12. The Relationships Between Spiritual Science and Individual Academic Subjects II

As I said, I will illuminate things aphoristically from different angles; we will come to connections. You know that in today's science, a distinction is made between nerves that spread outwards within the human being and are supposed to mediate perceptions. These nerves are contrasted with another type of nerve, those nerves that are supposed to go from the central organs to the human limbs and so on; these nerves are supposed to have the task of conveying the will, just as the other nerves are supposed to have the task of conveying sensory perceptions. Some very nice constructions have been devised, involving the conduction of sensations to the central organ, their transformation there into volitional impulses, and the innervation of the motor nerves, which are then supposed to mediate what leads from the will to movement and the like. Certainly, the things that are cited to justify the distinction between these two types of nerves are very seductive. I need only recall what one believes, for example, can be studied in a well-known, very painful disease, tabes. One believes that, of course, all the sensitive nerves are intact, that only the motor nerves have suffered damage.
