These nervous forces are transformed into spiritual products.
The base of the anterior lobes of the brain belong to the atonic region—the source of those languid, deranging influences which coincide with morbidity and disease. A disturbance of the corporeal organs, which especially influence this portion of the brain, naturally tends to the development of insanity or imbecility. Morel has traced, through four generations, the family history of a youth who was admitted to the asylum at Rouen while in a state of stupidity and semi-idiocy. The following summary of his investigations illustrates the natural course of degeneracy as it extends through successive generations: immorality, depravity, alcoholic excess, and moral degradation, in the great-grandfather, who was killed in a tavern brawl; hereditary drunkenness, maniacal attacks, ending in general paralysis, in the grandfather; sobriety, but hypochondriacal tendencies, delusions of persecutions, and homicidal tendencies in the father; defective intelligence in the son. His first attack of mania occurred at sixteen, and was followed by stupidity, and finally ended in complete idiocy. Furthermore, there was probably an extinction of the family, for the son's reproductive organs were as little developed as those of a child of twelve years of age. He had two sisters who were both defective physically and morally, and were classed as imbeciles. To complete the proof of heredity in this case, Morel adds that the mother had a child while the father was confined in the asylum, and that this child exhibited no signs of degeneracy. Statistics show that multitudes of human beings are born with a destiny against which they have neither the will nor the power to contend; they groan under the worst of all tyrannies, the tyranny of a bad organization, which is theirs by inheritance. We may represent the tendencies of the anterior portion of the brain by Fig. 79. The functional exercise of the anterior and superior portions of the cerebrum is disintegrating and devitalizing, while the anterior and inferior portions coincide with mental and physical derangement, unless counteracted by opposing forces. It is therefore evident that in any organization, upon which is entailed a perverted or excessive action of this portion of the cerebrum, the tendencies are NON-VITAL, i.e., unfavorable to fertility and physical health.
If the antagonizing regions are well developed, the tendencies are favorable to life.

If this portion of the brain indicates a full development, we say of such a temperament that it is VITAL, because the functions of its nerve-centers are favorable to evolution. As degeneration observes conditions, so endurance and development conform to certain laws, and it is the duty of all truthful inquirers, who believe not only in the progress of human intelligence, but in physical improvement from generation to generation, to ascertain and comply with these essential conditions. When the anterior and middle lobes of the brain are fully developed at their inferior surfaces, it is regarded as an insane temperament, i.e. containing the germs of mental and bodily derangement.
How shall we distinguish the combination of organic elements, if not by the manner in which they characterize the constitution? Every human being is distinguished by natural peculiarities, both mental and physical. These are indicated not only by the color of the eyes, hair, and skin, and the mental expressions, but in the conformation and capabilities of the corporeal system. The color, form, size, and texture of a leaf indicate to the expert pomologist the nature of the fruit which the tree will bear, but how much more important is it to understand the harmonies of human development. If Prof. Agassiz could determine the form and size of a fish by seeing its scales, and Prof. Owen outline the skeleton of an unknown animal by viewing a portion of its fossil, why should not the physician understand the language of temperaments, since it opens to him the revelations of human development? The sculptor blends character with form, the artist endows the face with natural expression, the anatomist accurately traces the nerves and arteries, the physiognomist reads character, which the novelist delineates and the actor personates, because there are facts behind all these, the materials wherewith to construct a science. In organization there are permanent forces which operate uniformly, thus revealing the order of nature.
THE TEMPERAMENTS CLASSIFIED.
We propose to speak of four constitutional variations entitled to separate consideration; the lymphatic, the sanguine, the volitive, and the encephalic. The brain controls all the voluntary, and modifies the involuntary functions of the body. A particular cerebral development modifies the functions of all the bodily organs, and thus tempers the constitution. We shall, therefore, base our classification of temperaments upon the mental and physiological characteristics, which are portrayed by cerebral development. Such an arrangement is illustrated by Fig. 80.
