Chapter II: Introduction: To Points on Practise (1)

The preceding lessons were written through a period of many years' active practise in treating dis-eases by scientific feeding. They were intended as a normal course to qualify doctors, nurses, and those who wished to treat dis-ease by this method. However, the demand for this class of information has come from people in every walk of life, therefore the lessons, and all technical matter composing this entire work have been most carefully revised and rewritten in simple language so that any person of ordinary intelligence can comprehend them.

The following lesson is intended for the guidance of the practitioner in beginning his work in this branch of the healing art.

Inasmuch as nearly all human ills are caused by errors in eating, the preceding lessons have been confined almost wholly to dis-eases that originate in the digestive organs.

Lesson XVIII

POINTS ON PRACTISE

[Sidenote: Dietetic treatment is reconstructive]

There are a great many abnormal conditions of the human body classed as dis-eases that bear a very remote relation to diet, but in practise the student will soon learn that many of these conditions, which have not been considered in these lessons, will entirely disappear when the diet is perfected. This is true because dietetic treatment, based upon the fundamental laws of nutrition, is reconstructive, hence every part of the anatomy shares in the general improvement.

[Sidenote: Scope of scientific feeding]

There are many logical arguments to support the theory that there are no incurable dis-eases. There are many cases, however, where the vitality has become so low that recovery from dis-ease is impossible, but if the patient could be taken in time, the correct diagnosis made, and the proper food, air, and exercise given, Nature would begin her work of rebuilding at once. In view of these facts it is somewhat difficult to fix a limit to the scope of scientific feeding.

SUGGESTIONS FOR THE PRACTITIONER

[Sidenote: The value of letters]

The science of prescribing diet is a work that can be best conveyed to the patient in writing, hence one of the first and most important things for the new practitioner to do is to study the art of polemics--acquire the ability to write plain, convincing literature and letters. This is one of the greatest arts within the scope of human learning, and is probably susceptible of greater development than any other branch of human endeavor.

Every person has his own individual method of expression that should be preserved and cultivated. Select some good author and copy his logic, but not his language. For this purpose I would recommend the works of Henry George, the great economic philosopher--and probably one of the greatest polementitians that ever lived.

[Sidenote: Writing is mental calisthenics]

The student should begin by taking up some simple branch or certain subject of his work, and writing a short argument or essay upon it, using every fact that he can possibly command to convince imaginary readers of the correctness of his theories. Select a new subject and write something on it every day. This is merely mental calisthenics, and after a month's training the thoughts and the language will flow with a freedom that will enable the student to write just as he feels.

[Sidenote: A booklet describing your work]

It would be well to arrange an argument based upon each lesson separately, dividing it into short chapters. These arguments or essays should be logically arranged to form a booklet, with proper title, as such representative literature is vitally necessary to the growth and the success of your work. It will also be found that this will be splendid mental exercise, and will serve well in presenting your work, either orally, or by letter.

[Sidenote: The personality of the writer]

Every one should endeavor to be original in his literature; in other words, no special effort should be made to quote any "authority" or to copy the style of other writers. Put your own personality into your work, for the most successful writer is not always the one who uses the most learned, polished or scholarly language, but the one who can convey his thoughts to the minds of others in the simplest and the most comprehensive language.

Language at best is but a vehicle for conveying the thoughts of one person to the mind of another, and while there are accepted standards in literature and letters, from which one should not make too radical a departure, yet the ability to present one's convictions, or position convincingly should be of first consideration.

The most important thing in writing is to have something to say; then to say it so that it can be understood.

VALUE OF EXPERIENCE

Experience is the only method by which theory can be converted into knowledge. The best possible source of information, therefore, is personal experimentation. If the student should have any disorder, especially of digestion and assimilation of food, or elimination of waste, he should experiment upon himself along the lines laid out in this course. He should keep an accurate record of selections, combinations, and proportions of food, with results or symptoms. He may thus be able to arrange menus for himself, even more effective than those given as examples or guides throughout the course.

If there are no personal disorders that will permit of such experiments, then they should be made upon some other person with whom the student is sufficiently familiar in order that accurate information concerning the results may be secured.

Though the student may be normal and healthy, it is possible to make many valuable experiments in regard to special adaptations of diet, such as combinations to induce natural sleep; to produce and to relieve constipation and diarrhea; to produce excessive body-heat when exposed to cold, or the minimum of heat in summer, or in warm climates.

VALUE OF DIAGNOSIS

Correct diagnosis is one of the most important factors in the practise of applied food chemistry, and when a correct diagnosis has been made the remedy will suggest itself if the student has a thorough understanding of causes.

[Sidenote: Causes sometimes very remote]

In diagnosis it is often necessary to ascertain the patient's general habits of eating during the few years prior to the appearance of the disorders. As an example, rheumatic conditions are often superinduced by an overconsumption of starch, usually cereal starch and acids. This overindulgence may have continued for several years before the appearance of any rheumatic symptoms. The primary causes being residual in the body, exposure, low vitality, or extreme climatic changes may give expression to them in the form of rheumatism, or some kindred trouble.

