Lecture XVIII
Now turn again to the regions outside the earth; let us assume that a special constellation results from the position of Sun and planets, which gives rise to a powerful reflection in the lower abdominal organs of man. What will be the result? It will be relatively unimportant in adults, for in them the upper and lower organic rhythms have reached a certain equipoise. But in children there will of necessity be a vigorous resistance to the cosmic conditions that seek a mirror and replica in the abdominal parts. So if the cosmic configurations act forcibly on the lower abdominal sphere in the child, the upper bodily sphere must defend itself with all its powers. From the convulsive exertion of powers which should not be used so much in the immature upper organic sphere, Cerebral Meningitis can result— Meningitis cerebro-spinalis epidemica. Here, then, you have an illustrative example of the influx of such diseases into man from extra-human nature. If you keep these origins in the background of your thought, as it were, you will be able to reconstruct the whole clinical picture of meningitis, including the typical rigidity of the muscles in the nape of the neck. For this strain and effort of the upper organic sphere in the child, is bound to lead to inflammatory states of the upper organs in the membranes of the brain and spinal cord, and these acute inflammations provoke the other symptoms typical of meningitis.
