When any discovery or invention is completed, we are frequently astonished at its obvious simplicity. The ideas necessary to the discovery, are seldom so numerous as to fatigue our memory. Memory seems to have been useful to inventors only as it presented a few ideas in a certain happy connection, as it presented them faithfully and distinctly to view in the proper moment. If we wish for examples of the conduct of the understanding, we need only look into Dr. Franklin’s works. He is so free from all affectation, he lays his mind so fairly before us, that he is, perhaps, the best example we can select. Those who are used to look at objects in a microscope, say, that full as much depends upon the object’s being well prepared for inspection, as upon the attention of the observer, or the excellence of the glass.
The first thing that strikes us, in looking over Doctor Franklin’s works, is the variety of his observations upon different subjects. We might imagine, that a very tenacious and powerful memory was necessary to register all these; but Dr. Franklin informs us, that it was his constant practice to note down every hint as it occurred to him: he urges his friends to do the same; he observes, that there is scarcely a day passes without our hearing or seeing something which, if properly attended to, might lead to useful discoveries. By thus committing his ideas to writing, his mind was left at liberty to think. No extraordinary effort of memory was, even upon the greatest occasions, requisite. A friend wrote to him to inquire how he was led to his great discovery of the identity of lightning and electricity; and how he first came to think of drawing down lightning from the clouds. Dr. Franklin replies, that he could not answer better than by giving an extract from the minutes he used to keep of the experiments he made, with memorandums of such as he purposed to make, the reasons for making them, and the observations that rose upon them. By this extract, says Dr. Franklin, you will see that the thought was not so much an out of the way one, but that it might have occurred to any electrician.
When the ideas are arranged in clear order, as we see them in this note, the analogy or induction to which Dr. Franklin was led, appears easy. Why, then, had it never been made by any other person? Numbers of ingenious men were at this time intent upon electricity. The ideas which were necessary to this discovery, were not numerous or complicated. We may remark, that one analogy connecting these observations together, they are more easily recollected; and their being written down for a particular purpose, on which Dr. Franklin’s mind was intent, must have made it still easier to him to retain them.
The degree of memory he was forced to employ, is thus reduced to a portion in which few people are defective. Now, let us suppose, that Dr. Franklin, at the time he wrote his memorandum, had fully in his recollection every previous experiment that had ever been tried on electricity; and not only these, but the theories, names, ages, and private history, of all the men who had tried these experiments; of what advantage would this have been to him? He must have excluded all these impertinent ideas successively as they rose before him, and he must have selected the fifteen useful observations, which we have mentioned, from this troublesome multitude. The chance in such a selection would have been against him; the time employed in the examination and rejection of all the unnecessary recollections, would have been absolutely wasted.
We must wish that it were in our power, when we make observations upon nature, or when we read the reflections of others, to arrange our thoughts so as to be ready when we want to reason or invent. When cards are dealt to us, we can sort our hand according to the known probabilities of the game, and a new arrangement is easily made when we hear what is trumps.
In collecting and sorting observations, Dr. Franklin particularly excelled; therefore we may safely continue to take him for our example. Wherever he happened to be, in a boat, in a mine, in a printer’s shop, in a crowded city, or in the country, in Europe or America, he displays the same activity of observation. When any thing, however trifling, struck him which he could not account for, he never rested till he had traced the effect to its cause. Thus, after having made one remark, he had fresh motive to collect facts, either to confirm or refute an hypothesis; his observations tending consequently to some determinate purpose, they were arranged in the moment they were made, in the most commodious manner, both for his memory and invention; they were arranged either according to their obvious analogies, or their relation to each other as cause and effect. He had two useful methods of judging of the value of his own ideas; he either considered how they could be immediately applied to practical improvements in the arts, or how they could lead to the solution of any of the great problems in science. Here we must again observe, that judgment saved the labour of memory. A person, who sets about to collect facts at random, is little better than a magpie, who picks up and lays by any odd bits of money he can light upon, without knowing their use.
Miscellaneous observations, which are made by those who have no philosophy, may accidentally lead to something useful; but here we admire the good fortune, and not the genius, of the individuals who make such discoveries: these are prizes drawn from the lottery of science, which ought not to seduce us from the paths of sober industry. How long may an observation, fortunately made, continue to be useless to mankind, merely because it has not been reasoned upon! The trifling observation, that a straight stick appears bent in water, was made many hundred years before the reason of that appearance was discovered! The invention of the telescope might have been made by any person who could have pursued this slight observation through all its consequences.
