28 NATURE AND NURTURE 



to show that the terrible fall in our birth-rate since 1877 

 has been a differential fall. It is a fall which concerns 

 chiefly the fitter members of all classes. The fitter of all 

 classes, from the artisan to the executive, have fewer and 

 fewer children, but the unflt maintain their old numbers ; 

 nor is the reason hard to seek, income and wages are no 

 longer proportional to physical or mental fitness. The 

 man and woman who cannot afford to marry are now

 nurture has led us in political and philanthropic action 

 to disregard nature in the belief that improved nurture 

 must involve steady racial progress. If the view I have 

 attempted to put before you to-night be a correct view, 

 then we have spent our energies on grindstone and oil- 

 stone, when the first need was good steel. 



I do not think it too late to rectify this mistake, but 

 I believe that the change of pohcy required ^vi]l not be 

 an easy matter. It is not the poUtician we have got to 

 educate ; his opinions and his actions are in the main 

 dictated by what the mass of the electors desire ; he 

 gives bettered environment, a larger navy, old age pensions, 

 or franchise to women, not because he has studied what 

 makes for or mars national welfare, but because he has 

 studied the number of votes these grants will produce. 

 You cannot expect him to do otherwise, when his political 

 life depends on his plurahty of votes. 



The person we have to educate is the voter, and although
