5. The Idea of Reincarnation and its Introduction into Western Culture. The Heralding of Christianity.

When we think of all the achievements of the spiritual life, all the insight into the spiritual world and conceptions of the universe which have come to birth during the course of human existence, we have, on the one side, a picture of great and significant progress in the evolution of mankind on the Earth; and when this progress is investigated by Spiritual Science, it becomes clear that the human being—the single individual—participates in this general progress in that he passes through the successive epochs and time-periods in reincarnations; in this way he is able not only to preserve everything that his soul has assimilated in ancient and more recent times, but also to play a real part in the whole evolutionary process. Thus when a man has lived as a being of body and soul in one epoch of culture, he does not vanish from the field of evolution, but remains, in order again to take part in what Earth-existence has later become. In a general sense, progress of this kind is certainly to be perceived. But many of our studies will remind us that this progress is not so straightforward a matter that it could be said to begin with the simple and the primitive, rising from thence into the heights; on the contrary, it will be found that progress—indeed the whole process of evolution—is full of complication.
