Plantinga not only developed his own account of warrant but also mapped the terrain of epistemology. Motivated by Plantinga's work, fourteen prominent philosophers have written new essays investigating Plantingian warrant and its contribution to contemporary epistemology. The resulting collection, representing a broad array of views, not only gives readers a critical perspective on Plantinga's landmark work, but also provides in one volume a clear statement of the variety of approaches to the nature of warrant within contemporary epistemology, and to the connections between epistemology and metaphysics. Positions covered include internalism and externalism, reliabilism, coherentism and foundationalism, virtue theories, and defensibility theories. Alvin Plantinga responds to the essays in his own contribution.
