Lecture III
Later on came a time, in the Atlantean Age, when it once more became apparent that the human bodily constitution could not be a suitable instrument for the further course of evolution. The human vital organs, and their underlying forces in the etheric body, which for a time had developed in a suitably useful way, had fallen into disorder. For the cosmic forces which had worked on them from the surroundings of the Earth, and whose task it was to bring order into these organs—the organs of breathing, blood circulation and so on—these forces would have developed under the influence of Lucifer and Ahriman in such a way that the vital organs would have ceased to be usable by human beings on Earth. They would have acquired a quite peculiar character. The forces which provide for these vital organs do not flow in directly from the Sun, but from the seven planets, as they used to be called. The planetary forces worked from the cosmos into man. And it was necessary that these forces, also, should be modified. If they had remained under the sway of Lucifer and Ahriman, the vital organs would have become merely organs of greed or organs of loathing. For example, a man would not have been able to restrain himself from hurling himself greedily upon a given dish, while a terrible loathing would have driven him from another. These are things which unveil themselves as world secrets, as cosmic secrets, when we try to penetrate into them clairvoyantly.
