“ The greatest workers and thinkers of modern times have been inveterate smokers. At the same time, it is idle to deny that smoking to excess weakens the eyesight, impairs the digestion, plays havoc with the nerves, and interferes with the action of the heart. I have been a constant smoker for nearly forty years; but had I my life to live over again I would never touch tobacco in any shape or form. It is to the man who sits all day long at a desk, poring over books and scribbling 'copy,' that smoking is deleterious. ”

“ There is no mistake so fatal to the proper development of man and woman, as to pile on the immature brain, and on the yet unfinished fabric of the human body, a weight of premature and, therefore, unnatural study. In most of those cases where Nature has intended to produce a first-class intellect, she has guarded her embryo genius by a stubborn slowness of development. Moderate study and plenty of play and exercise in early youth are the true requisites for a noble growth of intellectual powers in man, and for its continuance to old age. ”

“ Another cause to which I attribute my extraordinary degree of health, has been not merely continued country exercise in walking and gardening, but, now and then, making a clean breach and change of my location and mode of life. Travel is one of the great invigorators of the system, both physically and intellectually. When I have found a morbid condition stealing over me, I have at once started off on a pedestrian or other journey. The change of place, scene, atmosphere, of all the objects occupying the daily attention, has at once put to flight the enemy. ”

“ From one to two and a half small wine glasses of claret or burgundy is the limit of what I can take—and that only at dinner—without conscious harm. One glass of sherry or port I find every way injurious. Whisky and brandy are to me simply poisons, destroying my power of enjoyment and of thought. Ale I can only drink when very much in the open air. As to tobacco, I have never smoked much, but I can either not smoke, as at present, or go to the limit of two small cigarettes in twenty-four hours. Any good effects of tobacco become with me uncertain in proportion to the frequency of smoking. ”

“ MARK TWAIN. I have not had a large experience in the matter of alcoholic drinks. I find that about two glasses of champagne are an admirable stimulant to the tongue, and is, perhaps, the happiest inspiration for an after dinner speech which can be found; but, as far as my experience goes, wine is a clog to the pen, not an inspiration. I have never seen the time when I could write to my satisfaction after drinking even one glass of wine. As regards smoking, my testimony is of the opposite character. ”

“ I drink myself, but not during the hours of work; and I smoke-pretty habitually. My own experience and belief is, that both alcohol and tobacco, like most blessings, can be turned into curses by habitual self-indulgence. Physiologically speaking, I believe them both to be invaluable to humankind. The cases of dire disease generated by total abstinence from liquor are even more terrible than those caused by excess. With regard to tobacco, I have a notion that it is only dangerous where the vital organism, and particularly the nervous system, is badly nourished. ”

“ From boyhood up to the present time—I am now 44—I have never been in the habit of drinking or of smoking, nor did it ever occur to me that such habits were essential to health or helpful to brain work. It is my firm conviction that neither the head nor the hand derives any fresh power from the use of stimulants. It is only habits already contracted which give to alcohol and tobacco their so-called stimulating properties, and engender a strong craving for them, which those who are not enslaved by such habits never experience. ”

“ It is natural as time goes on that new wants should be acquired, and new luxuries discovered, and doubtless it is in the abuse, and not in the use, of such things that the danger lies; but we all know how prone humanity is to abuse in its indulgences. It is, I believe, an admitted fact that even people who are considered to be strictly temperate as a rule, habitually take more wine than is good for them. With regard to tobacco, I cannot help thinking that its introduction by civilised races has been an unmixed evil. ”

“ What is the real influence of stimulants and narcotics upon the brain? Do they give increased strength, greater lucidity of mind and more continuous power? Do they weaken and cloud the intellect, and lessen that capacity for enduring a prolonged strain of mental exertion which is one of the first requisites of the intellectual life? Would a man who is about to enter upon the consideration of problems, the correct solution of which will demand all the strength and agility of his mind, be helped or hindered by their use? ”

“ What kind of slumber could a man, leading such a life as this, be expected to enjoy? On the whole, it would appear that M. Jules Noriac's habits were diametrically opposed to the preservation of health and the prolongation of life, and that he died quite as much from too much Boulevard and too much night work, as from too much smoking. There are vast numbers of French journalists and men of letters who, without being necessarily "Bohemians," consume their health and shorten their lives by this continuous and feverish race against time. ”

