XI. Progressive Development Through The Different Cycles Of Culture
Our minerals developed entirely upon the Earth; there were no minerals upon the Moon, such as exist to-day. The mineral kingdom is the former plant-mineral kingdom which sank down to a lower stage and which was embedded into the earth as a firm crust. When the Earth cast off the Moon, the substances which remained behind and which later on became minerals, solid metals,. etc., were still an altogether liquid mass. The substances which at that time had already reached a solid state, were hurled out into the cosmic spaces, because, had it kept these substances, the Earth could not have developed, further. Then the first metals which reached a solid state were added. Sometimes they had most peculiar forms! What you now encounter in the mountains as granite or gneiss, at that time revealed quite clearly that it had arisen through the descending development of vegetable beings, of plants which had become stones.
