Among many of his influences, James K. A. Smith set the agenda for Pentecostal philosophy with the publication of Thinking in Tongues, which addressed a wide range of philosophical loci through the lens of Pentecostal spirituality. In particular, he articulated an epistemology called narrative, affective knowledge, one that carefully utilizes the resources from continental philosophy and Pentecostalism. In Pentecostalism, Postmodernism, and Reformed Epistemology: James K. A. Smith and the Contours of a Postmodern Christian Epistemology, while accepting the broader descriptions of narrative, affective epistemology, Yoon Shin critically modifies and strengthens Smith’s epistemology through careful exposition and critique and with the aid of wide-ranging resources, such as moral psychology, philosophy of emotion, postliberalism, and Reformed epistemology. Through his exposition, Shin argues that Smith’s Pentecostal epistemology is not uniquely Pentecostal, but postliberal and postmodern. Against Smith’s insistence that to be a Christian postmodern is to be a relativist, Shin critiques Smith’s misunderstanding of postliberalism and its realist commitment and argues for a performative correspondence theory of truth. Moreover, he expands on Smith’s thin prescription for knowledge by enlisting the aid of Reformed epistemology. Through dialogue with Reformed epistemology, Shin identifies three areas for dialogue between postmodern and Reformed epistemology in service of developing a postmodern Christian epistemology.
