Here again, a subconscious cautiousness was probably aroused 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 Dupré, 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, and 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. 21
