systems of parts (forming the subject-matter of astronomy 

 and geology), where circumstances not yet recounted permit 

 the retention of a considerable relative motion of parts, the 

 processes of differentiation and integration are quite con- 

 spicuously manifested ; although, as "we might expect, these 

 processes are never carried so far here as in the case of 

 organic aggregates. 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 ori- 

 ginated by physical derivation from ancestral creatures that 

 were less complex. Next, although — as I have already 

 remarked — the phenomena of Mind are in no sense identi- 

 fiable with material phenomena, yet as in all our experience 

 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 

 universal law. It will be shown that the development of 

 conscious intelligence, alike in the individual and in the race, 

 is characterized by the change from indeterminate uniformity 

 to determinate multiformity. The history of the products 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 products of civilization," the law of 

 organic evolution here expounded is the law of all evolution 

 whatever. 



But the universality of this law admits of deductive proof, 

 which may properly be adduced while concluding this chapter, 

 and before entering upon the long course of inductive veri- 

 fication which comes next in order. Already we have seen 

 that the changes which primarily constitute Evolution are
