Thus difficulties vanish, and problems are solved: thus uncertainty vanishes away, and mysteries which no doctrine, no religion, no philosophy, could dissipate, and which almost made us doubt the justice of God, are cleared up. The doctrine of re-incarnations and prior existences explains everything, answers everything.
We pass on to one of the most interesting questions of the doctrine of the pre-existence of souls, the question of children who have died in infancy. What becomes of children who die at a few days old, or at the age of eight or ten months, or at their birth? Until after all these periods the human soul remains quite undeveloped; it is in almost the same rudimentary state as at the hour of its birth. What, then, is the fate of young children after their death? The doctrine of the plurality of existences simplifies this question. It admits that when an infant dies before it has lived one year (the period of dentition), its soul remains upon the earth, and does not pass, like that of a grown man, into the state of a superhuman being. The soul of an infant a year old is still in a rudimentary condition, almost as much so as at the moment of its birth. The soul of a child who dies at that age has to begin life over again, disengaging itself from the little corpse, it incarnates itself in another newly-born body, and after this fresh incarnation, it begins a second life.
If the new incarnation does not last more than a year, there is no reason why the soul should not undergo a third incarnation in the body of a child, and so on until it shall have accomplished the period of admission to the conditions common to all.
It is impossible that the soul of a child, which is as yet undeveloped, which has added nothing to that which it has received, should be treated as perfected souls, purified by the experience of life, by physical and moral sufferings, who have used their sojourn upon earth as a period of preparation and training. An infant child cannot therefore be admitted to the super-terrestrial dwellings, he simply recommences an interrupted trial. The mortality of children between the day of their birth and the age of one year is so considerable, that nature must have reserved to herself the means of annulling this cause of disarrangement in the sequence and order of her operations.
This explanation of the destiny of young children is conformable to the economy which is observed in the operations of nature. Nature wills that nothing which is created should be lost. The soul of a criminal is evil, but it is a soul, it exists, and it is eternal: it must not be lost. But it must be corrected and perfected, which is done by means of the new existences to which nature consigns that imperfect soul, in order that it may enjoy the means of restoration. Thus the principle of the soul is preserved, and nothing is lost of that which was created. The soul of the child dying in infancy must not be lost either. A second incarnation in another child will permit it to resume the course of its evolution, accidentally interrupted by death. Thus the soul will be preserved, and nothing will be lost.
Chemistry, since Lavoisier's time, has brought to light a great truth: it is, that nothing of the elements of matter is lost; bodies change their form, but the material element, the simple body, is imperishable, indestructible, and always to be found intact, notwithstanding its numerous transformations. If it is true that in the material world nothing is lost, it is equally certain that neither is anything lost in the spiritual world; that only transformation takes place. Thus, nothing is lost, either of immaterial or material beings, and we may lay down this new principle of moral philosophy by the side of the principle of chemical philosophy established by the genius of Lavoisier.
