A Story Outline of Evolutioi^ 



The past three generations have left to all future genera- 

 tions more achievements in mechanical progress than all the 

 preceding generations had done. 



Mechanical progress, through the aid of the telescope, 

 has lengthened our vision a million times. Through the 

 radio, we can hear the human voice ten thousand miles away. 

 Through the use of the X-ray and the microscope, we can 

 see objects that no unaided eye can see. The human voice 

 and human vision are both canned and preserved for future 

 generations. By means of medical science, surgery and 

 sanitation, human life has been prolonged so that every 

 normal baby born has a life expectancy many years greater 

 than the preceding generations had. With the aid of the 

 airplane, we can transport our bodies through the air at a 

 greater rate of speed than any living creature has ever 

 traveled before. In this country we now have 30,000,000 

 automobiles, 18,000,000 telephones, 15,000,000 plumbing 

 connections, 12,000,000 radios and many millions of other 

 helpful devices that our grandfathers did not have. We 

 have a billion lifeless mechanical forces doing the lifting, 

 pulling, pushing, carrying and digging work that was for- 

 merly done by the muscular forces of man and beast. 



But how did all these things come to be? Were they 

 evolved out of man's inner consciousness without effort on 

 his part, or are they the result of work, of adaptation, of 

 necessity and of mental growth? The answer to these ques- 

 tions Is obvious. 



Man has divided his mental achievements into various 

 groups such as History, Art, Literature, Science, Religion 

 and Philosophy. These groups are sub-divided Into many
