One bit of Mr. Parton's philosophy still calls for brief comment. He wishes to speak of the general tendency of the poor man's pipe; and he means to say "that it tends to make him satisfied with a lot which it is his chief and immediate duty to alleviate,--he ought to hate and loathe his tenement-house home." A fine specimen of the dyspeptic philosophy of radicalism! Despise all you have got, because you cannot have something better. We believe it is sometimes described as the philosophy of progress. There can of course be no doubt that Mr. Parton's hod-carrier will work all the better next day, if he only spends the night in fretting and getting peevish over his "tenement-house home." Such then, in sum and substance, is our reformer's indictment against tobacco. It lowers the tone of our systems, and it makes us contented; it wastes money, it allies us with barbarians, and it transforms us--_mira quadam metamorphosi_--into swine. Goethe, therefore, did not smoke, the Coming Man will not smoke, and General Grant, with tardy repentance, "has reduced his daily allowance of cigars." And as for Mr. Buckle, the author of an able book which Mr. Parton rather too enthusiastically calls "the most valuable work of this century,"--if Mr. Buckle had but lived, he would doubtless have inserted a chapter in his "History," in which tobacco would have been ranked with theology, as one of the obstacles to civilization. Throughout Mr. Parton's rhapsody, the main question, the question chiefly interesting to every one who smokes or wishes to smoke, is uniformly slurred over. Upon the question whether it is unhealthy to smoke, the Encyclopædias which Mr. Parton has consulted do not appear to have helped him to an answer. Yet this is a point which, in making up our minds about the profitableness of smoking, must not be taken for granted, but scientifically tested. What, then, does physiology say about this notion--rather widespread in countries over which Puritanism has passed--that the use of tobacco is necessarily or usually injurious to health? Simply that it is a popular delusion--a delusion which even a moderate acquaintance with the first principles of modern physiology cannot fail to dissipate. Nay, more; if our interpretation shall prove to be correct, it goes still further. It says that smoking, so far from being detrimental to health, is, in the great majority of cases, where excess is avoided, beneficial to health; in short, that the careful and temperate smoker is, other things equal, likely to be more vigorous, more cheerful, and more capable of prolonged effort than the man who never smokes.
