It is a wise provision of nature that the perceptive powers and the

mechanical memory are most active in childhood and youth. The normal

child is hungry for words and facts, and gathers information from every

conceivable quarter. The judgment and the reason develop after the mind

has been stored with the materials upon which these may act. Parents

and teachers who are ignorant of this order of development often force

the reasons for arithmetical processes upon the pupil when these are

difficult and when he could learn the eleven hundred variations of the

Greek verb without difficulty, whilst the study of the classical and

foreign languages is postponed to an age when the acquisition of a

new language becomes a difficult task because the logical memory has

driven the mechanical into the background, and the growth of judgment

and reason makes the pupil crave the intellectual food furnished by

the thought-studies. It is a species of cruelty to force upon children

the consideration of the why’s and the wherefore’s of mathematical

operations, when learning how to go through the motions would be quite

enough of a tax upon their mental strength. Some of the demonstrations

in arithmetic are logically more difficult than many of the proofs in

geometry; hence no pupil should be asked to pass his final examination in

arithmetic before he has mastered the elements of geometry. The proper

sequence of subjects is of immense importance in leading the child

from the lower to the higher forms of intellectual activity. With the

proper study of geometry the logical memory steps to the front, and the

thought-studies should then supplant those which largely appeal to the

mechanical memory.

Nevertheless, it is a distinct loss if the verbal or mechanical memory is

ever allowed to drop into desuetude. On this point the practice, as well

as the testimony, of Dr. W. T. Harris is worthy of the attention of every

person charged with the training of himself or others.

[Sidenote: Harris on the memory.]

“If a person finds himself forgetful of names, it is a health-giving

process to take a certain portion of time in committing to memory

words. If this is done by committing new masterpieces of poetry and

prose, or in committing to memory the words of a new language, there

is profit or gain to the thinking powers, as well as to the memory.

Doubtless the cultivation of verbal memory, building up, as it does,

a certain convolution in the brain, has a tendency to prevent atrophy

in that organ. This contains a hint in the direction of keeping up in

the later part of life the faculties which are usually so active in

youth. The tendency is to neglect childish faculties and allow them to

become torpid. But if this is liable to weaken certain portions of the

brain in such a way as to induce hemorrhage, ending in softening of the

brain, certainly the memory should be cultivated, if only for the health

of the brain, and the memory for mechanical items of detail should be

cultivated on grounds of health as well as on grounds of culture. The

extreme advocates of the rational method of teaching are perhaps wrong in

repudiating entirely all mechanical memory of dates and names or items.

Certainly they are right in opposing the extremes of the old pedagogy,

which obliged the pupils to memorize, page after page, the contents of

a grammar _verbatim et literatim et punctuatim_ (as, for instance, the

graduates of the Boston Latin School tell us was the custom early in

this century). But is there not a middle ground? Is there not a minimum

list of details, of dates and names which must and should be memorized,

both on account of the health of the nervous system and on account of

the intrinsic usefulness of the data themselves? And must not the person

in later life continue to exercise these classes of memory which deal

with details for the sake of physical health? This is a question for the

educational pathologist.”[23]

[Sidenote: Vocabularies.]

A teacher of Hebrew spent one-fourth of his time in drill on Hebrew roots

and their meaning. His students groaned under the drudgery imposed. At

the end of the first six chapters of Genesis, he surprised his class by

the announcement, “Now you know half the words in the Hebrew Bible.”

He had selected words used five hundred times, then words used three

hundred times, and drilled on these in various ways until he had fixed

all the words in most frequent use in the Hebrew text. It was a great

saving of time in the end, and a great step towards reading at sight the

Old Testament in the original. By the modern short-cuts to knowledge

the pupils are hurried from one classic author to another, and hence

they never master the vocabulary to the extent of reading Latin or Greek

at sight. A little less haste at the start, and a little more drill

for the purpose of fixing new words as they come up, thus avoiding the

everlasting turning to the lexicon for more than half the words in a

lesson, would facilitate progress and enable the student to find some

pleasure in the study of foreign languages.

[Sidenote: Teaching languages.]

An old teacher of Latin, who had discovered this secret in the

acquisition of a foreign tongue, agreed to take a small class in Livy

on condition that the students write in a special blank-book and review

every day all the words whose meaning they were required to hunt in the

lexicon. At the end of ten weeks half the class read two pages without

looking up more than two words. Their study of Latin not only gave them

a sense of pleasure, but, in thinking the thoughts of the author through

the medium of the eye-symbols and then putting them into good English,

they acquired excellent thought-material, an extensive vocabulary, and

superior skill in syntactical construction. It proved a most valuable

exercise in thinking and in the expression of thought.

[Sidenote: Logical memory.]

