I once heard of a man who on his death-bed made a singular will. He had no houses or lands to bequeath his children, but he had observed that they had inherited much from him, and so he made a formal bequest to them of that which they already possessed.
He wrote: "I bequeath to my son John my big bony frame and the slouching gait I acquired by carelessness, also my inherited tendency to consumption. To my daughter Mary I bequeath my sallow complexion and torpid liver, which are the result of my gross living; also my melancholy disposition and tendency to look on the dark side of life. To my son Samuel I give my love for alcoholic liquors and my irritable disposition; to my daughter Jane my coarseness of thought and my unwillingness to be restrained in my desires, and also my tendency to commit suicide."
"A very strange will," said everybody, and yet it was a will that was probated long before the testator's death. That it gave perfect satisfaction I will not assert, but it was never contested and paid no fees to lawyers.
Just such wills are being made daily by thelives and conduct of young people, though they are not put into writing. Some time in the future, however, they will be written into "living epistles, known and read of all men."
Other wills are being made daily that through sober, virtuous, youthful lives will bequeath to posterity dowers of health, strength, purity and power.
This being true, it seems only a part of prudent foresight to study in youth the law that governs the transmission of personal characteristics to the future "denizens of life's great city." This law is known as Heredity, and its first written record is in the first chapter of Genesis, where it is written that "Every plant and animal shall bring forth after its kind." We are so accustomed to seeing the results of this law that we give it little or no thought. We see that grass springs up each year on our lawns and meadows. We know that if we put the seeds of a certain flower in the ground, that kind of flower will always spring up, never another kind. The farmer is not anxious, after he sows wheat, for fear that the crop will be rye or barley. We expect that the young of cats will be kittens, of geese will be goslings, of men will be human children, and we are never disappointed. The law holds good under all circumstances.
We see, too, that there are certain race characteristics that maintain. The Mongolian racehas peculiar high cheek-bones, sallow complexions and eyes set in bias, and we recognize the Japanese or Chinese at once, even though dressed in the garb of our country. So, too, we recognize the African or the Caucasian by certain marked characteristics. This transmission of racial traits we call race heredity.
Then each race has its own traits, physical or mental, which we recognize as national, and so speak of them. We always mention thrift as an attribute of the Teutonic nations; the Irishman we characterize as witty and pugnacious; the Frenchman as polite; the American as progressive.
Each individual has not only his human inheritance, his race inheritance and his national characteristics, but he has also an endowment of family traits.
But we are not made up of odds and ends of ancestral belongings alone. We have in ourselves something that is original, that makes us different from each other, and from all others. I have sometimes thought that we are somewhat like patchwork quilts, the parti-colored blocks being set together by some solid-colored material; or, better still, we are like "hit and miss" rag carpets, with a warp of our own individuality, filled in with a woof made of qualities and capacities of all those who have preceded us. You know, in making "hit and miss" rag carpets we take little strips and bitsof various materials and all colors, and sew them together without regard to order or arrangement, and these long strips are woven back and forth in the warp until the carpet is woven, showing no set pattern, but a mingling of tints and shades that is sometimes crude and unsightly, sometimes soft and artistic.
I used, in childhood, to find great delight in seeking among the blended colors in the carpet for scraps of clothing which I recognized as having belonged to father or mother, or perhaps even to grandparents. Even now, in my maturer years, I am interested in finding in myself the physical, mental or moral characteristics of those same ancestors; and you, no doubt, can do the same, while some of your traits seem to be yours entirely, constituting individual variations upon ancestral inheritances.
Nature has been doing for centuries, unheeded, what the photographer of to-day thinks is a modern discovery, that is, making composite photographs of us all.
Through this law of inheritance have arisen the intellectual, the moral or the criminal types of humanity, and the process is continuing; the types are becoming more and more marked, or modifying influences are being brought in to change the type.
These influences are also the result of law, even though we may not be able to trace themto their cause. Knowing this, however, we begin to see that heredity is not fatality; that the power to modify the endowments of future generations is ours. To know how to employ it, we should study the law as far as we have opportunity.
