You don’t understand the model.
I am saying there is a difference between 2 example patients.
Patient A is a human fetus, 8 weeks old. It is currently alive in it’s mother. It’s never manipulated it’s environment and observed the results, and thus the amount it can realistically have learned is little to nothing. It also is incapable of exhibiting any complex behavior and never has.
Patient B is a coma patient, 20 years old. This person was an average high school and average high school student up until a severe auto accident. MRIs reveal that patient B’s brain is damaged but most of it is still there. In addition, the damage is to one side, and the brainstem, spine, and cranial nerves are mostly intact. There is a 5% chance patient B will awaken, based on examples of similar coma patients.
Both A and B are vegetative beings. They cannot do much that is interesting. However, I am saying patient B has this variable *, the information learned in their life and their personality.
I don’t need to do anything to prove they have *, but point in a general direction of information theory, neuroscience texts, etc. It is self evident that B’s complex behavior, when they were able to function, requires stored information in their mind. In addition, since I can show an MRI scan showing that most of B’s brain is still present, the * still exists.
In fact, I can preserve the maximum * by perhaps waiting until enough time has passed that the chance of reawakening is under 1%, then preserve B’s brain in a way that preserves all of the fine nanoscale structures at each synapse. I would argue that B’s brain on a shelf or in a freezer is still a person. (and the rest of their body, whether it was donated or incinerated, is not a person, just some spare parts)
While the fetus is not. Physical chemistry has trouble showing how much heat an object has directly, because you can only measure temperature directly, not enthalpy.
Similarly, present day humans can’t just scan or copy a living brain and grab all the important data from it. So you can’t trivially show how much * exists. But you can show when there was no data input to generate any nontrivial amount of *.
Since the fetus cannot manipulate it’s environment, it cannot isolate more than a negligible amount of *. I could explain why but this post is already too long.
