20. The Royal Art in a New Form

It is perhaps known to you that Keely invented a motor[^29] which would only go if he himself were present. He was not deceiving people about this; for he had in him that driving force originating in the soul, which can set machines in motion. A driving force which can only be moral, that is the idea of the future; a most important force, with which culture must be inoculated, if it is not to fall back on itself. The mechanical and the moral must interpenetrate each other, because the mechanical is nothing without the moral. Today we stand hard on this frontier. In the future machines will be driven not only by water and steam, but by spiritual force, by spiritual morality. This power is symbolised by the Tau sign and was indeed poetically symbolised by the image of the Holy Grail.[^30] Man is no longer merely dependent on what Nature will freely give him to use; he can shape and transform Nature, he has become the master craftsman of the inanimate. In the same way he will become the master craftsman of what is living.
