Along with it the fear instinct grows in power, inhibiting all other activities. There is a limitation of the patient’s personal self. The personality becomes reduced to the lowest levels of existence, caring for his own selfish pains and small pleasures, which are exaggerated and magnified to an extraordinary degree. In other words, the _personal_ life of the patient becomes more and more limited as the pathological process goes on. It becomes harder and harder for the patient to take an active interest in life. It is clear that under such conditions the tendency of the patient is to rest and brood about himself, and keep indulging his limited interests, which get still more narrowed as the pathological process becomes more extensive and intensive. Under such conditions it is suicidal to indulge the patient and suggest to him a _rest cure_, a cure which lies along the line of the disease process, thus tending to intensify the disease. What the patient needs is to change his environment, and be put under conditions in which his interests of life can be aroused. His life activities should be stimulated to functioning on the right lines, laid out by physicians who understand the patient’s condition. _Rest is harmful to the neurotic. What the patient needs is work, work, and work._ What we must remember in the treatment of psychopathic patients is the fact that we deal here with the aberrations of the impulse of self-preservation, the most powerful, the most fundamental, and the least controllable of animal impulses, accompanied with the fear instinct, which is the most primitive of all animal instincts. This morbid state of the impulse of self-preservation must be fully realized before any treatment is begun. The physician must also see and study closely the line on which the self-preservation impulse is tending, and comprehend the associations along which the impulse takes its course in the history of the patient and in the symptom complex. What one must especially look after is the elusive feeling of self-pity which manifests itself under various garbs, and hides itself under all kinds of forms. As long as the patient is introspective and has the emotional side of self-pity present, so long is his condition psychopathic.
