‘God’ in Public Reason

Abstract

The recent suicide bombings in London by young Islamists should remind Christian theologians that they are committed to a liberal polity of some kind. But is a genuinely theological liberalism possible? Many still think that public reason in a liberal polity must be universally accessible and therefore ‘secular’; and that it requires those with religious convictions to strip their public speech of theology. Such is the position taken by Jürgen Habermas in a recent newspaper interview. But is Habermas correct to suppose that a theological argument must be inaccessible to ‘non-theologians’? This essay returns a negative answer by seeking to demonstrate that a genuinely theological argument — for example, about the legalisation of euthanasia — can be grasped by non-theologians, can engage them, and might even persuade them. It concludes that on this point the late John Rawls has certain advantages over that of Habermas.
