1. Exact Observation: The word ‘Exact’ indicates: ‘Accurate
or correct in all details.’ Another meaning of this word is:
‘Tending to be accurate and careful about minor details’. The
word Observation indicates: ‘The action or process of closely
observing or monitoring.’ In short this method suggests
monitoring minor details.
2. Correct interpretation of observed facts: There are
three important words in this and their dictionary meanings are:
a. Correct: Free from error.
b. Interpretation: [Interpret]: Explain the meaning of. Perform
in a way that conveys one understands of creator’s idea.
c. Facts: A thing that is indisputably the case. Information
used as evidence or as part of report.
In short what ever the information collected should be
interpretated in such a way that such information should be free
from error. The purpose of this is to understand them in
relation to each other and their causes.
3. Rational explanation of facts: There are two important words
in this and their dictionary meanings are:
a. Rational: Based on or in accordance with reason or logic.
Able to think sensibly or logically. Endowed with the capacity
to reason.
b. Explanation: [Explain]: Make clear by describing it in more
detail. Excuse or justify one’s motives or conduct.
In short whatever facts we have should be describe in detail on
the basis of logic.
4. Scientific Construction: Here the word Construction
indicates: The action or process of construction. The original
word is to construct which means to build or erect or form from
various conceptual elements.
In short we have to represent the facts on the basis of science
in such a way that it looks as reality.
According to F and W dictionary the search for the cause
of anything may proceed according to any one of four methods:
1. The method of agreement in which a condition uniformly
present is assumed to be probably a cause.
2. The method of difference in which the happening of an event
when a condition is present and its failure when a condition is
absent, lead to the assumption of that condition as a cause.
3. The method of concomitant variations, in which the
simultaneous variation in similar degree of condition and event
establishes a causal relation.
4. The method of residues or of residual variations, where after
subtracting from a phenomenon the part due to cause already
established the remainder is held to be due to some other
unascertained cause or to the known remaining causes.
f. Basic Characteristics of Inductive Logic: The way of
argument of this logic is rested on principles a posteria. This
indicates that in this method principles are derived from our
uncontradicated experience. In other words we can say that we
accept it without contradiction. On the base of these arguments
we never yields a necessary truth. This does not indicate that
Inductive Logic is only a wild speculation. But in this method
of logic conclusion does not necessarily follow from it
premises. This condition is seen in deductive method of logic.
Here conclusion is based on a certain degree of probability.
Greater the reliability of premises higher the probability of
the truth of conclusion.
Here particular conclusion is drawn from particular to general.
For example: Tom, Hick, Harry have yellow eyes. They have
Jaundice. Therefore those who all have yellow eyes have
Jaundice. Here it is noticeable that the transition here is from
the part to the whole from the particular to universal from some
particular truth we leap to generalized truth.
By inductive reasoning we ascertain what is true of many
different things. Our senses tell us what happens around us and
by proper reasoning we may discover the laws of nature, in
consequence of which they happen.
Every mind conceives intuitively some ideas or judgments which
are at once primary and certain otherwise we could have no
foundation for inference and to infer one idea or judgment from
others would give no certainty. These ideas are called first
truths. They are given by the senses, the consciousness and the
reason and they are innumerable. For example: “I exist. There is
an external world. This body is solid, extended, round, red,
warm or cold are first truths.” At first these ideas are
particular but afterward the mind unites those which are similar
or which agree in some respect in to classes. This is called
“Generalization”. To express this we no longer say this or that
body but body, not coat, shirt, trousers, but clothes only.
2. Deductive Logic:
a. Introduction: The deductive method in science is the
application of the principles of deductive logic to scientific
research.
b. Dictionary Meaning: The word has originated from the word
deduce that means to
1. Trace the course or derivation of.
2. To infer by logical reasoning.
3. Conclude from known facts or general principles.
The dictionary meaning of the word deduction suggests:
1. A deducting or being deducted; subtraction
2 A sum or amount deducted or allowed to be deducted.
c. Definition: “Deductive method in logic is the scientific
method that proceeds by deduction.”
d. Basic Characteristics of Deductive Logic: This method
of logic works on certain basic priority principles. This method
finally reach to such truths that are justified by pure thoughts
or reasoning. The theme of this method is: In a valid argument
if premises are true than conclusion from these premises must
necessarily be true also. In this method conclusion of a
deductive argument never goes beyond what the premises state. In
this method conclusion is drawn from general to particular. This
can be beautifully understood by example:
1. All doctors are wise. [General]
2. Kent is a doctor. [Particular]
Therefore Kent is also wise. [General To Particular.]
