20. The Royal Art in a New Form
May I be allowed to resume at the remark with which I ended last time,[^28] when I told you where such great control over inanimate Nature leads. Without much fantasy, one can show what is. involved by an example. Wireless telegraphy works across a distance from the transmitting station to the receiving station. The apparatus can be set to work at will, it is effective over great distances, and one can make oneself understood by it. A similar force to that by which wireless telegraphy works will be at man's disposal in a future age, without even any apparatus; this will make it possible to cause great devastation over long distances, without anyone being able to discover where the disturbance originated. Then, when the high point of this development has been reached, it will eventually come to the point where it falls back on itself.
