What appealed to me in the lecture-title was simply this, that whereas everyone else sought to prove Einstein right or wrong, here was someone who apparently intended, not merely to add another proof for or against his theory-there were plenty of those already - but to take some steps to overcome it. From the point of view of orthodox science, of course, it was absurd to speak of 'overcoming' a theory, as though it were an accomplished fact, but to me this title suggested exactly what I was looking for.
Although it was the title of this lecture that drew me to the Stuttgart Conference (circumstances prevented me from hearing just this lecture), it was the course given there by Rudolf Steiner himself which was to prove the decisive experience of my life. It comprised eight lectures, under the title: 'Mathematics, Scientific Experiment and Observation, and Epistemological Results from the Standpoint of Anthroposophy'; what they gave me answered my question beyond all expectation.
In the course of a comprehensive historical survey the lecturer characterized, in a way I found utterly convincing, the present mathematical interpretation of nature as a transitional stage of human consciousness - a kind of knowing which is on the way from a past pre-mathematical to a future post-mathematical form of cognition. The importance of mathematics, whether as a discipline of the human spirit or as an instrument of natural science, was not for a moment undervalued. On the contrary, what Rudolf Steiner said about Projective (Synthetic) Geometry, for instance, its future possibilities and its role as a means of understanding higher processes of nature than had hitherto been accessible to science, clearly explained the positive feelings I myself had experienced - without knowing why - when I had studied the subject.
Through his lectures and his part in the discussions - they were held daily by the various speakers and ranged over almost every field of modern knowledge - I gradually realized that Rudolf Steiner was in possession of unique powers. Not only did he show himself fully at home in all these fields; he was able to connect them with each other, and with the nature and being of man, in such a way that an apparent chaos of unrelated details was wrought into a higher synthesis. Moreover, it became clear to me that one who could speak as he did about the stages of human consciousness past, present and future, must have full access to all of them at will, and be able to make each of them an object of exact observation. I saw a thinker who was himself sufficient proof that man can find within the resources of his own spirit the vantage-ground for the deed which I had dimly surmised, and by which alone true civilization could be saved. Through all these things I knew that I had found the teacher I had been seeking.
Thus I was fully confirmed in my hopes of the Conference; but I was also often astonished at what I heard. Not least among my surprises was Rudolf Steiner's presentation of Goethe as the herald of the new form of scientific knowledge which he himself was expounding. I was here introduced to a side of Goethe which was as completely unknown to me as to so many others among my contemporaries, who had not yet come into touch with Anthroposophy. For me, as for them, Goethe had always been the great thinker revealing his thoughts through poetry. Indeed, only shortly before my meeting with Rudolf Steiner it was in his poetry that Goethe had become newly alive to me as a helper in my search for a fuller human experience of nature and my fellow-men. But despite all my Goethe studies I had been quite unaware that more than a century earlier he had achieved something in the field of science, organic and inorganic alike, which could help modern man towards the new kind of knowledge so badly needed to-day. This was inevitable for me, since I shared the modern conviction that art and science were fields of activity essentially strange to one another. And so it was again Rudolf Steiner who opened the way for me to Goethe as botanist, physicist and the like.
I must mention another aspect of the Stuttgart Conference which Belongs to this picture of my first encounter with Anthroposophy, and gave it special weight for anyone in my situation at that period. In Stuttgart there were many different activities concerned with the practical application of Rudolf Steiner's teachings, and so one could become acquainted with teachings and applications at the same time. There was the Waldorf School, founded little more than a year before, with several hundred pupils already. It was the first school to undertake the transformation of anthroposophical knowledge of man into educational practice; later it was followed by others, in Germany and elsewhere. There was one of the clinics, where qualified doctors were applying the same knowledge to the study of illness and the action of medicaments. In various laboratories efforts were made to develop new methods of experimental research in physics, chemistry, biology and other branches of science. Further, a large business concern had been founded in Stuttgart in an attempt to embody some of Rudolf Steiner's ideas for the reform of social life. Besides all this I could attend performances of the new art of movement, again the creation of Rudolf Steiner and called by him 'Eurhythmy', in which the astounded eye could see how noble a speech can be uttered by the human body when its limbs are moved in accordance with its inherent spiritual laws. Thus, in all the many things that were going on besides the lectures, one could find direct proof of the fruitfulness of what one heard in them.2
Under the impression of this Conference I soon began to study the writings of Rudolf Steiner. Not quite two years later, I decided to join professionally with those who were putting Anthroposophy into outer practice. Because it appeared to me as the most urgent need of the time to prepare the new generation for the tasks awaiting it through an education shaped on the entire human being, I turned to Rudolf Steiner with the request to be taken into the Stuttgart School as teacher of natural science. On this occasion I told him of my general scientific interests, and how I hoped to follow them up later on. I spoke of my intended educational activity as something which might help me at the same time to prepare myself for this other task. Anyone who learns so to see nature that his ideas can be taken up and understood by the living, lively soul of the growing child will thereby be training himself, I thought, in just that kind of observation and thinking which the new science of nature demands. Rudolf Steiner agreed with this, and it was not long afterwards that I joined the school where I was to work for eleven years as a science master in the senior classes, which activity I have since continued outside Germany in a more or less similar form.
This conversation with Rudolf Steiner took place in a large hall where, while we were talking, over a thousand people were assembling to discuss matters of concern to the Anthroposophical Movement. This did not prevent him from asking me about the details of my examination work, in which I was still engaged at that time; he always gave himself fully to whatever claimed his attention at the moment. I told him of my experimental researches in electrical high-frequency phenomena, briefly introducing the particular problem with which I was occupied. I took it for granted that a question from such a specialized branch of physics would not be of much interest to him. Judge of my astonishment when he at once took out of his pocket a note-book and a huge carpenter's pencil, made a sketch and proceeded to speak of the problem as one fully conversant with it, and in such a way that he gave me the starting point for an entirely new conception of electricity. It was instantly borne in on me that if electricity came to be understood in this sense, results would follow which in the end would lead to a quite new technique in the use of it. From that moment it became one of my life's aims to contribute whatever my circumstances and powers would allow to the development of an understanding of nature of this kind.

2 The activities mentioned above do not exhaust the practical possibilities of Spiritual Science. At that time (1921) Rudolf Steiner had not yet given his indications for the treatment of children needing special care of soul and body, or for the renewal of the art of acting, or for the conquest of materialistic methods in agricultural practice. Nor did there yet exist the movement for religious renewal Which Dr. Fr. Rittelmeyer later founded, with the help and advice of Rudolf Steiner.
