 It is because the silent partner of our mental administration is only the 

 sole head thereof under other guise, in other mood, with other, possibly 

 more playful, occupation, that his dominant habits, interests, endowment, 

 experiences pervade their common business. It is again because the one

 who have intercourse with this concern, as indeed the director thereof 

 himself, have little occasion to come into direct contact with influences 

 and data that do not appear upon the books. It has been our present 

 purpose to set forth, and mainly through the minor departures in 

 thought and behavior, how constantly the subconscious participation per- 

 meates the entire network of the mental business. It is indeed the 

 peculiar virtue of the abnormal method that it illuminates the rule 

 through the exceptions ; and here finds in lapses illustrations of signifi- 

 cant principles that prevail in the normal, well-adjusted conduct of 

 affairs.
