EVER THOUGHT ABOUT THE TRUTH?
as it is from light. Therefore, no matter how noisy it is outside,
the inside of the brain is completely silent.
Nevertheless, even the subtlest sounds are perceived in the
brain. The precision of this process is such that the ear of a
healthy person hears everything without any atmospheric noise
or interference. In your brain, which is insulated from sound,
you listen to the symphonies of an orchestra, hear all the noises
in a crowded place, and perceive all the sounds within a wide
frequency band ranging from the rustling of a leaf to the roar of a
jet plane. However, if the sound level in your brain were to be
measured by a sensitive device at that moment, it would be seen
that complete silence prevails there.
Our perception of odour forms in a similar way. Volatile
molecules emitted by things such vanilla or a rose reach the re-
ceptors in the delicate hairs in the epithelium region of the nose
and become involved in an interaction. This interaction is trans-
mitted to the brain as electrical signals and perceived as smell.
Everything that we smell, be it nice or bad, is nothing but the
brain's perceiving of the interactions of volatile molecules after
they have been transformed into electrical signals. You perceive
the scent of a perfume, a flower, a food that you like, the sea, or
other odours you like or dislike in your brain. The molecules
themselves never reach the brain. Just as with sound and vision,
what reaches your brain is simply electrical signals. In other
words, all the odours that you have assumed to belong to exter-
nal objects since you were born are just electrical signals that you
feel through your sense organs. You can never have direct expe-
rience of the true nature of a scent in the outside world.
