In his influential paper ‘Two Types of Foundationalism,’ William Alston distinguishes two important conceptions of foundationalism: ‘simple foundationalism’ and ‘iterative foundationalism’. SF is the view that there are immediately justified beliefs of some kind or other. IF is the stronger view that certain epistemic propositions are immediately justified. Alston favors a reliability account of immediate justification of the kind defended by externalists such as Armstrong, Dretske, and Goldman. Alston rejects IF by appeal to what he calls the ‘second level argument.’ (...) He claims, further, that since IF is essential to the Cartesian project of reconstructing knowledge, the Cartesian project must be abandoned. (shrink)
