This formula may be translated into intelligibility as

 The ego or self in the life of Richard Roe is the sum

 the consequences of the thoughts and deeds which have 

 been performed by him and perhaps by others also. 

 Thus each day in his life goes to form a link in the 

 chain which binds his conscious processes together. The
