Digitally Enhanced Performances: The Actors Who Received a Virtual Touch-Up

 The world we live in is an illusion of our brains

I hesitated a lot before writing this topic because it differs from the previous topics. Yes, the content and ideas of this topic made me rethink my view of this world. Is it real or just an illusion? Perhaps many of you will not share this idea, which appears, at first sight, to be extremist. It is unreasonable, but once you begin to absorb scientific ideas and facts, you will realize that the world is not as it appears but as our minds imagine it for us.

The vision process takes place in several successive stages. The light beam that an object emits to the eye crosses the iris of the eye and is reflected on the retina at the back of the eye. The retinal cells emit electrical signals transmitted by the optic nerve to a very small spot located at the back of the brain, a dark spot that never sees light. Let us now summarize this seemingly normal process, when we say that we "see", we actually see the effect of the impulses that reach our eyes and are sent to the brain after converting them into electrical signals, meaning that when we say that we "see", what we see in reality is nothing more Being electrical signals inside the brain.

The person who eats a fruit does not actually encounter the fruit itself, but rather the image that the brain perceives of it. The body that represents the “fruit” consists of electrical signals specific to the shape, taste, and smell of this fruit. If the optic nerve that extends to the brain is cut off, the image of the fruit will suddenly disappear. The same thing happens if we cut the olfactory or taste nerve. In simple words, the image of the fruit is nothing but the brain's interpretation of the electrical signals, and as you read these lines, you are not as you think sitting inside the room or cafe, but rather the room or cafe is what is inside the brain in the center of vision.

 The above applies to all senses. When you think that you hear the sound of the phone in the next room, you are in fact only interacting with the electrical signals transmitted by the auditory nerve. A brain is a quiet place that does not interact directly with sound waves. The external world that we perceive with our senses is nothing but “electrical signals” that reach the brain. We live without realizing the mistake that we have fallen into, assuming that what we see is the origin of the material that makes up the external world. The brain is responsible for interpreting and giving meaning to the signals that are supposed to represent the outside world. Symphony is just sound waves and colors are just wavelengths of light. There are no colors in the outside world. Neither an apple is green nor a blue sky. We see it like this because our brain interpreted it. the shape. The external world depends entirely on the means of perception.

A simple defect in the retina may lead to color blindness, some people see blue as green and others see red as blue, and a category sees all colors only in shades of gray, and in this case, it does not matter much whether the external body is actually colored or no. The material facts that we have built so far lead us to the following conclusion: “What we see, touch, hear and perceive as “material”, “the world” and the entire “universe” are electrical signals received by the brain, we cannot at all reach the reality of the matter. outside our minds, but we can see, hear and taste the "warming world" as it is formed in our ointments.

   And we should not forget to mention that animals see and hear in different ways. Some see with the help of infrared or ultraviolet rays, and the bat draws a sound image using the resonant sound, so whoever owns the real picture of the world is humans, animals, or perhaps insects.

And FREDRICK VESTER says, "Science has proven that man is just an image, that all our experiences are temporary and deceptive, and that the entire universe is nothing but a fantasy." The well-known thinker Berkeley discusses, "In the beginning, the common belief was that colors and smells "do exist in the external world, but these views were later abandoned, as it was proved that their existence depends on our senses." I do not fail to refer to the issue of dreams, which often deceives us, so we fear, tremble, run, laugh, and suffer, as if we are experiencing events and meeting people, and this is nothing but a world formed by our minds.

Can we be deceived? naturally. But there is a practical argument in favor of relying on the inter-subjective agreement as the basis of the truth. Even if everyone is deluded, we still need to explain our impressions. The illusion, after all, is wholly real; It is the interpretation of illusion that can mislead us. If I saw a smooth blue patch in the desert, I might misinterpret the blue patch as an oasis, but that doesn't mean my impression is not real. I see something real: not an oasis, but a refracted image of the sky. So, even if we are all just projections of a computer simulation, like the Matrix, the simulation itself has a structure that gives it a form of reality, which is our reality, the reality we need to be able to navigate.

The fact that we can infer that certain sensory perceptions are wrong indicates the existence of a hierarchical structure of mind and perception; We have not only sensory perceptions but inferences related to these inferences (compare with the term: metacognition). The meanings involved in the idea of ​​self-awareness are clear. That's why people like Allan Hobson are fascinated by pure dreams. It provides us with an exquisite condition suitable for clinical testing that enables us to compare situations in which the reality of a dream is represented as a reality, with those situations in which a person is aware of the fact that it is a dream. From a neuroscience point of view, this appears to depend on the activity of the frontal lobe, which again points to the arboreal nature of this remarkable organ. (ie: the mind that produces fantasies that are compared with reality).

The idea that perception is merely hallucinations based on sensations is somehow weakened by the fact that we can, in certain cases, perceive that our perceptions are wrong.

Our world is a very strange place, sometimes there are many things that we think are normal, but they may be unusual in the eyes of other people, and they may even find them ugly. But in the end, there are things that we all agree on ugly and hateful because they are inhuman and unjust to an unimaginable degree.
