Now after the cerebral mnemonic accumulations 

 had arisen phylogenetically under direct somatic action, 

 they would finally have become able to represent by 

 themselves, even if all connection with the body had 

 been severed, those former affective tendencies to which 

 they owed their origin. And indeed this is true be- 

 cause of the two fundamental mnemonic laws of (i) 

 the gradually increasing independence of the part with 

 reference to the whole and (2) the substitution of the 

 part for the whole, which arise directly from the fact 

 that every elementary specific accumulation when once 

 deposited is capable of an independent existence. 

 Therefore Sherrington's "spinal" dog, for instance, 

 continued to experience the same repugnance to the 

 flesh of other dogs, to exhibit other similar affectivities 

 and even the same emotions as the normal dog, though 

 all of them are undoubtedly of phyletic somatic origiii. 17 



But this cooperation and this possibility of an even- 

 tual substitution of the affective tendency whose seat is 

 in the brain, for the corresponding affective tendency 

 of somatic origin, does not prevent the former from 

 being entirely in the control of the latter. Therefore 

 modern psychology generally admits that the affective 

 life "has its cause below in the variations of the cenes-
