement of the brain makes a sorting of neurons impossible and a sorting of synapses impossible. Once a neuron exists, it is attached to so many synapses that it cannot move around in the brain. Synapses are also stuck in their current position, and cannot move or be moved around in any way that would allow sorting. In this sense both neurons and synapses differ from blood cells, which can move around from place to place in the body.
Never-Found #7: Indexing in Brains
Indexing is something that can facilitate the fast retrieval of information. Indexing is used at the back of books. Indexing is also a crucial part of database systems that allow a fast retrieval of information. For indexing to be used effectively, a system must have both addressing and sorting. For example, you can index a book to allow fast retrieval of subject matter, but the book must have page numbers, and the page numbers must be in numerical order.
There is no sign of any indexing in the brain. This should as no surprise, given that effective indexing requires both sorting and addressing, neither of which exist in the brain.
Never-Found #8: A Place in the Brain for Permanently Storing Memories for Decades
Never-Found #9: A Position Focus Mechanism in the Brain
- A physical book can be opened to only one pair of pages. When a reader reads that book, his eyes can focus on only one line at a time. When the reader focuses on a particular line, position focus is achieved.
- When a film is run through a film projector, only one frame at a time can be in front of the light that passes through the film. In such a way, position focus is achieved.
- In the disk of a computer hard-drive, there is a read-write head that moves around to read particular parts of the disk. At any time, the head is above one particular spot of the disk, and position focus is achieved.
- The needle of a phonograph can only be resting on on one little spot on the phonograph record. Whenever that needle rests on one particular spot on the record, position focus is achieved.
- The current tab of a web browser will always be on one particular web page, with a URL displayed at the top of that tab. With such a rule, position focus is achieved, with the URL being a particular position within the vastness of the Internet.
- You can name a variety of planets, such as Earth, Venus and Mars.
- Pondering one of those planets (Earth), you can name a variety of continents existing on that planet.
- Pondering one of those continents, you can name a variety of countries on that continent.
- Pondering one of those countries (the United States), you might be able to name a variety of the 50 states that make up that country.
- Considering one of those 50 states (New York state), you might be able to name particular cities in that state (such as Albany and New York City).
- Thinking of New York City, you might be able to name the five boroughs of that city.
- Pondering one of those five boroughs (Manhattan), you might be able to name a variety of streets in that borough.
- Pondering one of those streets (such as Broadway), you might be able to name a variety of buildings on the selected street.
- Pondering one of those buildings (such as a particular Broadway theater), you might be able to name actors that are starring in some play now running in such a building.
- Pondering such an actor, you will be able to name particular parts of his body such as legs, brain, heart, pancreas, kidneys, arms and so forth.
- Pondering one of those parts of the body (such as an eye), you might be able to name particular parts that make up that part, such as the lens, retina and cornea that make up an eye.
