Quintilian, and J.S. Watson. Institutes of Oratory.Edited by Lee Honeycutt, 2010. Kindle Electronic Edition. Book VII Introduction.
In book 7 Quintilian shifts from invention to discuss arrangement. Appropriate connections change a disordered heap of information into an actual work of art (Quintilian VII, Intro. 1). The speech, like a human body, must be assembled appropriately (Quintilian VII, Intro. 2). Therefore, Quintilian will devote book seven to arrangement. He views arrangement as much more an art than a science, as there are infinite ways of arranging a speech (Quintilian VII, Intro. 4).
