242 The Evolution Hypothesis. 



sight the language might seem to indicate that there 

 are two unknowable powers manifested in the two 

 classes of phenomena. But such a supposition is so 

 entirely alien from Mr. Spencer's system that we are 

 not entitled to draw the inference. The underlying 

 power is the one unknowable energy immanent in all 

 things. It is only the manifestations that may be differ- 

 enced. Let us fix our thoughts by citing an example. 

 A soldier passes : the perception of him constitutes a 

 feeling of the vivid order. The image remains in the 

 memory and can be recalled at pleasure : when recalled 

 it appears as a feeling of the faint order. Next day a 

 soldier in similar uniform passes. Again a vivid feel- 

 ing is produced. This feeling forms a cohesion with 

 the faint feeling that remains from seeing the soldier on 

 the preceding day. Now, according to Mr. Spencer's 

 doctrine, the vivid feeling is a manifestation of the un- 

 knowable in the non-ego, while the faint feeling is a 

 manifestation of the unknowable in the ego. A rela- 

 tion subsists between the two manifestations : we may 

 ask to which aggregate does it belong ? So far as it 

 is a relation of the vivid feeling it is a part of the 

 non-ego ; so far as it is attached to the faint feeling 

 it must be taken as belonging to the ego. But waiv- 

 ing minute criticism, we ask, How does the manifes- 

 tation in the aggregate called self, differ from that in 

 the aggregate called not-self, as a manifestation of the 

 unknowable ? A nerve-thrill is the outer face of the 

 vivid feeling : a nerve-thrill is the outer face of the
