Why can't the "mind" just be the brain?
Build a robot capable of understanding himself and he will have the sense the he is only him from the perspective of inside his components, seeing through his inorganic eyes. The feeling of identity is the limitation of understanding (software) to the hardware its confined in.
How do you know? What is it about certain ordered collections of matter that creates a sense of self-awareness?
I see no reason why I shouldn't think that software in hardware that knows the truth that it is software in hardware, wouldn't be self aware. What more to self awareness is there then knowing about one's own physical existence?
You do not rule out freewill, because it allows individual decisions?
Sorry, I didn't express that very well. By "the explanation for it" I meant the explanation for self-awareness.
Why would either freewill or self awareness require the other?
Back to the robot. Input goes to the data processing sensors of the brain and the software determines a course of action and acts. Determining the action with respect to sensation is consciousness. A calculator could be said to be conscious of numbers, but it wouldn't understand the concept of numbers or the concept of the calculator without additional comprehensive ability.
I don't think a calculator is conscious of anything, at least not in the sense that we are conscious of ourselves. A calculator just has electrical charge moving around inside it, and it's an enormous leap from saying that something contains moving charges to saying that it is actually aware of something.
When I say aware of things, I'm talking about what input it is built to be sensitive to and act upon even if it doesn't have proper context.
When it can process information with respect to itself. When relevant information regarding actions includes itself.
But why does that particular information generate self-awareness? It's still just moving electrical charges; the fact that those charges represent something when interpreted a certain way shouldn't make any difference as to whether the machine is conscious or not.
I consider awareness to be a continuum, and only being aware of electrical signals is very limited consciousness. If it understood what they were, what they meant, etc. it would be more conscious because it can give it context. We humans just have more information about what input we take in and that our minds are processing the data. We the software, know about the existence and basic processes of the software. A calculator doesn't have any context to its input. Similarly, it doesn't have any knowledge of itself, and doesn't have any sensory devices or neural pathways to become aware of itself.
A calculator is not aware of space or time, so the space it occupies is also unnoticed. Its entire understanding of everything comes down to data it knows how to process but doesn't understand. A robot does recognize it takes up space and has a physical existence. A calculator doesn't know it exists. Self awareness allows for new paradigms of behavior because it adds new elemental variables.
A robot does recognize that it has physical existence, but that's not what I'm talking about when I speak of consciousness. What I am talking about is the feeling of being awake, of being aware of things.
Does a robot not have the sensation of awareness?
Being able to process information and actually being conscious of that information are two very different things - the subconscious mind is an excellent way of illustrating this.
I'd say that being consciousness of information is having a better understanding of the information and its context.
Subconscious processing is just lower levels of processing that the mind software found in the processes isn't built to interpret or explore itself. Same way a calculator can process data without having or needing knowledge that it is processing. If it could see its own background processes, it would be much more self aware.
Our brains can only handle self thought so much considering the limits of efficiency on the brain. If every neuron on its own was able to think about a single neuron, then no processes of the brain would ever be hidden.
Also, by dedicating processes of the brain that are built specifically for other functions by not thinking about those things in the here and now, we should be able to reach into our subconscious thoughts. Hypnotism does just that.
