The earth is not unlike the human brain, in that it contains in itself certain memories of the past: and, just as we rummage out and hunt up in our brains old memories, so do the historian and the antiquary search about in the earth for that memory which it retains of those distant but glorious ages. But the universe, no less than the individual, has another memory besides the material one, and we have endeavoured (Art. 196) to convince our readers that nothing is really lost, the past being always present in the universe. If this be the case, it may readily be conceived that this universal memory may by some process of exaltation and intensification, or as it were by some relay battery of the universe, be occasionally quickened into such a life that the individual in the future and glorified state may be enabled (through the power of the Lord) to realise scenes that happened in the far distant past. For if so much can be accomplished with a thing so little plastic as the material memory of the earth, what may not be done with that infinitely more plastic form of existence which we term the world to come? 257. Again, if in this present world we have great difficulty in realising our own past, we have even greater difficulty in realising what is at this very moment taking place in remote parts of the present visible universe. Astronomers and Physicists agree that life is possible in the planet Mars, and it is quite likely that intelligent beings analogous to ourselves exist at the present moment on the surface of that planet, but we shall never in this life know for certain anything about them. There is an insurmountable barrier to physical inquiry as great as if Mars belonged to the unseen universe, instead of being, what he is in reality, our next-door neighbour in the present. Now, may not this barrier be removed in the future state? This has been a favourite topic with scientific theologians, and we believe that all who have speculated on the conditions of a future life have unanimously agreed that we shall have much greater freedom of motion in the world to come. There can be no doubt that our relations to time and space will then be greatly altered and enlarged. Men shall run to and fro in the universe, and knowledge shall be increased.
