Since the 1990s, following the end of postmodernism, literary theory has lost much of its dynamics. This book aims at revitalising literary theory exploring two of its historical bases: German poetics and aesthetics. Beginning in the 1770s and ending in the 1950s, the book examines nearly 200 years of this history, thereby providing the reader with a first history of poetics as well as with bibliographies of the subject. The analysis not only shows the differentiation of historical accounts in the field, but also reflects how current literary theory could move forward through the rediscovery of sunken ideas.
