962 Dynamic Theory. 



work on the vacant territory of brain not before occupied, built up a 

 second person, separate and distinct from the first. It is obvious that, 

 if in these cases the first person had not been inhibited, the stimulations 

 which went into the construction of the second, would have gone to the 

 first, and have been assimilated with it, and the whole have formed but 

 one person. So we have here an absolute confirmation of the con- 

 clusion arrived at before, that the (conscious) personality is nothing 

 more than the aggregation of the sensations of the environal stimuli. 

 Wherever we can get together an association of two or more sensations, 

 we get a sensation of personality, and if we can, in any individual, get 

 anywhere from two to six (or more) different aggregations of brain or- 

 gans, each aggregation disconnected from the rest, we find a separate 

 consciousness of personality going with each one, and the individual is 

 the tenement of two or six or seven persons, as the case may be. It is 

 well if, as in the case of Felida X. and Mary R. , only one of these per- 

 sonalities is awake and active at one time. If, as it no doubt happens 

 in some cases of insanit} T , two or more of these persons are active at 

 once and endeavoring to operate the same nervous and muscular appara- 

 tus, the result might well resemble the antagonisms of seven devils or a 

 legion of them. To make such an individual sane } T OU have only to 

 "inhibit " all of his persons except one. 



Since every idea that enters the brain is at first a foreign element, its 

 sensation is in reality that of a new personalit}', and remains so till it 

 is co-ordinated and assimilated with the first one, mutually modif}'ing 

 and being modified by it. The foreign immigrant to a new country, 

 finds himself in the sudden presence of an avalanche of new ideas, which 

 can be only partially absorbed in his lifetime. I once heard a Scotch 

 gentleman, naturalized in this country, relate with much amusement, 

 how his little son, born an American, came home from school one day, 

 where he had been studying the history of the revolutionary war, and 

 told his father with great glee and exultation how ' l we whipped the Brit- 

 ish. " Fancy the "naturalization" of the father, a "Britisher," ever 

 leading him to feel himself one of the " we " as the boy did. A dif- 

 ferent environment makes a different person. When two are inhibited 

 from each other, they may exist side by side in the same brain. When 

 there is no inhibition, they are superposed one on the other, amalgam- 

 ated and consolidated into one, as far as their elements are assimilable. 



It has been observed that the inhibition in hypnotism is due to the 

 withdrawal of the blood supply from the inhibited parts. When a sub- 

 ject begins to fall into the hypnotic state, his whole brain is in process 

 of being inhibited ; that is, the blood flow is reduced to all of it, ex- 

 cept the one avenue that connects him with the operator. This, I take 

 it, is like a person going into a profound, natural sleep with a single
