THE LAW OF EVOLUTION 



are quite conspicuously manifested ; although, 

 as we might expect, these processes are never 

 carried so far here as in the case of organic ag- 

 gregates. It will next be shown that the hypo- 

 thesis is verified, alike by the scanty facts which 

 are at our disposal concerning the genesis of 

 Life, and by the enormous multitude of facts 

 which prove beyond the possibility of doubt 

 that the more complex living creatures have 

 originated by physical derivation from ances- 

 tral creatures that were less complex. Next, al- 

 though — as I have already remarked — the 

 phenomena of Mind are in no sense identifiable 

 with material phenomena, yet as in all our ex- 

 perience there is no manifestation of Mind which 

 is not mysteriously conditioned by movements 

 of matter, we shall find that these super-organic 

 phenomena do not fail to conform to the uni- 

 versal law. It will be shown that the develop- 

 ment of conscious intelligence, alike in the in- 

 dividual and in the race, is characterized bv the 

 change from indeterminate uniformity to deter- 

 minate multiformity. The history of the pro- 

 ducts of conscious intelligence exemplify the 

 same principle ; and nowhere shall we find more 

 striking confirmation than is furnished by the 

 phenomena of social progress. By the time we 

 have narrated the results of this vast induction, 

 we shall be convinced that " from the earliest 

 traceable cosmical changes down to the latest
