What is the conceptual status of modernity in the Muslim world? Scholars describe Muslim attempts at appropriating this European idea as being either derivative or incomplete, with a few calling for multiple modernities to allow modern Islam some autonomy. Such approaches are critical of the apologetic way in which Muslims have grappled with the idea of modernity, the purity and autonomy of the concept of which is apparently compromised by its derivative and incomplete appropriation. None have attended to the conceptual status of this apologetic itself, though it is certainly the most important element in Muslim debates on the modern. This essay considers the adoption of modernity as an idea among Muslim intellectuals in nineteenth-century India, a place in which some of the earliest and most influential debates on Islam's modernity occurred. It argues that Muslim apologetics created a modernity whose rejection of purity and autonomy permitted it a distinctive conceptual form.
