Warner has said that his focus is on the political aspects of Islamic doctrine related to kafirs ( non-Muslims ) rather than on the beliefs of contemporary Muslims . He differentiates Islam as a religion and what he refers to as Political Islam . Warner defines " political Islam , " which he also calls Islamism , " as a belief that Islam should control society and politics , not simply personal religious life . " Warner graduated from North Carolina State University where he got his PhD in Physics and Mathematics in 1968 . After the September 11th Attacks , he decided to make Islamic texts more accessible to the public . He has said that he gained a knowledge of Islam by studying all the Islamic texts he considered relevant from the time he was 30 years old
