246 THE EVOLUTION DECEIT
However, if the sound level in your
brain were to be measured by a sensi-
tive device at that moment, it would be
seen that complete silence prevails
there.
Our perception of odour forms in
a similar way. Volatile molecules emit-

This interaction is transmitted to the other smells we like or dislike in our
brains.
brain as electrical signals and per-
ceived as smell. Everything that we
smell, be it nice or bad, is nothing but the brain's perceiving of the interac-
tions 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 reach-
es your brain is simply electrical signals. In other words, all the odours that
you have assumed to belong to external objects since you were born are just
electrical signals that you feel through your sense organs. You can never
have direct experience of the true nature of a scent in the outside world.
Similarly, there are four different types of chemical receptors in the
front part of a human being's tongue. These register salty, sweet, sour, and
bitter tastes. Our taste receptors transform these perceptions into electrical
signals after a chain of chemical processes and transmit them to the brain.
These signals are perceived as taste by the brain. The taste you get when you
eat a chocolate bar or a fruit that you like is the interpretation of electrical
signals by the brain. You can never reach the object on the outside; you can
never see, smell or taste the chocolate itself. For instance, if taste nerves that
travel to your brain are cut, nothing you eat at that moment will impinge
upon your brain; you will completely lose your sense of taste.
And here is another interesting fact: We can never be sure that what we
feel when we taste a food and what another person feels when he tastes the
same food, or what we perceive when we hear a voice and what another
person perceives when he hears the same voice are the same. On this point,
