The Secrets of Metals by Wilhelm Pelikan
With the help of metals, humankind has established and ever-progressing position in the world and, in the process, has transformed human civilization and the face of the Earth itself. Furthermore, the harmony and effectiveness of many human bodily processes depend on the marvelous effects of metals. With each passing decade, researchers bring us knowledge of new facets of the cosmos of metals in and around us. Nonetheless, despite all the achievements of chemists and physicists, the world of metals holds many mysteries.
In The Secrets of Metals, Wilhelm Pelikan—in the light of spiritual science—discusses the significance of the classic "seven metals" and their importance for humankind as well as for nature as a whole and the Earth. He also discusses the "newer" metals as well as the virtually unknown "radiation effects of metals—the effects of which Rudolf Steiner used therapeutically. Pelikan's method here is a phenomenological one, in which he helps us try to see natural objects in the Goethean sense, as developed by Rudolf Steiner (see, for example Nature's Open Secret).
