The History of Mankind in the Light of Supersensible Reality Research
Scientific theory has brought with it many errors and, above all, has created a certain prejudice with regard to the historical development of humanity. And no attention is paid to how the human soul has changed over time, how it has taken on a different form over the centuries. What people had in earlier times is regarded as if it all came from soul impulses that are always the same. If you believe this, you don't know how the human soul has changed, which was connected to human life in a completely different way back then. Today we only know of such a connection in the youth and childhood of a person. We know how the soul is closely connected with the development of life and how what is called spiritual development often depends on the historical course of life. But by the twentieth year this ceases for the human being; the close connection that can be scientifically traced [of the spiritual-soul with the development of the physical-bodily] ceases, and the spirit begins to develop, and this period then comes to an end by the twentieth year.
