If the preacher were to say that anything is a sin which uses up the strength we need for daily duties, and leaves us fagged out and irritable at just those times and in just those places when and where we need most to be healthy, cheerful, and self-possessed, he would say a thing that none of his hearers would dispute. If he should add, that dancing-parties, beginning at ten o’clock at night and ending at four o’clock in the morning, do use up the strength, weaken the nerves, and leave a person wholly unfit for any home duty, he would also be saying what very few people would deny; and then his case would be made out. If he should say that it is wrong to breathe bad air and fill the stomach with unwholesome dainties, so as to make one restless, ill-natured, and irritable for days, he would also say what few would deny, and his preaching might have some hope of success. The true manner of judging of the worth of amusements is to try them by their effects on the nerves and spirits the day after. True amusement ought to be, as the word indicates, _recreation_,--something that refreshes, turns us out anew, rests the mind and body by change, and gives cheerfulness and alacrity to our return to duty. The true objection to all stimulants, alcoholic and narcotic, consists simply in this,--that they are a form of overdraft on the nervous energy, which helps us to use up in one hour the strength of whole days. A man uses up all the fair, legal interest of nervous power by too much business, too much care, or too much amusement. He has now a demand to meet. He has a complicate account to make up, an essay or a sermon to write, and he primes himself by a cup of coffee, a cigar, a glass of spirits. This is exactly the procedure of a man who, having used the interest of his money, begins to dip into the principal. The strength a man gets in this way is just so much taken out of his life-blood; it is borrowing of a merciless creditor, who will exact, in time, the pound of flesh nearest his heart. Much of the irritability which spoils home happiness is the letting-down from the over-excitement of stimulus. Some will drink coffee, when they own every day that it makes them nervous; some will drug themselves with tobacco, and some with alcohol, and, for a few hours of extra brightness, give themselves and their friends many hours when amiability or agreeableness is quite out of the question. There are people calling themselves Christians who live in miserable thraldom, forever in debt to Nature, forever overdrawing on their just resources, and using up their patrimony, because they have not the moral courage to break away from a miserable appetite.