[Sidenote: Value of limited feeding]

After determining the causes, a diet should be designed which will counteract existing conditions. This may usually be accomplished by limiting the quantity of food somewhat below the demands of normal hunger. This will give the digestive organs less work to do, and the body an opportunity to take up or consume any excess of food matter that may have become congested. In cases accompanied by loss of hunger, it is sometimes necessary to put the patient upon an absolute fast from one to three days, but in the majority of cases a semi-fast is best, prescribing light, nutritious foods of a remedial character.

EDUCATE YOUR PATIENT

In beginning treatment each patient should be made acquainted with the fact that the radical change in diet may bring slight discomfort. While the system is adjusting itself to the new regimen, there is usually a slight loss of weight and a feeling of weakness or lassitude.

[Sidenote: Curing a slow process]

It should be impressed upon the mind of the patient that regaining health and strength is in reality a process of growth or evolution, hence slow and gradual; that when one has violated the laws of health for many years, Nature will not, or probably cannot forgive all these sins and repair all these wrongs in a month or two. However, when one gets in harmony with the physical universe, and conforms to the laws of his organization, Nature will construct (cure) much more rapidly than she formerly destroyed (produced dis-ease).

[Sidenote: The patient should agree with the diet]

The practitioner may have many cases that for some seemingly mysterious reason will not respond to a perfectly natural diet and will, therefore, be called upon to change the diet from time to time in the vain hope of finding combinations of food that will agree. In these cases the student should not be led to deviate too far from what he knows to be a natural and chemically harmonious regimen. If such a diet does not produce the desired results, it is not always the fault of the food, but the fault of the patient. If the food is right, and does not agree, it is the patient that is wrong, hence the logical thing to do is to make the rebellious patient agree with the food, instead of searching for a food to agree with the patient.

These facts should be impressed strongly upon the mind of the one under treatment, and he should be prevailed upon, if possible, to conform strictly to a correct diet until Nature is given time and opportunity to bring about an adjustment between the individual and his food.

It has been the custom of the medical profession for centuries to shroud its work in mystery, to write prescriptions in a dead language, to keep patients in ignorance of the remedies being applied. This seems to be necessary, probably because an intelligent discussion of allopathic drugs, their sources and their constituent elements would, no doubt, prove fatal to their administration. The food scientist should follow exactly the opposite course. He should make a very careful diagnosis, taking into account the diet, habits of exercise and exposure to fresh air prior to the appearance of the dis-ease, as well as at the time of treatment. By giving the patient a thorough understanding of your work, you gain his confidence and faith, which wield a very powerful influence over the body.

EFFECT OF MENTAL CONDITIONS

[Sidenote: Worry or fear causes stomach trouble]

A very careful examination should also be made of the mental conditions. Worry, fear, or anxiety often produce serious digestive trouble which is generally attributed to other causes, and which should be treated very differently from the same trouble caused by errors in eating.

During my professional work many patients have come to me laden with fear, caused by the thoughtless or perhaps reckless statement of some physician. It is indeed as great a crime for a doctor to pass the "sentence of death" upon a man who comes to him for help as it would be for the judge of a court to pronounce the death sentence upon a prisoner without hearing the evidence, and some day when the power of the mind or suggestion is understood, it will be so considered.

[Sidenote: What Christian Science has done]

It is impossible to fully estimate the effects of fear on the human body. Each year, I become more and more impressed with the fact that fear is one of the most potent factors in the cause of dis-ease. Christian Science has relieved thousands of people through the simple presentation of a philosophy that induces the individual to throw off this burden of fear. It matters not whether this burden is cast upon the Gentle Nazarene or John Doe, the fact that it has been disposed of often leads to relief and recovery. Christian Science has done the world a great service--it has put out the fires of an orthodox hell by pouring into it orthodox medicine.

With a clear knowledge of the powerful psychological law, and the laws of human nutrition, the student has at his command two of the greatest forces in Nature for the relief of human suffering.

PUBLICITY

[Sidenote: Value of truthful advertising]

Judicious and truthful advertising is another important factor in the success of the food scientist. Advertising has been considered unethical by medical men for years. It has been discredited, not because it is wrong, or because there is any harm in telling the public the truth about one's business, but because so many spurious nostrums and patent medicines were exploited by "quack" doctors, that the respectable physician deemed it best to adopt the other extreme in his effort to keep entirely out of this class.

Advertising, however, is rapidly acquiring a more honest and upright character. The best magazines and some weekly newspapers will no longer accept advertisements of a questionable character, especially regarding medical remedies. Many of these excellent publications go so far as to vouch for and guarantee the honesty of everything exploited in their pages. Such methods are gradually purifying the advertising atmosphere.

[Sidenote: Advertising both virtuous and necessary]

There is no logical reason why anybody who has a virtuous and useful article, or who has discovered anything in the realm of science that would be a benefit to humanity, as well as a profit to himself, should not make it known as widely as possible through the instrumentality of advertising.

In preparing advertising literature, whether for magazines, booklets, or letters, facts and truth concerning your work are all that is necessary. No statement should be made that can in any way jeopardize your reputation; nothing should be stated or claimed that cannot actually be made good.

