798. Will spiritism become the general belief, or will its acceptance remain confined to the few?
"It will certainly become the general belief, and will mark a new era in the history of the human race, because it belongs to the natural order of things, and because the time has come for it to be ranked among the branches of human knowledge. It will nevertheless have to withstand a good many violent attacks – attacks that will be prompted rather by interest than by conviction, for you must not lose sight of the fact that there are persons whose interest is to combat this belief, some from self-conceit, others from worldly considerations; but its opponents, finding themselves in a decreasing minority, will at length be obliged to rally to the general opinion, on pain of rendering themselves ridiculous."
Ideas are only transformed in the long run, never suddenly. Erroneous ideas become weakened in the course of successive generations, and finish by disappearing, little by little, with those who professed them, and who are replaced by other individuals imbued with new ideas, as is the case in regard to political principles. Look at paganism; there is certainly no one, in our day, who professes the religious ideas of pagan times; and yet, for several centuries after the advent of Christianity, they left traces that could only be effaced by the complete renovation of the races who held them. It will be the same with spiritism; it will make considerable progress, but there will remain, during two or three generations, a leaven of incredulity that only time will be able to destroy. Nevertheless, its progress will be more rapid than that of Christianity, because it is Christianity itself that opens the road for it, and furnishes its basis and support. Christianity had to destroy; spiritism has only to build up.
799. In what way can spiritism contribute to progress?
"By destroying materialism, which is one of the sores of society, and thus making men understand where their true interest lies. The future life being no longer veiled by doubt, men will understand more clearly that they can insure the happiness of their future by their action in the present life. By destroying the prejudices of sects, castes, and colours, it teaches men the large solidarity that will, one day, unite them as brothers."
800. Is it not to be feared that spiritism may fail to triumph over the carelessness of men and their attachment to material things?
"To suppose that any cause could transform mankind as by enchantment would show a very superficial knowledge of human nature. Ideas are modified little by little, according to the differences of individual character, and several generations are needed for the complete effacing of old habits. The transformation of mankind can therefore only be effected in the course of time, gradually, and by the contagion of example. With each new generation, a part of the veil is melted away; spiritism is come to dissipate it entirely. But, meantime, if it should do no more than cure a man of a single defect, it would have led him to take a step forward, and would thus have done him great good, for the taking of this first step will render all his subsequent steps easier."
801. Why have not spirits taught, from the earliest times, what they are teaching at the present day?
"You do not teach to children what you teach to adults, and you do not give to a new-born babe the food which he could not digest; there is a time for all things. Spirits have taught many things that men have not understood or have perverted, but that they are now capable of understanding aright. Through their teaching in the past, however incomplete, they have prepared the ground to receive the seed which is now about to fructify."
802. Since spiritism is to mark a progress on the part of the human race, why do not spirits hasten this progress by manifestations so general and so patent as to carry conviction to the most incredulous?
"You are always wanting miracles; but God sows miracles by handfuls under your feet, and yet you still have men who deny their existence. Did Christ Himself convince His contemporaries by the prodigies He accomplished? Do you not see men, at this day, denying the most evident of facts, though occurring under their very eyes? Have you not among you some who say that they would not believe, even though they saw? No; it is not by prodigies that God wills to bring men back to the truth; He wills, in His goodness, to leave to them the merit of convincing themselves through the exercise of their reason."
