When we are children we have open minds. Our minds are impressionable and limitless.
That magical feeling you got when you watched science fiction (believing it could be real) or Peter Pan, flying (knowing you could do it with some practice) is the young conscious mind at work.
The young conscious mind is not-so set in its ways, not so judgmental, and not so adverse to new, and perhaps, illogical ideas.
At this point in our young life, very few systems exist to curb our actions and thoughts beyond what our environment has told us thus far (depending on age and experience, possibly very little).
Along with this lack of thought methodology you have negatives (or are they?) because learning things like ‘fire burns’ or ‘electricity shocks’ can be useful and, of course, have been helpful in your survival.
Intelligence is your guide
Intelligence is partially structural, or made up of many systems to help test life, to learn. Systems measure things, restrict things, guide you in learning, and help you feel solid and grounded in knowing them.
Imagination is non-linear and can help surpass those ‘intelligent’ systems. We use our imagination to search for something better, though we may or may not return something useful all of the time.
Imagination sets you free
Freedom of thought can help break through inaccurate or out-dated systems. It can help you deal with complex thoughts and feelings on death and life itself, and it’s meaning.
Both imagination and intelligence are necessary to development of the mind. One could not have a sense of progression without having a system to gauge the process in which you measure your success.
In searching for this meaning of existing or understanding of the mind, I’ve yet to truly ‘know’. These are the thoughts and ideas that flow through my brain, driving neurons and sparks of electricity to collide.
