Fifth Lecture
Now, the three successive post-Atlantean periods, the primeval Indian, the primeval Persian, the Egyptian-Chaldean, are such that, in the sense sense, humanity has become younger and younger, that is to say, in the second period it did not remain capable of development into those years in which it was still capable of development in the first period, and so on. In the Graeco-Latin period, that is to say, in the period that began in the 8th century BC and ended in the 15th century, it was the case that human beings remained capable of development until the beginning of their thirties. When this period closed in the 15th century, human beings were clearly capable of development until well beyond the twenty-eighth year. Today, as we have emphasized, the ability to develop only extends to the twenty-seventh year and will descend more and more.
