 the principle of eternal change as illustrated in all 

 phenomena those of the inorganic world, of the 

 world of life, of mind, and of the products of 

 mind. Now, though Spencer was compelled, by 

 the magnitude of his task and by the consequent 

 need for subordination of aspects of evolution less 

 significant to human life, to omit from his system 

 the discussion of evolution as it applies to inani 

 mate nature, he formally stated, in brief, the out 

 lines of the process. And we may illustrate it by 

 reference to the almost infinitely large and the

Less, perhaps, than any other science, has as

 service, however, he did it. The reader will re 

 member the history of the nebular theory of the 

 origin of the solar system. Originally suggested
