William Cavanaugh’s The Myth of Religious Violence: Secular Ideology and the Roots of Modern Conflict is now out from Oxford University Press:
A growing body of scholarly work explores how the category ‘religion’ has been constructed in the modern West and in colonial contexts according to specific configurations of political power. Cavanaugh draws on this scholarship to examine how timeless and transcultural categories of ‘religion and ‘the secular’ are used in arguments that religion causes violence. He argues three points: 1) There is no transhistorical and transcultural essence of religion. What counts as religious or secular in any given context is a function of political configurations of power; 2) Such a transhistorical and transcultural concept of religion as non-rational and prone to violence is one of the foundational legitimating myths of Western society; 3) This myth can be and is used to legitimate neo-colonial violence against non-Western others, particularly the Muslim world.
