In locating organs we are to remember that the brain is not a single but a double apparatus--a right and a left brain, each complete in all the organs; consequently, we are in this instance locating our organs in the left hemisphere alone, in which the median line where it meets the other hemisphere is on its right side, and the exterior surface is on its left. An organ located at the median line, or inner surface, as Patience, must have its antagonist at the external or lateral surface, as Irritability.

The right hemisphere has the organs of the left side along the median line, and the organs of its right side on the exterior surface. The left hemisphere has the reverse arrangement. Consequently, the right side of each hemisphere and the left side of the other are identical in function. How then does the right side of one compare with the right side of the other, and the left side with the left? Dr. Gall and his followers have overlooked these questions, and fallen into very great errors in consequence. Gall, for this reason, was mistaken in the natural language of the organs, as will be hereafter shown, having spoken of it as if we had a single brain, and also mistaken in many of the organs concerning which a knowledge of the relations of the two hemispheres to each other would have corrected the errors. There is a striking analogy, or coincidence of function between the two right sides and between the two left sides never suspected prior to my investigations and experiments.

Let us next look for the sentiment of Pride, or Self-respect, which has been called Self-esteem. It is a sentiment of conscious ability. Its character is dignity, rather than selfishness. We readily perceive that it must be in the upper region, but considerably behind the vertical line, where we place the letters S.R.

The question may now arise whether it should be nearer to the right or the left side of the hemisphere, its inner or outer surface. The law governing this matter is that organs of external manifestation are at the median line, but those of more interior and spiritual character are generally at the lateral or exterior surface. Self-respect, or Pride, is an organ of strong exterior manifestation, and is, therefore, at the median line between the hemispheres. Its antagonist must, therefore, be sought at the external or lateral surface, as far below the horizontal division, as Self-respect is above it, and as far forward as Self-respect is backward. Hence we find Humility where the letters Hu. are located.