This is a syllogistic argument. It is a process of reasoning
from out of two statements having common part. On the basis of
this third statement is given. In above-mentioned example
‘Doctor’ is a common part, which is there in both the statements
on the basis of this third statement, is given.
In deductive reasoning we do the opposite and infer what will
happen in consequence of the laws.
As induction is the antonym of deduction. This is a belief of a
common man. But this is an error. They are simply opposite ways
of arriving at the same conclusions, two modes of using the same
general process, namely: inference or inferring. Reasoning a
priori and a posteriori are not different modes of reasoning but
arguments differing in the character of one of the premises. It
is merely a difference of viewpoint. In one we reason from
antecedents, in other from consequents. [Antecedents: any
happening or thing prior to another.] [Consequents: following as
a result; resulting.]
4. Concept of John Stuart Mill [1806-1873]: J.S.Mill is
considered to be a great philosopher. His philosophy is called
utilitarianism i.e.
a. Man looks for pleasure. [Basic tendency]
b. All activities to avoid pain and gain pleasure.
c. Present is most important. So live well and die well.
Dr. Hahnemann was not aware of Mill’s philosophy when he framed
homoeopathy but he used his principle earlier than Mill.
In short Mill’s theory suggest [Theory of Induction i.e.
Principal of association]:
1. No generalization.
2. Only association between particular events is sufficient.
3. Similarity is the basis of association.
4. Particular to Particular. This similar pattern is called
generalization. It is not a general principle; it is a pattern
recurring in particular events.
Logic and Homoeopathy: Analysis of Organon of Medicine as well
as the history of emergence of Homoeopathy shows clearly that
Homoeopathy is a product of Inductive logic applied to the
subject of medicine. In fact it is one of the most and first
brilliant examples of the application of inductive method to the
solution of one greatest problem of humanity, namely treatment
and cure of disease. This is the chief contribution to the
science by Dr. Hahnemann. He was first to make a comprehensive
induction of medical facts and deduce the general law of
therapeutic medication upon a sound basis. Now we will try to
understand the application of Logic to basic principles of
Homoeopathy.
a. Emergence of Homoeopathy and Law of Similar: Hahnemann
was not the first clinician to note that drugs selected on the
basis of their similarity to the disease, can cure the similar
disease condition. He cites previous experiences of clinicians
like Hippocrates, parcelus and Stahl in whose writings he found
the most definite statement of the Law of Similar. But none of
these proceeded systematically to offer an experimental proof.
He also cites instances in which naturally occurring similar
disease tend to repel each other as in the celebrated instances
of Cow-pox and Small-pox which guided jenner towards vaccination
as a method of protection against small-pox. While translating
Cullen’s materia Medica from English in to German, he took
exception to the explanation Cullen advanced for the undoubted
efficacy of Cinchona bark in the treatment of ague. He thought
that Cinchona helped cases of ague on account of its capacity to
produce a similar state. He proceeded to dose himself with
Cinchona and recorded in detail his experiences in the form of
symptoms. He found to his great surprise that the troubles he
went through resembled closely a mild attack of ague. This
convinces him that he was following right path. Gradually he
started to prove various drugs on himself, family members and
others. In short through the method of proving he tried to apply
this principle for all. [Particular to General----Inductive
Logic] on the basis of such rich experience of years finally he
came to the conclusion that a drug capable of producing in a
healthy person a diseased state exactly similar to that observe
in a diseased person, acts as a curative agent if the disease is
in a curable stage. This was nothing but the systematic
establishment of the law of similar based on Deductive logic.
[On the basis of General information to Particular
conclusion---- Deductive logic] Up to the year 1810 Dr.
Hahnemann used the word Similia Similibus only. There is not a
single evidence of using the word ‘Curenter’ or’Curanter’ before
1810. Later on he used the word ‘Curenter’.
b. Holistic Concept of Homoeopathy: Homoeopathy is based on
holistic concept.
