Having said this much, in order to conciliate or part company with those who have no intention of leaving the _terra firma_ of science, let us return to the case before us, which is all the more disquieting inasmuch as we may consider it a sort of prototype of the tragic and almost diabolical reticence which we find in most premonitions. It is probable that under the mattress there was a stray match which the child discovered and struck; this is the only possible explanation of the catastrophe, for there was no fire burning on that floor of the house. If the mother had turned the mattress, she would have seen the match; and, on the other hand, she would certainly have turned the mattress if she had been told that there was a match underneath it. Why did the voice that urged her to perform the necessary action not add the one word that was capable of ensuring that action? The problem moreover is equally perturbing and perhaps equally insoluble whether it concern our own subconscious faculties, or spirits, or strange intelligences. Those who give these warnings must know that they will be useless, because they manifestly foresee the event as a whole; but they must also know that one last word, which they do not pronounce, would be enough to prevent the misfortune that is already consummated in their prevision. They know it so well that they bring this word to the very edge of the abyss, hold it suspended there, almost let it fall and recapture it suddenly at the moment when its weight would have caused happiness and life to rise once more to the surface of the mighty gulf. What then is this mystery? Is it incapacity or hostility? If they are incapable, what is the unexpected and sovran force that interposes between them and us? And, if they are hostile, on what, on whom are they revenging themselves? What can be the secret of those inhuman games, of those uncanny and cruel diversions on the most slippery and dangerous peaks of fate? Why warn, if they know that the warning will be in vain? Of whom are they making sport? Is there really an inflexible fatality by virtue of which that which has to be accomplished is accomplished from all eternity? But then why not respect silence, since all speech is useless? Or do they, in spite of all, perceive a gleam, a crevice in the inexorable wall? What hope do they find in it? Have they not seen more clearly than ourselves that no deliverance can come through that crevice? One could understand this fluttering and wavering, all these efforts of theirs, if they did not know; but here it is proved that they know everything, since they foretell exactly that which they might prevent. If we press them with questions, they answer that there is nothing to be done, that no human power could avert or thwart the issue. Are they mad, bored, irritable or accessory to a hideous pleasantry? Does our fate depend on the happy solution of some petty enigma or childish conundrum, even as our
