Evan Fales vs. Alvin Plantinga on Proper Basicality

Evan Fales and Alvin Plantinga recently had an exchange on issues pertinent to Plantinga's account of warrant in Philosophy and Phenomenological Research. Fales raised worries for foundationalist theories of knowledge and justification, and then brought these problems to bear on Plantinga's (externalist) foundationalist theory of warrant ("Proper Basicality", Philosophy and Phenomenological Research 68:2 (March 2004), pp. 373-383). Plantinga recently responded in the same journal ("On "Proper Basicality"", Philosophy and Phenomenological Research 75: 3 (Oct. 2007), pp. 612–621). The exchange is a must-read for those exploring and evaluating Plantinga's religious epistemology.
