From the Unconscious to the Conscious 



manifestations in the psychological groups detached from 

 the Self. 



Isolated activity of the cerebral psychism is shown 

 by automatism; or by pseudo-personalities aroused by 

 suggestion personalities of a commonplace kind and 

 inferior order, devoid of originality. 



Isolated activity of the mental elements of the extra- 

 cerebral psychism is the origin of the multiplication of 

 personalities of higher and more complex kinds. 



The phenomenon of incipient mental dissociation 

 with a tendency to duplication, is frequent in normal 

 life, by reason of the complexity of the mentality, of the 

 alternating predominance of certain groupings which 

 may be rivals or antagonistic, and the inability of the 

 Self to bring them into harmony. 



But in abnormal states and in certain predisposed 

 persons this duplication of personality goes to unexpected 

 lengths. 



That true multiple personalities should appear, two 

 conditions are essential. 



Firstly, a liability to decentralisation, and a certain 

 instability of the central direction a weakness in the 

 individual ' autocracy/ 



Secondly, a defect in assimilation of the mental 

 elements by the Self. This second condition is a chief 

 one. Without this defect of assimilative power, there 

 may be decentralisation, but no ' personality ' worthy of 

 the name will appear. 



We have seen that the Self retains the complete 

 knowledge of states of consciousness and assimilates 

 them. If this assimilation is imperfect, these states of 

 consciousness retain an irregular and centrifugal self- 

 activity which tends towards isolated and distinct 

 manifestations. 



The genesis of a secondary personality is then easy to 

 follow. To begin with, there is abnormal activity, 

 a ' parasitic budding ' in the mentality. An ill-assimilated
