Abstract

Peter Harrison's Gifford Lectures demonstrate that the modern concepts of “religion” and “science” do not correspond to any fixed sphere of life in the pre-modern world. Because these terms are incommensurate and ideological, they misconstrue the past. I examine the influence and affinities of Ludwig Wittgenstein's philosophy on Harrison's study in order to argue that Harrison's project approaches Wittgenstein's. Harrison's book is a therapeutic history, untying a knot in scholarly language. I encourage Harrison, however, to clarify how future scholars can progress in their study of phenomena once termed “scientific” or “religious” without succumbing to these same mistakes.