“ And the older men, who find it so difficult to find leisure, and who when they find it cannot enjoy it because they have a number of slight ailments which do not allow them perfect health, or which keep them in over-excitement or over-depression, let them try—though it will need a struggle—whether the total abandonment of alcohol will not lessen all their ailments, and by restoring a better temper to the body—for the body with alcohol in it is like a house with an irritable man in it—enable them not only to work better, but to enjoy their leisure. ”

“ I will only add that I have never found the slightest difficulty, physical or moral, in an instantaneous change of habit to complete abstinence. Instead of feeling any depressing want of what I had relinquished, I have found a direct refreshment and satisfaction in the simpler modes of life. Few things, I believe, do more, at a minimum of cost, to lighten the spirits and sweeten the temper of families and of society, than the repudiation of artificial indulgences. ”

“ I do not know whether those who use alcohol as a stimulant have experienced the same. No doubt they have succeeded in exciting their nervous sensibilities; but I assert that the real work of creative genius is accomplished in the intervals of this purturbation of the nerves which by some is deemed so essential to intellectual labour. When the nerves are excited to the highest pitch, they occasionally suffer, the transitory cessation from which is the divine moment of human creation. ”

“ I am not of his lordship's opinion; but seeing the great longevity of many of our most eminent lawyers, and some of whom in early life seemed disposed to live fast rather than long, I am more than ever confirmed in my opinion of the vitalizing influences of temperance, good air, and daily activity, which, with the benefits of change and travel, can so far in after life save those whom no original force of constitution could have saved from the effects of jollity, or of gigantic efforts of study in early life. ”

“ I have an artist friend whose brain is livelier after a bottle of Carlowitz, which would stifle my mind, and to him my strong cup of tea would be poison. We are both, I think, of nervous organization, but how differentiated I cannot tell. My pulse goes always rather too quickly; a little emotional disturbance sets it going at an absurdly rapid rate for hours, and extreme physical fatigue follows. My conviction is that no one rule applies to all men, but for men like me alcohol is certainly not necessary, and at best of little use. ”

“ But if mental labour be continued for a long time, until exhaustion be felt, then the resort to a pipe gives to some habitues a feeling of relief; it soothes, it is said, and gives new impetus to thought. This is the practical experience of almost all smokers, but few men become so habituated to the pipe as to commence well a day of physical or mental work on tobacco. Many try, but it almost invariably obtains that they go through their labours with much less alacrity than other men who are not so addicted. ”

“ I smoke when hard at work—chiefly cigarettes. After a long sitting (as I do not smoke while working from nature) , a cigarette is a soother for which I get a perfect craving. In the evening, or when I am in the country doing nothing, I scarcely smoke at all, and do not feel the want of it there; nor do I then take at evening dinner more than one or two glasses of wine, and I have observed that the same quantity which would make me feel giddy in the country when in full health and vigour, would not have the slightest effect on me when taken after a hard day's work. ”

“ Those attacks of depression which come to every man at times who lives too sedentary a life rarely visit me now, and when depression does come from any trouble, I can overcome it far more quickly than before. The fact is, alcohol, even in the small quantities I took it, while it did not seem to injure health, injures the fineness of that physical balance which means a state of health in which all the world is pleasant. ”

“ As you see, I consider that tobacco and alcohol do not act as stimulants, but rather as narcotics. With me they induce after the first moment of excitement a sort of calm and somnolence altogether incompatible with severe work; and I prefer coffee, always on the condition that as soon as the effort to be accomplished is finished the use of it must cease. I will not invoke the precedents of the celebrated men who have been led to make great use of coffee without impairing their health. ”

“ Therefore, I appeal to the young and the old, to try abstinence for the very reasons they now use alcohol—in order to increase their power of work and their enjoyment of life. Let the young make the experiment of working on water only. Alcohol slowly corrupts and certainly retards the activity of the brain of the greater number of men. They will be able to do all they have to do more swiftly. ”

“ The only sure brain stimulants with me are plenty of fresh air and tea; but each of these in large quantity produces a kind of intoxication: the intoxication of a great amount of air causing wakefulness, with a delightful confusion of spirits, without the capacity of steady thought; tea intoxication unsettles and enfeebles my will; but then a great dose of tea often does get good work out of me (though I may pay for it afterwards) , while alcohol renders all mental work impossible. I have been accustomed to make the effects of tea and wine a mode of separating two types of constitution. ”

