The natural healthy connection between organic sensations and sense-perceptions is much more strongly displaced when to the insensibility of the sensory nerves, or of the centres of perception, or both, is added an unhealthily modified and intensified vital activity of the organs. Then the organic ego-sensibility, or cœnæsthesis, advances irrepressibly into the foreground, overshadowing in great part or wholly the perceptions of the external world in consciousness, which no longer takes notice of anything but the interior processes of the organism. In this way there originates that peculiar hyper-stimulation or emotionalism constituting, as we have seen, the fundamental phenomenon of the intellectual life of the degenerate. For the fundamental emotional tone, despairing or joyful, angry or tearful, which determines the colour of his presentations as well as the course of his thoughts, is the consequence of phenomena taking place in his nerves, vessels and glands.[246] The consciousness of the emotionally degenerate subject is filled with obsessions which are not inspired by the events of the external world, and by impulsions which are not the reaction against external stimulation. To this is added next the unfailing weakness of will of the degenerate person, which makes it impossible for him to suppress his obsessions, to resist his impulsions, to control his fundamental moods, to keep his higher centres to the attentive pursuit of objective phenomena. According to the saying of the poet, the necessary result of these conditions is that the world must be differently reflected in such heads than it is in normal ones. The external world, the ‘not-I,’ either does not exist at all in the consciousness of an emotionally degenerate subject, or it is merely represented there as on a faintly reflecting surface, by a scarcely recognisable, wholly colourless image, or, as in a concave or convex mirror, by a completely distorted, false image; consciousness, on the other hand, is imperiously monopolized by the somatic ‘I,’ which does not permit the mind to be occupied with anything but the painful or tumultuous processes taking place in the depths of the organs. Badly-conducting sensory nerves, obtuse perceptive centres in the brain, weakness of will with its resulting incapacity of attention, morbidly irregular and violent vital processes in the cells, are therefore the organic basis on which ego-mania develops.
