It is obviously difficult for us to understand that the future can thus precede chaos, that the present is at the same time the future and the past, or that that which does not yet exists already at the same time at which it is no more. But, on the other hand, it is just as hard to conceive that the future does not preexist, that there is nothing before the present and that everything is only present or past. It is very probable that, to a more universal intelligence than ours, everything is but an eternal present, an immense punctum stans, as the metaphysicians say, in which all the events are on one plane; but it is no less probable that we ourselves, so long as we are men, in order to understand anything of this eternal present, will always be obliged to divide it into three parts. Thus caught between two mysteries equally baffling to our intelligence, whether we deny or admit the preexistence of the future, we are really only wrangling over words: in the one case, we give the name of "present," from the point of view of a perfect intelligence, to that which to us is the future; in the other, we give the name of "future" to that which, from the point of view of a perfect intelligence, is the present. But, after all, it is incontestable in both cases that, at least from our point of view, the future preexists, since preexistence is the only name by which we can describe and the only form under which we can conceive that which we do not yet see in the present. 28 Attempts have been made to shed light on the riddle by transferring it to space. It is true that it there loses the greater part of its obscurity; but this apparently is because, in changing its environment, it has completely changed its nature and no longer bears any relation to what it was when it was placed in time. We are told, for instance, that innumerable cities distributed over the surface of the earth are to us as if they were not, so long as we have not seen them, and only begin to exist on the day when we visit them. That is true; but space, outside all metaphysical speculations, has realities for us which time does not possess. Space, although very mysterious and incomprehensible once we pass certain limits, is nevertheless not, like time, incomprehensible and illusory in all its parts. We are certainly quite able to conceive that those towns which we have never seen and doubtless never will see indubitably exist, whereas we find it much more difficult to imagine that the catastrophe which, fifty years hence, will annihilate one of them already exists as really as the town itself. We are capable of picturing a spot whence, with keener eyes than these which we boast to-day, we should see in one glance all the cities of the earth and even those of other worlds, but it is much less easy for us to imagine a point in the ages whence we should simultaneously discover the past, the present and the future because the past, the present and the future are three orders of
