When you look out of the window, you think that you see an image with your eyes, as this is the way that you have been taught to think. However, in reality this is not how it works, because you do not see the world with your eyes. You see the image created in your brains. This is not a prediction, nor a philosophical speculation, but the scientific truth.
This concept can be better understood when we realize how the visual system operates. The eye is responsible for transforming light into an electric signal by means of the cells in the retina. This electrical signal reaches the sight center in the brain. The signals create the vision you see when you look out of the window. In other words, the sights you see are created in your brain.
You see the image in your brain, not the view outside the window. For example, in the picture shown on the right hand side, the light reaches the eyes of the person from outside. This light passes to the small sight center located at the back of the brain after the cells in the eyes transform it into electrical signals. It is these electrical signals which form the picture in the brain. In reality when we open the brain, we wouldn't be able to see any image. However, some kind of consciousness in the mind receives electrical signals in the form of an image. The brain perceives electrical signals in the form of an image, yet it has no eye, eye cells, or retina. So, to whom does the consciousness in the brain belong?
The same question can be asked about the book you are reading now. The light coming to your eyes is converted into electrical signals and reaches your brain, where the view of the book is created. In other words, the book you are reading right now is not outside you, it is actually inside you, in the sight center in the back of your brain. Since you feel the hardness of the book with your hands, you might think that the book is outside you. However, this feeling of hardness also originates in the brain. The nerves on your fingertips transmit electrical information to the touch center in your brain. And when you touch the book, you feel the hardness and intensity of it, the slipperiness of the pages, the texture of the cover and the sharpness of the edge of the pages, all within your brain.
In reality however, you can never touch the real nature of the book. Even though you think that you're touching the book, it is your brain that perceives the tactile sensations. In addition, you do not even know if this book exists as a material thing outside of your brain. You merely interpret the image of the book within your brain. However, you should not be tricked by the fact that a writer wrote this book, the pages were designed by a computer and printed by a publisher. The things that will be explained in due course will show you that the people, computers and the publishers in every stages of the production of this book are only visions that appear in your brain, and you will never know whether or not they exist outside of your brain.
We can therefore conclude that everything we see, touch and hear merely exists in our brains. This is a scientific truth, proven with scientific evidence. The significant point is the answer to the question asked above, which this scientific truth has led us to ask;
Who is it that has no eye, but watches sights through a window in our brains and enjoys or becomes anxious from these sights? This will be explained in the following sites.
We acknowledge that all the individual features of the world are experienced through our sense organs. The information that reaches us through those organs is converted into electrical signals, and the individual parts of our brain analyze and process these signals. After this interpreting process takes place inside our brain, we will, for example, see a book, taste a strawberry, smell a flower, feel the texture of a silk fabric or hear leaves shaking in the wind.
We have been taught that we are touching the cloth outside of our body, reading a book that is 30 cm (1 ft) away from us, smelling the trees that are far away from us, or hearing the shaking of the leaves that are far above us. However, this is all in our imagination. All of these things are happening within our brains.
At this point we encounter another surprising fact; that there are, in fact, no colors, voices or visions within our brain. All that can be found in our brains are electrical signals. This is not a philosophical speculation. This is simply a scientific description of the functions of our perceptions. In her book Mapping The Mind, Rita Carter explains the way we perceive the world as follows:
Each one [of the sense organs] is intricately adapted to deal with its own type of stimulus: molecules, waves or vibrations. But the answer does not lie here, because despite their wonderful variety, each organ does essentially the same job: it translates its particular type of stimulus into electrical pulses. A pulse is a pulse is a pulse. It is not the colour red, or the first notes of Beethoven's Fifth-it is a bit of electrical energy. Indeed, rather than discriminating one type of sensory input from another, the sense organs actually make them more alike.
All sensory stimuli, then enter the brain in more or less undifferentiated form as a stream of electrical pulses created by neurons firing, domino-fashion, along a certain route. This is all that happens. There is no reverse transformer that at some stage turns this electrical activity back into light waves or molecules. What makes one stream into vision and another into smell depends, rather, on which neurons are stimulated.1
In other words, all of our feelings and perceptions about the world (smells, visions, tastes etc.) are comprised of the same material, that is, electrical signals. Moreover, our brain is what makes these signals meaningful for us, and interprets these signals as senses of smell, taste, vision, sound or touch. It is a stunning fact that the brain, which is made of wet meat, can know which electrical signal should be interpreted as smell and which one as vision, and can convert the same material into different senses and feelings.
Let us now consider our sense organs, and how each one perceives the world.
It's Not Our Eyes That See, It Is Our Brain
Because of the indoctrination that we receive throughout our lives, we imagine that we see the whole world with our eyes. Eventually, we usually conclude that our eyes are the windows that open up to the world. However, science shows us that we do not see through our eyes. The millions of nerve cells inside the eyes are responsible for sending a message to the brain, as if down a cable, in order to make "seeing" happen. If we analyze the information we learned in high school, it becomes easier for us to understand the reality of vision.
The light reflecting off an object passes through the lens of the eye and causes an upside-down image on the retina at the back of the eyeball. After some chemical operations carried out by retinal rods and cones, this vision becomes an electrical impulse. This impulse is then sent through connections in the nervous system to the back of the brain. The brain converts this flow into a meaningful, three-dimensional vision.
For example, when you watch children playing in a park, you are not seeing the children and the park with your eyes, because the image of this view forms not before your eyes, but at the back of your brain.
Even though we have given a simple explanation, in reality the physiology of vision is an extraordinary operation. Without fail, light is converted into electrical signals, and, subsequently, these electrical signals reveal a colorful, shining, three-dimensional world.
