There is yet another possibility. Let us take it in its simplest form. Here a “sensory” nerve goes to the spinal cord, and a “motor” nerve leaves the spinal cord, itself a sensory nerve (see drawing). This would be a case of uniform conduction. In fact, all this represents a uniform conduction. And if we take, for example, a simple reflex movement, a uniform process takes place. Imagine a simple reflex motion; a fly settles on my eyelid, and I flick it away through a reflex motion. The whole process is uniform. What happens is merely an interpretation. We could compare it to an electric switch, with one wire leading into it and another leading away from it. The process is really uniform, but it is interrupted here, similar to an electric current that, when interrupted, flashes across as an electric spark. When the switch is closed, there is no spark. When it is open, there is a spark that indicates a break in the circuit. Such uniform conductions are also present in the brain and act as links, similar to an electric spark when an electric current is interrupted. If I see a spark, I know there is a break in the nerve’s current. It’s as though the nerve fluid were jumping across like an electric spark, to use a coarse expression. And this makes it possible for the soul to experience this process consciously. If it were a uniform nerve current passing through without a break in the circuit, it would simply pass through the body, and the soul would be unable to experience anything.