Valuable as the mechanical memory is for the purpose of furnishing the

thought-instruments, it sinks into comparative insignificance alongside

of the logical memory. The latter is the memory for ideas, binding them

by associations based on cause and effect, reason and consequence,

similarity and contrast, the general and the particular. It is the kind

of memory by which the mind carries a knowledge of the laws of science,

the principles of art, the salient points of a discourse, the train of

ideas in a book, the leading thoughts in a system of philosophy. It

converts history and geography from a dry collection of facts, dates,

and names into a living organism whose parts are internally related by a

plastic principle, and combined into a whole that has order and system

in every detail. How much better that a pupil’s knowledge of history

and geography should be thus systematized than that it should resemble

a wilderness of facts! As a means for furnishing thought-material, the

logical memory is far more valuable than the memory which holds words and

things by the accidental ties of sound, sight, and fanciful relations.

[Sidenote: Latham’s classification.]

A classification of the forms of memory into portative, analytical, and

assimilative, given in Latham’s book on the “Action of Examinations,” is

helpful in determining the relation of memory to thinking.

[Sidenote: Portative memory.]

The portative memory simply conveys matter. “Its only aim, like that

of a carrier, is to deliver the parcel as it was received.” It is the

form of memory that enables some people to carry the contents of entire

volumes in their minds, sometimes in the very words, oftener in ideas

only. The rhapsodists in ancient Greece who could repeat entire books of

Homer are examples in point. Some men of superior talent have possessed

this power in an eminent degree. Macaulay, on a voyage across the Irish

Channel, rehearsed from memory an entire book of Virgil’s “Æneid.” It is

the kind of memory that shines at examinations and excites the envy of

persons less gifted with powers of retention. It may easily be degraded

into a slave, doing work which should be performed by higher mental

powers. Hence it has been appropriately styled the Cinderella faculty

of the mind. Like the girl in the story, it may be abused dreadfully by

having all sorts of useless drudgery heaped upon it. To require a child

to learn the five thousand isolated facts formerly scattered through

treatises on geography was an exercise as useless as the picking of the

lentils which were poured into the ashes to give Cinderella something to

do, and, unfortunately, there is no bird from fairyland to assist in the

accomplishment of the task.

Much as we may admire the power of Thomas Fuller, who could repeat five

hundred unrelated words in foreign languages after hearing them twice, it

is an accomplishment not worth acquiring. As an accomplishment it recalls

the king to whom a man exhibited his skill in throwing a pea so that it

would stick on the end of a pin,—a feat acquired after years of patient

practice. The man hoped to get a valuable present for his exhibition of

skill. The king ordered a bag of pease to be given him, saying that it

was all his accomplishment was worth.

There is no end of warnings as to the possible evil effects of a good

memory upon the power to think,—warnings that a teacher may take to heart

with advantage to himself and others.

[Sidenote: Memory and the understanding.]

Dr. Carpenter asserts that when the form of memory by which children

learn a piece of poetry whose meaning they do not comprehend exists in

unusual strength, it seems to impede rather than aid the formation of the

nexus of associations which makes acquired knowledge a part of the mind

itself. In illustration, he cites the suggestive case of Dr. Leyden, “who

was distinguished for his extraordinary gift of learning languages, and

who could repeat long acts of Parliament, or any similar document, after

having once read it. Being congratulated by a friend on his remarkable

gift, he replied that, instead of being an advantage to him, it was often

a source of great inconvenience, because, when he wished to recollect

anything in a document he had read, he could only do it by repeating

the whole from the commencement till he reached the point he wished to

recall.”

Latham has well said, “The ready mechanical memory of a youth, besides

enabling him to mislead unpractised examiners, makes him deceive himself.

Teachers find that a very ready memory is a bad educator; it stunts the

growth of other mental powers by doing their work for them. A youth who

can recollect without trouble will, as it were, mask the difficulty in

his classical author or his mathematics by learning by rote what stands

in his translation or text-book, and march forward without more ado. Thus

a quick memory involves a temptation which may enervate its possessor

by suffering him to evade a difficulty instead of bracing himself to

encounter it in front.”[24]

Maudsley writes in the same strain: “This kind of memory, in which

the person seems to read a photographic copy of former impressions

with his mind’s eye, is not, indeed, commonly associated with high

intellectual power; for what reason I know not, unless it be that the

mind, to which it belongs, is prevented, by the very excellence of its

power of apprehending and recalling separate facts, from rising to

that discernment of their relations which is involved in reasoning and

judgment, and so stays in a function which should be the foundation of

further development, or that, being by some natural defect prevented from

rising to the higher sphere of a comprehension of relations, it applies

all its energies to a comprehension of details. Certainly one runs the

risk, by overloading the memory of a child with details, of arresting the

development of the mental powers of the child; stereotyping details on

the brain, we prevent that further development of it which consists in

rising from concrete conceptions to the conception of relations.”[25]

Here is another warning from the pen of Archbishop Whately:

“Some people have been intellectually damaged by having what is called

a good memory. An unskilful teacher is content to put before children

all they ought to learn, and to take care that they remember it; and so,

though the memory is retentive, the mind is left in a passive state, and

men wonder that he who was so quick at learning and remembering should

not be an able man, which is as reasonable as to wonder that a cistern if

filled should not be a perpetual fountain. Many men are saved by their

deficiency of memory from being spoiled by an education; for those who

have no extraordinary memory are driven to supply its place by thinking.

