TO THE CLASSES AND THE MASSES 



THE subject treated here calls for no intro 

 duction. Its significance for the man in 

 the street is no less than for the scientist 

 and philosopher, the clergyman and student, the 

 sociologist and journalist. It is of all questions 

 the most fundamental as it is the most far-reach 

 ing in its consequences. It is at the basis not 

 merely of our science and our popular literature, 

 but also of our commercial transactions and our 

 labor troubles, of our public morality and the 

 welfare or ruin of nations. All this is made 

 abundantly clear to the reader in the present vol 

 ume. 



Men believe In God or in materialistic evolu 

 tion. There is no other alternative. Scientists 

 plainly state this fact, and the masses have not 

 failed to grasp it. 



Worker and capitalist, professional man and 

 university professor, the great public and the so 

 cial elite equally absorbed the evolutionary ideas 

 of the nineteenth century. The technicalities of 

 science did not frighten them away. What then 

 they studied is now taken for granted. To-day 

 they are drawing their logical conclusions.
