If a worm be supposed to have memory (and worms no doubt have memory in some degree), then it might well be supposed that, if divided in two, each of the parts would inherit the said memory complete. But from that moment the experiences of the two portions, moving in different directions, would bifurcate, and the future stores of memory would be different. Thus we should have a bifurcation of the stream of memory, and a bifurcation of personality—until ultimately, as time went on, and the common memory faded into the background, the two new personalities would begin to feel themselves almost quite separate. Is not this again something like what may have happened to ourselves from Creation’s birth? The stream of life has bifurcated and bifurcated till we have lost our common memory and have become convinced of the absolute separation of our personalities one from the other. On the other hand, the conjunction and fusion of two streams of memory in one is as probable and intelligible as the bifurcation of one into two. Two protozoa fuse; but the race-self in one is the same as in the other, and in reality the process is only a fusion of organic memories and experiences. A man who had been in the habit of changing every year from his Town to his Country house might some day find it convenient to combine his establishments in one suburban residence. Certainly if he had so far forgot _himself_ that in changing houses he had always _quite_ changed his memories, then it would seem impossible to him to combine the two lives in one. Otherwise there would be no difficulty in the process. The stores of one establishment, with their associations and memories would after a time (and not without some maturation-divisions and extrusions!) be got into relation with the stores of the other establishment; and the two bodies of memory and association would settle down together. * * * * *