The dictionary meaning of the word ‘Holistic’ suggest:
“concerned with, or dealing
with wholes or integrated systems rather than with their parts.”
Again the word ‘Integrate’ suggest; “ make in to a whole”. And
further the word ‘whole’ suggest:
“ All of something including all its component elements or
parts.” Or “An assemblage of parts that is regarded as single
only.” This is the area where Homoeopathy differs from Modern
Medicine. They believe that whenever a person is diseased his
particular system or an organ or a particular part of the body
is diseased and remaining other portion of body becomes free
from disease. At this place homoeopathy believes that there is a
spirit like dynamic power [Vital force] that animates the human
organism and gives the life to it. Whenever such dynamic force
is deranged it affects the person as a whole. As a result of
this internal derangement a person become a patient and he
express this derangement in the form of different out word
manifestations, which include mental, emotional, intellectual as
well as physiological and pathological manifestations. When we
integrate all these data it clearly represent the person as a
whole. So this Holistic concept indicates application of the
method of Inductive Logic.
[Particular to General---- Inductive Logic.]
c. Concept of Generalization: Generalization is the process
of identification and applies forming general notions or
formation of general concepts or conceptualization of facts from
particulars by the process of mental abstraction. Generalization
becomes valid when it follows deductive and inductive method of
logic. It becomes invalid when these methods are not
co-ordinated and conclusions drawn are wide than data and does
correspond reality.
Definition: Generalization is an act or process of arriving at
generals out of particulars.
Capacity of mind to take in objects in wholes, to store these
images in memory in complete form and to revive these original
images when necessary for evaluation in comparison to new
experience is the process of individualization.
Dictionary Meaning: To form general principles or conclusions
from detailed facts, experience etc.
Process: Generalization is a process, which is achieved by
proceeding from particular to general through:
a. Progressive Generalization. b. Abstraction.
This is the reverse process of individualization. This can be
beautifully understand by the process of mind which entirely
depends upon:
1. Complete, accurate and unprejudiced observation.
2. Recording of observations with regards to its description,
character, number etc. A mind is trained to classify the facts
comprising the database and to rearrange them so that
interrelationship between them becomes apparent. Facts can be
grasped and stored readily for subsequent use.
Examples:
1. Generalization at the level of Location: When a particular
symptom is found at two or more locations it becomes general. A
particular lesion at fold of palm, mouth angle or inner canthi
will be considered as skin fold.
2. Generalization at the level of Sensation and Pathology: When
a particular sensation or pathology is found at two or more
place it becomes general. Pricking at fingers, soles or palms
will consider as pricking in general.
3. Generalization at the level of Modalities: When a particular
modality is found at two or more places it becomes general. Pain
in knee joint which is aggravated by motion and pain in shoulder
joint aggravated by motion will consider as aggravation by
motion in general.
In short the process of Generalization is applied in the field
of homoeopathy for the purpose of formation of conceptual image,
which is based on basic principles of Inductive logic.
d. Concept of Individualization: The word
‘Individualization’ is derived from the Latin word ‘Invidious’.
In means not and dividuous means divisible. The individual is
unique, not further classifiable. It is what it is. It is not in
the sense that is incapable of being divided in to parts but it
cannot be so divided in its nature and remains what it is.
Definition: Individualization means identification of a
particular instance in a group of common attributes. It is the
highest expression of one’s expression.
Dictionary meaning: Different terminologies connected with
Individualization and their dictionary meanings are as under.
1. Individual: A single person especially when regard as
distinct from others.
2. Individuality: A total character peculiar to and
distinguishing an individual from others.
3. Individualize: To make individual in character.
Process: Individualization is a process, which is achieved by
proceeding from general to particular through:
a. Decrease generalization. b. Progressive differentiation.
This is the reverse process of generalization. This
technique of individualization forms an integral part of the
homoeopathic system of medicine and its concept of health,
disease and cure. Each individual has to be kept in mind in
relation to health, disease and cure because no two men are
alike in this world. The psychosomatic make up of an individual
varies widely from other. Not only has that but the successful
application of the Law of Similar depended entirely on the
concept of individualization, which forms the cornerstone of
homoeopathic practice. The concept of individualization takes in
to consideration the total response of the organism to the
unfavourable stimuli or environment. This response is seen
through signs and symptoms of an individual on three planes:
Emotional, Intellectual and Physical. The exact similarity in
the application of law of similar can be ensured only if the
patient is observed through the principle of individualization.