For many years it has been my policy to keep my advertising conservatively below the full limit of facts; in other words, the whole truth concerning that which can be accomplished by scientific feeding sometimes seems so startling to the lay mind that the experienced advertiser will not state it as it really is.

A patient of mine who had been in a wheel chair for twelve years, and afflicted for twenty years with locomotor ataxia, was so much improved within a year's time that he walked from Brooklyn to my office in New York City to exhibit himself. He gave me a testimonial letter and the privilege of using it in my advertisements. I wrote up the facts in regard to his case and submitted them to my agent, who was an expert advertiser, and he advised me not to state the facts as they were; the public, he contended, would not accept them as true.

BE COURTEOUS AND TOLERANT

It is almost impossible to estimate the moral effect of a broad-minded, tolerant and courteous attitude toward others engaged in the practise of the healing art. Medical doctors seldom agree, especially those of different schools. They accuse each other of ignorance and incompetence, and the public is sometimes inclined to concede that they are right.

In certainty and in truth one has confidence and strength which is always conducive to tolerance. The food scientist, knowing the laws of cause and effect in regard to nutrition, and knowing the proper use of natural methods of diet and hygiene in the prevention and the cure of specific dis-eases, needs neither to dispute with a fellow practitioner, nor to argue with his patient. He can afford to state his position and quietly allow Nature to prove his claims.

LESSON XIX

EVOLUTION OF MAN

The following lessons, while they do not treat directly of either the chemistry of food or the chemistry of the body, are so closely allied to these subjects that this work would not be complete without them.

LESSON XIX

EVOLUTION OF MAN

WHAT IS EVOLUTION?

If a resident of a city, who is not familiar with modern farm machinery, should see a grain-binder at work, he would be impressed with the skill and the ingenuity of man. In all probability he would think that the machine was the product of one inventive mind. In this, however, he would be mistaken. The reaper in its modern form is the result of gradual development or growth.

[Sidenote: An example of evolution]

The earliest method of gathering grain was pulling it up by the roots. Later, as cutting tools were invented, a rough knife was used to sever the stalks just above the ground. An improvement upon this method was the cycle; then came the scythe, then the cradle; and next came the mower which was operated by horse-power. From the mower was developed the self rake, which bunched the grain so that the hand-binders could work with greater facility. The next improvement was a self-binding machine. In the present machine we have all of these and many other improvements, which give greater speed with less waste of labor and time.

This development of the grain-binder is a process of evolution. In order to understand a machine so as to use it intelligently, or to make improvements upon it, it is necessary not only to know the machine as it actually is, but also to know the history of its development up to its present form.

[Sidenote: To know man is to know evolution]

The story of the evolution of a machine is, at best, but a crude illustration of the evolution of man. Nevertheless, the conclusion is the same. If we are to understand man, we must study not only his present physical and mental state, but also the history of his development. Yet those whose work is concerned directly with man--whether they be teachers, guiding the growth of the child; statesmen, formulating the laws and regulations by which men are to be controlled in their public actions; or physicians, who are supposed to instruct and to guide men in the care of their physical well-being--are often densely ignorant of the most rudimentary knowledge of the evolution of man as it is now known and understood by the leading scientists of the world.

Our entire system of education, our ideas of health and dis-ease, our social customs, the principles of our form of government; our ideas of right and wrong, of rewards and punishments, are all fundamentally concerned with the evolution of man, and when this knowledge is studied with as much application as are the ancient languages, we may expect to see humanity progress at a rate hitherto unknown.

[Sidenote: Significance of the term "evolution"]

The evolution of man has been very much misunderstood. The term "evolution" is a broad one. It may refer to the growth of the individual, or to the race. It may mean the development of strictly physical organs, or of mental habits, of social customs, or of material products of man's genius, as the great works of civilization in the form of recorded learning, and the wonderful products of man's building ingenuity as seen in modern cities.

The subject of the evolution of the human race may be grouped into three general kinds of development or growth:

1 The development of the physical man

2 The development of the mind

3 The development of custom and of external civilization

Evolution in these three directions has taken place simultaneously. The mind and the body depend upon each other for their life and actions; while customs are merely the product of many minds working together and communicating their ideas to each other.

* * * * *

The human race is but the sum of the individuals composing it. We cannot consider the development of the individual without considering him in his relation to the race, neither can we understand the development of the race without understanding the growth of the individual.

[Sidenote: Difference between inherited and acquired characteristics]

One distinction too often overlooked by those who are not familiar with physiological science is the difference between actual physical inheritance and external customs. I wish to dwell at length upon this distinction, because a lack of understanding upon this point has been the source of many errors of judgment on the part of those who have been interested in the subject of physical training and food science.

At birth the individual inherits an organism with certain tendencies, both physical and mental, but this inheritance should not be confused with the physical habits which the child acquires by training from its parents and its associates. Thus, the child may inherit a brilliant mind, a weak stomach, or a sixth finger, but the child does not inherit a liking for broiled lobster, or a fondness for golf, or for driving an aeroplane. These are acquired and developed as habits, the same as the child would learn English or French, or would cultivate a fancy for parting his hair in the middle, or on the left side.

