XIV. Aesthetic Education

If we perform the well-known and common experiment of cutting into the spinal fluid in a case of tabes dorsalis, or if one interprets this disorder realistically, without the usual bias of materialistic physiology, this illness can be explained with particular clarity. In the case of tabes dorsalis, the appropriate nerve (I will call it a sensory nerve) would, under normal circumstances, make a movement sense-perceptible, but it is not functioning, and consequently the movement cannot be performed, because movement can take place only when such a process is perceived consciously. It works like this: imagine a piece of chalk with which I want to do something. Unless I can perceive it with my senses, I cannot do what I want. Similarly, in a case of tabes dorsalis, the mediating nerve cannot function, because it has been injured and thus there is no transmission of sensation. The patient loses the possibility of using it. Likewise, I would be unable to use a piece of chalk if it were lying somewhere in a dark room where I could not find it. Tabes dorsalis is the result of a patient’s inability to find the appropriate organs with the help of the sensory nerves that enter the spinal fluid.
