"The inimical
forces, partly psychical, to which our terrestrial existence is
exposed, which are termed morbific noxious agents, do not possess
the power of morbidly deranging the health of man unconditionally;
but we are made ill by them only when our organism is sufficiently
disposed and susceptible to the attack of the morbific cause that
may be present, and to be altered in its health, deranged and made
to undergo abnormal sensations and functions ‑ hence they
do not produce disease in everyone nor at all times."
Aphorism 31
If illnesses were merely a question of bacteria and viruses
invading the human organism and conquering it, then everyone who
is exposed to that contagion would inevitably succumb. There are
countless people in the world who are constantly exposed to morbific
agents who do not succumb. We all know that the air we breathe
contains a profusion of potentially harmful organisms, but we are
not struck down by each and every one of them.
It is frequently observed that only one member of a family
escapes a virulent influenza virus (or perhaps only one member DOESN'T
develop the symptoms!). Why then are some people sometimes open
or susceptible to these influences whilst others are not?
Certain diseases, whether acute or chronic, affect certain people
at certain times in their lives. "I'm prone to colds"
or "If I'm upset my stomach always feels it first" are
common cries. Our 'normal' reaction is just to say that that person
is susceptible to 'this or that' and to generally leave it there.
However, as homeopaths, it is necessary for us to begin to consider
this question of susceptibility of an organism to disease, and the
predisposition of individuals, families and races to certain diseases.
The various recurrent symptoms people experience throughout their
lives (chronic diseases) arise from individual susceptibility, from
enduring 'constitutional' weakness. Likewise, in order to determine
the 'cause' of an infectious (acute) disease, it is necessary to
take into account both the virulence of the infectious agent and
the resistance offered by the patient's defense mechanism. The resistance
to contagion is based upon the susceptibility or 'host resistance'
of the organism; it is largely determined by the miasmatic inheritance
of the individual.
For a flow chart explaining the relationship of preformative
and existing causes to susceptibility or predisposition to disease,
refer to figure 7.4 below.
The
Susceptibility of Plants and Animals
Plants and animals are susceptible to their environment, as,
of course, is the human organism. Certain plants require certain
kinds of soil in order to thrive. They also need certain kinds of
climatic and atmospheric conditions. You wouldn't see a banana
tree growing at the North Pole, for example! Plants will attempt
to adapt to changing environment but some adaptation is too extreme.
Animals also adapt to their habitat in order to survive and
in so doing they develop a protective immunity.
"Animals from certain
parts of the earth's surface develop peculiarities of their own
which are entirely different from their close relatives elsewhere.
They can withstand certain influences and hold their own under adverse
conditions which would be fatal to another of the same species developed
under differing circumstances. In other words they develop a protective
immunity against their environmental conditions.
The polar bear is immune to
the rigors of the Arctic, but is susceptible and soon succumbs to
the influence of warm climates. The Bengal tiger thrives in the
humidity of the Indian jungles: other members of the tiger family
have adapted themselves to the latitude and rarefied atmosphere
of the slopes of the Himalayas and searching winds of those heights;
either is susceptible to the ravages incident to a change in temperature."
H.A. Roberts M.D.
The human organism may react to influences in its environment,
on a mental, emotional or physical level.
If a person is not assimilating salt within his body, or if
he is, in fact, healthy but sweating profusely in a very hot climate
to which he is not accustomed, he may well develop a craving for
salt, as his body is crying out for that need (or lack) to be met.
Some people thrive on pressure and react well in a situation
of continual stress, e.g. the business tycoon who does not have
ulcers or heart pathology! In him there is a need for excitement,
and he is exhilarated by the thrill and uncertainty of his profession
rather than daunted by it. Some of us can play three sets of tennis
in the scorching heat, whilst others of us wilt in the shade on
a warm summer day.
It has been noted that some people have such a strong constitution
that they can smoke 60 cigarettes a day, drink half a bottle of
whisky, burn the candle at both ends and still live to be ninety!
H.A. Roberts wrote "Everything
that has life is more or less influenced by circumstances and environment."
Disease or disharmony results when the organism
cannot readily adapt to morbific agents (viruses, environmental
pollution, grief, jealousy, etc.) and where that organism, because
of constitutional weakness, is open or susceptible to adverse effects
from the external influences.
We have learned that as dynamic organisms we are affected
initially on a dynamic level, and this original disturbance eventually
results in the production of symptoms on the mental, emotional or
physical levels of the organism.
"The one who is made
sick is susceptible to the disease cause in accordance with the
plane he is in and the degree of attenuation that happens to be
present at the time of the contagion. The degree of the disease
cause fits his susceptibility at the moment he is made sick."
‑ J. T. Kent
It could be said that any living organism, including bacteria
and viruses, has a dynamic energy or quality, a level of vibration
or frequency which so far cannot be measured by scientific instruments.
When this frequency is within the range or frequency of any given
human organism (and therefore compliments it) it is able to produce
an effect on the dynamic level of the organism. In health, no symptoms
of any consequence will be produced.
H.A. Roberts describes it as a vacuum in the individual which
attracts and pulls to it things which are most needed that are on
the same plane of vibration as the want (or deficit) in the organism.
(If the body is deficient in a substance it will crave that substance
in order to fill the need.) He says that "in analysing
susceptibility we find it is very largely an expression of a vacuum
in the individual. The vacuum attracts and pulls for the things
most needed, that are in the same plane of vibration as the want
in the body ... the vibrations of the sick individual call aloud
for something to meet the need." In this state of lowered
resistance the body attracts that which may fulfil an inner need.