THE THREE GREAT PROOFS OF THE EVOLUTION OF ANIMAL LIFE

At the present time scientists are agreed upon the general theory of the evolution of man. The discussions pro and con regarding this, which exist today, are either discussions of minor points which have not yet been clearly worked out, or are the discussions of people who have grasped only a portion of the idea of evolution, and who are ignorant of its broader conception and of the facts which science has brought to the light of day.

The three great proofs of evolution are:

1 The actual history of the past recorded as fossils in the rocks
and in the relics of pre-historic races

2 The existence in the world today of a range of animals and plants
which shows living examples of earlier types

3 The repetition of the development of man as found in the growth of
the individual

These three separate records of the development of living beings are considered by scientists as a most conclusive proof of the truth of evolution. Recorded as fossils in the rocks, we find the story of the development of all life upon the earth, from its simplest to its highest forms of plants and animals that live today, among which is man.

[Sidenote: The earliest forms of animal life]

The first forms of animal life were, in all probability, minute one-celled organisms; these left no visible fossil remains. As soon as animals developed hard parts in their bodies, such as shells and bones, we find a record of their existence as fossils. The earliest recorded forms of life were various kinds of sea-creatures, of which the modern crustacea (lobsters, etc.), snails, clams, and various shell-fishes are types. Later were developed boneless fishes, on the order of skates. After these came true fishes; then amphibia (frogs, etc.); then reptiles, birds, and, last of all, mammals, including man.

The facts are the same, whether we take the history of the successive forms as recorded as fossils in the rocks, or the living representatives that remain to tell the story in another form.

[Sidenote: The single cell is the nucleus]

The third proof, which is the story of evolution recorded in the growth and development of the individual, is yet more interesting. As life developed from simpler forms, each individual animal or plant became more complex, or carried a little further the process of growth. But the method of reproduction of new individuals remained fundamentally the same. Each individual began, like its ancestors, as a single-cell being. By the process of nutrition these single cells in each case would grow, divide, and produce various tissues and organs, but always repeating the general story of the development of the race.

[Sidenote: Gills in the human embryo]

The growth of the human embryo offers many proofs of evolution, which are wholly unexplainable upon any other theory of the origin of man, and would in themselves prove the truth of this view of man's creation were the proofs of geology entirely lacking. A single example will serve as an illustration. The human embryo at a certain period develops gill slits in the neck, the same as the embryo of a fish. This formation of unused or rudimentary organs which are afterwards outgrown, is very common throughout the animal world. In the upper jaw of a calf there are formed at a certain period incisor teeth, which never grow through the gums, but are reabsorbed and disappear as the calf develops.

I will not go further into the proofs and facts of the general theory of the evolution of animal life, but will now consider the later period of the development of man, which will show us his relation to other animals, and from which we can derive much valuable information regarding his natural physiological requirements.

MAN'S ANIMAL KINSHIP

The conception of man being descended from a monkey has been the subject of much wit and mirth.

[Sidenote: Man's relation to anthropoid apes]

The scientist is not concerned with this theory; he only claims that man is very closely related to certain monkey-like forms known as anthropoid apes. The proofs of this assertion are abundant and conclusive. In fact, anthropoid apes, such as gorillas, chimpanzees and orang-outangs, are much more closely related to man than they are to other kinds of monkeys. This relation is shown by very close resemblance between the anatomy of man and apes, especially as to the teeth and digestive organs. Other facts are now known, of which Darwin and early investigators were ignorant, which prove this relation in a much more striking manner.

[Sidenote: Comparison of blood from man and apes]

Late studies upon the growth of the embryo of anthropoid apes have shown that they were at certain periods almost indistinguishable from human embryos. Another proof, quite striking and interesting, is in the similarity of the parasites and dis-eases of men and apes. Scientists have, within the past few years, made a series of comparative investigations upon the blood and serum of men and apes, which have resulted in most remarkable discoveries. There are certain accurate tests known to the physiological chemist by which human blood may be distinguished from the blood of all other animals, but the blood of these man-like apes is an exception to this, and cannot be distinguished from human blood.

[Sidenote: Difference in the development of man and apes]

From these facts it is clear that the earlier types of men were creatures whose physical development and whose habits were not very different from those of apes. The development that has taken place since that time is truly very wonderful and has resulted in a widening gap between man and apes that today seems very great. The truth remains, however, that this gap is not so much one of anatomy and physiology as it is one of mentality and of external habits and material aids to living that have resulted from man's greatly developed mental faculties.

[Sidenote: Power of speech a factor in man's evolution]

Thus, when the mind of man reached the stage of development in which the use of articulate speech became possible, the evolution of intelligence proceeded at a very much more rapid pace than had been possible before. He could communicate his ideas to his fellow-creatures; concerted action became possible, and the faculty of reason, or the ability to think was multiplied by the number of beings who could communicate with each other.

The power of reason and the ability to communicate ideas resulted in the formation of those habits which distinguish man from other animals. When one primitive man learned the use of a club as a weapon, found how to use sharp-edged stones as cutting tools, or discovered the wonders and power of fire, he communicated his new-found knowledge to the other members of his tribe, with the result that new ideas became common property.