Having now defined, or rather described, what we mean by a good memory, we may consider how the memory should be cultivated. In children, as well as in men, the strength of that habit, or perhaps of that power of the mind which associates ideas together, varies considerably. It is probable, that this difference may depend sometimes upon organization. A child who is born with any defect in his eyes, cannot possibly have the same pleasure in objects of sight, which those enjoy who have strong eyes: ideas associated with these external objects, are, therefore, not associated with pleasure, and, consequently, they are not recollected with any sensations of pleasure. An ingenious writer supposes, that all the difference of capacity amongst men ultimately depends on their original power of feeling pleasure or pain, and their consequent different habits of attention.
When there is any defect in a child’s organization, we must have recourse to physics, and not to metaphysics; but even among children, who are apparently in the full possession of all their senses, we see very different degrees of vivacity: those who have most vivacity, seldom take delight in repeating their ideas; they are more pleased with novelty than prone to habit. Those children who are deficient in vivacity, are much disposed to the easy indolent pleasure of repetition; it costs them less exertion to say or do the same thing over again, than to attempt any thing new; they are uniformly good subjects to habit, because novelty has no charms to seduce their attention.
The education of the memory in these two classes of children, ought not to be the same. Those who are disposed to repetition, should not be indulged in it, because it will increase their indolence; they should be excited by praise, by example, by sympathy, and by all the strongest motives that we can employ. Their interest in every thing around them must by all means be increased: when they show eagerness about any thing, no matter what it is, we may then exercise their memory upon that subject with some hopes of success. It is of importance that they should succeed in their first trials, otherwise they will be discouraged from repeating their attempts, and they will distrust their own memory in future. The fear of not remembering, will occupy, and agitate, and weaken their minds; they should, therefore, be animated by hope. If they fail, at all events let them not be reproached; the mortification they naturally feel, is sufficient: nor should they be left to dwell upon their disappointment; they should have a fresh and easier trial given to them, that they may recover their own self-complacency as expeditiously as possible. It may be said, that there are children of
such a sluggish temperament, that they feel no pleasure in success, and no mortification in perceiving their own mental deficiencies. There are few children of this description; scarcely any, perhaps, whose defects have not been increased by education. Exertion has been made so painful to them, that at length they have sunk into apathy, or submitted in despair to the eternal punishment of shame.
The mistaken notion, that the memory must be exercised only in books, has been often fatal to the pupils of literary people. We remember best those things which interest us most; which are useful to us in conversation; in our daily business or amusement. So do children. On these things we should exercise their memory. Tell a boy who has lost his top, to remember at such a particular time to put you in mind of it, and if he does, that you will give him another, he will probably remember your requests after this, better than you will yourself. Affectionate children will easily extend their recollective memories in the service of their friends and companions. “Put me in mind to give your friend what he asked for, and I will give it to him if you remember it at the right time.” It will be best to manage these affairs so that convenience, and not caprice, shall appear to be your motive for the requests. The time and place should be precisely fixed, and something should be chosen which is likely to recall your request at the appointed time. If you say, put me in mind of such a thing the moment the cloth is taken away after dinner; or as soon as candles are brought into the room; or when I go by such a shop in our walk this evening; here are things mentioned which will much assist the young remembrancer: the moment the cloth is taken away, or the candles come, he will recollect, from association, that something is to be done, that he has something to do; and presently he will make out what that something is.
A good memory for business depends upon local, well arranged associations. The man of business makes an artificial memory for himself out of the trivial occurrences of the day, and the hours as they pass recall their respective occupations. Children can acquire these habits very early in their education; they are eager to give their companions an account of any thing they have seen or heard; their tutors should become their companions, and encourage them by sympathy to address these narrations to them. Children who forget their lessons in chronology, and their pence tables, can relate with perfect accuracy any circumstances which have interested themselves. This shows that there is no deficiency in their capacity. Every one, who has had any experience of the pleasure of talking, knows how intimately it is connected with the pleasure of being listened to. The auditors, consequently, possess supreme power over narrative childhood, without using any artifice, by simply showing attention to well arranged, and well recollected narratives, and ceasing to attend when the young orator’s memory and story become confused, he will naturally be excited to arrange his ideas. The order of time is the first and easiest principle of association to help the memory. This, till young people acquire the ideas of cause and effect, will be their favourite mode of arrangement. Things that happen at the same time; things that are said, thoughts that have occurred, at the same time, will recur to the mind together. We may observe, that ill educated people continue through life to remember things by this single association; and, consequently, there is a heterogeneous collection of ideas in their mind, which have no rational connection with each other; crowds which have accidentally met, and are forced to live for ever together.
