CHAPTER X

THE REACTION OF THE PHYSICAL

As we have stated in our Foreword, there is a constant action and

reaction between the Mental States and the Physical Conditions. In this

book, from the nature of our subject, we have started with the phase

of the Mental State and worked from that point to the consideration of

the Physical Condition. In the same way, many physiologists start from

the phase of the Physical Condition, and work up to the Mental State.

But, starting from either phase, the candid investigator must admit

that there is an endless chain of action and reaction between Mind and

Body--between Body and Mind.

This action and reaction works along the lines of building-up as

well as tearing-down. For instance, if a person's Mental States are

positive, optimistic, cheerful and uplifting, the body will respond and

the Physical Conditions will improve. The Physical Conditions, thus

improving, will react upon the Mental States giving them a clearness

and strength greater than previously manifested. The improved Mental

State again acts upon the Physical Conditions, improving the latter

still further. And so on, an endless chain of cause and effect, each

effect becoming a cause for a subsequent effect, and each cause arising

from a preceding effect. Likewise, a depressed, harmful Mental State

will act upon the Physical Conditions, which in turn will react upon

the Mental States, and so on, in an endless chain of destructive

cause and effect. It is a striking illustration of the old Biblical

statement: "To him who hath shall be given; to him who hath not shall

be taken away even that which he hath." In improving either the Mental

State or the Physical Condition, one gives an uplift to the whole

process of action and reaction; while, whatever adversely affects

either Mental State or Physical Condition, starts into operation a

depressing and destructive process of action and reaction. The ideal

to be aimed at is, of course, "A healthy Mind in a healthy Body"--and

the two are so closely related that what affects one, favorably or

unfavorably, is sure to react upon the other.

Just as the influence of the Mental States over the Physical Conditions

has been shown to operate by means of the Sympathetic Nervous System

(controlled of course by the Subconscious Mind), so the influence

of Physical Conditions over Mental States may be explained in

physiological terms. In order to understand the reaction of the Body

upon the Mind, we have but to recall the fact that the Subconscious

Mind is the builder and preserver of the very brain-cells which are

used by the Conscious Mind in manifesting thought. And also, that the

entire Nervous System, both Cerebro-Spinal as well as Sympathetic, is

really under the control of the Subconscious Mind so far as growth

and nourishment is concerned. The very brain and nerve-centers in and

through which is manifested thought, feeling, emotion, and will, are

nourished by the Sympathetic System, and are hurt by anything affecting

the latter. The Sympathetic System joins all parts of the organism

so closely together that trouble in one part is reflected in other

parts. Just as depressing thoughts will cause the organs to function

improperly, so will the improper functioning of an organ tend to

produce depressing thoughts.

Herbert A. Parkyn, M. D., well states the action and reaction of Mind

and Body, as follows: "A tree is much like a human being. Give it

plenty of fresh air, water and a rich soil, and it will flourish. In

the same degree in which it is deprived of these does it wilt, and _the

first part of the tree to wilt when the nutrition becomes imperfect

is the top_. This is owing to the force of gravity; the blood of the

tree, the sap, having to overcome this force of nature when nourishing

the highest leaves. The blood of man is also affected by this same

force, and the moment a man's circulation begins to run down, owing to

stinted nutrition, we find that the first symptoms of trouble appear

in the head.... The brain failing to receive its accustomed amount of

blood, such troubles as impaired memory, inability to concentrate the

attention, sleeplessness, nervousness, irritableness, the blues and

slight headaches develop; and the impulses sent all over the body

becoming feebler, the various organs do not perform their functions

as satisfactorily as usual. The impulses to the stomach and bowels

becoming weaker and weaker, dyspepsia, or constipation, or both, soon

follow. As soon as these, the main organs of nutrition, are out of

order, nutrition fails rapidly and more 'head symptoms' develop. Every

impulse of the muscular system leaves the brain, and the strength

of these impulses depends upon the nutrition to the brain centers

controlling the various groups. As the nutrition to these centers

declines, the whole muscular system, including the muscles of the

bowels, becomes weaker and the patient complains that he exhausts

easily. The impulses for elimination becoming weaker, waste products

remain in the circulation, and any of the evils, which naturally follow

this state of affairs, such as rheumatism, sick-headache, biliousness,

etc., are likely to develop. The centers of the special senses feeling

the lessening of the vital fluid, such troubles as impaired vision,

impaired hearing, loss of appetite (sense of taste) and inability to

detect odors quickly soon follow. The sense of touch becomes more

acute, and it is for this reason that one in poor health becomes

hypersensitive. Lowered circulation in the mucous membrane of the

throat and nose is often the cause of nasal catarrh appearing on the

scene as an early symptom."

