Whoever does not believe in the importance of conducting the examination at the place of an event, needs only to repeat his examination twice, once at the court, and again at the place—then he certainly will doubt no more. Of course the thing should not be so done that the event should be discussed with the witness at the place of its occurrence and then the protocol written in the house of the mayor, or in an inn half an hour away—the protocol must to the very last stroke of the pen be written then and there, in order that every impression may be renewed and every smallest doubt studied and corrected. Then the differences between what has passed, what has been later added, and what is found to-day can be easily determined by sticking to the rule of Uphues, that the recognition of the present as present is always necessary for the eventual recognition of the past. Kant has already suggested what surprising results such an examination will give: “There are many ideas which we shall never again in our lives be conscious of, unless some occasion cause them to spring up in the memory.” But such a particularly powerful occasion is locality, inasmuch as it brings into play all the influences which our senses are capable of responding to.[222]
Of course the possibility of artificially-stimulated memory disappears like all memory, with the lapse of time. As a matter of fact, we know that those of our experiences which concern particular persons and things, and which are recalled at the sight of those persons and things, become, later on, when the connections of images have been broken, capable only of awakening general notions, even though the persons or things are as absolutely present as before. But very unfavorable circumstances must have been at work before such a situation can develop.
It is characteristic, as is popularly known, that memory can be intensified by means of special occasions. It is Höfler’s opinion that the Spartan boys were whipped at the boundary stones of their country in order that they might recall their position, and even now-a-days our peasants have the custom, when setting up new boundary stones, of grasping small boys by the ears and hair in order that they shall the better remember the position of the new boundary mark when, as grown men, they will be questioned about it. This being the case, it is safer to believe a witness when he can demonstrate some intensely influential event which was contemporaneous with the situation under discussion, and which reminds him of that situation.
Section 54. (c) The Peculiarities of Reproduction.
The differences in memory which men exhibit are not, among their other human qualities, the least. As is well known, this difference is expressed not only in the vigor, reliability, and promptness of their memory, but also in the field of memory, in the accompaniment of rapid prehensivity by rapid forgetfulness, or slow prehensivity and slow forgetfulness, or in the contrast between narrow, but intense memory, and broad but approximate memory.
Certain special considerations arise with regard to the field of greatest memory. As a rule, it may be presupposed that a memory which has developed with especial vigor in one direction has generally done this at the cost of memory in another direction. Thus, as a rule, memory for numbers and memory for names exclude each other. My father had so bad a memory for names that very frequently he could not quickly recall my Christian name, and I was his own son. Frequently he had to repeat the names of his four brothers until he hit upon mine, and that was not always a successful way.[223] When he undertook an introduction it was always: “My honored m—m—m,”—“The dear friend of my youth m—m—m.” On the other hand, his memory for figures was astounding. He noted and remembered not only figures that interested him for one reason or another, but also those that had not the slightest connection with him, and that he had read merely by accident. He could recall instantaneously the population of countries and cities, and I remember that once, in the course of an accidental conversation, he mentioned the production of beetroot in a certain country for the last ten years, or the factory number of my watch that he had given me fifteen years before and had never since held in his hand. He often said that the figures he carried in his head troubled him. In this regard the symptom may be mentioned that he was not a good mathematician, but so exceptional a card player that nobody wanted to play with him. He noticed every single card dealt and could immediately calculate what cards each player had, and was able to say at the beginning of the game how many points each must have.
Such various developments are numerous and of importance for us because we frequently are unwilling to believe the witness testifying in a certain field for the reason that his memory in another field had shown itself to be unreliable. Schubert and Drobisch cite examples of this sort of thing, but the observations of moderns, like Charcot and Binet, concerning certain lightning calculators (Inaudi, Diamandi, etc.), confirm the fact that the memory for figures is developed at the expense of other matters. Linné tells that Lapps, who otherwise note nothing whatever, are able to recognize individually each one of their numberless reindeer. Again, the Dutch friend of flowers, Voorhelm, had a memory only for tulips, but this was so great that he could recognize twelve hundred species of tulips merely from the dry bulbs.
These fields seem to be of a remarkably narrow extent. Besides specialists (numismatists, zoologists, botanists, heralds, etc.) who, apart from their stupendous memory for their particular matters, appear to have no memory for other things, there are people who can remember only rhymes, melodies, shapes, forms, titles, modes, service, relationships, etc. V. Volkmar has devoted some space to showing this. He has also called attention to the fact that the semi-idiotic have an astounding memory for certain things. This has been confirmed by other students. One of them, Du Potet,[224] who is perhaps the expert in the popular mind of the Austrian Alps, has made it especially clear. As in all mountainous regions there are a great number of those unfortunate idiots who, when fully developed, are called cretins, and in their milder form are semi-human, but do not possess intelligence enough to earn their own living. Nevertheless, many of them possess astounding memories for certain things. One of them is thoroughly conversant with the weather prophecy in the calendar for the past and the present year, and can cite it for each day. Another knows the day and the history of every saint of the Catholic church. Another knows the boundaries of every estate, and the name, etc., of its owner. Another knows each particular animal in a collective herd of cattle, knows to whom it belongs, etc. Of course not one of these unfortunates can read. Drobisch mentions an idiotic boy, not altogether able to speak, who, through the untiring efforts of a lady, succeeded finally in learning to read. Then after hasty reading of any piece of printed matter, he could reproduce what he had read word for word, even when the book had been one in a foreign and unknown tongue. Another author mentions a cretin who could tell exactly the birthdays and death-days of the inhabitants of his town for a decade.
It is a matter of experience that the semi-idiotic have an excellent memory and can accurately reproduce events which are really impressive or alarming, and which have left effects upon them. Many a thing which normal people have barely noticed, or which they have set aside in their memory and have forgotten, is remembered by the semi-idiotic and reproduced. On the contrary, the latter do not remember things which normal people do, and which in the latter frequently have a disturbing influence on the important point they may be considering. Thus the semi-idiotic may be able to describe important things better than normal people. As a rule, however, they disintegrate what is to be remembered too much, and offer too little to make any effective interpretation possible. If such a person, e.g., is witness of a shooting, he notices the shot only, and gives very brief attention to what precedes, what follows, or what is otherwise contemporary. Until his examination he not only knows nothing about it, but even doubts its occurrence. This is the dangerous element in his testimony. Generally it is right to believe his kind willingly. “Children and fools tell the truth,” what they say bears the test, and so when they deny an event there is a tendency to overlook the fact that they have forgotten a great deal and hence to believe that the event had really not occurred.
Similar experiences are yielded in the case of the memory of children. Children and animals live only in the present, because they have no historically organic ideas in mind. They react directly upon stimuli, without any disturbance of their idea of the past. This is valid, however, only for very small children. At a later age children make good witnesses, and a well-brought-up boy is the best witness in the world. We have only to keep in mind that later events tend in the child’s mind to wipe out earlier ones of the same kind.[225] It used to be said that children and nations think only of the latest events. And that is universally true. Just as children abandon even their most precious toys for the sake of a new one, so they tell only the latest events in their experience. And this is especially the case when there are a great many facts—e.g., repeated mal-treatment or thefts, etc. Children will tell only of the very last, the earlier one may absolutely have disappeared from the memory.
