THE ELEMENTS OF MEMORY

Four Special Memory Processes
You have learned of the sense-perceptive and judicial processes by which
your mind acquires its knowledge of the outside world. You come now to a
study of the phenomenon of memory, the instrument by which your mind
retains and makes use of its knowledge, the agency that has power to
resurrect the buried past or power to enfold us in a Paradise of dreams
more perfect than reality.

In the broadest sense, memory is the[Pg 4] faculty of the mind by which we
(1) retain, (2) recall, (3) picture to the mind’s eye, and (4)
recognize past experiences.

Memory involves, therefore, four elements, Retention, Recall,
Imagination and Recognition.

THE MENTAL TREASURE VAULT AND ITS LOST COMBINATION

Chapter II

THE MENTAL TREASURE VAULT AND ITS LOST COMBINATION

What Everyone Thinks
Almost everyone seems to think that we retain in the mind only those
things that we can voluntarily recall; that memory, in other words, is
limited to the power of voluntary reproduction.

This is a profound error. It is an inexcusable error. The daily papers
are constantly reporting cases of the lapse and restoration of memory
that contain all the elements of underlying truth on this subject.

[Pg 8]
Causes of Forgetfulness
It is plain enough that the memory seems decidedly limited in its
scope. This is because our power of voluntary recall is decidedly
limited.

But it does not follow simply because we are without the power to
deliberately recall certain experiences that all mental trace of those
experiences is lost to us.

Those experiences that we are unable to recall are those that we
disregarded when they occurred because they possessed no special
interest for us. They are there, but no mental associations or
connections with power to awaken them have arisen in consciousness.

Things are continually happening all around us that we see with but
“half an eye.” They are in the “fringe” of[Pg 9]
Seeing with “Half an Eye”
consciousness, and we
deliberately ignore them. Many more things come to us in the form of
sense-impressions that clamorously assail our sense-organs, but no
effort of the will is needed to ignore them. We are absolutely
impervious to them and unconscious of them because by the selection of
our life interests we have closed the doors against them.

In either case, whether in the “fringe” of consciousness or entirely
outside of consciousness, these unperceived sensations will be found to
be sensory images that have no connection with the present subject of
thought. They therefore attract, and we spare them, no part of our
attention.

Just as each of our individual sense-organs
[Pg 10]
selects from the multitude
of ether vibrations constantly beating upon the surface of the body only
those waves to the velocity of which it is attuned, so each one of us as
an integral personality selects from the stream of sensory experiences
only those particular objects of attention that are in some way related
to the present or habitual trend of thought.

The Man on Broadway
Just consider for a moment the countless number and variety of
impressions that assail the eye and ear of the New Yorker who walks down
Broadway in a busy hour of the day. Yet to how few of these does he pay
the slightest attention. He is in the midst of a cataclysm of sound
almost equal to the roar of Niagara and he does not know it.

[Pg 11]
Waxen Tablets
Observe how many objects are right now in the corner of your mind’s eye
as being within the scope of your vision while your entire attention is
apparently absorbed in these lines. You see these other things, and you
can look back and realize that you have seen them, but you were not
aware of them at the time.

Let two individuals of contrary tastes take a day’s outing together.
Both may have during the day practically identical sensory images; but
each one will come back with an entirely different tale to tell of the
day’s adventures.

All sensory impressions, somehow or other, leave their faint impress on
the waxen tablets of the mind. Few are or can be voluntarily recalled.

[Pg 12]
Just where and how memories are retained is a mystery. There are
theories that represent sensory experiences as actual physiological
“impressions” on the cells of the brain. They are, however, nothing but
theories, and the manner in which the brain, as the organ of the mind,
keeps its record of sensory experiences has never been discovered.
Microscopic anatomy has never reached the point where it could identify
a particular “idea” with any one “cell” or other part of the brain.

Not How, but How Much
For us, the important question is not how, but how much; not the
manner in which, but the extent to which, sensory impressions are
preserved. Now, all the evidences indicate that absolutely every
impression received upon the sensorium
[Pg 13]
Remembering the Unperceived
is indelibly recorded in the
mind’s substance. A few instances will serve to illustrate the
remarkable power of retention of the human mind.

Sir William Hamilton quotes the following from Coleridge’s “Literaria
Biographia”: “A young woman of four- or five-and-twenty, who could
neither read nor write, was seized with a nervous fever, during which,
according to the asseverations of all the priests and monks of the
neighborhood, she became ‘possessed,’ and, as it appeared, by a very
learned devil. She continued incessantly talking Latin, Greek and Hebrew
in very pompous tones, and with most distinct enunciation. Sheets full
of her ravings were taken down from her own mouth, and were found
[Pg 14] to
consist of sentences coherent and intelligible each for itself but with
little or no connection with each other. Of the Hebrew, a small portion
only could be traced to the Bible; the remainder seemed to be in the
Rabbinical dialect.”

