"In my childhood, the traditional ulema [clerics] – who are so powerful today – were regarded as rather quaint objects and often ridiculed in private. Centuries ago the greatest poets of Persia, like Hafiz and Rumi, stripped away the mullahs’ religious pretensions and exposed their stupidity. Today, however, those same mullahs have taken control of the Iranian republic. The answer lies just as much in the domain of world politics as in theology. Khomeini developed the doctrine known as “guardianship of the clergy,” which gives the mullahs much wider powers than they generally exercised in the past. Instead of being simple religious leaders, they now became political leaders as well. This echoes the broader Islamic fusion of the spiritual and the temporal.… The traditional ulema are indeed a problem, but they are not the biggest one; the biggest problem is Islamism, a radical and often militant interpretation of Islam that spills over from the theological domain into national and international politics. Whenever and wherever religious fundamentalism dominates, blind faith clouds objective and rational thinking. If such forces take hold in a society, they create a mindset unfavourable for critical inquiry, including scientific inquiry, with its need to question received wisdom."
