Library of Science for the Workers 



To understand modern Socialism, you must understand 

 Evolution. Socialists predict the speedy end of the capitalist 

 system as a result of irresistible NATURAL LAWS, the work- 

 ings of which have been studied for two generations since their 

 discovery. Most of the books in which these laws are explained 

 are too difficult to read and too expensive to buy, except for 

 the leisure class. The ten books here described will give you 

 a clear understanding of the great process in which Socialism 

 i» the next step.