The case was investigated by a physician, who learned that the girl had
been a waif and had been taken in charge by a Protestant clergyman when
she was nine years old and brought up as his servant. This clergyman had
for years been in the habit of walking up and down a passage of his
house into which the kitchen door opened and at the same time reading to
himself in a loud voice from his favorite book. A considerable number of
these books were still in the possession of his niece,
[Pg 15] who told the
physician that her uncle had been a very learned man and an accomplished
student of Hebrew. Among the books were found a collection of Rabbinical
writings, together with several of the Greek and Latin fathers; and the
physician succeeded in identifying so many passages in these books with
those taken down at the bed-side of the young woman that there could be
no doubt as to the true origin of her learned ravings.

Now, the striking feature of all this, it will be observed, is the fact
that the subject was an illiterate servant-girl to whom the Greek, Latin
and Hebrew quotations were utterly unintelligible, that normally she
had no recollection of them, that she had no idea of their
[Pg 16]
Speaking a Forgotten Tongue
meaning,
and finally that they had been impressed upon her mind without her
knowledge while she was engaged in her duties in her master’s kitchen.

Several cases are reported by Dr. Abercrombie, and quoted by Professor
Hyslop, in which mental impressions long since forgotten beyond the
power of voluntary recall have been revived by the shock of accident or
disease. “A man,” he says, “mentioned by Mr. Abernethy, had been born in
France, but had spent the greater part of his life in England, and, for
many years, had entirely lost the habit of speaking French. But when
under the care of Mr. Abernethy, on account of the effects of an injury
to the head, he always spoke French.

[Pg 17]
“A similar case occurred in St. Thomas Hospital, of a man who was in a
state of stupor in consequence of an injury to the head. On his partial
recovery he spoke a language which nobody in the hospital understood but
which was soon ascertained to be Welsh. It was then discovered that he
had been thirty years absent from Wales, and, before the accident, had
entirely forgotten his native language.

“A lady mentioned by Dr. Pritchard, when in a state of delirium, spoke a
language which nobody about her understood, but which was afterward
discovered to be Welsh. None of her friends could form any conception of
the manner in which she had become acquainted with that language; but,
[Pg 18]
Living Past Experiences Over Again
after much inquiry, it was discovered that in her childhood she had a
nurse, a native of a district on the coast of Brittany, the dialect of
which is closely analogous to Welsh. The lady at that time learned a
good deal of this dialect but had entirely forgotten it for many years
before this attack of fever.”

Dr. Carpenter relates the following incident in his “Mental Physiology”:
“Several years ago, the Rev. S. Mansard, now rector of Bethnal Green,
was doing clerical duty for a time at Hurstmonceaux, in Sussex; and
while there he one day went over with a party of friends to Pevensey
Castle, which he did not remember to have ever previously visited. As he
approached the gateway he became conscious of a very
[Pg 19] vivid impression
of having seen it before; and he ‘seemed to himself to see’ not only the
gateway itself, but donkeys beneath the arch and people on top of it.
His conviction that he must have visited the castle on some former
occasion—although he had neither the slightest remembrance of such a
visit nor any knowledge of having ever been in the neighborhood
previously to his residence at Hurstmonceaux—made him inquire from his
mother if she could throw any light on the matter. She at once informed
him that being in that part of the country, when he was but eighteen
months old, she had gone over with a large party and had taken him in
the pannier of a donkey; that the elders of the party, having brought
[Pg 20]
lunch with them, had eaten it on the roof of the gateway, where they
would have been seen from below, whilst he had been left on the ground
with the attendants and donkeys.”

“An Italian gentleman,” says Dr. Rush, of Philadelphia, “who died of
yellow fever in New York, in the beginning of his illness spoke English,
in the middle of it French, but on the day of his death only Italian.”

Striking as these instances are, they are not unusual. Everyone on
reflection can supply similar instances. Who among us has not at one
time or another been impressed with a mysterious feeling of having at
some time in the past gone through the identical experience which he is
living now?

[Pg 21]
The “Flash of Inspiration”
On such occasions the sense of familiarity is sometimes so persistent as
to fill one with a strange feeling of the supernatural and to incline
our minds to the belief in a reincarnation.

The “flash of inspiration” which, for the lawyer, solves a novel legal
issue arising in the trial of a case, or, for the surgeon, sees him
successfully through the emergencies of a delicate operation, has its
origin in the forgotten learning of past experience and study.

Succeeding books in this Course will bring to light numerous other
facts less commonly observed, drawn indeed from the study of abnormal
mental states, indicating that we retain a great volume of
sense-impressions of whose very recording we are at the time unaware.
[Pg 22]
The Totality of Retention
In other words, all the evidences point to the absolute totality of our
retention of all sensory experiences. They indicate that every
sense-impression you ever received, whether you actually perceived and
were conscious of it or not, has been retained and preserved in your
memory, and can be “brought to mind” when you understand the proper
method of calling it into service.

