If, during the course of this trial, we meet with moral evil, if we see vice triumphant and virtue persecuted, if we see the innocent victims of the injustice, the cruelty, or the ignorance of man, we have no right to murmur against Providence, we have no right to utter maledictions against pain, to deplore the scandal of successful and triumphant crime, and of suffering and weeping virtue. We have no right to regret our bodily infirmities, the diseases which lay hold upon us on the Earth, and which afflict us all our lives, or to complain of the weakness of our minds, the decay of our faculties. All these conditions, which are inimical to earthly happiness, are a portion of the series of trials which we have to undergo here below. We ought to bless those evils, and be grateful to those sufferings, for they are the instruments of our eternal redemption, and the more piercing and bitter they are the sooner will come the hour of our deliverance, the happy moment when we shall leave this impure and filthy world which our feet have trodden for a while. Besides, justice will speedily be done. With brief delay the wicked shall be punished for his evil deeds by having to recommence a new existence here, while the good shall be elevated to the upper world, where a new, wide-ranging life awaits him, far more happy and more wise, in truer harmony with the aspirations of our nature than his previous and miserable existence here. Then we shall be born again, radiant and strong, with our memory, our feelings, and our liberty complete. 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.