If they do not remember a mathematical demonstration, they are driven to

devise one. If they do not remember what Aristotle or Bacon said, they

are driven to consider what they are likely to have said or ought to have

said.”[26]

In his letter to a student who lamented his defective memory, P. C.

Hamerton says that, so far from writing, as might be expected, a letter

of condolence on a miserable memory, he felt disposed to write a letter

of congratulation. “It is possible that you may be blessed with a

selecting memory which is not only useful for what it retains, but also

for what it rejects. In the immense mass of facts which come before you

in literature and in life it is well that you should suffer as little

bewilderment as possible. The nature of your memory saves you from this

by unconsciously selecting what has interested you and letting the rest

go by.”[27]

[Sidenote: Analytical memory.]

In the last quotation we get a hint of the form of memory which Latham

styles the analytical. “The analytical memory is exercised when the

mind furnishes a view of its own and thereby holds together a set of

impressions selected out of a mass. Thus a barrister strings together the

material facts of his case, and a lecturer those of his science by their

bearing on what he wants to establish.”

Many thinkers sift everything they read, hear, and see. That which they

do not need is rejected and forgotten. That which has a bearing upon

their investigations is selected, retained, and utilized. As an aid in

thinking a form of retention called the index memory is very helpful.

The lawyer should know where to find such law as he does not carry in

his head. Having found the required statute or judicial interpretation,

he applies it to the case in hand. No sooner is a case finally decided

or settled than he drops its details from his mind and directs his

intellectual strength to the interests of the next client.

In this ability to sift, select, and reject, as the occasion demands,

lies the secret of the success of many a public lecturer, of many a

magazine writer. The men in the pulpit or upon the platform who lack

this gift soon wear out; the public speedily detects when they have

nothing more to give. The preparation of debates, speeches, essays, and

theses trains these forms of memory. After the analytical habit has been

formed, the student unconsciously, yet constantly, gathers, classifies,

and stores materials for thought. The public are frequently surprised by

the array of striking facts, interesting data, apt illustrations, and

pleasing anecdotes with which he enlivens every topic of discussion and

elucidates every subject of investigation.

[Sidenote: Assimilative memory.]

Higher than the analytical is the assimilative form of memory which

“absorbs matter into the system so that the knowledge assimilated

becomes a part of the person’s own self, like that of his name or of a

familiar language.” The assimilation of knowledge has a parallel in the

assimilation of food. The phrase that knowledge is the food of the mind

has almost become classical in treatises on education. The figure of

speech throws light upon the relative functions of memory and thinking

in the acquisition and elaboration of knowledge. Before the food is set

before the child it should be cooked and put into the most palatable

form,—a parallel to the preparation of the lesson by the teacher so that

he may put it before the learner in its most attractive form.

Before the food is swallowed it should be masticated, broken into

parts,—a parallel to the act of analysis by which the chunks of knowledge

are resolved into their elements and each set before the mind in the

simplest form, in the form in which it can be grasped most easily.

[Sidenote: Transformation of knowledge.]

If the food remains in the stomach unchanged, it produces dyspepsia and a

long train of bodily ills. If the knowledge which the mind appropriates

is retained unchanged, it produces mental dyspepsia, and there is

no real assimilation. From this point of view we can easily see why

Montaigne said that to know by heart is not to know at all. Just as the

food which is taken into the body must be transformed into chyme and

chyle and blood before it can be assimilated, so the knowledge which is

taken up by the mind must be transformed if it is to be assimilated.

The best illustration of the transformation of knowledge is that given

by an anecdote of Gough, which has now become classic. In a Pullman

car a crying child was disturbing the slumbers of every passenger. At

last a gruff miner, whose patience was exhausted, stuck his head out

of his berth and exclaimed, “I should like to know where that child’s

mother is?” “In the baggage car in a coffin,” was the reply of the

person in charge of the child. The knowledge imparted by that phrase

was immediately transformed into new thought and sentiment and purpose.