A vast wealth of facts is stored in the treasure vaults of your mind,
but there are certain inner compartments to which you have lost the
combination.

The author of “Thoughts on Business” says: “It is a great day in a man’s
life when he truly begins to discover himself. The latent capacities of
every
[Pg 23]
Possibilities of Self-Discovery
man are greater than he realizes, and he may find them if he
diligently seeks for them. A man may own a tract of land for many years
without knowing its value. He may think of it as merely a pasture. But
one day he discovers evidences of coal and finds a rich vein beneath his
land. While mining and prospecting for coal he discovers deposits of
granite. In boring for water he strikes oil. Later he discovers a vein
of copper ore, and after that silver and gold. These things were there
all the time—even when he thought of his land merely as a pasture. But
they have a value only when they are discovered and utilized.”

“Not every pasture contains deposits of silver and gold, neither oil
nor
[Pg 24]
“Acres of Diamonds”
granite, nor even coal. But beneath the surface of every man there
must be, in the nature of things, a latent capacity greater than has yet
been discovered. And one discovery must lead to another until the man
finds the deep wealth of his own possibilities. History is full of the
acts of men who discovered somewhat of their own capacity; but history
has yet to record the man who fully discovered all that he might have
been.”

You who are a bit vain of your visits to other lands, your wide reading,
your experience of men and things; you who secretly lament that so
little of what you have seen and read remains with you, behold, your
“acres of diamonds” are within you, needing but the mystic formula that
shall reveal the treasure!

[Pg 25]
[Pg 26]

THE MECHANISM OF RECALL

[Pg 27]

Chapter III

THE MECHANISM OF RECALL

The Right Stimulus
Somehow, somewhere, all experiences, whether subject to voluntary recall
or not, are preserved, and are capable of reproduction when the right
stimulus comes along.

And it is a law that those experiences which are associated with each
other, whether ideas, emotions or voluntary or involuntary muscular
movements, tend to become bound together into groups, and these groups
tend to become bound together into systems.

[Pg 28]
“Complexes” of Experience
Such a system of associated groups of experiences is technically known
as a “complex.”

Pay particular attention to these definitions, as “groups” of ideas and
“complexes” of ideas, emotions and muscular movements are terms that we
shall constantly employ.

You learned in a former lesson that mental experiences may consist not
only of sense-perceptions based on excitements arising in the memory
nerves, but also of bodily emotions, the “feeling tones” of ideas, and
of muscular movements based on stimuli arising in the motor nerves.

Groups consist, therefore, not only of associated ideas, but of
associated ideas coupled with their emotional
[Pg 29]
The Thrill of Recollection
qualities and impulses to
muscular movements.

All groups bound together by a mutually related idea constitute a single
“complex.” Every memory you have is an illustration of such “complexes.”

Suppose, for example, you once gained success in a business deal. Your
recollection of the other persons concerned in that transaction, of any
one detail in the transaction itself, will be accompanied by the faster
heartbeat, the quickened circulation of the blood, the feeling of
triumph and elation that attended the original experience.

Complexes formed out of harrowing earthquakes, robberies, murders or
other dreadful spectacles, which were originally accompanied on the part
of
[Pg 30]
“Complexes” and Functional Derangements
the onlooker by trembling, perspiration and palpitation of the
heart, when lived over again in memory, are again accompanied by all
these bodily activities. Your memory of a hairbreadth escape will bring
to your cheek the pallor that marked it when the incident occurred.

The formation and existence of “complexes” explains the origin of many
functional diseases of the body—that is to say, diseases involving no
loss or destruction of tissue, but consisting simply in a failure on the
part of some bodily organ to perform its allotted function naturally and
effectively.

Thus, in hay fever or “rose cold” the tears, the inflammation of the
membranes of the nose, the cough, the other trying symptoms, all are
linked with
[Pg 31]
Automatically Working Mental Mechanisms
the sight of a rose, or dust, or sunlight, or some other
outside fact to which attention has been called as the cause of hay
fever, into a complex, “an automatically working mechanism.” And the
validity of this explanation of the regular recurrence of attacks of
this disease is sufficiently demonstrated by the fact that a paper rose
is likely to prove just as effective in producing all the symptoms of
the disease as a rose out of Nature’s garden.

Another striking illustration of the working of this principle is
afforded by two gentlemen of my acquaintance, brothers, each of whom
since boyhood has had unfailing attacks of sneezing upon first arising
in the morning. No sooner is one of these men awake and
[Pg 32]
Two Classes of “Complexes”
seated upon the
edge of his bed for dressing than he begins to sneeze, and he continues
to sneeze for fifteen or twenty minutes thereafter, although he has no
“cold” and never sneezes at any other time.

Obviously, if absolutely all mental experiences are preserved, they
consist altogether of two broad classes of complexes: first, those that
are momentarily active in consciousness, forming part of the present
mental picture, and, second, all the others—that is to say, all past
experiences that are not at the present moment before the mind’s eye.

