Closing one eye causes the third dimension to flatten, making depth very difficult to determine as the ‘stereoscopic’ effect is lost. Visual reality is altered to a state where estimating the distance of objects becomes difficult without a scale of some sort to measure it by. Our personal beliefs can have as much impact on the senses and probably where the term "One eyed", which encompasses the individual’s subjective view of reality, originates.
When forming, our brain can be thought of much like a tree. The genetic information for the formation of the genus is the basic coding for how the tree should grow, but the environmental elements are what ensures the tree’s formation. Each branch is formed in the ultimate position to other branches so it can receive maximum nutrients and sunlight to its leaves. Our brain paths form and operate in the same way, as we experience each moment, we use the most efficient routes to interact with the rest of the brain and the environment, sometimes forming new paths and slightly changing our structure.
Recent studies have theorised that the firing of neurons within brain paths produces an electromagnetic charge and this varying energy field is conscious itself. (1) It is the combination of differing paths and levels of chemicals within the brain which constitutes the being’s personality at any given moment. ‘Decisions’ are made to obtain/retain the optimal conscious level within the brain by the brain itself, conscious being a by-product, rather than the source, of a decision. Supporting this, neuro-imaging shows that brain paths activate an average of half a second before the subject consciously acts upon the impulses.
Belief is formed through a combination of education and experience. The judgement of another’s character is an instinct to survive. Throughout society’s evolution the need to categorise others into a demographic group has accumulated into mostly illogical, elitist judgements and we are fractalised into increasingly smaller groups. It is humanity’s common belief that each individual chooses what to believe and this fallacy drives so much disharmony among mankind. Probably the biggest source of disharmony among man is strong belief structures.
Another study reflects how strongly stereotypical belief can influence our reality. A group of students who received the same result on an exam were split into two groups. Group A were told they were to act as college professors, imagining what they would wear and taking on the persona. Group B were told to act likewise as football hooligans. When the two groups were subjected to a similar exam as the first, Group A scored quite high, whereas Group B quite low. (2) In a similar study, students primed to act as politicians wrote long winded essays. (3) We perform in direct relation to what we believe ourselves to be.
Without belief our existence would be intangible and insecure, communicating to others would be made difficult as nothing said could be communicated as ‘fact’. Yet, most facts are subjective, what is fact to you is not necessarily reality to someone else. In the past, society believed the Earth to be flat and if you were to sail out into the ocean you would eventually fall off the edge. Had everyone continued to believe such, society would have stagnated. Looking back only a few hundred years into a history we find society’s values and beliefs appear ignorant, archaic, immoral and brutal. People were murdered in horrific ways in the name of ‘Faith’ and, sadly, today such ignorant and immoral behaviour is broadcast to us up to the minute. Much has changed, but we, as a society, are yet to evolve past this ultimate ignorance.
