Enlightenment philosopher David Hume and contemporary thinker Alvin Plantinga share not only the intellectual enterprise of elaborating hermeneutic systems for the understanding of belief, but also the historical circumstance of major epistemological transition. Situated respectively in the ages of deontological empiricism and postmodern information, Hume's natural religion and Plantinga's externalist epistemology can be considered ideas that resist their times just as much as they reflect them. Flood will seek to arrive at an understanding of these thinkers' works and the relationship they bear to their historical circumstances as she traces in them a changing concept of belief.