There are, then, conscious complexes and subconscious complexes,
complexes of consciousness and complexes of subconsciousness.

[Pg 33]
The Subconscious Storehouse
And of the complexes of subconsciousness, some are far more readily
recalled than others. Some are forever popping into one’s thoughts,
while others can be brought to the light of consciousness only by some
unusual and deep-probing stimulus. And the human mind is a vast
storehouse of complexes, far the greater part buried in
subconsciousness, yet somehow, like impressions on the wax cylinder of
a phonograph, preserved with life-like truth and clearness.

Turn back for a moment to our definition of memory. You will observe
that its second essential element is Recall.

Recall is the process by which the experiences of the past are summoned
[Pg 34]
from the reservoir of the subconscious into the light of present
consciousness. We necessarily touched upon this process in a previous
book, in considering the Laws of Association, but here, in relation to
memory, we shall go into the matter somewhat more analytically.

[Pg 35]
[Pg 36]

THE LAWS OF RECALL

[Pg 37]

Chapter IV

THE LAWS OF RECALL

The Law of Integral Recall
Law I. The primary law of recall is this: The recurrence or
stimulation of one element in a complex tends to recall all the others.

In our explanation of “complex” formation we necessarily cited instances
that illustrate this principle as well, since recall is merely a
reverse operation from that involved in “complex” formation.

For example, in running through a book I come upon a flower pressed
between its pages. At once the memory
[Pg 38]
What Ordinary “Thinking” Amounts to
of the friend who gave it to me
springs into consciousness and becomes the subject of reminiscence. This
recalls the mountain village where we last met. This recalls the fact
that a railroad was at the time under process of construction, which
should transform the village into a popular resort. This in turn
suggests my coming trip to the seashore, and I am reminded of a business
appointment on which my ability to leave town on the appointed day
depends. And so on indefinitely.

Far the greater part of your successive states of consciousness, or even
of your ordinary “thinking,” commonly so-called, consists of trains of
mental pictures “suggested” one by another. If the associated pictures
are of the everyday
[Pg 39]
The Reverse of Complex Formation
type, common to everyone, you have a prosaic mind;
if, on the other hand, the associations are unusual or unique, you are
happily possessed of wit and fancy.

These instances of the action of the Law of Recall illustrate but one
phase of its activity. They show simply that groups of ideas are so
strung together on the string of some common element that the activity
of one “group” in consciousness is apt to be automatically followed by
the others. But the law of association goes deeper than this. It enters
into the activity of every individual group, and causes all the elements
of every group, ideas, emotions and impulses to muscular movements, to
be simultaneously manifested.

[Pg 40]
Prolixity and Terseness
There is no principle to which we shall more continually refer than this
one. Our explanation of hay fever a moment ago illustrates our meaning.
Get the principle clearly in your mind, and see how many instances of
its operation you can yourself supply from your own daily experience.

So far as the mere linking together of groups of ideas is concerned,
this classifying quality is developed in some persons to a greater
degree than in others. It finds its extreme exemplar in the type of man
who can never relate an incident without reciting all the prolix and
minute details and at the same time wandering far from the original
subject in pursuit of every suggested idea.

[Pg 41]
The Law of Contiguity
Law II. Similarity and nearness in time or space between two
experiential facts causes the thought of one to tend to recall the
thought of the other.

This is the Associative Law of Contiguity considered from the standpoint
of recall. The points of contiguity are different for different
individuals. Similarities and nearnesses will awaken all sorts of
associated groups of ideas in one person that are not at all excitable
in the same way in another whose experiences have been different.

Law III. The greater the frequency and intensity of any given
experience, the greater the ease and likelihood of its reproduction and
recall.

This explains why certain groups in
[Pg 42]
Laws of Habit and Intensity
any complex are more readily
recalled than others—why some leap forth unbidden, why some come next
and before others, why some arrive but tardily or not at all.

This is how the associative Laws of Habit and Intensity affect the power
of recall.

There is no department of business to which the application of these
Laws of Recall is so apparent as the department of advertising. The most
carefully worded and best-illustrated advertisement may fail to pay its
cost unless the underlying principles of choice of position, selection
of medium and size of space are understood. The advertisers in
metropolitan newspapers
[Pg 43]
Applications to Advertising
and magazines of large circulation are the ones
who have most at stake. But whatever the field to be reached, it is well
to bear in mind certain facts based on the Laws of Recall that have been
established by psychological experiment.

Most advertisers have a general idea that certain relative positions on
the newspaper or magazine page are to be preferred over others, but they
have no conception of the real differences in relative recall value.
When the great cost of space in large publications is considered the
financial value of such knowledge is evident.

By a great number of tests the relative recall value of every part of
the newspaper page has been approximately
[Pg 44]
Effect of Repetitions
determined. It has been
found, for example, that a given space at the upper right-hand corner of
the page has more than twice the value of the same amount of space in
the lower left-hand corner.

