But the reason is obvious. Civilized society has placed the human race in artificial circumstances. Instead of listening to the dictates of reason, making ourselves acquainted with the nature of the human constitution, and studying to preserve it in health and vigor, we yield to the government of ignorance and presumption. The first moment, even, in which we draw breath, sees us placed under the control of individuals who are totally inadequate to the important charge of preserving the infant constitution in its original state, and aiding its progress to maturity. And thus it is that though infants, as a general rule, may be said to be born healthy, few actually remain so. Seldom, indeed, do we find a person who has arrived at maturity wholly free from disease, even in those parts of our country which are reckoned to have the most healthy climate. It is indeed commonly said, that a large proportion, both of children and adults, among the agricultural portion of our population, are healthy. But it is not so. There is room for doubt whether, on the whole, the farmers of this country are healthier than the mechanics, or much more so than the manufacturers; or the whole mass of the country population healthier than that of the crowded city. The causes of disease are sufficiently numerous, in all places and conditions; and this will continue to be the fact, not merely until parents and teachers shall become more enlightened, but until many generations have been trained under their enlightened influence. If the children and adults among our agricultural population derive from their employments in the open air a more ruddy appearance than those either of the city or country who are confined more to their rooms; or to a vitiated atmosphere, and to numerous other sources of disease, and if they _appear_ more favored with health, I have learned, by accurate observation, that these appearances are somewhat deceptive. Their active sports and employments in the open air give them a stronger appetite than any other class of people; and the indulgence of this appetite, not only with articles which are heating or indigestible in their nature, but with an unreasonable quantity even of those which are considered highly proper, is almost in an exact proportion. And it is hence scarcely possible for the causes of disease and premature death to be more operative in factories and in cities than in farm houses and the country. Indeed it may be questioned whether the abuses of the ANIMAL part of man--more common in some of their forms in country than in city--though they may be less conspicuous, are not more certainly and even more immediately destructive than those abuses which, in city life, and bustle, and competition, affect more the MORAL nature.