It will thus be seen that the Physical Conditions, perhaps originally

caused by depressing Mental States, have brought about a state

of affairs in which the brain is imperfectly nourished and which

consequently cannot think properly. The liver being out of order, the

spirits are depressed; the brain being imperfectly nourished, the

attention and will are weakened, and the patient finds it hard to use

his mind to influence his bodily conditions. The bowels not moving

properly, the waste-products poison the circulation, and the brain is

unable to think clearly. In fact, the whole physical system is often so

disturbed that a condition known as "nervous prostration" sets in, in

which it is practically impossible for the patient to hold the Mental

States which will improve the Physical Conditions. In these cases

outside help is generally necessary, unless in cases where a sudden

shock, or an urgent necessity arouses the latent mental forces of the

individual, and he asserts the power that is in him, and begins to

reverse the chain of cause and effect and to start on the upward climb.

The following additional quotation from Dr. Parkyn, gives us a vivid

insight into the effect upon the Mental States of abnormal Physical

Conditions: Dr. Parkyn says: "No organ of the body can perform

its functions properly when the amount of blood supplied to it is

insufficient, and we find, when the blood supply to the brain is not

up to the normal standard, that brain functions are interfered with

to a degree corresponding to the reduction in the circulation. Since

the amount of blood normally supplied to the brain is lessened in

nervous prostration, we find that the memory fails and the ability

to concentrate the attention disappears. The reasoning power becomes

weakened and the steadiest mind commences to vacillate. Fears and

hallucinations of every description may fill the mind of a patient

at this stage, and every impression he receives is likely to be

greatly distorted or misconstrued. Melancholia with a constant fear of

impending danger is often present. In fact, the brain seems to lose

even the power to control its functions, and the mind becomes active

day and night.... The reduction of the nutrition to the brain lessens

the activity of all the cerebral centers also, and digestion becomes

markedly impaired, thereby weakening the organ itself upon which the

supply of vital force depends."

The physiologist is able to furnish a great variety of illustrations

of the effect of Physical Conditions over Mental States. He shows

that many cases of mental trouble are due to eye-strain, and other

muscular disturbances, and that serious mental complaints sometimes

arise by reason of physical lesions. The very terms used to designate

certain abnormal mental states show the relation, as for instance,

_melancholia_ which is derived from the Greek words meaning "black

bile"; and _hysteria_, which is derived from the Greek word meaning

"the womb; or uterus." Every one knows the Mental States produced by

a sluggish liver, or by dyspepsia, or from constipation. We all know

the difference between our mental capacity for thinking when we are

tired, as contrasted with that accompanying the refreshed physical

condition. No man, whatever his philosophy, can truthfully claim to be

able to maintain a placid, even disposition, and a perfectly controlled

temper, when he is suffering from a boil on the back of his neck. And,

all know that after indulging in the midnight "Welsh rarebit," one is

apt to dream of his grandmother's ghost, or see dream elephants with

wings. All know the delirium produced by overindulgence in liquor, and

the hallucinations that accompany fever. The effect of drugs, tobacco,

and alcohol upon the Mental States are well known. "Philip drunk" is

a very different mentality from "Philip sober." The Mental States

accompanying particular diseases are well known to physicians. One

disease predisposes the sufferer to gloominess, while another will

induce a state of feverish hilarity. Some leading authorities now hold

that many cases of insanity are really due to abnormal conditions of

the blood, rather than to any diseased condition of the brain.