Many advertisers adopt the policy of repeating full-page advertisements
at long intervals instead of advertising in a small way continually.
Laboratory tests have shown, on the contrary, that a quarter-page
advertisement appearing in four successive issues of a newspaper is
fifty per cent more effective than a full-page advertisement appearing
only once. It does not follow, however, that an eighth-page
advertisement repeated eight times is correspondingly more effective;
for below a certain relative size the value of an advertisement
[Pg 45]
Ratio of Size to Value
decreases much more rapidly than the cost. There are, of course,
modifying conditions, such as special sales of department stores, where
occasional displays and announcements make it desirable to use either
full pages, or even double pages, but the great bulk of advertising is
not of this character.

Every year in the United States alone six hundred millions of dollars
are expended in advertising the sale of commodities, and for the most
part expended in a haphazard, experimental and unscientific way. The
investment of this vast sum with risk of perhaps total loss, or even
possible injury, through the faulty construction or improper placing of
advertisements should stimulate the interest of every [Pg 46]
Risks in Advertising
advertiser in the
work that psychologists have done and are doing toward the accumulation
of a body of exact knowledge on this subject.

[Pg 48]

TESTING THE MEMORY

[Pg 49]

Chapter V

THE SCIENCE OF FORGETTING

The Skilled Artisan
Attention is the instrumentality through which the Laws of Recall
operate. Wittingly or unwittingly, consciously or unconsciously, every
man’s attention swings in automatic obedience to the Laws of Recall.

Attention is the artisan that, bit by bit, and with lightning quickness,
constructs the mosaic of consciousness.

Having the whole vast store of all present and past experiences to draw
upon, he selects only those groups and
[Pg 50]
How the Attention Works
those isolated instances that
are related to our general interests and aims. He disregards others.

The attention operates in a manner complementary to the general Laws of
Recall. It is an active principle not of association, but of
dissociation.

You choose, for example, a certain aim in life. You decide to become the
inventor of an aeroplane of automatic stability. This choice henceforth
determines two things. First, it determines just which of the sensory
experiences of any given moment are most likely to be selected for your
conscious perception. Secondly, it determines just which of your past
experiences will be most likely to be recalled.

Such a choice, in other words, determines
[Pg 51]
Iron Filings and Mental Magnets
to some extent the sort of
elements that will most probably be selected to make up at any moment
the contents of your consciousness.

From the instant that you make such a choice you are on the alert for
facts relevant to the subject of your ambition. Upon them you
concentrate your attention. They are presented to your consciousness
with greater precision and clearness than other facts. All facts that
pertain to the art of flying henceforth cluster and cling to your
conscious memory like iron filings to a magnet. All that are impertinent
to this main pursuit are dissociated from these intensely active
complexes, and in time fade into subconscious forgetfulness.

By subconscious forgetfulness we
[Pg 52]
The Compartment of Subconscious Forgetfulness
mean a compartment, as it were, of
that reservoir in which all past experiences are stored.

Consciousness is a momentary thing. It is a passing state. It is
ephemeral and flitting. It is made up in part of present
sense-impressions and in part of past experiences. These past
experiences are brought forth from subconsciousness. Some are
voluntarily brought forth. Some present themselves without our conscious
volition, but by the operation of the laws of association and
dissociation. Some we seem unable voluntarily to recall, yet they may
appear when least we are expecting them. It is these last to which we
have referred as lost in subconscious forgetfulness. As a matter of
fact, none are ever actually lost.

[Pg 53]
Making Experience Count
All the wealth of your past experience is still yours—a concrete part
of your personality. All that is required to make it available for your
present use is a sufficient concentration of your attention, a
concentration of attention that shall dwell persistently and exclusively
upon those associations that bear upon the fact desired.

The tendency of the mind toward dissociation, a function limiting the
indiscriminate recall of associated “groups,” is also manifested in all
of us in the transfer to unconsciousness of many muscular activities.

As infants we learn to walk only by giving to every movement of the
limbs the most deliberate conscious attention. Yet, in time, the
complicated co-operation
[Pg 54]
How Habits Are Formed
of muscular movements involved in walking
becomes involuntary and unconscious, so that we are no longer even aware
of them.

It is the same with reading, writing, playing upon musical instruments,
the manipulation of all sorts of mechanical devices, the thousand and
one other muscular activities that become what we call habitual.

The moment one tries to make these habitual activities again dependent
on the conscious will he encounters difficulties.

[Pg 55]
All these habitual activities are started as acts of painstaking care
and conscious attention. All ultimately become unconscious. They may,
however, be started or stopped at will. They are, therefore, still
related to the conscious mind. They occupy a semi-automatic middle
ground between conscious and subconscious activities.