“ As a matter of nature, I do not believe that a man works either better or worse for the use of tobacco, unless he smokes so much as to injure his general health. Alcoholic drinks are, of course, mentally as well as physically stimulative, and I have found them useful at a pinch. But everybody knows that stimulants are reactionary, and it is pretty certain that in the end they take more out of a man than they put into him. ”

“ Neither do I make use of coffee, which equally excites the nervous system, although, like all the world, I have observed that this substance gives a certain intellectual activity. What I have found out most clearly is what everyone has observed from time immemorial—that the clearest ideas, the happiest and most fruitful expressions, come in the morning, after the repose of the night, and after sleep—when one has it, but of which I have not a very large share. ”

“ I very much doubt the quickening or brightening of the wits which bacchanalian poets have conventionally attributed to alcohol. An abstainer in a party of even moderate topers finds their jokes dull and their anecdotes pointless, and his principal amusement consists in his observation of their curious bluntness to the groundlessness of their merriment. There is no more fatal habit to a literary man than that of using alcohol as a stimulant between meals. ”

“ I certainly never drank a glass of wine or any other liquor in view of mental stimulus, and did not know it was ever seriously regarded as having any such effect, except in so far as it might invigorate the body, which I now find it does not do; but in case of sedentary occupations is positively injurious in its effects. Until mankind can rise above beer and tobacco, the race will remain degraded, as it now is, mentally, socially and physically. ”

“ I cannot call to mind a single case, except that of Goethe, where great mental labour has been carried on without external support of some sort; which seems to imply an instinctive knowledge of how to get more out of the brain machine than is possible under normal conditions. Of course the means must differ more or less in each individual case; and sometimes the owner of a creative brain must decide whether he will let it lie fallow for health's sake, or whether for work's sake he will let life and health go. ”

“ When we read that literary producers of any power have gone on working up to the last, even in the near approach of death, we usually find the work done has been of a not unwelcome kind, and often that it has formed part of a long-cherished design. But when the disease of which the sufferer is dying is consumption, or some disease which between paroxysms of pain leaves spaces of ease and rest, it is nothing wonderful that work should be done. ”

“ The savage, with the mansions of his soul unfurnished, buries his restless energy under its shadow. The civilised man, overburdened with mental labour, or with engrossing care, seeks the same shade; but it is shade, after all, in which in exact proportion as he seeks it, the seeker retires from perfect natural life. ”

“ The editor of a newspaper will tell you that, if he has been dining out, he cannot with confidence write a leading article until he has allowed sufficient time to elapse from the effect of the wine he has drunk, in moderation, to pass away; and even the novelist, whose brain-work is in the regions of imagination, will relate a similar experience.... In a person accustomed to the use of tobacco the intellectual work is difficult when smoking cannot be indulged in, the mind cannot easily be concentrated on a subject, and unrest is produced—but this disappears when recourse is had to smoking ”

“ The question you ask concerning the effects of alcohol and tobacco upon the health of brain-workers, relatively (I presume) to myself, is a complex one. Personally, I find with often excessive work in the way of lecturing, long railway journeys, and late hours, writing at other times, that I digest my food with greater ease when I take a little claret or beer with meals. Experiment has convinced me that the slight amount of alcohol I imbibe in my claret is a grateful stimulus to digestion. As to smoking, I take an occasional cigar, but only after dinner, and never during the day. ”

“ PROFESSOR EVERETT. In reply to your letter, I have to say that I think all stimulants, whether in the form of alcoholic drinks, tea or coffee, or tobacco, should be very moderately used. For my own part, I have never smoked or snuffed, and my daily allowance of alcoholic drinks is a so-called pint bottle of beer or two glasses of wine. I have more frequently suffered from nervous excitability due to tea or coffee, than from any other kind of stimulant. I can compose best when my brain is coolest and my digestion easiest. I do not believe in artificial stimulus to literary effort. ”

“ I am a firm believer in the value of a moderate use of tobacco and alcohol for the brain worker. I generally smoke one pipe in the morning, before work, and one at night, after work (or the equivalents of a pipe) . I seldom smoke while I work, and do not find it helpful. I drink two glasses of sherry (or their equivalents) , as a rule daily, and take them at late dinner—not at lunch. If troubled with sleeplessness, I find a glass of sherry, and a few biscuits, followed by smoking, a tolerably safe cure, but not always to be relied upon. ”
