CONCLUSION 271 



nition of the "ought" and "ought not," afford a 

 sufficient basis for appeals to men not to yield 

 themselves as slaves to heredity. Vice, pauper- 

 ism, and crime will not be eradicated until they 

 are regarded as symptoms of a deep and deadly 

 disease, the tendency to which is remorselessly 

 transmitted, and which can be helpfully treated 

 only by a radical and long-continued change in 

 environment. 



All theories of education should be tested by 

 the facts which have been brought out in this dis- 

 cussion, it being the chief credential of the new 

 education that it studies the child before it gives 

 the child anything to study. 



The welfare and perpetuity of the home re- 

 quire a wise and careful consideration of the two 

 subjects, heredity and environment, in order that 

 those not properly mated may never be married, 

 and that parents may adapt the training of their 

 children to their individual peculiarities. 



That faith alone which of all the religions of 

 the world supplies motives sufficient to inspire 

 even the most degraded to rise against and tri- 

 umph over evil heritage, may be presumed to rest 

 on an immovable foundation. It has the strongest 

 of possible arguments in its favour, the argument 

 of redeemed human lives.