This subject is a large one, and no doubt you will some day want to give it a thorough investigation. Just now, however, you will have to accept my statements. I will not make them technical, but strictly practical to you as a young woman desiring that knowledge which shall best fit you for the responsibilities of future life.
A superficial study is rather discouraging. We see with what certainty evil characteristics are transmitted, and we feel that the law is a cruel one; but if we have patience we shall find that, like all laws of God, its purpose is for the benefit of the race. Before we begin to take comfort from the law let us first learn its warnings, one of which is that all weakening of the individual, either in bodily strength, in intellectual power or moral fiber, tends to produce a like weakness in posterity. This is why I say to you that the young people of the present have in their hands the welfare of the future. Their habits to-day are moulding the possibilities of the race. Young women may feel that their individual violation of the laws of health is of no importance, but when theyrealize that the girls of to-day are the mothers of the future, and that the physical strength or weakness of each individual girl affects the average health of the nation, not only now, but it may be through her posterity for centuries, we can see that each girl's health is a matter of national and of racial importance.
But it is not alone in the physical organization that we can trace the law of heredity in the transmission of undesirable qualities. We find that evil traits and tendencies of mind or morals are transmissible. Galton finds that a bad temper is quite sure to be passed on from one generation to the next, and any peculiarity of disposition in either parents is quite likely to become an inheritance of the child. This fact makes our little faults seem of vastly more importance than otherwise. We can endure them in ourselves, but they strike us very unpleasantly when we are obliged to see them manifested in our children. As the poet says:
"Little faults unheeded, which I now despise;For my baby took them with her hair and eyes."
"Little faults unheeded, which I now despise;For my baby took them with her hair and eyes."
It may not strike us very unpleasantly when we speak disrespectfully to our parents, but when our own children show us lack of courtesy and cheerful obedience it cuts deeply, and all the more deeply if we see in their conduct but a repetition of our own.
Of course, if these minor faults are transmissible, we will not be surprised that gravermoral defects are passed on. The grandson of a thief began to steal at three years of age, and at fourteen was an expert pickpocket. The police records show the same family names recurring year after year.
These cases are so grave as to attract attention, while we overlook the fact that the smaller immoralities are as apt to be transmitted, and perhaps with increased power. I should be afraid that slight lack of strict integrity in the father might appear as actual crime in the son.
I would not omit to mention also the law of Atavism, in this discussion of heredity. This is that expression of the law in the omission of one generation in the transmission of a quality. We sometimes see the peculiarities or defects of a man or woman not manifested in their children, but reappearing in their grandchildren.
Not long ago I was in a family where both parents and all the children had dark hair but one, and she had long, bright auburn ringlets. I asked, "Where did you get your hair?"
"From my red-headed grandmother," she answered, with a laugh, indicating that the matter had been so often discussed in her hearing that she understood it quite fully.
To cover the whole scope of the law of heredity would take more time than we have to spare. You can follow out the line of thought, and make practical application of the facts and principles here laid down.
Civilized life in its progress is accompanied by certain customs and habits which are detrimental to the individual health, and therefore to national health. The dress of women is not merely an unimportant matter, to be made the subject of sneers or jests. Fashions often create deformities, and are therefore worthy of most philosophic consideration, especially when we know that the effects of these deformities may be transmitted.
The tightly-compressed waist of the girl displaces her internal organs, weakens her digestion, and deprives her children of their rightful inheritance. They are born with lessened vitality, with diminished nerve power, and are less likely to live, or, living, are more liable not only to grow up physically weak, but also lacking in mental and moral stamina. This weakness may manifest itself in immoral tendencies, or in some form of inebriety. It is now recognized that alcoholism will produce nerve degeneration, but it is not so well understood that nerve degeneration may be a factor in producing inebriates from alcohol or other poisons.
Dr. Crothers says: "Hysteria, convulsions, unreasonable anger, excitement, depression, credulity, skepticism, most unusual emotionalism and faulty reasoning, are some of the signs of nerve degeneration," and adds that this central failure of nerve and brain power is often accompanied by a resulting alcohol or drug inebriety. That is, the weak and degenerate nerves crave a stimulant, and the weak will yield to the demand, and inebriety result. If this degeneration of nerve comes from the low vitality given by the mother, because of her unhealthful habits of dress and life, is it not wise that in her early womanhood she should know of this possibility, and guard against it through her care of herself?
