Krall admits the possibility of telepathy (but in a very limited measure): and then, if I remember right, he was looking finally for an explanation which to-day I should perhaps call of the mediumistic type, if I had been better acquainted with it; but in fact I had of him, in his lifetime, only some vague hint on the point.
As to Miss Kindermann, she recognises the possibility of transmission of thought in certain cases (e.g. when Lola is tired or is unwilling to "work" any more). According to her it would be a question of a line of least resistance, along which the "work" of the animal becomes more easy. Hence arises the necessity, as she maintains, for the investigator to be very careful of the danger of falsified results and to abstain with this object from any intentional thought. But these are the very conditions which "mediums" impose on investigators, and if these conditions are not observed, mediumistic séances seem only to be successful with difficulty. Therefore, in trying to resist the danger of telepathic falsification, and without indeed being aware of the resulting consequences, Lola's mistress may have contributed to create the very conditions most favourable to the development of mediumistic action.
V. THE HYPOTHESIS OF CONCOMITANT PSYCHICAL AUTOMATISM
In various parts of her book Miss Kindermann emphasizes the fact that after having given for some days "communications" of a certain kind, a sort of tiredness or annoyance, that gets hold of Lola, completely prevents the repetition of similar communications; but that repetition can take place if some weeks of rest are allowed in the subject which has provoked the tiredness.
In another place she mentions that, with the progress of Lola's "education," the dog's attitude towards herself, and other persons generally, became harder and more difficult, almost hostile (a fact which I find confirmed by certain answers of Lola's referred to elsewhere); just as if the canine consciousness as it gained illumination began to understand the many wrongs done to it by man, which formerly it knew nothing about.
Other observers have repeatedly stated that a capital fact in the story of "thinking" animals is the necessity, which they regard as proved, of a progressive "education" directed at getting from the animal results proportionate to the instruction received.
All these observations and several others of a similar nature would seem to be arguments in favour of a presumed "intelligence" rather than of an automatism in the animal. But they should be accepted cum grano. They may indeed contain a good dose of involuntary suggestion, active or passive. And again, it seems to me, for instance, a very doubtful procedure to maintain, after a positive result has been achieved by the animal, that the result should have been on the other hand negative, if the education has not yet reached the corresponding stage of development; and vice versa. As for me, when I read what Miss Kindermann writes about the rapidity of Lola's progress, I cannot help thinking that, if the authoress had believed that she was able to obtain at once from the dog the results which she did obtain after a year's work, she would have obtained them fully and completely.
But this extreme supposition may be exaggerated. I have already repeatedly referred to the hypothesis that the psychic automatism in question may be only concomitant. That is, I am convinced from what I have seen myself and read that a foundation of intelligence, of logical reasoning and of self consciousness, must go to constitute in the animal the substratum on which the wonders of the "new zoopsychology" are built up.
At first I was rather inclined to believe (as so many others) that the facts discovered at Elberfeld and at Mannheim could and should be explained simply by the recognition of "intelligence" in the animal. The chief results obtained up to then (i.e. up to the date of my last publications on the subject), were the mathematical prodigies performed by Krall's horses, and the first "philosophic" manifestations of Rolf. I accordingly thought that I should be able to interpret the new (and, in its complexity, rather modest) canine "knowledge" by the animal's memory of words which it had heard. But since then the educators have taken pleasure in raising the whole level of these wonders. Rolf's "philosophy" was developed; and in the end they went so far as to make him compose poetry, as I have already had occasion to mention. Then came the performances of Lola. And at this point I, too, must say: "Too much, too much!" At least, as far as concerns the hypothesis of intelligence in the animal.
I understand perfectly that just on account of that "too much," people may be tempted to throw up the whole thing. But as far as I am concerned, I repeat that I do not consider myself justified in doing so. I do not forget the possible intervention of active or passive suggestion: I referred to this a short time ago. But a great abuse is often made of this explanation. In practice "suggestion" explains but little to any one who wants to get to the bottom of things. Neither does it explain the bulk of the facts of the "new zoopsychology." Neither do I forget that in this field also (as in every field of psychological experiments) there may be an interfering although subconscious misuse of spurious factors, such as signs (not intentional or perceptible) by the experimenter to the subject experimented with; a certain amount of falsification in interpretation of results on the part of the experimenters, etc.... But the irreducible residue of the facts is, in my opinion, still enormous as compared with the little that could perhaps be eliminated by these means from the discussion. Therefore, in the absence of anything better for the moment, and subject to further information, I hold to the hypothesis of a psychic automatism of the mediumistic type, as a concomitant phenomenon developed from the normal "rapport" which is necessary and pre-existent.
