This is clearest in chapters x-xv, which show how power of conception works out in the typical movement (x) of poetic, then (xi-xiv) in that of rhetoric, and then (xv) in their common ground of diction. These chapters, the core of the treatise, confirm by artistic divination the philosophical analysis of Aristotle, and range beyond diction into composition. How, he inquires, are we to lift oratory to the heights? Even as Sappho, he answers, makes us in a single poem feel love; that is, by selecting those characteristic actions which are most salient and gathering them into a single body. “Do you not marvel how she seeks to gather soul and body into one, hearing and tongue, eyes and mien, all dispersed and strangers before?”[3] Poetry gives us the truth of life by bringing into organic continuity what is revealing and significant. What life disperses and interrupts, poetry focuses and brings into emotional sequence and momentum. Its essential processes are to realize these saliences imaginatively and to unify them. “It is survey of the high points, and composition (σύνταξις) for unity.”[4] A simple modern instance is Browning’s “Meeting at Night.” This, the treatise goes on (xi-xii), is the typical method of poetic. The parallel (σύνεδρος) method of rhetoric is the converse; it is amplification. Poetry suggests in a flash; oratory iterates and enlarges. The one is intensive; the other, extensive. The one is compressed; the other, cumulative. Now none of the many and well-known means of amplification is self-sufficient. They all fall short without what we have called heightening. True, amplification and height of style may seem (xii) to amount to the same thing, since the object of both is by definition to invest the subject with greatness; but they differ in method. Height means direct lift (δίαρμα); amplification implies multitude. Therefore the former is often in a single idea (νόημα), whereas the latter always implies quantity and abundance.... So Cicero differs from Demosthenes in grand passages. The [force of the] one is in sheer height; of the other, in volume.... The fire of the one is like lightning ... of the other, like a conflagration.[5] So much for height as proceeding from the whole conception and movement. To return now to diction:
