I. Occult Science and Occult Development
What, then, is the significance of Spiritual Science or Anthroposophy in the life of the present day, in addition to all that has been said? Through Anthroposophy we become able to use in the right way the organ that will be developed in human beings of the future, the organ for the remembering of former lives on earth. In our present incarnation we must inscribe in the Akasha-substance the knowledge we acquire in order that in our next incarnation we may be able to use this organ—which is developing in man whether he wishes it or not. In the future there will be men who are able to use this organ for remembering past lives and others who are not able. Certain illnesses will appear in the latter, owing to the presence in their physical bodies of an organ which they are unable to use. To have an organ and be unable to use it gives rise to nervous diseases in a very definite form, and those that will be caused in cases of this kind will be far worse than any yet known to man.
