All the sad emotions accompany themselves with phenomena of general depression of physiological activity; and that agreeable emotions when they are too prolonged are followed by a period of depression which has the same physical accompaniments. These physical conditions of the emotions are comparable to what is produced under the influence of the absence of physiological excitations under normal conditions: or following excessive excitations. On the other hand, all physical accompaniments of the psychopathies are constituted by troubles which, in their entirety, characterize a deficiency of organic functions. It seems now that one may be allowed to presume that psychical and moral depression, sadness, and discouragement, are, in general, the foundation of all morbid psychical states. In this chapter, the following topics are discussed: intellectual and moral defects correspond to somatic defect; abnormal manifestations of the mind as the consequences of this deficit.
