motion;' and the change from a concentrated per- 

 ceptible state to a diffused imperceptible state is 

 an absorption of motion and concomitant disintegra- 

 tion of matter. These are truisms. Constituent parts 

 cannot aggregate without losing some of their relative

motion^ and they cannot separate without more relative 

 motion being given to them^' To the former process 



^^ Qualificafr; Mr. Spencer applies the term Evolution ^^ and to the 



latter Dissolution. Both processes are constantly being 

 carried on^ either separately or conjointly, in all exist- 

 ences whatsoever. 



But there are two modes of Evolution which we 

 shall do well to distinguish in their most divergent 

 aspects, although they are connected with one another

 of motion;^ but when integration takes place more 

 slowly, ^either because the quantity of motion con- 

 tained in the aggregate is relatively great ^ or because 

 though the quantity of motion which each part pos- 

 sesses is not relatively great, the large size of the

^ This use of the word ' Evolution/ although arbitrary and open to 

 many objections, was rendered inevitable by previous use and custom. 

 As Mr. Spencer says : — * The antithetical word Involution would much 

 more truly express the nature of the process ' (loc. cit., p. 285).
