Thus far I could go through my own observation and reflexion, but no further. To form a general idea of the deed on which everything else depended was one thing; it was quite another to know how to perform the deed, and above all where to make a start with it. Anyone intending to make a machine must first learn something of mechanics; in the same way, anyone setting out to do something constructive in the sphere of human consciousness - and this, for me, was the essential point - must begin by learning something of the laws holding sway in that sphere. But who could give me this knowledge? Physiology, psychology and philosophy in their ordinary forms were of no use to me, for they were themselves part and parcel of just that kind of knowing which had to be overcome. In their various accounts of man there was no vantage point from which the deed I had in mind could be accomplished, for none of them looked beyond the ordinary powers of knowledge. It was the same with the accepted theory of evolution; as a product of the current mode of thinking it could be applied to everything except the one essential - this very mode of thinking. Obviously, the laws of the development of human consciousness cannot be discovered from a standpoint within the modern form of that consciousness. But how could one find a viewpoint outside, as it were, this consciousness, from which to discover its laws with the same scientific objectivity which it had itself applied to discovering the laws of physical nature? It was when this question stood before me in all clarity that destiny led me to Rudolf Steiner and his work. The occasion was a conference held in 1921 in Stuttgart by the Anthroposophical Movement; it was one of several arranged during the years 1920-2 especially for teachers and students at the Hochschulen and Universities. What chiefly moved me to attend this particular conference was the title of a lecture to be given by one of the pupils and co-workers of Rudolf Steiner - 'The Overcoming of Einstein's Theory of Relativity'.1 The reader will readily appreciate what this title meant for me. In the circles where my work lay, an intense controversy was just then raging round Einstein's ideas. I usually took sides with the supporters of Einstein, for it seemed to me that Einstein had carried the existing mode of scientific thinking to its logical conclusions, whereas I missed this consistency among his opponents. At the same time I found that the effect of this theory, when its implications were fully developed, was to make everything seem so 'relative' that no reliable world-outlook was left. This was proof for me that our age was in need of an altogether different form of scientific thinking, equally consistent in itself, but more in tune with man's own being.
