This collection of essays turns on a shift in Romantic studies from viewing wholeness as an absolute value to critiquing it as a limiting construction. Wholeness and its concomitant sense of harmony, rather than a natural given, is a construct that was assembled and disassembled, theorized and criticized, by diverse authors and artists in a wide variety of disciplines and socio-historical contexts, and instrumentalized for diverse purposes. The plurality of these constructions – that Goethe’s Urpflanze, for example, is not synonymous with Friedrich Schlegel’s universal progressive poetry – is but one manifestation of how “assembly” strives but fails to be absolute. The “other” of assembly referenced in the title suggests two divergent but inseparable tendencies: firstly, how a construction can take on the appearance of a natural given; and secondly, how assemblages of wholeness harbor within themselves their own principle of disarticulation. These two tendencies underlie the “inexhaustible” character of Romantic “gatherings”. As a construction passes itself off as nature, the natural fails to account for itself as a whole. The scope of this volume encompasses the establishment, mapping, and interrogation of assembly and its other in German Romanticism through interdisciplinary studies on literature, aesthetics, philosophy, drama, music, synaesthesia, mathematics, science, and exploration.
