Man or Matter: An Introduction to a Spiritual Understanding.

“‘What is science?’ . . . It is a pity the work of Dr. Rudolf Steiner has been overlooked in this respect. Probably the most consistent answer apart from Steiner’s is that of Sir Karl Popper. The object appears to be to find a foolproof criterion that distinguishes genuine scientific statements from others. However, science need not be seen as a system but rather as the activity of scientists. Steiner’s approach takes into account the process of cognition of the researcher, and in particular allows for the evolution of that process. A rigidly conceived scientific method, fixed for all time, may easily become outmoded.” ― Nick Thomas (from the book)

In this third, enlarged edition of Lehrs’ classic study, the reader is led, step by step, to a spiritual-scientific method of investigation. The author demonstrates how one can transcend the boundaries of the physical world to the metaphysical origins of nature and humankind. This is a pioneering new method of training the mind and eye, as well as other human senses, leading to a transformation from our modern “on-looking” consciousness to a new kind of “participative” consciousness.

The beginnings of this method were formulated by Goethe (1749–1832) more than 200 years ago, but his contemporaries offered little in the way of fertile ground for his ideas. It was Rudolf Steiner who recognized the significance of “Goetheanism” for the future development of not only science, but also human culture in general, and who developed Goethe’s work in modern times.

Man or Matter contains the systematic results of the author’s work with the methods of Goethe and Steiner (whom he knew personally). In this unique study, Lehrs addresses himself to anyone―with or without a specialized scientific training―concerned with developing the human power of cognition in the present time.

“Once a being has recognized itself as a product of evolution, it immediately ceases to be that and nothing more. With its very first act of self-knowledge, it transcends its previous limits and must in future rely on its own conscious actions for the carrying on of its development.” ― Ernst Lehrs

This revised edition was edited by Nick Thomas and Peter Bortoft.

Ernst Lehrs (1894–1979) was born in Berlin. Having fought in World War I, he studied science and graduated with a PhD in 1923. He became a senior teacher at the first Waldorf school in Stuttgart, Germany, and in 1935 moved to The Netherlands, where he worked as a teacher, before moving to Britain as a Jewish refugee from the Nazis. In 1952 he returned to Germany and worked as a lecturer at the newly established course in anthroposophic special education in Eckwälden, where he remained until his death.

Nick C. Thomas has been the full time General Secretary of the Anthroposophical Society in Great Britain since 1985. He trained as an electrical engineer in the Royal Air Force, serving as an engineering officer for sixteen years and, subsequently, worked in data communications for Nortel. With Lawrence Edwards and John Wilkes he researched the practical application of projective geometry. His major research interest is the development and application of Steiner's discovery of negative space to building a bridge between natural and spiritual science. He lectures widely on this and on other anthroposophic subjects.
