J. P. Moreland on Epistemological Particularism"Duhemian and Augustinian Science and the Crisis in Non-Empirical Knowledge" in Life and Learning, Vol. 12 (2002), pp. 203-4.
According to methodism, one must know how one knows before one can know and if one cannot answer the skeptical question of how one knows, then one is defeated by the skeptic. By contrast, epistemological particularism is the view that there are some particular items of knowledge (or justifiable belief) that one can know (justifiably believe) without knowing how one knows them, without the need for criteria for knowledge. According to the particularist, the skeptical question of how people know what they know is a heuristic guide for insight, for extending knowledge from clear paradigm cases to borderline cases. This is done by surfacing from clear cases certain criteria for knowledge (which are justified from prior knowledge of the clear cases and not vice versa), and employing these criteria to borderline cases in order to extend knowledge.