She ought also to understand the effect of alcohol and other poisons in producing nerve degeneration in the individual, and its probability in his posterity.
George McMichaels says: "The hereditary nature of the abnormal condition of which inebriety is the outward sign is not understood, even by physicians, as it should be. It is still, I regret to say, looked upon as a vice acquired by the individual, the outcome of voluntary wrongdoing. In some few cases this may be true, but in the majority of instances inquiry into the family history will reveal the presence of an inherited taint, such families usually showing a neurotic condition. No position inthe social or intellectual world is, or ever has been, entirely free from the tendency towards alcoholism, and a study of the family history of the great men who have fallen victims to alcohol will show that the cause has been identical with the case among the most obscure of mankind, viz.: That a degenerated nerve condition has been inherited which renders the sufferer specially susceptible to this and allied neuroses, such as epilepsy, idiocy and suicide. The inheritance of an unstable nervous system makes the individual easily affected by what I must call 'alcoholic surroundings.' In other words, the provocation to drink which would have no influence upon an ordinary, stable nervous organization, is sufficient to turn the neurotic into a confirmed drunkard."
As a young woman you hold great power over the race in yourself, and through your influence over others, especially over young men. Your influence, wisely used, may save more than one from a drunkard's fate, and to use it wisely you should be instructed as to the real character of alcohol and its effects on the system. I have not time to tell you in minutiæ of the effects of alcohol, but I must take time to speak of the law of heredity in this respect.
Idiocy and inebriety are on the increase among civilized peoples. This startling fact should make us ask the reason.
T.D. Crothers, M.D., who is making a lifestudy of inebriety, states that from 1870 to 1890 inebriety increased in proportion to the population over 100 per cent., and that a large proportion is the result of inebriety in one or both parents. It is a sad fact that many women, even of good social standing, are fond of alcoholic beverages. I saw a very bright, pretty young woman not long since, at a reception, refuse to take ice-cream or cake, but drink four glasses of punch, with many jests as to her fondness for the same, apparently without any glimmering of the thought that she was drinking to excess, although her flushed face and loudness of manner were proof of this to those who were witnesses. Many people have an idea that the finer drinks, such as wine and its various disguises, do not intoxicate, but in this they are mistaken. All alcoholics are intoxicating in just the degree that they contain alcohol. The exhilaration of wine is but the first step of intoxication, and that means always an accompanying lack of judgment, a lessening of the sense of propriety.
One young woman who, under ordinary circumstances, was most modest in deportment, drank at her wedding in response to the toasts to her health, and grew very jovial, until at last she danced a jig on the platform at the railway station amid the applause of her exhilarated friends, who had accompanied the young husband and wife to the train, as theystarted on their wedding-journey. What a sorrowful and undignified beginning to the duties of marriage!
There is no absolute safety for either man or woman except in total abstinence. Thedébauchéknows the effect of wine, and uses that knowledge to lead astray the young girl who, if herself, would find no charm in his blandishments, but who, after the wine supper, has no will to resist his advances.
A young husband exacted of his bride a promise that she would never take a glass of wine except in his company, and when asked the reason, replied that he knew that no woman's judgment was to be trusted after taking one glass of wine.
Another cause of inebriety in women is found in the patent medicines advertised as a panacea for all pain, which chemical analysis shows to be largely alcoholic. Many temperance women would be horrified to know that they are taking alcohol in varying quantity, from 6 to 47 per cent., in the bitters, tonics and restorative medicines they are using, many of which are especially advertised as "purely vegetable extracts, perfectly harmless, sustaining to the nervous system," etc.
The result of inebriety of parents in inflicting injury upon offspring has not been well understood in the past, but is becoming recognized. Dr. McMichael says:
"In every form of insanity the disease is more dangerous in the mother than in the father, as far as the next generation is concerned. This is a good and sufficient reason why the daughter of drunken parents, very often attractive to some men by reason of their excitable, vivacious, neurotic manner, should be carefully avoided by young men in search of wives. The man who marries the daughter of an inebriate not only endangers his own happiness, but runs the risk of entailing upon his children an inheritance of degradation and misery.
