This is the first of a two-volume edition of Rudolf Steiner’s indications on technology. He not only critiqued the technology of his day, early twentieth century, including the movies, steam engines, telegraphs, automobiles, and trains but he also predicted the development of technologies we are experiencing now in the 21stcentury, and what is yet to come. Electricity-based technology has played an important role in modern civilization, but new forms of etheric technology that harness human and cosmic forces are meant to play an ever-greater role in earth evolution. But these must be developed under appropriate moral and social conditions or they could do more harm than good. This compendium will be essential reading for anyone who wants to understand a spiritual scientific perspective of technology and how it can be developed and used it for the betterment of humanity.
