If we are to understand the specifically modern function of self-consciousness, we must first look to the origins of the concept. Among the key thinkers who elaborated on self-consciousness was the German monk and theologian Martin Luther. Reiner Schuermann’s writings and lectures on Luther therefore offer an innovative reading of the systematic role of self-consciousness in both premodern and modern cultures. The twelfth volume in a planned twenty-nine-part series, Reiner Schuermann: Luther. The Origin of Modern Self-Consciousness sees Schuermann tracing Luther’s conception of the rise of self-consciousness as the subjective reference point. Schuermann then explores this conception in conversation with both the Cartesian cogito and Kantian apperception.
