Upton Sinclair's main concern is social justice. He wanted, through his writings, to make the common people aware of the many hypocrisies of organized religion. He saw the aligment of religion with the forces of capitalism and exploitation of the poor and the working clases of America. He wrote this book in 1918 at the end of World War I and it is a fascinating look at the American left and its thinking during this period of American history. A Collector's Edition.
