This last course is followed, and the patient is now a Dissociate. In the dissociated stream are:-- 1. The original desires which led to the manifestation of disease--the desire for sympathy, the desire to have her own way, the 'Will to Power.' 2. The knowledge of deceit. 3. The mechanism for maintaining the symptoms--the pains, the paralysis or contracture. This stream is now independent of the main personality and out of its control; as far as the patient knows her pains are real, her deformity is a disease, and whoever doubts it is not only ignorant but cruel. We can now understand the capriciousness of the hysteric, her moods and contrary ways. On the one side is a mind with ordinary motives, and on the other is the split-off portion containing the complexes catalogued above. If the reader thinks this conception brings us back to the old one of demoniacal possession I will admit that the only difference lies in the definition of the demon. The description of this imagined case will perhaps be acceptable to those who believe in the connection between hysteria and malingering. This connection I at one time emphasised, and I still believe that in some cases the repression of a knowledge of deceit plays an important part in the development of the disease. But motives are derived more or less from the unconscious, and when the unconscious elements predominate we approach the condition in which there has never existed any consciousness of deceit. The case of the soldier with an obsession to attack his companion does not admit of the hypothesis of a stage in which the symptom was due to a conscious desire to any end: but his repression might have shown itself, let us suppose, in a paralysis of his legs as a symbol of exhaustion or terror. Then we should have a hysteria in which there had never been any deceit complex, though in the absence of knowledge of the workings of the patient's mind a firm believer in the 'Will to Power' theory might attribute the origin of the condition to a definite desire to escape the strain of war. I can now state that some of the results of conflict between desire and reality form a graduated series, beginning at cases of conscious simulation, then passing on to those of hysteria with repression of the knowledge of deceit, and ending with cases where deceit has never existed; but no one theory explains satisfactorily the origin of all cases of hysteria.
