It is precisely the attitude of respectable scientific circles which appears to me a mistake, demanding rectification. I understand perfectly and excuse this attitude. For so many incorrect things have been affirmed, so many ridiculous practices have been recommended by the leaders of the occult movement, that official representatives of science must have felt indignant. Unfortunately no one except Richet has ventured to do for the phenomena vouched for by occultists and spiritists, what Charcot has done for the magnetisers’ allegations. No doubt, this other Charcot will come when the time is ripe. The preparatory work will have been done, and he need only resume the experiments of Richet, Crookes, Lodge, Rochas, Ochorowicz, and many others. I class myself with these experimenters. Many of them are my friends, and, if our manner of thinking be not quite the same, my ideas upon the method to be used are much the same as theirs. And thus I find myself quite naturally led to say what my ideas are. I believe in the reality of certain phenomena which I have been able to verify over and over again. I see no need to attribute these phenomena to any supernatural intervention. I am inclined to think that they are produced by some force existing within ourselves. I believe also that these facts can be subjected to scientific observation. I say observation and not experimentation, because I do not think that it is yet possible to proceed on veritable experimental lines. In order to experiment one must understand the conditions necessary to produce a given result; now, in our case, we have a most imperfect knowledge of the required conditions, which are, nevertheless, necessary antecedents to the sought-for phenomena. We are in the position of the astronomer who can put his eye to the telescope and observe the firmament, but who cannot provoke the production of a single celestial phenomenon. My position is therefore very simple. It is that of an impartial observer. The occult sciences and spiritism never aroused my curiosity, and I was more than thirty years of age, when my attention was drawn towards psychical phenomena. I did not even try to turn a table before I was thirty-five, considering such facts as unworthy of serious examination. It is only since 1892 that I have become interested in these researches. I cannot remember to-day how I was led to take up the study; it was not abruptly. I am certain that no striking incident was ever responsible for a sudden changing of my mind. As far as my recollection goes, I think it was the chance perusal of some theosophical works, which made me curious to know the extent of a mystical movement, whose existence I had not even suspected. My discoveries astonished me, for I never thought that mysticism could find adherents at the end of the nineteenth century. The opening address pronounced by me at the Court of Appeal at Limoges in 1893 was upon this subject.
