1 52 THE NEXT GENERATION 



The power which man has to recognize danger, to control 

 his habits, to decide his own destiny, and to guide the future 

 of the race, turns our thoughts to early evolution times again, 

 and shows how it has come to pass that man is now able to 

 choose either safety or damage for body and brain alike, and 

 how he succeeds in either strengthening or weakening his own 

 character through the highest power that evolution has given 

 him — his brain. The next chapter dwells on this point.
