2. Blood and Nerves

The polarity we carry in us manifests in various ways. For instance, there is the material science of the outer world. It has found its culmination, its goal, in present-day natural science, which sees the world as built up out of atoms. These atoms, however, are pure fantasy; they are simply not to be found out there. Why then do we talk about atoms? Because we have in us our nervous system built up out of little globules, and we project this structure on the world outside. The world of atoms out there is nothing but a projection of our nervous system! We project ourselves into the world and thus think of it as consisting of atoms, and of our nervous system as composed of many individual ganglion-globules. Science will always tend to atomism for it originates in nerve substance. By contrast, mysticism, religion, and so forth come from the blood and do not look for atoms but always for unity. These two opposites are in conflict with each other in the world. We do not understand their conflict unless we know it is really the struggle in us between nerve substance and blood substance. There would be no conflict between science and religion if there were none in us between nerve and blood substance.
