1 - The patterns made at any brain ;
2 - The abilities of each brain in processing data and transfering it to different parts and at all we can say the functionallity of the brains .
There's a third thing you're missing:
3. Continuity that led up to what that brain is at that moment.
And actually, it's all three.
In order for a object to be classified as
the same object it must follow temporal continuity. A copied brain doesn't satsify this.
You are
you due to every event that has occured to you. A clone is you insomuch that it's existance can be traced directly back to you - the events that led to its existance can be traced back through yours -
however the clone's existance has no effect on
your existance, because there is nothing about the clone's existance that affects yours. That the clone exists or doesn't exist will in no way cause a change to you.
Whether the cloning is done with or without your knowledge and you are killed or not upon its creation has absolutely no effect on the fact that you and your clone are two unchangeably distinct individuals who exist in completely different places in spacetime. Let's say I make a clone of you perfect in every respect and then kept him in stasis. After his creation, I regularly update his brain with all the information you have gathered so that he remains a perfect likeness. At no point are you aware of his existance.
Is that clone you? If you die do you think you -
your mind - would experience 'waking up' in a strange laboratory? Or will it be someone else? From your argument, you're saying that no matter on location someone with the same pattern as you is you. Let me try another example then: very same scenario, except I'm now taking every impulse and brain pattern you ever had and printing it out on reams of paper.
Is that you? If I decided one day to put those in a brain, would you suddenly 'wake up' in that new body?
Okay, philosophically these might be sticky questions. I never put much stake in philosophy though. That's why I suggest thinking of things as blocks of wood. Philosophy applies an added "special" element to brains that is nonexistant. A brain is a piece of meat that happens to be important to us. If I copy all the atomic states in a block and then someday remake that block, is it the same block? Our natural intuition would say no, physics says no (even quantum entangled particles that have the same spin no matter where they are are considered different particles!), so I'm going to have to go with: no. If I make two blocks that are exactly alike are they the same block? Still no. If I take a block and carve it into a statue is it the same block? It's not in the same
form but it is still physically the
same block.
This is how we change our minds, not by making new blocks, but by carving them into something new.
