"I would that every individual whom I have the honor to address would assist in the education of the blind, so far as to give them just and Christian views of this subject. I would that all should work for society; not for society to-day alone, but for the society of future ages; not in any one narrow, partial way, but upon a broad scale, and in every way in which they can be useful. If a person congenitally blind, or strongly predisposed to become so, or one who marries a person so born or so disposed, has blind offspring in consequence of it, I ask, is he not as responsible, in a moral point of view, for the infirmity of his children as though he had put out their eyes with his own hands?
"You may suppose, perhaps, that the infirmity of blindness would incapacitate sufferers from winning the affections of seeing persons; and that, with respect to two blind persons, the sense of incapacity to support a family would prevent them from uniting themselves. In the first place, I answer, that seeing people do no better than the blind. Even a blind man may perceive that many marriages are mere matters of course, resulting from juxtaposition of parties; and rarely matters where the purer affections and higher moral sentiments are consulted. And, in the second place, that incapacity of supporting a family will not weigh a feather in the balance with desire, unless the intellectual and moral nature is enlightened and cultivated. Do we not see, every day, cases of misery entailed upon whole families, because one of the parties had overlooked or disregarded moral infirmity, which ought to have been a greater objection than any physical defect—than even blindness or deafness?
"But no process of reasoning is required, for there stand the facts. The blind not only seek for partners in life, but are sometimes sought by seeing persons; and numerous instances have occurred within my knowledge. It is true, that despair of success in any other quarter, or an equally unworthy motive, may induce some to seek for partners among the blind, or the blind to unite with the blind; but still, there is the evil.
"My observation induces me to think that the blind, far more than seeing persons, are fond of social relations, and desirous of family endearments. A moment's thought would induce one to conclude that this would naturally be the case; a moment's observation convinces one that it is so. Now I have found among them some of the most pious, intelligent, and disinterested beings I ever knew; but hardly more than one who was prepared to forego the enjoyments of domestic relations. And how can we expect them to be so, more than seeing people? The fact is, but very few persons in the community give any attention to the laws of their organic nature, and the tendency to hereditary transmission of infirmities. Very few consider that they owe more to society than to their individual selves; that if we are to love our neighbor as ourself, we must, of course, love all our neighbors, collectively, more than the single unit which each one calls I.
"I would that considerations of this kind had more weight with the community generally. I would that the subject were more attended to, and that the violation of the laws of our organic nature were less frequent in our country. There is one great and crying evil in our system of education; it is, that but part of man's nature is educated, and that our colleges and schools doom young men for years to an uninterrupted and severe exercise of the intellectual faculties, to the comparative neglect of their moral, and still more of their physical nature. Nay, not only do they neglect their physical nature—they abuse it; they sin against themselves and against God; and though they sin in ignorance, they do not escape the penalties of His violated laws. Hence you see them pale, and wan, and feeble; hence you find them acknowledging, when too late, the effects of severe application. But do they acknowledge it humbly and repentingly, as with a consciousness of sin? No, they often do it with a secret exultation, with a lurking feeling that you will say or think, 'Poor fellow, his mind is too much for his body!' Nonsense! his mind is too weak; his knowledge too limited; he is an imperfect man; he knows not his own nature. But if he has no conscientiousness, no scruple about impairing his own health and sowing the seeds of disease, he has less about entailing them upon others. And a consumptive young man or woman—the son or daughter of consumptive parents—hesitates not to spread the evil in society, and entail puny faces, weakness, pain, and early death upon several individuals, and punish their children for their own sins.
"Is this picture too high-colored? Alas! no. And if I showed you satisfactorily that sin against the organic laws caused so great a proportion of blindness, how much more readily will you grant that the same sin gives to so many of our population the narrow chest, the hectic flush, the hollow cough, which makes the victim doomed, by his parent, to consumption and early death! Do you not see, every Sabbath, at church, the young man or woman, upon whose fair and delicate structure the peculiar impress of the early doomed is stamped? and as a slight but hollow cough comes upon your ear, does it not recall the death-knell which rang in the same sad note before to the father or mother? Who of you has not followed some young friend to his long resting-place, and found that the grass had not grown rank upon the grave of his brother? that the row of white marbles, beneath which slept his parents and sisters, were yet glistering in freshness, and that the letters which told their names and their early death seemed clear as if cut but yesterday?
"They tell us that physical education is attended to in this country; and yet, where is the teacher, where is the clergyman even, who dares to step forth in these cases, and say to those who are doomed, you must not and shall not marry? and where are the young men and women who would listen to them if they did? It is not that they are wanting in conscientiousness; they may be conscientious and disinterested; but they do not know that they are doing wrong, because they are not acquainted with the organic laws of their nature. All that is done in schools or colleges toward physical education is the mere strengthening of the muscular system by muscular exercise; but this is not half enough. These remarks may be deemed irrelevant to my subject, but they can not be lost to an audience whose highest interest is the education of man; and if I am mistaken in supposing that little attention has been paid to the subject, its importance will guaranty its repetition."
Before dismissing this subject, I will introduce two additional quotations from American authors, whose opinions are received by the medical profession in this country not only, but throughout Europe. In both instances, I copy from works published in Great Britain, into which the opinions of these American writers have been quoted. In regard to hereditary transmission, Dr. Caldwell observes: "Every constitutional quality, whether good or bad, may descend, by inheritance, from parent to child. And a long-continued habit of drunkenness becomes as essentially constitutional as a predisposition to gout or pulmonary consumption. This increases, in a manifold degree, the responsibility of parents in relation to temperance. By habits of intemperance, they not only degrade and ruin themselves, but transmit the elements of like degradation and ruin to their posterity. This is no visionary conjecture, the fruit of a favorite and long-cherished theory. It is a settled belief resulting from observation—an inference derived from innumerable facts. In hundreds and thousands of instances, parents, having had children born to them while their habits were temperate, have become afterward intemperate, and had other children subsequently born. In such cases, it is a matter of notoriety that the younger children have become addicted to the practice of intoxication much more frequently than the older, in the proportion of five to one. Let me not be told that this is owing to the younger children being neglected, and having corrupt and seducing examples constantly before them. The same neglects and profligate examples have been extended to all, yet all have not been equally injured by them. The children of the earlier births have escaped, while those of the subsequent ones have suffered. The reason is plain. The latter children had a deeper animal taint than the former."—Transylvania Journal.
Physiologists in general coincide in the belief that a vigorous and healthy physical and mental constitution in the parents communicates existence in the most perfect state to their offspring, while impaired constitutions, from whatever cause, are transmitted to posterity. In this sense, all who are competent to judge are agreed that the Giver of life is a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate him or violate his laws. Strictly speaking, it is not disease which is transmitted, but organs of such imperfect structure that they are unable to perform their functions properly, and so weak as to be easily put into a morbid state or abnormal condition by causes which unimpaired organs are able to resist.
My last quotation on this point is from a lecture delivered by Dr. Warren before the American Institute of Instruction, copied into the "Schoolmaster," a work published in London under the superintendence of the Society for the Diffusion of Useful Knowledge:
