IT IS A SCIENTIFIC FACT THAT THE
INTO EXISTENCE IN OUR BRAINS
you take a look at the room in which you are sitting, what you
see is not the room outside of you, but a copy of the room that
exists in your brain. You will never be able to see the original
room with your sense organs.
All events and objects that we encounter in real life-buildings,
people, cities, cars, places-in fact, everything we see, hold, touch,
smell, taste and hear-come into existence as visions and feelings
in our brains.
We are taught to think that these images and feelings
are caused by a solid world outside of our brains, where material
things exist. However, in reality we never see
real existing materials and we never touch real materials.
In other words, every material entity which we believe exists in our
lives, is, in fact, only a vision which is created in our brains.
This is not a philosophical speculation. It is an empirical
fact that has been proven by modern science. Today, any scientist
who is a specialist in medicine, biology, neurology or any other field
related to brain research would say, when asked how and where we
see the world, that we see the whole world in the vision center located
in our brains.
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
we perceive is specially recreated for us in our brains. Therefore,
when we say, "We are aware the world around us," we
are talking about copied images of colors and shapes, of sounds
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 percetions. 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.
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.
It's Not Our Eyes That See, It Is Our Brain
CEO of a company might consider the company building, his car
in the parking lot, his house by the beach, his yacht, and all
the people who work for him, his lawyers, his family, and his
friends to be outside of his body. However, all of these things
are merely visions formed in his skull, in a tiny part of his
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,
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. R. L. Gregory, in his book Eye and Brain: The Psychology of
Seeing, acknowledges this significant fact, and explains this incredible
We are given tiny
distorted upside-down images in the eyes, and we see separate solid
objects in surrounding space. From the patterns of simulation on the
retinas we perceive the world of objects, and this is nothing short
of a miracle.2
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.
All of these facts lead to the same conclusion. Throughout
our lives, we always assume that the world exists outside of us. However,
the world is within us. Although we believe
that the world lies outside us, it is in the smallest part of our
brain. For example, the CEO of a company might consider the company
building, his car in the parking lot, his house by the beach, his
yacht, and all the people who work for him, his lawyers, his family,
and his friends to be outside of his body. However, all of these things
are merely visions formed in his skull, in a tiny part of his brain.
He is unaware of this fact and, even if he knew, would
not bother to think about it. If he stood proudly next to his latest-model
luxury car, and the wind blew a piece of dust or a small object into
his eye, he might gently scratch his itching, open eye and notice
that the "material things" he saw moved upside down or to
the sides. He might then realize that material things seen in the
environment are not stable.
What this demonstrates is that every person throughout
his or her life witnesses everything inside their brain and cannot
reach the specific material objects that supposedly cause their experiences.
The images we see are copies in our brains of the objects that we
assume to exist outside of us. We can never know to what extent these
copies resemble the originals, or whether or not the originals even
Although German psychiatry professor Hoimar Von Ditfurth
is a materialist, he acknowledges this fact about scientific reality:
No matter how we
put the argument, the result doesn't change. What stands before us
in full shape and what our eyes view is not the "world".
It is only its image, a resemblance, a projection whose association
with the original is open to discussion.3
For example, when you take a look at the room in which
you are sitting, what you see is not the room outside of you, but a
copy of the room that exists in your brain. You will never be able to
see the original room with your sense organs.
How Can A Bright And Colorful Image Appear In Your
Every person throughout his or
her life witnesses everything inside their brain and cannot
reach the specific material objects that supposedly cause
There is another point that should not be neglected;
light cannot pass through the skull. The physical area in which the
brain is located is completely dark, and light cannot possibly penetrate
it. However, incredible as it may seem, it is
possible to observe a bright and colorful world in this total darkness.
Colorful natural beauty, bright sights, all the tones of the
color green, the colors of fruits, the designs of flowers, the brightness
of the sun, people walking on a busy road, fast cars in traffic, clothes
in a shopping mall-are all created in the dark brain.
Imagine a barbecue burning in front of you. You can sit
and watch the fire for a long time, but throughout this entire time,
your brain never deals with the original of light, brightness or heat
from the fire. Even when you feel its heat and see its light, the inside
of your brain remains dark and maintains a constant temperature. It
is a profound mystery that, in the darkness, the electrical signals
turn into colorful, bright visions. Anyone who thinks deeply will be
amazed by this wondrous occurrence.
Light Is Also Composed In Our Brain
While discussing what science has discovered about vision,
we mentioned that the light we receive from the outside gives rise
to some movements of the eye cells, and these movements form a pattern
from which our visual experience emerges. However, there is another
point that we need to make: Light, as we perceive
it, does not reside outside of our brain. The light we know and understand
is also formed within our brain. What we call light in the
outside world, which is supposedly outside our brains, consists of
electromagnetic waves and particles of energy called photons. When
these electromagnetic waves or photons reach the retina, light, as
we experience it, begins to come into existence. This is the way light
is described in physical terms:
The term "light"
is used for electromagnetic waves and photons. The same term is used
in physiology, as the feeling experienced by a person when electromagnetic
waves and photons strike the retina of the eye. In both objective
and subjective terms, "light" is a form of energy coming
into existence in the eye of a person, which a person becomes aware
of through the retina by the effects of vision.4
Consequently, light comes into existence as a result
of the effects that some electromagnetic waves and particles cause
in us. In other words, there is no light outside our bodies which
creates the light we see in our brains. There is only energy. And
when this energy reaches us we see a colorful, bright, and light-filled
world. We can therefore conclude that everything we see merely exists
in our brains. This is a scientific truth, proven with scientific
Say: “What do
you think? If Allah made it permanent night for you till
the Day of Rising, what god is there other than Allah
to bring you light? Do you not then hear?”