[Sidenote: Man's bad habits have kept pace with his progress]

This spreading of habits or customs took place very rapidly among men and was the source of the various changes which distinguished civilized life from savage life. But we must here point out that not only good habits were so spread, but bad ones as well. The origin and the use of opium and of alcohol, the injuries of fashionable dress and the economic wrongs of tyrannical government originated along with the birth of language, art, science, and all that uplifts and benefits mankind.

Clearly, then, that man is misinformed who defends a wrong by referring to its age and reasons that, if certain things were harmful, they would not have survived. To the young thinker the existence of harmful ideas and habits among mankind may at first seem inconsistent with the principles of the survival of the fittest, but this difficulty will disappear upon further investigation.

[Sidenote: Factors that determine the survival of races]

Since the beginning of recorded history many factors have helped to determine what kind of individuals and races should survive. War, economic wealth and poverty, intellectual beliefs, religions, and social institutions have all been potent factors in determining who should survive. With wealth and conquest came the opportunity to gratify tastes and passions of which the poor individuals of weaker races could not avail themselves.

[Sidenote: Many habits and customs detrimental to life and health]

Many of the habits and customs which man has developed are not necessary to life, and may be positively detrimental to health and longevity. They have been handed down from generation to generation, not because of their benefit to man, but in spite of their detriment.

Such condition of affairs would not be possible if man were not the dominant animal. Man's intellectual supremacy has given him power over the rest of nature, which has resulted in making his struggle for existence much less severe. His use of weapons and of artificial protection from natural destructive forces, as severe heat or cold, has made it possible for him to live and to produce offspring in spite of wrong habits and wrong methods of living, and the natural resistance of life.

[Sidenote: Man's organs have a limited power of adaptation]

A prevalent error that is due to an incomplete knowledge of the facts of evolution is the belief that organs readily change or adapt themselves to the habits or environment of the individual. This is not true to the extent that it is ordinarily believed. Each individual has a certain limited power of adaptation. He may develop his lungs to a greater breathing capacity, or train his hand for certain skilled work, but these particular acquired habits of the individual are not inherited.

Evolution of the race proceeds by the law of natural selection. Thus, if those who are born with great vigor and strong lungs are enabled to live where their weak-lunged neighbors will die, the result will be that their offspring, having greater lung capacity, will form a race with increased lung capacity. But the individual training of the lungs, or of the hand, or of any other organ of the body, will not of itself change the inherited tendency, or, to use a common term of the scientist, the germ-plasm of the race.

Organs and functions will change or become evolved by natural selections; that is, where it is a matter of life and death. But where the selective agencies depend upon other things, an organ may be used or abused for thousands of successive generations, and yet the natural inherited organ of the new-born child will be identical in development and function to that of the remote ancestor.

[Sidenote: Acquired characteristics are not inherited]

There are abundant proofs that so called "acquired characteristics" are not inherited. Were acquired characteristics inherited, Chinese women would be born with small feet and the babies of the Flathead Indians would inherit the flat head which has for generations been produced by binding a flat stone on the soft skull of the new-born infant.

In the light of this fact we may understand how it has been possible for man to live through the varying dietetic habits and customs that the constantly changing ideas and tastes of civilization have thrust upon his physical organism. Each individual has transmitted to his offspring the same type of digestive organs and functions that he himself inherited from his remote anthropoid ancestors.

[Sidenote: Meaning of expression "natural" diet]

Thus, such terms as "back to nature," "natural diet," etc., only mean to the food scientist the habits of life or the dietary which is most suited to the unperverted physical organism of man. They do not imply the meaning that is popularly given to the term, of casting aside all the habits and customs of civilized man, but only the adapting of these customs to the inherited physiological organism of man.

Indeed, science may actually improve upon primitive conditions, and still not be inconsistent with the requirements of the inherited physiological machine. No intelligent man will dispute the advantage of a house in a snowstorm. Yet the house is artificial. It is not "natural" in the sense that the term is commonly used.

Or, again, man has by the aid of civilization rendered it possible for us to use foods far removed from their source of production, or, by preservation, to have them at seasons of the year when nature does not provide them. These artificial results of civilization are good. They are a part of the story of evolution, the benefit of which no one can question.

[Sidenote: Man's dietetic development]

But the great majority of the dietetic "frills" of modern man are actually unsuited to his physiological make-up, and exceedingly harmful. They have been developed as have habits of drink or personal adornment and may be in direct antagonism to the ultimate well-being of the human race.

I have briefly reviewed the history of the evolution of man. The facts to be remembered are:

1 That men are descended from earlier and more primitive types of
beings and are governed by the same general laws of heredity and
nutrition as are other forms of animals

2 Man, being a distinct species of animal, has particular laws that
apply only to him, and therefore we should be careful not to judge
him too closely by facts regarding other forms of animal life

3 Man has changed very materially in the few thousand years of his
civilization, in his external habits and customs, but very little in
his fundamental physiological processes; therefore we should be able
to judge what will be best suited for his needs by studying the
process of the development of his organs during the millions of
years that preceded the historic period. This plane of life is best
seen today in the case of savages unacquainted with fire, and in the
case of anthropoid apes.

