PREFACE

It is hoped that this little work may a.s.sist in the search along the dark path upon which many a poet and--in later times--many an investigator has set his feet. It would not be worthy of us, whom science and technical ability has raised to so high an intellectual position as explorers of Nature in every field--should we neglect anything however trivial, deeming it as beneath our notice.

We know so much about all that lies around us: the manner in which the cells build our bodies; how the juices circulate within the plant. We feel Nature to be ensouled, to be a spiritual ent.i.ty--and yet--it is only her corporeal life with which we are intimate. Therefore let us now turn our eyes to new horizons, so that the human spirit may be in a position to extend its search, doing so with knowledge and understanding. What is imperative is that we should investigate to what degree the higher animals have been dowered with sensibility, and to what extent this can be utilized: whether it can crystallize--so to speak--into what is known to us as _thought_. My own work of investigation was undertaken in a spirit entirely devoid of prejudice; and what I have so far discovered I now place in the hands of the reader, asking him to bring the same unbiased and objective att.i.tude of mind to bear when reading these pages. It is my hope that they may arouse his interest and instil that broader att.i.tude of thought which should lead to further investigation, since a question so serious and important does not permit of being lightly set aside.

I have given a short preliminary account of earlier investigations undertaken in this field of research, before inviting the reader to accompany me along the path I myself pursued into this New Land.

THOUGHT CAPACITY IN ANIMALS

It was in the year 1904 that the first experiments towards understanding an animal's ability to think were brought into public light. Wilhelm von Osten then introduced his stallion Hans II to all who seemed interested in the subject, and the most diametrically opposed opinions were soon rife with regard to the abilities of this horse, to which von Osten maintained he had succeeded in teaching both spelling and arithmetic.

The animal's mental activity was said to lie in a simple form of thinking, called into being and intensified by means of a certain amount of instruction. Von Osten, who had been a schoolmaster, had previously spent some fourteen years in testing the intelligence of two other horses before he ventured to make his experiences public, and the performances of these animals were not only remarkable, but of far-reaching importance.

Hans I, aged twelve, died in 1905. He had never appeared in public, since his abilities had been relatively modest. He had, nevertheless, been able to count up to five, as well as carry out quite a number of verbal instructions. It was Hans II, however, that convinced his master--as early as 1902--of his ability to comprehend a far greater range of the German alphabet (when written), as well as to recognize a certain number of colours.

Instances, denoting signs of evident reflection and memory, had led to Wilhelm von Osten turning his thoughts towards this work of animal tuition. Public opinion was divided; there were some who took the subject seriously and who were grateful to this innovator for thus opening a new path of inquiry; yet many were sceptical--and the scientific commission called together in 1904 to investigate the subject, finally knew no better than to heap their ridicule on the careful and patient labours of a lifetime. "Der kluge Hans" ("wise" or "clever Hans")--by that time already a public character--now evoked supercilious smiles and stood disgraced in the eyes of the majority.

Only a few, capable of delving more deeply into the subject, continued to follow these performances with ever-increasing interest and amazement and kept their faith whole.

Von Osten--though now embittered and pathetically silent--quietly continued his experiments up to his death, which took place in 1909. At first he had gone about his work alone, but he was joined subsequently by Karl Krall, who then became known in connexion with this work for the first time.

Many were the attempts made in certain quarters of the Press to account for the facts of the case; the very simple means of procedure employed by von Osten were scouted and the whole thing proclaimed to be based upon trickery, influence, secret signs, an abnormal degree of training, and what not--anything and everything was seized upon in order to come into line with ordinary opinion.

Then, in the year 1905, Karl Krall, of Elberfeld, began his experiments with Hans II, encouraging, as a foundation for the furtherance of his theories, the abilities already developed in this horse, while devoting a more profound measure of insight to the entire problem.

Karl Krall, who lavished an untold amount of time and money on the question, has also raised it to an immeasurably higher plane. He has, indeed, placed a remarkable collection of carefully selected material at the service of the scientific world. With an unusual amount of devotion, backed by patience and a genuine affection for his charges, Karl Krall has carried on a work of investigation to which he a.s.signs no narrow limits; pursuing his labours with a cheerful energy, fully convinced of the sacredness of his task.

Anyone who has come into contact with Krall must feel respect for this man, whatever doubts he may harbour as to the results obtained.

In 1908 Krall started work with two Arab stallions, Zarif and Mohammed.

