IV. Three Epochs of Childhood
Now we come to the animal world and we cannot consider the animals as belonging to the earth in the same way. This is apparent from the mere fact that the animals can move about; in this respect they are independent. But when we compare the animals with man we find something very characteristic in their formation. This has always been indicated in an older, instinctive science, the after-effects of which still remained in the first third of the 19th century. When however a modern man with his way of looking at things reads the opinions expressed by those philosophers of nature who, following old traditions, still regarded the animal world in its relation to the human world, these strike him as being utterly foolish. I know that people have hardly been able to contain their laughter when in a study circle, during the reading from the nature philosopher, Oken, the following sentence occurred: “The human tongue is a cuttlefish.” Whatever could he have meant? Of course in actual fact this statement of Oken's can no longer be regarded as correct, but it contains an underlying principle which must be taken into account. When we observe the different animal forms, from the smallest protozoa up to the fully developed apes, we find that every animal form represents some part of the human being, a human organ, or an organic system, which is developed in a one-sided way. You need only look at these things quite crudely. Imagine that the human forehead were to recede enormously that the jaw were to jut right out, that the eyes were to look upwards instead of forwards, that the teeth and their whole nexus were also to be formed in a completely one-sided way. By imagining such an exaggerated, one-sided development you could get a picture of a great variety of mammals. By leaving out this or that in the human form you can change it into the form of an ox, a sheep and so on. And when you take the inner organs, for instance those which are connected with reproduction, you come into the region of the lower animals. The human being is a synthesis, a putting together of the single animal forms, which becomes softer, gentler, when they are united. The human being is made up of all the animal forms moulded into one harmonious structure. Thus when I trace back to their original forms all that in man is merged together I find the whole animal world. Man is a contraction of the whole animal world.
