Since the beginning of 21st century, Eagleton has developed his cultural theory from a new perspective to attack the anti-faith inclination of postmodernism. As a Marxist cultural critic, he explores the historical causes of present global contradiction, criticizes the nature of Western ideas of freedom and reason. He points out that irrational acts based on freedom and reason, but without faith, destroy faith and culture of other nations, leading to conflicts and confrontations between religious extremists and Western society. He strongly suggests that the right way to solve current social problems is to establish faith with reason.
