In the philosophy of religion, Reformed epistemology is a school of philosophical thought concerning the nature of knowledge (epistemology) as it applies to religious beliefs. The central proposition of Reformed epistemology is that beliefs can be justified by more than evidence alone, contrary to the positions of evidentialism, which argues that while belief other than through evidence may be beneficial, it violates some epistemic duty. Central to Reformed epistemology is the proposition that belief in God may be "properly basic" and not need to be inferred from other truths to be rationally warranted. William Lane Craig describes Reformed epistemology as "One of the most significant developments in contemporary religious epistemology ... which directly assaults the evidentialist construal of rationality." Reformed epistemology was so named because it represents a continuation of the 16th-century Reformed theology of John Calvin, who postulated a sensus divinitatis, an innate divine awareness of God's presence. More recent influences on Reformed epistemology are found in philosopher Nicholas Wolterstorff's Reason within the Bounds of Religion, published in 1976, and Alvin Plantinga's "Reason and Belief in God", published in 1983. Although Plantinga's Reformed epistemology developed over three decades, it was not fully articulated until 1993 with the publication of two books in an eventual trilogy: Warrant: The Current Debate, and Warrant and Proper Function. The third in the series was Warranted Christian Belief, published in 2000. Other prominent defenders of Reformed epistemology include William Lane Craig, William Alston, Michael C. Rea, and Michael Bergmann. Concepts, definitions, and background Alvin Plantinga is the best-known defender of reformed epistemology. Reformed epistemology includes two arguments against classical foundationalism. The first grew out of his earlier argument in God and Other Minds (1967). In that work Plantinga argued that if our belief in other minds is rational without propositional or physical evidence, then belief in God is also rational. In his 1993 works, Plantinga argued that according to classical foundationalism most of us are irrational for having many beliefs we cannot justify, but which foundationalism does not accept as properly basic. Plantinga's second argument against classical foundationalism is that it is self-referentially incoherent. It fails the test of its own rules, which require that it be either self-evident, incorrigible, or evident to the senses. In Plantinga's view, warrant is defined as the property of beliefs that makes them knowledge. Plantinga argues that a properly basic belief in God is warranted when produced by