With this general survey of evolution, and a clear understanding of the principles involved, I trust the reader will consider the facts here presented in the unprejudicial spirit of the true scientist.

LESSON XX

SEX AND HEREDITY

THE ORIGIN OF SEX

That part of human life and living that is associated with the functions of sex and reproduction is at once the cause of the world's greatest misery and the world's greatest happiness. It is the subject of the greatest popular ignorance and superstition, and at the same time the field of the most wonderful of all scientific knowledge.

For the origin of sex we must look back into the remote ages of creation in the early stages of organic evolution.

[Sidenote: Fundamental function of the cell]

The first essential property of matter that makes life possible is the power of nutrition, which means the ability of the living cell to transform other chemical substances into its own protoplasm or living substances.

But this world would have remained a barren mass of igneous rock if nutrition had been the only function with which the earlier forms of life were endowed. Not only must the living cell be enabled to grow by absorbing other substances, but it must reproduce itself, or multiply the number of living individuals.

[Sidenote: First form of reproduction]

The first method by which this was accomplished was undoubtedly one of simple division; that is, the living cell grew by absorbing other substances and when sufficient size had been attained, divided, forming two daughter-cells. This division process of reproduction is the form by which all bacteria (so-called dis-ease germs) and many other lower forms of life increase their numbers.

[Sidenote: Second form of reproduction]

[Sidenote: Strength in fusion of cells]

This process of reproduction, by simple division, was early supplemented by another process of reproduction in which two living cells first fused or combined and then divided to form two or more daughter-cells. This form of reproduction seems to have added stimulus or vitality to the organisms. The supposed reason for this is that the isolated cell was inclined to weaken or lose its chemical balance or tone. The exact nature of this deterioration is not very clearly understood, but in a higher form of life it is well illustrated by the tendency of certain plants to "run out" when grown continually in the same soil, or of animals to become weakened when inbred. At least, all scientists concede that with the process of fusion or the combining of two cells there is added a stimulating and invigorating force which enables life to combat more successfully the unfavorable elements of its environment, and to change or evolve into higher forms.

[Sidenote: Sexual reproduction in plants]

[Sidenote: Fertilization of orchids]

Throughout the range of plant and animal life this process of cell union, or sexual reproduction, has grown and become elaborated into most varied and wonderful forms. Large volumes could be written describing the many wonderful adaptations of plant and animal life, the purpose of which is to secure sexual reproduction. All those who have studied botany are familiar with the many ways in which the seeds of plants are fertilized by pollen. For instance, certain species of orchids have a receptacle in the blossom, shaped like a teapot, which is filled with a fluid resembling water. This little teapot has an entrance and an exit. Near the entrance is sweet-scented nectar which attracts the bee. As the bee passes through this gateway he is tripped up on a little trap-door arrangement and precipitated into the fluid. His wings having become wet, he is obliged to crawl out through the exit.

[Sidenote: The wonderful process of flower fertilization]

The object of this elaborate device is as follows: In the entrance passageway is located the stigma (female organ), while in the exit passageway the male or pollen-bearing organ of the orchid is found. The bee visits several of these flowers consecutively, and, as he makes his exit from each flower, he bears away on his body a portion of the pollen, which is transferred to the stigma of the next flower visited; while the bee, being forced to go through a "plunge bath" before visiting another flower, acquires a fresh load of pollen in each case. This scheme is a certain means of securing fertilization or sexual reproduction, and positively prevents inbreeding (the fertilization of a flower by its own pollen). This is merely one of the wonderful adaptations of nature in the solution of the sex problem.

[Sidenote: Reproduction among fishes]

[Sidenote: Nature's wasteful methods]

In the animal kingdom the methods of sexual reproduction are also varied and wonderful. In many of the lower forms of animals, such as the various sea-creatures, the methods of reproduction may be those of division, as first mentioned, or a method combining division with true sexual reproduction. In the case of fishes, the eggs of the female are deposited in the bottom of a stream and are later fertilized by the sperm-cells of the male fishes. This involves a tremendous waste of reproductive cells, scarcely less extravagant than the waste of pollen in plants, such as is seen in a corn-field when the ground becomes yellow, during the tasseling season, with the myriads of pollen grains that failed to secure lodgment upon the silks of the young ears of corn.

[Sidenote: Reproduction in higher forms of life]

In the types of animals that are of higher form than fishes, that is, reptiles, birds, and mammals, the fertilization of the germ-cell (egg) takes place within the body of the female. In the case of the latter group--mammals--the true egg is hatched within the body of the female, and the offspring, or embryo as it is known to scientists, grows there for a considerable period before birth.

A RATIONAL VIEW OF SEXUAL HEALTH

The anatomy and the physiology of reproduction will not be considered in detail in this work, as this would require a very lengthy and technical treatise. The remainder of the lesson will be devoted to the relation of the reproductive functions to general health and happiness.

