First some context. There's a well known study, which has been replicated and conclusive about the results, that shows that some decision are made some seconds before the person is conscious about making the decision.
The study in a nutshell could be described as asking a person to choose between moving its right hand or left hand, and asking him/her to record exactly what time it was when she decided what option to choose. Using fMRIs has been shown that even though the person say that his/her decision was made at time X, analysis of the brain function shows that such decision was already decided as far as 10 seconds before. (For more info just Google: 'fMRI and free will').
My point is: Ok, it was already decided 10 seconds ago. I'm not going to put that in doubt, it's just a hard evidence. What this shows is that it was already decided, but the question is then: Who decided it?. There are two options: It was me, or it wasn't me (i.e: some chain of causality of nature). I just want to explore the options of being me doing that decision.
I could say: Ok, it's true that was already decided, but who can say that it wasn't me in some sense?. As I approach the question I see two options. It was my conscious mind or my unconscious mind.
Clearly, it wasn't my conscious mind, just for the simple reason that in the experiment they asked me to record the time when I was conscious of my decision. And being proved that the decision was made before, simply shows that at least it wasn't a conscious decision.
So I guess I could claim that, it was me making the decision but my unconscious me. How can this be disproved?.
To show that I must show that I can't take credit for my unconscious. If my unconscious thoughts aren't my responsibility (to take credit for), why should mathematicians be credited for 'eureka' insights that appear while waking in the street without thinking of their problems consciously?
I'm having a hard time on this point. I'd really appreciate some insights!
Edit: Just some interesting reference with a short video.
