It does not fall within the scope of my present purpose to dwell upon the familiar aspect of the effects of alcohol suggested by the last sentence. It requires no scientific experiments to prove that one of the subtlest effects of this many-sided drug is to produce a craving for itself, while weakening the will that could resist that craving. But beyond noting that this is precisely in line with what we have everywhere seen to be the typical effect of alcohol--the weakening of higher functions and faculties, with corresponding exaggeration of lower ones--I shall not comment here upon this all too familiar phase of the alcohol problem. Throughout this paper I have had in mind the hidden cumulative effects of relatively small quantities of alcohol rather than the patent effects of excessive indulgence, I have had in mind the voluntary "social" drinker, rather than the drunkard. I have wished to raise a question in the mind of each and every habitual user of alcohol in "moderation" who chances to read this article, as to whether he is acting wisely in using alcohol habitually in any quantity whatever. If in reply the reader shall say: "There is some quantity of alcohol that constitutes actual moderation; some quantity that will give me pleasure and yet not menace me with these evils," I answer thus: Conceivably that is true, though it is not proved. But in any event, no man can tell you what the safe quantity is--if safe quantity there be--in any individual case. We have seen how widely individuals differ in susceptibility. In the laboratory some animals are killed by doses that seem harmless to their companions. These are matters of temperament that as yet elude explanation. But this much I can predict with confidence: whatever the "safe" quantity of alcohol for you to take, you will unquestionably at times exceed it. In a tolerably wide experience of men of many nations, I have never known an habitual drinker who did not sometimes take more alcohol than even the most liberal scientific estimate could claim as harmless. Therefore I believe that you must do the same. So I am bound to believe, on the evidence, that if you take alcohol habitually, in any quantity whatever, it is to some extent a menace to you. I am bound to believe, in the light of what science has revealed: (1) that you are tangibly threatening the physical structures of your stomach, your liver, your kidneys, your heart, your blood-vessels, your nerves, your brain; (2) that you are unequivocally decreasing your capacity for work in any field, be it physical, intellectual, or artistic; (3) that you are in some measure lowering the grade of your mind, dulling your higher esthetic sense, and taking the finer edge off your morals; (4) that you are distinctly lessening your chances of maintaining health and attaining longevity; and (5) that you may be entailing upon your descendants yet unborn a bond of incalculable misery.
