Ernst Marti devoted his life to researching the etheric realm--the subtle area between the physical and spiritual. Taking the numerous statements and references by Rudolf Steiner as his starting point, Marti develops our understanding of the etheric world in various fields--from the theory of knowledge to the natural world, music, the realm of color, eurythmy, and medicine. He proposes exciting bridges between the ancient and medieval worldview and the present and future of the natural and spiritual sciences.

Having studied the world of the ethers in volume 1, here Dr. Marti explores the world of formative (or morphogenic) forces. Beginning with the sensory qualities of the visible world, he studies the nature of sense perception, the origin of morphogenic forces, and their phenomenology. In three key sections he examines the formative forces of shape, or form, including growth movements in plants and how they relate to eurythmy and the forces of color; the formative forces of life, or the planetary origin of the morphogenic forces of life and the seven life processes and their relation to rhythm; and the formative forces of substance--the zodiac and the planets and the formative forces of metals.

In this concluding volume of his seminal work, Marti also offers pertinent comments on the nature of potentization in homeopathic medicine.