[Sidenote: Development of reproductive instincts]

In the process of evolution this function of reproduction was vitally essential to the life of the race. As a result there developed in all animal life strong sexual or reproductive instincts. As is plainly evident, all animals, including man, with such instincts most strongly developed would be the most successful in producing young, and through these offsprings the race or species would inherit like reproductive desires.

[Sidenote: Kinship of the sexual, paternal and social instinct]

In the case of man and the higher form of animals, this general instinct, the purpose of which was to produce offspring, became diversified in to many instincts. Not only does the reproductive instinct in this broad sense include what is commonly known as sexual passion in man, but it may very truly be said to be the essence of sexual love and parental love. Broad-minded scientists are even inclined to believe that the so-called social instinct or love for our fellowmen is but a distant reflection or shadow, as it were, of the original or natural instinct to produce offspring.

There has arisen among civilized man a tendency to separate and class as two distinct things the strictly physical element of sexual desire, and the associate emotion of intellectual love between the sexes. As a matter of fact there is no distinct line of demarcation.

[Sidenote: Overindulgence, degenerating and destructive]

That the former instinct has grown into disrepute and has come to be considered a forbidden topic in polite society, is due to the fact that sexual passion, like all other human acts which may be a source of gratification, can degenerate by overindulgence into a destructive and demoralizing vice. This is equally true of other forms of appetite, but the reason that the instinct of sex, when degenerated, becomes such a tremendous source of destruction and death is because of the important part played in the game of life by the reproductive function.

[Sidenote: Relation of sexual functions to the nervous system]

The functions of reproduction are, in both sexes, very intimately and closely associated with the nervous or vital mechanism of the entire body. For this reason, when the sexual function are perverted or abused the result is serious injury to the general nerve tone or vital force of the system. Likewise the contrary proposition is true; therefore, when for any reason, the general nervous tone or vital force of the body is deranged, the associated result is frequently abnormal passion or weakened sexual functions.

[Sidenote: Necessity for popular knowledge concerning sex]

A great deal of literature has been written and circulated throughout the country by well-intentioned individuals purporting to give popular knowledge regarding the subject of sex. But such literature has greatly exaggerated the evils and the dangers connected with sexual health. Outside of specific germ dis-eases transmitted through the sexual organs, and which, while serious, have been painted much darker than the facts justify, there is little excuse for all this horror and scare about sexual weakness and perversion.

[Sidenote: Relation of nutrition to sexual health]

Sexual health, like mental or muscular health, is a matter of common sense and right living. Proper feeding, proper oxidation, proper circulation (exercise), perfect elimination of waste-products, and a suitable distribution of both mental and physical work will result in perfect nutrition. This means normal, wholesome body-fluids and body-cells. With these things gained, the sexual organs and sex-function will have a fair opportunity for normal existence, and the matter of sexual health, and the consequent happiness which accompanies it, is then simply a matter of temperance, common decency, and self-control.

EMBRYOLOGICAL GROWTH--PRENATAL CULTURE

[Sidenote: Superstition concerning prenatal culture]

Upon the growth of the human embryo, or so-called prenatal culture, there exists a great deal of popular superstition, which is utterly groundless from the standpoint of accurate science. The views that have been promulgated regarding prenatal culture are for the main part harmless, and, for that matter, may be productive of good.

[Sidenote: Theory of prenatal culturists]

The idea of the prenatal culturist is that the mental as well as the physical growth and development of the unborn child can be controlled by the mother. The only ground for this belief is as follows: The child is nourished from the blood or nutritive fluid of the mother, with the result that the growth and the development of the child may be very readily influenced by the nutrition of the mother.

[Sidenote: Influence of fright, anger, etc.]

The mental condition of the mother has an influence on the growth of the child, but it is indirect. All organs and functions of the human body are controlled by the nervous system, and if the nervous impulse be deranged or weakened it may result in a serious impairment of nutrition. For this reason fright, anger, and other strong passions may result in lasting injury to the unborn child, but this injury is at most a matter of stunting or malnutrition, and cannot result in the voluntary mental life of the mother being transmitted to the child.

[Sidenote: Mother's nutrition the only factor in influencing her child]

As evidence of these assertions, I would call the reader's attention to the fact that there is no nervous connection whatever between the embryo and the mother, but after the fertilization of the germ-cell, the only way in which the mother can influence the growth of the child is by the nutrition which her blood supplies to the growing tissue of the embryo.

[Sidenote: Birthmarks]

As further proof of these statements, I will cite the investigations of Darwin in regard to the popular superstition of birthmarks. At the instance of Mr. Darwin, some seven or eight hundred women of a London hospital were very carefully questioned before the birth of the child, as to any incidents which had happened that, according to popular notions, might result in birthmarks or deformities. In no instance was any incident given which resulted in the expected deformity; but the most interesting feature of the investigation was that several women whose children were born with birthmarks recalled, upon seeing the deformity, some incident which seemed to give a possible explanation, thus showing to the mind of anyone familiar with psychology that the true explanation of all so-called remarkable incidents of birthmarks and of prenatal influence is merely one of superstition or self-deception.