So on the basis of patients causation, present history, past
history, family history, etc physician has to individualize the
patient as a person and it can only possible with an exhaustive
knowledge of deductive Logic.
Examples:
1. Individualization at the level of causation: Common cold and
coryza in a cold weather is a common characteristic but if it is
in cold, damp basement that Dulcamara will be the choice of
remedy.
2. Individualization at the level of Location: For a person who
is suffering from renal calculi and especially in the left
kidney, we may think of Berberis Vulgaris out of so many drugs.
3. Individualisation at the level of Sensation: Sore, lame and
bruise feelings are characteristics sensations, which
individualize the patient of Arnica from other similar
medicines.
4. Individualization at the level of Modalities: Aggravation
between 4.00 to 8.00.pm is a characteristic, which suggests the
rug Lycopodium and individualize that patient as a person from
others.
5. Individualization at the level of Extension: Stitching pain
in chest is a feature indicating to a large number of drugs in
the Repertory and if it is extended to the liver region it
narrows down from many drugs to a single drug Calc. Phos that
individualize that patient as a person from others.
On the basis of above discussed matter it is clear that
Homoeopathy doesn’t exit without the process of
Individualization and for that the exhaustive knowledge of
Deductive logic can only help us.
e. Concept of Drug proving: In the time of Dr.Hahnemann,
knowledge of the true properties of drugs hardly existed. The
systematic knowledge of Materia medica in those days was not
there. Data from poisonings, uncritical clinical observations of
drugs applied on the basis of fanciful theories of the origin of
disease. Dr. Hahnemann was not satisfied with this method. In
such a critical situation he ascertained the true properties of
drugs by careful experimentation on healthy human beings and not
on animals. Hahnemann thus could be considered as the father of
human experimental pharmacology. He insisted that only those
drugs whose properties were carefully ascertained by experiments
on the healthy human beings and which were prepared according to
specific instructions should be employed as remedial agents for
cure. In this way all the altered sensations and functions
experienced by the provers were recorded in the words of persons
and they all were noted in the original language of patient
without adding or changing any word. Dr. Hahnemann called it as
Materia Medica Pura.
Later on Dr. Hahnemann followed an anatomical schema that is
from head to foot, in recording the positive drug effects and
under each heading he collected and put all the symptoms from as
many provers there were in each case. Then he shifted the
symptoms common to each of them from symptoms peculiar to each
of them. Finally he put under the heading [For example ‘head’]
and put all the common symptoms and peculiar symptoms noted by
idividual provers. This shows that how many varieties of head
symptoms that drug is capable of producing in various
individual.
This clearly indicates that to prove a single drug to know its
disease producing power on various healthy provers and on the
basis of this available data try to make common as well as
peculiar characteristics of that particular drug and consider
its disease producing capacity as disease curing capacity
requires the application of Inductive method of logic.
[Particular to General].
f. Concept of Causation:
History: Hippocrates taught that all diseases aroused from an
interdependent constellation of causes rather than any single,
isolated etiological factor. This constellation includes the
nature of the pathogen, the environmental conditioning factors
and the susceptibility of an individual.
Since the beginning of the nineteenth century when the European
medicine decided to become a science they had a belief that
every event must have a cause and that under similar conditions;
the same cause produces the same effect. Concept of causation of
disease is different in different schools of medicines.
So-called modern medical science believed that multiple factors
are responsible for the emergence of disease. In homoeopathy the
concept of causation is closer to multifactorial causation
theory. Broadly speaking Exciting cause, maintaining cause and
Fundamental cause are the responsible for the causation of
disease. Apart from this Vital force plays an important vital
role in the evolution of disease.
Dictionary meaning: dictionary meanings of the various
terminologies related to the word causation are as under.
1. Cause: Something that brings about an effect or a result.
2. Causal: Expressing or indicating cause.
3. Causality: The relation between and its effect.
4. Causation: The act or process of causing.
5. Causative: Expressing causation.
Definition: causation or causality is the operation of causal
energy.
