This article presents a summary and categorization of recent work on epistemological foundationalism. There is a prominent view that foundationalism is no longer a viable theory. But this view ignores a good deal of recent work in the literature, some of which attempts to respond to standard criticisms of foundationalism by developing more modest versions of the theory. Other epistemologists continue to defend relatively strong, more traditional versions of foundationalism. A brief history of foundationalism is presented. Focussing on work published between 1975 and 1987, the article then categorizes the varieties of foundationalism and discusses the theories of Chisholm, Moser, Pollock and Foley in some detail.
