Recent scholars have called into question the categories “science” and “religion” because they bring metaphysical and theological assumptions that theologians should find problematic. The critique of the categories “science” and “religion” has above all been associated with Peter Harrison and his influential argument in The Territories of Science and Religion (2015). This article evaluates the philosophical conclusions that Harrison draws from his antiessentialist philosophy in the two volumes associated with his “After Science and Religion Project.” I argue that Harrison's project (...) is too skeptical toward the categories “science” and “religion” and places too much emphasis on naturalism being incompatible with Christian theology. One can accept the lessons of antiessentialism—above all, how meanings of terms shift over time—and still use the terms “science” and “religion” in responsible ways. This article defends the basic impulse of most scholars in science and religion who promote dialogue and argues for a more moderate reading of the lesson of Territories. (shrink)
