The progress of the human race results from the practical application of the law of justice, love, and charity. This law is founded on the certainty of the future; take away that certainty, and you take away its corner-stone. It is from this law that all other laws are derived, for it comprises all the conditions of human happiness; it alone can cure the evils of society; and the improvement that takes place in the conditions of social life, in proportion as this law is better understood and better carried out in action, becomes clearly apparent when we compare the various ages and peoples of the earth. And if the partial and incomplete application of this law have sufficed to produce an appreciable improvement in social conditions, what will it not effect when it shall have become the basis of all social institutions? Is such a result possible? Yes; for as the human race has already accomplished ten steps, it is evident that it can accomplish twenty, and so on. We can infer the future from the past. We see that the antipathies between different nations are beginning to melt away; that the barriers which separated them are being overthrown by the progress of civilisation, and that they are joining hands from one end of the world to the other. A larger measure of justice has been introduced into international law; wars occur less frequently, and do not exclude the exercise of humane sentiments; uniformity is being gradually established in the relations of life; the distinctions of races and castes are being effaced, and men of different religious beliefs are imposing silence on sectional prejudices, that they may unite in adoration of one and the same God. We speak of the nations who are at the head of civilisation (789-793). In all these relations, men are still far from perfection, and there are still many old ruins to be pulled down before the last vestiges of barbarism will have been cleared away; but can those ruins withstand the irresistible action of progress, that living force which is itself a law of nature? If the present generation is more advanced than the last, why should not the next be more advanced than the present one? It will necessarily be so through the force of things; in the first place, because each generation, as it passes away, carries with it some of the champions of old abuses, and society is thus gradually reconstituted with new elements that have thrown aside antiquated prejudices; in the second place, because, when men have come to desire progress, they study the obstacles which impede it, and set themselves to get rid of them. The fact of the progressive movement of human society being incontestable, there can be no doubt that progress will continue to be made in the future.
Man desires to be happy; it is in his nature so to do. He only strives after progress in order to add to the sum of his happiness, but for which result progress would have no object; for where would be the value of progress for him if it did not improve his position? But when he shall have obtained all the enjoyments that can be afforded by intellectual progress, he will perceive that he has not obtained complete happiness, and that this happiness is impossible without security in the social relations; and as he can only obtain this security through the moral progress of society in general, he will be led, by the force of things, to labour for that end, to the attainment of which, spiritism will furnish him with the most effectual means.
