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).

Contrast between seeing colors and the sensation of warmth. Mechanical theory of heat. The irreversibility of organic and large inorganic processes—integration and differentiation in relation to reality.

2. March 2, 1920: Warmth expansion in one, two, and three dimensions. Ignoring higher potencies cancels out essentials. Individual coefficient of expansion of solid bodies and uniform expansion of gaseous bodies as symptoms. Accademia del Cimento at the transition to a more modern physics. A multitude of detailed observations compared with impoverished concepts. The irregular behavior of water. Cosmic forces in Greek physics and their later displacement into atoms.

3. March 3, 1920: Cessation of temperature rise during melting and boiling. Disappearance of points into a higher dimension. Goethean physics. Temperature as fourth dimension for Crookes. Individual form of the solid body, pressure of the gas.

4. March 4, 1920: Relationship of pressure and volume in gases. The nature of warmth in connection to mechanical facts. The departure from three-dimensional space. The judgment—warmth transforms itself into work. Isolated sense organs for light and tone; the entire human being as a sense organ for warmth and pressure. Conscious, passive concepts filtered out of perceptions of the higher senses. Imperceptibility of the will as one proceeds inward and imperceptibility of electricity as one proceeds outward.

5. March 5, 1920: Higher concepts and sense perception; mathematical concepts and will. Bridging dualism. Memorizing a poem. Abstract thinking and imaginative thinking. Knowledge of space and time on the one hand and knowledge of mass on the other. Kant. Individual form of solid bodies and the surface level of fluids. Gas and cosmos. Water as the cardinal exception.

6. March 6, 1920: Steam pressure. Melting of ice under pressure. Lowering of melting point in an alloy. Lines of fall of solid bodies and their surface levels—in liquids these are materially present. Solid bodies as picture of the fluid—fluid as picture of the gas—gas as picture of warmth.

Rudolf Steiner

Rudolf Steiner (1861–1925) was born in the small village of Kraljevec, Austro-Hungarian Empire (now in Croatia), where he grew up. As a young man, he lived in Weimar and Berlin, where he became a well-published scientific, literary, and philosophical scholar, known especially for his work with Goethe’s scientific writings. At the beginning of the twentieth century, he began to develop his early philosophical principles into an approach to systematic research into psychological and spiritual phenomena. Formally beginning his spiritual teaching career under the auspices of the Theosophical Society, Steiner came to use the term Anthroposophy (and spiritual science) for his philosophy, spiritual research, and findings. The influence of Steiner’s multifaceted genius has led to innovative and holistic approaches in medicine, various therapies, philosophy, religious renewal, Waldorf education, education for special needs, threefold economics, biodynamic agriculture, Goethean science, architecture, and the arts of drama, speech, and eurythmy. In 1924, Rudolf Steiner founded the General Anthroposophical Society, which today has branches throughout the world. He died in Dornach, Switzerland.
