Reason: The Only Oracle of Man is a hard hitting attack on superstition and "revealed" religion while encouraging the replacement of superstition in our lives and in our ideas of God with God-given reason. 
 
This excellent book, written by the American Revolutionary War hero Ethan Allen, offers Deists, and all freethinkers, loads of ammunition in the fight for reason and progress! Allen pulls no punches as he destroys the arguments of the revealed religionists with nothing but God-given innate REASON! He not only demolishes the dogmas and teachings of the Bible, Judaism and Christianity, and also addresses the ungodly teachings of the Quran and Islam, but he offers reason and Deism for a happy and natural replacement. A great eye-opening read!
