Lecture II

The polarity in man is only comprehensible if we know that his structure is a dual one and that the upper portion perceives the lower. The following too must be considered: the lower functions—one pole of the whole human being—are considered through the study of nutrition and digestion in the widest sense, up to their interaction with respiration The interaction goes on in a rhythmic activity; we shall have to consider the significance of our rhythmic system later. But linked up with and belonging to the respiratory activity there is the sensory and nervous activity, which includes all that appertains to external perception and its continuation and its being worked up in the nervous activity. Thus, respiration and sensory and nervous activity form one pole of the human organism. Nutrition, digestion, and metabolism in its usual sense, form the other pole of our organisation. The heart is primarily that organ whose perceptible motion expresses the equilibrium between the upper and lower processes; in relation to the soul (or perhaps more accurately in the sub-conscious) it is the perceptive organ that mediates between these two poles of the total human organisation. Anatomy, physiology, biology can all be studied in the light of this principle; and thus light is thrown, and only thus, upon the human organisation. As long as you do not differentiate between these two poles, superior and inferior, and their mediator the heart, you will not be able to understand man, for there is a fundamental difference between the two groups of functional activity in man, according to whether they pertain to the upper or the lower polarity.