One of the most marked instances of the action and reaction of Mental

States and Physical Conditions is met with in the activities of

the sexual organism. Psychologists very properly hold that sexual

excesses and abnormalities are largely due to improper thinking, that

is, by allowing the attention and interest to dwell too strongly and

continuously upon subjects connected with the activities of that part

of the physical system. Mental treatment along the lines of Suggestive

Therapeutics has resulted in curing many persons of troubles of this

sort. But, note the correlated fact--excess and abnormalities of the

kind mentioned, almost invariably react upon the mentality of the

person indulging in them, and softening of the brain, paralysis, or

imbecility have often arisen directly from these physical abuses. It

will be seen that any sane treatment of these troubles must take into

consideration both Body and Mind. In the same way it is a fact that

just as certain Mental States, notably those of fear, worry, grief,

jealousy, etc., will injuriously affect the organs of digestion and

assimilation, so will imperfect functioning of these organs tend to

produce depressing mental states similar to those just mentioned. Many

instances of the strange correspondences are met with in the study of

physiological-psychology, or psychological-physiology.

In order to more fully appreciate the relation between the Body and the

Mind, let us read the following lines from Prof. Halleck: "Marvelous

as are the mind's achievements, we must note that it is as completely

dependent upon the nervous system as is a plant upon sun, rain and

air. Suppose a child of intelligent parents were ushered into the

world without a nerve leading from his otherwise perfect brain to any

portion of his body, with no optic nerve to transmit the glorious

sensations from the eye, no auditory nerve to conduct the vibrations of

the mother's voice, no tactile nerves to convey the touch of a hand,

no olfactory nerve to rouse the brain with the delicate aroma from

the orchards and the wild flowers in spring, no gustatory, thermal or

muscular nerves. Could such a child live, as the years rolled on, the

books of Shakespeare and of Milton would be opened in vain before the

child's eyes. The wisest men might talk to him with utmost eloquence,

all to no purpose. Nature could not whisper one of her inspiring truths

into his deaf ear, could not light up that dark mind with a picture

of the rainbow or of a human face. No matter how perfect might be the

child's brain and his inherited capacity for mental activities, his

faculties would remain for this life shrouded in Egyptian darkness.

Perception could give memory nothing to retain, and thought could not

weave her matchless fabrics without materials."

The very feelings or emotions themselves are so closely related

to the accompanying physical expressions, that it is difficult to

distinguish between cause and effect, or indeed to state positively

which really is the cause of the other. Prof. William James, in some

of his works, strongly indicates this close relation, as for instance

when he says: "The feeling, in the coarser emotions, result from the

bodily expression.... My theory is that the bodily changes follow

directly the perception of the exciting fact, and that our feeling

of the same changes as they occur _is_ the emotion.... Particular

perceptions certainly do produce widespread bodily effects by a

sort of immediate physical influence, antecedent to the arousal of

an emotion or emotional idea.... Every one of the bodily changes,

whatsoever it may be, is _felt_, acutely or obscurely, the moment it

occurs.... If we fancy some strong emotion, and then try to abstract

from our consciousness of it all the feelings of its bodily symptoms,

we have nothing left behind.... A disembodied human emotion is a sheer

nonentity. I do not say that it is a contradiction in the nature

of things, or that pure spirits are necessarily condemned to cold

intellectual lives; but I say that for _us_ emotion disassociated from

all bodily feelings is inconceivable. The more closely I scrutinize my

states, the more persuaded I become that whatever 'coarse' affections

and passions I have are in very truth constituted by, and made up of,

those bodily changes which we ordinarily call their expression or

consequence.... But our emotions must always be _inwardly_ what they

are, whatever may be the physiological ground of their apparition.

If they are deep, pure, worthy, spiritual facts on any conceivable

theory of their physiological source, they remain no less deep, more

spiritual, and worthy of regard on this present sensational theory."

A deeper consideration of the relation between Mind and Body would

necessitate our invading the field of metaphysical speculation, which

we have expressed our intention to avoid doing. Enough for the purposes

of our present consideration is: _the recognition that each individual

is possessed of a mind and a material body; that these two phases or

aspects of himself are closely related by an infinite variety of ties

and filaments; that these two phases of his being act and react upon

each other constantly and continuously; that in all considerations of

the question of either mental or physical well-being, or both, that

both of these phases of being must be considered; that any system of

therapeutics which ignores either of these phases, is necessarily

"one-sided" and incomplete; and that, while, for convenience and

clearness of specialized thinking, we may consider the Mind and the

Body as separate and independent of each other, yet, we must, in the

end, recognize their interdependence, mutual relation, action and

reaction._

Thus, the New Psychology recognizes the importance of the Body, while

the New Physiology recognizes the importance of the Mind. And, in the

end, we feel that both physiology and psychology must be recognized as

being but two different phases of one great science--the Science of Life.