Let us illustrate the point by considering the emotional needs
of children. For example:
A child presents with dreadful behavioural problems. His behaviour
is so bad that his parents must keep close watch on him in order
to prevent his outbursts of anger and destruction, but as busy professional
people they find it hard to do this.
It is not hard to see in some cases that some children do
not receive the love and attention they need and crave , and so
some way is masterfully found by the inner being to fill the need
(the lack). It is not uncommon for attention‑seeking behaviour to develop in such cases
as a means , at least, of getting some attention. Any attention
is better than none, and so an attempt is made to satisfy the emotional
need in the best way possible in the given circumstances. This is
merely a generalisation and is used simply to illustrate a point.
Once the vacuum has been filled, the need is met and the system
is satisfied. This can be well illustrated by using the example
of childhood contagious diseases.
In childhood, before contagion, the state of health in constitutional
terms displays a need or lack. This need may be because of the child's
inherited tendencies to disease.
Roberts says that:
"The human economy has
inherited many tendencies from the accumulations of its ancestral
heritage. These tendencies show themselves in childhood in the great
number of so‑called children's diseases, which are nothing
more or less than an inward turmoil of bringing to the surface and
expelling certain conditions; again, these eruptions are a lack
of ability on the part of the patient to create a similar state
within his own economy to satisfy the susceptibility ... Nature
steps in with the laws of susceptibility and an influence is attracted
which blooms forth as an infectious or contagious disease, so as
to most fully satisfy this susceptibility."
Kent describes the meeting of a constitutional need as "stemming the influx". He
says:
"Now at the beginning
of disease, i.e. in the stage of contagion, there is a limit to
influx, for if man continued to receive the cause of disease (if
there were no limits to its influx) he would receive enough to kill
him, for it would run a continuous course until death. But when
susceptibility is satisfied, there is a cessation of cause and when
cause ceases to flow into ultimates, not only do the ultimates cease
but cause itself has already ceased."
An individual can be merely indisposed by the effects of business
failure, unrequited love, stress, overeating, poisoning, etc., but
as soon as the maintaining cause is removed the individual returns
to health. A maintaining cause will lead to indisposition; prolonged
indisposition will require treatment, and symptoms will reveal themselves
according to the idiosyncrasies of the individual patient.
Some people can lead an orderly existence, eat good wholesome
food, have no obvious maintaining causes, yet display symptoms that
express a serious inner disorder. We must now consider the element
of constitutional weakness with regard to susceptibility. The human
economy does not start afresh at the time of conception; it is
the product of imperfect parents, each with his and her own susceptibility
and maintaining causes.
Not only the physical impediments of the parents, but also
their mental dispositions at the time of conception, their diets,
whether they are under the influence of alcohol, drugs or suppressive
medication, etc., are all possible ways in which an invisible weakness
can be cultivated in the economy of the foetus. So, even at that
early stage, it is only able to make imperfect, ineffectual resistance
to some morbific influences. In other words, for those reasons
alone, it may not be a potentially healthy human being, with the
ability to adapt to its environment effectively.
Furthermore, some weaknesses may be transmitted from previous
generations. Hahnemann called these transmitted weaknesses MIASMS,
which means a taint or pollution ‑ an inherited tendency to the deviation
of flow of the vital force from its normal state. (Miasms will
be considered in detail in Unit 8)
Whole families can be susceptible to certain diseases. Our
ancestors are connected to us like links in a chain, the first being
connected to the last by the intermediary connecting links.
The tendencies towards cancer, tuberculosis, epilepsy, heart disease,
arthritis, schizophrenia, etc., are frequently seen to span the
generations of a family. Ambition, the desire for power, for excitement
or adventure, can also often follow this course (although the polar
opposite may present instead, and the business tycoon may have a
'drop out' son or daughter.)
Racial Susceptibility
Racial groups can be susceptible to particular diseases and
have immunity to others. Roberts says "It is because the similar
condition has remained unsupplied through generations and the laws
of attraction and susceptibility are manifesting their powers."
When eventually satisfied, immunity will be established which will
produce changes in the economy that bar out any more influx.
Inherited constitutional weakness will render the individual
susceptible to a deviation in flow of his vital energy, which is
then open to the possible attraction of morbific agents, as there
is not the vital power with which to resist them.
Maintaining causes will further debilitate the organism's
dynamic energy, increasing its susceptibility and lowering the resistance
to attack. This in itself weakens the organism's ability to adapt
to its ever‑changing
environment.
We are all susceptible to external and internal influences
and have suffered suppression of one kind or another. A health‑inducing
therapy would strive to lower the patient's level of susceptibility
to any given morbific agent, rather than to merely try and remove
the symptoms that might appear as the result of the original constitutional
weakness, thereby rendering the patient susceptible to the maintaining
factor.
Morbific agents do not produce symptoms in all people at all
times, but it is quite a different case with artificial morbific
agents, i.e. orthodox medicines.
"Every real medicine, namely, acts
at all times, under all circumstances, on every living human being,
and produces in him its peculiar symptoms (distinctly perceptible,
if the dose be large enough) so that evidently every human organism
is liable to be affected, and, as it were, inoculated with the medicinal
disease at all times, and absolutely (unconditionally), which, as
before said, is by no means the case with the natural diseases."
‑ Aphorism

Furthermore, it must be remembered that the greatest susceptibility
to influence is to the simillimum!
