that the writer \vv\s pvwilv^j^vd to ask at|iu'stii)n ol his own. It touches a

Is there still a possil)iht\' ol lurther e\()l\]n<i; in the cIe\elopinentaI 

 process so clearl\- si't-n ni tiu' brani ol prnnates, so ol)\iously reaching its pres- 

 ent culmination ni the brani ol man -is there still a latent power m the 

 luiman brain tor the expression ol yet unsuspected j:)otcntialities and benelic- 

 ial progress? 



This is a c|uestion w Inch may not be cjuicklx read or soon lorgotten. There 

 is an undeniable insistency about it as it calls attention to the palpable 

 impertections in human organizations. Answered in the negati\e, to what

 ol mankind! This greatest problem ol humanitx' is susceptible ol solution. 

 It awaits onI\ the intelligence, the patience, the persistency and the deter-
