who feign ignorance of the fact that we can’t get in touch with the ex-
ternal world, that our experience is composed of perceptions felt in
our brain; and proceed not to inform people of the truth, even behav-
ing as if it did not exist. But ignoring the truth is no solution. Let us
examine this reality a little more closely.

What We Perceive As Outside Is Actually Inside Ourselves

Stimuli such as light, sound, smells, tastes and textures from ob-
jects assumed to exist in the external world are carried through
nerves to sensory centers in the brain. All these stimuli consist of
electric signals. During the process of sight, for example, light rays
(photons) radiating from the exterior world reach the retina at the
back of the eye, which transforms them through a series of processes
into electric signals. These signals are transferred along nerves to the
center of vision at the rear of the brain. Thus, the colorful, bright,
three-dimensional world is perceived within this center of only a few
cubic centimeters.
The same process also enables the other senses. Tastes are trans-
formed into electric signals by cells on the tongue’s surface. Smells
are transformed into electric signals by cells in the epithelium of the
nose. Special sensors lodged under the skin transform impulses of
touch (such as feelings of firmness or softness) into electric signals,
and a special mechanism in the ear transforms sounds in a similar
way. All these signals are sent to respective centers in the brain,
where they are finally perceived.
To clarify the point, assume you are holding a cup of coffee.
Receptors under your skin transform the cup’s hardness and heat
into electric signals and send them to your brain. Simultaneously, the
coffee’s strong smell, its taste and dark brown color all become sig-
nals sent to the brain. The clink when the cup touches the table is per-
ceived by your ears and sent to the brain as an electric signal. All
these perceptions are interpreted in the relevant brain centers, work-
ing harmoniously with one another. As a cumulative result of these
impulses, you sense yourself drinking a cup of coffee.
Anyone who sits in a room, watching television or dining with his
family, experiences a great miracle, even though he is unaware of it.
