HUMAN POPULATION IN THE FUTURE. 495 



and jointly, of counteracting" the separate and joint forces 

 amid which the organism exists." Clearly, then, since all 

 incompletenesses in Man as now constituted, are failures to 

 meet certain of the outer actions, mostly involved, remote, 

 irregular, to which he is exposed ; every advance implies 

 additional co-ordinations of actions and accompanying com- 

 plexities of organization. 



Or once more, to specialize still further this conception of 

 future progress, we may consider it as an advance towards 

 completion of that continuous adjustment of internal to ex- 

 ternal relations, which constitutes Life. In Part I. of this 

 work, where it was shown that the correspondence between 

 inner and outer actions called Life, is a particular kind of 

 what, in terms of Evolution, we called a moving equilibrium ; 

 it was shown that the degree of life varies as the degree of 

 correspondence. Greater evolution or higher life, implies, 

 then, such modifications of human nature as shall make more 

 exact the existing correspondences, or shall establish addi- 

 tional correspondences, or both. Connexions of phenomena 

 of a rare, distant, unobtrusive, or intricate kind, which we 

 either suffer from or do not take advantage of, have to be 

 responded to by new connexions of ideas, and acts properly 

 combined and proportioned : there must be increase of know- 

 ledge, or skill, or power, or of all these. And to effect this 

 more extensive, more varied, and more accurate, co-ordina- 

 tion of actions, there must be organization of still greater 

 heterogeneity and definiteness. 



§ 372. Let us before proceeding, consider in what par- 

 ticular ways this further evolution, this higher life, this 

 greater co-ordination of actions, may be expected to show 

 itself. 



Will it be in strength ? Probably not to any considerable 

 degree. Mechanical appliances are fast supplanting brute 

 force, and doubtless will continue doing this. Though at 

 present civilized nations largely depend for self-preservation
