The Evolution of Mind. 243 



faint feeling. The mode of manifestation in either 

 instance is a certain molecular action in the central 

 ganglion. The actions are localized in the same part 

 of the organism : the molecules are the same ; they 

 are the constitutents of the brain substance : the 

 mode of action is the same the only difference con- 

 ceivable being one of degree. The manifestations of 

 the unknowable in the vivid and faint feelings are 

 not distinguishable in any intelligible manner : as 

 feelings, the manifestations are the inner faces of 

 nerve-thrills ; as nerve-thrills, they are modes of mole- 

 cular motion. The exciting stimuli may be in the 

 one class external to the organism, and in the other 

 internal to it ; but these are no more than variations 

 in the operation of known or knowable causes of the 

 same kind and set in one series, the links of which 

 evolution forbids us to break or to search for a new 

 beginning in the unknowable. Is it not, then, alto- 

 gether futile to lay it down as a first principle that 

 there are two orders of manifestation clearly segre- 

 gated one from the other, each order carrying with it 

 the irrestible implication of some power that mani- 

 fests itself ; " and that by the words ego and non-ego 

 respectively are meant the power that manifests itself 

 in the faint forms, and the power that manifests itself 

 in the vivid forms ? " 



Mind conscious of itself can never be evolved by 

 the clustering of aggregates of feelings. In the pro- 

 cess every characteristic of mind is brought into play,
