The perception of imminent danger is here, I admit, even more abnormal than in the previous example, but it comes under the same heading. It is a phenomenon of subliminal hypersensitiveness observed more than once, a sort of premonition induced by subconscious perceptions, which has been christened by the barbarous name of "cryptaesthesia." But the interval between the moment when the peril is signalled and that at which it is consummated is too short for those questions which relate to a knowledge or a preexistence of the future to arise in this instance.
The case is almost the same with the adventure of an American dentist, very carefully investigated by Dr. Hodgson. The dentist was bending over a bench on which was a little copper in which he was vulcanizing some rubber, when he heard a voice calling, in a quick and imperative manner, these words:
"Run to the window, quick! Run to the window, quick!"
He at once ran to the window and looked out to the street below, when suddenly he heard a tremendous report and, looking round, saw that the copper had exploded, destroying a great part of the workroom.[1]

Here again, a subconscious cautiousness was probably amused by certain indications imperceptible to our ordinary senses. It is even possible that there exists between things and ourselves a sort of sympathy or subliminal communion which makes us experience the trials and emotions of matter that has reached the limits of its existence, unless, as is more likely, there is merely a simple coincidence between the chance idea of a possible explosion and its realization.
A last and rather more complicated case is that of Jean Dupre, the sculptor, who was driving alone with his wife along a mountain road, skirting a perpendicular cliff. Suddenly they both heard a voice that seemed to come from the mountain crying:
"Stop!"
They turned round, saw nobody and continued their road. But the cries were repeated again and again, without anything to reveal the presence of a human being amid the solitude. At last the sculptor alighted and saw that the left wheel of the carriage, which was grazing the edge of the precipice, had lost its linch-pin and was on the point of leaving the axle-tree, which would almost inevitably have hurled the carriage into the abyss.
Need we, even here, relinquish the theory of subconscious perceptions? Do we know and can the author of the anecdote, whose good faith is not in question, tell us that certain unperceived circumstances, such as the grating of the wheel or the swaying of the carriage, did not give him the first alarm? After all, we know how easily stories of this kind involuntarily take a dramatic turn even at the actual moment and especially afterwards.
These examples--and there are many more of a similar kind--are enough, I think, to illustrate this class of premonitions. The problem in these cases is simpler than when it relates to fruitless warnings; at least it is simpler so long as we do not bring into discussion the question of spirits, of unknown intelligences, or of an actual knowledge of the future; otherwise the same difficulty reappears and the warning, which this time seems efficacious, is in reality just as vain. In fact, the mysterious entity which knows that the traveler will go to the water's edge, that the wheel will be on the point of leaving the axle, that the copper will explode, or that the promontory will fall at a precise moment, must at the same time know that the traveler will not take the last fatal step, that the carriage will not be overturned, that the copper will not hurt anybody and that the canoe will pull away from the promontory. It is inadmissible that, seeing one thing, it will not see the other, since everything happens at the same point, in the course of the same second. Can we say that, if it had not given warning, the little saving movement would not have been executed? How can we imagine a future which, at one and the same time, has parts that are steadfast and others that are not? If it is foreseen that the promontory will fall and that the traveler will escape, thanks to the supernatural warning, it is necessarily foreseen that the warning will be given; and, if so, what is the point of this futile comedy? I see no reasonable explanation of it in the spiritist or spiritualistic theory, which postulates a complete knowledge of the future, at least at a settled point and moment.
On the other hand, if we adhere to the theory of a subliminal consciousness, we find there an explanation which is quite worthy of acceptation. This subliminal consciousness, though, in the majority of cases, it has no clear and comprehensive vision of the immediate future, can nevertheless possess an intuition of imminent danger, thanks to indications that escape our ordinary perception. It can also have a partial, intermittent and so to speak flickering vision of the future event and, if doubtful, can risk giving an incoherent warning, which, for that matter, will change nothing in that which already is.
In conclusion, let us state once more that fruitful premonitions necessarily annihilate events in the bud and consequently work their own destruction, so that any control becomes impossible.