HEREDITY

How often we hear someone remark upon the wonders of heredity. People are astonished because John should look like John's father. As a matter of fact, the astonishment should come the other way. The child is but a continuation of the life of the parents. The cells from which the child develops have within them the power to grow and to produce individuals like the parents. This is wonderful, but it is only another form of the wonder of a willow twig growing into a willow tree when placed in moist earth.

[Sidenote: Why the child is not identical with parents]

To the scientist, then, the wonder comes, not in the fact that the child resembles the parent, but in the fact that the child is not identical with the parent. Part of the explanation of this lack of identity, or, as it is known to science, variation, is due to the fact of sexual reproduction; that is, to the fact that the child has two parents instead of one.

[Sidenote: Microscopic study of reproductive cells]

The physiological process which takes place in the union of two reproductive cells is truly most wonderful. Of late years this has been studied under powerful microscopes and has resulted in some very wonderful revelations of the mysteries of Nature.

[Sidenote: Chromosoms in different species]

The nucleus (center of growth) of the parent cells contains little thread-like structures known as chromosoms. These chromosoms are considered to be the physical basis of heredity. In each species of animal there is a definite and a different number.

[Sidenote: Action of the chromosom]

When the sperm-cell unites with the female or germ-cell, these thread-like chromosoms pair off and unite each chromosom with the corresponding structure from the other cell. The combined structures then divide, and half of each chromosom is cast out of the cell-nucleus, and plays no part in the life of the future being; the other half is retained and divides as each new cell is formed.

Thus we see that every part of the new individual is the result of the fusion or combination of the two parents. This explains the variation of inheritance, and through this source must be traced all traits of heredity. After the original fusion of these microscopic physical elements of heredity, the future development of the individual is wholly a matter of environment and nutrition.

WHAT HEREDITY IS

[Sidenote: General characteristics due to heredity]

What heredity is and what it is not will now be considered in a practical way. It is clearly a matter of heredity that a man is born a man and not a monkey. Likewise, it is clearly a matter of heredity that distinguishes the various races of men. We could go farther and trace out and describe many of the physical distinctions which mark families, and even individuals, such as general size of frame, form of countenance, color of hair and eyes, etc.

[Sidenote: Characteristics not attributed to heredity]

Among mental traits we can safely ascribe to heredity only general distinctions. Intellectual parents are more likely to give birth to intellectual children than are parents whose natural mental faculties are less developed. There is also no doubt that certain natural characteristics of mind, such as quick temper, musical ability, etc., may be inherited. The belief, however, in the inheritance of many less distinct features, both physical and mental, is not well established by scientific investigation. Strength of muscle, control of the nervous system, susceptibility to, or freedom from dis-ease, etc., are more matters of nutrition and environment than of inheritance. The idea that consumption, alcoholism, etc., are inherited, or that the education or training of parents along certain lines will result in children with faculties adapted to similar education, is not in accordance with scientific knowledge.

SUMMARY OF FACTS REGARDING SEX AND HEREDITY

1 The function of sex has been developed in the process of evolution
for the purpose of perpetuating life.

2 The sexual functions are very closely related to the life of the
individual, and can be normal only when the laws of nutrition and of
general hygiene are observed.

3 The idea of prenatal culture as commonly taught is a delusion; the
only method that the mother can employ to control the growth of her
unborn child is to live a wholesome, normal life, physically and
mentally, and thus supply her own body and that of the child with
perfect material for the building of living cells.

4 The powers of heredity are often overestimated, and many of the
weaknesses and disorders of life supposed to be inherent can be
overcome by proper nutrition and environment. All life, whatever be
the inherited tendencies, will be developed to the highest possible
capacity by obeying the laws of individual growth, for in the
individual, as in the race, Nature is always striving to bring the
products of her work to the highest degrees of perfection.

LESSON XXI

REST AND SLEEP

REST

[Sidenote: Opposing forces in nature]

Throughout all nature we observe the phenomena of universal rhythm, manifested in opposing forces, such as heat and cold, light and darkness, construction and destruction, etc. The human body is as much affected by this rhythm as is any other form of life.

[Sidenote: Opposing forces in human system]

There are two forces continually at work within us, one toward destruction and disintegration, and the other toward construction and upbuilding. The common physiological terms for these activities are "waste" and "repair," and we observe them as one of the distinct manifestations of the universal laws of growth, progress, and evolution.

History moves in cycles. Even the life of nations depends somewhat upon this same principle of the interplay of the positive and negative forces of life.

[Sidenote: Life and death in changes of seasons]

We see the same thing in the changes of the seasons upon the face of the earth. Throughout autumn and winter there is a process of decay, death, and disintegration; leaves fall; plants and vegetables die; fruits ripen, fall and decay. This process continues until former beautiful and symmetrical bodies of matter are thoroughly disintegrated, and the particles once composing them are separated into their original elements, to be appropriated in new manifestations of life in springtime and summer.

[Sidenote: Human body compared to a machine]

We are inclined to think of the human body as a machine--a marvelous, intricate, and complex mechanism which serves our will and our desires; as a tool with which we work out our earthly destiny. But unlike man-made machines, it is self-repairing, self-adjusting, and contains within itself the forces of construction, which are constantly tending toward perfection, while our industrial machines are constantly tending toward their own disintegration and destruction.
