The transition of men from one structure of life to another does not always take place in the manner in which the sand is poured out from an hour-glass,--one kernel of sand after another, from the first to the last,--but rather like water pouring into a vessel that is immerged in the water, when it at first admits the water evenly and slowly at one side, and then, from the weight of the water already taken in, suddenly dips down fast and almost all at once receives all the water which it can hold. The same occurs with societies of men at the transition from one concept, and so from one structure of life, to another. It is only at first that one after another slowly and gradually receives the new truth by an inner way and follows it through life; but after a certain diffusion it is no longer received in an internal manner, nor gradually, but all at once, almost involuntarily. And so there is no truth in the reflection of the defenders of the existing order that, if in the course of eighteen hundred years only a small part of mankind has passed over to the side of Christianity, it will take several times eighteen hundred years before the rest of humanity will pass over to its side; there is no truth in it, because with this reflection no attention is paid to any other than the internal attainment of the truth, and the transition from one form of life to another. This other method of attaining a newly revealed truth and transition to a new structure of life consists in this, that men do not attain the truth simply because they perceive it with a prophetic feeling or experience of life, but also because at a certain stage of the dissemination of the truth all men who stand on a lower stage of development accept it all at once, out of confidence in those who have accepted it in an internal way, and apply it to life. Every new truth, which changes the composition of human life and moves humanity forward, is at first accepted by only a very small number of men, who understand it in an internal way. The rest, who out of confidence had accepted the previous truth, on which the existing order is based, always oppose the dissemination of the new truth. But since, in the first place, men do not stand still, but incessantly move forward, comprehending the truth more and more, and approaching it with their lives, and, in the second place, all of them, through their age, education, and race, are predisposed to a gradation of men, from those who are most capable to comprehend newly revealed truths in an internal way to those who are least capable to do so, the men who stand nearest to those who have attained the truth in an internal way one after another, at first after long periods of time, and then more and more frequently, pass over to the side of the new truth, and the number of men who recognize the new truth grows larger and larger, and the truth grows all the time more and more comprehensible.