"No woman should marry a man who, even occasionally, drinks to excess. Further, the disposition of the sons of drunken parents ought to be investigated before any girl becomes engaged to one of them. This is one instance in which long engagements are not to be condemned, for, if the man has inherited the alcoholic craving, it may become known in time, and hisfiancéemay be saved from the most terrible fate that I can think of—becoming the wife of a drunkard.
"One word more before I leave this aspect of the subject. As the majority of inebriates are sufferers from a disease which is partly the result of hereditary predisposition, it is foolish for any woman to marry a drunkard in the belief that she can reform him. If women would realize that alcoholism is a disease and not avice, they would understand that, while the spirit which prompts their devotion and self-sacrifice is praiseworthy, yet the probability of its success is very remote. No doubt there are women who have made this experiment and who have managed to 'reform,' as it is called, confirmed inebriates; but such cases are by no means numerous. While it might not be right to attempt to interfere with any effort to benefit any representative of suffering humanity, it must be remembered that the fate of the next generation is at stake, and that unborn children certainly have rights, although we are very apt to disregard them. Admitting, then, that anyone is at liberty to risk everything, even life itself, to benefit another, nevertheless it cannot be said that anyone has a moral right to jeopardize the future of a family to satisfy any instinct or feeling of affection, however noble it may be. If what I have written is true, no woman is justified in marrying a drunkard."
The unstable nervous organization bequeathed by intemperate parents is like a sword of Damocles over the heads of their unfortunate children, and even moderate drinkers will not give vigorous bodies and strong wills to their descendants. One man boasted that he had used a bottle of wine daily for fifty years, and it had not injured him; but of his twelve children, six died in infancy, onewas imbecile, one was insane, the rest were hysterical invalids.
And alcohol is not the only substance that inebriates. Opium, morphine, chloral, cocaine, and all drugs of a similar nature, are dangerous, and each not only inflicts its injury on the individual, but transmits its results to posterity in that nerve degeneration which renders the sufferer an easy victim to all forms of intoxication, and intoxication is nothing more nor less than poisoning. Opium and morphine are often prescribed by physicians, and the patient, experiencing the sudden relief from pain, and perhaps not knowing the danger of indulgence, resorts next time to the delightful pain-quieter on his own responsibility, and almost before he knows it the habit is formed, and the weak will that made the easy victim now makes the unwilling slave, loathing his chains, yet unable to break them; and these evil habits are, in their effects, transmitted.
Dr. Robertson says: "The part that heredity plays in all functional diseases or states of the nervous system is not to be misunderstood. It is safe to assert that no idiopathic case of insanity, chorea, hysteria, megrim, dipsomania, or moral insanity, can occur except by reason of inherited predisposition."
The evils of morphinism are even greater than those of alcoholism, and their transmission no less sure. Especially is there loss of moralpower. Dr. Robertson says: "No matter how honorable, upright and conscientious a man's past life may have been, let him become thoroughly addicted to morphine, and I would not believe any statement he might make, either with reference to the use of the drug or on any other subject that concerned his habit. This extends further, and clouds his moral perceptions in all relations of life."
Dr. Brush says: "Cocaine is the only drug the effects of which are more dangerous and more slavish than the inhalation of the fumes of opium."
The danger in the fast life of this age is that we try to find something that will enable us to do our excessive undertakings with less feeling of fatigue. We fail to see in this that we are exhausting our reserve force, instead of adding to our store of force.
ThePopular Science Newssays that kola, cocoa, chocolate, coffee, tea, and similar substances make nervous work seem lighter, because they call out the reserve fund which should be most sacredly preserved, and the result is nervous bankruptcy. Understanding that nervous bankruptcy of the parent threatens the welfare of future generations through the law of heredity, we will surely hesitate to bring ourselves under the strain produced by the use of these substances.
The most dangerous habit of the presentwould almost seem to be the tobacco habit, because it is considered quite respectable and is therefore almost universal. Men who are prominent, not only as statesmen and business men, but also as moral leaders, smoke with no apparent recognition of the evils, and lads can often sanction their beginning of the habit by the fact that a certain pastor or Sunday-school superintendent is a smoker.