[Pg 56]
[Pg 57]

THE FALLACY OF MOST MEMORY SYSTEMS

[Pg 58]

[Pg 59]

Chapter VI

THE FALLACY OF MOST MEMORY SYSTEMS

Practice in Memorizing Inadequate
It is evident that if what we have been describing as the process of
recall is true, then the commonly accepted idea that practice in
memorizing makes memorizing easier is false, and that there is no
truth in the popular figure of speech that likens the memory to a muscle
that grows stronger with use.

So far as the memory is concerned, however, practice may result in a
more or less unconscious improvement in the methods of memorizing.

[Pg 60]
Torture of the Drill
By practice we come to unconsciously discover and employ new
associative methods in our recording of facts, making them easier to
recall, but we can certainly add nothing to the actual scope and power
of retention.

Yet many books on memory-training have wide circulation whose authors,
showing no conception of the processes involved, seek to develop the
general ability to remember by incessant practice in memorizing
particular facts, just as one would develop a muscle by exercise.

The following is quoted from a well-known work of this character:

“I am now treating a case of loss of memory in a person advanced in
years, who did not know that his memory had
[Pg 61] failed most remarkably
until I told him of it. He is making vigorous efforts to bring it back
again, and with partial success. The method pursued is to spend two
hours daily, one in the morning and one in the evening, in exercising
this faculty. The patient is instructed to give the closest attention to
all that he learns, so that it shall be impressed on his mind clearly.
He is asked to recall every evening all the facts and experiences of the
day, and again the next morning. Every name heard is written down and
impressed on his mind clearly and an effort made to recall it at
intervals. Ten names from among public men are ordered to be committed
to memory every week. A verse of poetry is to be learned, also a
[Pg 62]
Real Cause of Failing Memory
verse
from the Bible, daily. He is asked to remember the number of the page of
any book where any interesting fact is recorded. These and other
methods are slowly resuscitating a failing memory.”

As remarked by Professor James, “It is hard to believe that the memory
of the poor old gentleman is a bit the better for all this torture
except in respect to the particular facts thus wrought into it, the
occurrences attended to and repeated on those days, the names of those
politicians, those Bible verses, etc., etc.”

The error in the book first quoted from lies in the fact that its author
looks upon a failing memory as indicating a loss of retentiveness. The
real cause is the loss of an intensity of interest. It is the failure
to form sufficiently large
[Pg 63]
The Manufactured Interest
groups and complexes of related ideas,
emotions and muscular movements associated with the particular fact to
be remembered. There is no reason to believe that the retention of
sensory experiences is not at all times perfectly mechanical and
mechanically perfect.

Interest is a mental yearning. It is the offspring of desire and the
mother of memory.

It goes out spontaneously to anything that can add to the sum of one’s
knowledge about the thing desired.

A manufactured interest is counterfeit. When a thing is done because it
has to be done, desire dies and “duty” is born. In proportion as a
subject is associated with “duty,” it is divorced from interest.

[Pg 64]
Memory Lure of a Desire
If you want to impress anything on another man’s mind so that he will
remember it, harness it up with the lure of a desire.

Diffused interest is the cause of all unprofitable forgetfulness. Do not
allow your attention to grope vaguely among a number of things. Whatever
you do, make a business of doing it with your whole soul. Turn the
spotlight of your mind upon it, and you will not forget it.

A SCIENTIFIC MEMORY SYSTEM FOR BUSINESS SUCCESS

Importance of Associates
We recall things by their associates. When you set your mind to
remember any particular fact, your conscious effort should be not
vaguely to will that it shall be impressed and retained, but
analytically and deliberately to connect it with one or more other facts
already in your mind.

The student who “crams” for an examination makes no permanent addition
[Pg 68]
“Cramming” and “Willing”
to his knowledge. There can be no recall without association, and
“cramming” allows no time to form associations.

If you find it difficult to remember a fact or a name, do not waste your
energies in “willing” it to return. Try to recall some other fact or
name associated with the first in time or place or otherwise, and lo!
when you least expect it, it will pop into your thoughts.

If your memory is good in most respects, but poor in a particular line,
it is because you do not interest yourself in that line, and therefore
have no material for association. Blind Tom’s memory was a blank on most
subjects, but he was a walking encyclopedia on music.

[Pg 69]
Basic Principle of Thought-Reproduction
To improve your memory you must increase the number and variety of your
mental associations.

Many ingenious methods, scientifically correct, have been devised to aid
in the remembering of particular facts. These methods are based wholly
on the principle that that is most easily recalled which is associated
in our minds with the most complex and elaborate groupings of related
ideas.

Thus, Pick, in “Memory and Its Doctors,” among other devices, presents a
well-known “figure-alphabet” as of aid in remembering numbers. Each
figure of the Arabic notation is represented by one or more letters, and
the number to be recalled is translated into such letters as can best be
arranged [Pg 70]
Methods of Pick
into a catch word or phrase. To quote: “The most common
figure-alphabet is this:

“To briefly show its use, suppose it is desired to fix 1,142 feet in a
second as the velocity of sound, t, t, r, n, are the letters and order
required. Fill up with vowels forming a phrase like ‘tight run’ and
connect it by some such flight of the imagination as that if a man tried
to keep up with the velocity of sound, he would have a ‘tight run.'”

