If

[Little Rik]

In this way the brain is in total command according to what i do understand from your statement.

You seem to be jumping to conclusions. The brain is never idle. This is a fact. If you required the "I" for the brain to function, you'd be dead, since nearly all of your vital functions are controlled unconsciously. Did you know that we dream every night, even though we may not remember any of those dreams? Where is the "I" when your brain is off in dreamland, fully free of your conscious direction? Who is this other spirit person, rampaging through your defenseless mind night after night, having its way with your psyche while the "I" is nowhere to be found?

A car can be left idle with the engine on but it is not moving anywhere UNTIL the driver pop in and put it into gear and drive away.
The brain works in the same way.
It can well be into an unconscious dream but UNTIL the I decide to make it move nothing really happen.
So it is the I that decide not the brain.
Sorry mate for disappointing you.

May i ask you what the I means to you if anything?
Once i know what you think than i will be able to explain you why.

I = the nominative singular pronoun, used by a speaker in referring to himself or herself.
EXAMPLE: "I am writing this post."

Exactly as i thought.
Considering that we are talking about whether the brain and the I are the same thing or they are two separate entity that does not mean anything to you.
That is why i point out by putting a big I that according to me the I is the decider not the brain.
