Dr. Jaworski, then, undertakes to demonstrate that the human body unites in itself, in a plainly recognizable form, all the living creatures which now exist upon earth and which have existed since the origin of life. In other words, each creature sums up in itself all those which have preceded it; and man, the last-comer, contains within himself the whole biological tree, so much so that, if we could distribute his body, if we could segregate each of his organs and keep it alive in isolation, we should be able to reconstitute all existing forms, to repeople the earth with all the species which it has borne, from the primitive protoplasm to the synthesis, the final achievement, which is man.
We might perhaps go farther than Dr. Jaworski and declare, with the occultists of the east, that we likewise contain within us, in the germ or in a rough-hewn state, all the creatures and all the forms that will come after us. But here we should be leaving the domain of science proper to lose ourselves in a speculation which by its very nature is incapable of verification.
