Alvin Plantinga's much heralded religious epistemology is a many-faceted thing. In simplest terms, it is an attempt to free would-be rational theists from the evidentialist requirement for religious belief and to show that they are well within their ‘epistemic rights’ in taking certain beliefs about God as ‘properly basic’. In an early version of his programme, Plantinga sought to achieve both these objectives through a single strategem, namely via the overthrow of ‘classical foundationalism’, an historically wide-ranging approach to epistemology he judges to be, even today, preeminent. Plantinga's frontal attack on his self-styled opposition, however, soon proved inadequate to his task, largely because it exposed his own position to criticism and left pressing questions unanswered. By this time, of course, Plantinga has done much to reply to his critics and to address fundamental questions; yet in so doing, he has adopted argumentative manoeuvres, some quite surprising, that take him considerably beyond his original position. These developments in his proposal are central to the discussion that follows. If we are to comprehend them, however, we must begin where he did, with a critique of classical foundationalism, for in the case of Plantinga's religious epistemology, to trace genesis is to elucidate growth.
