2. Human Duality

Now, when we ask about the functions of these organs, external science answers by saying that the liver prepares the gall; that the gall flows out into the digestive canal, and takes part in digesting the food in such a way that this may then be taken up by the lymph-system and conducted over into the blood. Much less, however, does external science tell us with regard to the spleen, the third of the organs here considered as inserted in the main circuit. When we reflect upon these organs, we must first give attention to the fact that they have to occupy themselves with the preparation of the nutritive matter for the human organism; but that, on the other hand, they are all three inserted as organs into the circulatory course of the blood. It is not without reason that they are thus inserted, for, in so far as nutritive matter is taken up into the blood, to be conveyed by means of the blood to the human organism in order to continuously supply this with substances for its up-building, these three organs take part in the whole process of working over this nutritive matter.
