Haise and Kaneki Mind VS. Soul
So everybody’s asking the question. Will Haise’s personality survive the return of Kaneki’s memories? I think that depends on whether he exists with Kaneki’s Mind alone or is part of Kaneki’s soul. And depending on which theory of existence Ishida is using.
The theory of the mind is that people do not exist on a higher level, that they are merely the synapses of thoughts and electrical impulses created in a properly operating brain attached through memories.
Under this theory I believe that the damage done by taking IXA through the head created a disconnect between the Kaneki and his memories, and in the blank space as the brain reconstructed it’s self nearly perfectly due to ghoul healing it attempted to recreate itself by creating in a way a new existence.
The new existence (Haise) is attempting to make new connections and use the surviving reflexes, language centers etc. the brain already has while making new memories and forming new perceptions about the world. Forming new dendrites you know.
After all it’s not odd for people with amnesia to even develop seemingly different personalities and even voices.
The funny thing about memories and memory loss though is that memories rarely disappear unless the places the memories are contained achieve brain death. The reason please get with amnesia usually get amnesia is by the connections to the places the memories are stored being damaged.
In that case it is safe to assume that as the ghoul healing enabled brain was slowly healing it’s finite connections might be being remade and the old existence (Kaneki) is in a way waking up.
Perhaps the connection between the two existences is being triggered by something. With amnesia often the way someone regains memories is through finding some still existing connection, sometimes a smell or even a taste, or in Haise’s case his own original name.
Under this theory Haise’s fear of losing himself or his memories would be very real. If Kaneki’s personality took over it could mean disconecting all of Haise’s existence by cutting of his connections from control and causing him to “die’, as Kaneki’s regained control of the brain.
Think of it like this, you plant a flower in a pot and over time it seems to die, so in the seemingly empty soil you plant another seed, this new flower starts to thrive but all of the sudden the old one springs up again and the two have to start struggling for resources and eventual one’s roots straggle the other out.
The Soul theory is a bit simpler and rests under the idea that a person’s mind is not simply a collection of connected neurons but a separate entity, a “soul” influenced by the experiences of life.
In that case Haise is simply Kaneki as he might have ended up not going through a lot of the things he did in life. In this instance Haise is simply amnesiac Kaneki.
So then who is the Kaneki in the hallucinations?
The Kaneki Haise sees could simply be that a hallucination, the culmination of bad memories from being tortured and the bad things he did and disturbing feelings he had from being Centipede. His mind can’t make sense of them or senses danger and is attempting to keep them out. Again these memories are being triggered by some stimuli most obviously his name, but he’s rejecting them.
On the other had the Kaneki persona could be a split in the personality.This would make sense seeing Kaneki’s previous behavior of having his black and white haired self talking to one another.
Haise’s personality would be the little he can subconsciously remember such as his love of books and remembrance of others kagune, plus what he has learned since being stabbed and the base parts of his personality.
Kaneki’s separate personality is caused by the slow return of past memories. Haise’s mind is attempting to protect it’s self and so whenever a line is crossed out of fear or worry, or when a triggering thing is said it attempts to slip into the other personality (Kaneki) to protect the softer Haise side of the mind from it’s own madness.
There are a few possibilities for this scenario, either both the Haise memories and the Kaneki memories could meld to together and make a whole personality. Or the Kaneki or Haise side of the personality could become dominate, or there could be a situation where he snaps back and forth.
