I. Spiritual Science and the Future of Humanity

Now the great researchers and thinkers came at the end of the Middle Ages, like Giordano Bruno, Galilei and others who designed a new worldview on the basis of the worldview of Copernicus. However, Aristotle's believers were not inclined to accept this new worldview simply. Galilei and Giordano Bruno pointed to the real world of the senses because now the time began in which the human beings should develop their knowledge by sensory observation and intellect. There it happened that Galilei led a friend who was a good Aristotle believer in front of a corpse and showed him that the nerves originate not from the heart but from the brain. The friend saw this and said, yes, it seems to be in such a way, as if the nerves originate from the brain, but I read something different with Aristotle, and if a contradiction exists, I believe Aristotle.
