Postmodernism, Reason and Religion

How can we account for the extraordinary strength of Islam in the modern world? Are the views of the Enlightenment still an acceptable basis for social order?

In Postmodernism, Reason and Religion, Ernest Gellner suggests that we face three ideological options at the present time: a return to the genuine and firm faith of religious tradition; the pursuit of a form of relativism which abandons the notion of truth and resigns itself to treating truth as relative to the society or culture in question, and upholding the view that while perhaps there is a unique truth, no one society can fully possess it.
