In Pentecostalism, Postmodernism, and Reformed Epistemology, Yoon Shin critically builds on James K. A. Smith’s postmodern Pentecostal epistemology with the aid of Reformed epistemology. It takes the reader through an interdisciplinary journey that exposits and illumines the relationship among Pentecostal spirituality, continental and analytic philosophy, postliberalism, moral psychology, and philosophy of emotion. This work clarifies misunderstandings of Smith, in Smith, and between continental and analytic epistemology, constructively and coherently synthesizing the sources through interdisciplinary analysis and thereby demonstrating the value of mashup philosophy. The resulting epistemology strengthens the mostly descriptive epistemology of Smith with the warrant criteria of Alvin Plantinga.