The same principle is at the basis of all efficient pedagogy. The
competent
[Pg 71]
Scientific Pedagogy
teacher endeavors by some association of ideas to link every
new fact with those facts which the pupil already has acquired.

In the pursuit of this method the teacher will “compare all that is far
off and foreign to something that is near home, making the unknown plain
by the example of the known, and connecting all the instruction with the
personal experience of the pupil—if the teacher is to explain the
distance of the sun from the earth, let him ask, ‘If anyone there in the
sun fired off a cannon straight at you, what should you do?’ ‘Get out of
the way,’ would be the answer. ‘No need of that,’ the teacher might
reply; ‘you may quietly go to sleep in your room and get up
[Pg 72]
How to Remember Names
again; you
may wait till your confirmation day, you may learn a trade, and grow as
old as I am—then only will the cannon-ball be getting near, then
you may jump to one side! See, so great as that is the sun’s distance!'”

We shall now show you how to apply this principle in improving your
memory and in making a more complete use of your really vast store of
knowledge.

Rule I. Make systematic use of your sense-organs.

Do you find it difficult to remember names? It is because you do not
link them in your mind with enough associations. Every time a man is
introduced to you, look about you. Who is
[Pg 73] present? Take note of as many
and as great a variety of surrounding facts and circumstances as
possible. Think of the man’s name, and take another look at his face,
his dress, his physique. Think of his name, and at the same time his
voice and manner. Think of his name, and mark the place where you are
now for the first time meeting him. Think of his name in conjunction
with the name and personality of the friend who presented him.

Memory is not a distinct faculty of mind in the sense that one man is
generously endowed in that respect while another is deficient. Memory,
as meaning the power of voluntary recall, is wholly a question of
trained habits of mental operation.

[Pg 74]
Five Exercises for Developing Observation
Your memory is just as good as mine or any other man’s. It is your
indifference to what you would call “irrelevant facts” that is at fault.
Therefore, cultivate habits of observation. Fortify the observed facts
you wish to recall with a multitude of outside associations. Never rest
with a mere halfway knowledge of things.

To assist you in training yourself in those habits of observation that
make a good memory of outside facts, we append the following exercises:

a. Walk slowly through a room with which you are not familiar. Then
make a list of all the contents of the room you can recall. Do this
every day for a week, using a different room each time. Do it not
half-heartedly, but as if your
[Pg 75] life depended on your ability to
remember. At the end of the week you will be surprised at the
improvement you have made.

b. As you walk along the street, observe all that occurs in a space of
one block, things heard as well as things seen. Two hours later make a
list of all you can recall. Do this twice a day for ten days. Then
compare results.

c. Make a practice of recounting each night the incidents of the day.
The prospect of having this to do will cause you unconsciously to
observe more attentively.

This is the method by which Thurlow Weed acquired his phenomenal memory.
As a young man with political ambitions he had been much
[Pg 76] troubled by
his inability to recall names and faces. So he began the practice each
night of telling his wife the most minute details of incidents that had
occurred during the day. He kept this up for fifty years, and it so
trained his powers of observation that he became as well known for his
unfailing memory as for his political adroitness.

d. Glance once at an outline map of some State. Put it out of sight
and draw one as nearly like it as you can. Then compare it with the
original. Do this frequently.

e. Have some one read you a sentence out of a book and you then repeat
it. Do this daily, gradually increasing the length of the quotation from
short sentences to whole paragraphs. Try to
[Pg 77]
Invention and Thought-Memory
find out what is the
extreme limit of your ability in this respect compared with that of
other members of your family.

Rule II. Fix ideas by their associates.

There are other things to be remembered besides facts of outside
observation. You are not one whose life is passed entirely in a physical
world. You live also within. Your mind is unceasingly at work with the
materials of the past painting the pictures of the future. You are
called upon to scheme, to plan, to devise, to invent, to compose and to
foresee.

If all this mental work is not wasted energy, you must be able to recall
its
[Pg 78]
Three Exercises for Developing Thought-Memory
conclusions when occasion requires. A happy thought comes to
you—will you remember it tomorrow when the hour for action arrives?
There is but one way to be sure, and that is by making a study of the
whole associative mental process.

Review the train of ideas by which you reached your conclusion. Carry
the thought on in mind to its legitimate conclusion. See yourself acting
upon it. Mark its relations to other persons. Note all the details of
the mental picture. In other words, to remember thoughts, cultivate
thought-observation just as you cultivate sense-observation to remember
outside matters.

