I. Spiritual Science and the Future of Humanity

One example: Aristotle was already at the turning point of the intellectual age, but he still saw back in dark notion at the time in which the human being knew something by clairvoyance, at the processes of human imagining and feeling, at the human evolution, and he describes this. He did no longer have the ancient clairvoyance; he had the tradition only. There he said, if the human being is active in his soul, in his wake state, we deal with the physical body at first, and this has its organs. However, Aristotle would still have been reluctant to regard the material body as the only member of the human being. He pointed to a higher member that has its centre near the heart, and from this supersensible member certain currents originate which go up especially to the brain and spread as supersensible currents in the human body. One still called these currents “cold light” in the Middle Ages that pours forth in particular into the brain to invigorate its physical organs. Still in the Middle Ages people spoke of this cold light which spreads out where the physical heart is.