Concept of modern science regarding characteristics of cause:
1. When cause appears effect follows it: This is a wrong belief
of modern medical science. This can be beautifully understood by
examples. All pathogenic bacteria are supposed to give rise to
lesions. But it is known however that this is not so, as
pathogenic bacteria may be found in so called carriers, i.e. in
people who do not present any lesion or clinical manifestations.
2. When cause disappear effect disappear: Clinical experience
teaches that the disappearance of a certain structure, function
or microorganism need not necessarily be followed by the
disappearance of the clinical syndrome that was considered to be
its effect.
3. When cause varies effect varies: variations in the number of
pathogenic bacteria are seldom accompanied by corresponding
variations in the lesion. Similarly variations in the
percentages of blood calcium are not necessarily reflected by
corresponding variations in the clinical picture.
4. Cause always precedes the effect: In so many cases it going
to happen that initially on the basis of clinical manifestations
the diagnosis of condition is done and later on the causative
factor for that condition is find. For example Tuberculosis and
Mycobacterium Tuberculin.
Types of Causes: Homoeopathy believes that there are
mainly three types of basic causes responsible for emergence of
acute as well as chronic disease conditions.
They are:
1. Exciting cause: Exciting causes are those causes, which
excites the disease conditions to occur. They are responsible
for the production of acute disorders that are rapid in their
onset, quick to reach crisis and ends in complications or
recovery. Usually exciting factors are Physical, chemical,
biological, environmental, social, cultural, economical, or
spiritual conditions or factors which activates a latent miasm
and brings forth crisis and serious complications. They are
responsible for the production of individual, epidemic and
sporadic disease conditions as well as acute exacerbation of
chronic disease conditions. [Reference apho. No. 5 and 73.] In
short what ever may be the particular diagnosed and named acute
condition these are the general responsible factors for its
emergence. [Particular to General- Role of Inductive Logic.]
2. Maintaining cause: The dictionary meaning of the word ‘
maintain’ suggest:
‘To continue’. These are those conditions, which maintain the
present disease condition. Dr. Hahnemann raises this category of
etiology in aphorism no. 7 and 77 of the Organon of medicine and
also in the chronic disease. Maintaining cause can be of several
types including those conditions which need mechanical or
surgical aid and those induced by unhealthy life style, poor
living conditions, occupation hazards, continuous telluric and
meteoric environmental stress as well psychological strain.
These also include diseases maintained by soul through spiritual
crisis, mental confusion and emotional turmoil. In the aphorism
no. 77 Dr. Hahnemann points out that maintaining cause produce
pseudo chronic diseases. If a maintaining cause continues for a
number of years it may activates a latent miasm and the
constitution will suffer from pathological states. In short all
such general maintaining causes are responsible for maintenance
of any particular disease condition or conditions. [Particular
to General- Role of Inductive Logic.]
3. Fundamental cause: Fundamental causes are the ‘Miasms’,
which have the power to disturb the tune of vital force and
causing disharmony in the constitution and temperament.
Here the layer of miasm remain dominant over the constitution
and display the symptoms of their syndromes. These fundamental
causes are responsible for the emergence of various disease
conditions and Dr. Hahnemann broadly classify them in to:
1.Psoric miasmatic disease. [Functional Disturbances]
2.Sycosis miasmatic disease. [Extra growth or formations]
3.Syphilis miasmatic disease. [Destructive changes]
When we refer to the aphorism no.80 in the organon of medicine
it clearly indicates that what so ever may the disease condition
from a simple bronchitis to cancer psora is the mother of all
the disease conditions. This concept of giving general causation
for various named and classified disease condition according to
modern medical science suggest application of the knowledge of
Inductive method of logic.
[Particular to General- Role of Inductive Logic.]
g. Role of Diagnosis in homoeopathy and its relation with logic:
Introduction:
One of the popular misconceptions about homoeopathy is that it
has little to do with diagnosis and that a homoeopathic
physician does not require the various ancillary facility like
X-ray, pathological and Bacteriological investigation, E.C.G.
etc. It is very easy for us to understand the basic
misconception behind this. The prescription in homoeopathic
practice is determined by a detailed study of the symptomatology
out side the diagnostic sphere. This gives impression to common
people that a homoeopathic physician is not primarily interested
in diagnosing his cases. It makes easy to apply the principles
of homoeopathy for those persons who do not have medical
education of homoeopathy. But actually it is not true.