A vulgar evidence, when he is examined about his memory of a particular fact, gives as a reason for his remembering it, a relation of a number of other circumstances, which he tells you happened at the same time; or he calls to witness any animate or inanimate objects, which he happened to see at the same time. All these things are so joined with the principal fact in his mind, that his remembering them distinctly, seems to him, and he expects will seem to others, demonstration of the truth and accuracy of his principal assertion. When a lawyer tells him he has nothing to do with these ideas, he is immediately at a stand in his narrative; he can recollect nothing, he is sure of nothing; he has no reason to give for his belief, unless he may say that it was Michaelmas-day when such a thing happened, that he had a goose for dinner that day, or that he had a new wig. Those who have more enlarged minds, seldom produce these strange reasons for remembering facts. Indeed, no one can reason clearly, whose memory has these foolish habits; the ill matched ideas are inseparably joined, and hence they imagine there is some natural connection between them. Hence arise those obstinate prejudices which no arguments can vanquish.
To prevent children from arguing ill, we must, therefore, take care, in exercising their memory, to discourage them in this method of proving that they remember one thing by telling us a number of others which happened at the same time; rather let them be excited to bring their reasoning faculty into play in support of their memory. Suppose, for instance, that a child had mislaid his hat, and was trying to recollect where he had put it. He first may recollect, from the association of time, that he had the hat the last time he went out; but when he wants to recollect when that time was, he had better go back, if he can, to his motive for going out; this one idea will bring a number of others in right order into his mind. He went out, suppose, to fetch his kite, which he was afraid would be wet by a shower of rain; then the boy recollects that his hat must have been wet by the same rain, and that when he came in, instead of hanging it up in its usual place, it was put before the fire to be dried. What fire, is the next question, &c.
Such an instance as this may appear very trivial; but children whose minds are well managed about trifles, will retain good habits when they are to think about matters of consequence. By exercising the memory in this manner about things, instead of about books and lessons, we shall not disgust and tire our pupils, nor shall we give the false notion, that all knowledge is acquired by reading.
Long before children read fluently for their own amusement, they like to hear others read aloud to them, because they have then the entertainment without the labour. We may exercise their memory by asking for an account of what they have heard. But let them never be required to repeat in the words of the book, or even to preserve the same arrangement; let them speak in words of their own, and arrange their ideas to their own plan; this will exercise at once their judgment, invention, and memory.
“Try if you can explain to me what I have just been explaining to you,” a sensible tutor will frequently say to his pupils; and he will suffer them to explain in a different manner from himself; he will only require them to remember what is essential to the explanation. In such repetitions as these, the mind is active, therefore it will strengthen and improve.
Children are all, more or less, pleased with the perception of resemblances and of analogy. This propensity assists us much in the cultivation of the memory; but it must be managed with discretion, or it will injure the other powers of the understanding. There is, in some minds, a futile love of tracing analogies, which leads to superstition, to false reasoning, and false taste. The quick perception of resemblances is, in other minds, productive of wit, poetic genius, and scientific invention. The difference between these two classes, depends upon this — the one has more judgment, and more the habit of using it, than the other. Children who are pleased by trifling coincidences, by allusions, and similitudes, should be taught with great care to reason: when once they perceive the pleasure of demonstration, they will not be contented with the inaccuracy of common analogies. A tutor is often tempted to teach pupils, who are fond of allusions, by means of them, because he finds that they remember well whatever suits their taste for resemblances. By following the real analogies between different arts and sciences, and making use of the knowledge children have on one subject to illustrate another, we may at once amuse their fancy, and cultivate their memory with advantage. Ideas laid up in this manner, will recur in the same order, and will be ready for further use. When two ideas are remembered by their mutual connection, surely it is best that they should both of them be substantially useful; and not that one shou
ld attend merely to answer for the appearance of the other.
As men readily remember those things which are every day useful to them in business, what relates to their amusements, or to their favourite tastes in arts, sciences, or in literature; so children find no difficulty in remembering every thing which mixes daily with their little pleasures. They value knowledge, which is useful and agreeable to them, as highly as we do; but they consider only the present, and we take the future into our estimate. Children feel no interest in half the things that are committed, with the most solemn recommendations, to the care of their memory. It is in vain to tell them, “You must remember such a thing, because it will be useful to you when you grow up to be a man.” The child feels like a child, and has no idea of what he may feel when he grows up to be a man. He tries to remember what he is desired, perhaps, because he wishes to please his wiser friends; but if the ideas are remote from his every day business, if nothing recall them but voluntary exertion, and if he be obliged to abstract his little soul from every thing it holds dear, before he can recollect his lessons, they will have no hold upon his memory; he will feel that recollection is too operose, and he will enjoy none of the “pleasures of memory.”
