Written in 1883 (CW 1) Goethean Science features Rudolf Steiner's introductions to Goethe's works, re-visioning the meaning of knowledge and how we attain it. Goethe had discovered how thinking could be applied to organic nature and that this experience requires not just rational concepts but a whole new way of perceiving.At the youthful age of twenty-one, Steiner was chosen to edit Goethe's scientific writings for the principle Goethe edition of his time. Goethe's literary genius was universally acknowledged; it was Steiner's task to understand and comment on Goethe's scientific achievements. Steiner recognized the significance of Goethe's work with nature and his epistemology, and here began Steiner's own training in epistemology and spiritual science. In an age when science and technology have been linked to great catastrophes, many are looking for new ways to interact with nature. With a fundamental declaration of the interpenetration of our consciousness and the world around us, Steiner shows how Goethe's approach points the way to a more compassionate and intimate involvement with nature.

The Theory of Heat; Second Scientific Course;14 lectures, Stuttgart, March 1-14, 1920 (CW 321)Following his first scientific course the previous year (The Light Course), in these lectures Rudolf Steiner discusses the nature of warmth, its relationship to the four states of matter, to light, to color, and to the subearthly and superearthly realms. He extends the modern ideas of physics through aspects of understanding achieved by spiritual science. With extensive notes and diagrams, this work comprises essential reference material for natural science teachers, as well as interested parents and anyone wanting a deeper understanding of a theory of heat and warmth based on spiriual science."The manifold new aspects of the subject presented placed the element of warmth within the great evolution of the cosmos and then traced it even into the phenomena of life, the concrete processes in the transformation of the states of aggregation in matter, and even into mathematical formulae.... Indications thus given were then worked out during the following years in the Research Institute and Laboratory at the Goetheanum and traced into numerous phenomena of the rhythms of the day and the year, phenomena of life, the most subtle influences in processes of crystallization, and they became useful in the later inaugurated agricultural work." --Guenther Wachsmuth, The Life and Work of Rudolf Steiner (p. 378)This volume is a translation from German of Geisteswissenschaftliche Impulse II zur Entwickelung der Physik II: Zweiter naturwissenschaftlicher Kurs: Die Wärme auf der Grenze positiver und negativer Materialität (GA 321).
