Hejinian notes "the important distinction between system (as a network of active procedures and operations) and traditional notions of form (as the shape of appearance of something, often with analogy to a container and thus presumed to be the stabilizing element that keeps content under control. The distinction is akin to one that Friedrich Schlegel makes in his 'Critical Fragments.' The terms he uses there are (as translated into English) coherence and unity" (156)
Unlike unity, "coherence [...] can admit a plethora of materials ('a motley heap of ideas') in 'free and equal fellowship' and 'animated by the ghost of a spirit and aiming at a single purpose'"
"Schlegel is espousing a form, that of 'literary fragments'"
Schlegel: "many a work of art whose coherence is never questioned is, as the artist knows quite well himself, not a complete work but a fragment, or one or more fragments, a mass, a plan"
