It has always been a mystery well respected in the cognitive science area. The phrase of inspiration behind this colorful post is ‘What proof do you have that what you see is what lies right outside your eyes?’. It has been a phrase to toy with for philosophers, evolutionary biologists, atheists, scientists and some fascinated ( or fascinating? ) nerds like yours truly.

I chose the color criterion here to put forth my theory as it can be well debated over due to its explicit moot-ness. I also hold lack of proper knowledge a driving force behind this formulation. Let us assume three colors RED, XX and YY(heed the case). When a child is born, their first color recognition (among a plethora of other things) is through indoctrination. The mother shows a RED placard and tells child1 ‘Honey, this is XX color’. After a few repetitions the child has learnt his/her first color. Now every time the color RED appears in front of him, he says ‘XX’. Now let me introduce a new color ‘inter1′. The thought is as follows. When the RED color is shown to the child, his eyes and ergo his brain processes a color ‘inter1′ which is formed behind his eye (on the image) and relates to the indoctrinated memory and makes him spell ‘XX’ out.

Now let us consider child2. His mother shows him a RED placard and tells him ‘ Honey this is YY color’.Here, the intermediate color is ‘inter2′. So, when child2 is shown the RED placard, his brain processes the image formed behind his eye(inter2) and relates to the indoctrinated memory and he spells ‘YY’ out.

We see that the color shown to both the children is same – RED. But the intermediate colors differ in each child, as they are created by the brain.Now let us consider the case when child1 interacts with child2. Child1 shows a RED placard to child2 and says ‘This is XX’. Technically, child2 should refuse saying ‘No, this is YY’. But he doesn’t. Instead he smiles to agree and both children go play merry-go-round. So here is the extension of this theory. What if the hearing signals also have an ‘inter’ voice signal picked up by the brain from the ear drum? What if child2 ‘heard’ YY when child1 said XX and thus a consensus was reached?

If furthered, this would mean that the brain processing is completely different in each person’s head. Child1 looks at color RED and his brain processes ‘inter1′ and sends signal ‘xx’ to his vocal chords. He says XX. XX falls on the ear drum of child2, is sensed as a ‘yy’ signal which goes to the brain. The brain correlates ‘yy’ to ‘inter2′ which is confirmed from the optical signal received from the eye which forms the image of RED behind it. Thus child2 agrees.

I conclude that everything one sees, hears, senses is created by the brain and thus is totally different from what is ‘actually’ or ‘really’ happening outside one’s head. This theory has very loose roots but is considerable.Could it be true?

P.S. Watch alien movies where the vision of aliens is showed. It could arise some thoughts.
