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.