But science has not been idle in regard to the investigation of the effects of tobacco, and the discoveries made have been published, so that we are not now ignorant of the tobacco heart, or tobacco throat, or tobacco nerves, nor of the transmission of nerve degeneracy to the children of smokers.
Girls sometimes think it is a great joke to smoke cigarettes for fun, and some grow into the habit of smoking, but the injury is not lessened by the fact that the use of the cigarette was begun in jest, nor that the user is a woman.
In fact, theMedical Timesis quite inclined to assert that much of the neurasthenia, including a general disturbance of the digestive organs, now so common in that portion of the female sex who have ample means and leisure to indulge in any luxury agreeable to their taste, or which, for the time being, may contribute to their enjoyment, is due to narcotics.
During the Civil War we are told that 13 percent. of all men examined were excluded as unfit for military service. We are now told that 31 per cent. are found to be unfit. Nearly one-third of the young men found physically incompetent to be soldiers! From what cause? Certainly tobacco must bear a large share of the blame.
Some years ago Major Houston, of the Naval School at Annapolis, made the statement that one-fifth of the boys who applied for admittance were rejected on account of heart disease, and that 90 per cent. of these had produced the heart difficulty by the use of tobacco.
Dr. Pidduch asserts that "the hysteria, the hypochondriasis, the consumption, the dwarfish deformities, the suffering lives and early deaths of the children of inveterate smokers, bear ample testimony to the feebleness of constitution which they have inherited."
Girls sometimes have the idea that a little wildness in a young man is rather to be admired. On one occasion a young woman left a church where she had heard a lecture on the evils of using tobacco, saying, as she went out, "I would not marry a young man if he did not smoke. I think it looks manly, and I don't want a husband who is not a man among men."
Years after, when her three babies died, one after the other, with infantile paralysis, because their father was an inveterate smoker, the habitdid not seem to her altogether so admirable, and when she herself became a confirmed invalid, because compelled to breathe night and day a nicotine-poisoned atmosphere, she gave loud voice to her denunciation of the very habit which in her ignorant girlhood she had characterized as manly.
There is another influence at work in causing race degeneracy concerning which the majority of girls are ignorant, and that is immorality. The prevalent idea that young men must "sow their wild oats" is accepted by many young women as true, and they think if the lover reforms before marriage and remains true to them thereafter, that is all they can reasonably demand. They will not make such excuses for themselves for lapses from virtue, but they imbibe the idea that men are not to be held to an absolute standard of purity, and so think it delicate to shut their eyes to the derelictions of young men. This chapter of human life is a sorrowful one to read, but to heed its warnings would save many a girl from sorrow, many a wife from heartache.
The law of God is not a double law, holding woman to the most rigid code of a "thou shalt not" and allowing men the liberty of a "thou mayest."
The penalty inflicted for the violation of moral law is one of the most severe, both in its effects upon the individual transgressor and upon his descendants. The most dreadfulscourge of physical disease, as well as moral degeneracy, follows an impure life. This disease, known as syphilis, is practically incurable. It may temporarily disappear, only to reappear in some other form later in life; and even after all signs have become quiescent in the man, they may reappear in his children in some form of transmission. Even one lapse from virtue is enough to taint the young man with this dreadful poison, which may be in after years communicated to his innocent wife or transmitted to his children.
