I. Spiritual Science and the Future of Humanity

None of the old clairvoyant wise men would have come up with the idea that the spiritual world is “on top,” that there is a blue firmament, which encloses our world. The old clairvoyants did not think this way; one only misunderstood them later. There one pointed to the fixed starry sky as a kind of bowl that surrounds our world. It was a great moment, when Copernicus pulled the rug out from under the feet of the human beings as it were. It was a great moment when Gordano Bruno expanded this “bowl” into the infinity of the physical space. However, Giordano Bruno put something else beside the sensory picture. We need only to call a few words of Giordano Bruno in mind and we realise that he accomplished the great action to put a spiritual picture beside this sensory picture. He said that everything that surrounds us in the sensory world is rooted in the thoughts of the universal spirit, which manifest in the outer forms, in that which we perceive with the senses. If Giordano Bruno points to the endless cosmic space and looks for the being of the things manifest to the senses, this was for him, nevertheless, nothing but the embodiment of the thoughts of the universal spirit. Giordano Bruno calls the human mental pictures shades of the divine thoughts, not shades of the outer things. If Giordano Bruno turns the physical view to the outer world, the idea of the universal spirit enters into his soul mysteriously, and the human concepts are not shades of the outer sensory things but the thoughts of the universal spirit.
