World History in the Light of Anthroposophy
You see, modern civilisation adopts the form of spiritual life that has for so long been cultivated, but real life does not allow this. Civilisation as it now is might continue to progress for a time. During waking life souls would have no inkling of the existence of the Guardian of the Threshold and during sleep would be rejected by him in order to avoid mental paralysis; and this would finally result in a race of men being born in the future with no understanding, no possibility of applying ideas in their future earthly life; and all thinking, all ideation would vanish from the Earth. A diseased, purely instinctive human race would people the Earth. Evil feelings and unbridled emotions without the guiding power of ideas would take hold of the evolution of humanity. It is not only through observation of the souls confronting the Guardian of the Threshold—souls which can gain no entrance to the spiritual world—it is not only through observing this that a sorrowful picture is presented to the seer, but in a different connection there is another factor as well.
