VII. Spiritual-Scientific Foundations for a True Physiology

This is something that is manifest also in the dog. I have told you that as soon as the nose smells, the tail wags. Just as with fishes the fins start to move about, so, too, with dogs the tail starts to move. But what does this tail that can only wag really want to do? This is most interesting. The tail can only wag, but what does it really want to do? You see, gentlemen, the dog would really like to do something quite different. If it were not a dog but a bird it would fly under the influence of smell. Just as fishes swim, a dog would fly if it were a bird. Well, of course, a dog has no wings, and so he uses the substituted organ and just wags his tail. It isn't enough for flying, but it involves the same expenditure of energy. In human beings it is the same. Because we always have delicate sensations of smell that we do not even notice, we would constantly like to fly.
