 However, justification also proves to be a very elusive concept. In 1979 Alvin Goldman published a paper entitled “What Is Justified Belief?”, which departed from several well-entrenched positions on the nature of epistemic justification. Years later, a number of epistemologists recognized this paper as marking a significant turning point, or “paradigm shift”, in epistemology. Michael Williams (2016: 3) called it “the Reliabilist Revolution”. This turning point has given rise to a lively debate about the kinds of factors that determine the epistemic status of a person’s beliefs or credences.
