The same difficulty arises with a ‘new Enlightenment’: its place in a fixed macrosequence and its progression into a new mode. And there is every possibility of devolution from the Enlightenment as history shows us.
The problem is the dialectical complexity of the Enlightenment and its lack of a fixed focus, between the seventeenth and eighteenth century.
Perhaps the point here is the way the new atheists and others have confused the Enlightenment with atheism or anti-religion and this has created a very sterile attitude toward religious history, including that of Islam.
