GROWTH IS LOCALIZED IN THE LIVER, ANGER IN THE HEART.
Project Gutenberg EPUB3 edition
Plotinus and Guthrie, Kenneth Sylvan
As the power of growth, nutrition, and generation operates all through the entire body; and as it is by the blood that the body is nourished; as the blood is contained in the veins; and as the veins, as well as the blood, originate in the liver; this organ has been assigned as the seat of that part of the soul called appetite; for appetite is involved in the power of begetting, of feeding and increasing the body. Further as the blood (purified by respiration) is subtle, light, mobile and pure, the heart becomes a suitable instrument for the power of anger, for the blood that possesses these qualities starts from the heart. Therefore, with good reason, the heart is assigned as the seat of the turbulent convulsions of the power of anger.
