One can acquire a feeling for these three planes. How the feeling for the first is obtained has already been shown; it is to be felt as the plane of discriminative Thinking. The second plane, which divides man into front and back (anterior and posterior) would be precisely that whereby man is shown to be Man, for this plane cannot be delineated in the same way in the animal. The symmetry plane can be drawn in the animal but not the vertical plane. This second (vertical) plane would be connected with everything pertaining to human Will. The third, the horizontal, would be connected with everything pertaining to human Feeling. Let us try once more to get an elementary idea of these things and we shall see that we can arrive at something by this line of thought.