There was not another word of complaint throughout the entire journey;

every passenger was thinking of the unfortunate child in the light of an

orphan. Their hearts were stirred with feelings of sympathy, which, in

the case of the old miner, issued into will and purpose, for he got up,

began to carry the little one, and did his best to make it feel contented

in the new surroundings. If the lessons in civil government and history

of the United States remain in the memory a mere tissue of dates, names,

and events, the teacher has failed, no matter how brilliant the answers

in class or at the examination. If these lessons do not issue in new

thoughts, sentiments, and purposes, if they do not enlarge the mental

vision of the pupils, beget in them the sentiment of patriotism and cause

them to resolve that they will support the government by paying a just

share of its taxes and by insisting on a pure ballot,—in a word, if these

lessons do not make the pupil say that he will live for his country and

even die in its defence,—then the teacher has failed because there has

been no adequate assimilation of knowledge.

Another figure of speech is sometimes used to describe the transformation

of knowledge. “Except a grain of wheat fall into the earth and die, it

abideth by itself alone; but if it die, it beareth much fruit.”[28] If

the knowledge which enters the mind remains unchanged, it abideth by

itself alone. But if it perish in its original form, if it is changed

through the process of growth so as to enter into new relations, it

brings forth a harvest of thought and sentiment and purpose. The last two

should be the concomitants of the crop of new thoughts which spring from

seed-thoughts implanted in the soul.

That the ancients understood the use and abuse of the memory is evident

from their method of teaching law.

[Sidenote: Teaching the law.]

The Roman school-boy learned by heart the Twelve Tables of the Law.

His teachers were not satisfied with a mere knowledge of the words;

they insisted that he should understand the meaning of the law, and

apply it in regulating his own conduct and in passing judgment upon the

conduct of others. Is it any wonder that the Roman people became the

exponents of law and order throughout the civilized world, and that Roman

jurisprudence still exerts a moulding influence upon the legislation of

the Latin races, if not of the entire civilized world?

There is still another nation of antiquity whose youth were instructed

in the law with the most scrupulous care. The Ten Commandments of the

Mosaic Law were committed to memory. In Chapter VI., 6-9, of Deuteronomy,

we read: “And these words, which I command thee this day, shall be in

thine heart: and thou shalt teach them diligently unto thy children,

and shalt talk of them when thou sittest in thine house, and when thou

walkest by the way, and when thou liest down, and when thou risest up.

And thou shalt bind them for a sign upon thine hand, and they shall be

as frontlets between thine eyes.” Verse 18 of Chapter XI. is still more

explicit: “Therefore shall ye lay up these my words in your heart and in

your soul, and bind them for a sign upon your hand, that they may be as

frontlets between your eyes.”

The exact words of the law were to be fixed in the memory, and kept both

before the bodily and mental eye until they passed into the deeds and

conduct of every-day life. In John vii. 49 we find the same thought:

“This people who knoweth not the law are cursed.” This was the universal

conviction of the Jewish people after the Babylonian exile, if not

before. The reading of the Talmud has been likened unto travelling

through endless galleries of lumber, where the air is darkened and the

lungs are well-nigh asphyxiated with the rising dust. On one point,

however, the Jewish Rabbis speak with the authority and earnestness of

those who know whereof they affirm. “To the Law!” is the exhortation

sounded abroad in every key. “Let your house,” says one, “be a house of

assembly for those wise in the law; let yourself be dusted by the dust

of their feet, and drink eagerly their teaching.” “Make the study of the

law thy special business,” says another. “The more teaching of the law,”

says a third, “the more life; the more school, the more wisdom; the more

counsel, the more reasonable action. He who gains a knowledge of the law

gains life in the world to come.”

Maxims like the following show the stress that was laid upon exercises

designed to bring out the full force and import of the law: “When two

sit together and do not converse about the law, they are an assembly of

scorners, of which it is said, ‘Sit not in the seat of the scorners.’

When, however, two sit together and converse about the law, the Shechinah

(the Divine Presence) is present among them.” “When three eat together at

one table, and do not converse about the law, it is as though they ate of

the offerings of the dead. But when three eat together at one table and

converse about the law, it is as though they ate at the table of God.”

“The following are things whose interest is enjoyed in this world, while

the capital remains for the world to come; Reverence for fathers and

mothers, benevolence, peacemaking among neighbors, and the study of the

law above them all.”

It is very apparent that the chosen people were not satisfied with

mere memorizing of the law. Their teachers sought to make it a living,

regulative force in all the relations of man. Their practice emphasized

a phase of memory work which should be borne in mind whenever pupils are

requested to learn by heart any form of words or selection of literature.

Words have no value so long as they remain mere words. When words convey

the intended meaning, the more perfect the form in which they are joined

together the deeper and more lasting is the impression made upon the

mind of the learner. The thoughts which have been transmitted in forms

fixed for ages may not produce a harvest of new thought and linguistic

expression, but may issue in feeling and will, in lofty emotions and

noble purposes, in heroic deeds and unselfish devotion, in righteousness

and right conduct far more valuable than mediocre effusions of prose and

poetry, or many of the speculations of scientists and philosophers.
