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. This "rapport" is that of a master to a child; but to a very special kind of child, a "child" moreover who, from the biological point of view, has not been corrupted by the thousands of years of reasoning and society that weigh on the human child. It is, therefore, nearer to the "fountains of life" if I may be allowed to express myself in that way; and nearer to the mathematical potentiality (which was at first unself-conscious, but which has subsequently been developed). But, of course, it is not enough for mathematics "to be" in something, for that something to begin at once to tap numbers. The table of the mediumistic seances contains much mathematics (in its physical assemblage), but in order to make it "tap" there must be somebody to move it: in fact, a "medium." In my view, as soon as the animal subject has been able to understand "numbers"--and this postulate of the new zoopsychology, I repeat, I believe to be indispensable to the whole edifice--the animal finds itself sufficiently in harmony with the master to become capable (in principle) of all the subsequent "wonders."
