2. The psychic characteristics consist, in the first place, of an emotional state varying from apathetic resignation to despair; some patients are so crushed as to think themselves dead. It has been noted that, in general, persons of a gloomy disposition are inclined to melancholia, while those of a cheerful one rather tend towards mania. In both cases there is an exaggeration of the normal condition. The intellectual disposition consists in the slackening of the association of ideas, in indolence of the mind. Ordinarily, a fixed idea predominates, excluding from the consciousness all that has no relation to it; thus the hypochondriac thinks only of his health; the nostalgic, of his country; the religious melancholiac, of his salvation. Voluntary activity is almost _nil_; aboulia, “the consciousness of not willing, is the very essence of this disease” (Schüle). Sometimes there are violent and unexpected reflex impulses, which are a new proof of the annihilation of the will. To sum up: while normal sadness has its moments of intermission, the melancholiac is shut up in his grief as if by an impenetrable wall, without the slightest fissure through which a ray of joy might reach him. Here arises a question we cannot neglect, because it is connected with one of the principal theses of this work, the fundamental part played by the feelings. Passive melancholia, being taken as the type of the painful state under its extreme and permanent form, what is its origin? There are two possible answers. We may admit that a physical pain, or a certain representation, engenders a melancholic disposition, and poisons the affective life. Or we may admit that a vague and general state of depression and disorganisation becomes concrete and fixes itself in an idea. On the first supposition the intellectual state is primary, and the affective state resultant. On the second the affective state is the first moment, and the intellectual state results from it. This problem, rather psychical than practical, has only occupied a very small number of alienists. Schüle admits the twofold origin.[50] Sometimes the patient, suffering from a painful and causeless depression, which he cannot shake off, inquires no further; but, most frequently, he connects the painful feeling with some incident in his previous or present life. Sometimes, _much more rarely_, the haunting idea is the first to appear, and forms the pivot of the melancholic state and its consequences. Dr. Dumas,[51] who has devoted a special work to this question, founded on his own observation, comes to the same conclusions as Schüle. One of his patients attributed her incurable sadness, in turn, and without sufficient reason, to her husband, to her son, to expected loss of work. In others, the melancholy is of intellectual origin: the loss of fortune, the idea of irrevocable damnation, etc. He is thus led to admit that a melancholia of organic origin is the most frequent, one of intellectual origin the rarest.