To train yourself in thought-memory, use the following exercises:

[Pg 79]
a. Every morning at eight o’clock, sharp on the minute, fix upon a
certain idea and determine to recall it at a certain hour during the
day. Put your whole will into this resolution. Try to imagine what
activities you will be engaged in at the appointed hour, and think of
the chosen idea as identified with those activities. Associate it in
your mind with some object that will be at hand when the set time comes.
Having thus fixed the idea in your mind, forget it. Do not refer to it
in your thoughts. With practice you will find yourself automatically
carrying out your own orders. Persist in this exercise for at least
three months.

b. Every night when you retire fix upon the hour at which you wish to
get
[Pg 80] up in the morning. In connection with your waking at that hour,
think of all the sounds that will be apt to be occurring at that
particular time. Bar every other thought from your consciousness and
fall asleep with the intense determination to arise at the time set. By
all means, get up instantly when you awaken. Keep up this exercise and
you will soon be able to awaken at any hour you may wish.

c. Every morning outline the general plan of your activities for the
day. Select only the important things. Do not bother with the details.
Determine upon the logical order for your day’s work. Think not so much
of how you are to do things as of the things you are to do. Keep
your mind on results. And
[Pg 81]
How to Compel Recollection
having made your plan, stick to it. Be your
own boss. Let nothing tempt you from your set purpose. Make this daily
planning a habit and hold to it through life. It will give you a great
lift toward whatever prize you seek.

Rule III. Search systematically and persistently.

When once you have started upon an effort at recollection, persevere.
The date or face or event that you wish to recall is bound up with a
multitude of other facts of observation and of your mind life of the
past. Success in recalling it depends simply upon your ability to hit
upon some idea so indissolubly associated with the object of search that
the recall of one automatically recalls
[Pg 82]
Formation of Correct Memory Habits
the other. Consequently the
thing to do is to hold your attention to one definite line of thought
until you have exhausted its possibilities. You must pass in review all
the associated matters and suppress or ignore them until the right one
comes to mind. This may be a short-cut process or a roundabout process,
but it will bring results nine times out of ten, and if habitually
persisted in will greatly improve your power of voluntary recall.

Rule IV. The instant you recollect a thing to be done, do it.

Every idea that memory thrusts into your consciousness carries with it
the impulse to act upon it. If you fail to do so, the matter may not
again occur
[Pg 83]
NOW!
to you, or when it does it may be too late.

Your mental mechanism will serve you faithfully only as long as you act
upon its suggestions.

This is as true of bodily habits as of business affairs. The time to act
upon an important matter that just now comes to mind is not “tomorrow”
or a “little later,” but NOW.

What you do from moment to moment tells the story of your career. Ideas
that come to you should be compared as to their relative importance. But
do this honestly. Do not be swayed by distracting impulses that
inadvertently slip in. And having gauged their importance give free rein
at once to the impulse to do everything that
[Pg 84]
Persistence, Accuracy, Dispatch
should not make way for
something more important.

If, for any reason, action must be deferred, fix the matter in your mind
to be called up at the proper time. Drive all other thoughts from your
consciousness. Give your whole attention to this one matter. Determine
the exact moment at which you wish it to be recalled. Then put your
whole self into the determination to remember it at precisely the right
moment. And finally, and perhaps most important of all,—

Rule V. Have some sign or token. This memory signal may be
anything you choose, but it must somehow be directly connected with the
hour at which the main event is to be recalled.

Make a business of observing the
[Pg 85]
Memory Signs and Tokens
memory signs or tokens you have been
habitually using. Practice tagging those matters you wish to recall with
the labels that form a part of your mental machinery.

Make it a habit to do things when they ought to be done and in the order
in which you ought to do them. Habits like this are “paths” along which
the mind “moves,” paths of least resistance to those qualities of
promptness, energy, persistence, accuracy, self-control, and so on, that
create success.

Success in business, success in life, can come only through the
formation of right habits. A right habit can be deliberately acquired
only by doing a thing consciously until it comes to be done
unconsciously and automatically.

[Pg 86]
The Mental Combination Revealed
Every man, consciously or unconsciously, forms his own memory habits,
good or bad. Form your memory habits consciously according to the laws
of the mind, and in good time they will act unconsciously and with
masterful precision.

“‘Amid the shadows of the pyramids,’ Bonaparte said to his soldiers,
‘twenty centuries look down upon you,’ and animated them to action and
victory. But all the centuries,” says W.H. Grove, “and the eternities,
and God, and the universe, look down upon us—and demand the highest
culture of body, mind and spirit.”

A good memory is yours for the making. But you must make it. We can
point the way. You must act.

[Pg 87]
The laws of Association and Recall are the combination that will unlock
the treasure-vaults of memory. Apply these laws, and the riches of
experience will be available to you in every need.

The purpose of this book has been to make clear certain mental
principles and processes, namely, those of Retention, Association and
Recall. Incidentally, as with every book in this Course, it contains
some facts and instructions of immediate practical utility. But
primarily it is intended only to help prepare your mind to understand a
scientific system for success-achievement that will be unfolded in
subsequent volumes.
