Fourteen lectures by Rudolf Steiner

Translated by George Adams

Stuttgart, March 1 - 14, 1924


Rudolf Steiner discusses the nature of warmth, its relationship to the four states of matter, to light, to color, and to the sub-earthly and super-earthly realms. He strives to extend modern ideas of physics through the understandings achieved by spiritual science. With extensive notes and diagrams, this work comprises essential reference material for teachers of the natural sciences, as well as interested parents and others.
