But, you see, all these senses are but modifications of the original sense of feeling or touch.  The eye records the touch or feeling of the light-waves which strike upon it.  The ear records the touch or feeling of the sound-waves or vibrations of the air, which reach it.  The tongue and other seats of taste record the chemical touch of the particles of food, or other substances, coming in contact with the taste-buds.  The nose records the chemical touch of the gases or fine particles of material which touch its mucous membrane.  The sensory-nerves record the presence of outer objects coming in contact with the nerve ends in various parts of the skin of the body.  You see that all of these senses merely record the contact or “touch” of outside objects.

But the sense organs, themselves, do not do the knowing of the presence of the objects.  They are but pieces of delicate apparatus serving to record or to receive primary impressions from outside.  Wonderful as they are, they have their counterparts in the works of man, as for instance:  the camera, or artificial eye; the phonograph, or, artificial ear; the delicate chemical apparatus, or artificial taster and smeller; the telegraph, or artificial nerves.  Not only this, but there are always to be found nerve telegraph wires conveying the messages of the eye, the ear, the nose, the tongue, to the brain—­telling the something in the brain of what has been felt at the other end of the line.  Sever the nerves leading to the eye, and though the eye will continue to register perfectly, still no message will reach the brain.  And render the brain unconscious, and no message will reach it from the nerves connecting with eye, ear, nose, tongue, or surface of the body.  There is much more to the receiving of sense messages than you would think at first, you see.

Now all this means that the ego, or soul, or mind, if you prefer the term—­is the real Knower who becomes aware of the outside world by means of the messages of the senses.  Cut off from these messages the mind would be almost a blank, so far as outside objects are concerned.  Every one of the senses so cut off would mean a diminishing or cutting-off of a part of the world of the ego.  And, likewise, each new sense added to the list tends to widen and increase the world of the ego.  We do not realize this, as a rule.  Instead, we are in the habit of thinking that the world consists of just so many things and facts, and that we know every possible one of them.  This is the reasoning of a child.  Think how very much smaller than the world of the average person is the world of the person born blind, or the person born deaf!  Likewise, think how very much greater and wider, and more wonderful this world of ours would seem were each of us to find ourselves suddenly endowed with a new sense!  How much more we would perceive.  How much more we would feel.  How much more we would know.  How much more we would have to talk about.  Why, we are really in
