The Materialists and the Evolutionists of the Darwinian school would be ill‐advised to accept the newly worked‐out theories of Professor Weissmann, the author of _Beiträge zur Descendenzlehre_, with regard to one of the two mysteries of Embryology, as above specified, which he seems to think he has solved; for, when it is fully solved, Science will have stepped into the domain of the truly Occult, and passed for ever out of the realm of transformation, as taught by Darwin. The two theories are irreconcilable, from the standpoint of Materialism. Regarded from that of the Occultists, however, the new theory solves all these mysteries. Those who are not acquainted with the discovery of Professor Weissmann—at one time a fervent Darwinist—ought to hasten to repair the deficiency. The German embryologist‐philosopher—stepping over the heads of the Greek Hippocrates and Aristotle, right back into the teachings of the old Âryans—shows one infinitesimal cell, out of millions of others at work in the formation of an organism, alone and unaided determining, by means of constant segmentation and multiplication, the correct image of the future man, or animal, in its physical, mental and psychic characteristics. It is this cell which impresses on the face and form of the new individual the features of the parents, or of some distant ancestor; it is this cell, again, which transmits to him the intellectual and mental idiosyncracies of his sires, and so on. This Plasm is the immortal portion of our bodies, developing by means of a process of successive assimilations. Darwin’s theory, viewing the embryological cell as the essence or extract from all other cells, is set aside; it is incapable of accounting for hereditary transmission. There are but two ways of explaining the mystery of heredity: either the substance of the germinal cell is endowed with the faculty of crossing the whole cycle of transformations that lead to the construction of a separate organism, and then to the reproduction of identical germinal cells; or, _these germinal cells do not have their genesis at all in the body of the individual, but proceed directly from the ancestral germinal cell passed from father to son through long generations_. It is the latter hypothesis that Weissmann has adopted and worked upon, and it is to this cell that he traces the immortal portion of man. So far, so good; and when this almost correct theory is accepted, how will Biologists explain the first appearance of this everlasting cell? Unless man “grew” like the immortal “Topsy,” and was not born at all, but fell from the clouds, how was that embryological cell generated in him? Complete the Physical Plasm, mentioned above, the “Germinal Cell” of man with all its material potentialities, with the “Spiritual Plasm,” so to say, or the fluid that contains the five lower principles of the Six‐ principled Dhyâni—and you have the secret, if you are spiritual enough to understand it. Now to the promised simile.
