Space is more familiar to us, because the accidents of our organism place us more directly in relation with it and make it more concrete. We can move in it pretty freely, in a certain number of directions before and behind us. That is why no traveller would take it into his head to maintain that the towns which he has not yet visited will become real only at the moment when he sets his foot within their walls. Yet this is very nearly what we do when we persuade ourselves that an event which has not yet happened does not yet exist.

But I do not intend, in the wake of so many others, to lose myself in the most insoluble of enigmas. Let us say no more about it, except this alone, that Time is a mystery which we have arbitrarily divided into a Past and a Future, in order to try to understand something of it. In itself we may be almost certain that it is but an immense eternal, motionless Present, in which all that takes place and all that will take place takes place immutably, in which To-Morrow, save in the ephemeral mind of man, is indistinguishable from Yesterday or To-Day.
One would say that man had always the feeling that a mere infirmity of his mind separates him from the Future. He knows it to be there, living, actual, perfect, behind a kind of wall around which he has never ceased to turn since the first days of his coming on this earth. Or rather, he feels it within himself and known to a part of himself: only, that importunate and disquieting knowledge is unable to travel, through the too narrow channels of his senses, to his consciousness, which is the only place where knowledge acquires a name, a useful strength and, so to speak, the freedom of the human city. It is only by glimmers, by casual and passing infiltrations that future years of which he is full, of which the imperious realities surround him on every hand, penetrate to his brain. He marvels that an extraordinary accident should have closed almost hermetically to the Future that brain which plunges into it entirely, even as a sealed vessel plunges, without mixing with it, into the depths of a monstrous sea that overwhelms it, entreats it, teases it and caresses it with a thousand billows.
At all times, man has tried to find crannies in that wall, to provoke infiltrations into that vessel, to pierce the partitions that separate his reason, which knows scarcely anything, from his instinct, which knows all, but cannot make use of its knowledge. It seems as though he must have succeeded more than once. There have been visionaries, prophets, sibyls, pythonesses, in whom a distemper, a spontaneously or artificially hypertrophied nervous system permitted unwonted communications to be established between consciousness and unconsciousness, between the life of the individual and that of the species, between man and his hidden god. They have left evidences of this capacity which are as irrefutable as any other historical evidence. On the other hand, as those strange interpreters, those great mysterious hysterics, along whose nerves thus circulated and mingled the Present and the Past, were rare, men discovered, or thought that they discovered, empirical processes to enable them almost mechanically to read the ever-present and irritating riddle of the Future. They flattered themselves that, in this manner, they could consult the unconscious knowledge of things and beasts. Thence came the interpretation of the flight of birds, of the entrails of victims, of the course of the stars, of fire, water, dreams and all the methods of divination that have been handed down to us by the authors of antiquity.

I thought it curious to inquire where this science of the Future stands to-day. It no longer has the splendour nor the hardihood of old. It no longer forms part of the public and religious life of nations. The Present and the Past reveal so many prodigies to us that these suffice to amuse our thirst for marvels. Absorbed as we are in what is or was, we have almost given up asking what might be or will be. However, the old and venerable science, so deeply rooted in man's infallible instinct, is not abandoned. It is no longer practised in broad daylight. It has taken shelter in the darkest corners, in the most vulgar, credulous, ignorant and despised environments. It employs innocent or childish methods; nevertheless, it, too, has in a certain measure evolved, like other things. It neglects the majority of the processes of primitive divination; it has found others, often eccentric, sometimes ludicrous, and has been able to profit by some few discoveries that were by no means intended for it.
I have followed it into its dark retreats. I wished to see it, not in books, but at work, in real life, and among the humble faithful who have confidence in it and who daily apply to it for advice and encouragement. I went to it in good faith: unbelieving, but ready to believe; without prejudice and without a predetermined smile: for, if we must admit no miracle blindly, it is worse blindly to laugh at it; and in every obstinate error there lurks, usually, an excellent truth that awaits the hour of birth.
