There are two processes which we adopt consciously or unconsciously when we try to prophesy. We can seek a period in the past whose conditions resemble as closely as possible those of our day, and presume that the sequel to that period will, save for some minor alterations, be similar. Secondly, we can survey the general course of development in our immediate past, and endeavor to prolong it into the near future. The first is the method the historian; the second that of the scientist. Only the second is open to us now, and this only in a partial sphere.
The search of our future being is but a needless, anxious, and haste to be knowing, sooner than we can, what, without all this solicitude, we shall know a little later.
What we see as death, empty space, or nothingness is only the trough between the crests of this endlessly waving ocean. It is all part of the illusion that there should seem to be something to be gained in the future, and that there is an urgent necessity to go on and on until we get it. Yet just as there is no time but the present, and no one except the all-and-everything, there is never anything to be gained - though the zest of the game is to pretend that there is.
No rocket will reach the moon save by a miraculous discovery of an explosive far more energetic than any known. And even if the requisite fuel were produced, it would still have to be shown that the rocket machine would operate at 459 degrees below zero-the temperature of interplanetary space.
PAST, n. That part of Eternity with some small fraction of which we have a slight and regrettable acquaintance... The Past is the Future of yesterday, the Future is the Past of to-morrow. They are one - the knowledge and the dream.
