Once more, I know that, in these cases, as I have seen for myself, the really convincing facts are necessarily very rare; indeed, no elsewhere do we meet with the same difficulty. If the medium tells you, for instance, as Mme. M⸺ seems easily to do, how you will employ your day from the morning onwards, if she sees you in a certain house in a certain street meeting this or that person, it is impossible to say that, on the one hand, she is not already reading your as yet unconscious plans or intentions, or that, on the other hand, by doing what she has foreseen, you are not obeying a suggestion against which you could not fight except by violently doing the opposite to what it demands of you, which again would be a case of inverted suggestion. None therefore would have any value save predictions of unlikely happenings, clearly defined and outside the sphere of the person interested. As Dr. Osty says: “The ideal prognostication would obviously be that of an event so rare, so sudden and unexpected, implying such a change in one’s mode of life that the theory of coincidence could not decently be put forward. But, as everybody is not, in the peaceful course of his existence, threatened by such an absolutely convincing event, the clairvoyant cannot always reveal to the person experimenting—and reveal for a more or less approximate date—one of those incidents whose accomplishment would carry irresistible conviction.” In any case, the question of psychometric prognostications calls for further enquiry, though it is easy even at the present day to foresee the results. 10
