Now it is possible for most people, indeed for all who have not some organic morbid condition, to control this spread of pain beyond its original connections, provided only they will to do so, refuse to be ruled by their dreads and proceed to divert attention from the painful condition to other subjects. Here is why the man who bravely faces pain actually lessens the amount that he has to bear. There is no pain in the part affected. That we know, because any interruption of the nerve tract leading from the affected part to the brain {126} eliminates the pain. In the same way, the obtunding of the nerve cells in the cortex by anaesthetics or of the conducting nerve apparatus on the way to the brain by local anaesthesia, will have a like effect. Anything then that will interfere with the further conduction of the pain sensation and the cortical cells directly affected will lessen the sense of pain, and this is what happens when a man settles himself firmly to the thought that he will not allow himself to be affected beyond what is the actual reaction of the nerve tissues to the part. As a matter of fact, the anticipation of pain due to the dread of it predisposes the part to be much more sensitive than it was before. We can all of us readily make experiments which show this very clearly. Ordinarily we have a stream of sensations flowing up from the surface of the body to the brain, consequent upon the fact that the skin surface is touched by garments over most of the body, and that our nerves of touch respond to their usually rather rough surface. We have learned to pay no attention to these because we have grown accustomed to them, though any one who thinks that they are negligible should witness the writhings of a poor Indian under the stress {127} of being civilized when he is required to wear a starched shirt for the first time. Ordinarily Indians have learned to suppress their feelings, but the shirt with its myriad points of contact, all of them starchily scraping, usually proves too much for his equanimity, and he wiggles and twists to such an extent as shows very clearly that he is extremely uncomfortable. Most people have something of the same feeling the first day that they change into woolen underclothes after they have been wearing cotton for months, and the sensation is by no means easy to bear with equanimity.
