In attempting to describe the influence of alcohol upon the brain and nervous system, it will be well for us to keep steadily in mind the fundamental difference between stimulant and narcotic doses, which was described at some length in our chapter on Tobacco. It is hardly necessary to state that Mr. Parton neither recognizes, nor appears dimly to suspect, the existence of any such distinction. His is one of those minds in which there are no half-way stations. With him, to rise above zero is inevitably to fly to the boiling-water point. But without keeping in mind this all-important distinction, any inquiry into the physiological effects of alcohol must end in confusion and paradox. Remembering this, let us examine first the narcotic, and then the stimulant effects of alcohol upon the nervous system. The narcotic effects of alcohol upon the entire human organism are so bad that even the teetotaler does not need to exaggerate them. The stomach is not only damaged, and the cerebrum ruined, but a slow molecular change takes place throughout the nervous system, which ends by destroying the power of self-control and utterly demoralizing the character. Far be it from us, therefore, to palliate the consequences which sooner or later are sure to follow the wretched habit of drinking narcotic quantities of alcohol; or to look without genuine sympathy upon the philanthropic, though usually misguided attempts which radical aquarians are continually making to diminish the evil. Their feelings are often as right as their science is wrong. But because we believe that for a book to be of any value whatever, it must be _true_, and that false science can never, in the long run, be of practical benefit, we are not therefore to be set down as lukewarm in our abhorrence of alcoholic intemperance. Those who keep their hearts in subjection to their heads are often supposed to have no hearts at all. Those who do not forthwith get angry and utter "spurts of extravagance" whenever any social evil is mentioned, are often thought to be in secret sympathy with it. But how could we, by writing reams of fervid declamation, more forcibly express our disapproval of drunkenness than by recording the cold scientific statement that the first narcotic symptom produced by alcohol is a symptom of incipient paralysis?
