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 (1) 
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 origia.’7 
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-