Both these animals learnt to count by means of rapping out the numbers with their hoofs on a board. One rap with the left fore-hoof always counted as "ten," while each rap with the right fore-hoof counted as "one" only. The number twenty-five was, therefore, composed of two left raps and five right ones. Spelling was similarly indicated by a system of raps meant to express separate letters of the alphabet. A pause followed after each number and the answers, being displayed to sight in the form of rows of numbers, it sufficed to place the letter thus indicated beneath its respective number in order to work out the reply.

In the course of time these animals learnt the most varied forms of arithmetic, even to the extent of extracting the most difficult roots.

They had, indeed, learnt to give answers which were, for the part, quite independent--thus supplying the most unexpected insight into their actual thinking and feeling.

They also learnt the divisions of time, while every kind of experiment was undertaken in order to test their reasoning capacity. All these attempts and the majority of results were of such a nature that it became quite impossible not to realize that further persistence along the same lines of inquiry was bound to lead to a confirmation of the a.s.surances already given by Karl Krall with regard to his pupils'

"scholars.h.i.+p." Many diverse opinions were heard, while the number of serious adherents to the cause as well as that of its opponents increased. Special instances to which objection had been taken on the score of supposed "influence," or of "signalling," were carefully investigated by Krall in order to clear up any implied doubts. For this purpose a blind horse, by name "Bertho," was taken in hand, proof being thus provided to confute the mythical "code of signals" supposed to exist between master and pupil. Other tests undertaken with Bertho were equally successful; Krall was, in fact, always eager and willing to submit every objection brought forward to investigation, evident though it was, that his own vast experience amply sufficed to tip the balance in his favour.

It would take us too long should we attempt to enter into any detailed discussion on this point. Krall's book, "Denkende Tiere" ("Thinking Animals")[1], may be recommended as the best source for investigation for those desiring to know more on this subject.

It must in any case be admitted that the investigations undertaken by Krall have shed a flood of light on the problem of the capacity for thought latent in our higher animals, enabling him, as we have seen, to lay down--within certain limits--in how far and in what way the existence of this capability can be _proved_ where the horse is concerned. Up to the commencement of the Great War these investigations were continued, a number of different horses being used for the purpose.

In the year 1912 I became acquainted with a new contribution towards the question of animal psychology in the person of a Mannheim dog called "Rolf."

The manner in which Rolf's gifts revealed themselves was disclosed in the columns of the "Muenchner Nachrichten" as follows:

"OUR DOG ROLF

"_By Frau Paula Moekel_ (nee _von Moers, in Mannheim_)

"Anyone possessing an intelligent dog of his own will probably occupy himself far more with it than he is wont to do with other animals. This has been the case with our Rolf, a two-year-old Airedale terrier, which has already attained to celebrity. It was accident that led to our discovery of his talent for doing sums correctly. Our children were sitting together at work on their home-lessons, and one of my little girls--seized with a fit of inattention--was unable to solve her very easy task, viz., 122 plus 2. At length, and after the child had stumbled repeatedly over this simple answer, my patience was at an end, and I punished her. Rolf, whose attachment to the children is quite touching, looked very sad, and he gazed at Frieda with his expressive eyes as though he was anxious to help her. Seeing this I exclaimed: 'Just see what eyes Rolf is making! It looks as if _he_ knew what you do not!' No sooner had I said this than Rolf, who had been lying under my writing-table, got up and came to my side. In surprise I asked him: 'Well, Rolf, do you know what two plus two amounts to?' Whereupon the animal tapped my arm with his paw _four times_--we were all speechless! After a little while we asked him again--'5 plus 5?'

Here, too, the correct answer was forthcoming, and thus on the first day did we question him up to a hundred, and with equal success. After that verbal instruction became my daily occupation with the dog, in the same way that one might teach an intelligent child, Rolf entering readily into everything, indeed, we seemed to notice that his studies gave him pleasure. By degrees he became able to solve his sums correctly in every form of arithmetic, finally even getting as far as to extract two and three roots.

