IX. Pictorial Representations as a Necessary Educational Tool for Mental Training

We can distinguish between striated and longitudinally striated muscles in the human body; these are voluntary and involuntary muscles. The voluntary muscles of the hand, for example, are striated. The muscles of the intestines, on the other hand, which involuntarily push food forward, are longitudinally striped. The heart is an exception here, and this is a crux for today's physiological and anatomical scientists. The heart belongs to the involuntary muscles, but it has striated musculature. Therefore, our anatomists cannot understand the heart either. They consider all organs to be the same. If we consider the organs spiritually, they may well consist chemically of the same components, but one may be in a descending development and the other in an ascending one. The heart is on the way to becoming a voluntary muscle in the future; its anatomical structure already bears the characteristic features for this. Today, however, it contributes to the effect of emotional experiences on the blood. You can see how, when you feel fear, the blood mass withdraws from the periphery of the body and moves inward, or how, when you feel shame, the blood is driven from the center of the body to the periphery. In the future, in addition to the transformation of the heart, there will also be a transformation of our larynx. Today, the larynx serves to translate my thoughts into words by making the air vibrate. You can pick up and hear my words with your ears; this is caused by the vibrations of the air. The present human larynx is capable of transforming into air vibrations what is going on in the soul. The human body of the future will transform its larynx into a fertilizing organ, and the word, which today only creates in the air, will in the future become creative in our environment. Reproduction will then take place through the larynx, which will create the race of the future.
