Objectivity proceeds from two assumptions, as I have previously pointed out. I can only assume at this juncture that you are simply unable to examine the notion that this second assumption exists, which is fair enough.
Give it up, Nick, you're simply wrong on this.
You are saying that you have never experienced thoughts?
Non-sequitur.
As I said, the machinery of the brain generates experiences. You don't experience the machine.
This is one aspect of personal identity, yes, the belief that the body belongs to someone. As you say, the capacity for the human brain to believe in limited selfhood, that it has the necessarily neurological bits and bobs to do so, is obviously essential. However, this does not mean that limited selfhood exists, merely that the brain is capable of believing that it does. This is what gives humans their immense power to transform the world - the capacity to believe that they have personal identity.
You are conflating two different points that you raised yourself. The ability to conceive of the limited self is not proof of the limited self; that proof comes from experimenting with the real world. The ability to conceive of personal identity, however, is proof of the existence of personal identity.
If you can ask the question "Do I have personal identity?", the answer is necessarily
yes.
I'd say they developed the notion of personal selfhood through the need to survive.
Or to put it another way: The personal self is so real that pretending it doesn't exist is fatal.
I will be happy to read the evidence once you have it.
Read up on alien hand syndrome now. It's more interesting, better studied, and by itself conclusively shows that personal identity is brain function.
Is there not a certain flow of thoughts involved in you writing your reply? Can you see that without this flow there would be no reply? Is it possible you could stop for a moment and ask yourself - how do I know that this is my thought, not that it might be someone elses, but that it has possession at all? It's all just thoughts. The entire personality is constructed and maintained solely through thoughts and the phenomenon of identification with thought. If you don't believe me, just sit and watch it happening!
We
observe that our thoughts are our own, Nick. We can test this and confirm that no-one else is privy to our thoughts, nor are our thoughts shared with anyone else.
We can erase individual memories. We can and do voluntarily render ourselves unconscious. We can track the process of recognising our mother's face millisecond by millisecond as waves of signals pass through the brain. We can chemically and electrically trigger pain, pleasure, psychosis and seizures. It's all of it brain function.
Again, no assumption required, you just need to pay attention.