Dr. Guernsey says: "I do not overdraw the picture when I declare that millions of human beings die annually from the effects of poison contracted in this way, in some form of suffering or other; for, by insinuating its effects into and poisoning the whole man, it complicates various disorders and renders them incurable. This horrible infection sometimes becomes engrafted upon other acute diseases, when lingering disorders follow, causing years of misery, and only terminating in death. Sometimes the poison attacks the throat, causing most destructive alterations therein. Sometimes it seizes upon the nasal bones, resulting in their entire destruction and an awful disfigurement of the face. Sometimes it ultimates itself in the ulceration and destruction of other osseous tissues in different portions of the body. Living examples of these facts are too frequently witnessedin the streets of any large city. Young men marrying with the slightest taint of this poison in the blood will surely transmit the disease to their children. Thousands of abortions transpire every year from this cause alone, the poison being so destructive as to kill the childin utero, before it is matured for birth; and even if the child be born alive, it is liable to break down with most loathsome disorders of some kind and die during dentition; the few that survive this period are short-lived, and are unhealthy so long as they do live. The first unchaste connection of a man with a woman may be attended with a contamination entailing upon him a life of suffering, and even death itself. Almost imperceptible in its origin, it corrupts the whole body, makes the very air offensive to surrounding friends, and lays multitudes literally to rot in the grave. It commences in one part of the body, and usually, in more or less degree, extends to the whole system, and is said by most eminent physicians to be a morbid poison, having the power of extending itself to every part of the body into which it is infused, and to other persons with whom it in any way comes in contact, so that even its moisture, communicated by linen or otherwise, may corrupt those who unfortunately touch it."
If girls were aware of all this they would not only be careful how they marry immoral men, but they would shrink from personal contactwith them as from a viper. Not one, but many girls who have held somewhat lax ideas concerning the propriety of allowing young men to be familiar have reaped the result in a contamination merely through the touch of the lips. To-day a young woman in good social standing is a sufferer from this cause. She was acquainted with a young man of respectable family, but immoral life. His gaiety had a fascination for her, and his reputed wildness only added to the charm. On one evening, as he escorted her home, and took leave of her on the doorstep, she allowed him to kiss her. It chanced that at the time she had a small sore on her lip. The poisonous touch of his lips conveyed the infection through this slight abrasion, and she became tainted with the syphilitic virus, and to-day bears the loathsome disfigurement in consequence. I do not need to multiply such cases. You can be warned by one as well as by a hundred.[2]
A young woman of pure life married a man whose reputation was bad, but whose social position was high. To-day she is suffering from the horrible disease which he communicated to her, and her children have died or are betraying to the world in their very faces the story of their father's wrong deeds. Truly you cannot afford to be ignorant of facts so grave as these.
[2]For an extended presentation of the character and diseases which accompany vice, the reader is referred to the chapters which treat of this subject in "What a Young Man Ought to Know." Every young woman should be intelligent upon these important subjects. There is nothing in this book to young men which a young woman approaching maturity may not know, both with propriety and benefit, so that she may most successfully protect herself from possible companionship with well-dressed and polite but impure young men by discreetly placing the book in the hands of her father and brothers, that they may become intelligent concerning the dangers against which they can most successfully protect her. It might not be improper for her, after due acquaintance, to see that the book is placed in the hands of the one who seeks to become her husband and the father of her children, that she may at the proper time, and before it is too late, learn whether he has always lived by the standards of social purity which are there set up, and whether he is able to bring to the union the same unsullied life and character which he expects and requires of her.

I have often heard people say that God was unjust in making this law of heredity and compelling innocent children to bear the sins of the guilty parents, and at first thought it might so seem; but God is a God of justice and also of mercy, and our study of His laws in their ultimate outcome leads us to know that they are invariably made for our welfare. Let us see, then, if we cannot find something encouraging even in this law of heredity. Are the majority of people born straight or deformed, sick or well, honest or dishonest? You may ask, Are all of these conditions a matter of heredity? Certainly. The fact that we are human beings instead of animals, that we have our due proportion of organs and faculties, that we are not monstrosities or imbeciles, are all hereditary conditions. We see, then, that the law of heredity insures to us our full complement of organs and capabilities, as well as the more pronounced characteristics which we the more readily recognize as inheritances. The fact is that inheritance of good is so universal that we fail to think of it.
When the baby is "well-favored" andstraight-limbed, no credit is given to heredity; but if he is in some way out of the ordinary, we blame the law that has fixed on him some result of parental conduct.
If he possesses a good mentality, it scarcely occurs to us that this is just as surely heredity as is the transmission of the mental weakness of some ancestor.
By the Gospel of Heredity I mean this brighter side, this "Good-tidings" of the law. In the first written Biblical record of the law, where the statement is made that the sins of the fathers are visited upon the children to the third and fourth generation, we have also the statement of the "Good-tidings" that the Lord sheweth mercy to thousands of them that love him and keep his commandments; and that means not thousands of individuals, but thousands of generations. Justice is meted to the third and fourth, but mercy to thousands of generations.
