Lecture Three

Anthroposophy describes the human physical body, a coarse, material principle, and the more delicate body, which is still material but without gravity—in fact, its tendency is to fly against gravity into cosmic space. The human being has a heavy physical body, which can fall to the ground when not held upright. We also have a finer etheric body, which tends to escape gravity into cosmic space. Just as the physical body falls if it is unsupported, so the etheric body must be controlled by inner forces of the human organism to prevent it from flying away. Therefore, we speak of the physical body, the etheric body, and then the astral body, which is no longer material but spiritual; and we speak of the I-being, which alone is completely spirit. If we want to gain a real knowledge of these four members of the human being—a true understanding of the human being—we might say: The methods of modern anatomy and physiology allow for an understanding of the physical organism, but not the etheric human being and certainly not the astral human being.
