Now, this first animal soul certainly does not exist; it is nothing more than the movement of our organs. Take heed, O man! lest thou have no more proofs but thy weak reason that the other soul exists. Thou canst not know it but by faith; thou art born, thou eatest, thou thinkest, thou wakest, thou sleepest, without knowing how. God has given thee the faculty of thinking, as He has given thee all the rest; and if He had not come at the time appointed by His providence, to teach thee that thou hast an immaterial and an immortal soul, thou wouldst have no proof whatever of it. Let us examine the fine systems on the soul, which thy philosophy has fabricated. One says that the soul of man is part of the substance of God Himself; another that it is part of the great whole; a third that it is created from all eternity; a fourth that it is made, and not created. Others assure us that God makes souls according as they are wanted, and that they arrive at the moment of copulation. They are lodged in the seminal animalcules, cries one. No, says another, they take up their abode in the Fallopian tubes. A third comes and says: You are all wrong; the soul waits for six weeks, until the fœtus is formed, and then it takes possession of the pineal gland; but if it finds a false conception, it returns and waits for a better opportunity. The last opinion is that its dwelling is in the callous body; this is the post assigned to it by La Peyronie. A man should be first surgeon to the king of France to dispose in this way of the lodging of the soul. Yet the callous body was not so successful in the world as the surgeon was. St. Thomas in his question 75 and following, says that the soul is a form subsisting _per se_, that it is all in all, that its essence differs from its power; that there are three vegetative souls, viz., the nutritive, the argumentative, and the generative; that the memory of spiritual things is spiritual, and the memory of corporeal things is corporeal; that the rational soul is a form "immaterial as to its operations, and material as to its being." St. Thomas wrote two thousand pages, of like force and clearness; and he is the angel of the schools.
