558 SUMMARY AND CONCLUSION. 



aggregates and their relations to incident forces, there also 

 results variety in their movements. 



The transformation thus contemplated under separate 

 aspects, being in itself but one transformation, it became 

 needful to unite these separate aspects into a single concep- 

 tion — to regard the primary and secondary re-distributions 

 as simultaneously -working their various effects. Every- 

 where the change from a confused simplicity to a distinct 

 complexity, in the distribution of both matter and motion, 

 is incidental to the consolidation of the matter and the loss 

 of its motion. Hence the re-distribution of the matter and 

 of its retained motion, is from a diffused, uniform, and in- 

 determinate arrangement, to a concentrated, multiform, and 

 determinate arrangement. 



§ 188. We come now to one of the additions that may be 

 made to the general argument while summing it up. Here 

 is the fit occasion for observing a higher degree of unity in 

 the foregoing inductions, than we observed while making 

 them. 



The law of Evolution has been thus far contemplated as 

 holding true of each order of existences, considered as a 

 separate order. But the induction as so presented, falls 

 short of that completeness which it gains when we con- 

 template these several orders of existences as forming 

 together one natural whole. While we think of Evolution 

 as divided into astronomic, geologic, biologic, psychologic, 

 sociologic, &c., it may seem to a certain extent a coincidence 

 that the same law of metamorphosis holds throughout all its 

 divisions. But when we recognize these divisions as mere 

 conventional groupings, made to facilitate the arrangement 

 and acquisition of knowledge — when we regard the different 

 existences with which they severally deal as component 

 parts of one Cosmos; Ave see at once that there are not 

 several kinds of Evolution having certain traits in common, 

 but one Evolution going on everywhere after the same
