HUMAN POPULATION IN THE FUTURE. 523 



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, to specialize still further this conception of future pro- 

 gress, we may consider it as an advance towards completion 

 of that continuous adjustment of internal to external rela- 

 tions, which Life shows us. In Part I. of this work, where 

 it was shown that the correspondence between inner and 

 outer actions which under its phenomenal aspect, we call 

 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 evo- 

 lution or higher life implies, then, such modifications of 

 human nature as shall make more exact the existing corre- 

 spondences, or shall establish additional correspondences, or 

 both. Connexions of phenomena of a rare, distant, unobtru- 

 sive, 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 knowledge, or skill, or power, or of all 

 these. And to effect this more extensive, more varied, and 

 more accurate, co-ordination of actions, there must be organi- 

 zation 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 

 on vigour of limb, and are likely to do so while wars con-