All through the Scriptures we find this brighter phase of the law enunciated. Perhaps you would like to study both the law and the Gospel from the Bible. I will give you some texts and you can find them for yourself. It would be interesting also for you to read the lives of men and women of renown, and observe the transmission of talents and capabilities.
Encouraging as this view of the subject may be, it is by no means the brightest side of thesubject of heredity, for if we have inherited no special talents, and if we are handicapped by the transmitted results of the sins of our ancestors, we may say "There is no hope for us, nor for our children." To us then will come, as special "Good-tidings of great joy," the news that heredity is not fatality. We are not obliged to sit and quietly bear the fetters our ancestors have forged for us. We can break the chains, we can free ourselves. It may be difficult, but it can be done, and a great incentive to the effort is found in the fact that by success we not only improve ourselves, but we can pass on a better inheritance to our posterity.
We may cultivate our health by obedience to its laws so as to overcome inherited weaknesses to a very great extent. We are not absolutely obliged to die with consumption because one of our parents did. By simple living, and especially by deep breathing of pure air, we may so strengthen ourselves that we will have the power to resist the encroachments of the germ of tuberculosis.
We may be born with weak digestive power, but by plain, wholesome fare, by freedom from worry, by a careful attention to all healthful habits, we may grow strong and free from dyspeptic symptoms.
We can by cultivation of our minds and morals not only increase our own powers, but add to the powers of our posterity.
Then, too, the effects of mental education are transmissible; not the education itself, but an increased capacity, a new tendency. Every mental activity is accompanied by an actual modifying influence on brain structure, so that we are really building our brains by our thoughts, and this increase of our own brains is transmissible to posterity.
I know that some of our philosophers assert strongly that acquired characteristics are not transmitted, and their theories seem quite plausible; but I would rather accept facts than theories any time, and Professor Elmer Gates has demonstrated that this theory does not accord with the facts. He has trained dogs until they could recognize seven or eight shades of green or red. The brains of these dogs, so trained, show under the microscope a great increase of brain-cells in the visual area, proving that the education has created actual brain material. The progeny of these dogs, to several generations, shows at birth a much larger number of brain-cells in the visual area than is the case where the ancestry has not been so strained.
Where the dogs have been brought up in absolute darkness there is a great lack of cells in the visual area, both in these dogs and in their progeny.
This is the brief statement of a most hopeful and encouraging fact.
We look to the dark side of the law of heredity for our warning. It makes us solemnly thoughtful in view of our power over the race in the transmitted result from our own wrongdoing; and then, when we feel overwhelmed and discouraged, we turn towards the Gospel of Heredity and take hope from the fact that good is transmissible; and, more than that, we have it in our power so to modify our own characters, tendencies and habits that we can, in all probability, give our children a better dower than we received, and the earlier in life we begin this making over of ourselves the better.
I have heard people excuse themselves for all manner of faults on the plea that they were inheritances, and therefore could not be overcome. That is to declare that we are slaves, with no chance to acquire freedom, and I am not willing to admit that.
"Whereas in Adam all die, in Christ may all be made alive." That is, that while under the Law of Heredity we are fettered, under the Gospel of Heredity our chains may be broken and we become free.
There is much of encouragement in the poem of Ella Wheeler Wilcox on heredity:
"There is no trait you cannot overcome.Say not thy evil instinct is inherited,Or that some trait inborn makes thy whole life forlorn,And calls for punishment that is not merited."Back of thy parents and grandparents lies[246]The great Eternal Will, that, too, is thineInheritance—strong, beautiful, divine;Sure lever of success for one who tries."Pry up thy fault with this great lever—will;However deeply bedded in propensity;However firmly set, I tell thee firmer yetIs that great power that comes from truth's immensity."There is no noble height thou canst not climb;All triumphs may be thine in time's futurity,If, whatsoe'er thy fault, thou dost not faint or halt,But lean upon the staff of God's security."Earth has no claim the soul cannot contest;Know thyself part of the supernal source,And naught can stand before thy spirit's force;The soul's divine inheritance is best."