"We soon noticed that Rolf could also recognize letters and numerals. He read his own name easily, for when anyone began to write it on the typewriter he instantly started wagging his tail with delight. Our greatest desire now was to devise some means of communication with him and I therefore began with the following simple explanation:

"'Rolf,' I said, 'if you could say yes and no, you would be able to talk to us; now, look here! when you want to say _yes_, give us your paw _twice_, and if _no_, then give it _three_ times,' and I at once put this suggestion to an easy test, for I asked him if he would like to be spanked--and he returned a decided _no_! Then I asked him if he would like some cake, to which a prompt and joyful affirmative was given. I saw therefore that Rolf understood me, and upon this mutual basis I proceeded carefully to build. At length his alphabet came into being--he having, with the exception of one or two letters, put it together entirely by himself. It was constructed thus: I would ask him, for instance, 'Rolf, how many taps with your paw are you going to give me for _a_?' and he then gave me a number which I carefully noted down. To my inexpressible pleasure I found that Rolf never forgot the numbers he had given, though I, to this day, must have my notes to hand whenever Rolf wishes to tap out anything. It is also remarkable that on a nearer investigation of his "alphabet" it becomes evident that the letters Rolf requires least are made up of the highest numbers, whereas those to which he has constant recourse have their equivalents among the lower numbers. The letters q, v, x, Rolf never uses, as though he wished to prove to me that they are entirely useless and superfluous. Rolf can recognize any money that is shown him and counts the flowers in a bunch according to their colours and varieties. He can also differentiate the high and the deep tones on any instrument, and he is even capable of telling the number of tones struck in a chord. His memory is marvellous; he remembers names and numbers over quite a period of time, once he has heard them, and he is ready to do his tasks with any persons who are sympathetic to him should he know them well enough. It is, however, difficult to get him to work as long as anyone who is not sympathetic remains in the room. What he raps out is, of course, phonetically spelt--just according to how it sounds to him, and we have not attempted to worry him with orthography! His own original remarks are delightful."

The dog, Rolf, attained in the course of time to a higher level than did the horses. This may probably be explained by the fact that dogs are, as a rule, more continuously in the company of human beings, being also due to their superior intelligence. Rolf's mode of procedure consisted in a series of raps given with his fore-paws, similar to those given by the horses with their hoofs; but Rolf used the same paw for both decimals and units, so that we had from time to time to inquire after every number rapped out--'Is it a decimal or a unit?'

Whereupon he would rap 'yes,' or 'no'--as the case might be. The numbers were then written down and the answers thus obtained.

Rolf's feats of arithmetic, like those performed by the horses, included finding the square root in the most difficult problems; yet it was in the matter of spelling answers that he excelled. Indeed, he seemed to command a particularly rich vocabulary, and applied the same with the greatest accuracy and continuity, even in long answers. These replies, when collected in their proper sequence should provide us with a wealth of insight into an animal's life of feeling. Such a collection is already extant, but has not yet been made public.

Many of the dog's answers, as well as innumerable debates about him have been published in the "Mitteilungen der Gesellschaft fur Tierpsychologie"[2] ("Communications of the Society for the Study of Animal Psychology"), while others may be found in the periodical "Animal Soul."[3]

[2] Published by the committee through the agency of Professor Ziegler.

Rolf has made frequent public appearances and been subjected to tests of several hours' duration. These have taken place both in the presence of his kind and gifted mistress and teacher, and also quite alone with his examiners. On every occasion of his appearance notes have been taken as to the procedures, and on one occasion these were even attested by a Notary. At such times, indeed, suggestions were not infrequently made which might be said to exceed every justifiable limit; tests were carried out prior to which the whole family had to vacate the house--carpets were taken up, in order to hunt for electric wires; window-shutters were closed; cupboards and premises searched, and sentinels posted--all this being tolerated by them with the utmost good-humour! And in spite of all this upheaval, Rolf was almost without exception ready with his replies! A fact that may well be set to his credit, when we consider how sensitive and capricious animals are by nature. Of his examiners, it may be said, that they covered themselves with confusion.

One public appearance brought him well-merited praise from a large circle of acquaintances. So excellently did he acquit himself on this occasion that I should like to place it on record.

"REPORT OF THE PUBLIC APPEARANCE OF THE SPELLING DOG ROLF

"_By Professor H. F. Ziegler_

"In order to collect subscriptions for the benefit of the Central Committee of War Charities, as also for the Society responsible for the dogs for Army Medical Service, Frau Dr. Moekel kindly consented to introduce her dog Rolf to the general public for the first time.

"The performance took place in the Hall of the Casino at Mannheim, on the 11th of May, 1914. Every seat in the Hall was taken.

"Professor Kraemer of Hohenheim opened the meeting; he dwelt on the usefulness of these dogs--trained to perform tasks in which their intelligence accounted for no small part. He alluded to the scientific importance of the new method of instruction by means of spelling--a method first brought forward in connexion with the 'Thinking Horses'

belonging to Messrs. von Osten and K. Krall, and which had revealed hitherto unexpected aspects of the animal soul.
