The second kind of Occasion demanding introspection, is the autochthonous emanation of feeling of unaccustomed character. Such feelings occur at the physiological epochs;--but at these times they are readily explained in a familiar and simple way, and hence no supernatural agency is usually invoked. A similar explanation is made readily enough in cases of evident bodily disease, even where mental symptoms are prominent, for it is no longer the custom to speak of demon-possession even in the acute deliria. But even where no physiological epoch or clearly defined physical disease stands forth, unusual feelings are no uncommon phenomenon, and they demand explanation. Such occur conspicuously in the psychopathological syndrome so completely described by Janet under the term psychasthenia. Persons thus afflicted feeling an incapacity and an impediment to their free activity and not recognizing that they are sick, endeavour to interpret their feelings. Of course, the interpretation varies somewhat in accordance with the nature of the feelings, and with the person's information about the world and his psyche. But quite apart from modifications of this type, I have found it very common for patients to declare "I feel as if there was another person in me," or "I feel compelled as if by another agency to act thus." The explanation of a supernatural agent weighing upon them becomes very easy. For the purpose of this discussion, it is not important whether psychasthenia arises purely from degeneration of structure, or from faults in the chemistry of the plasma which bathes the nerve structures, or whether it is a purely psychopathological condition to which the physical phenomena are secondary, as some would have us believe. Our object is merely the setting forth of the fact that it is a diseased condition which disposes its victim towards metaphysical explanations. It is a sort of uneasiness which prevents comfort in the feelings of certainty, in the operations of the intellect and decision of action. The patient finding himself abulic, and perhaps too critical minded to accept the mundane supports in his vicinity, seeks a solace in that which to him seems powerful because incomprehensible, that is to say in something supernatural.