Dictionary meaning: The identification of the nature of an
illness or other problem by examination of the symptoms.
Definition: Diagnosis implies the understanding and detection of
the site and nature of lesion in a particular anatomical part of
the body.
This concept of diagnosis of modern medicine presupposes two
assumptions, which are open for criticism:
1. The material part of the living organism is the sole and
fundamental reality and all other phenomena excepting the
structural changes of the body are nothing but functions or
effects of the altered of the body.
2. The body is looked upon as a machine consisting of an
assemblage of different parts and change or damage of any part
can take place independently of that of any other or rest of the
body. According to this view a disease can be cured by treating
the part particularly affected just as a machine is adjusted and
set going by repairing the particular damaged part.
But Homoeopathy treats the patient as a whole, which is more
than the sum of its parts, which is something over and above
them. Homoeopathy aims at individualization of patient and drug.
So only nosological diagnosis is not the sole aim of
homoeopathic physician but along with this diagnosis of the
patient as a person is an important diagnosis every homeopathic
physician has to do. That will only solve the fundamental
purpose of individualization. Dr. Hahnemann has nicely mentioned
this thing in his book organon of medicine in the aphorism no.
3.Acoording to him every homoeopathic physician must know what
is to be cured in disease and what is curable in medicine. This
will direct throw some light on the importance of diagnosis in
the field of Homoeopathy.
Importance of Diagnosis in Homoeopathic Practice:
1. A complete diagnosis offers a full comprehension of the
patient’s personality, his constitution and the mechanism of the
production of symptoms.
2. It gives an idea of the locations, the pathological changes,
the pathogenic agent, the physiological disturbances induced,
the psychological accompaniments, and the pathogenesis.
3. Similarly, it will not be possible to give the prognosis with
any resemblance of accuracy unless we possess this knowledge of
knowledge.
4. The knowledge of diagnostic symptoms helps in determining the
individual characteristic symptoms, which form the basis of a
prescription in homoeopathic practice according to the concept
of the totality of symptoms.
5. Diagnosis also enables the physician to choose his case and
to eliminate cases requiring, primarily, surgical or other
measures.
6. It aids prescription by giving information about the
locations and the nature of pathological changes present
[pathological Generals].
7. Diagnosis can help a homoeopathic physician to plan the
general treatment and prophylactic measures. It also makes
comparative assessment of the therapeutic results possible.
In short by the process of Diagnosis we will only try to emerge
a portrait of a person who is patient and try to individualize
him on the mental as well as on the physical level [as a whole].
This clearly indicates the predominant role of Deductive method
of logic. [General to Particular—Role of Deductive Logic]
Statistics and Logic: The English word ‘statistics’ has been
derived from the Latin word ‘Status” which means, a state. In
fact in olden days, statistics was used only to keep the records
of the income and expenditure of a state. Later on it became a
common term to denote numerical facts related to the state.
Definition: Statistics is a science of statistical method,
meaning thereby the study of the methods used in statistics
such: Collection of data, classification, and generalization of
data, interpretation and analysis of data.
Classification: Statistics ha been classified as:
1. Descriptive Statistics.
2. Inferential Statistics or Inductive Statistics.
Logic has direct relation with Inductive Statistics. Whenever
the population is too large, we try to infer about that
population on the basis of our study of a sample of that
population and that part of Statistics, which deals with such
matters, is known as inductive statistics. It deals with concept
like reliability, confidence, and probabilities etc. Regarding
Inductive Statistics Blalock says: ‘ Statistical inference as
the process is called involves much more complex reasoning than
does descriptive statistics but when properly understood and
used it becomes a very important tool in the development of
science. In short on the basis of a selected sample we have to
take judgment regarding the whole community on the basis of
statistics.
Conclusion: On the basis of above mention discussion it
is very clear that each and every basic principle upon which
Homoeopathy stands is firmly supported by Logic and this it self
prove the scientific basis of Homoeopathy.
